1. Fertilizer law. The production of 5,000 kg of fruit requires absorption of 17 kg of nitrogen, 5 kg of phosphorus and 26 kg of potassium from the soil. 2. Base fertilizer. About 8000 kg of rotten farmyard fertilizer is applied per mu, 40-50 kg of compound fertilizer or 50-75 kg of superphosphate, and 30 kg of ammonium sulfate. 2/3 arable land is applied, and 1/3 is applied to the planting line. Phosphate fertilizer is best used after stacking with livestock manure and various organic fertilizers. 3. Top dressing. After 10 to 15 days after planting, the planting period was 500 kg of manure per mu, or 10 kg of ammonium sulfate. After cultivating, cultivating soil immediately and appropriately seedlings. When the first fruit begins to swell, it will be top-dressed for the second time. Apply 20 kg of ammonium sulfate per mu, 8 kg of superphosphate, 800 kg of human waste, 50-80 kg of plant ash (dry weight), but the ash should not be mixed with nitrogen. Fertilizer mix. The first fruit was harvested, and the second fruit was magnified for the third time. The application of ammonium sulfate was 15-20 kg per mu, or 1000 kg of human waste. After harvesting each fruit once, with the water applied nitrogen fertilizer available near 10 kg per mu. 4. Foliar fertilization. When the plants showed symptoms of fertilizer deficiency, 0.2% potassium dihydrogen phosphate could be sprayed. The emergence of tomato umbilical rot, spraying 0.5% calcium chloride solution. Fertility at the late seedling stage at the seedling stage is insufficient, and foliar spray of 0.1% to 0.2% urea is available. Phosphorus spraying, the general use of superphosphate leaching solution, the method is 1.5 kilograms of superphosphate, add 5 kilograms of water (requiring about 50 °C hot water), continue to stir, put it a day and night, take the supernatant, add water, 50 kg, that is A 3% superphosphate leachate. When spraying, it is required to spray the foliage and the back of the leaves, preferably in the evening. 5. Protective carbon dioxide application. When the carbon dioxide reaches 0.08% to 0.15%, the yield is the highest. In production, sulfuric acid and ammonium bicarbonate are commonly used to release carbon dioxide.
