A kind of ginger coating method of compound medicine

Abstract

The invention discloses a method for coating ginger with a compound medicine, which comprises the steps of screening ginger tubers, preparing a compound medicine, coating treatment of the ginger tubers, and bagging. The method for coating the ginger seed with the compounding agent disclosed in the invention is specially aimed at the disease of the seed ginger, and adopts specific oomycete fungicides, fungicides, insecticides, and plant growth agents, and the final concentrations are respectively 0.15% to 0.2%, 0.025~0.2%, 0.2%~0.4%, 0.2%~0.3% compound medicine, make coating agent, through spray coating and other measures, form a medicinal film on the surface of the ginger tuber, on the one hand kill the ginger Accumulated pathogens in the surface and surface xylem, on the other hand, it can also prevent the invasion of soil-borne pathogens and the destruction of insect pests, effectively kill the pathogenic bacteria accumulated in the tubers of ginger, and prevent soil-borne diseases during the budding process of ginger. It also promotes the root development of ginger and improves the disease resistance of ginger during its growth.

Description

technical field [0001] The invention belongs to the technical field of ginger seed ginger treatment methods, and relates to a method for coating the seed ginger with a compound medicine. Background technique [0002] During the asexual reproduction of ginger, a large number of pathogenic bacteria will accumulate on the surface of ginger tubers, such as Pythium, Phytophthora, Fusarium, Anthrax, Coccidioides and Rhizoctonia. Germination, infection of ginger roots, stems, and vascular bundles, and development from bottom to shoot tip, resulting in serious diseases such as root rot, stem base rot, and withering of ginger seedlings that lead to plant death, and severe anthracnose, leaf spot, and verticillium on leaves. and other diseases, resulting in the reduction of ginger production and quality. After the seedlings germinate in the soil, the young shoots are often harmed by insects such as cutworms, earthworms, aphids, mole crickets, and grubs, resulting in the death of the y...

AI Technical Summary

Problems solved by technology

[0004] At present, the treatment methods for the tubers in the process of asexual reproduction of ginger mainly include: (1) directly planting the tubers of ginger in the soil without any treatment; The disease spreads in a large area in the field, resulting in the destruction of the field, reduced yield or even no harvest; (2) the tubers are first germinated and then planted in the soil; although this method has improved disease resistance compared with the first method, it still remains after the disease. There is at least a quarter of the ginger loss, which has a great impact on ginger farmers

At present, in the traditional ginger cultivation process, there is no ginger disinfection and rooting promotion treatment.

[0005] And immerse the roots of ginger tubers in pesticides, this method can improve the ability to resist diseases in the short term, but the long-term effect is short, and the long-term damage prevention effect is poor. High moisture content and rotting, therefore, need to choose a new application method

At present, traditional single fungicides or mixtures of several fungicides are mostly used in pesticides, and the types are limited, and the traditional fungicides have been used for a long time, and the disease has developed strong drug resistance. Therefore, the disease prevention effect is not only poor, but also leads to Problems such as soil pollution need to be improved urgently; therefore, screening new fungicides and insecticides is the trend of technological development

[0006] Coating treatment is mostly applied to seed plants, but seldom used in vegetatively propagated tuber plants; at present, there are few treatment methods for coating ginger tubers, mainly first dipping ginger tubers in pesticide solution or mixing medicament and The chemical agents are mixed and fixed on the seeds, and then the coated ginger tubers are wrapped with a tangible thin layer material. Although this treatment method is better than the direct seed soaking method, there are also differences in the concentration during coating. problems such as uniformity and cumbersome methods, and cannot promote the germination and growth of ginger

[0007] Therefore, in view of the easy accumulation of disease-causing diseases in ginger tubers, it is urgent to solve the problems of the current application of pesticide formulations with few types, poor effects, and poor effects of coating methods. Ginger industry develops healthily, increases yield, and achieves the goal of A-level production of ginger green food
