Green onions: Before planting, the ground preparation and application of organic fertilizer 5000 kg, potassium sulfate compound fertilizer 30-40 kg. After the fall, chase 1 leaf attack fertilizer, 25-30 kg of potassium sulfate compound fertilizer, 20-30 kg of potassium sulfate compound fertilizer after administration, 10-15 kg of potassium sulfate compound fertilizer when white dew to autumn, 5 kg of urea .
Onion: Combined with ploughing and ploughing, the soil is applied with 2000-3000 kg of high-quality and decomposed farmyard manure and 40-50 kg of potassium sulphate compound fertilizer. After the spring, the plants enter a period of vigorous growth, which can be applied 1 to 2 times. Generally, 15-20 kg of potassium sulfate compound fertilizer is applied. When the small bulb is increased to about 3 cm, it is necessary to topdress in time, and apply 700-1000 kg of decomposed manure or 10-15 kg of potassium sulfate compound fertilizer per acre. When the phosphorus stem continues to grow to 4-5 cm, the fertilizer is chased once again, and 15-20 kg of potassium sulfate compound fertilizer per mu is applied.
Chili: Combine with the land preparation, apply 5,000 kg of high-quality farmyard manure with full-fertilization, 40-50 kg of potassium sulfate compound fertilizer. After the first top dressing, after the plant survived, 8-10 kg of urea was applied per mu. For the second time, when the plants are budded, 10-15 kg of potassium sulfate compound fertilizer is applied. The third top dressing is applied when the first ear fruit begins to expand, and 10-15 kg of potassium sulfate compound fertilizer per acre is applied or applied, followed by watering. The fourth time is applied in the peak period, combined with watering, 10-15 kg of potassium sulfate compound fertilizer.
Chinese cabbage (cabbage): When ploughing and ploughing, apply 2500-3000 kg of fully decomposed organic fertilizer and 25 kg of potassium sulphate compound fertilizer. Fertilization is carried out in the seedling stage, rosette stage, early stage of ball formation and mid-ball formation. 25-30 kg of potassium sulfate compound fertilizer is applied per mu, and heavy fertilization is carried out at the beginning of the ball, and the amount of fertilizer is three times that of other periods. It can be applied before the cabbage is closed and the ridge can be applied after the ridge is closed.

Cucumber: Generally, the cucumber fertilizer is used to produce 5,000 kg of high-quality organic fertilizer per acre and 50 kg of potassium sulfate compound fertilizer. The principle of topdressing is a small number of times. The total amount of topdressing is about 50 kg. The topdressing should be applied with water. Once a month, the urea and potassium sulfate compound fertilizer are used alternately, and the amount of each mu is 10-15 kg.
