[0040] Example 1
[0041] A green rice planting and fish polyculture method, comprising the following process steps:
[0042] (1) Rice field construction:
[0043] a) Rotate the exposed rice field with a rotary tiller first, and level the farmland with a laser leveler;
[0044] b) Build a 0.8m-high cofferdam around the paddy field (widening and strengthening), as if the rice is planted in a basin, excavate a ring-shaped fish breeding ditch along the inner side of the paddy field stalk, the ditch is 1.0m wide and deep 1.5m (a step is designed every 30 meters of ditch length to prevent farmers from drowning);
[0045] c) Dig ditches and build culverts in the middle of the paddy fields, dig a "well" or "day"-shaped field ditch, the width of the field ditch is 0.7m, the depth is 0.6m, the length, width and depth of the culvert are 7×7×1.6m, and the circular fish breeding ditch The area of Hetian fish breeding ditch accounts for about 10% of the total area of rice fields;
