Dedicated peanut fertilizer for maize-peanut intercropping and preparation method of dedicated peanut fertilizer

Abstract

The invention provides a dedicated peanut fertilizer for maize-peanut intercropping. The dedicated peanut fertilizer is prepared from the following raw materials by weight: 323 parts of 0.5% polymer-coated urea, 75 parts of urea, 311 parts of double superphosphate, 250 parts of potassium sulfate, 260 parts of decomposed, fermented deodorized and dried livestock excrement, 10 parts of zinc sulfate, 10 parts of ammonium molybdate, 10 parts of magnesium sulfate, 10 parts of borax, 70 parts of humic acid, and 3 parts of an NAM additive. According to the absorption and utilization rule of main nutrients of peanuts in a maize-peanut intercropping system, different slow-release and controlled-release materials are added into a common fertilizer, accurate compounding is carried out, the properties of soil are improved by utilizing an organic fertilizer and humic acid, so that the defect that the input cost of a controlled-release fertilizer is over high is solved, soil is improved, one-pass fertilizing for peanut sowing is realized, and fertilizer deficiency at a later stage can be avoided.

Description

technical field [0001] The invention relates to the field of fertilizer production, in particular to a formula and a preparation method of a special peanut fertilizer under the condition of corn and peanut intercropping. Background technique [0002] For a long time, in order to meet people's growing needs, my country's agricultural production has blindly pursued production and applied a large amount of chemical fertilizers and pesticides, resulting in low utilization rate of chemical fertilizers, large losses, serious pollution of farmland and water bodies, weakened crop resistance, aggravated pests and diseases, and poor crop quality. deterioration, and the deterioration of the agricultural ecological environment. Therefore, how to increase crop yields, reduce the amount of chemical fertilizers and pesticides used, and achieve environmentally friendly and sustainable agricultural development has become an urgent problem to be solved. Intercropping is the essence of traditi...

AI Technical Summary

Problems solved by technology

This type of special peanut fertilizer is applied in the corn-peanut intercropping system. The content of nitrogen and phosphorus is insufficient, and the ratio is not suitable, which will easily lead to insufficient absorption and utilization of nitrogen and phosphorus fertilizers for intercropping peanuts, which is not conducive to the growth of peanuts.
