How to maintain the magnificent orchid in order to burst the pot? Just master these three tricks.

Many people like to raise flowers and plants at home. Do you know about growing flowers? Gentleman orchid has a high ornamental value, it is often used as indoor potted plants, flowering for up to 30-50 days, and open during the New Year's Day Spring Festival, is a very common holiday flower. Raise some gentleman orchids, can let our bedroom show elegant style, but also can enrich and adjust life, add luster and beauty to life.

The orchid is a green plant that is easier to feed, but it takes some skills to raise it well. Here are a few tips to share with you so that we can better protect the orchid.

1. Change soil in spring

Limited by the flowerpot, the soil nutrients in the pot will be absorbed by the plant, and a lot of waste from flower metabolism will be accumulated in the pot, so it is best to change the soil for the orchid every spring and replace it with a new nutrient soil. this can make the orchid grow more exuberantly!

two。 Leaf wiping

The leaves of Cymbidium are broad and have a certain effect of detaining dust, so very often there will be some dust accumulation on the leaves of Cymbidium, affecting the photosynthesis of Cymbidium. Usually, you can wipe the leaves of Cymbidium. This can make the leaves of the plant look more oily and bright, especially we can wipe the leaves with beer dilution, which can play the effect of fertilization outside the roots and make the leaves more thick and greenish.

3. Base fertilizer application

The flowering of Cymbidium needs a lot of nutritional support, so when potting it, you need to add some base fertilizer, and it is best to give it some fertilizer before flowering, mainly phosphorus and potash fertilizer. this is more beneficial to the flowering of Cymbidium.

In addition, Cymbidium prefers slightly acidic soil, so usually two drops of salt-free vinegar can be dropped properly when watering flowers, which can play a role in regulating soil acidity and alkalinity. You can also use fermented rice water to water the flowers and provide adequate nutrition for the orchid.

Flower cultivation tips for 26 families

Inverted Arrow

So that the arrow flowers are large and beautiful, delicate and eye-catching in color, and extensive and easy to raise, many flower friends want to have a pot. The common tactic of family breeding is cutting, but many flower friends report that the survival rate of cutting is not high, and their roots will rot if they are not careful, so cutting has been in vain for many years. Why is the cuttage of arrow lotus easy to rot? Because its fleshy stem is relatively thick, the incision is extremely sensitive to soil moisture-too wet cuttings are easy to rot, and if they are too dry, the branches are shriveled and thin. Even a branch cut that has been alive for a long time will rot if it is not careful, and all previous efforts will be wasted. There is a wonderful way to solve this problem, that is, reverse insertion.

The method is simple: cut the 10-15cm cutter with a sharp knife (the part with a leaf tip at the top), and then insert it upside down into the soil, with a depth of about 6-8cm. Because it is inserted upside down, the incision is exposed. At a suitable temperature, it can take root and survive in about 20 days, and new branches can sprout in a month and a half. At this point, you can safely turn to normal management.

Attention: 1. Be careful when watering or spraying water, do not spray to the upward incision.

2. there is no need to control the water, you can see the dry and wet as soon as you come up.

3. The cutting substrate does not need sand or plain soil, but can be cut directly in the fertile and loose soil.

4. Insert as you cut, and the cuttings need not dry in the shade.

5. The cuttings from the new root to the old will naturally shrink and dry up in the future, and the new branches will take their place.

Second, the epiphyllum blossoms when fed with fat meat

People have their own hobbies, plants are no exception. For example, gentleman orchids like to drink, but epiphyllum is addicted to fat meat. During the growing period, it is often fed with some fat meat, which can not only make its plants green and shiny, but also blossom as many as 5-6 times, with large and many flowers. The specific operation is simple: soak the fat meat in boiling water and remove the salt, or boil the waste lard on tripe in water and then cool it. Then use appropriate tools to insert several holes in the pan pot, 2-3 cm in diameter, then cut the fat or waste lard into tablets, pour it into the hole, and cover the surface with about 3 cm of soil. Main points: 1. The effect is better after adding a little potassium dihydrogen phosphate. 2. Generally speaking, flowerpots with a diameter of 15 centimeters only need to insert two holes and three holes of 25 centimeters. By analogy, the fertilizer effect can be used for the growth of epiphyllum for one year. 3. Must be cooked and chopped, otherwise the decomposition rate is too slow and it is easy to attract insects and ants. 4. Using the waste oil in the oil collecting cup in the range hood, the effect is also very obvious.

Third, filling duck fattening rose

The method of filling duck and fattening rose is aimed at the situation that the nutrients of large rose are difficult to meet the growth of rose due to the limited basin soil, which can make your rose flowers big, gorgeous and energetic. Interested friends might as well give it a try. In early spring, put on or turn the basin before the rose is about to sprout, and apply enough fermented base fertilizer at the bottom of the basin. two。 The second step is to sprout. When sprouting, apply 1-2 times urea or amine sulfate and other solid nitrogen fertilizer, in strict accordance with the proportion of water application instructions, not too thick, otherwise the root will be burned. Dozens of buds can be densely grown about a week after application, and the buds should be thinned appropriately according to the plant size and shape. 3. The third and most important step is spoon feeding:

A. after germination, we should first fully strengthen the supply of nitrogen fertilizer to make the new buds thrive. Irrigate with diluted fully fermented soybean cake liquid, spray leaves and shoots with urea solution of 1 to 1000, and use them alternately once a week.

B. when the new buds grow to about 2 inches, they begin to switch to fertilizers based on phosphorus and potassium fertilizer. Apply diluted fish intestine fertilizer or other phosphorus and potassium fertilizer to the basin soil and spray the leaf surface and branch end with 1max 1000 potassium dihydrogen phosphate, alternating once a week. In this way, a bud will soon appear at the end of each branch. For the uniform distribution of buds, buds can be thinned properly.

C. still use phosphorus and potassium fertilizer alternately every other week to facilitate the next batch of flowers to bloom. In the meantime, nitrogen fertilizer is applied every other month or so. Explanation: organic fertilizer is applied in basin soil, inorganic fertilizer is applied on leaf surface, do not increase concentration at will; in case of heavy rain, it is necessary to avoid rain or shelter rain to prevent basin soil and nutrient loss; it is better to add a certain proportion of briquette ash to basin soil, which is not only breathable, but also has the function of absorbing nutrients, and the release is more balanced.

Fourth, drink to the gentleman orchid-- drunkenness to promote flowers

Gentleman's Ye Ye, its stem Pavilion, flowers red, shining; the whole appears elegant and dignified, especially suitable for indoor desk display, ordinary families like to raise it a few pots. However, there is often such a situation: the flowers are in full bloom when they are bought, but the flowers do not bloom and the leaves do not grow after the flowers, which seems to have become stiff seedlings. Is there any way to change this situation? Yes, this is the way to get drunk and promote flowers:

Liquor should be used, regardless of height or low degree. Yanghe Daqu is fine, so is Erguotou. If you have the economic strength, he also welcomes Maotai. After the Qingming Festival and before the late autumn, pour a glass of liquor into the magnolia basin every now and then, and be careful not to splash on the plant. In this way, after seven or eight days, you can see the effect: foil emerges, new leaves grow, stiff seedlings, resurrection. If dealt with according to the law, the magnolia will grow better and better, and the flowers will bloom like a torch.

Note: this method is very safe, there is no need to worry about the burning of magnolia. But it has not been tested on other flowers and trees, so please use it with caution. If you have no experience, you can use a small amount of it at longer intervals to make sure it is foolproof. At the same time, it can be temporarily suspended after it takes effect.

5. Two small ways for Narcissus to promote flowers and prolong the viewing period Narcissus has won people's love for its graceful grace and jade clean and clear charm. Therefore, during the New Year's Day and Spring Festival, it is the top grade for decorating the living room and desk. However, although the daffodils raised by some people are lush and green, they do not blossom, or they wither soon after they bloom. Is there any way to promote the flower and prolong the florescence? Yes! 1. Soapy water to promote flower daffodils contains a plant alkali, which can promote plant growth and development. Soapy water is an alkaline solution, and after daffodils are inhaled, it increases the plant alkaloids in the body, so that vegetative growth can be quickly transformed into reproductive growth, so that an appropriate amount of soapy water plays a role in promoting flowers. 2. Aspirin extends the viewing period. Grind one or two pieces of aspirin into small particles and sprinkle them into the daffodil basin. The salicylic acid component in aspirin can promote plant flower bud differentiation and flowering, so it can make the daffodil flowers large and bright, and prolong the viewing period. Putting some salt in the daffodil pot can also promote flowers and make flowers live longer. In addition, after the daffodil blossoms, put it in a cooler environment, the effect is also good.

6. Thousands of miles with inserts

Whenever you go on a business trip thousands of miles away, or visit a scenic resort, have you ever seen strange flowers and plants that fascinate you? As a flower fan, you must want to have one, too. Locally, you can press strips and cuttings. But in faraway places, how do you keep the cuttings without losing water, and how do you bring them home smoothly? Here's a simple way to do it: moisturizing is a problem with inserts thousands of miles away. Although it can be moisturized in a plastic bag, it is airtight, and sometimes the cuttings will rot. To moisturize and keep the cuttings fresh, you just need to buy a few fresh cucumbers and the problem will be solved. Cut the leaves off the branches, leave the petiole, and insert them from one end of the cucumber flowering, which not only maintains the moisture of the cuttings, but also prevents it from rotting (because there is an ingredient in cucumbers that can kill bacteria). In this way, as long as the cucumber does not rot, the cuttings will be fine, no matter thousands of miles, you can take it home and survive as you wish.

7. Skillfully wash old flowerpots

After a period of time, there will be more old flowerpots: some dead flowers and trees, or the remaining small flowerpots after turning the pots. It is a pity that these old flowerpots are discarded, and it is very troublesome to clean them if they continue to use (be sure to wash off the white dirt formed on the surface that hinders the breathing of flowers and trees; second, it can remove insect eggs and miscellaneous bacteria; third, it is for the sake of beauty). Don't worry, here's a simple cleaning trick:

Add a certain proportion of ferrous sulfate to a container full of water, and then put the old flowerpots together in the order of size, with the big ones at the bottom and the small ones at the top, soaking together in the solution of ferrous sulfate. After about three days, the dirt on the surface of the flowerpot can be washed clean with a brush. The reason is very simple, ferrous sulfate solution is slightly acidic, the white scale on the edge of the basin is alkaline, as soon as the two are neutralized, it is very convenient to clean.

After using this method, the flowerpot can be kept clean and beautiful for a long time. Thirdly, the basin is slightly acidic, which is also conducive to the growth of flowers and trees.

After the new flowerpot is treated with this method, it can have the same preventive effect.

Eight: bury quail eggs alive and fulfill your dream of growing flowers for lazy people.

Not only want to raise good flowers, but also dislike the trouble of fertilizing, but also want to stay away from the dirt and stench of fertilizer, is there any good way? Yes! Here is a method:

Buy a few quail eggs, first gently break the small end, pierce the intima with a toothpick, when turning the basin for soil, put the quail egg small end up, gently place on the basin bottom culture soil 2 cm, and then fill it with soil normally.

Because the culture soil contains a lot of organic matter, and the basin soil is in a moist state for a long time, with the increase of temperature and the role of fungi, the egg liquid continues to decompose and spill out from the fine cracks to be turned into fertilizer for the root absorption of flowers and trees, which well meets the needs of flower growth. In the middle of summer, most flowers and trees enter the prosperous period of growth and need more fertilizer, which is also the period of active bacterial growth, and the decomposition of egg fertilizer is accelerated to ensure the supply. A small quail egg can basically maintain fertility for 1-2 years. Generally speaking, this method can not apply organic fertilizer all the year round, but when the egg fertilizer has not taken effect soon, we can apply some chemical fertilizer and so on. In this way, the ripening process of laying eggs is completed in the eggshell, so there is no case of raw fertilizer burning roots. In addition, after the eggshell is decomposed, it is also a good calcium fertilizer.

(note: the number of eggs depends on the size of the flowerpot. If one is put, it can be placed in the middle of the pot; if more than two are used, it can be placed symmetrically, 2-4 cm away from the edge of the pot. )

9. Mix the seeds with oil first in spring sowing

In spring sowing, people may encounter the following problems: some flower species emerge a few days after sowing; some flowers, such as magnolia, cyclamen, and asparagus, sprout slowly before they appear after thousands of calls; and some do not see you in the autumn, and do not sprout at all. Is there any way to improve it? Please try mixing oil with flower seeds--

Specific practice: first soak the seeds in warm water with a water temperature of about 35 degrees for 24 hours, then remove the flower seeds and wrap them in a dry cloth to dry the outside water; then mix the flower seeds with some clean cooking oil (such as soybean oil, rapeseed oil and sesame oil, etc.), and then you can sow the seeds according to the usual method.

Do not underestimate this small method, it can make the seeds that are not easy to germinate emerge about 20 days ahead of time, and the seedlings thrive and grow fast; in addition, it also has a very good effect on improving the germination rate.

X. a new method of air permeability for porcelain and plastic pots

The tile basin is breathable and comfortable, but the ornamental is poor; the porcelain basin is strong and beautiful, the plastic basin is light and cheap, but it is not very breathable, all in a word, there are some imperfections. In fact, as long as you use your brain, you can turn a disadvantage into an advantage. Before turning the pot in early spring, prepare some styrofoam (there are many in the electrical packing box) and cut it into small pieces the size of tangyuan. When turning the pot, use a thick piece of paper to make a circle according to the inner diameter of the flowerpot, and then place it in the flowerpot (leave some space between the paper circle and the flowerpot). Then the plastic fragments can be filled into the gap between the two, inside the paper circle, and planted as usual, so that the whole task of turning the basin is completed. There are plastic fragments on the inside of porcelain pots and plastic pots, which greatly increases its air permeability and has a very good effect on the growth and development of flowers. (plastic particles can also be used at the bottom of the basin)

11. Broken bricks and tiles grow flowers more colorful

Broken bricks and tiles grow flowers more colorful. If you don't believe me, try it. Growing flowers in the city, the soil is very precious. Some people continue to use the old soil after turning the basin, in fact, it is not as good as broken bricks and tiles. Broken bricks and tiles are easy to pick up and can be found everywhere. Specific method-beat the waste bricks and tiles into pieces, about 0.2-0.5 cm in diameter. When planting flowers, the smaller and powdery ones are placed near the roots of the plant, and the larger fragments are placed at the bottom of the pot or other parts. Other practices are like planting with soil. Raising flowers with broken bricks and tiles has the advantages of breathability, water conservation and fertilizer conservation. Because there are many tiny voids in broken bricks and tiles, and their adsorption capacity is particularly strong, they can quickly absorb the applied water and fertilizer, which plays the role of preserving water and fertilizer; secondly, because the texture of broken bricks and tiles is firm and unsolid after burning, they are insoluble in water, and many tiny voids in them can be retained for a long time, which is conducive to the circulation of air in the soil. Through the experiment, the pomegranate, Milan and Firethorn raised with broken bricks have developed roots, large flowers, many fruits and long flowering period. Due to the less nutrients in broken bricks and tiles, fertilization should be applied several times more than those planted in soil. )

Sesame oil against ants and aphids there are also "herdsmen" in the insect world, that is, ants. The ant likes to enjoy the "honeydew" secreted by aphids, so it takes great pains to graze everywhere-moving them to various plants and acting as its voluntary bodyguard to fight off various predators of aphids. In this way, our flowers and trees will suffer. Here is a simple and easy way to solve your urgent needs. If your flowers and trees are placed in a separate pot and do not come into contact with other flowers and trees, you can apply sesame oil where the flowerpots come into contact with the ground; if your flowers and trees are placed in multiple pots on the flower rack, you can apply sesame oil where the legs of the shelf touch the ground. Ants usually enter the basin through the hole at the bottom of the basin, and you can also apply sesame oil to the hole at the bottom of the basin. In this way, everything OK, the problem is completely solved, you can rest easy. If you find an ant nest nearby and the mouth of the nest is dripped with sesame oil, the ants dare not come out. The honeydew secreted by aphids is sweet and sweet to ants, but the same fragrant sesame oil is the nemesis of ants. If you still have doubts, you might as well try this.

XIII. Alternative humidification-- escorting the cuckoo on the balcony

The cuckoo is charming and charming, the flowers are in full bloom, and people stop one after another. But the balcony wants to raise the cuckoo well, the humidity problem is a headache. Generally speaking, the climate of the balcony is drier than outdoors, but the cuckoo needs higher humidity, which forms a pair of inexplicable contradictions: either it is difficult to put in the bud, or the red incense disappears. In fact, conditions can be created, and the balcony can also raise cuckoos-find a shallow plate or other utensils slightly larger than the cuckoo pot, put two pieces of wood three or four centimeters high apart, and then sit the cuckoo basin on the strips and add water to the platter. The height of the water is flush with the bottom of the cuckoo basin or a little draught. When the water slowly becomes less exposed, you can wait for two or three days before adding water to the original level. The reason why this method can humidify effectively is that there is stagnant water in the shallow plate all the year round or intermittently, which is equivalent to a simple humidifier with persistent upward transpiration. The higher the temperature, the faster the transpiration, which coincides with the humidity requirements of cuckoos in different periods. Secondly, the water slowly moistens the whole basin wall from the bottom up, so that it is often in a good state of not too dry and not too wet, protecting the basin soil and roots from the influence of dry air. This method can be safely used, and the cuckoo will not rot its roots. Because the water seeps into the basin floor, its depth cannot exceed the depth of the shallow plate below; at the same time, the moisture of the water is completed in a slowly rising way, and there is a certain limit to the amount of water. What's more, the interval water supply gives the cuckoo a chance to adjust the soil air and humidity. This method can make the cuckoo grow as healthily as it does on the ground and blossom normally. Note: 1, when the cuckoo turns the basin, it is best to put some foam fragments and other materials on the bottom of the basin, which is safer. 2. The amount of water to be watered should be reduced appropriately, and the amount of water given at one time is about 2 / 3 of that of ordinary potted flowers. 3. In the high temperature period, the effect will be better with measures such as spraying water to the cuckoo regularly.

14. Old trees are reborn by cutting roots in sections

It is said that all things in heaven and earth have a certain lifespan, and plants are no exception. Although we can not change this trend, but through certain ways, we can still prolong its life. Here is a method.

The so-called lifeline means that life lies in the root, especially in plants. The root is strong, the root is old, and its life is coming to an end. So if we want to prolong the life of plants, we have to think about the roots-during the spring growing season, peel off the potted soil, cut off the whole root of the tree, and then cover it with potted soil, and thin new roots will soon grow from the old roots. This will be done in the next year and the third year, so that after three years, the roots of the trees have all been renewed. Compared with the old roots, the new roots have a significantly stronger ability to absorb water and fertilizer, so it is only natural for the old trees to regain their youth.

In addition, after cutting off the old roots, you can replace them with new soil from 1 to 3. After three years, the basin soil is equal to all the renewal, but also avoids the trouble of turning the basin, it can be said to kill two birds with one stone.

If the vitality of the old pile is OK, it can also be cut short in combination with modeling to make it coruscate new branches.

15. The wonderful use of sawdust turns waste into treasure

In general, when decorating a family, sawdust is often dumped as rubbish afterwards. In fact, sawdust is of great use to us flower growers, we can completely turn waste into treasure, cutting: sawdust is used as the cutting medium of rose, gardenia, pomegranate and other plants, the effect is obvious, far better than soil or water cutting, and fast rooting, many roots, strong plants. What's more, it has a great advantage: after the plant takes root and survives, the sawdust that can be connected to the block can be moved into the basin soil together, so that it does not hurt the root, is easy to grow, and sees flowers and fruits early. Even the cuckoo, which is more difficult to insert, I have tried to succeed. The tender tip of the crabapple with an inch handle can quickly take root. The reason is that sawdust has better water retention and air permeability than soil, and there is plenty of oxygen. Specific approach: after loading the sawdust into the flowerpot, repeatedly irrigate it with boiling water several times to thoroughly disinfect it. After the temperature drops, squeeze out the excess water (so that the wet sawdust can not squeeze the water out of the hand), and you can start cutting, the method is the same as soil cutting. Keeping sawdust moist after insertion will soon take root and survive. This method can be implemented all the year round, but it needs to be placed on the sunny windowsill with heating in the house in winter. 2. As a high-pressure dressing substrate: sawdust is also superior to other substrates because of its loose texture, controllable dryness and humidity, faster rooting, safer and higher survival rate. Specific methods: after the plant is girdled, fill the plastic bag on the bag with a half-mixed matrix of wet sawdust and loess, and then fasten both ends. 3. As fertilizer: wet saw powder is used to make fertilizer, which is nutritious, economical, simple and clean. Specific measures: wet sawdust and an appropriate amount of calcium superphosphate or potassium phosphate or urea and other inorganic fertilizer mixed, organic fertilizer mixed with better, into the plastic bag, tight bag mouth. Turn it over every two weeks to accelerate its uniform ripening, and it can be used in about six weeks in the spring and autumn season. Note: 50% of the soil should be mixed when using it. The above points are listed, but the rest are not overstated. In fact, the use of sawdust is more than that. We can use our brains and try it. (alas, forget the important point, now add that sawdust should be fermented before use. )

If you want good winter flowers and trees, leave some grass in the basin

The reason for saying "stay" rather than "planting" is that there are often some weeds in our pots that come uninvited and enjoy themselves and grow luxuriantly. The general reaction of flower friends is to hate the itching of the teeth, must want to get rid of it quickly, the so-called eradication is also. It is not strange for me to say that it is strange, in view of the fact that florists often propose that it is difficult to master the scale of watering in winter. The roots are rotten, the leaves are falling, and the flowers are dying. Is there any easy way to make people grasp the scale of watering quickly? Yes, please show mercy and leave a few weeds in the basin to get rid of the roots. Generally speaking, most varieties of plants are dormant or semi-dormant in winter, the water supply does not need too much, as long as the soil is slightly moist. However, many flower friends often rush to water the flowers as soon as they see the soil white, thinking that they may dry out, but in fact, the soil is white, and the middle is still very wet, so it is strange that there is nothing wrong with the flowers and trees. Leave some grass in the basin, not all grass, but the green grass that is cold-resistant and upright in winter. It's not as many as possible, as long as there are three or five trees. When is it time to water? When shouldn't I water it? Look at the grass! If the grass is still green, don't water it; if the grass is dead and tired, water it immediately. The yardstick is that simple! Leaving some grass in the basin can do more than that: winter protects against the cold, summer protects against the sun, and decorates the basin-what do you want to see in the bare soil? In addition, when loosening the soil, a shovel of grass buried in the soil is green manure, which is enough to compensate for the loss caused by weeds competing for fertilizer with potted flowers. I've been watering it this way for more than a year, and it works all the time. If you believe, you can try it, too. Note: 1. Plants that are still blooming and fruiting in winter are not in this case. 2. This method is also applicable in other seasons.

Seventeen. Reproduce green bamboo forest by burying joint

"it is better to eat without meat than to live without bamboo." this is true of the ancients, and it is the same with people today. Green bamboo is also one of the varieties of modern family greening around the house or in the environment. Planting trees often takes ten years, while planting bamboo can often create a shady and evergreen environment in one or two years. Moonlight melting night, whirling bamboo shadow swaying outside the window, can add infinite interest. Planting a few poles of bamboo in a pot, decorated with one or two quartz stones, is also a desk love in the hearts of many flower growers. Bamboo is generally propagated with whips, and a few of them are sown with seeds. My breeding method is rare (taught by my cousin), but it works very well-it is simple and easy, and the survival rate is high. Bamboo lovers might as well have a try. In the rainy season of early spring, the mother bamboo with full buds is sawed off between the two sections (that is, leaving a node scar in the middle); then the two ends of the bamboo tube are filled with moist sand, filled and compacted, and then sealed with clay at both ends of the tube, this is the first step. Secondly, choose loose and permeable sandy loam soil, according to the thickness of the bamboo tube, dig a ditch with a depth of about 10 cm, bury the treated bamboo tube flat in the ditch, press it slightly, and then pour water through it, so that the work is done. Remember to bury the bud upward when burying the festival, and never bring it down. Bamboo knots can sprout in about 25-30 days, such as bonsai, you can choose the rainy season. Main points ~ 1. Select coarse bamboo for bamboo cultivation and fine varieties for pot cultivation. 2. When sawing the bamboo tube, be careful not to crack it so as not to hurt the bud. 3. Watering should be dry and wet. 4. After burying, it is best to cover it with some bamboo branches or withered grass to block part of the sun.

18. Home-made rooting agents take root quickly and more

The weather gradually warmed up, the earth warmed up, and it was a good season for cutting. There are a variety of cutting methods, generally like soil or water cutting. However, the operation methods of each person are different; coupled with the differences in plant varieties, it is easy and difficult to take root, which makes the survival rate different. In order to solve this problem properly, everyone likes to use rooting agents such as naphthalene acetic acid before cutting, which is really effective, and the rooting survival rate is also improved. But if the place is remote and the goods are out of stock, what if we can't buy it for a while? Don't worry, let me introduce several home-made rooting agents to you. You don't need money to buy them, and the effect is no worse than the ones you bought. (1) Phosphate Fertilizer solution. As mentioned above, rooting agents such as naphthalene acetic acid are actually a kind of rooting hormone. In fact, phosphate fertilizer solution has the same effect. Because, "phosphorus" this substance can effectively promote plant cell and tissue growth and development, promote plant wound healing and rooting. Specific methods: before cutting, dilute the phosphate fertilizer solution with water, proportion water 7 to fertilizer 3, then soak the pre-treated cuttings (root) into the fertilizer, the water part accounts for 1 stroke of the cuttings, take out and rinse with clean water 2-3 hours later, then cut according to the routine cutting. General varieties, such as camellias, roses, etc., can take root 10-22 days earlier by cutting with this method, and the roots develop well and grow vigorously. (2) White sugar liquid is also a good rooting agent, which has been tested by many people and the effect is obvious. Specific practice: first use hot water to melt the white sugar, the proportion is water 9 sugar 1, after the sugar water is cooled, the cut cuttings can be immersed in it. Take out about 40-60 minutes, rinse the incision with clean water, and cut off part of the incision with a sharp knife, then you can cut it according to the routine cutting. After the above treatment, the survival rate of plants cut is much higher than that of general cuttings, even the cuckoos and camellias, which are more difficult to take root, can reach more than 90%. (3) Willow extract is a good plant growth agent, and its liquid is rich in growth hormone, so it can survive and has strong vitality. Specific methods: take a number of willow branches and leaves, smash the branches with a hammer, and then immerse them in water. One day later, the branches and leaves are removed, and the water is the willow extract. The cuttings can be soaked in the next day, soaking for about 1 day, (it doesn't matter if it takes a long time, willow sap has ingredients to inhibit the reproduction of bacteria) and then cut according to the routine. The roots are fast and many, and the plant grows healthily.

19. "amphibious" cutting method

Cutting is a simple and easy propagation method that everyone is willing to use; it is now a good time for cutting, so my posts are all related to cutting. I recommend it to you. I hope it can be helpful to you. The two most commonly used methods of cutting: soil cutting and water cutting have their own advantages and disadvantages. But both have a difficulty ~ ~ the basin must be moved after taking root. Because the new root is relatively delicate, coupled with the operation of some people are not very skilled, often wasted previous efforts, failure is on the verge of success, which is very frustrating. A cutting method introduced below does not need to move the basin after rooting, so the survival rate of cutting is greatly improved. I call it "amphibious cuttage". The methods are as follows: 1. Find a flowerpot of the right size and seal the bottom hole with melted wax. (other materials are also available, but be sure to open them as soon as you need them.) put about 3. 5% of cutting soil at the bottom of the container, which will be covered with about 1. 5% of river sand to fix the cuttings. Then gently pour water to about 1 cm on the sand surface. 3. Cutting. The length of the cuttings can be about 8-15 cm, and the lower end can be flattened with a sharp knife (either horseshoe-shaped or flat), so that it is not perishable. The cuttings are inserted into the yellow sand about 1 stroke 3, and the green leaves below the surface of the water should be removed. Cuttings should not be too crowded, generally 1-3 plants are more suitable. 4. After planting, it can be placed in full sunshine environment (the cuttings in midsummer are better placed in the place of scattered light), but there can be no shortage of water on the sand surface. Please change the water once every 10 days and half a month to ensure the cleanliness of the water quality. It takes about 25 to 45 days to take root, when the sealed basin bottom hole can be poked open from the bottom and the water will be discharged. Wait for the basin soil to dry in a few days before watering, and enter the normal management stage. Note: a, to choose moisture-tolerant varieties, such as gardenia, Luohansong, June snow and other plants. B, the basin soil should be plain soil (without fertilizer). C, if it is not sure that the cuttings take root, the cuttings can be pulled out and observed. If a new white root appears on the callus, the water can be released and transferred to dry cultivation.

20. Water inserts Ruixiang.

Ruixiang is one of the best flowers, vibrant throughout the year, branches and leaves are green; when the flowers are in bloom, the fragrance is sent far away, full of spring, it is a precious flower during the Spring Festival. Among them, Phnom Penh Ruixiang, its leaves such as green inlaid with gold, the color first white to purple to red, very bright, very strong fragrance, color, fragrance, appearance, rhyme are all good, since ancient times as treasures. We want to breed Phnom Penh Daphne in our homes, and we generally like to use cuttings. This method is good, but the survival rate is not guaranteed, and the time is long. Comparatively speaking, water insertion is much better than soil insertion. Water insertion can be carried out from April to September, and now is the best time. Because when the temperature is low, it takes a long time to take root, even without rooting and rot; when the temperature is too high, a large number of bacteria breed in the water, which is not conducive to the rooting of branches. At present, the cutting temperature is suitable. The specific method is to cut off the branches of the current year, remove the lower leaves, leave 3-4 leaves in the upper part, and cut the socket into a horseshoe shape with a sharp knife to facilitate multiple roots. Then find a suitable bottle, fill it with water, and insert the lower part of the insert. It should be noted that the water bottle should be placed in a place with scattered light, not in the sun or too overcast. Change the water every three or four days. After the water is inserted, it can take root in about 25-30 days at the current temperature. For example, before water insertion, soaking cuttings with naphthalene acetic acid rooting solution for 4 hours can take root one week ahead of schedule. Description: 1. If there are more branches, you can tie it into a bunch and insert it. 2. When the root grows to 3-4 cm, it can be put on the basin. Be careful not to break the root. 3. After the cuttage is put into the pot in that year, there will be no new shoots in the same year, so there is no need to apply fertilizer. The seedlings will be able to blossom before and after the Spring Festival next year, and fertilize normally after flowering.

21. Soilless cutting-soft paper package

Teach you a simple and easy cutting method, no soil, no water, just a few pieces of paper. The specific operation methods are as follows: first, take a piece of soft paper with strong water absorption (toilet paper, etc.), first wrap the bottom of the cutter cut into a bevel, and the thickness of the soft paper is suitable to see the oblique surface of the incision after absorbing water, not too thick, so that the changes of wound healing and rooting can be directly observed, and it is very important to have good air permeability. Second, wrap the stem as much as possible with soft paper of the right size, but the leaves and bud eyes should be exposed. The thickness of the package is appropriate to ensure that the soft paper is not dry before the cuttings take root. Third, after wrapping, put the water-soaked cuttings in a container without bottom holes, fasten and moisturize the basin mouth with a thin film, and put it in a ventilated environment without direct light. in this way, your operation will be completed. after taking root, you only need to put on the basin. (note: after the cuttings are wrapped, the thickness of the stem is 2 times or slightly thicker, which can keep the soft paper from drying for a long time, and then there is no need for deliberate maintenance, and the cuttings can take root quickly. If you use this method to cut poinsettia, goose palm tea, peach leaf coral, etc., the fastest 7 days to take root, flower leaf goose palm tea 9 days, rubber trees have root tips in 10 days, and sturdy and developed. Peach leaves, corals and other roots take root a little slowly, but root tips form within half a month. This method is simple and easy, and a wide range of sources, low price, multi-layer container can be placed, saving space, one-time reproduction of a large number of flowers and trees, interested friends can have a try.

22, abuse method-- make your honeysuckle branches short and multiply

First of all, it is stated that this method is suitable for potted plants, not suitable for planting on the ground. What the land needs is to flourish and be able to afforest a large area of land in three dimensions. Potted plants have different requirements: the area is limited and cannot be allowed to develop; ornamental requirements are higher, and better shapes are required; the most important thing is that they should not bloom as casually as they are planted on the ground, but that they should concentrate and bloom luxuriantly. The following methods can help you do this:

First, buckle water ~ Honeysuckle is a vine, without interference, its branches grow fast and long. In the basin, we can break the convention by not watering it in the evening and watering it in the morning when it sprouts in spring, and watering small water instead of heavy water, so that its physiological water can not meet the needs of prosperous growth, shortening and aging new branches. When the branches are old, they are easy to blossom, while shortening narrows the distance between the internodes, and the blossoms are concentrated and flourish.

Second, fertilizer restriction ~ before the formation of flower buds, there is no or as little nitrogen fertilizer as possible, but relatively more phosphorus and potassium fertilizer. When the flower bud is basically formed, the striping is basically over, and then appropriate amount of nitrogen fertilizer is applied to make it form a situation of multi-flower and large flower.

Third, turn the basin lazily ~ that is, turn the basin only once in 3-4 years. The purpose is not to let it sprout more new roots, the new roots are less, the absorptive capacity is poor, coupled with the basin soil aging, it is very difficult to grow, so as to achieve the purpose of controlling the tree potential, limiting branches, and blooming densely.

Fourth, pruning ~ pruning strong buds, pruning long branches, cutting length and leaving short. Then put it in a sunny place (half-cloudy and half-sunny in summer) to prevent it from growing because of insufficient light.

Through the above measures, you can make your honeysuckle shorter and more ornamental. The seedling is not in this case because it is allowed to flourish so that it can blossom as soon as possible. This method also applies to June snow.

23, Milan, blooming every day and fragrant every day

Milan, the leaves are shiny and evergreen all the year round. When the flowers are in bloom, they are fragrant and fragrant, and the golden flowers like rice grains are also eye-catching against the green leaves. If the maintenance is in place, it will not be a problem for Milan to blossom five times a year, then can it blossom every day? There's a way--

Generally speaking, after Milan blossoms once, it has to "rest" for a period of time before it can blossom again, that is, it has to accumulate nutrients to prepare for the next flowering. So it blossoms intermittently. We want her to bloom every day to artificially meet its nutrient needs, that is, through proper bud thinning to reduce the nutrients consumed by each flowering. Specifically, when Milan blossoms for the first (or second) time in spring, it can first remove the buds of 1-2 branches, and then remove the buds of 1-2 branches after 4-5 days, so that it can be carried out again and again, accumulatively more than 6-7 times, and the branches after thinning can reach more than 60-70% of all branches. In this way, all branches of Milan can bloom in turn. It has achieved the goal of blooming and fragrant every day. According to the procedure, the unthinned branches blossom first, and after about 5-10 days, the branches that sparse the buds for the first time bloom, and then bloom according to the order of the flowers. In total, a pot of Milan will allow you to smell incense every day for 7-8 months throughout the growing season. (because it has a strong fragrance, it might as well remove some.)

Main points: 1. Keep up with water, fertilizer and light.

2. The plant should not be too small, it should have at least 10 branches.

24. Beer spray and kill two birds with one stone

It is self-evident that flower growers like to deal with all kinds of flowers. But you are dealing with not only flowers, but also all kinds of pests, , even though you don't like it at all.

Among the pests, aphids and red spiders are fairly easy to deal with, the symptomatic medicine is sprayed twice, the basic ok. But the shell bug is more troublesome, he has a protective layer-wax shell, spray has little effect on it, it really has some bulletproof meaning. So, in addition to manual deworming (brush brush), is there a more simple and effective way? Yes. When you find a shell bug, don't panic. Prepare a bottle of beer, pour out some mixed with water, proportion water 6 wine 1, spray the plant again, spray all parts as far as possible. Check it carefully the next day. If the bug turns reddish brown and falls off as soon as you touch it, it must have come to an end. If there's anything alive, spray it again. Generally, after spraying three times (three days), it can be solved basically. Principle: after the beer is sprayed, a sealing membrane is formed on the worm, suffocating it to death. However, it is also possible to die of drunkenness, which, of course, needs to be proved by entomologists. In addition, beer is still a good leaf fertilizer, often sprayed, and the plant can grow with vitality and spirit. The proportion is lighter than that of pest control, water 8 and wine 1 can be used. If you want to, you might as well try.

25. Four methods of water supply

Watering is the first hurdle for flower growers to go through, and it is also a must. Despite the simple watering, there are actually a lot of exquisite flowers in it, and many novice flowers are turned off on watering. With regard to watering, the so-called dry and wet; more watering in the growing period, less watering in the dormant period, more watering in small pots, less watering in large pots, and so on, we all know better, so I won't say much about it. Here are only a few special water supply methods--

1. Sand column method-preventing basin soil consolidation

In the flower pot or turn over the basin, first set up a few hollow pipes in the basin (bamboo tube, plastic pipe and iron pipe, etc.), and then fill the soil around it. Then pour the coarse sand into the pipe, and the upper end is flush with the soil surface. Finally, the empty tube is gently pulled out, and a sand column is formed in the basin. In the future, when watering, the water only spreads around through the sand column, which prevents the soil from hardening and has no adverse side effects.

Note: the pipe should not stand in the center, but leave the place where the flowers are planted.

2. Itinerant method-without pouring half of the water

Half of the water is watered, that is, the water is not thoroughly watered, the top is very wet, and the bottom is still dry. If this is often the case, flowers and trees are still immortal? There are several reasons: inexperience; basin soil is too rigid; did not turn the basin for a long time, root disk entanglement, and so on. The solution is as follows: if you have more flowers, you can water them one by one, regardless of whether they are thoroughly watered or not. After all the water has been poured, it can be watered again from beginning to end, and some of them can even be watered for the third time. In this way, half-cut water can be put an end to. Because after the first round of watering, even if it is not watered thoroughly, the basin soil has been moist and softened to a certain extent, so that after a period of time, the second round of water is easier to be absorbed.

Note: there is no need for loose basin soil. If there are not many flowers, you can do something else after watering and water them again later.

3. The method of sitting in the basin-preventing the rotting roots of the broom.

The broom is very beautiful, it looks like a butterfly when it blooms, it looks like a flying canary when it unfolds, and it can make bonsai, so many people like to keep it. But in recent years, there are fewer and fewer people, because it is very easy to rot roots, and it will die if it is not careful. There is one method that is very effective in preventing its rotting roots, that is, sitting in the basin. Put some water in a container, plant the broom pot in it, wait until the soil is wet, that is, it has been thoroughly watered, then you can take it out.

Note: the principle of seeing dry and wet should also be followed.

4. Noon water-make jasmine more fragrant

Watering jasmine at noon can make jasmine blossom more fragrant to the nostrils, the ancients have summed up: "to get jasmine, a ladle of soup at noon." But watering under the sun at noon is a taboo for growing flowers, just like when people are too hot to take a shower immediately. To water flowers at noon without an accident, the premise is to put the water in the sun, wait until the water temperature is close to the soil temperature before watering, so ok, insurance.

Reminder: other plants have not been tested, please use with caution.

26, the old towel gourd helps you with beautiful leaves and green flowers

The vines of towel gourd gradually withered like an old man's arm, the leaves trembled in the wind, and only one old towel gourd still hung heavily.

In the past, villagers used it to wash bowls and pots, but now no one uses it, and it seems to be a waste. Is it really useless? No! Take off the old towel gourd and wash it to dry. When the flowers are turned over to change the soil or on the basin, cut them into small pieces of about 5 centimeters. Spread a layer of towel gourd stem in one place of the basin bottom soil, fill it with soil, then spread another layer in the basin soil, add more soil, and then you can exercise normally.

Note: before cutting, lay it flat on the ground and smash the loofah seeds with a hammer.

This method can effectively improve the basin soil and make it loose and unconsolidated. And loofah tendons and seeds decompose slowly in the potted soil, which is a good long-term nitrogen fertilizer, so the potted flowers are all leaves and green flowers.

A complete Collection of Flower Conservation techniques

To raise potted flowers well, mainly in maintenance and management, should be in line with the habits of flower growth. Novice flower growers either apply too much fertilizer, "burn" the seedlings, or overwater the plants and "drown" the plants. Especially in watering, regardless of the season, climate, basin soil dry and wet and growth stage and other specific conditions flexibly grasp, but must be watered every day, watering a lot, so that the plants are killed. For beginners, wet-loving flowers should be chosen for the first time, such as water bamboo, bamboo evergreen, tortoise-backed bamboo and ferns, which will not be watered to death. Secondly, annual grass flowers can be planted, such as zinnia, impatiens, a bunch of red, half lotus, Cuiju, ornamental chili, etc., these grass flowers are not easy to be watered to death. Of course, these kinds of seedlings may also be watered to death, but it is not a pity that they are just grass flower seedlings, from which experiences and lessons can be summed up. For novice flower growers, because they are not used to it or don't remember, sometimes they forget to water it in summer, which often affects the growth of plants or dies because of drought. To this end, in addition to planting wet flowers, you can also plant some flower species that are both moisture-tolerant and drought-tolerant, such as oleander, Luohansong, silk cotton wood, canna and so on. After having a little experience, we will plant flowers that are easy to grow and easy to manage, such as purple duckweed, winter coral, night cloves, orchid, pomegranate, spring, geranium, four seasons begonia and so on. Only when we have some experience can we cultivate advanced flowers.

13 ways to prolong the life of bottle flower

1. The best time to pick flowers is when the dew is not dry in the morning. After cutting off the flower branches, it is appropriate to soak in warm water immediately to stimulate the fiber tube to open and fully absorb water so as not to dry up.

two。 Cutting flower branches should be carried out in water, which can prevent air from entering the water absorption pores of human branches and affect the effect of water absorption.

3. Cut the flower branches, the more oblique the incision, the better. Thick woody plants such as black pine and rhododendron can also cut the epidermis of about 3 cm at the cut and crack it slightly with a hammer to enhance its water absorption function.

Chrysanthemum, Christmas flowers, orchids and other strong water absorption flowers, flower branches can be longer, weak water absorption flower branches should be short, the closer to the water, the better.

4. Cut off the epidermis of the stem end of the flowers in the vase by about 6mm and apply Vaseline to prolong the flowering period.

5. The cut of the woody flower stem can be burned for several minutes, or put some salt on the cut to prevent the incision from rotting prematurely.

6. If the stem end of the flower branch is soaked in vinegar for a while and then inserted into the bottle, the flowering period can be prolonged. Adding a few drops of vinegar to the vase can make the flowers absorb water easily and keep them alive for a long time. Vinegar also has a germicidal effect.

7. Put an aspirin tablet in the bottle to prolong the life of the flower.

8. Flowers with large ridges and fine flowers are bundled into bundles with waste short branches and then placed in bottles.

9. After the flowers are placed in a bottle, if they are exposed to low light for 1 hour in the morning, it will help to keep the flowers bright.

⑪ should change water frequently, preferably once a day. The water should be changed at night. If you move the vase to an outdoor cool place to absorb dew every night, you can see that the vase will restore its original bright color the next morning.

⑫ if you put some ice in the vase in the middle of summer, you can keep the leaves on the flower branches green.

When changing water in ⑬, the adhesives on the cut of flower branches should be removed.

6 methods of watering flowers and plants

When watering potted flowers, you should master "do not dry, do not water, water as soon as you dry." The principle of "if you don't water it, you water it thoroughly". The specific trick of watering is:

1 ordinary watering method

Water directly from top to bottom (soil) from the basin. This method is simple and easy. However, the disadvantage is that it is easy to make the lower basin soil dry for a long time and cause soil consolidation, which is disadvantageous to the development of the root system, so when using this method, it is necessary to make sure that the water overflows from the drain hole at the bottom of the plate.

two。 Pelvic floor suction method

Put the flowerpot in another large container containing clear water so that the water is wet from the bottom to the surface. The advantage of this method is that it can absorb large water surface, prevent soil consolidation and promote root development, especially for deep-rooted flowers. The disadvantage is that the salt in the basin soil will rise with the water and accumulate on the basin surface and basin edge, causing ugly salt spots. The above two basic watering methods should be used alternately, learn from each other, and the effect is better.

3. Pipe drip irrigation method

Pull the plastic pipe apart and place it around each pot plant that needs to be watered. It is appropriate to be close to the stem of the plant, and then needle one or two small holes in the plastic pipe. The two ends of the pipe are closed. After connecting the water source, the water drips slowly from the small hole to supply the plant water.

4. Rope suction pouring method

When going up or changing the basin, bury a fiberglass rope at the bottom of the flowerpot. One end of the rope is laid flat on the bottom of the basin, and the other end extends from the drain hole. The bottom of the basin is padded with a water tray, and the end of the rope is immersed in water. When the basin soil is dry, as long as the water is injected into the water tray, the water will be automatically carried into the basin with a rope.

5. Sand column watering method

When potting or changing the flowerpot, first erect several hollow tubes in the empty pot, which can be bamboo tubes, glass tubes or metal tubes, then fill the tubes with coarse sand, then pull out the empty tubes, and sand columns are formed in the basin soil. The diameter of the sand column depends on the size of the basin. In the future, it is only necessary to water the sand column to make the water spread evenly to the surrounding basin soil through the sand column, which can avoid soil consolidation and is beneficial to the growth of branches and plants.

6. No-one watering method at home

People who love to grow flowers, because they go out to visit or do business for ten and a half days, no one is at home to water the flowers. At this time, you can fill a plastic bag with water, stab a hole in the bottom of the bag with a needle, and put it in a flowerpot. The small hole is attached to the soil, and the water will slowly ooze out to moisten the soil. The size of the hole should be properly controlled to avoid water leakage too quickly. Or put a vessel filled with cold water next to the flowerpot, find a wide cloth strip with good water absorption, put it in the water at one end and bury it in the pot soil at the other end. In this way, the soil can remain moist for at least half a month or so, and the flowers will not die.

Skillfully use five kinds of water to water flowers

1 residual tea watering flowers

Residual tea is used to water flowers, which can not only maintain soil moisture, but also add nitrogen and other nutrients to plants. However, according to the humidity of the flowerpot, it should be watered regularly and appropriately, not along with the residual tea.

2. Water the flowers with spoiled milk

After the milk has gone bad, water is added to water the flowers, which is beneficial to the growth of flowers and trees. But there should be more water, so it is better to make it scarce. Unfermented milk is not suitable for watering flowers because it produces a lot of heat during fermentation and will "burn" roots (rotten roots).

3. Water the flowers with cold boiled water

Watering the flowers with cold boiled water can make the flowers and trees luxuriant and colorful, and promote their early flowering. If it is used to water asparagus, it can make its branches and leaves develop horizontally, short and dense.

4. Water the flowers with water.

When the weather is cold and the water is cool in winter, it is appropriate to water the flowers with warm water. It is best to put the water indoors and water it when it is close to room temperature. It would be better to water the water when the temperature reaches 35 degrees Celsius.

5. Wash rice and water the flowers

Often use Amoy rice water to water Milan and other flowers, can make its branches and leaves luxuriant, flowers and colors bright.

Grow flowers with beer

1. Flower arrangement: when arranging flowers, as long as a little beer is poured into the vase, the color and fragrance of the arrangement can be prolonged by 15 to 20 days than usual.

two。 Potted flowers:

(1) wipe leaves with beer: where foliage flowers, skimmed cotton or clean soft cloth can be dipped in beer and gently wipe leaves. It can not only remove dust and sterilize, but also play the role of foliar fertilization, which can make the leaves greener and brighter, and the texture of the leaves is also thicker.

(2) spraying leaves with beer: after mixing water and beer at 1:1, spraying small leaves such as asparagus, hanging orchid, umbrella bamboo, begonia and geranium with a fine-eyed spray can get the same good effect of wiping leaves with beer.

(3) use beer to water flowers. Beer is an excellent aromatic fertilizer. Watering flowers with beer not only has good nutrition, but also absorbs nutrients quickly.

Sponge regulates the moisture of potted flowers and plants

Cut the sponge to the same size as the flowerpot and put it on the bottom of the mud when planting flowers, which is of great benefit to your flowers and plants, because it will absorb the excess water in the pot; when the soil is dry, the soil itself will absorb the water in the sponge.

Notes on growing flowers and changing pots

The old flowerpot due to long-term watering, fertilization, the tiny stomata on the pot wall are closed, flowers can not get fresh air, will die because of poor growth. Therefore, most potted flowers and trees need to change pots once a year, while bamboo and fir, which need more nutrients, need to change pots twice a year. Generally speaking, most deciduous tree species change their pots in early spring; evergreen species, such as June snow, tiger thorn, gazelle, etc., should change pots in summer; Luohan pine, cypress. Any season except in the depths of winter. Bamboos that change pots twice a year are usually in May and September, while Cunninghamia lanceolata should be in March and October. When changing the basin, you should first gently lift the plant from the basin, remove half of the old soil, cut off the rotten roots and overlong roots, put the plant back into the basin, and then fill the newly prepared soil with proper watering. It should be noted that the drainage hole at the bottom of the basin should be clasped with tiles before the plant basin, and be properly bottomed with gravel.

Two methods of soil disinfection in spring

Many diseases, such as anthracnose, black spot, brown spot, gray mold, blight and so on, overwintered in the soil as mycelia or sclerotia. Methods of soil disinfection:

1. Medicament disinfection

Formaldehyde and pentachloronitrobenzene can be used to kill bacteria. Formaldehyde, also known as formalin, has strong bactericidal power. At the same time, every 50 grams of water 2-2.5 kg, can be sprayed 15-20 cm thick soil 1 square meter. Spray evenly. After spraying, cover strictly with plastic sheet, fumigate for four or five days, then remove the plastic sheet, turn the soil, make it dispel the smell of medicine, and flowers can be planted after 15 days. Dibromine and chloropropane should be used to kill nematodes. When in use, burn 10 grams of oil with 80% dibromopropyl per square meter, 3 kg of water, spray it evenly on the soil and cover it with plastic sheeting immediately. Remove the plastic sheet and turn over the soil after six or seven days. It takes about 15 days to grow flowers.

two。 High temperature extinction

The easiest methods are burning and stir-frying. The method of burning soil is to spread the soil flat on the ground, with a thickness of about 30 centimeters, and stack firewood and grass on it for more than 20 minutes. The method of stir-frying is to stir-fry the soil in a broken iron pan, keeping the temperature above 90 degrees Celsius and stir-frying for 20-30 minutes.

Different balcony positions are suitable for planting flower species.

The balcony in the south and southwest has long light time and high temperature, so it is suitable to put flowers and trees that like sunshine and heat resistance, such as jasmine, Michelia, pine, cypress, cactus, etc.; orchids, camellias, rhododendrons, roses, orchids and other good shade or fear of heat, should be moved to the north or east balcony to avoid excessive sun exposure.

Summer care of orchid, Gaoyu plum, rose, Milan and cactus plants

1. Orchid

Summer is the peak growing season of orchids, so it is necessary to ensure the water and nutrients needed for growth.

two。 High temperature plum

Anthrax is easy to occur. In addition to improving ventilation and light transmission, topiramate can be sprayed once every 10 days when the disease occurs.

3. Rose

Like fertilizer and water, it is necessary to ensure an adequate supply of water and fertilizer. Apply rotten bean cake water or fish fertilizer water once every half month. Fertilization will be stopped in mid-July. Powdery mildew is easy to occur in summer. Spray with Bordeaux solution or carbendazim once a month for 2 ~ 3 times.

4 Milan

I like light and heat. It grows vigorously in summer. Before and after flowering, thin water was applied every 10 days. Stop fertilizing when the temperature exceeds 30 degrees Celsius. To ensure the supply of water, often spray water to the leaves to prevent falling flowers and buds.

5 cacti

Although drought tolerance is extremely strong, there is still a risk of burns when the temperature exceeds 38 degrees Celsius. Do not apply fertilizer and spray water to cool down in high temperature season.

Key points of fertilization for potted flowers in autumn

Most potted flowers are in a vigorous period in autumn, so the nutrients needed for potted flowers must be guaranteed to meet the growth needs. Topdressing should be treated differently according to the growth status of potted flowers. Under normal circumstances, the mature rarefied liquid fertilizer is applied every 10 days. For potted flowers that bloom in autumn, such as sweet-scented osmanthus, chrysanthemum and dahlia, we should apply less nitrogen fertilizer and more potassium fertilizer to promote them to blossom and flourish.

Key points of pruning potted flowers in autumn

There are many buds of potted flowers born in autumn, which can not be allowed to develop completely. Except for some of them to be retained, all the others should be picked to avoid wasting nutrients. When pruning, the retained branches should be treated with leaves and buds. The plants with strong growth should be cut heavily, and those with weak growth should be cut lightly. For potted flowers with buds in summer and autumn, such as plum blossom, wax plum, rhododendron, etc., in order to protect the formed branches, it is not suitable for re-pruning, pruning can be carried out.

Foliage plants survive the winter skillfully indoors

Foliage plants are mostly found in tropical and subtropical regions, and their growth temperature should be kept at 25 ~ 30 degrees Celsius. In areas with obvious changes in the four seasons, plants often freeze to death or wither because of low temperatures in cold seasons. Therefore, in order for foliage plants to survive the winter smoothly in these areas, attention should be paid to:

1. Cultivate adaptability

If you put it indoors, let foliage plants come into full contact with the low temperature climate in early autumn, in order to enhance the cold resistance, you can gradually adapt to the low temperature environment. Therefore, from early autumn to late autumn, plants should be fully exposed to the decreasing temperature.

two。 Water quantity

As the temperature drops, plants grow slowly and almost stop growing in the cold season. At this time, the watering times of basin soil should be reduced. The standard of watering in winter is that the surface of basin soil is dried for 2 ~ 3 days and then watered again. But in a room that has heating and can maintain a certain temperature, you should still pay attention to watering at all times.

3. Indoor humidity and temperature

When winter comes, foliage plants that move indoors, especially those in heated rooms, should often be sprayed with foggy water to improve air humidity. The temperature difference between day and night in the room should be as small as possible, the lowest indoor temperature at dawn should not be less than 5 ~ 8 degrees Celsius, and it should reach 1-20 degrees Celsius during the day. If you can meet the above requirements, you can generally survive the winter smoothly. In addition, in the same room, there will also be a temperature difference between the upper and lower spaces of the house, so plants with weak cold resistance can be placed on bookshelves and other places. Foliage plants placed on the windowsill are most vulnerable to cold wind, so it is appropriate to use thick curtains.

4. Light

The sun shines obliquely in winter, and the light intensity is half that in summer. Some sunny foliage plants should be placed near the sunny south window. Ornamental plants that have been placed indoors and in the shade for too long should not be suddenly placed in outdoor direct light so as not to cause leaf burns.
