How to manage planting Angelica sinensis?
How to manage planting Angelica sinensis? Please guide the planting of Angelica sinensis with reference to the following methods: 1. When the seedling height is 3 cm, the first seedling is carried out, and then the second seedling is carried out half a month later. When the height of the seedling is 10 cm, fix the seedling. There were 2 or 3 strong seedlings in each hole. 2. Intermediate ploughing and weeding Angelica sinensis 1. When the height of interseedling and fixed seedling is 3 cm, the first seedling is carried out, and the second seedling is carried out half a month later. When the height of the seedling is 10 cm, fix the seedling. There were 2 or 3 strong seedlings in each hole. 2. Angelica sinensis grows slowly at the initial stage of seedling emergence, but weeds grow rapidly, so weeds should be weeded in time, from seedling emergence to ridge closure, weeding should be done for 3 or 4 times by stages. The first weeding was carried out when the seedling height was about 5 cm, the second time after the seedling was fixed, and the third time before the seedling height was 20-25 cm. Combine weeding to loosen the soil to prevent soil consolidation, improve ventilation, moisture and temperature conditions, and promote root development. Weeding should grasp the principle of "deep in the middle and shallow at both ends", that is, young seedlings and the Beginning of Autumn should not be hoed deeply. Because the root system of Angelica sinensis after the Beginning of Autumn has been enlarged and rich in sugar, it is easy to cause rotten roots once damaged. At this time, if there are weeds, they should be pulled out in time. 3. Topdressing Angelica sinensis needs more fertilizer in its lifetime. 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 period of root growth in August, which are the two peak periods of fertilizer demand. The amount of topdressing should be greater in the root growth period than in the leaf growth period and returning to green stage. Potassium dihydrogen phosphate, diammonium phosphate and nitrogen, phosphorus and potassium compound fertilizer are usually used as topdressing. 4. in the early growth stage of drainage and irrigation, watering is generally controlled except for proper watering during drought. Rain Water is too much, it is necessary to timely dredge ditches and drainage, especially in the late growth stage, the field can not accumulate water, otherwise it is easy to cause rotten roots. 5. Angelica sinensis grew to the middle and later stage (after August), the root system began to develop and grew rapidly. At this time, soil cultivation can promote the development of roots and help to improve yield and quality. Soil cultivation can be combined with loosening soil.

How many methods are there for breeding Angelica sinensis? Please introduce Angelica to propagate with seeds, generally using the method of raising seedlings and transplanting, or direct seeding. 1. Seedling transplanting (1) selected seeds: the yield of Angelica sinensis seeds is 14.6 kg higher than that of unselected seeds per mu. The main method of selection is ear selection. When Chinese angelica is harvested, when it is planted.
