Preparation method of biological fertilizer for improving soil for continuous cropping of strawberries

Abstract

The invention discloses a preparation method of a biological fertilizer for improving soil for continuous cropping of strawberries. Microbial fermentation broth, crushed waste straw, sugar industry filtered mud, decomposed manure, a traditional Chinese medicine extract product, leguminous plant root, stem, leaf and shell wastes, domestic fungus dregs, and a cake fertilizer are used as raw materials; fermentation, disinfection, granulation and a series of methods are used for preparing the biological fertilizer for improving soil for continuous cropping of strawberries. The fertilizer can induce strawberry plants to generate acquired systemic resistance and enhance disease resistance; at the same time, the fertilizer can adjust microorganism and soil animal class groups in rhizosphere soil, reduce quantity of pathogens, increase quantity of beneficial organisms, build good soil environment for growth of strawberries, and establish soil and nutrition adjustment for overcoming strawberry continuous cropping obstacles; after the fertilizer is applied to the soil for plantation of strawberries, plant death rate is reduced, yield is increased, generation probability of insect diseases is reduced, and the big problem of sustainable plantation of strawberries is solved.

Description

technical field [0001] The invention relates to strawberry planting biological agent technology, in particular to a preparation method of biological fertilizer for improving strawberry continuous cropping soil. Background technique [0002] Due to the high moving cost of strawberry greenhouse facilities, the long annual production and use period (greenhouse strawberry is about 9 months from planting to the end of harvesting), coupled with limited cultivated land, it is difficult to rotate crops, and continuous cropping in facilities is very common, which causes soil pollution. The pathogenic bacteria and insect eggs in the shed have accumulated year after year, and some soil-borne diseases and insect pests such as Verticillium wilt and anthracnose have occurred year after year, and the disease has become more and more serious. The growth and development are stunted, the mortality rate is as high as 30%, and the output decreases by 20%-50%, which causes huge losses to strawbe...
