Angelica sinensis, a mystical Chinese medicinal material, is deeply rooted in the soil of Gansu, Yunnan and Sichuan in China, and has won the reputation of "Nine Returns in Ten Directions" for its excellent blood tonic and blood activation, menstrual regulation and pain relief, and is widely used in the clinical practice of Chinese medicine. As an authentic Chinese medicinal material, its planting conditions and methods have strict requirements and scientific procedures.
First, let's dive into Angelica's unique needs for soil conditions. This precious herb prefers deep, well-drained soils, and is ideally based on loose, fertile sandy loam soils or organic-rich black soils, which contribute to the full development of its roots and nutrient absorption. In addition, the soil pH is maintained at 65-7.The slight acidity to neutral state between 5 can better meet the optimal physiological needs of the growth of Angelica sinensis, and is conducive to the accumulation of its active ingredients.
Secondly, climatic conditions are crucial for the growth of Angelica. It is cold-tolerant but not heat-resistant, and prefers a cold, moist and sunny ecological environment. Spring sowing is the most suitable choice, as the temperature range at this time is about 15-23, which is conducive to seed germination without affecting the normal growth of the seeds due to high temperatures. Angelica sinensis cannot tolerate long periods of direct sunlight, so choosing a plot of semi-shade or proper shade can effectively avoid the growth stunted by too strong sunlight.
In terms of planting methods, it is necessary to be careful and meticulous from the beginning of seed selection. Select excellent seeds that are full and free of diseases and pests, and carry out germination treatment, such as warm water soaking, before sowing, which can improve the vigor and emergence rate of seeds. March-April after the soil thaws in spring is the best time for angelica to be sown. Strip sowing or hole sowing can be, but pay attention to control the sowing depth of about 2-3 cm, the row spacing is about 25-30 cm, the plant spacing is 15-20 cm, and the sowing amount per mu is usually controlled at about 3-4 kg, so as to ensure that there is enough space between plants for growth and development.
Field management should also not be neglected, after sowing to ensure that the soil is moist to facilitate seed germination, and after the emergence of seedlings, it is necessary to weed in time to avoid weeds competing for nutrients. Timely and appropriate topdressing of fertilizer during the growth period can not only promote the lush stems and leaves of Angelica sinensis, but also increase the accumulation of nutrients in the roots. At the same time, in view of possible pests and diseases, the principle of prevention first and comprehensive control should be adopted to ensure the healthy growth of Angelica sinensis.
At the end of autumn, when the aboveground parts of Angelica sinensis are yellow, it is the best time to harvest. It is necessary to minimize the damage to the roots when digging, because the active ingredients of Angelica sinensis are mainly concentrated in the roots. After digging, Angelica sinensis is washed with soil, first dried until semi-dry and then accumulated to sweat, and then continues to dry until it is completely dry, so that the processed commodity Angelica can give full play to its medicinal effect.
In general, although the above provides the basic conditions and methods for the cultivation of Angelica sinensis, in the actual operation process, it is also necessary to flexibly adjust and optimize according to the specific climatic characteristics, soil conditions and planting experience of farmers. Only in this way can we better cultivate angelica with good quality and remarkable medicinal effects, so that this ancient Chinese herbal medicine will glow with more brilliant vitality in the context of the new era.
