Analysis of Common Problems in Astragalus Cultivation and Management

Fertilizer and water management problems.

Fertilization should be based mainly on organic fertilizer, supplemented by chemical fertilizer, to maintain or improve soil fertility and the activity of soil microorganisms. During the seedling stage, promptly spray Gen Da Ling for medicinal herbs, which can activate the positive energy of plant ecological growth, broaden the plant's conduit pathways, enhance the plant's water and fertilizer absorption capacity, and improve yield and quality. After sowing, water by sprinkler irrigation to achieve a moist bed surface and ensure full seedling emergence. After emergence, carry out sprinkler irrigation according to rainfall conditions when the field is dry; during the rainy season, when water accumulates in the field, attention should be paid to drainage to prevent Astragalus root rot.

Problems of intertillage, weeding, thinning, and replanting.

After emergence, carry out intertillage and weeding in a timely manner, and pay attention to hilling soil toward the ridge platform so that the ridge platform maintains its original width. Generally, weeding is needed 2 to 3 times. When the seedlings are 5 to 7 cm tall, thinning and final thinning should be carried out in a timely manner, with a plant spacing of 3 to 5 cm. When there are missing seedlings or broken rows, transplanting and replanting should be carried out in combination with final thinning. After replanting, promptly spray a 600-fold dilution of Xin Gao Zhi Mo, which can increase the survival rate and restore the plants to vigor.

Pest and disease prevention and control problems.

Comprehensive measures such as agricultural, physical, biological, and chemical methods are used to prevent and control pests and diseases. When spraying pesticides, they should be used together with Xin Gao Zhi Mo to improve the utilization rate of the active ingredients of pesticides, and can transform highly toxic pesticides into moderately toxic ones, moderately toxic pesticides into low-toxicity ones, and low-toxicity pesticides into slightly toxic ones. Control pesticide volatilization and drift, prevent washing away by light rain, reduce the pesticide dosage per mu (by half), and improve the control effect (multiple times). (Dadi)
