Detailed Explanation of Rice-Fish-Loach Ecological Agriculture Engineering Technology
1. Environmental conditions of the production area: a good ecological environment, far from pollution sources, good air; high, thick and compact paddy field ridges, relatively clayey soil, relatively high soil fertility, and paddy fields with sustainable development capacity; good irrigation and drainage conditions, relatively sufficient water sources, and fresh water quality. 2. Paddy field engineering facilities: dig a ring-shaped ditch around the paddy field, with a ditch width of 1 m and a depth of 0.5 m; surround the field ridges with anti-escape plastic sheeting (40-50 cm above ground, buried 20-30 cm underground); install double-layer anti-escape blocking nets at the water inlet and outlet. 3. Rice, river crab,
