A method of mechanized prevention and control of grassland rodents

Abstract

The invention provides a method for mechanically preventing and controlling rodent damage in grassland. When the rodent damage is mainly caused by superficial layer activity rodent animals such as ochotona alpina, a disc harrow is used in a corresponding region for scarification at the depth being 15cm to 25cm; meanwhile, 45-90-degree repeated operation is performed; when the rodent damage is mainly caused by deep layer activity rodent animals such as zokors, the disc harrow is used for scarification at the depth being 10cm to 15cm; repeated operation is respectively performed after 10 days and 20 days; the operation in each time has 60-degree differences from the former time. The prevention and control method has the advantages that the utilization is simple; an instrument capable of realizing large-scale operation performs proper interference on the grassland; principles of bioinformatics and ecological niche and the like are used for controlling the rodent population density in a proper range so as to achieve the goals of reducing the rodent damage and protecting the grassland.

Description

technical field [0001] The invention relates to a method for preventing and controlling grassland rodent damage by mechanization, which belongs to the technical field of machinery. Background technique [0002] Rodent infestation is one of the main causes of grassland degradation, and rodent infestation control is an important content of grassland protection. The traditional control methods of grassland rodents mainly include physical, chemical and biological means, but the existing control methods have certain disadvantages, which are specifically reflected as follows: [0003] 1. High input cost: Traditional methods of rodent pest control require a lot of labor, because the layout of rodent traps (physical control), the introduction of poisonous traps (chemical control) and the introduction of natural enemies (biological control) are mainly done manually, and the work speed is slow and difficult. Widely used in grassland rodent control. [0004] 2. Chemical residues and ...

AI Technical Summary

Problems solved by technology

[0013] The invention provides a mechanized method for preventing and controlling grassland rodents, which can overcome the disadvantages of high cost and poor ecological benefits of traditional rodent control methods, and fully consider the heterogeneity of grassland, the behavior of rodents and their role in the grassland ecosystem. The ecological function in the grassland, using appropriate human disturbance and the principle of biological competition and survival, to achieve effective grassland rodent control, while improving the grassland soil structure, it can also provide a working platform for grassland reseeding, fertilization, etc.
