Comprehensive prevention and control method for insect attack of tobacco field

Abstract

The invention discloses a comprehensive prevention and control method for insect attack of a tobacco field and relates to the technical field of tobacco field insect attack prevention and control. Themethod comprises the following steps: maintaining soil of the tobacco field, namely after winter ploughing of the tobacco field, performing spring raking; forming an isolation belt of the tobacco field, namely planting aphid luring plants around the tobacco field; additionally arranging trappers in the tobacco field, namely uniformly disturbing the trappers in the tobacco field after tobacco seedlings are transplanted; breeding insects in the tobacco field; and spraying a protection liquid to surfaces of tobacco leaves. By adopting the method, the problems that in conventional techniques, injurious insects are prevented and controlled at later stages, but the influence that the injurious insects are resulted on the basis of soil environments in tobacco fields is neglected; insects propagated through golden leaf sophora japonica have limited injurious insect inhibition effects, then varieties of the insects are limited, and effective insect damage inhibition cannot be achieved; after full stomach, the insects lose inhibition to the injurious insects, and the injurious insects cannot be captured within a certain period of time; and the surfaces of the tobacco leaves can be gnawed bythe injurious insects passing through a tempting belt and entering the tobacco field, can be solved.

Description

technical field [0001] The invention relates to the technical field of pest control in tobacco fields, in particular to a comprehensive control method for pests in tobacco fields. Background technique [0002] Using chemical pesticides to prevent and control aphids in tobacco agriculture is still one of the most important control means and measures. For a long time, people have been accustomed to using pirimicarb and omethoate to prevent and control aphids, resulting in the continuous increase of drug resistance of aphids and the killing of a large number of natural enemies. Due to the extensive use of chemical pesticides, ecological damage and environmental pollution have become major obstacles to agricultural production. It is an important task to restore the ecological balance and virtuous circle and promote the development of agricultural production by using the principles of ecology. Significantly reducing the use of chemical pesticides has important ecological signif...

Problems solved by technology

[0012] Aiming at the deficiencies in the prior art, the present invention provides a method for comprehensive prevention and control of tobacco field pests, which is used to solve the problem of controlling pests in the later stage in the traditional technology, but ignoring the fact that the generation of pests is based on the influence of the soil environment in the tobacco field; through The insects propagated by Sophora japonica have limited inhibitory effect on pests, which makes it impossible to effectively inhibit pests due to the limitation of insect species; after the insects are full, they lose the inhibition of pests, making it impossible to capture pests within a period of time; When pests pass through the trapping belt and enter the interior of the tobacco field, they are easy to gnaw on the surface of the tobacco leaves
