Cultivation method for improving disease resistance of tobacco

Abstract

The invention discloses a cultivation method for improving the disease resistance of tobacco. 50-150 kg of soil improvement particles are applied per mu, when tobacco seedlings are transplanted, the roots of tobacco seedlings are irrigated with a prepared agent liquid, and the root of each tobacco seedling is irrigated with a 35ml Likujing liquid, and the roots of tobacco seedlings are thoroughlyirrigated with water after transplanting; and foliar fertilizer is sprayed on leaves every day 1-5 days after tobacco transplantation. The soil improvement particles are sprayed on the land during thesoil preparation, which can prevent pathogen infection caused by contaminated soil or humus to tobacco surfaces. Before the tobacco surfaces are transplanted, the roots of the tobacco seedlings are irrigated by the agent liquid, the foliar fertilizer can promote the process of growth and metabolism of leaves, promotes the vigorous growth of leaves, timely supplement beneficial bacteria to avoid breeding of harmful bacteria and ensure the prevention and control effects, the disease resistance of tobacco can be effectively improved, and the incidence of tobacco bacterial wilt is significantly reduced, tobacco quality can be improved, and no effects on tobacco yield are avoided.

Description

technical field [0001] The invention relates to the technical field of tobacco planting, in particular to a cultivation method for improving disease resistance of tobacco. Background technique [0002] Tobacco bacterial wilt is a common disease that harms tobacco. Its typical symptoms are withered tobacco leaves, blackened and rotten roots, etc. Tobacco bacterial wilt is caused by bacterial infection, and the pathogens are mainly in the soil and left in the soil. In terms of residues, the main factors for the occurrence of bacterial wilt include soil, climate, fertilizer and fertilization measures, water conservancy conditions, and drought and flood resistance measures. [0003] Tobacco bacterial wilt has a great impact on tobacco production. At present, there is no effective prevention method. The method of simple chemical drug control has short validity period, poor stability, and serious pollution. Generally, soil improvement, water and fertilizer control, etc. need to be...

Problems solved by technology

[0003] Tobacco bacterial wilt has a great impact on tobacco production. At present, there is no effective prevention method. The method of simple chemical drug control has short validity period, poor stability, and serious pollution. Generally, soil improvement, water and fertilizer control, etc. need to be prevented and alleviated. The occurrence of dead leaves of tobacco reduces the impact of dead leaves on tobacco planting, so there is an urgent need for a cultivation method to improve tobacco disease resistance
