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%.

Abstract

The invention provides a fertilizing method for peanuts planted in hilly and mountainous regions, comprising the following steps: utilizing a common macroelement fertilizer, a composite fertilizer with sustained and controlled release, a medium element calcareous fertilizer, a microelement molybdenum fertilizer and a boron fertilizer as the base fertilizers, evenly mixing the fertilizers when sowing, and applying all the fertilizers at a time; spraying a foliar fertilizer when the peanuts are in the pod setting stage so as to provide nutrients for later growth of peanuts. The invention enables effective solving of the problems of imbalanced soil nutrition, insufficient nutrition in later growth stages of peanuts and low output in planting peanuts in hilly and mountainous regions due to the difficulty in applying organic fertilizers.

Description

technical field [0001] The invention discloses a method for fertilizing peanuts in hilly areas, belonging to the technical field of high-yield fertilization for peanuts. Background technique [0002] Peanut is an important oil crop and economic crop in China. In 2009, 65.6498 million mu of peanut was planted in my country, with a total output of 14.7079 million tons and a yield of 224.04 kg per mu. Peanuts are resistant to drought and barrenness, and have strong adaptability. In the hilly and thin fields with poor conditions, the yield of crops such as corn is very low, but peanuts can achieve better harvests. Under the same production conditions, compared with other crops, planting peanuts not only requires more investment in seeds, but also requires less management labor, less fertilizer, and higher efficiency. It can also improve the soil and increase the output of subsequent crops. The income per unit area of ​​peanut planting is significantly higher than that of most o...
