With the improvement of living standards, people's tastes are getting higher and higher. Living environment, such as asparagus leaf scenery, Alice and exquisiteness, is often beautified with coffee potted tables placed on bookshelves and tables. But because it grows fast, the small and beautiful appearance can't last long. It must be plastic. Now the plastic methods are introduced as follows:

1, pot control method: the size ratio of flowerpot to plant should be 1:3, so as to limit the growth of root system and keep the size of plant unchanged.

2. Removing the growing point: removing the growing point at the 2-3 cm position of the new bud can promote the branches of the regenerated stems and leaves, and no longer control their spread, so that the branches and leaves are flat and full.

3. Use the phototaxis of asparagus: turn the directional flowerpot in time, and the growth of branches and leaves can correct the shape and keep the plant shape unchanged.

4, covering material method: that is, it is difficult to cover leaves or paper in the sun, so on the growing branches, an object is blocked by dry rotation or bending growth, thus achieving the purpose of modeling. Comprehensive application

5. Several modeling methods:

(1) Tower: Choose 2-3 tall, beautiful and tall stems as the main peak, remove the growing point of each stem, fix the row height at 30-35 cm, and keep the rest branches and new stems not higher than the peak. According to its thickness, the new bud decides whether to pick the growing point from the stem. If the stem is thicker than the main peak, it should be compared with the thin peak when it is harvested, and it should be compared when it grows up. At the same time, there is a price to pay for constantly adjusting plant morphology by using physical laws and their phototaxis.

(2) Double-cluster type: two asparagus plants planted in a flowerpot, one high and one low, are about 30 cm high and 65,438+08 cm low, and then grow into the shape of an asparagus tower.

(3) Natural style: The natural growth of plant type and asparagus is mainly based on the trend and application of picking growing points and physical covering, which makes the branches and leaves stretch and gives people a natural beauty.

It should be noted that asparagus shaping must be combined with fertilizer control. That is, under the condition of room temperature 15- 18℃, water once for a week to keep the basin soil moist (finger pressure is appropriate). Not or rarely fertilized.

Breeding method:

Planting asparagus can combine tillering. The seeds are white, and the ripe purple berries are from1February to April. When the fruit color is appropriate, collect the seeds, dry the seed coat and seeds, then mix the sowing sand and humus matrix in equal amount, cover the soil (not too thick), water it and keep it moist. Germinate at 20-30℃ for about one month. When the height exceeds 5 cm, it can be transplanted into a small pot. -Like a densely growing 3-5-year-old plant, it can be propagated by ramets. Generally, in spring, the stems and roots are divided into 2-3 clusters with a sharp knife, so that each cluster contains 3-5 buds, and then planted in flowerpots. When the roots of ramets are as few as possible, the later ramets should be protected from moisture and light. In winter

1。 Seed propagation asparagus berries gradually mature. When it becomes a deep purple berry, it can be harvested. After harvesting berries, kneading and removing seed shells. You can wash it after the broadcast. If the indoor temperature is lower than 15℃, we must wait until the spring sowing line comes. During this period, we should plant and sow sand in shallow pots according to indoor flower pots. Generally, the grain should be two centimeters, and the shell should not be too deep. It should be covered with glass or film to reduce water evaporation, keep the soil moist, and put it in a sunny place. After sowing, the temperature was kept at about 20℃ and germinated at 65438 05℃ and 65438 08℃ for 2530 days. When germination is needed in 3040 days, the seedlings will grow 3 cm and 4 cm high and can be transplanted.

2. In spring, change pots for ramet propagation and dig roots, and the roots will not hurt too much. According to the size of the plant, choose potted plants or the ground. After transplanting, water it and put it in the shade or shade. After watering, it should be properly controlled, otherwise the leaves will turn yellow easily.

Cultivation management:

Common asparagus potted humus soil, 65,438+0 garden soil and 65,438+0 river sand mixed as base fertilizer, planting base fertilizer with a small amount of decomposed organic fertilizer, its cultivation management is the most critical water use problem. Too much watering can easily lead to root rot and yellow leaves falling off; If there is too little water and the basin is too dry, it is easy to cause the sharp leaves to turn yellow and fall off. Therefore, it is necessary to properly master the right amount of water at ordinary times, do not dry it, and always keep the basin soil moist by pouring it. In addition to watering the basin in hot weather, they also need to spray leaves regularly to improve the air humidity; In late winter, the amount of water can be reduced appropriately. In the growing season, dilute liquid fertilizer should be applied 1-2 times a month to avoid applying thick fertilizer, otherwise the leaves will turn yellow. When setting, it can reduce the chemical fertilizer of plants, avoid overgrowth and affect the appearance of plants, and pay attention to the number of plastic decorations. It is suitable for growing in semi-shade, ventilated, paying attention to proper shading, especially in summer and autumn, avoiding direct sunlight to avoid yellowing of leaves. It is better to cultivate diffuse light somewhere indoors.

Cultivation techniques:

The key management of asparagus is watering. Leaves that turn yellow easily when watered too often grow badly, which can easily lead to rotten roots. Water should be adjusted according to plant growth and season. Water should be properly controlled in winter, spring and autumn. Generally, it is difficult to master the water before pouring the basin surface, and the size of the water can also be alternated. That is to say, after 35 times of small irrigation, 1 time is permeable, and the water in the upper and lower basins remains moist, but the amount is not much. You have to water it sooner or later in summer. The water is bigger and impartial.

The washbasin should be watered before it dries. Irrigation should be sufficient during the growth period, but not too much, otherwise the roots will rot easily, and the water will quickly penetrate into the soil, and there will be no water on the soil surface. Reduce watering after the end of autumn. Organic fertilizer, such as cake fertilizer and mature topdressing with water, should be applied every 20 days during the growing period. Keep it indoors in a warm place in winter.

Asparagus doesn't like fat very much, but potted plants, especially those planning to set seeds, should be supplemented with more nutrition. Asparagus fertilizer should be applied thinly, not thickly. In the growing season, the general organic liquid fertilizer is decomposed once every 1520 days. Asparagus likes slightly acidic soil. It can be combined with chemical fertilizer, and some alum can be used to improve the pH value of soil.

Asparagus should overwinter indoors, and the room temperature should be kept at about 65438 00℃, which is the best in winter. After outdoor maintenance, it should be moved to April of the following year.

When asparagus is planted, the branches and leaves are lush and the new vines grow rapidly, so it must be erected in time to facilitate ventilation and light transmission. Old people prune dead branches properly to promote the germination of new vines. Once bone meal or calcium superphosphate is applied before flowering, the seed setting rate will be improved.

For example, if asparagus is cut, the length of harvest is selected to realize branching. They are cut and a pile of spices is listed every 20, which is generally higher in winter than in summer and 20% in autumn.

1。 Plant spring plants or turn over pots to change the soil. Multiple pots. In the process of growth, it is required to mix the fleshy fibrous roots of the soil with humus soil sand for plants with a small amount of culture soil, and the soil should be well ventilated and drained. The second pot every year. Cover the roots and replace the big basin. The fiber around the basin is cut off, and the old part of the basin is taken out to add new loam. With plants, tall growth should be inserted into the scaffold.

2。 Warm asparagus should be kept indoors in winter, and the temperature should be kept above 10℃. 5℃ is not easy to be frozen, but it can be outdoors in winter in southern China. The optimum growth temperature is 15-25℃. At 32℃, Gaoding will stop growing and the leaves will turn yellow. If the sun shines directly, it will not only cause the leaves to turn yellow, but also cause anxiety. Not only will there be many poorly ventilated leaves, but they will also be weak. Therefore, asparagus should be provided, but it should not be kept indoors in a cool or shady place for a long time, but in a bright place indoors. It should be placed near the south window in late autumn and winter, which may be more common in some sunny places.

3。 Water Fertilization During the growth period of asparagus, water should be fully and regularly to keep the soil moist, but it should not be watered too much, let alone watered, otherwise the roots and leaves will rot easily and the ornamental value will be reduced. Water should be reduced in autumn. 65438+ topdressing 0-2 times in one-month growth period, containing dilute ammonia and phosphorus to promote leaf growth, and other liquid fertilizers are enough. It should be noted that excessive fertilization should not be visited twice in May-June and 9- 10. Watering should be flexible according to the size of plants, with the principle of seeing wetlands found. As long branches of plants, they should be set up in time and trimmed properly to keep the plants clean and tidy.

Maintenance precautions:

First, prevent the sun from being too strong and keep it in the shade. Although I like warm asparagus, the tip of the leaf will suddenly wither under strong light.

The second is to prevent watering too much or too little. Although asparagus likes to be wet, it should not be too wet. If the basin is too wet and the drainage is not smooth, the soaked roots will rot. Water too little or no water, because the big asparagus evaporates and absorbs less, which leads to the scorched leaves and ventilation.

The third is to prevent the pollution of harmful gases. Asparagus's favorite clean and ventilated environment, if the economy stimulates the passage of harmful gases such as smoke, gas and pesticides, the leaves will turn yellow, curl and even die.

Dwarfing method:

Climbing asparagus stems is sexual. If allowed to grow, it can reach several meters, and then waste the light of the country. Measures to shorten asparagus are:

Spring and summer 1 germination can't gain more weight, and farmyard manure can be applied once a month. Fertilizer should not be too large, light control principle. For older plants, it is best to apply little or no fertilizer. Only by changing the basin can the basin bottom be filled with fresh soil or a small amount of fertilizer. Therefore, no matter whether plants are young or old, they can maintain a stable growth trend.

2. Pay attention to regular pruning. Asparagus grows fast, so it needs to prune old branches and stems frequently to keep the posture of low bottom. At the same time, prune the vines in time to keep them beautiful, tall, dense and green.

3。 Select the dwarf variety asparagus. The tailless dwarf asparagus stems can keep a small size.

4。 It is dwarfed by chemical methods. When the new seedlings grow to 100cm, the growth height can be effectively controlled and increased by diluting 1000 times with paclobutrazol and spraying on the leaves.

Plus its ornamental value and ornamental time.

5. When the asparagus is at the end of the seedling stage, you can also use chlormequat or Sanxi in a proper amount, and you will wait for foliar spraying treatment, so the field of vision is very good.

Pest control:

Asparagus is the flower of permanent grass, some places are called yunzhu, and Cao Cao and Yunzhushan Songshan grass are perennial vines. Although asparagus has the characteristics of evergreen for many years, if it is not properly maintained, it will often have yellow leaves, which will affect the appreciation.

Why do men's bamboo produce yellow symptoms? According to the author's practice of protecting asparagus, the original text; It may be due to the following points: First, asparagus is left by the fire for a long time, not only the whole feather leaves turn yellow, but also the valve stem will dry up. Second, put asparagus on the adjacent TV, suggesting that it will gradually dry up. Third, if the strong light lasts too long, the plant will lag for the first time, and then the yellow leaves will fall off. Fourth, neglect watering, or only water the root system on the surface of the basin, without absorbing enough water, the leaves slowly turn yellow. Fifth, excessive watering is the root cause of ulcer, followed by leaf blight. 6. Improper fertilization, the concentration of farmyard manure is too high or decomposed, and it is easy to burn seedlings after drying, and it will turn yellow if it is not topdressing for a long time. Seventh, put it in a long-term environmental shade, and then turn yellow and delicate plants grow. Eight were damaged, causing the leaves to turn yellow.

In order to keep asparagus fresh and graceful, the measures to prevent leaves from yellowing should mainly focus on the following aspects:

First, the supervision of chemical fertilizers. In asparagus planting that does not require too frequent fertilization, topdressing should generally be decomposed into farmyard manure in spring, and dilute or low-concentration compound fertilizer solution should be added every 10 15 days, or rice water and bean water should be applied. It is not suitable for fertilization without summer heat and winter cold. But the amount of fertilizer should be there, just when. Water should be done without watering, once thoroughly, leaving no waterlogging on the basin surface. Dust sprayed on leaves will be removed regularly.

Second, proper placement. Like asparagus in a slightly damp, semi-cloudy and semi-sunny environment. Everyone should avoid exposure to the sun, but the visibility is fine; Secondly, we should be able to feel the air circulation; 3 TV is far from the stove; Fourth, heat preservation, low temperature should not be lower than 5℃. If the temperature is 0℃ and 4℃, keep warm with plastic cover.

Third, plastic surgery in time. In order to alleviate asparagus bunches and pruning, Laos should fill soil, change pots and reorganize redundant roots, stems and leaves to avoid excessive consumption of nutrients and improve the role of root protection and leaf protection. Secondly, cut off the local yellow leaves; Third, the stems should be cut off in yellow.

Causes of yellow leaves of asparagus:

(1) Too strong sunlight can easily cause the leaves to turn yellow.

(2) Improper watering Asparagus likes humidity, but it is afraid of waterlogging. Sandy soil should be cultivated actively to make it breathable and permeable.

(3) Insufficient fertilization I don't like fat asparagus. Fat is easier to pump out, but it can't be used as long-term fertilization, which will also lead to the lack of nutrients. Water it once, decompose the thin fertilizer every six months, and pay attention to watering and fertilizing in time to loosen it.

(4) Improper fertilization is suitable for thick raw fertilizer or chemical fertilizer, which will send the leaves away. It is necessary to dilute the washbasin with water in time, or change the soil immediately for preservation.

(5) In winter, the pipe should be placed in the space with poor sunshine and temperature of 8- 12 degrees. Long-term shading, the temperature below 8 degrees, will lead to yellow leaves.

(6) Asparagus is polluted by smoke and dust, so it should be put in place to protect air circulation and avoid pollution. Foliar spraying should be multi-directional to wash dust.

Supplement:

Green asparagus, like a blue overlap, is quiet and beautiful. Zhu Wu, whose real name is Aspartame, has green and long branches, which fills the gap in China. Asparagus, the genus Asparagus in Liliaceae, is a perennial herbaceous flower for nearly a hundred years. It is native to southern African countries and cherished by the people. Every household puts it on the table in the bedroom. Corsage, basket and bouquet, two important bamboo or flower materials, are widely used to set off the art of flower arrangement and make it more beautiful.

Asparagus has semi-fleshy roots and thin stems, and climbs 2-3 meters. The stems and leaves degenerate into scales, and the apex is prickly; The so-called abnormal leaf branch is actually a part of it. Combine each side branch with pinnate compound leaves and elegant clouds. Flowers are small, white, small spherical berries, and seeds are black. The main variety is low-key asparagus, with short and erect stems, weak or unstretched vines, dense and short branches and many leaves.

Asparagus likes mild climate and is not cold-resistant, heat-resistant and drought-resistant. The basin must be kept moist, and the environment should also be kept moist. Avoid floods. I am afraid of the sun in spring, summer and autumn, and indoor lighting should be scattered in winter. Potted soil requires rich humus, drainage and breathable sand for cultivation. Usually sow and reproduce. Breeding by dividing plants, large plants are easy to change color, and the strong survive. The seeds matured from1February to April, and the seedlings were planted in a sand basin with a spacing of 1-2 cm, and the covering layer was as thick as a seed. Sow the seeds, cover the glass, then cover the newspaper and pour water, so that a lot of indoor lighting and air circulation can be realized at about 20℃. After 30-40 days, the seedlings go out together, remove the cover and put the diffused light there. When the seedlings are covered with pots, they can be planted separately. When the seedlings are destroyed, the whole group is broken, and two or three trumpet pots are used for ordinary potted plants or pure sand is added to the decomposed farmyard manure. One plant in each pot should be transplanted and sprayed and watered the next day. After the temperature rises in late spring, it should be stored outdoors in a cool place. In a cool and humid environment, dilute liquid fertilizer can be applied once every 10 day. The early-sown pipe jacking basin can also be switched between August and July, and 20 grams of shoes can be placed under it, so that/kloc-0 can enter the room at the beginning of October, making a plump tree for the new year.

With asparagus seeds as the mother plant, the plant must close the large flowerpot that has been stable for two years, choose a corner of the greenhouse for planting, use loose and fertile soil as the base fertilizer shoes, and make the vertical stems elongate for climbing. Management should be meticulous, fat should be appropriate, and flowers should be seen in July. Inject fresh air for circulation, moderately control the amount of water to prevent falling. In the greenhouse, a net curtain is placed above the high temperature season to shade the sun, and the front and rear doors and windows are opened to cool down as a whole to ensure seed harvest.
