Planting technique of Angelica sinensis

Angelica sinensis planting should first choose a good planting site, and then soil preparation and fertilization. Then sow the prepared seeds and raise the seedlings, and after the seedlings are finished, the seedlings can be raised and transplanted. Attention should be paid to checking and replenishing seedlings after transplanting. Finally, do a good job in field management, such as weeding and loosening soil, topdressing, drainage and irrigation and pest control and so on.

Field management of Angelica sinensis:

1. Check seedlings and replenish seedlings: Angelica can emerge one after another about 20 days after transplanting. If there is a shortage of seedlings, they should be replanted in time.

two。 Weeding and loosening soil: weeding is carried out for the first time when the seedling height is about 5 cm. From emergence to sealing, weeding should be done 3-4 times in stages, combined with weeding to loosen the soil to prevent soil consolidation.

3. Topdressing: Angelica needs more fertilizer in its life. In addition to applying sufficient base fertilizer, it should also be applied in time. The suitable time for topdressing is the peak period of leaf growth in late June and the root growth period in early August. There is a general shortage of phosphorus and potassium in the soil of Angelica sinensis producing area and farm fertilizer, so it needs to be filled with phosphorus and potassium fertilizer. Potassium dihydrogen phosphate, diammonium phosphate and nitrogen, phosphorus and potassium compound fertilizer are usually used as topdressing.

4. Irrigation and drainage: Angelica needs a moist soil environment for growth, and proper irrigation during drought is beneficial to high yield. Rain Water should pay attention to trenching and drainage when there is too much, especially in the later stage of growth, the field can not accumulate water, otherwise it will cause root rot and cause root rot.

5. Cultivate the soil: Angelica grows to the middle and later stage (after August), the root system begins to develop and grows rapidly. At this time, soil cultivation can promote the development of body return and help to improve the yield and quality. Soil cultivation can be combined with loosening soil.

6. Beating old leaves: after angelica is closed, the lower old leaves turn yellow due to lack of light, and these old leaves should be removed in time, which can not only avoid unnecessary nutrient consumption, but also improve the ventilation and light transmission conditions within the population.

7. Timely extraction of moss: early bolting plants, the roots gradually lignified, become firewood roots, losing medicinal value. This kind of plant has strong vitality and consumes a lot of water and fertilizer, so it should be pulled out in time so as not to consume soil fertility and affect the growth of unbolted plants.

Angelica has been planted in our country for a long time, and the planting technology is relatively mature. Friends who have ideas can consider it.
