Combine ploughing, leveling the uneven land with a spade, shovel and rake, and remove weeds, straws and stones.

III. Application of base fertilizer

Mainly with organic fertilizer, supplemented by chemical fertilizer, more than 3000 kg of rotten farm manure and 30 kg of diammonium phosphate were applied per mu. Farm manure and diammonium phosphate were evenly scattered on the surface before sowing and mixed into the ploughed soil.

4. Selection of seedlings

The high quality seedlings with no disease infection, no mechanical damage, few lateral roots, smooth epidermis and 2-5 mm in diameter (100 seedlings weighing 80-110 grams) were selected.

5. Planting

The row spacing is 33 cm, and there are more than 6000 seedlings per mu. Two seedlings are planted in each litter, the distance between the two seedlings is 3Mel and 4cm, and the seedlings are placed in the nest separately, filled, compacted and covered with soil about 2cm.

VI. Field management

1. Check nest and replenish seedlings: after Angelica sinensis planting, check whether there are damaged seedlings, missing nests, withered and dead seedlings. If the missing rate reaches 10%, the seedlings should be replenished in time, and the seedlings prepared on the edge of the ground will be transplanted with soil on overcast and rainy days. When it is found that the roots are rotten, dig out the dead seedlings with the head, collect all the roots, stems and leaves together, burn them away from the planting field, and bury the ashes deep in the soil, sprinkling 100 grams of plant ash into each hole.

3. Fixed seedlings and bolting plants: combined with the second and third times of ploughing and weeding, pulling out or cutting bolting plants with scissors; fixing seedlings in the third time of weeding, 1 plant in each hole.

4. Topdressing: combined with intermediate ploughing and weeding, a small amount of urea can be applied at the seedling stage and foliar spraying with 0.5 kg of potassium dihydrogen phosphate and 30 kg of water per mu before root growth.

VII. Harvest

From late October to early November of the year in which Angelica was planted, the aboveground part was cut off when the leaves of Angelica turned yellow and withered. 5Mel will be excavated after 7 days. When harvesting and digging, you must be careful not to hurt the root, shake the soil out of the angelica root, pick out rotten water and vegetable heads, and place them in a ventilated and sunscreen place.
