Embodiment Construction

[0026] The field that the present invention implements is mainly paddy field, and bullfrog habitat pool, frog shed, drainage ditch, field ridge and fence are set in the field, wherein the size of bullfrog habitat pool and the number of drainage ditches will be determined according to the size of paddy field area, generally Next, the area of ​​the bullfrog habitat pool accounts for 1%-2% of the total area of ​​the paddy field, and the distance between the drainage ditches is 10-20 meters. The basic principle of bullfrogs to control field pests: Bullfrogs are carnivorous animals with a wide range of food, and the number of swallowed crop pests accounts for 82%, including borer moths, locusts, mole crickets, water fleas, fly maggots and various insects. Therefore, breeding bullfrogs in the field can effectively control insect pests and reduce the use of chemical agents.

[0027] With reference to accompanying drawing: the field that the present invention implements is mainly by f...

Abstract

A method for using Rana catesbeiana to control pests in paddy fields includes: fencing a paddy field of certain area; digging drainage ditches on the paddy field, wherein the drainage ditches lead to an inhabiting pond for Rana catesbeiana, and the inhabiting pond accounts for 1-2% of total area of the paddy field; setting up a supported shed above the inhabiting pond; mounting efficient trap lamps on the supported shed; and putting Rana catesbeiana in the paddy field to breed. Rana catesbeiana belongs to carnivorous animals and take food in a wide range, crop pests taken by Rana catesbeiana account for 82% of total food taken by Rana catesbeiana and include snout moth, grasshopper, mole cricket, water flea, fly larvae and other insects, and accordingly, the pests are controlled effectively, and chemicals for use are reduced. By the method, pollution and destruction of plants and fields by chemical pesticides are avoided, ecological environment and physical health of people are protected, increase of rice yield can be achieved, Rana catesbeiana can be reclaimed from the fields to serve as commodities, income of farmers is increased, and overall development of green and ecological agriculture is promoted.

Description

technical field [0001] The invention relates to the technical field of agricultural rice field pest control, in particular to a method for controlling rice field pests by using bullfrogs. Background technique [0002] my country is a large agricultural country, and the use of chemical agents is very common in the process of agricultural production. According to statistics, my country uses chemical agents to prevent and control an area of ​​about 4.8 billion mu every year, and the total value of losses that can be exchanged is about 55 billion yuan. It is undeniable that so far, compared with other methods and measures, chemical pesticides are still the most convenient, concentrated, effective, labor-saving and relatively reasonable allocation of social resources compared with other methods and measures. The dangers are also becoming increasingly apparent. First of all, it endangers human health and life; according to the World Health Organization (WHO) and Food and Agricult...
