Angelica is a perennial herb whose root can be used as a medicine and is one of the most commonly used traditional Chinese medicines. It is mainly distributed in Gansu, Yunnan, Sichuan, Qinghai, Shaanxi, Hunan, Hubei, Guizhou and other places. Angelica can also be used in the preparation of halogen products. Its main features are to increase the fragrance and increase the flavor of meat products and medicines.
Angelic planting altitude requirements
It was suitable for planting at higher altitudes. Therefore, nursery fields in Jixian County and Jixian County are generally selected at an altitude of 2,400 meters above sea level, and transplanting sites are often selected in areas with an average elevation of 2,200-2,300 meters. When the altitude is too low, the planting of Angelica is low, the quality is also poor, and it is easy to twitch in advance.
Soil environment planted by angelica
Angelica is a favorite fertilizer crop. Sandy loam with deep soil layer, fertile and loose, good drainage and high humus content is suitable. Adding fertilizer during transplanting can promote the increase of production at that time. Generally, fertile black land seedlings are selected, and a large amount of mountain ash agricultural fertilizer is used as the base fertilizer. In addition to applying the bottom, it is also necessary to apply nitrogen, phosphorus and inorganic fertilizers. Nitrogen is the main component of protein composition, which can promote the growth of vegetative bodies, increase leaf area, thereby improve photosynthesis ability and increase accumulation of organic matter; phosphate fertilizer can strengthen root development, promote root system and improve the ability to absorb nutrients and water; It can promote the transportation and storage of photosynthesis to the roots, accelerate the meat quality of the roots, and improve the quality of angelica. Therefore, the application of nitrogen fertilizer in the early stage of nutrient production, and the later application of phosphorus and potassium fertilizer can significantly improve the yield and quality of Angelica.
Angelica planting temperature conditions
Angelica is native to the Gaoshan area in Jixian and Suichang. The temperature requirements are strict and suitable for high and cold weather conditions. At the time, under the suitable water conditions, the emergence time of the seeds was shortened with the increase of temperature. When the average temperature was 12-14 °C, the seedlings appeared 15-20 days; when the average temperature was 20-24 °C, the seedlings appeared 7-15 days; the average temperature was Above 14 °C, the aboveground and underground parts grow rapidly. When the average temperature in August is above 16 °C, the growth rate becomes slower. When the temperature drops below 13 °C after September, the above part begins to age and the roots accelerate growth. It is the main period of growth of medicinal materials.
Water demand for angelica planting
The drought resistance and blast resistance of Angelica are very poor, which indicates that the requirements for water conditions are strict, and the soil water content is about 25%, which is most suitable for Angelica growth. Therefore, abundant rainfall is one of the conditions for obtaining high yield of angelica. When the soil water content exceeds 40%, locust disaster occurs, and the root rot is easy to eat. When the soil water content is less than 13%, drought damage will occur and water needs to be replenished. Therefore, timely irrigation and drainage is one of the main means of obtaining high yield at that time.
Angelica planting lighting conditions
Angelica belongs to the type of high-cold long-day sunshine development, so it grows well under long-day conditions, develops rapidly, and is easy to pump. This is the characteristic of Angelica growth. In order to reduce early convulsions, it is often selected on a shady slope or flat land, and covered with grass at the seedling stage. However, insufficient light can not be obtained in the medicine period. Therefore, the appropriate slope, slope and planting density adjustment light are used in production to facilitate root development.
