Fruit tree insect prevention technology by aid of covers

Abstract

The invention belongs to the technical field of disease and insect pest prevention and control for fruit trees, and particularly relates to a fruit tree insect prevention technology by the aid of covers. The fruit tree insect prevention technology is characterized in that according to research findings on fruit setting characteristics of different varieties of fruit trees and activity rules of injurious insects on the fruit trees, when single fruit trees or in-line fruit trees or vast fruit trees which have different fruit setting characteristics and the injurious insects with different activity rules are specifically protected by the covers in proper periods, fruits can be isolated from the injurious insects and are effectively prevented from being harmed by the injurious insects, the photosynthesis of the fruit trees is hardly affected by selected cover materials, obvious influence of the selected cover materials on the temperature and the humidity required by each fruit tree is prevented, and a physical protection layer can be provided for each single fruit tree, the in-line fruit trees or the vast fruit trees; simple supports of the covers comprise upright columns (timber piles or steel tubes) and drawn steel wires, and the covers can be shifted as needed, can be operated easily and conveniently and are economical and durable. The fruit tree insect prevention technology has the advantages that dependence on pesticides for pest control and corresponding pesticide and labor cost input can be greatly reduced for fruit growers, the commodity rate of the fruits is increased, and the safety of the fruits is improved.

Description

technical field [0001] The invention belongs to the technical field of prevention and control of fruit tree diseases and insect pests, and more specifically relates to a fruit tree cover insect prevention technology. Background technique [0002] There are many kinds of fruit tree pests with different damage characteristics. Some borer pests with high reproduction coefficient, such as litchi borer and fruit fly larvae live in the fruit. They belong to "zero tolerance" pests and are difficult to control. Bring serious loss to fruit tree production. In this regard, producers at the present stage mainly use various chemical means to prevent and control, and the frequent and excessive use of various chemical agents not only improves the resistance of various pests and diseases, but also may kill the natural enemies of pests, and also It may cause excessive pesticide residues in fruit products and pollute the ecological environment, which have seriously affected the healthy deve...

Problems solved by technology

[0002] There are many kinds of fruit tree pests with different damage characteristics. Some borer pests with high reproduction coefficient, such as litchi borer and fruit fly larvae live in the fruit. They belong to "zero tolerance" pests and are difficult to control. Serious losses to fruit tree production

In this regard, producers at the present stage mainly use various chemical means to prevent and control, and the frequent and excessive use of various chemical agents not only improves the resistance of various pests and diseases, but also may kill the natural enemies of pests, and also It may cause excessive pesticide residues in fruit products and pollute the ecological environment, which seriously affects the healthy development of the fruit industry

The fruit bagging technology of single fruit or single ear can effectively solve this problem, but with the continuous increase of labor costs in recent years, bagging technology, as a labor-intensive technology, has been greatly restricted in its promotion
