Embodiment 1
[0014] Accurately weigh 9 kg of urea, 55 kg of superphosphate, 8 kg of potassium sulfate, 144 kg of potassium sulfate slow-release compound fertilizer with N:P:K ratio of 20:6:19, 13 kg of calcium sulfate, and 1 kg of molybdenum ammonium acid and 0.8 kg of borax, mix well. When planting 1 mu of Huayu 33 peanut varieties in spring, one-time use as a base fertilizer is suitable for peanut fields, providing sufficient nutrients for the growth and development of peanuts. When the needles and pods of the peanuts are set, spray a mixed solution consisting of 0.7% potassium dihydrogen phosphate solution, 0.2% zinc sulfate solution and 0.2% ferrous sulfate solution, and spray 100 kg of mixed solution per mu. Spray once every 8 days and spray 3 times in a row. After the peanuts were harvested in autumn, the yield per mu reached 582 kg, and the yield per mu increased by 12%.
Embodiment 2
[0016] Accurately weigh 8 kg of urea, 50 kg of superphosphate, 7 kg of potassium sulfate, 130 kg of potassium sulfate slow-release compound fertilizer with N:P:K fertilizer ratio of 20:6:19, 12 kg of calcium sulfate, and 0.8 kg of molybdenum ammonium acid and 0.6 kg of borax, mix well. When planting 1 mu of Huayu 33 peanut varieties in spring, one-time use as a base fertilizer is suitable for peanut fields, providing sufficient nutrients for the growth and development of peanuts. When the needles and pods of the peanuts are set, spray a mixed solution composed of 0.8% potassium dihydrogen phosphate solution, 0.3% zinc sulfate solution and 0.3% ferrous sulfate solution, and spray 100 kg of mixed solution per mu. Spray once every 8 days and spray 3 times in a row. After the peanut harvest in autumn, the yield per mu reached 602 kg, and the yield per mu increased by 14%.
Embodiment 3
[0018] Accurately weigh 8.5 kg of urea, 52 kg of superphosphate, 7.5 kg of potassium sulfate, 140 kg of potassium sulfate slow-release compound fertilizer with N:P:K fertilizer efficiency ratio of 20:6:19, 12.5 kg of calcium sulfate, and 0.9 kg of molybdenum ammonium acid and 0.7 kg of borax, mix well. When planting 1 mu of Huayu 33 peanut varieties in spring, one-time use as a base fertilizer is suitable for peanut fields, providing sufficient nutrients for the growth and development of peanuts. When the peanuts are needled and podted, spray a mixed solution of 0.75% potassium dihydrogen phosphate solution, 0.25% zinc sulfate solution and 0.25% ferrous sulfate solution, and spray 105 kg of mixed solution per mu. Spray once every 8 days and spray 3 times in a row. After the peanuts were harvested in autumn, the yield per mu reached 595 kg, and the yield per mu increased by 13%.
