Use of composition containing kasugamycin and zinc thiazole for preventing and treating soft rot of Dendrobium officinale

Abstract

The invention discloses a composition containing kasugamycin and thiazole zinc (the weight ratio of kasugamycin and thiazole zinc is 1:7), which is used for preventing and treating soft rot of Dendrobium officinale, promoting the growth of Dendrobium officinale plants, and improving the quality of Dendrobium officinale purposes, and the present invention also discloses a method for preventing and treating soft rot of Dendrobium candidum, promoting the growth of Dendrobium candidum, and improving the quality of Dendrobium candidum. The growth promotion of Dendrobium officinale is obtained by increasing the number of buds, increasing the height of the plant, increasing the number of leaves of the longest bud, promoting the length of leaves and / or increasing the thickness of stems. The promotion of improving the quality of Dendrobium candidum is obtained by increasing the polysaccharide content of Dendrobium candidum.

Description

technical field [0001] The invention belongs to the technical field of agriculture, in particular to the use of a composition containing kasugamycin and zinc thiazole for preventing and treating the soft rot of Dendrobium officinale, simultaneously promoting the growth of Dendrobium officinale plants and improving the quality of Dendrobium officinale, and a kind of application of Dendrobium officinale soft rot. Comprehensive control method. Background technique [0002] Dendrobium officinale belongs to the orchid family, and its epidermis is iron green.

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
