Preparation method for composite continuous cropping resistant agent specially used for strawberries

Abstract

The invention especially relates to a preparation method for a composite continuous cropping resistant agent specially used for strawberries, which belongs to preparation of microbial compound agents. The method comprises the steps of preparation of a Streptomyces microflavus antibiotic microbial agent, preparation of a trace element additive and preparation of the composite continuous cropping resistant agent specially used for strawberries by compounding microbial fertilizer biological potassium-phosphorous composite fertilizer, the Streptomyces microflavus antibiotic microbial agent and the trace element additive in propotion. The invention enables the problems of high cost, high toxicity and the like caused by utilization of the chemical method of fumigating for controlling replant disease of strawberries in the prior art to be overcome and allows microecological environment of soil to be improved and the nutrient elements of phosphorous and potassium needed for growth of strawberries to be provided. Application of the special continuous cropping resistant agent prepared in the invention in planting of strawberries enables yield increase to be effectively realized and soluble solid, sugar content, sugar-acid ratio and other quality of strawberries to be improved.

Description

technical field

[0001] The invention belongs to the preparation of microbial compound preparations, in particular to a preparation method of a special compound anti-stubble agent for strawberries. Background technique

[0002] Strawberry berries are bright red, fragrant and juicy, sweet and sour, and rich in nutrition. They are regarded as treasures among fruits. At present, there are nearly 40,000 hectares of strawberry cultivated in the country, with an output of more than 200,000 tons. Strawberry cropping disease is an important problem in strawberry production. Research at home and abroad shows that the main cause of crop cropping is the lack of soil nutrients and soil-borne diseases. Strawberry cropping in the same field for 2 years generally reduces yield by 10-15% , The production will be reduced by 20%-25% for 3 years, and the production will be reduced by more than 40% for more than 4 years. In severe cases, the harvest may even be lost.
