[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

Embodiment 1
[0035] A cultivation method for improving tobacco disease resistance, comprising the steps of:
[0036] Step 1: Soil Amendment
[0037] In the spring of the next year, select suitable land for site preparation, apply 50-150 kg of soil improvement particles per mu, and then perform deep plowing, ridge preparation, and drainage ditches; when ridge preparation is performed, the distance between ridges is 100-130 cm, and the height of ridges is 35-30 cm. .
[0038] The soil improvement particles include quicklime, biochar and wheat straw particles, and the quicklime, biochar and wheat straw particles are mixed according to the ratio of 1:1:1; the quicklime, biochar and wheat straw particles are dried at 120°C for 6 hour, crushed through a 60 mesh sieve to obtain a fine powder.
[0039] Step 2: Preparation of liquid medicine
[0040] Likujing and water are prepared into Likujing medicinal liquid according to the weight ratio of 1:1500;
[0041] Step 3: Tobacco Transplanting

Embodiment 2
[0055] Comparative Test
[0056] Rotate the land with flat terrain, convenient irrigation and drainage, and moderate fertility, respectively adopt this method to process 200 tobacco seedlings and mark it as group A, and select 200 same tobacco seedlings in the same plot as the control group to mark it as group B, Conduct a comparative test. The distance between the plots of Group A and Group B shall not be less than 5 kilometers, and no tobacco shall be planted between Group A and Group B.
[0057] The sample method is as follows:
[0058] Group A, the following steps are taken:
[0059] Step 1: Soil Amendment
[0060] Apply 50-150kg of soil improvement particles per mu, and then carry out deep plowing, ridge preparation and drainage ditches; when ridge preparation is performed, the distance between ridges is 100-130cm, and the height of ridges is 35-30cm.
[0061] Soil improvement granules include quicklime, biochar and wheat straw granules, which are prepared by mixing q...

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...
