Culture methods and matters needing attention of potted asparagus

Asparagus, also known as Yunpian pine, prickly asparagus, cloud bamboo, etc., is an evergreen plant belonging to the asparagus family, with slightly fleshy roots, soft and clumpy stems, up to a few meters high, with extremely high ornamental plants, which can be placed in the living room and study, purifying the air and adding a scholarly flavor at the same time. Let's take a look at the breeding methods of asparagus.

Culture environment 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 ℃. Born in the mountains, but also cultivated in the garden.

Propagation methods of asparagus

1. Sowing: sowing is the main method of propagation of asparagus. When the pericarp of asparagus seed blackens and softens, it is ripe, then it should be picked gradually according to the degree of maturity, rubbed to remove the pulp, cleaned with clean water, dried and stored semi-dry. Sowing in early April can be used as a commercial seedling or furnished indoors in the autumn of that year. The sowing substrate is generally fine sand and the container is tile basin or wooden box. Put the seeds on the basin soil at a distance of 2 cm to 3 cm, 2 to 3 seeds in each hole. After sowing, it is covered with fine sand 5 mm thick, covered with glass or plastic film, the temperature is kept at 20: 25 ℃, and water is often sprayed to keep the basin soil moist. About 30 days after sowing, the seedlings began to sprout. When the height of the seedling is 4-5 cm, it can be transplanted and cultured, and when it is 8-10 cm, it can be planted in the pot.

2. Ramet: the 3 ~ 5-year-old plants of asparagus grow thickly and can be propagated. When changing pots in spring, use a sharp knife to divide the tufted stems and roots into 2-3 clumps, so that each clump contains 3-5 branches and buds, and then plant them on the pot. 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 properly controlled in the future, otherwise it is easy to cause yellow leaves.

Bonsai production of asparagus

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.

Culture methods of asparagus

1. Pot soil: fertile sandy loam should be used in the cultivation basin soil of 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 for fertilizer, but it can not be short of fertilizer. Limited by potted soil, nutrients must be replenished in time to meet the growth requirements. In the process of fertilization, it is necessary to apply more and less, and do not apply thick fertilizer, otherwise it will cause leaf yellow. 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. Do not apply too much fertilizer at flowering stage, and topdressing liquid fertilizer 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.

Watering method of asparagus

The amount of watering asparagus should be flexibly watered according to different conservation environments, seasons and even potted soil, and should not blindly copy the experience of other flower friends. Watering in winter, spring and autumn should be properly controlled, and the surface of potted soil should be watered again. If you find it difficult to grasp the amount of water, you can also take large and small water alternately, that is, after 3 or 5 times of small water, water can be watered once, so that the basin soil remains moist and does not contain much water. Water should be watered in the morning and evening in summer, and a little more water does not hinder it. In summer, in addition to normal watering, you can often sprinkle water on the ground around the plant and spray branches and leaves with clean water to increase air humidity.

Pruning methods of asparagus

1. 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. Pruning of the whole plant: if the branches and leaves of the whole plant grow poorly due to strong sunburn or 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.

3, vine branch pruning: vine branch is generally weak and slender. If you don't want to leave seed and make the plant look good, it can be cut off from the root at one time. If you want to increase the number of leafy branches or fill a vacancy, you can cut it short in a certain position, and pay special attention to the comprehensive management of small fat when pruning.

What if the leaves of asparagus turn yellow?

1, the light is too strong: asparagus likes semi-shade, avoid strong light, especially in summer to avoid direct sunlight, otherwise it will cause branches and leaves withered and yellow. The flowerpot should be moved to a cool place and water is often sprayed on the branches and leaves to increase air humidity.

2. Improper watering: asparagus likes to be moist but afraid of waterlogging, so the basin soil should be kept dry and wet. Generally watering can make the topsoil moist. More water is easy to rot roots, less water is easy to dry tip, in the dry season should be more to spray water to the leaves.

3. Improper fertilization: if the application of topdressing is too thick or immature fertilizer is applied, it is easy to cause "root burning" and lead to leaf drying and shedding. On the contrary, if the potted soil is barren, the leaves will turn yellow due to lack of nutrients.

4. Poor winter management: asparagus likes warmth and should be sunny in winter. In winter, if you put it in a place where no light can be seen for a long time, poor ventilation or cold, it is easy to cause withered and yellow leaves. Generally, the room temperature should be no less than 12 ℃, and it should be placed near the south window, and watering should be controlled properly.

5. the cause of poisoning: asparagus is afraid of smoke and dust, and if it encounters poisonous gas, the branches and leaves are easy to turn yellow. In addition, if the plant is too large, the flowerpot is too small or damaged by insect pests such as shell insects, it will also cause branches and leaves to turn yellow, so the pot should be changed and controlled in time.

6. causes of diseases and pests: once asparagus is infected with shell insects and other pests, it will also cause withered and yellow branches and leaves, so it should be controlled in time.

The method of hydroponic culture 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 roots of asparagus have been reborn a lot, then we can put on a bottle of static hydroponics, it is best to use ceramsite to fix it.

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.

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

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.

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.

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.

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.

Cultivation methods and points for attention of asparagus, a small indoor potted plant

Asparagus, also known as Pinus elliottii, Radix Scutellariae, Phyllostachys pubescens, Latin name: Asparagus setaceus, climbing plant, up to a few meters high. The root of asparagus is slightly fleshy, the stem is soft and tufted, slender. The stem has many branches, nearly smooth. Leaflike branches, setose, slightly trigonous; scalelike leaf base slightly spiny spur or inconspicuous. The flowers are white, with short pedicels, and the florescence is from September to October. The berries appear purple-black when ripe, with 1-3 seeds. The fruit period is from winter to spring.

Native to South Africa, it 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 very high ornamental plant, can be placed in the living room, study, change the air at the same time also add bookish flavor. Root medicine can treat acute tracheitis and has the function of moistening the lung and relieving cough.

Culture methods and matters needing attention of asparagus

1. Adequate nutrients to avoid nutrient loss. Some are due to the hardening of basin soil and the decrease of root activity due to poor ventilation, which affects the normal growth of plants. In addition to changing the basin with soil rich in organic matter in spring, we should often loosen the surface of the basin soil and pay attention to strengthening fertilization.

2. Water more and keep moist. Should always keep the basin soil moist, and often spray water to the plant, the water temperature had better be the same as room temperature, and put asparagus in a place with high air humidity. Mixed fertilizers should be properly applied in the growing season to make the plants healthy and strong and enhance their resistance.

3. The amount of water should be appropriate, and too much is not good. It should be moved to the shade or the edge of the curtain window to avoid direct exposure to strong light, and pay attention to not watering too much.

4. Pay attention to the weather changes. When a typhoon comes, asparagus should be moved indoors. Its decay is mainly caused by strong winds in the hot summer season, or long-term stagnant water in flowerpots. So in summer, we should pay special attention to guard against thundershowers or typhoons.
