Pollution-free cultivation technology of kale

1. Land preparation. Early ploughing and more turning, breaking the rake level, applying sufficient base fertilizer, the depth of the plough layer is 15-20 cm, and high tillage cultivation is good for drainage.

2. Fertilize. Combined with land preparation, basal fertilizer is applied, and the basal fertilizer is mainly rotten organic fertilizer. Attention should be paid to the balanced application of phosphorus and potassium fertilizers. About 60% of nitrogen fertilizer and phosphorus and potassium fertilizers were combined and applied on the cultivated land and the soil layer. The proportion and amount of phosphorus and potassium fertilizers are determined according to the local soil fertility.

3, sowing seedlings. Generally, seedlings are used for transplanting, and the planting density after transplanting. The row spacing of early-maturing varieties × 18-20 cm × 16-18 cm, the spacing of middle-maturing varieties × 20-25 cm × 20-25 cm, the spacing of late-maturing varieties × space It is 25-30 cm x 25-30 cm. Protected planting density can be appropriately reduced.

4. Water and fertilizer management. Spraying a new high-fat film after planting can effectively prevent the ground water from evaporating, the seedling body water from transpiration, and isolate diseases and insect pests. At the same time, the seedling water is irrigated for about 7 days, and Yangfeng compound fertilizer is applied. The plant is budding to the development stage of rape, and can be topdressed with nitrogen, phosphorus, and potassium compound fertilizers + photosynthetic nutrition film fertilizers + vegetable stem spirits to make the stems of the plants thick, the leaves are thick, the leaves are fresh, the plants are lush, and the natural taste is strong. Help plants absorb a large amount of light fertilizer, light energy, light, compatible with conventional fertilizers, and nourish the plants to their limit. And continuous watering 2 to 3 times. After harvesting, the main loquat should be topdressed with nitrogen, phosphorus, and potassium compound fertilizers 2 to 3 times, and watered frequently to keep the field moist.

5. Cultivation and weeding. After slow seedlings and before plant buds should be planted 2 to 3 times in succession, weeding in time with combined cultivation, and soil and fertilizer cultivation in combination with cultivation.

6, pest control. Select disease-free seeds and excellent disease-resistant varieties; cultivate disease- and pest-free strong seedlings, rational layout and implement crop rotation; pay attention to irrigation and drainage to prevent soil drought and water accumulation; clean the countryside, strengthen weeding, and reduce the number of disease and insect sources. It can also use yellow board trapping, silver gray film to avoid aphids and insect net barriers, insecticidal lamp trapping and other precautionary measures.
