Analysis on cultivation and Management of Radix Astragali

Fertilizer and water management problems.

Fertilization is dominated by organic fertilizer and supplemented by chemical fertilizer to maintain or improve soil fertility and the activity of soil microorganisms. Spraying the medicinal herb Gandaling in time at the seedling stage can activate the positive energy of plant ecological growth, broaden the path of plant ducts, enhance the intensity of water and fertilizer absorption, and improve the yield and quality. After sowing, sprinkler irrigation is used to make the bed moist and ensure the evenness of seedlings. After emergence, sprinkler irrigation should be carried out according to the rainfall in the field during drought; when there is stagnant water in the field in the rainy season, attention should be paid to drainage to prevent the root rot of Astragalus membranaceus.

The problem of seedling and seedling supplement between weeding and weeding in mid-tillage.

After emergence, ploughing and weeding in time, and pay attention to cultivate soil to the ridge, so that the ridge to maintain the original width. Weeding is generally needed for 2 or 3 times. When the height of the seedling is 5cm and 7cm, the time seedling and fixed seedling should be fixed, and the plant spacing is 3cm. When there is a lack of seedlings and broken strips, it should be combined with fixed seedling transplanting. Spraying 600 times liquid of new high lipid film in time after replanting can improve the survival rate and restore the exuberance of plants.

The problem of disease and insect control.

Comprehensive measures such as agriculture, physics, biology and chemistry are adopted to prevent and control diseases and insect pests. Spraying pesticides should be used together with new high lipid membrane to improve the utilization rate of effective components of pesticides, which can transform high toxic pesticides into poisoning, poisoned pesticides to low toxicity, and low toxic pesticides to slight toxicity. Control the volatilization of pesticides, prevent the erosion of little Rain Water, reduce the dosage per mu (halved), and improve the control effect (many times). (Earth)
