Example Embodiment

[0016] A method for preventing and controlling rice pests by raising frogs in rice fields, the method comprising:

[0017] Paddy field management: insert the previously cultivated seedlings into the paddy field, the interval between each seedling is 23 ~ 26cm, the seedlings are inserted into the soil at a depth of 5 ~ 10cm, the height of the water layer of the paddy field is not less than 2cm; ditches and paddy fields are set around and in the middle of the paddy field The width of the surrounding ditch is 40~60cm, the ditch depth is 20~30cm, the width of the middle ditch of the paddy field is 20~40cm, and the ditch depth is 10~25cm;

[0018] Set up a frog habitat: pile up a number of 10-30cm above the water surface in the middle of the paddy field, with an area of ​​1-2m 2 The earth pusher is equipped with trap lights on the mound, and the soil around the field is piled up 10-30cm above the water surface with a slope of 15-30° for artificial feeding of food;

[0019] Install anti-es...

Abstract

The invention discloses a method for preventing and controlling rice pests by breeding frogs in a rice field. The method mainly comprises the following steps: managing a rice field; setting an inhabiting place for the frogs; arranging anti-escape instruments; selecting frog varieties; performing fertilization management in a period of breeding the frogs; harvesting rice and releasing the frogs. By adopting the method for preventing and controlling rice pests by breeding the frogs in the rice field, the condition of pesticide spraying is reduced; the frogs as natural enemies of rice pests are introduced, so that common rice pests such as rice plant hoppers can be effectively killed and inhibited; the rice field is arranged reasonably, so that the environment is suitable for the frogs to grow; the excrement of the frogs can improve the fertility of the rice field, so that healthy growth of the rice is promoted, and a beneficial ecological cycle is formed.

Description

technical field [0001] The invention belongs to the field of biological control of rice pests, and in particular relates to a method for controlling rice pests by raising frogs in paddy fields. Background technique [0002] my country is a country with large rice production and consumption. Rice cultivation has a history of more than 7,000 years in my country. Rice is the main food crop in southern my country, and rice pests are an important factor affecting rice output and quality. At present, there are about 250 kinds of rice pests recorded in my country, among which rice planthoppers (BPH, white-backed planthopper, and brown planthopper), rice leaf rollers and stem borers (Chilorrhizae, large borer) etc. In order to increase the yield of rice, people take various measures against pests, and most of them still adopt the method of spraying pesticides. Although this method is simple, it will cause soil pollution, water eutrophication and other problems. [0003] Biological...
