Windproof is a familiar Chinese herbal medicine. It has the effects of hurricane solution, Shengshuo pain, and phlegm. It is widely used in our medicine. In recent years, with the fiery heat of Chinese herbal medicines, the number of wind-proof planters has also increased. However, the wind has its own attributes, and it is necessary to know the professional planting techniques to make money and profit. Therefore, the popularization of high-quality cultivation techniques for wind protection is particularly important.

1 Site preparation

Wind-resistant adaptability and resistance are strong, and have certain resistance to cold and drought, but prefer a sunny, cool environment and well-drained sandy soil. In addition, the windproof is a deep-rooted plant with a root length of 50 to 60 cm. Therefore, in order to obtain high-quality and high-yield windproof, we should choose a sunny block with convenient drainage, deep soil layer and dry environment.

After selecting the plot, you can carry out the land preparation. The first is deep ploughing. The wind is a perennial plant with a long root and a depth of 40 cm or more. After the tillage, the base fertilizer is applied. The base fertilizer is mainly composed of decomposed farm organic fertilizer, and the applied amount is 3,000 to 4 000 kg/667 m 2 . In order to promote wind-proof growth, 15 to 25 kg/667 m 2 of urea can be added to the base fertilizer. . After applying the base fertilizer, the plot is flattened. If the plot is relatively low, you can ridge and dig the trench.

2 Ways of reproduction

The main methods of breeding for wind protection are seeding and rooting. The sowing and breeding can be carried out live, and can be transplanted. The breeding methods are described separately below.

2.1 Sowing and breeding

Sowing and breeding is the main breeding method for wind protection. Sowing can be carried out in spring and autumn, and spring sowing is generally carried out from mid-April to early May. Autumn sowing is generally carried out before the soil is frozen, and emerges in the spring of next year. It takes a long time for the wind-proof seeds to germinate, generally takes 30 to 45 days, and the seedlings are not uniform. Therefore, it is generally necessary to carry out seed soaking and germination before sowing. Especially when it is necessary to plant seedlings as soon as possible in spring, it is generally necessary to soak seeds in warm water of 30-40 °C for about 24 hours, so that the seeds fully absorb water and promote their germination. While soaking seeds, the seeds floating on the surface of the water are removed, which can increase the germination rate of the seeds.

Although the wind-proof sowing and breeding can be broadcasted live or transplanted, it is found in practice that the first year of sowing, the next year's transplanted wind can make full use of the seeds, and the quality of the medicine is higher. During the live broadcast, ditch the ditch in the whole raft with a line spacing of 30~40 cm, the ditch depth is 2 cm, then spread the seeds evenly into the ditch, cover the fine soil leveling, slightly suppress, if it is drought, it should be timely Irrigation to keep the soil moist, the seeding rate is 2 ~ 3 kg / 667 m 2 . When raising seedlings, it is made of 1.2 m wide and 15 to 25 cm high. The length of the clam is generally determined by the terrain conditions, so that management is the principle. The trampoline is required to be flat, straight and solid. Spread the seeds evenly on the surface of the clams, cover the soil with a thickness of about 2 cm, compact and cover the grass, which is conducive to the emergence of seedlings. In case of continuous dry weather, it should be watered in time, and the seeding amount is 15-20 kg/667 m 2 .

2.2 Root propagation

After the completion of the site preparation, the hole spacing is about 50 cm, and the plant spacing is 10-15 cm. When harvesting windproof, the robust root strips with a growth time of more than two years and a diameter of 0.5-0.7 cm can be cut into small sections of 3 to 5 cm long, one for each hole, and then 3 to 5 cm of soil. The use of root-propagated windproof not only grows faster, but also the planting process is simple and quick, saving seeds and planting in large areas.

3 Field management

3.1 Seedling management

When starting seed germination, water it in time to keep the soil moist. However, it is not possible to water too much to cause the soil to agglomerate. The first weeding was carried out after the seedlings were released; when the seedlings were grown to 6-8 cm, the second weeding was carried out. At the same time, the first top dressing was carried out, and the urea was applied 1.5-2 kg/667 m 2 . Apply urea once every 3 weeks and apply it 3 times.

3.2 between seedlings, seedlings, and seedlings

If it is live, after the seedlings are out, it is necessary to carry out the seedlings, make up the seedlings, and fix the seedlings. Generally, when the seedlings grow to 6-8 cm, the seedlings are firstly planted, and the plant spacing is maintained at 7-8 cm. At the same time, weeding is carried out, and then fertilization is carried out. When the seedlings grow to 10 to 12 cm, the seedlings are fixed, and the plant spacing is maintained at 15 to 18 cm. At the same time, if the plant spacing is too large due to non-germination, it is necessary to transplant the seedlings of other areas in time or replant in time.

3.3 Transplanting and planting

After the good plot, the decomposed farm organic fertilizer is applied 3 000 ~ 4 000 kg / 667 m 2 , urea 10 kg / 667 m 2 , superphosphate 12 ~ 15 kg / 667 m 2 . Then use a plow to open the ditch, keeping the plant spacing 12-15 cm, the row spacing 45-50 cm, and the density of 6 000-8 000 plants/667 m 2 . The seedlings are placed obliquely in the furrow, and the seedlings are slightly pressed into the soil from the bottom to the top. The top of the seedlings is 3 to 4 cm from the ground, and the ground is leveled after the planting.

3.4 Topdressing and cultivating

In May-June, due to more rainfall and higher temperatures, weeds grow faster, and seedlings grow faster, requiring adequate nutrients. Therefore, it is necessary to timely topdress and cultivate weeding. According to the growth of weeds, weeding is generally carried out once every 3 to 4 weeks. Fertilization is carried out at the same time as cultivating and weeding, with 10 to 15 kg/667 m 2 of urea and 20 to 25 kg/667 m 2 of superphosphate.

3.5 Pest Control

Common diseases of wind protection include powdery mildew, root rot, spot blotch, etc. The insect pests include yellow swallowtail butterfly, yellow-winged fennel and carrot microtubules. In order to improve its quality, physical and biological control technologies should be the mainstay. The first is to cultivate strong seedlings through reasonable fertilizer management, and reduce the occurrence of pests and diseases; secondly, cultivate natural enemies of pests, such as Trichogramma, etc., to reduce the population of pests; again, through pesticide control, diligent observation, once pests and diseases are found The trend is to use targeted pesticide prevention immediately to reduce losses due to the occurrence of pests and diseases.

4 harvesting

Windbreaks generally have to grow for more than 3 years to have good quality before they can be harvested. It is generally harvested in both spring and autumn, and the spring harvest is carried out before the germination; the autumn harvest is partially killed in the ground, but the land has not been frozen before. If the area is large, mechanical harvesting can be used. The wind-proof root is long and the harvestable part can reach 30-40 cm. Remove the stems, leaves and soil after excavation, generally harvest windproof 150 ~ 300 kg / 667 m 2 .

The above is the high-quality and high-yield cultivation technology of the wind-proof series compiled by Huinong. Have you learned it? As an important Chinese herbal medicine, wind protection has a broad prospect for planting, but growers must master the cultivation techniques.
