Frog-rice co-culture ecological high-yield breeding-planting method

Abstract

The invention discloses a frog-rice co-culture ecological high-yield breeding-planting method. The method includes: building a spawning pond: arranging rectangular-ambulatory plane trenches in the pond, and arranging food intake areas around the spawning pond and rest land in the middle; releasing seed frogs into the spawning pond according to a male-female ratio of 2:1, and transferring the seedfrogs into an incubation pond for incubation; building a rice field pond: arranging food intake areas around the rice field pond, trenching around the food intake areas, and forming a rice planting area in the middle; releasing tadpoles: releasing the tadpoles into the rice field pond according to density of 500 tadpoles per square meter; planting rice: in the middle of May which is the seedling culture and seeding period in Hubei Province, planting 11-13 thousand plants per mu, and placing shrimp cages in the food intake areas on September in Hubei Province to catch frogs; manually harvesting. The method has the advantages that conditions for co-growth and co-development of frog and rice are improved reasonably, one-field multi-purpose, one-water multi-purpose and one-season multi-harvestdouble high-yield effect is realized, sustainable and sound development of agricultural production is realized, and pure benefit per mu is more than 11000RMB.

Description

technical field [0001] The invention relates to an ecological high-yield planting and breeding method for co-cropping frog and rice. Background technique [0002] Black-spotted frog, also known as frog, is a national second-class protected animal and a master of preying on farmland pests. However, in recent years, pesticides, chemical fertilizers, industrial pollution, and human hunting and eating have led to a sharp decline in the number and become an endangered species. At present, farmers often use various chemical fertilizers 7 times, pesticides 8 times, and herbicides 3 times. The amount of fertilizer per hectare is as high as 400 kilograms, and the utilization rate is decreasing year by year. According to the research of agricultural science experts, my country’s pesticide use is excessive. It is as high as more than 40% in production, which poses a great threat to the safe production of rice and has a great impact on biodiversity. The deposition of organic matter and h...

At present, farmers often use various chemical fertilizers 7 times, pesticides 8 times, and herbicides 3 times. The amount of fertilizer per hectare is as high as 400 kilograms, and the utilization rate is decreasing year by year. According to the research of agricultural science experts, my country’s pesticide use is excessive. It is as high as more than 40% in production, which poses a great threat to the safe production of rice and has a great impact on biodiversity. The deposition of organic matter and heavy metal toxic substances seriously reduces the quality of rice

The existing frog-rice co-cropping ecological high-yield breeding method generally has a low hatching rate of frog eggs, and the yield of frogs is not high enough
