(Rice grows in water and shrimp is downstream of rice) is a vivid portrayal of the ecological farming model of "shrimp-rice cooperation".

"Rice and shrimp * * *" ecological culture mode refers to the green and efficient comprehensive culture mode of crayfish and mid-season rice rotation in southern China. Mainly planting rice, and cultivating crayfish after harvesting in rice fields. The technical points are as follows: release parent shrimps before mid-season rice harvest from August to September every year, or raise seedlings after harvest, harvest shrimps from March to August the following year, and transplant them in the whole field in late May or early June the following year. First of all, we should choose high-quality rice fields without pollution or less pollution, which is convenient for drainage and transportation.
