Zokor bow and arrow

Abstract

The invention discloses a zokor bow and arrow. The zokor bow and arrow comprises a bow bod, a string, a lever, a vertical line, a contact and an arrow body, the bow body is in an arc shape of which the arc surface faces downwards, the string comprises a connecting ring and a string body, and the connecting ring is connected to the upper portion of the middle of the string body and is connected byseveral annular structures; one end of the lever stretches into the annular structure at the uppermost portion and is in contact with the top in the ring, the lever is connected with the vertical lineat the upper portion of the pivot, the upper end of the vertical line is connected to the inner side of the bow body, the other end of the lever is connected with the contact, the contact comprises acontact part and a connecting part, the connecting part is connected to the end of the lever, the lower end of the contact part is inserted into a hole in the lower portion of the bow body, and the downward tail of the arrow body is located at the string body and the connecting ring. The zokor bow and arrow is convenient to produce in batches, the quantity of alpine grassland zokors is conveniently and effectively controlled, and a simple and feasible method is provided for ecological protection. The zokor bow and arrow is simple in manufacturing technology, low in cost, high in efficiency and easy to popularize.

Description

technical field [0001] The invention belongs to the technical field of agricultural rodent control tools, and relates to a zokor bow and arrow. Background technique [0002] The ecological environment of my country's Qinghai-Tibet Plateau is fragile, vulnerable to damage, and difficult to restore. It is the key to my country's ecological security barrier, the source of my country's water resources, and a strategic resource related to the national economy and people's livelihood. Therefore, my country has invested a lot in the Qinghai-Tibet Plateau. ecosystem. The Sanjiangyuan is the birthplace of the Yangtze River and the Yellow River. In recent years, due to long-term overloaded grazing in the Sanjiangyuan, serious degraded patches such as black soil flats have appeared. With the decrease of vegetation coverage, the grassland has degraded, and the number of rodents has increased rapidly, further accelerating grassland. Degradation and the two promote each other, forming a s...

AI Technical Summary

Problems solved by technology

[0003] Zokors are large rodents that live underground for a long time and eat the roots of plants, resulting in the death of a large area of ​​vegetation. The soil is exposed on the surface, causing soil erosion

Therefore, the large number of zokors has caused serious grassland degradation and soil erosion.

However, the current methods of controlling the number of zokors are limited. Drug resistance is easy to form through drug rodent control, and the population of zokors rebounds. At the same time, a large amount of manpower and material resources are invested, and the effect is small; the biological control method of feeding natural enemies has a long period of existence. Disadvantages of large investment and slow effect
