How to Plant Astragalus complanatus? Detailed Explanation of Planting Methods and Key Technical Points
Astragalus complanatus is a herbaceous plant of the legume family and an important medicinal material mainly used to treat male conditions. It is generally used to treat kidney deficiency, spermatorrhea, premature ejaculation, etc., and also has the effect of nourishing the liver and improving eyesight. The planting history and usage history of Astragalus complanatus are both relatively long, and it is currently mainly cultivated in Northeast China, North China, as well as Henan and Shaanxi and other regions of China. How should Astragalus complanatus be planted? Below we will learn about its planting methods together.
1. Land Selection and Cultivation
Astragalus complanatus has the characteristics of preferring coolness, preferring light, being drought-tolerant, salt-alkali tolerant, and having strong adaptability. It does not have high requirements for the soil of the planting site. Generally, wild Astragalus complanatus grows on hillsides, roadsides, riversides, grasslands, etc., which also shows that Astragalus complanatus can basically be planted in any soil. However, if high yield is desired, then relatively fertile sandy loam soil with convenient drainage and irrigation is the most suitable. Deeply plow the land, clear the weeds in the field, and then apply fertilizer at a rate of two thousand to three thousand kg per mu, mainly organic fertilizer, supplemented with an appropriate amount of phosphate fertilizer and potassium fertilizer. Make the beds, level the ground, and then sowing can be carried out.
2. Propagation Methods
Astragalus complanatus is mainly propagated by seeds. In most regions of China, two seasons of cultivation can generally be carried out, that is, from the end of March to the end of April each spring, and from the end of August to the end of September each autumn. Sowing usually adopts the drill sowing method, with a row spacing of about thirty to thirty-five cm between rows, a furrow depth of about three to five cm, then water each furrow thoroughly, and finally scatter the seeds evenly into the furrows, covering with a thin layer of soil to bury the seeds.
3. Field Management
After sowing, the field temperature should be controlled at around fifteen degrees, and seedlings generally emerge in about fifteen days. Before the seedlings emerge, we should water appropriately, which helps promote the seedling emergence speed of Astragalus complanatus, generally watering once every three days or so. After the seedlings emerge, we should reduce the frequency and amount of watering to prevent excessive growth of Astragalus complanatus. When the seedlings grow to ten cm tall, we should carry out thinning, evening out, and replanting of seedlings. Generally, planting is set at a spacing of fifteen cm per plant, leaving two to three robust seedlings per hole. During the rainy season, drainage should be carried out in a timely manner, and fertilizer should be applied scientifically at different growth stages of Astragalus complanatus. During the growth period and flowering period, manure and urine water is generally the main fertilizer, while during the greening period, barnyard manure is mainly used, and fertilization is needed at least four times a year.
4. Pest and Disease Control
Astragalus complanatus has strong resistance, and few pests or diseases occur. At present, the most common pests and diseases of Astragalus complanatus are powdery mildew and wireworm. Powdery mildew mainly harms the stems and leaves of Astragalus complanatus, while wireworm mainly harms the roots of Astragalus complanatus. We can carry out prevention through garden cleaning and disinfection. At the same time, in the early stage of disease onset, thiophanate-methyl can be used to control powdery mildew, and lead phosphate can be spread to deal with wireworm.
