Microbial organic fertilizer for preventing and treating peach leaf curl and preparation method thereof

Abstract

The invention discloses a microbial organic fertilizer for preventing and treating peach leaf curl, made from the following materials: tea leaf dregs, rice bran, soybean meal, straw, humic acid, Radix Astragali, Spica Prunellae, Flos Lonicerae, dandelion, complex trace elements, composite fermenting bacteria and composite fermentation enzymes. The invention also discloses a preparation method of the microbial organic fertilizer for preventing and treating peach leaf curl, comprising the steps such as multistage fermenting and aging. The microbial fertilizer for preventing and treating peach leaf curl according to the invention can effectively prevent and treat peach leaf curl, effectively inhibit germs and can also prevent healthy peach trees from infecting peach leaf curl; in addition, the fertilizer can also promote growth and development of peach trees, enables reduced usage of pesticides and chemical fertilizers, has the advantages of protection of ecological environment and increased reutilization rate of resources, and has good economic and social benefits.

Description

technical field [0001] The invention relates to the field of pesticides and chemical fertilizers, in particular to a microbial organic fertilizer for preventing and treating peach leaf shrinkage disease and a preparation method thereof. Background technique [0002] Leaf shrinkage of peach trees mainly damages leaves, and can also damage flowers, young fruits and new shoots in severe cases. When the young leaves are just stretched out, they appear curly and red in color. The leaves gradually develop, and the degree of curling and shrinkage increases, resulting in corrugated bumps on the whole leaf, and in severe cases, the leaves are completely deformed. The diseased leaves are relatively hypertrophic, with uneven thickness, crisp texture, light yellow to reddish brown; in the later stage, a layer of off-white powder grows on the surface of the diseased leaves, which is the ascus layer of the pathogen. Diseased leaves eventually dry up and fall off. The spores can resist ...

Problems solved by technology

Although it has a certain effect on increasing production and income, long-term use will cause soil acidification and compaction, resulting in poor water retention, fertilizer retention, and air permeability of the soil, and less organic matter; secondly, it will cause excessive accumulation of harmful chemical residues in the soil. Being directly absorbed by plants has caused heavy metals in crops to seriously exceed the standard, affecting their growth and development

Due to poor air permeability after soil compaction, some fertilizers and pesticides are discharged into rivers and lakes or residual soil and crops, reducing the utilization rate of fertilizers, not only causing waste of resources, but also destroying the agricultural ecological environment and endangering the safety of humans and animals.
