Mixed compound fertilizer for green soy bean planting and preparation method thereof

Abstract

The invention relates to the field of disease and pest control, in particular to a mixed compound fertilizer for green soy bean planting and a preparation method thereof. The mixed compound fertilizercomprises an improver, a decomposed organic fertilizer, a base fertilizer, paraffin and modified zeolite powder, wherein the improver comprises 3-5 parts of turfy soil, 4-5 parts of fly ash, 15-20 parts of medical stone powder, 4-5 parts of methyl methacrylate, 3-5 parts of zinc gluconate, 1-2 parts of ginger oil, 1-2 parts of sodium tripolyphosphate and 0.1-0.2 part of astragalus polysaccharide.The invention has the beneficial effects that the base fertilizer is coated with paraffin and modified zeolite powder, so that the loss speed of fertility can be reduced; the nutrients required by green soybeans can be adjusted through the base fertilizer, through arrangement of decomposed organic fertilizer, the retention time of the fertility can be further prolonged, and the loss of the fertility is reduced; in addition, by arranging the modifier, the fertility environment of the soil can be improved, and the modifier can be matched with modified zeolite powder to adjust the acidity and alkalinity of the soil.

Description

technical field [0001] The invention relates to the technical field of edamame planting, in particular to a mixed compound fertilizer for edamame planting. Background technique [0002] Edamame, commonly known as soybeans and soybeans, is the seed of Papilionaceae soybean, an annual herbaceous crop, 30-90 cm high, thick stems, square rhombus; pods are rectangular, flat, 5-6 cm long, drooping, on the pod Dense yellow slender bristles; 2-4 seeds, flat oval-shaped oval when fresh, 0.8-1.5 cm long, light green, yellow, yellow-green or purple-black when dry. In order to increase the yield of edamame, it is necessary to fertilize edamame during the planting process to obtain sufficient nutrition. The compound fertilizers in the prior art cannot meet the normal growth needs of edamame due to their rapid loss of fertility, and increasing the frequency of fertilization will easily accelerate the compaction of the soil, which is not conducive to the sustainable use of land.
