Application of composition containing kasugamycin and zinc thiazole to prevention and treatment of soft rot of dendrobium officinale

Abstract

The invention discloses application of a composition containing kasugamycin and zinc thiazole (the weight ratio of kasugamycin to zinc thiazole is 1: 7) to prevention and treatment of soft rot of dendrobium officinale, promotion of growth of dendrobium officinale plants and improvement of quality of dendrobium officinale, and also discloses a method for preventing and treating soft rot of dendrobium officinale, promoting the growth of the dendrobium officinale, and improving the quality of the dendrobium officinale. The growth of the dendrobium officinale is promoted by increasing the number of buds, increasing the plant height, increasing the number of longest bud leaves, promoting the leaf length and / or improving the sturdiness of stalks. The improvement of the quality of the dendrobium officinale is achieved by increasing the polysaccharide content of the dendrobium officinale.

Description

technical field [0001] The invention belongs to the field of agricultural technology, and specifically relates to the use of a composition containing kasugamycin and thiazole zinc for preventing and treating soft rot of Dendrobium candidum, and simultaneously promoting the growth of Dendrobium candidum plants and improving the quality of Dendrobium candidum, and a method for treating soft rot of Dendrobium candidum Comprehensive approach to prevention and control.

Problems solved by technology

[0005] At present, there are some problems in the prevention and control measures of Dendrobium candidum soft rot, for example: 1) Dendrobium candidum soft rot is a soil-borne disease, which mostly harms the base of the stem. Copper preparations are commonly used as bactericides because of poor or no systemic absorption. And result in poor effect, and there are crop safety problems, easy to produce phytotoxicity; 2) Dendrobium officinale is a precious Chinese herbal medicine, when choosing a medicament, special attention should be paid to choosing a safe and environmentally friendly medicament. The problem has been banned, resulting in fewer available agents for Dendrobium officinale soft rot, while biological agents are slow to take effect; 3) Dendrobium officinale is often infected with a variety of fungal diseases and mixed diseases of soft rot, and the existing fungicides can be mixed Poor, separate prevention and treatment is time-consuming and laborious
