First, the fertilization for soil preparation: Select a sandy soil layer with thick soil, convenient drainage and irrigation, rich in organic matter, loose air, and planting. Apply enough base fertilizer and spray a new high-fat film to protect the soil. Second, the appropriate sowing: selection of good disease-resistant varieties, with a new high-fat membrane seed dressing, the whole subterranean species, the new high-fat membrane 600-800 times spray the surface of the soil, moisture can be preserved moisture evaporation, sunscreen drought, thermal insulation, antifreeze, The soil-proof layer is compacted, suffocates and isolates the source of diseases and insects to increase the emergence rate. 3. Water and Fertilizer Management: Soil moisture should be maintained before emergence. The seedling stage should be used to induce seedlings to evacuate the membrane and wet the water once. The seedling stage should be kept dry and wet as soon as possible. The root swelling stage should be kept dry and rare. According to the plant grows a reasonable top dressing. IV. Pest Control: Pests and diseases that damage carrots include root-knot nematodes, aphids, black rot, and black spot diseases. Control methods, spraying targeted drugs and adding new high-fat membranes, can regulate water absorption, and are not afraid of sun exposure and evaporation. Greatly increase the utilization of effective ingredients of pesticides and fertilizers. Fifth, growth: from the root to the harvest of fleshy roots are harvested. During this period, the roots of the fleshy root grow in a secondary way, and the cell gap also increases continuously, forming a lateral growth. Therefore, the fleshy roots are gradually thickened by the slender shape of the seedling stage, and the sprayed fruit shuangtingling thickens the underground fruit nutrient transport conduits. Fruit and fruit enlargement and vitality, smooth fruit surface, robust fruit type, high quality and high yield.
