Method for preventing and treating Chinese wolfberry root rot and preventing root rot-caused dead trees

Abstract

The invention relates to a method for preventing and treating Chinese wolfberry root rot and preventing root rot-caused dead trees. A composite microbial agent and a decomposed protein biological organic fertilizer act together to control the Chinese wolfberry root rot, and the use method comprises the following steps: applying the biological organic fertilizer base fertilizer formed by decomposing mushroom residues, to the planted Chinese wolfberry plant; and then applying the composite microbial agent to the planted Chinese wolfberry plant in the plant radius of 25 cm each year, wherein thecomposite microbial agent consists of a fermentation product of Bacillus amyloliquefaciens MES812 and a fermentation product of Bacillus subtilis MES810 in the volume ratio of 1: 1. The composite microbial agent and the decomposed protein biological organic fertilizer are mixed and used, so that the growth of pathogenic bacteria can be inhibited, the content of organic matters and mineral nutrients in the soil can be increased, the soil structure, the nutrient condition and the micro-ecological environment can be effectively improved, and the root rot-caused dead trees can be prevented, the survival rate of the Chinese wolfberry can be increased, the quality of the Chinese wolfberry can be improved, and the yield of the Chinese wolfberry can be increased.

Description

technical field [0001] The invention belongs to the field of agricultural biology, and relates to a method for preventing and curing wolfberry root rot and dead trees. Background technique [0002] Lycium barbarum is a perennial deciduous shrub of the family Solanaceae, and it is an important medicinal and edible economic plant resource. In recent years, with the continuous expansion of the planting scale of wolfberry, the occurrence of various diseases of wolfberry has also increased year by year, among which root rot is one of the main diseases. Lycium barbarum root rot is a disease transmitted through soil, and the pathogenic bacteria are four kinds of Fusarium. Fusarium oxysporum F.oxysporum, Fusarium solani F.solani, Fusarium oxysporum F.concolor and Fusarium moniliforme F.moniliforme, among which Fusarium oxysporum was the most pathogenic, followed by Fusarium solani, Fusarium moniliforme and Fusarium moniliforme are weakly pathogenic bacteria. After the onset, the ...

AI Technical Summary

Problems solved by technology

Due to root rot, the mortality rate of wolfberry is 2%-6% every year, and the incidence rate is as high as 40% in the most serious place, and the mortality rate is as high as 25%, which brings great losses to the planting and production of wolfberry.

At present, the methods to prevent and control the dead trees of Lycium barbarum root rot are mainly spraying pesticides, formula fertilization, and increasing the application of phosphorus and potassium fertilizers, which are time-consuming and laborious, pollute the environment, are toxic and harmful, and cannot effectively prevent the occurrence of diseases from the root. It has attracted more and more attention, but there is no report on the use of microbial agents and fertilizers to control wolfberry root rot
