How to fertilize Angelica sinensis properly? Master the scientific fertilization method

Angelica sinensis is also called danggui. At present, the best quality and highest yield on the market comes from the Minxian area of China. It is also grown in Yunnan, Sichuan and other places. Its medicinal part is its root, which is widely used in traditional Chinese medicine, often for nourishing blood, regulating menstruation, as well as anti-cancer and anti-aging purposes. Now the scale of Angelica sinensis cultivation has been further expanded, so do you know how to fertilize during the cultivation of Angelica sinensis? If not, you need to read the content below carefully.

1. Base fertilizer

Base fertilizer is the most basic nutrient supply for the growth of Angelica sinensis, and when applying base fertilizer we must apply enough, which can reduce a lot of later work. In ordinary cultivation, under relatively fertile soil conditions, each mu mainly uses decomposed barnyard manure or compost, combined with oil cake or phosphate fertilizer and phosphorus-potassium-nitrogen compound fertilizer. The amounts are 2,500 kg, 200 jin and 50 jin respectively. Finally, if conditions permit, it is best to also use about 130 jin of compound microbial fertilizer, which can increase yield and improve soil structure.

2. Seedling fertilizer

Angelica sinensis is a deep-rooted plant with a relatively large demand for nutrients, so when the base fertilizer is insufficient, we need to topdress in time. At the seedling stage, we mainly aim to promote the growth of the seedlings, so at this time we mainly use potassium dihydrogen phosphate, diammonium phosphate and compound fertilizer for topdressing, and each mu also needs about 20 jin of Hejin Dongli soluble fertilizer, which can promote seedling growth.

3. Growth fertilizer

In the early growth stage of Angelica sinensis, in order to avoid early bolting and flowering caused by excessive growth, nitrogen fertilizer still needs to be supplemented. We usually dilute manure and urine with water and then irrigate, with the amount per mu controlled at about 3,000 jin. It also needs to be topdressed together with phosphate and potassium fertilizer and ternary compound fertilizer, with the amount per mu kept at about 30 jin. Of course, we can also use barnyard manure or cake fertilizer for topdressing, with the amount controlled within 2,000 jin.

4. Yield-increasing fertilizer

In order to promote the growth of the rhizome of Angelica sinensis, we also need to topdress once in the middle and late stages of its growth. This topdressing has a very large impact on the yield and quality of Angelica sinensis. Generally, at this time we apply a relatively high-concentration manure and urine water once, and if conditions permit, we can also topdress cake fertilizer, phosphate fertilizer and barnyard manure, with the ratio of these three controlled at 1:0.5:0.2, which is beneficial to the growth of the root of Angelica sinensis.

We all know that for Angelica sinensis to have high yield, the most important thing is to promote the thickening of its root, so that high yield and high quality can be achieved. And to achieve high yield and high quality, nutrient supply is the key, so we should fertilize according to scientific fertilization techniques, so as to ensure the yield of Angelica sinensis.
