Abstract

The invention discloses a method for preventing field tobacco virus disease by protective cultivation measures, and relates to the technical field of tobacco field virus disease control. The method comprises the following steps: protection of seedling main bodies: a seedling greenhouse is completely covered with an aphid prevention net after being built; protection and maintenance of agriculturalmanagement: a tobacco field is subject to clean production; implementation of soil testing and formulated fertilization, and controlling fertilization dosage; comprehensive application of control measures: comprehensive control is performed by cooperation of agricultural control, physical control, biological control and chemical control. The existing main problem that how to cut off and reduce thevirus disease spread approach of aphids to achieve the main technical means of aphid avoidance due to the lack of effective treatment and remedy means in the traditional technology is solved.

Description

technical field [0001] The invention relates to the technical field of tobacco field virus disease prevention and control, in particular to a method for preventing field tobacco virus disease through protective cultivation measures. Background technique [0002] my country is the largest tobacco producer in the world today, and tobacco is an important economic crop in my country. There are many kinds of tobacco pests and diseases, which are very harmful to tobacco production.
