Two points for attention in planting asparagus

1. Replacement of basin soil

Asparagus should change the flowerpot every one to two years.

2. Pruning

The pruning time of asparagus is the most suitable in spring, and the pruning method is to keep the plant type according to the positive direction of asparagus.

As long as you pay attention to these two points, it will not be a big problem for your asparagus to grow well, so are you already a good asparagus now? What are you waiting for? plant a unique asparagus of your own!

Matters needing attention in how to raise asparagus

Asparagus can not only improve cultural accomplishment, but also regulate the body to a certain extent, which is of great benefit to human health. Now let's learn about the culture methods of asparagus.

Culture methods of ● asparagus

1. Potted soil: fertile sandy loam should be used to cultivate asparagus, which should be warm and humid, rich in rotten branches and good drainage. Generally, it can be prepared in the proportion of 4 parts of garden soil, 2 parts of rotten leaf soil, 2 parts of compost soil and 1 part of sand. And to change the soil regularly to add fertilizer. If excessive fertilization causes "watering roots", it is necessary to pour the pot to remove the fertilizer, irrigate the soil with clean water, and then put it into the new soil for breeding.

2. Watering: watering is the key point of asparagus cultivation and culture. too much watering and too wet basin soil can easily cause root rot, and too little watering will lead to scorched and yellowed leaf tips. Therefore, in the process of watering, it depends on the weather, growth and the dry and wet condition of the basin soil, so that if it is not dry, it will be watered thoroughly. When the weather is hot and dry, water spraying can be used to humidify and cool the leaves, but less watering is needed in winter.

3. Fertilization: asparagus is not good at fertilizer, but it can not be short of fertilizer. Limited by potted soil, asparagus culture must replenish nutrients in time to meet the growth requirements. In the process of fertilizing asparagus, it is necessary to apply more times and less amount, and do not apply thick fertilizer, otherwise it will cause leaf yellowing. Generally, you can choose to apply rotten thin liquid fertilizer once a month, and after the plant grows and finalizes, you can properly control and reduce fertilization.

4. Lighting: asparagus culture can not be exposed to the hot sun, hot season, should be placed in a cool and ventilated place. At the same time, asparagus flowering is not only afraid of wind, but also afraid of rain, should pay attention to good ventilation, good weather can be properly placed outside to receive sunlight. The temperature of potted asparagus in winter should be kept above 5 ℃ to avoid freezing.

5. Display: asparagus is mostly used for indoor desk decoration. Because asparagus is afraid of smoke and dust, if toxic gases are encountered, the branches and leaves are easy to yellow. therefore, asparagus should be placed in a clean and well-ventilated environment.

Matters needing attention in the Culture of ● asparagus

1. Asparagus likes warmth and avoids bright light.

Asparagus culture needs to create a growth environment of more than 15 ℃ in winter, while it should be kept away from strong light in summer.

Second, asparagus likes to be wet and afraid of soaking roots.

Asparagus growth period should be fully watered, often keep the basin soil moist, but not too much watering, let alone stagnant water, otherwise easy to rot roots, fallen leaves, reduce ornamental value. Watering should be reduced after autumn.

Cultured asparagus should not be frequently watered with "waterlogged soup", but should often be sprayed on the leaf surface. It is generally suitable for watering in summer, spraying water twice a day on the leaf surface, and spraying water on the leaf surface every 3-4 days while keeping the soil moist in winter.

Third, asparagus likes to be fat.

The scientific fertilization method of organic fertilizer which is especially fond of rotten maturity is to apply thin fertilizer once a week in spring and autumn and once every 15-20 days in winter.

Fourth, put asparagus away from marble decorative materials

Asparagus has a strong ability to absorb gaseous mercury, but it will also cause serious damage to itself while absorbing mercury gas. Therefore, when placing asparagus, you should stay away from marble and other building decoration materials that release mercury gas.

5. Pruning in time

Branches that are too dense should be pruned in time. If there are too many roots of iniquity, we should remove or divide the basin in time. At the same time, we should also pay attention to bundling and scaffolding, so as to maintain a dense and elegant shape.

Knowledge about the breeding methods of asparagus is introduced here. Asparagus is a kind of plant that is difficult to breed. Therefore, few families choose to plant it, and its value is relatively high.

Culture methods and matters needing attention of asparagus bonsai

Asparagus, also known as Yunpian pine, prickly asparagus, cloud bamboo, etc., is a perennial plant of the asparagus family, native to South Africa, distributed in central China, northwest, the Yangtze River basin and all parts of the south, up to a few meters high, with extremely high ornamental plants, can be placed in the living room, study, purify the air and add a scholarly flavor at the same time. Let's take a look at the breeding methods and matters needing attention of asparagus.

Growth habits of asparagus

Asparagus likes warm, humid and semi-overcast ventilated environment, can't bear cold and drought in winter, can't pour too much water, root will rot, and avoid direct sunlight in summer. It is better to cultivate loose, fertile and well-drained sandy loam rich in humus. It is suitable to keep the room temperature between 12-18 ℃, ventilation and heat dissipation when the temperature is over 20 ℃, the suitable growth temperature is 15-25 ℃, and the overwintering temperature is 5 ℃.

Propagation methods of asparagus

Asparagus is mostly propagated by ramets. Asparagus plants of 3-5 years old grow thickly and can be propagated. Ramet selection is carried out when changing pots in spring. The clump stems and roots are divided into 2-3 clumps with a sharp knife, so that each clump contains 3-5 branches and buds. Then plant it on the pot respectively. When ramet, damage the root system as little as possible, water thoroughly after planting, put it in a semi-shady place, and pay attention to moisturizing and shading. Watering should be controlled properly in the future, otherwise it is easy to cause yellow leaves.

Culture methods of asparagus

1. Potted soil: fertile sandy loam should be used in the basin soil of cultivated asparagus, which should be warm and humid, rich in rotten branches and good drainage. Generally, it can be prepared in the proportion of 4 parts of garden soil, 2 parts of rotten leaf soil, 2 parts of compost soil and 1 part of sand, and the soil should be changed and fertilized regularly. If excessive fertilization causes "watering roots", it is necessary to pour the pot to remove the fertilizer, irrigate the soil with clean water, and then put it into the new soil for breeding.

2. Watering: watering is the key point of asparagus cultivation and culture. too much watering and too wet basin soil can easily cause root rot, and too little watering will lead to scorched and yellowed leaf tips. Therefore, in the process of watering, it depends on the weather, growth and the dry and wet condition of the basin soil, so that if it is not dry, it will be watered thoroughly. When the weather is hot and dry, water spraying can be used to humidify and cool the leaves, but less watering is needed in winter.

3. Fertilization: asparagus is not good at fertilizer, but it can not be short of fertilizer. Limited by potted soil, asparagus culture must replenish nutrients in time to meet the growth requirements. In the process of fertilizing asparagus, it is necessary to apply more times and less amount, and do not apply thick fertilizer, otherwise it will cause leaf yellowing. Generally, you can choose to apply rotten thin liquid fertilizer once a month, and after the plant grows and finalizes, you can properly control and reduce fertilization. During the growing period, thin fertilizers containing ammonia and phosphorus should be applied once or twice a month to promote the growth of branches and leaves, as well as other liquid fertilizers. It should be noted that not too much fertilizer should be applied at flowering stage, and liquid fertilizer should be applied twice in May-June and September-October respectively.

4. Lighting: asparagus culture can not be exposed to the hot sun, hot season, should be placed in a cool and ventilated place. At the same time, asparagus flowering is not only afraid of wind, but also afraid of rain, should pay attention to good ventilation, good weather can be properly placed outside to receive sunlight. The temperature of potted asparagus in winter should be kept above 5 ℃ to avoid freezing.

5. Display: asparagus loves a clean and well-ventilated environment. If stimulated by harmful gases such as smoke, gas and pesticides, the leaves will turn yellow, curl and even die. Therefore, asparagus should be placed in a clean, well-ventilated environment, away from marble decorative materials that release mercury gas.

Matters needing attention in asparagus culture

1. Asparagus is not cold-resistant and cannot survive the winter outdoors in the north. When the temperature drops, asparagus should be moved indoors in time, and a growing environment of more than 15 degrees Celsius should be provided in winter.

2, should not water frequently, should often spray water to the leaf surface. Spray water once or twice a day in summer and once every 3 or 4 days while keeping the soil moist in winter.

3. To keep the basin soil semi-dry and wet, too dry basin soil will cause asparagus leaves to turn yellow or branches and leaves to scorch.

4. Do not water the flowers directly with tap water. Place them 1 to 2 days in advance and keep the water temperature not too cold.

5. do not apply raw fertilizer (some people raise asparagus and pour the boy's urine directly into the root of asparagus, resulting in burning to death), raw fertilizer should be mature.

6. Apply thin fertilizer once a week in spring and autumn and once every half a month in winter. It is best to use compound fertilizer.

7. Asparagus does not like smoke and dust. If you use a coal stove or charcoal fire for heating in winter, you should be properly ventilated every day.

8. Asparagus should stay away from marble decoration items. Asparagus has a strong ability to absorb gaseous mercury, it should be noted that asparagus absorbs mercury gas, which will also do harm to itself. Therefore, when placing asparagus, you should stay away from the decorative materials that release mercury gas.

9. Asparagus should be pruned in time, the branches are too dense to affect ventilation, daylighting and ornamental, and should be pruned in time. If the sinful root multiplies too much, it should be divided into pots in time.

10. Binding asparagus can make the posture of asparagus more beautiful, but it is not suitable to use rope with too thick or too different color. Bamboo strips and wood strips should not be too thick, otherwise, the slender asparagus will be set off too weak.

Production method of asparagus bonsai

1. Material selection first: one asparagus with a height of about 20 cm, two asparagus with a height of more than 10 cm, a shallow basin of irregular white marble and its supporting frames, a number of rocks with a height of about 10 cm, and an appropriate amount of soil and moss.

2. Bonsai shaping: spread a thin layer of cultivation soil on the shallow basin surface of white marble, plant the tallest asparagus and curved branches and leaves to the right end of the basin, plant the second height asparagus not far from the left side of the first asparagus on the right side of the basin, and then put the shortest asparagus at the junction of 1ploke 3 and 2x3, and the curved branches and leaves of asparagus should also be to the left, so as to achieve the coordination and unity of the three asparagus. Then adjust the position of asparagus in the basin to achieve natural beauty.

3. Point stone and spread moss: put a number of mountains and stones on the basin surface on the right side, and cover the moss on the basin surface to achieve the artistic effect of greening. Finally, spray asparagus and moss with clean water to make the culture soil moist.

How to trim asparagus best

1. Lack of pruning of leafy branches: when the growth position of leafy branches on the main branch is not ideal or missing for some reason, short pruning can be carried out at the appropriate position of the main branch to force the hidden buds to germinate. In general, the height of truncation is the height of leafy branch germination, and the position of prickles on the branch is the location of leafy branch germination, and the thicker the branch is, the higher the germination rate of hidden bud is.

2. whole plant renewal pruning: if the branches and leaves of the whole plant grow poorly due to strong sunburn or basin soil, lack of fertilizer and some unknown reason, the whole plant can be renewed. When renewing and pruning, all the leafy branches can be cut off, but we should pay attention to the parts of the branches, because they determine whether the distribution of the remaining branches is uniform. Pruning in the growing season is generally high and easy to sprout new branches, and the amount of water should be reduced appropriately after pruning, never make the basin soil too wet, otherwise it will lead to pruning failure.

3. Trailing branch pruning: trailing branches are generally weak and slender. If you don't want to leave seed to make the plant look good, you can cut off the root at once. If you want to increase the number of leafy branches or fill a vacancy, you can cut them short in a certain position. When pruning, special attention should be paid to the comprehensive management of small fat and so on.

Hydroponic culture method of asparagus

The main results are as follows: 1. The sturdy and well-developed asparagus is selected as the mother material of hydroponic culture, the soil of asparagus is taken out from the flowerpot, the soil of its root is carefully washed, the rotten root is removed, and part of the old root is cut off. Clean the leaves and plants with clean water to avoid damaging the plants. Asparagus takes root slowly, so be careful not to hurt the roots of asparagus.

2. The washed plant is fixed with a planting basket, and when fixed, the root should be fully stretched, and then the plant together with the planting basket should be soaked in 1 ‰ carbendazim solution for 30 minutes, and put in a cool place. After the root system becomes soft, the next operation can be carried out.

3. Load the special nutrient solution of asparagus into the nutrient pool and plant the above treated plants on the floating board (pay attention to keep part of the roots exposed to the air). Spray water to the leaf twice a day, under the condition of 15-25 ℃, new roots can grow in two weeks, and foliar fertilizer should be added every other week.

4. Three to four weeks later, the root system of asparagus has been reborn a lot, at this time you can put on a bottle of static water culture, it is best to use ceramsite to fix.

5. Asparagus prefers a semi-humid environment. It is usually placed near a window with light, but not in a place where the sun shines directly, and it is ventilated. A tray with water is still placed under the container and replenished frequently.

6. The hydroponic culture of asparagus had better use the special nutrient solution of asparagus. The maintenance of hydroponic culture of asparagus is much easier than that of soil cultivation. Usually, you only need to pay attention to changing water, about 10 days in summer and 20 days in winter.

The reason for the yellowing of asparagus leaves

1, strong light exposure: asparagus culture like semi-shade, summer should not have strong direct sunlight, otherwise it will cause branches and leaves withered and yellow. The solution is to move the flowerpot to a cool place and spray more water on the branches and leaves to increase humidity.

2. watering is incorrect: asparagus likes to be wet, but it is also too wet and waterlogged, so it is best to keep the basin soil dry and wet in the process of culture, generally not dry and not watered, but do not let the basin surface have too much waterlogging when watering. If there is too much watering, you can not water temporarily, but only spray water to the leaves to moisturize asparagus.

3. Improper fertilization: excessive fertilization or immature fertilizer will lead to yellowing and shedding of asparagus leaves. On the other hand, the nutrient of the planted pot soil is too poor, which will also lead to the yellowing of asparagus leaves. Therefore, when applying fertilizer, we should pay attention to Pushi, but the number of times is more but less, and we should use rotten fertilizer, and for the situation that has occurred, we can take to change the basin soil to solve. It is worth noting that it is not suitable to apply fertilizer in winter low temperature period and summer high temperature period.

4. Gas poisoning: asparagus is very afraid of smoke and dust. if it is often attacked by harmful gases such as smoke and dust, the branches and leaves of asparagus will be yellowed. If this happens, the flowerpot should be moved away from the original position in time, and the work of foliar sprinkler and dust removal should be increased.

5. Causes of insect pests: shell insects are the most common insect pests in asparagus culture. When shell insects are found, they should be wiped off with wet cloth strips in time. In serious cases, they should be bought at the drugstore for prevention and control, and the pot soil should be changed in time. When changing the basin soil, the old residual roots can be cut off to reduce nutrient consumption.

6. Management mistakes: asparagus culture should keep it at a certain temperature, especially in the sunny position in winter. If asparagus is placed in places that lack light, poor ventilation and cold for a long time, it is easy to make the leaves of asparagus withered and yellow. The temperature of asparagus culture in winter should not be lower than 12 ℃, and it should be placed in a place with good light, and watering can be reduced appropriately.
