Microbial organic fertilizer for preventing and treating apple tree canker and preparation method thereof

Abstract

The invention discloses a microbial organic fertilizer for preventing and treating apple tree canker. The fertilizer is prepared from peanut press pulp, molasses, yeast waste liquor, rice bran, radix astragali, self-heal, Herba Patriniae, taraxacum, Mangnolia officinalis, garlic, a composite fermentation strain and a composite fermenting enzyme. The invention also discloses a preparation method of a microbial organic fertilizer for preventing and treating apple tree canker. The preparation method comprises the steps of multistage fermentation, aging and the like. The microbial organic fertilizer for preventing and treating apple tree canker can effectively treat apple tree canker, effectively inhibit harmful pathogenic bacteria and has certain prevention effects on disease incidence of healthy apple trees. Besides, the fertilizer is capable of promoting growth and development of apple trees and reducing the consumptions of the pesticide and chemical fertilizer, has the advantages of protecting the ecological environment and enhancing the resource reutilization rate, and has favorable economic benefits 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 apple tree rot and a preparation method thereof. Background technique [0002] Apple rot is commonly known as rotten skin disease and stinky skin disease, which is an important disease of apple trees in northern my country. It mainly damages fruit trees that are more than 6 years old, causing tree vigor to weaken, branches to die, dead trees, and even garden destruction. It is common in North China, Northeast China and Northwest China. Apple rot is a weak parasite, and any factor that can cause tree vigor to weaken can induce apple rot. The disease has two expansion peaks in one year. That is, from March to April and from August to September, spring is more important than autumn. When the tree vigor is strong and the nutritional conditions are good, the disease is mild. When the tree vigor is weak, ...

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.
