阶段二是移栽之后的大田管理。一般而言，涉及下面主要内容，第一，补苗和间

The second stage is field management after transplanting. Generally speaking, the following main contents are involved. First, replenishing seedlings and thinning. After transplanting is completed, because the local nutrient characteristics of the plot are different, the seedlings will grow or fail to grow. Therefore, timely thinning or replenishment is required. , Weeding and top dressing, weeding can be implemented with herbicides or combined with agricultural film mulching; fertilization generally adopts the method of ring application, applying "eccentric fertilizer", and the third is irrigation or drainage management. The water source conditions of special plots are different. Whether it is drought or flooding, prompt treatment is required. The fourth content is the extraction and drying of mature medicinal materials. After the specific growth period reaches the standard, harvest or excavate the medicine parts in time according to the requirements of the pharmacopoeia, and dry it in a suitable way after preliminary washing with clear water and enter the transportation link.

Stage two is the management of the field after the transplant. Generally speaking, involving the following main content, first, seedling and inter-seeding, after transplanting, because the local area of the plot nutrient characteristics are not the same will lead to seedlings grow or can not grow, so to timely between seedlings or seedlings, second, weeding and fertilization, Weeding can be implemented with herbicides or in combination with the cover of agricultural film, fertilization is generally done by ring application, "eccentric fertilizer", third, irrigation or drainage management, special land water conditions are not the same, whether drought or flooding requires timely treatment, The fourth content is the extraction and drying of mature herbs. After the specific reproductive period has reached the standard, according to the requirements of the Pharmacopoeia timely collection or extraction of the drug site, with water after the initial cleaning using a suitable way to dry into the transport link.

The second stage is field management after transplanting. Generally speaking, the following main contents are involved: first, supplementary seedlings and thinning seedlings. After transplanting, due to the different nutrient characteristics in local areas of the plot, the seedlings will grow rapidly or fail to grow. Therefore, timely thinning or replenishing seedlings should be carried out. Second, weeding and topdressing can be carried out with herbicides or combined with mulching of agricultural film. Fertilization generally adopts the method of ring application, with "eccentric" application The third is irrigation or drainage management. The water source conditions of special plots are different. Whether it is drought or flooding, timely treatment is required. The fourth content is the excavation and drying of mature medicinal materials. After reaching the standard in the specific growth period, the drug parts should be collected or dug in time according to the requirements of Pharmacopoeia. After preliminary cleaning with water, the drug parts should be dried in proper way to enter the transportation link.<br>
