What conditions are needed for growing Angelica sinensis? Detailed explanation of growing environment requirements
Angelica sinensis is a medicinal herb commonly used by people, and it is mainly cultivated in Shaanxi, Hubei, Sichuan, Yunnan and other places in China. So, what are the growing conditions for Angelica sinensis?
1. Soil requirements
Angelica sinensis is suitable for growing in areas with higher altitude; the general planting site is at an altitude of more than 2400 m. At too low an altitude, planted Angelica sinensis has low yield and poor quality, and it is also prone to bolting early. A sandy loam soil with deep, fertile, loose soil, good drainage and high humus content is preferable.
2. Fertilization requirements
When transplanting, increasing fertilizer application can promote yield at that time. Generally, fertile black soil is chosen for raising seedlings, applying a large amount of mountain ash farm manure as base fertilizer together with nitrogen, phosphorus and inorganic fertilizers. Applying more nitrogen fertilizer in the early stage of vegetative growth and more phosphorus and potassium fertilizer in the later stage can significantly improve the yield and quality of Angelica sinensis.
3. Environmental requirements
Temperature: Angelica sinensis is suitable for growing in areas with higher altitude, so it is suited to high-cold temperature conditions, and it is also relatively sensitive to temperature. The optimal suitable growth temperature is between 20-24 degrees; maintaining this temperature range during the seedling stage can make it emerge quickly.
Water: Angelica sinensis has very poor drought resistance and waterlogging resistance, which shows that its requirements for water conditions are relatively strict. A soil moisture content of about 25% is most suitable for the growth of Angelica sinensis. Timely irrigation and drainage are one of the main means of obtaining high yield at that time.
Light: Angelica sinensis belongs to the high-cold long-day development type, so under long-day conditions it grows well, develops quickly and bolts easily.
Angelica sinensis is a plant that likes light and fertilizer, so when planting, choosing a sunny slope and applying additional fertilizer in time are conducive to root growth.
