Problems solved by technology

[0007] However, in the existing technology at present, the technical content and the direction of treatment of citrus huanglongbing are all focused on discovering the citrus psyllid, the vector of huanglongbing, and then eliminating it with drugs, or digging up the diseased tree and replanting it, but the result is new. The tree will be infected by the pathogen again soon, and the cause of the disease cannot be solved from the root

Embodiment

[0055] Such as figure 1 As shown, the citrus orchard planting method for preventing diseases and insect pests of the present invention, firstly, based on the fact that guava trees can naturally reproduce phytoseiids, guava trees and citrus trees are interplanted in a checkerboard pattern; guava trees are surrounded into a closed area After the guava tree forms a canopy, citrus is planted in the enclosed area surrounded by the guava tree, and each citrus is surrounded by guava trees to form a secondary protective barrier. populations of seid mites, allowing phytoseiid mites to eat citrus psyllids;

[0056] At the same time, it is supplemented by spraying mineral oil emulsion, and spraying mineral oil emulsion (180-230 times dilution) to the leaves of citrus trees; spraying mineral oil emulsion is sprayed 6-7 times a year, and because many phytoseiids like to come out at night to prey , in order to protect the phytoseiid population, spraying mineral oil emulsion is spraying dur...

Abstract

The invention belongs to the field of citrus planting, and particularly relates to a citrus orchard conducive pest control planting method. Guava fruiters are planted in a citrus orchard to increase the population quantity of phytoseiid mites in the citrus orchard, an independent environment is formed, citruses are planted, the periphery of each citrus tree is enclosed by the guava fruiters to form double barriers in a checkered manner, petroleum oils are sprayed in a matched manner, and pest control is fundamentally performed in the citrus planting process. According to the citrus orchard conducive pest control planting method, based on the capability of naturally breeding the phytoseiid mites by the planted guava fruiters, the guava fruiters and the citrus trees are planted in the checkered manner, the citruses are planted after the guava fruiters form crowns, and the petroleum oils are sprayed to control citrus tristeza viruses. The pest control function of natural enemies is a direct effective means for killing sole insect-borne citrus psyllas of citrus tristeza virus transmission pathogens in citrus planting.

Description

technical field [0001] The invention belongs to the field of citrus planting, in particular to a planting method for citrus orchards which is helpful for the prevention and control of diseases and insect pests. Background technique [0002] In the cultivation of citrus, citrus huanglongbing has always been a problem in the world. The only insect vector that spreads its pathogen is the citrus psyllid, so eliminating citrus psyllid is the primary task of eradicating citrus huanglongbing. [0003] Phytoseiid mite Acari:Phytoseiidae is one of the most effective predatory natural enemies known so far, and plays an important role in the ecological control of pest mites. Phytoseiid mites can not only prey on harmful mites such as spider mites, tarsal mites, and gall mites, but also small insects such as thrips, whitefly, aphids, and citrus psyllids. [0004] So far, many plants have planted seid mites as biological control factors in agricultural ecosystems or as important predato...
