Wind protection is umbrella plant, sweet and warm. There is a solution, dehumidification, and pain relief. Indications cold cold, headache, fever, joint pain, quadriplegia, tetanus and so on. Morphological characteristics Windbreak is a perennial herb, plant height 30-100 cm, the body hairless. Its main root is long and thick, with a pale brown surface and scattered lenticels. Brown fibrous petiole residues densely arranged on rhizomes. Umbrella inflorescence, umbrella spokes 5-7. White flowers. The double-hanging fruit is ovoid, and the mature fruit is yellow-green or dark-yellow. The young fruit has a verrucous protrusion on the surface. There are 5 edges. Flowering is from August to September. Biological characteristics Strong wind adaptability, like warm, cool climate conditions, cold, drought, fear of high humidity, avoid rain, poor growth in humid areas, joy in the grasslands, hillsides and woodlands, suitable for birth in Deep sandy soil, loose soil, fertile, well-drained sandy loam. It can be cultivated in northern China and the Yangtze River basin. Windbreak seeds are easy to germinate and germinate at 15°C-25°C. The germination rate of fresh seeds is between 75% and 80%. The germination rate of seeds stored for more than 1 year is significantly reduced. Therefore, it is better to use fresh seeds as seeds for production. The suitable temperature for windproofing is 15°C. The selection of land and wind protection is a deep-rooted plant. The main root is 50-60 cm in length and should be planted in a land of high-dryness and well-drained sandy soil. Windbreaks planted on clay have very short roots, multiple bifurcations, and poor quality. Wind protection is a perennial plant. It is necessary to apply enough basic fertilizer for site preparation. 3000-4000 kg per mu and 15-20 kg of superphosphate are used for deep plowing. In northern China, it can be made into a 1.3-1.7-meter-wide bunting. In southern China's rainy regions, it can be made into a 1.3-meter-wide bun with a ditch depth of 25 cm. Breeding method Wind protection is based on seed reproduction, but it can also be divided and rooted. First, seeds can be sowed in spring and autumn. Spring sowing time, the Yangtze River Valley in late March to mid-April, North China in mid-April; autumn sowing time, the Yangtze River Valley in September-October, North China before the planting in the ground, the second spring emergence. In spring sowing, the seeds should be soaked in warm water for 1 day to make them fully absorb water to facilitate germination. Then, in the entire well, press the 30-40 cm line spacing to drill the ditch, soak the ditch 2 centimeters in depth, then spread the seeds evenly into the ditch, cover the soil and level it, put a little pressure on the grass, cover the grass and water to keep the soil moist. Use 2-3 kg per acre. Second, rooted in the wind breeding harvest, select more than two years, robust growth, crude 0.7 cm or more, no pests and roots, cut into small pieces of 3-5 cm long for planting. According to the spacing of 50 cm, 10-15 cm spacing planting holes, planting depth of 6-7 cm, planting 1 root per hole, after planting soil cover 3-5 cm thick, or in the winter will be based on 10 cm 15 cm Lines, spacing, nursery, when the next spring there are 1-2 leaves when the planting. When planting, care should be taken to remove the germinating seedlings. The amount of roots per acre is about 50 kilograms. Four managements: one seedling, one seedling, one seedling, and five seedlings when the seedling height is 5-6 cm. When the first true leaf appears in the plant, the seedlings are 6-7 cm in spacing; when the seedling height is 10-12 cm, press 13-16 cm. Plant spacing Dingmiao. When the seedlings are found, if they are found to be seedlings, the seedlings shall be promptly filled. Second, weeding and weeding will be repeated several times in June. Weeding once when thinning. When cultivating seedlings, one cultivator is conducted and the cultivator is 2-3 times in the following year. When the plant height is about 30 cm, the old leaves are removed first, and then the roots are plucked to prevent their lodging. In the winter, we combine cleanup of field weeds, old leaves, and earthing again. Third, top dressing fertilizer 3 times. For the first time in the period of seedlings, 1,000 kilograms of human fecal urine was applied per acre and lightly poured between the rows. The second time after Dingmiao, apply 10-15 kg of urea per acre. The third time in late August, 25 kg of calcium phosphate was applied per acre. Fourth, snoring For plants more than two years old, in the June-July convulsions and flowering, in addition to leaving the species, when the calyx should be promptly removed. 5. Drainage and Irrigation should keep the soil moist before sowing or planting until emergence. Strong wind and drought resistance, no irrigation. The rainy season should be drained in time to prevent the accumulation of water. Diseases and Insect Pests Prevention and control of wind common pests include powdery mildew, root rot, spot blight, yellow butterfly, yellow winged fennel and carrot microtubules. First, powdery mildew The disease occurred in summer and autumn, mainly damage the leaves. Prevention methods are: pay attention to ventilation and light, increase phosphorus, potassium fertilizer. Onset of spraying with 50% thiophanate-methyl 800-1000 times spray control. Second, the root rot disease occurs in the high temperature and rainy season, the main damage to the roots. Control methods: First, in the early stages of disease, remove the diseased plants in time, and disinfect the disease points with lime powder. The second is to rule out the accumulation of water in the field. The third is to carry out ridging planting on the low ground. Third, spot blotch, also known as leaf spot disease, mainly damages the leaves. Control methods: In the early stage of disease, remove diseased leaves and spray 1:1:100 Bordeaux mixture 1-2 times. After harvesting, remove the diseased tissue and centrally burn it. Fourth, the yellow phoenix butterfly insect damage occurs in May. Larvae mainly eat leaves and buds. Control methods: Spray 90% crystal trichlorfon 800 times in the young stage of insect pests, or carry out manual killing. Five, yellow winged fennel worm damage occurs in the bud flowering period. The larvae form a net on the flower buds and take flowers and fruits. Control methods: Use 90% crystal trichlorfon 800 times in the morning or evening, or use 300 times Bt emulsion spray control. Sixth, carrot microtubules This pest damage occurred in May-June, the main harm windproof shoots. Control methods: In the insect pests, spray 50% Caesarean Pine 1000-2000 times, or use 40% Dimethoate 1500-2000 times, spray once every 7-10 days, and spray several times. Harvesting The winter season is harvested before sprouting from late October to mid-November or spring. Breeding with seeds, windproof, can be harvested the next year. In spring, the wind and roots can be harvested in the same year when the water and fertilizer are sufficient and the growth is lush. When the root length is 30 centimeters long and 1.5 centimeters thick, it can be harvested. Autumn harvest is harvested from October to November in the following year. When harvesting, deep trenches shall be opened from one end of the raft, excavated in order, and the remaining stems and soil shall be removed after the roots are dug out. Each mu can receive 150-300 kg of dry goods. Keep seedlings selected for the two-year-old plants that grow vigorously and have no pests and diseases. Apply phosphate fertilizer to promote flowering and fruiting. After the seed matures, the stems are cut off and the seeds are immersed. After the seeds are dried, they are kept in a cool place. When harvesting, roots with a length of 0.7 cm or more are selected as seeding roots. Such as spring transplanting, planting use. China Agricultural Network Editor
