First, fertilizer characteristics:
Nitrogen, phosphorus, potassium nutrient content ≥ 40% (N18-P2O510-K2O12), is conducive to crop nutrient balance and fertility, fertilizer is soluble in water, nitrogen, rapid, significant effect, generally increase production by 20% to 30%.
Second, fertilization recommendations (kg/mu)
Crop Base Fertilizer (Composite Fertilizer) Top Dressing (Urea) Dressing Period Wheat 35-40 About 8 Points Rice Season 30-35 About 10 Spike Differentiation Stage Maize 25-30 About 12 Jointing Stage Potato 25-30 About 10 Flowering Beet 35- 40 about 10 days after seedling cotton 28-32 about 10 flowering bell oil rape 30-35 about 12 buds of the vegetable annual application of compound fertilizer 80-100 kg, of which about 40% as base fertilizer, the remaining 60% 2-3 times topdressing . After the autumn harvest, the mature tree of fruit trees can be applied to 1-2 kilograms of compound fertilizer per plant at the early stage of flowering and late growth. Third, pay attention to fertilizer applied in the bottom of the seed or plant 5-8 cm, the amount of high-acre yield should be biased upper limit, low yield should be lower limit; if the compound fertilizer applied to legumes, should increase phosphate fertilizer; fertilizer period can be Make appropriate adjustments according to the local conditions.
