In the adjustment of planting structure in 1985, according to the fixed-point experimental research and sampling survey conducted by the agricultural sector for six consecutive years, the Chaohu region demonstrated the promotion of rape-watermelon-late rice, rapeseed - early rice - tomato, spring potato - early rice - double late, early rice - cabbage - garlic, tomato - late rice, early rice - water chestnuts, mat grass - late rice, early rice - vegetables, Class, spring corn - late rice and other 10 kinds of rice, crop rotation mode (hereinafter referred to as the rotation of rice).
