The cultivation mode of Angelica sinensis

Angelica sinensis is a famous large amount of traditional Chinese medicine, which is called "gynecological holy medicine". It is not only the formula of "ten prescriptions and nine angelica", but also an important raw material of proprietary Chinese medicine. There are seven steps in the cultivation of Angelica sinensis, which are introduced as follows:

1. The shady Banyin Mountain should be selected for land preparation and seedling cultivation, and the loose and fertile sandy loam soil should be selected for cultivation land. In mid-July, first cut down shrubs and weeds, spread them on the ground, burn and refine the mountains, and then turn the land more than 25 centimeters deep and wind-cured in the sun. Then, before planting, combined with land preparation, 2500 kg of rotten barnyard manure per mu was applied and turned into the soil as base fertilizer. Shallow ploughing once before sowing to make a high border 1.3 meters wide, the border ditch is 40 centimeters wide, and a good drainage ditch is opened around.

2. The suitable time for transplanting is generally in the first and middle of April. Early, the seedlings are easy to be harmed by late frost; too late, the seedlings have germinated, reducing the survival rate. In the whole rake fine planting ground, layer seedlings, according to the row spacing of 33 × 27 cm according to the triangle staggered hole, the hole depth of 20 cm. Then, the root neck of the seedling was 0.3 cm thick and 0.4 cm thick, and 3 seedlings were planted in each hole according to the zigzag arrangement. After the planting, the seedlings were pressed while covering the soil. When the soil was covered to half a hole, the seedlings were gently lifted up to make the root system stretch, then cover the soil to the full hole, apply an appropriate amount of fire soil ash or soil miscellaneous fertilizer, and cover the fine soil not over the root neck of the seedling.

3. When the height of inter-seedling and fixed seedling is 3 cm, the first seedling is carried out, and the second seedling is carried out half a month later, and when the seedling height is 10 cm, the seedling is fixed. There were 2 or 3 strong seedlings in each hole.

4. Weeding by intertillage is carried out 3 or 4 times a year. The first time after the seedling, when the seedling height is 3 cm, the combined seedling weeds once, the second time when the seedling height is 6 cm, the combined seedling weeds again, at this time, because the main root has not yet been rooted into the deep layer, it is suitable for shallow middle ploughing; the third time after the seedling is fixed, it can be deepened properly; the fourth time when the seedling height is 20cm and 25cm, you can hoe deeply, and no longer ploughing and weeding after closing.

5. Topdressing should not be applied too much nitrogen fertilizer at seedling stage, so as to avoid early bolting caused by excessive growth. In the middle and later stage of growth, human and animal dung water, fire soil ash or compost can be increased by 2000 kg per mu. When there are conditions, cake fertilizer, calcium superphosphate and stable fertilizer can be piled and ditched between rows, and then covered with soil to cover fertilizer and cultivate soil to facilitate root growth.

6. Drainage and irrigation in the early growth stage, except for proper watering during drought, generally control the use of water, Rain Water is too much, it is necessary to timely dredge ditches and drainage, especially in the later growth stage, the field can not accumulate water, otherwise it is easy to cause rotting roots.

7. Breeding Angelica sinensis is a herbaceous plant, but it is not annual, and its growth cycle is three years. The first year: seed-seedling; the second year: seedling-adult; the third year: adult-seed, such a process.
