A kind of method of preventing and treating the dead tree of Lycium barbarum root rot

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 Solanaceae family, which is an important economic plant resource for medicine and food. In recent years, with the continuous expansion of wolfberry planting scale, the occurrence of many 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 the soil, and the pathogenic bacteria are four kinds of Fusarium. F. oxysporum, F. solani, F. concolor and F. moniliforme, among which F. oxysporum is the most pathogenic, followed by F. oxysporum Fusarium solani, Fusarium homochromia and Fusarium moniliforme are weak pathogens. After the onset, the roots and necks of the diseased plants rot, and the vascular bundles of the stems turn br...

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
