First, the melons, including: cucumber, wax gourd and other fertilization principles: focusing on organic fertilizer, focusing on the base fertilizer, reasonable fertilizer, control of nitrogen fertilizer application, prohibit the application of nitrate nitrogen fertilizer, soil testing formula, to maintain balanced soil fertility.
Apply base fertilizer: Ensure that the organic fertilizer is applied to 4000-5000 kg/mu, diammonium phosphate 30-50 kg/mu, potassium sulfate 40-60 kg/mu or three-element compound fertilizer 100 kg/mu.
Appropriate top-dressing: Each mu can be followed by decomposed human excrement 1000 kg/mu or ternary compound fertilizer (or urea) 10 kg/mu. At the same time 0.5% urea can be added with 0.3-0.5 potassium dihydrogen phosphate supplemented with foliar fertilizer 2-3 times. CO2 gas can be added to the protected area. It is forbidden to use harmful municipal waste and sludge, and the manure fertilizer cannot be used for fertilizing in the harvesting stage.
Second, eggplant vegetables, including: tomato, pepper, eggplant and other fertilization principles: the main organic fertilizer, focusing on the base fertilizer, a reasonable top dressing, control the amount of nitrogen fertilizer, promote the use of special fertilizers and biological fertilizers, soil testing formula, maintain soil fertility balance.
Applying basic fertilizer: Ensure that the fully applied organic fertilizer is applied in an amount of 4000-5000 kg/mu, with the application of diammonium phosphate 30-50 kg/mu, potassium sulfate 40-60 kg/mu or ternary compound fertilizer 100 kg/mu.
Appropriate top-dressing: Each mu can be followed by decomposed human excrement 1000 kg/mu or urea 10 kg/mu. It is forbidden to use harmful municipal waste and sludge, and the manure fertilizer cannot be used for fertilizing in the harvesting stage.
Third, leafy vegetables, including: Chinese cabbage, cabbage and other fertilization principles: the main organic fertilizer, focusing on the base fertilizer, reasonable fertilizer, control the amount of nitrogen fertilizer, promote the use of special fertilizers and biological fertilizers, prohibit the use of nitrate nitrogen fertilizer, soil testing formula To keep the balance of soil fertility.
Apply base fertilizer: Ensure that the organic fertilizer is applied to 4000-5000 kg/mu, diammonium phosphate 30-40 kg/mu, potassium sulfate 30-40 kg/mu or ternary compound fertilizer 80 kg/mu.
Appropriate top-dressing: The application of slow-acting fertilizers in the early and middle stages can be followed by adequately decomposed human excrement 1000 kg/mu, plant ash 50-100 kg/mu or ternary compound fertilizer (or urea) 10 kg/mu. Appropriate post-appropriate application of ammonium bicarbonate 20-30 kg/mu or urea 10 kg/mu. It is forbidden to use harmful municipal wastes and sludge, and it is not possible to use manure-fertilizer in the harvesting stage.
