The stem of asparagus is climbing. If it is allowed to grow, it will lose its lightness if it can reach several meters high. Measures to shorten asparagus are:
1. For seedlings, it is not allowed to apply more fertilizer in spring and summer when they grow vigorously, but only once a month. The amount of fertilization should not be too large, and the principle of light should be mastered. For old plants, it is best to apply little or no chemical fertilizer, just use the opportunity of changing pots to fill the bottom of pots with fresh soil or apply a little fertilizer. In this way, both young and old plants can maintain a stable growth potential.
2. Pay attention to frequent pruning. Asparagus grows fast, so it is necessary to trim the old branches and dry stems at any time and keep the posture of low bottom. At the same time, cut off the trailing branches in time to keep them tall, beautiful and lush and green.
3. Selection of dwarf asparagus varieties. Short asparagus stems have no tendrils and can be kept small and exquisite.
[Edit this paragraph] Pest control
Asparagus is a perennial green herbaceous flower, which is called yunzhu, Songshan grass and Yunzhushan grass in some places. Although asparagus has the characteristics of evergreen for many years, if it is not properly maintained, it will often appear the symptoms of yellowing of branches and leaves, which will affect the ornamental effect.
Why do bamboo leaves produce symptoms of yellowing? According to the author's practice of preserving asparagus, the original text; There are probably the following reasons: first, if asparagus is left by the fire for a long time, not only will the feathers of the whole branch turn yellow and fall off, but the stem will also dry up. Second, asparagus will gradually dry up when it is placed next to the TV. Third, exposed to strong light for a long time, plants first stagnate, and then their leaves turn yellow. Fourth, neglect watering, or only watering the surface pot soil, the roots did not absorb enough water, and the stems and leaves slowly turned yellow. Fifth, excessive watering leads to root rot, and then stems and leaves wither. Sixth, improper fertilization, high concentration or immature fertilizer application will easily dry up when using the seedling burning machine, and will also lose fertilizer and turn yellow if it is not topdressing for a long time. Seventh, plants will grow weak and turn yellow if they are placed in a cool environment for a long time. Eight is suffering from freezing injury, which leads to yellowing of branches and leaves.
In order to keep asparagus fresh and beautiful, the following measures should be taken to prevent the stems and leaves from turning yellow:
First, adjust the fertilizer and water. During the growth of bamboo in the Art Troupe, it is not necessary to fertilize too frequently. Generally, it is only suitable for topdressing in spring and autumn, and dilute decomposed manure or low-concentration compound fertilizer solution, or rice washing water and bean juice water are applied every 18 ~ 15 days. High temperature in summer and low temperature in winter are not suitable for fertilization. Fertilization should be controlled not too much or too late. Water without watering. When it is dry, water it thoroughly at one time, and don't leave waterlogging on the basin surface. Dust on the leaf surface should be sprayed regularly to remove dust.
Second, proper placement. Asparagus likes semi-cloudy, semi-sunny and slightly wet environments. First, avoid exposure to the sun, but where you can see the sun; Second, you should be able to feel the air circulation; Third, stay away from stoves and televisions; Fourth, keep warm, and the room temperature should not be lower than 5℃. If the room temperature is between 0℃ and 4℃, cover it with plastic to keep out the cold.
Third, plastic surgery in time. Asparagus tends to clump. First, when changing pots and covering soil, it is necessary to trim old and residual fibrous roots and redundant stems and leaves to avoid excessive consumption of nutrients, so as to support roots and protect leaves; The second is to cut off the partially yellow leaves; The third is to cut off the stems and leaves that are yellow at the same time.
[Edit this paragraph] The reason why asparagus leaves turn yellow:
(1) Too strong light and direct sunlight can easily cause the leaves to turn yellow.
(2) Improper watering Asparagus likes humidity but is afraid of waterlogging, so it should be cultivated in breathable and permeable sandy soil.
(3) Asparagus doesn't like fertilizer if it is not fertilized for a long time, and it is easy to peel if it is fertilized for a long time, but it will also cause insufficient nutrients. Should be watered once every half month, pay attention to watering and loosening the soil in time after fertilization.
(4) Improper fertilization, such as applying original fertilizer or excessive fertilization, will make the leaves fall off. At this time, the basin soil should be washed and diluted with water in time, or the soil should be changed immediately for preservation.
(5) The winter pipeline with poor winter should be placed in a sunny place indoors, and the room temperature should be kept within 8- 12 degrees. Long-term shady, room temperature below 8 degrees, will lead to yellowing of leaves.
(6) Asparagus polluted by smoke is most afraid of smoke and harmful gases, so it should be maintained in a place with good air circulation to avoid pollution. You should also spray water on the leaves to wash away the dust.
[Edit this paragraph] Zhu Wen Wuzhu
Asparagus is lush, like blue clouds overlapping, quiet and beautiful. Black bamboo, whose real name is Asparagus, has soft branches and green leaves, which lead vines to stretch like running water. Asparagus and Phyllostachys pubescens are perennial herbaceous flowers of Asparagus in Liliaceae, which are native to southern Africa and have a history of nearly 100 years in China. They are cherished by China people, entered thousands of households and placed in their rooms. Erzhu is also an important material for flower arrangement, and lapels, flower baskets and bouquets are widely used, which set off artistic flower arrangement and make it more beautiful.
Asparagus roots are semi-fleshy, and slender stems climb 2 to 3 meters. Leaves degenerate into scales with stalks, and the apex is prickly; The leaf is actually a perverted branch. Each lateral branch is pinnately flat, forming an elegant cloud. The flowers are small and white, the berries are spherical and the seeds are black. The main variety is dwarf asparagus, with short and upright stems, weak or no vines and dense and short leafy branches.
Asparagus likes mild climate, not cold and heat resistant, and avoids drought. The basin soil needs to be moist, and the environment should also be moist. Avoid floods. I am afraid of the scorching sun in spring, summer and autumn, and the indoor light will be scattered in winter. Potted soil requires sandy culture soil with rich humus and strong drainage and air permeability. Usually sow and reproduce. Breeding by dividing plants, big plants are not easy to grow strong and survive. The seeds mature from February to April of the following year, and can be planted with sand in the nursery basin with the spacing of 1 to 2 cm. Covering soil is equivalent to 1 seed thickness. After sowing, water it, cover it with glass, cover it with newspaper and put it in a well-lit and ventilated room at about 20℃. After 30 to 40 days, remove the cover and put it in a diffuse light place. When the seedlings are full, they can be planted separately. Knock out the whole seedling, break it, add 20% decomposed manure with ordinary culture soil or plain sand, and put it into No.2 or No.3 cylinder basin. One plant in each pot should be sprayed with water after planting and watered the next day. After the end of spring, as the temperature rises, it should be maintained in the shade outside. Pay attention to keep the environment fresh and moist, and apply dilute liquid fertilizer every 10 day. Early sowing can be formed in July, or the first pot can be changed in August, and 20 grams of hoof pad can be used as the base fertilizer. In early June, 65438+ 10 will enter the house, and plump plants will grow on New Year's Day.
To collect the seed asparagus mother plant, it is necessary to take the 2-year-old strong big plant out of the pot and plant it in a corner of the greenhouse. The soil should be loose and fertile, and the hoof can be used as base fertilizer to make the branches and leaves stretch and climb. Management should be meticulous, water and fertilizer should be moderate, and flowers will begin to bloom in July. Pay attention to fresh air circulation during flowering period, moderately control the amount of water to prevent falling flowers. In high temperature season, the greenhouse should be shaded by curtains, and all the front and rear doors and windows should be opened to cool down to ensure the mature harvest of seeds.
Zhu Wu Cordyceps sinensis has small fleshy roots, long drooping stems, up to 1 m long, dense branches and luxuriant leaves, small white flowers, round fruits, from green to white, and bright red at maturity.
Wu Zhu likes sunshine and is slightly tolerant of shade. Usually propagated by seeds and matured in 65438+February. After picking, rinse with water, mix with plain sand and common culture soil evenly, put in a seedling pot, water and plant, with a spacing of 2 cm and a thickness of two seeds covered with soil. Cover with glass, cover with a layer of newspaper, and store in a sunny place at 20℃, and the seedlings will come out in about 30 days. Gradually uncover the cover, and when the seedlings are 2 to 3 cm high, pour a dilute liquid fertilizer. When the seedlings are full of pots, take out the whole lump and divide the seedlings into pots. Ordinary culture soil can be placed on the head with 3 ~ 4 trumpet pots, with even spacing, and can be maintained in the open air after mid-April. Apply liquid fertilizer every 10 day. Organic fertilizer and chemical fertilizer can be applied alternately, or with fertilized culture soil, 50 grams of hoof pieces are placed below, and two tanks and pots are changed for maintenance, and the "Eleventh" will become a big plant.
Asparagus should be changed once a year, increasing year by year. If the big pot is not replaced, some small roots can be removed by turning over the pot, replacing new soil, planting in the original pot, paying attention to updating the stems and branches at ordinary times, and removing the old and sick stems and branches at any time.
