Wind protection is an umbrella plant of the Umbelliferaceae, which uses root medicine. Sweet, spicy, warm. There are solutions, hurricane dampness and other functions. Treatment of cold, cold, headache, fever, no sweat, joint pain, rheumatism, pain, limb paralysis, skin itching embolism. It is mainly produced in Heilongjiang, Jilin, Liaoning, Hebei, Inner Mongolia and Shandong, and Heilongjiang producers are preferred.

Windproof hi Sunny, cool climate conditions, avoid high temperature, rain and soil moisture, more cold, drought. In the aeolian sandy soil, meadow sand, and grassland, chernozem cultivation has a well-developed main root, less lateral roots, brownish brown skin, and good product quality.
First, breeding seedlings can be propagated by seeds and roots, and seeds are usually used for production. Spring, summer and autumn can be planted, but sowing in dry areas, the general emergence rate and seedling maintenance rate is low. Knowing the right seeding time and sowing method is the key to keeping seedlings. The spring sowing period is long and the yield is high, but it needs to be sown by irrigation or by sowing, and timely cover the agricultural film. Seed sowing after summer rain is good for seedlings and seedlings, and can also cover agricultural film. After the cover film is pressed, a small pile of soil is pressed to prevent the agricultural film from being blown off by the wind. Immediately after emergence, the membrane is released to cool and the seedlings will be burned if the membrane is broken too late.
Planting sites should be selected as high-desert, sunny, well-drained, deep soil plots. Planting roots in clay are short, bifurcated and of poor quality. Planted fields can be used as wasteland or wasteland, and seed fields can be used as rehabilitated land. Before the preparation of the basal fertilization, peasant fertilizers of 3,000 to 5,000 kilograms per 667 square meters are used. Attention should be paid to cultivating and cultivating. Irrigation conditions can be used to make rakes, which are about 1.3 meters wide.
Before sowing, soak the seeds in fresh water for 1 day, remove them, cover them with damp cloth or sacks, keep them moist, and sow the seeds when they start sprouting. Grooves at 30 cm spacing, 2 cm deep. For every 667 square meters, 1 to 2 kilograms of seeds will be used to sow the seed evenly into the ditch, covering the earth with a cover, and suppressing it slightly to cover the grass or cover the film to keep the soil moist.
It is also possible to use the method of root-reproduction. When harvesting herbs in autumn or early spring, roots with a length of more than 0.7 cm should be taken and cut into root segments of 3 to 5 cm in length, with a spacing of 50 cm and a spacing of 15 cm. ~ 8cm, each hole vertically or inclined into a root segment, covering the earth 3 to 5 cm, pay attention to the root up. Roots can also be planted in a greenhouse in the winter at a spacing of 10 cm and 5 cm from the planter. In the second year of early spring, when 1 or 2 leaves are transplanted, the non-germinating roots cannot be planted. The vegetative propagation has a high seedling retention rate.
Second, cultivation management
1. The seedlings are divided into two seedlings. When the seedling height is 5 cm, the seedlings are 7 cm in spacing from the seedlings; when the seedling height is 10 cm, the seedlings are 15 cm in spacing from the plants.
2. Weeding earth should be promptly removed weeds. When the plants are sealed, the old leaves can be removed and the roots can be cut in order to maintain the ventilation and prevent the lodging. Combine the fields before going to the winter to clean up and cultivate the soil to protect the roots from wintering.
3. Top dressing In early June and late August, each top dressing was used once. DAP and compost can be used to apply ditching between rows.
4. Picking up the two-year-old non-leaving farmland and finding that the calyx is removed in time, otherwise it is easy to consume nutrients that affect the development of the roots, resulting in lignification of roots and loss of medicinal value.
5. Drainage and sowing Before sowing or planting until emergence, we should keep the soil moist and promote the emergence of seedlings. When the seedling height is 10 to 15 cm, the drought resistance is strengthened, and it is generally not necessary to water during growth. In the rainy season, attention should be paid to timely drainage to prevent the accumulation of water and rot.
6. Diseases and Insect Pests Prevention and treatment of powdery mildew and leaf blight in summer and autumn. Pay attention to timely ventilation, increase phosphorus, potassium fertilizer. Before the onset of the disease, 0.3 Baume degree lime sulfur spray, 50% thiophanate-methyl wettable powder 600 to 800 times and 70% mancozeb manganese or 77% to kill 500 times, etc., are used alternately every 10 days 1 Times, spray 2 or 3 times.
Third, harvest and processing
It is harvested before sprouting in late October, mid-November or spring. Breeding with roots and windbreaks, the water and fertilizer conditions can be harvested in a year. The general two-year harvest of seed reproduction. After the root is dug up, the residual stems and leaves and the soil are removed. When the skin is dried to the half dry state, the hairs are removed, and the sun is dried until it reaches 99% dry. The roots are roughly shorn and short and the bundles are bundled into about 1 kg weight and continue to be dried. Dry or dry. In general, 250 to 350 kg of dry goods can be collected per 667 square meters, and the dry rate is about 25%.
The goods are divided into two classes: one is in a cylindrical shape, 15 cm in length and 0.6 cm in diameter in the reed. The second-class roots have branches, the reed diameter is more than 0.4 cm, and the rest are the same. Thickness of the roots, fine and tight skin, light brown cross-section leather, light yellow wood quality as well.
