First, the foot base fertilizer
The amount of base fertilizer should account for 80%-90% of the total amount of fertilizer. Some peanut fields only need to apply the base fertilizer, and high yield can be obtained without top dressing in the later stage. The base fertilizer can be used for 1000-3000 kg of high-quality farmyard manure per acre.
Second, increase the application of phosphate fertilizer
Peanut requires more phosphate fertilizer than general crops, and the absorption and utilization rate of phosphate fertilizer is also high. The test proved that 10 kg of calcium phosphate per acre was applied, and the yield increase effect was remarkable, and the aftereffect was obvious. When the phosphate fertilizer is applied in a thin manner, 2.5-5 kg ​​of urea is added per mu as a seed fertilizer, and the effect of increasing the yield of the phosphate fertilizer can be exerted. However, when applying the seed fertilizer, the fertilizer and the seed should be isolated to avoid harming the seed and affecting its germination and emergence.
Third, clever application of calcium fertilizer
Peanut application of 10 kg of calcium sulfate per acre can not only adjust the pH value of the soil, improve the nitrogen fixation capacity of the rhizobium, but also improve nitrogen nutrition, promote pod development, and reduce empty fruit and rotten fruit.
Fourth, suitable for bacterial fertilizer
Artificial inoculation of peanut rhizobium can make early nodule and multi-root nodule of peanut, and improve the nitrogen fixation ability of peanut plants. At present, the peanut rhizobium agent (rhizobial fertilizer) is generally used for 25 grams per acre. When using it, add appropriate amount of water to make a paste and mix well with seeds. Pay attention to mixing with seeds to prevent sun exposure. Also avoid mixing or contact with fungicides.
