Cultivation methods and precautions 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. Vine branch pruning: vine branches are generally weak and slender. If you don't want to leave seeds to make the plant look good, you can cut off from 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.

A complete solution to the culture method of asparagus bonsai

Asparagus originates in South Africa and is distributed in central China, northwest China, the Yangtze River Basin and the south. Its nature likes the warm, humid and semi-overcast ventilated environment, does not tolerate severe cold in winter, does not bear drought, and avoids direct sunlight in summer. Asparagus is a plant with high ornamental value, which can be placed in the living room and study, which can also increase the flavor of books while purifying the air. Root medicine can treat acute tracheitis and has the function of moistening the lung and relieving cough. Today, I would like to briefly introduce the culture method of asparagus bonsai. The cultivation method of asparagus bonsai basin soil requires that the basin soil of cultivated asparagus is suitable to use fertile sandy loam, 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. Watering method: watering is the key point of asparagus cultivation and culture, too much watering, too wet basin soil, easy to cause root rot, 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, you can use water to spray the foliage to humidify and cool down, and water less in winter. Fertilization method: asparagus is not good fertilizer, but also can not lack of fertilizer, limited by potted soil, asparagus culture must timely supplement nutrients 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. After the plant grows and finalizes, it can be properly controlled to reduce fertilization. During the growth period, thin fertilizer containing ammonia and phosphorus should be applied 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 during flowering, and liquid fertilizer should be applied twice in May-June and September-October respectively. Lighting conditions: 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. Location: 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, and away from marble decorative materials that release mercury gas.

Pruning and shaping: when the growth position of the leafy branch on the main branch is not ideal or missing for some reason, short pruning can be carried out in 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 greater the thickness of the branch, the higher the germination rate of hidden buds. If the branches and leaves of the whole plant grow poorly due to strong sunburn or over-drying of basin soil, lack of fertilizer and for 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.

A complete Collection of Culture methods and points for attention of asparagus

Asparagus is not very sensitive to temperature, generally above 10 degrees, frost injury will occur below 5 degrees, between 15 degrees and 25 degrees is the most suitable for asparagus growth, the temperature above 32 degrees will stop growing. So what are the breeding methods and matters needing attention of asparagus?

1. Selection of flowerpots for asparagus culture

(1) flowerpot requirements: muddy flowerpots, plastic pots, porcelain pots and pottery pots can be used for cultivation.

(2) flowerpot size: asparagus can be planted in pots with a diameter of 14-18 cm. Now it is cultivated in flat bonsai pots.

two。 The pot method of asparagus culture

When the seedlings grow to more than 5 cm, they can be divided into pots and planted in pots with a diameter of 7 cm and 10 cm. The basin soil should be mixed with 5 parts of rotten leaf soil, 2 parts of garden soil, 2 parts of river sand (sand soil) and 1 part of rotten barnyard manure.

Asparagus is a flower cultivated for many years, but the pot should be changed once a year before sprouting in early spring, the old soil should be removed and the new culture soil should be replaced; according to the plant size and growth, the larger pot should be replaced or the original pot should be used; the withered branches and yellow leafy branches should be cut off to maintain a beautiful plant shape.

3. Watering method of asparagus culture

Watering is the key problem in the cultivation and management of asparagus. Therefore, watering has become an important measure to raise asparagus well. Too much watering, basin soil is too wet, easy to cause root rot, leaf yellow shedding; too little watering, basin soil long-term drought, but also easy to cause leaf tip yellowing and shedding. Therefore, the amount of water and times of watering during the growth period should be determined according to the weather, growth condition and the dry and wet condition of the basin soil.

Watering should grasp the principle of "dry and wet". If you don't do it, you should water it thoroughly. That is to say, when the surface of the basin soil is dry, the water should be watered until the bottom of the basin is watered; you cannot pour "half of the water", that is, the amount of water only moistens the topsoil, and the soil below is dry, so that the bottom roots can not absorb water, so that the branches and leaves will be withered and yellow. When the weather is dry or hot, in addition to keeping the basin soil moist, it is also necessary to often sprinkle water on the ground around the plant and spray the branches and leaves with clean water to increase air humidity. In winter, watering should be controlled, watering times should be reduced, and branches and leaves should be sprayed with water close to room temperature every 5 to 7 days to keep the plant green and fresh.

4. Lighting requirements of asparagus culture

Asparagus is a shade-loving flower that grows well under the condition of scattered light. The sun is not strong in early spring and autumn, so it is good for growth to be placed in a sunny place indoors; in winter, it should be placed in a sunny place; after summer, it can be moved to a cool place outside without direct sunlight or where there is bright scattered light indoors.

5. Fertilization methods for asparagus culture

Asparagus prefers to be fat. In order to make the plant grow healthily, fully mature thin organic liquid fertilizer can be applied every 15 to 20 days in spring and autumn, nitrogen, phosphorus and potassium fertilizer can also be applied, and 0.1% urea and 0.1% potassium dihydrogen phosphate mixture can be applied. Stop fertilizing during hot summer and overwintering. However, fertilization should also be controlled during the growth period to avoid overgrowing and drawing growing vines, destroying the plant shape and affecting the ornamental effect. In order to make the plant low, it is necessary to apply less liquid fertilizer, especially less nitrogen fertilizer.

6. Four Seasons Management of asparagus Culture

(1) Spring management

From March to April, the old plants of asparagus were changed and pruned properly before changing pots. As asparagus likes the damp environment, it can be decorated indoors for a long time. However, due to the low indoor air humidity, attention should be paid to increasing indoor air humidity.

Spring temperature is suitable, asparagus growth is more exuberant, seedlings can be fertilized twice to ensure adequate water supply, while pay attention to increase air humidity, otherwise the leaf color is easy to aging and fall off, affecting ornamental.

(2) Summer management

In summer, asparagus can be placed in a brightly lit place to keep the basin soil moist, sprinkle more water around it, strengthen ventilation to cool down, and do not apply fertilizer.

(3) Autumn management

When the temperature is cool in autumn, asparagus will grow again. Attention should be paid to the supply of water and fertilizer and the supplement of air humidity. After the temperature drops at the end of autumn, we should pay attention to maintain the indoor temperature, gradually move the asparagus to the place with light by the window, reduce the watering times, and keep the basin soil moist.

(4) Winter management

Asparagus is not resistant to cold. The temperature below 5 ℃ will cause defoliation, and the room temperature should be kept above 5 ℃. At this time, asparagus is in a state of stagnant growth, so we should ensure a certain amount of light, reduce watering, make the basin soil slightly dry and do not apply fertilizer.

When the room temperature is kept above 10 ℃, asparagus can also grow normally, so the basin soil should be moist and no fertilizer should be applied.

7. Matters needing attention in asparagus culture

The main results are as follows: (1) if it is found that the new branches of asparagus turn yellow, 20 times of rotten liquid fertilizer or 1000 times urea solution should be applied 1-2 times, and the light should be increased in the morning and evening.

(2)Wenzhu likes warm, wet, semi-shade-resistant, not cold-resistant. It is impossible to overwinter in the open field in Jiangnan area. Potted asparagus in summer and autumn should be placed in a semi-shady place that is not directly exposed to the sun. In winter, it should be placed indoors in a south-facing sunny shelter.

(3)Potted asparagus should be cultivated especially in loose, well drained, sandy soil containing humus. Cultivate asparagus had better choose the clay tile basin with good drainage and gas-making performance, and the lower layer should be discharged with sand and stones as drainage layer.

(4)The key problems in potted culture and management of asparagus are fertilization and watering, avoiding rain and direct sunlight, otherwise it is easy to cause scorched shoots and withered branches of asparagus, and the color of plants turns yellow. Do not apply thick fertilizer in the growth period, depending on the growth of seedlings, apply thin and light fertilizer to control nutrients, do not make the plants grow excessively, and keep the plant type beautiful. Generally speaking, the fully fermented liquid cake fertilizer water (bean cake or vegetable cake) is applied every 7 to 10 days, and the concentration is 30% fertilizer and 70% water. If the plant grows vigorously and grows vines, it can be erected or trimmed appropriately.

(5)Although Wenzhu likes to be wet, it is forbidden to water too much. If the water is watered too much, the accumulated water in the basin cannot be discharged for a while, and the roots are easy to rot, even causing plant death. Less water, drying on the pot will also cause yellow leaves or scorched shoots. Therefore, whenever the soil surface whitens, it needs to be watered thoroughly. The standard to master is that after water is poured thoroughly, water can be quickly discharged from the bottom of the basin. It is best to have a slightly wet high temperature growing season and a dry low temperature dormant season. Summer high temperature weather should be sprayed on the leaves, winter can be used with room temperature similar to the water wash leaves to keep the leaves clean, full of vitality.

8. Breeding method of asparagus culture

Bamboo can be used for sowing and sub-propagation, commonly used for sowing propagation.

Sowing propagation should be collected after the seeds mature harvest, remove berry skin, dry in the shade after storage. Generally sowing in the same year, the germination ability of the next year is reduced. Sowing can be carried out in March to April, and seed soaking is required for 1 to 2 days before sowing. The seeds are sown closely, the spacing between seeds is about 2 cm, the soil is covered with 0.5~1 cm after sowing, the humidity is kept at a certain temperature after sowing, and the germination can be achieved in about 25~30 days. Seedling height 3~4 cm seedlings transplant once, plant spacing 5 cm; seedling height 5~7 cm can be potted cultivation maintenance.

The ramets of 4~5 years old were used for ramets propagation, but the plants were often irregular in shape. Therefore, many do not use the split propagation.

The cultivation methods and precautions of Wenzhu
