NOVELTY - Cultivation of Astragalus involves selecting well-drained sandy soil, plowing, fertilizing with organic fertilizer, calcium superphosphate, ammonium bicarbonate, rooting powder, potassium sulfate, and soil conditioner, leveling, and spreading on substrate; sowing, ditching, selecting seed, covering seed with nutrient soil, maintaining wet soil, and sprouting; rooting and adding strain; weeding; top dressing with high phosphate fertilizer and irrigating; removing bud; controlling pest and insects; and harvesting, cutting stems, digging root, shake off soil, drying, and binding in can.    USE - Method for cultivating Astragalus (claimed).    ADVANTAGE - The method has high yield and quality and less pests and insects.    DETAILED DESCRIPTION - Cultivation of Astragalus comprises:    (A) selecting well-drained sandy soil, plowing 35-40 cm deep, fertilizing with 2000-2500 kg organic fertilizer, 20-30 kg calcium superphosphate, 10-15 kg ammonium bicarbonate, 0.1-0.2 kg rooting powder, 8-10 kg potassium sulfate, and 20-25 kg soil conditioner, raking, leveling, spreading on substrate, where substrate comprises 20-30 pts. wt. rotten cotton straw powder, 15-20 pts. wt. ripe watermelon vine powder, 10-15 pts. wt. bagasse, 5-6 pts. wt. konjac powder, 0.1-0.2 pt. wt. yeast extract, 8-10 pts. wt. zeolite powder, 4-5 pts. wt. coal, 8-10 pts. wt. plant ash, 15-18 pts. wt. slag phosphate fertilizer, 3-4 pts. wt. potassium chloride, 30-40 pts. wt. garden soil, and 8-10 pts. wt. potassium humate;    (B) sowing in spring and autumn, ditching at row distance of 25-30 cm, selecting full and glossy seed, covering seed with nutrient soil, maintaining wet soil, and sprouting for 15 days, where seed quantity is 2-3 kg/mu;    (C) rooting at 5-7 cm and adding 1 strain every 5-10 cm stubble seedling;    (D) weeding for 2-3 times;    (E) top dressing with 30 kg high phosphate fertilizer and irrigating by watering;    (F) removing bud;    (G) controlling pest and insects; and    (H) harvesting after withering of stems and leaves, cutting stems, digging root, shake off soil, drying, and binding in small can.
