Cultivation techniques of Angelica sinensis

Angelica sinensis is propagated by transplanting with seeds. The harvest in the second year of autumn direct seeding or the harvest of spring direct seeding in the same year were also found in lower altitude areas (1500-1800 m), but the yield and quality were low.

Choose cool and moist Yinshan or Eryin Mountain, potholes and small basins that conserve water but do not accumulate water, instead of dry wind beams. Soil quality requires loose and fertile, there is no stone large black soil or black oil sand, generally choose wasteland to raise seedlings. Make a 1-meter-wide high border on the leveled land, sow the seeds evenly on the border surface while it is wet in mid-late June, cover the soil strictly, step on the foot again, and then hold it flat with an iron rake. In order to conserve soil moisture, cover the border with firewood and grass about 3.3 cm thick. After all the seedlings come out, there should be seedlings in places where they are too dense. Cold Dew dug up the seedlings before and after and stored them in a cool and dry place. After thawing in the spring of the following year, the ground was burrowed. Transplanting was carried out from Qingming Festival to Grain Rain. When transplanting, follow the ploughing and rake flat, and then open holes to plant seedlings. Generally, the depth of the hole is 16.5 cm, the distance between rows is 23 cm, and the distance between points is 20 cm, digging into a triangle. Three seedlings were planted in each hole, and the soil was covered with 1.65 cm and 3.3 cm. Seedlings after transplanting. You usually have to hoe three times or four times. If bolting plants are found, they will be pulled out immediately, combined with topdressing oily fertilizer.

Angelica is prone to root rot, it can be sprayed with 1000 times solution of 50% bacillus; after the occurrence of brown spot, cut off the diseased leaves immediately, and then spray 65% Diesen zinc solution to prevent and cure.
