First, vegetable vegetables
For the outstanding problems of low organic fertilizer application, partial application, and excessive application of chemical fertilizers on fertilized vegetables, the basic fertilizer is dominated by organic fertilizers, and topdressing fertilizers are mainly available nitrogen fertilizers. Combined with phosphorus and potash fertilizers, attention is paid to Application of calcium and magnesium fertilizers.
1. About 3,000 kilograms of organic fertilizer that has been decomposed and detoxified after application of organic fertilizer.
2. Application of NPK fertilizer per acre below 1500 kg, 12 kg of N fertilizer per mu, 6 kg of P fertilizer and 9 kg of K fertilizer; 1500-2000 kg per acre, 11 kg of N fertilizer per mu, and 5.5 kg of phosphate fertilizer Potash fertilizer 8.5 kilograms; per acre yield levels above 2000 kilograms, Mushi nitrogen fertilizer 10 kilograms, phosphate fertilizer 5 kilograms, potash 8 kilograms.
3. Fertilize the proportion of basal fertilizer, generally 100% of organic fertilizer, 100% of phosphate fertilizer and 20% of nitrogen and potassium fertilizer are used as base fertilizer before sowing or transplanting. Miao Fei, the amount of nitrogen, potassium fertilizer is generally 10% of the total. In the vigorous growth period, the amount of fertilizer applied is generally 80% of the total amount of nitrogen and potassium fertilizers, and the top-dressing fertilizers are top-dressed, and fertilizers are topdressed once every 10 days or so. In addition, most leafy vegetables are hi-calcium, hi-magnesium crops. For areas where soil-exchangeable calcium and magnesium are below the critical value, calcium magnesium phosphate fertilizer should be used to supplement 10-20 kg of lime per mu or at the seedling stage. During the vigorous growth period, 0.3% calcium chloride solution or 0.25-0.5% calcium nitrate solution is sprayed to prevent leafy vegetables from seriously affecting product and quality due to physiological calcium deficiency or magnesium deficiency.
Second, melon, eggplant, fruit, beans vegetables
To solve the outstanding problems such as low organic fertilizer application, partial application or excessive nitrogen fertilizer application, and neglect of potash fertilizer application on melon, eggplant, fruit and legumes, we adhere to the combination of organic fertilizers and nitrogen, phosphorus and potassium. Application of potassium fertilizer in the middle and later stages has an important role in reducing malformed fruit and improving fruit quality.
1. About 3,000 kg of organic fertilizer applied per mu.
2. The application of nitrogen, phosphorus and potassium per acre yield below 2000kg, 13kg nitrogen fertilizer, 7kg phosphate fertilizer, and 10kg potassium fertilizer; the yield level per acre is 2000-2500kg, and the nitrogen fertilizer application is 12kg, and the phosphorus fertilizer is 6.5kg. Potash fertilizer 9.5 kg; per acre yield level of more than 2500 kg, 11 kg of nitrogen fertilizer, 6 kg of phosphate fertilizer, 9 kg of potassium fertilizer.
3, fertilization method basal fertilizer, generally before transplanting high-quality soil miscellaneous fertilizer or pig, cow manure 3000 kg, while 100% of the phosphate fertilizer and 20% of nitrogen and potassium fertilizer as a base fertilizer deep application. Miao Fei, the amount of nitrogen, potassium fertilizer is generally 10% of the total. During the ear development period, the amount of fertilizer applied is generally 70% of the total amount of nitrogen and potassium fertilizers applied. During this period, topdressing should be performed in stages, and top dressing should be applied once every 10 days. In the middle and late period, spraying with 0.2% potassium dihydrogen phosphate solution for 2-3 times has a good effect.
Third, root and stem vegetables
For roots and stem vegetables in the fertilization on organic fertilizer application is low, partial application and excessive application of nitrogen fertilizer, as well as neglect of potassium fertilizer application and other outstanding issues, adhere to the main organic fertilizer, chemical fertilizer fertilizer application of phosphorus, potassium, Nitrogen, phosphorus and potassium are used in combination with the three elements, with particular attention to the application of potash fertilizer in the middle and later stages. According to the principle of “one control, two promotions, three guarantees, and four taboosâ€, fertilization is divided into several stages. One control is to control fertilization during flowering to avoid falling flowers, fallen leaves, and falling fruit. The second is to apply fertilizer in time during young fruit and harvesting period. Promote the rapid expansion of young fruit; three guarantees is to ensure that the de-fertilizer, not leggy, free from fertilizer damage; four bogey is to avoid high concentrations of fertilizer, avoid wet soil top dressing, avoid high-temperature chase after the moon and avoid too concentrated dressing.
1. About 3,000 kg of organic fertilizer applied per mu.
2. The application of nitrogen, phosphorus and potassium per acre is below 2,000 kg. For a mu, 10 kg of nitrogen fertilizer, 7 kg of phosphate fertilizer and 10 kg of potash fertilizer; the yield level per acre is 2000-2500 kg, 9 kg of nitrogen fertilizer is applied per mu, and 6.5 kg of phosphate fertilizer is applied. Tablets, potassium 9 kg; per acre yield levels above 2500 kg, Mushi N 8 kg, phosphate 6 kg, potassium 8 kg.
3, fertilization method basal fertilizer, generally before transplanting high-quality soil miscellaneous fertilizer per mus or pig, cow dung 3000 kg, while 100% of the phosphate fertilizer and 30% of nitrogen and potassium fertilizer as a deep application of basal. The application rate of seedling fertilizer is generally 50% of the total amount of nitrogen and potassium fertilizers. During this period, fertilizers should be top-dressed in stages and top-dressed once every 10 days to promote the growth of stems and leaves and to increase the assimilation area. Hair-fertilizer, the application rate is generally 30% of the total amount of nitrogen and potassium fertilizer application, promote tuber enlargement and increase yield. Melon, eggplant, fruit, beans in the middle and late growth, spraying 0.2% potassium dihydrogen phosphate solution 2-3 times, has a good effect.
