Embodiment Construction

[0011] Select 50 mu of tobacco perennial planting field as the experimental site, pour enough root water when transplanting the tobacco seedlings, and implement according to the following plan according to the condition of the seedlings, the fatness of the tobacco field, and the severity of the disease:

[0012] Option 1: On the 15th to 30th day after transplanting, if the disease is mild, spray 150 g of urea mixed with 20 kg of water on the leaves, and apply 20% virus WP 800 times liquid once combined with spraying. If the disease is severe, potassium nitrate and zinc nitrate should be used in a mass ratio of 1:1, and 3.5 kg mixed with 150 kg of water should be used to irrigate the roots and fertilize to supplement the nutrition of the tobacco plants in time. Foliar spray.

[0013] Option 2: On the 15th to 30th day after transplanting, if the disease is severe and the growth of tobacco seedlings is poor, use potassium nitrate and zinc nitrate in a mass ratio of 1:1, add 3.5kg...

Abstract

The invention relates to a method for preventing and controlling a mosaic disease based on improving tobacco plant nutrition resistance. The method comprises the following steps of: fully irrigating root fixing water in transplanting; planting tobacco till a fast growing period after the transplanting; for tobacco fields with low incidence, spraying urea on leaf surfaces, and applying 20 percent virus special wettable powder by combining the spraying; and for tobacco fields with high incidence, irrigating roots and applying additional fertilizers by potassium nitrate and zinc nitrate, applying the 20 percent virus special wettable powder by combining the leaf surface spraying, and spraying the urea on the leaf surfaces. After the proposal is carried out, the disease incidence of the tobacco mosaic disease in the fields is reduced to 10 percent from 90 percent before the disease is controlled, the disease index is reduced to 7.4 from 82.7, the yield can reach 85 percent of that of a normal tobacco field, the economic benefit can reach over 80 percent of that of the normal tobacco field, and the method has wide popularization value.

Description

technical field [0001] The invention relates to the technical field of crop disease prevention and control, in particular to a method for preventing and treating tobacco mosaic disease based on improving the nutritional resistance of tobacco plants. Background technique [0002] In recent years, tobacco mosaic disease has generally occurred in the main tobacco-producing areas of my country, and the damage is very serious. The incidence rate is generally 15% to 30%, and the incidence rate is as high as 60% to 90% in some tobacco areas. It is one of the most threatening malignant diseases restricting my country's tobacco production. [0003] Due to the variety of viruses that cause tobacco mosaic disease, the disease often occurs in the form of compound infection in the field, and the virus transmission routes are complex and diverse, and the survival time in the soil and diseased residues is long. The implementation of the means has brought many difficulties, and the use of ch...
