Method for implementing agricultural prevention and control of cotton field spider mite

Abstract

The invention belongs to the technical field of agriculture and discloses a method for implementing agricultural prevention and control of cotton field spider mite. The cotton line spacing is 40cm, the row spacing is 15cm, the density is 11,000 plants per mu, interplanting of every four lines of cotton and one line of flax is performed, the flax line spacing is 1.6m, a line of flax is densely planted close to each ridge furrow in the field, and accordingly cotton spider mite can be prevented from spreading to the cotton field. By cotton and flax interplanting, agricultural prevention and control of the cotton field spider mite are realized, prevention and control cost is reduced, environmental pollution is abated, natural enemies are protected, and cotton planting benefits are increased; the cotton spider mite usually spreads from ridges to the cotton field in late May and can be blocked by dense flax plants, a cotton spider mite repelling function is achieved along with aging of flaxplants, the cotton field spider mite in interplanting with flax is reduced by 53% as compared with that in a monoculture cotton field, and prevention and control without pesticide application are realized; the cotton planting benefits can be increased after harvesting in late August, 40kg of flax seeds can be produced per mu, and the income of 240yuan / mu can be achieved.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a method for agriculturally preventing and controlling spider mites in cotton fields through rational interplanting. Background technique [0002] Currently, the closest prior art: [0003] Cotton field spider mite is an important pest that harms cotton, and its control is generally achieved through chemical control. Because of its small size, it is concentrated on the back of the leaves, which increases the difficulty of control. To achieve a good control effect, a large amount of pesticides are required, which increases the cost of pest control and causes environmental pollution. Large-scale spraying also kills the insects. Natural enemies were destroyed, and the cotton field ecosystem was damaged. [0004] It is of great practical significance to achieve the purpose of protecting natural enemies, reducing pesticides and increasing efficiency by studying effic...

AI Technical Summary

Problems solved by technology

[0006] (1) The conventional method of controlling spider mites in cotton fields is mainly chemical spraying, which is prone to chemical pollution

[0007] (2) Due to the small size of the insect, large occurrence, and hidden feeding, chemical spraying results in high control costs and reduces the benefits of cotton planting

[0008] (3) Chemical control is easy to kill natural enemies and damage the cotton field ecosystem

[0010] After a large number of cotton spider mites occur in cotton fields, if no practical control measures are taken, it will easily lead to a reduction in cotton production and reduce the economic benefits of cotton planting

However, the chemical pollution caused by spraying a large amount of chemical pesticides is unavoidable. At the same time, beneficial insects in cotton fields are sensitive to most pesticides. A small amount of pesticides can kill natural enemies and deteriorate the ecological environment of cotton fields.
