Field Management method of Angelica sinensis

The main results are as follows: (1) check the seedlings and replenish the seedlings of Angelica sinensis after general transplanting, and check and replenish the seedlings in time after the seedlings are completed.

(2) Intermediate ploughing and weeding should be carried out three times after seedling emergence, the first time weeding when the seedling height is 5 cm, shallow ploughing and shallow hoe; the second time weeding when the seedling height is 10 cm and 15 cm, appropriate deep hoe; the third time, when the seedling height is 25 cm and 30 cm, the weeding is combined with intertillage weeding and soil cultivation.

(3) topdressing of Angelica sinensis at seedling stage should not be more than nitrogen fertilizer, so as not to flourish. In the middle and later stage, combined with middle ploughing and weeding and weeding, topdressing compound fertilizer 30,50kg per mu, topdressing is needed twice during the whole growth period.

When seedling height was 10~15cm, the total effective components were topdressing once, the total effective components 6 kg/666.7m2,N:P:K was 1 25~30cm, and the total effective components were 8kg, 666.7m ~ 2, and the total effective components were 666. 7m ~ 2 and 1:1:2 respectively. Inorganic fertilizer shall not be applied within 30 days before harvest.

(4) when there are early bolting plants in flower picking and moss cultivation due to improper control, they should be cut and cleaned as soon as possible, otherwise the quality of medicinal materials will be affected.

(5) Irrigation and drainage Angelica sinensis should be watered less in the early growth stage, properly watered when the soil is dry, it is better to keep the soil moist, avoid irrigation with heavy water, the field can not accumulate water in the later stage, and the stagnant water should be eliminated in time in the rainy season to prevent rotting roots.
