How to water the pineapple flower, the winter watering method of the pineapple flower / water and fertilizer had better be watered together.

In the cultivation of flowers, watering is a link that can not be ignored. Once something goes wrong, it will cause all kinds of problems, which can be said to be troublesome. Among them, special attention should be paid to watering the pineapple, because its roots cannot absorb water, and all nutrients and water are absorbed by the leaves, so how can the pineapple be watered? The following is the method of watering pineapple in summer and winter. If you love flowers, you must have a look.

First, how to water the pineapple flowers and water the pot soil as soon as it dries.

In the pineapple culture methods and matters needing attention, we have introduced that watering is very important for pineapple. But the pineapple flower absorbs water by the leaves, not the roots, and all watering can be neither more nor less. The best watering method is: the basin soil surface is slightly dry, it is necessary to start watering, but not too wet, too wet is easy to soak the root.

Can the leaves of pineapple be watered?

Other flowers absorb water from the root, from the bottom up, but the pineapple is an exception, because its roots can not absorb water, nutrients and water are absorbed through the leaves. Can all the leaves of pineapple be watered? I'm sure they can. The reason for this is that pineapple is originally grown in hot and humid regions of South America and is a wild plant attached to branches and branches.

Reasons for watering pineapple leaves

Because it is attached to the branches and branches, the pineapple does not touch the soil, and its roots naturally cannot absorb water from the soil. What should I do at this time? In order to survive, pineapple has evolved a function that relies on leaf cups and other mesophyll tissue to absorb water and nutrients.

In modern times, pineapple is gradually planted artificially, but compared with other flowers, its roots are still frighteningly fragile. When we breed pineapple, we can hardly see the roots, only the black soil. In addition, the root of pineapple is also black and very thin, so its nutrients and water are absorbed by leaves, which is the reason why pineapple leaves are watered.

Second, the watering method of pineapple in winter

In the spring and autumn, the temperature is not high or low, just water the pineapple properly, what we should pay attention to is watering in winter. As for how to water the pineapple in winter, the flowers only need to be watered in the leaf tube, usually once every 8-9 days. Note that the water in the blade tube should not exceed a week, otherwise it will not be fresh, and the stale water will carry germs.

Note: when blooming, do not irrigate in the pineapple leaf tube, store in a place away from the sun, it can prolong the flowering period. After entering the dormant period, the pedicel must be cut off to reduce the consumption of nutrients. Don't fill the tube with water in winter.

Third, how to apply fertilizer to pineapple

Water is absorbed by leaves and nutrients are also absorbed by leaves, so if you apply fertilizer to pineapples, you have to dilute the fertilizer and pour it into a leaf cup, so that beautiful flowers can bloom. It should be noted that not too much watering, or it is easy to rot roots.

During the growing period from the end of spring to autumn, the amount of water can be increased appropriately, and some water can also be irrigated in the leaf tube, and the water can be changed once a month. At this time, it can also be watered and fertilized together, so that the pineapple flowers can bloom beautifully. This is the editor's introduction on how to water the pineapple flowers. I hope I can give you some help.

How to water the pineapple: when watering, the basin soil of the pineapple family should be slightly dry, that is, the surface of the soil should be 1 to 2 centimeters dry, and then water the second time, it is not too wet, it is easy to soak the root too wet. The root is tender. The root of the pineapple family has a leaf tube at the root of the leaf, and the leaf tube has a sink. Make sure that there is always water in the tank, which cannot be cut off. After a period of time, for example, about ten days, you have to replace it, lest the water stinks, and you can usually spray some foggy water on the surface, leaves, and flowers. Its leaves are staggered and superimposed, one by one, and there is no gap at the bottom, so the water can not leak out when pouring, and it can hold the water in its pocket. Because its nutrients and water are absorbed by this mesophyll tissue, other flowers are absorbed from the bottom up by the roots. Plants absorb water and nutrients through roots, which everyone knows, of course, including all kinds of flowers, how to say that pineapple is an exception? It turns out that pineapple is originally grown in hot and humid regions of South America and is a wild plant attached to branches and branches. Because it is attached to branches and branches and does not touch the soil, its roots cannot absorb water and nutrients from the soil at all, so it must find a suitable way to complete the continuation of its own life. so it relies on its own unique nutritional organs-leaf cups and other mesophyll tissues to absorb water and nutrients. Pineapple root, which has lost its original function, is still useful. since pineapple is an epiphyte, it must have an attached bond. Wild pineapple root plays this role, and it firmly fastens itself to the epiphyte with its root. Up to now, although pineapple has been artificially planted, compared with other flowers, its roots are so rare and weak that they can hardly be seen. They are all black soil. Their roots are black and very thin, so they can hardly be seen, so their nutrients and water are absorbed by leaves. Water is absorbed by leaves and nutrients are also absorbed by leaves, so if you fertilize the pineapple, you naturally have to dilute the fertilizer and pour it into the leaf cup, otherwise your pineapple will never grow up, let alone a beautiful spike. Pineapple directly into the leaf cup watering fertilizer, watered too much, it is easy to rot roots, generally watered between the leaves, should not leak, look almost full, quickly stop, no more watering. Do not use tap water to irrigate, you have to use deionized water, otherwise the sodium ion and chloride ion content in the water is too high, a large amount of salt will be accumulated in the soil, over time, the roots of pineapples will rot, and the flowers will not only have small ears and light colors, but also a large number of deformed flowers. Pineapple flower has always been regarded as a symbol of auspiciousness and prosperity because of its beautiful and changeable flower shape and long viewing period. How, understand the pineapple conservation methods, do you also want to buy a pot at home, to add a festive atmosphere? The maintenance of ornamental wind pears is extremely easy, as long as they like the habit of high temperature, moisture and semi-shade, they can be placed in a warm and bright room all the year round. There should be full sunshine in winter, morning and evening in spring and autumn, and no direct sunlight in summer. The light is bright and the leaves are brightly colored. The overwintering temperature should be no less than 10 ℃ and higher than 20 ℃, which is not conducive to plant dormancy and will affect the growth and sweat flowers in the coming year. During the growing period from late spring to autumn, you can appropriately increase the amount of water, and you can also irrigate some clear water in the leaf tube. You should change the water once a month to prevent the water from deteriorating and smelly. Often spray foliar water. It is appropriate to dry some on the basin in winter, but not too much. From May to September, nitrogen fertilizer should be applied once a week, and phosphorus and potassium fertilizer should be applied appropriately before flowering to promote the flower to be bright and colorful. When flowering, do not irrigate in the tube, store in a place away from the sun, can prolong the flowering period. After entering the dormant period, the pedicel must be cut off to reduce the consumption of nutrients. Don't fill the tube with water in winter. The root system of ornamental pineapple is not very developed, there are no main roots, and some roots like to come into contact with the air, so planting in small and shallow pots will grow and develop better than those in large and deep pots. It is best to add a small amount of garden soil to rotten leaves, or mix peat and perlite in half. After flowering, the central leaf cluster dies and the collateral daughter plants continue to grow. When the daughter plant is 15 cm high, it can be removed from the mother plant and replanted with roots. In doing so, it can only be passed on from generation to generation, and the number of reproduction is limited. Therefore, it is best to change the basin in spring, cut the small tuber cuttings that grow from the tuber part of the mother plant, or the young buds sprouting from the roots of the old plant, all should avoid shade, moisturize and keep warm, and when the root system grows to 2Mul 3cm, it can be planted. If cultivated properly, a mother bead can reproduce about 10 plants a year. In daily management and protection, pineapple plants should be placed in a semi-overcast ventilated place and nurtured with scattered light. Strong light is easy to burn the leaves and show miscellaneous spots, but be careful not to put them in the shade for a long time, because the beautiful color of the leaves often becomes lighter and lighter, resulting in ornamental regret. In the case of dry climate, muggy heat and low humidity, the leaf edge and leaf tip of pineapple are easy to scorch, so to keep the basin soil moist, you can spray water to the leaves once or twice a day, and the cup-shaped part of the leaf seat can be filled with water. Pineapple plants were originally parasitic plants, the root system is not developed enough, only small and short roots, so do not apply too much fertilizer, to prevent root rot, leaves yellowing, should be applied with thin fertilizer and water. The ornamental pineapple is an ornamental plant of the pineapple family, with beautiful plant shape, bright leaves and spikes, peculiar flower shape and a flowering period of up to 2 mi for 6 months. it is a new generation of indoor potted flowers. 1. Propagation methods: small-scale production and family cultivation of ornamental pineapple, generally using tiller bud cutting. There are several tillering buds in the axils of the basal leaves of the ornamental pineapple before and after flowering. When the tillering buds grow to about 10 cm and there are 5 leaves, cut off the short stems close to the mother plant with a sharp knife, disinfect the wounds with fungicides, dry them slightly, dip them in Cai acetic acid with a concentration of 300rel 500 mg / kg, cut them in perlite, coarse sand or culture soil, keep the substrate and air moist, and give proper shade. After 1 month, new roots grow. Can be transferred to normal management. Attention should be paid to the fact that the cuttings are not easy to take root when the tillering bud is too small, and the propagation coefficient is low. Second, cultivation and management 1. Cultivation substrate: most of the ornamental pineapple cultivated in production are epiphytic species, which require loose substrate, air permeability, good drainage and acidic or slightly acidic ph. In production, materials with good permeability should be selected, such as bark, pine needle, ceramsite, grain husk, vinegar sugar, perlite, etc., and mixed with rotten leaf soil or cow dung, such as 3 pine needles, 1 peat plus 1 cow dung, or 3 peat plus 1 sand plus 1 perlite, etc. two。 Fertilizer and water management: epiphytic ornamental pineapple has a weak root system, which mainly plays the role of fixed plant, and the absorption function is secondary. The water and nutrients needed for its growth and development are mainly stored in the grooves formed by the clasping of the leaf base and absorbed by the absorbing scales at the base of the leaf. Even if the root system is damaged or rootless, as long as there is a certain amount of water and nutrients in the groove, the plant can grow normally. In the summer and autumn growing season, 1 Mel sprinkled water into the grooves once in 3 days, and foliar spray 1 Mel 2 times a day. Keep water in the grooves, the leaves are moist and the soil is slightly dry; spray less water in winter to keep the pots moist and the leaves dry. Ornamental pineapple is sensitive to phosphate fertilizer. When applying fertilizer, nitrogen fertilizer and potassium fertilizer should be used mainly. The ratio of nitrogen, phosphorus and potassium should be 10 ∶ 5 ∶ 20. The concentration is 0.1%. Complete chemical fertilizer such as 0.2% urea or potassium nitrate is used. Thin alum fertilizer water can also be used in production (clean water is needed to wash the leaf center before leaving the nursery), foliar spraying or application into grooves, spraying once every two weeks in the peak growing season. In winter, 3mer is sprayed once a week every 4 weeks. 3. Environmental control: the optimum temperature of ornamental pineapple is 15 ℃ 20 ℃, the winter temperature is not less than 10 mol, and the humidity should be kept above 70%. In the north of China, the summer is hot, the winter is cold, and the air is dry. In order to make it grow normally, it is necessary to manually control the microenvironment of its growth. Shading and transpiration can be used in summer to keep the ambient temperature below 30 ℃. In May, a sunshade net with a light transmittance of 50-70% was added at 20ml 30 cm above the greenhouse film to cool down and prevent pineapple leaves from burning. When the temperature is high around noon in summer, spray water to the leaves with micro-nozzles, according to the air temperature and light, generally spray for 10 minutes every 2 hours, keep the leaves and the environment moist, increase ventilation, reduce leaf temperature through water evaporation, and increase air humidity at the same time. Covered with double-layer film in winter, and equipped with heating equipment such as heating and hot air stove to maintain the indoor temperature above 10 ℃, pineapple can survive the winter safely. 4. Florescence control: the natural flowering period of ornamental pineapple is mainly in late spring and early summer. In order to make pineapple blossom in New Year's Day Spring Festival, the florescence can be controlled manually. Fill the pineapple grooves with 100 mg / kg ethephon solution with a concentration of 50 Mel. Pour it out after 7 days, change the clean water and pour it into the groove, and the flower can blossom in 4 months after treatment. Pineapple maintenance is relatively simple. The key is the method of watering, not only the pot soil, but mainly in the leaf cup, that is, the depression in the middle of the flowers and leaves! Pineapples are generally in the flowering stage at home, so generally do not need to apply too much fertilizer, or do not need to apply fertilizer at all, especially some pineapples produced professionally in the greenhouse, their fertilizers can far meet the needs of flowering. When there is heating or air conditioning at home, you should frequently spray warm water to the whole plant to humidify, if possible, you can turn on the humidifier! The storage environment needs scattered light, do not put it in too shaded place, even if there is enough light in winter, other seasons need proper shade! The pineapple in the home does not need to be thrown away immediately. When the lower seedling grows to about 20 cm, it can be separated from the mother plant and cultivated in another pot. When the leaves grow to stretch and fullness, you can urge the flower (with ethylene or acetylene solution). Fertilization should be applied frequently and less, to ensure that there is water in the leaf cup, not dry on the line! The suitable temperature for growth is between 15 and 28 ℃. Pineapple is an indoor ornamental flower in winter and spring, evergreen in four seasons, beautiful and colorful inflorescences, such as bright red, pink, golden yellow, rose and so on. Pineapple has a long flowering period and is suitable for family cultivation. The winter management of pineapple should pay attention to the following points: 1. The suitable temperature is 15 ℃ to 22 ℃, and the lowest temperature in winter should not be lower than 10 ℃, otherwise the plant will suffer frost damage, make the leaf color turn yellow, and affect the healthy growth of the plant. 2. in order to make the pineapple leaves bright and blossom regularly, light is very important. In winter, there should be at least 4 to 5 hours of direct sunlight every day. In case of cloudy and rainy days, lights can be used to increase the light. In summer, the seedling pot should be placed in the shade, and indoor cultivation can also shade the net as needed. 3. Pineapple is suitable for the growth of loose, fertile and humus soil. In family cultivation, peat soil can be mixed with 2 parts of peat soil and 1 part of fine sand to prepare culture soil. Pineapples bloom in winter and require adequate fertilizer. Thin organic liquid fertilizers such as bean cakes and sesame sauce dregs are usually used every two weeks (with a concentration of 20%), or soy beans or fermented rice panning water can be used. 4. Pineapple is fond of humid environment, keep the basin soil moist on weekdays, and generally do not water on rainy days. Family farming, it is best to use dried water, not directly irrigated with tap water. Pineapple is a flower that can enjoy both flowers and leaves. It is best to spray water on the leaves once a day to remove dust and make the leaves bright. At the same time, it is also conducive to photosynthesis and promote the healthy growth of plants. 5. Pest control: pineapple flowers are prone to diseases and insect pests in the environment of high temperature, humidity and poor ventilation, such as soot, powdery mildew, red spiders, shell insects and so on. If diseases are found, carbendazim can be sprayed in time, and pests can be sprayed with omethoate. No matter what kind of solution is sprayed, sterilization and insecticidal tablets must be purchased in the outdoor flower market and buried in the basin soil to eradicate diseases and insect pests. To prevent pollution of the indoor environment In addition, you can also buy sterilization and insecticidal tablets in the flower market and bury them in the basin soil to eradicate diseases and insect pests. Pineapple watering only needs to fill the leaf tube every two or three days, and fertilization is also to pour water and fertilizer into the leaf tube. Tips: pineapple habits like semi-overcast, should prevent the hot sun exposure, placed in semi-shaded or bright windows, indoor. The pineapple suits its temperature. If the winter is not less than 15 degrees, there should be no problem, like the general home heating, there should be no problem. In fact, with these points in mind, it is much easier to preserve pineapples, but I would like to remind you that the biggest weakness of pineapples is not afraid of cold, but fear of flooding, so there is a lot of knowledge in watering.

What about the insects growing in the pineapple flower? pest control of the pineapple flower / 3 insect pests and 3 diseases

The beauty of pineapple is reflected in the flower. After all, it only blossoms once a year. But because some flower friends maintain improperly, pineapple flowers will be infested by insects, resulting in a decline in ornamental, then how to grow bugs in pineapple flowers? In fact, there is no need to panic, we just need to find out what kind of pest it is, and then solve the problem. The following are the common pest control of pineapple, let's go and have a look.

What about the worms growing in the pineapple blossom? spray and kill

In the culture method of pineapple, it has been introduced that it needs to pay attention to in the process of growth. if the flower friends do not pay attention, the insects will come to the door. What about the bugs in the pineapple flowers? find out what kind of insects they are, and then solve them. The following are the common pests of three species of pineapple, as follows:

1. Scale insects

The shell insect harms all flowers, so it is also one of the pests of pineapple flowers. It is observed that scale insects mainly harm the leaves of pineapple flowers, and when they are serious, the leaves will yellowing, withering and even falling. The solution to the yellowing of pineapple leaves has been introduced before. let's take a look at the solution to scale insects.

Solution: when it is found that it is harmful to scale insects, it should be solved immediately. A small amount of shell insects can be scraped off directly. When there are a large number of scale insects, 50% of parathion can be used for spray killing.

2. Spodoptera litura

Spodoptera litura, also known as Spodoptera litura, is also one of the pests of pineapple flowers. It usually hides in the dark places such as basin soil and the bottom of the basin during the day, and comes out in the evening to feed on the petals, stamens and pistils of pineapple flowers.

Solution: when the bug is found, it should be sprayed immediately. As for what kind of medicine is used, the insect-resistant pesticides on the market can be used.

3. Red spider

Red spider, one of the common insect pests of pineapple flowers, mainly lives on the back of leaves or the base of leaf axils of pineapple flowers, and will prick and suck leaves, buds and leaf sap, affecting normal growth and development. When attacked by the insect, the light ones will affect the appearance, and in serious cases, it will lead to the death of the whole plant.

Solution: the red spider is small, which is difficult for us to detect with the naked eye, but once found, it should be solved quickly. When there are a small number of bugs, rinse with clean water; for too long, spray 1000 times of dimethoate solution, once every 4 days, 2-3 times in a row.

Diseases of pineapple flowers and their solutions

There are bugs in the pineapple flowers. We should know what to do after reading the above contents. However, in addition to being attacked by insects, the disease also endangers pineapple flowers all the time, and there are three main diseases of pineapple flowers, namely, heart rot, root rot and leaf tip yellowing. The specific symptoms and solutions are as follows:

1. Heart rot

The disease is not common, but it is one of the common diseases of pineapple. When suffering from this disease, the tissue at the base of the pineapple mosaic tube becomes soft and rotten, with a bad smell. If you do not move it for a long time, the leaf tube will fall down by itself.

2. Root rot

After suffering from the disease, the root tip of pineapple will turn black and brown or rot, and do not grow lateral roots, thus affecting the absorption of water and fertilizer by the plant, resulting in slow growth and weakening of pineapple. It is understood that heart rot or root rot may occur in the season of high temperature and humidity.

The solution of heart rot and root rot: After discovering the above diseases, flower friends can irrigate the leaf tube with 75% manganese zinc 400 times solution or 40% ethyl phosphine aluminum 400 times solution once a month, 3 times in a row can be cured.

3. Leaf tip yellowing and withering

Another disease of pineapple flowers, it is generally related to moisture, once the water is improper, or the air humidity is low, it will lead to too high in the soil salt and cause salt damage. At this time, leaf tip yellowing and withering will come to the door, light will lead to leaf yellowing, serious plants will die directly.

Control methods: watering, try to choose less salt water, if you choose household water, should be used after exposure to the sun.
