Novel crayfish and rice rotation breeding and planting method

The invention discloses a novel crayfish and rice rotation breeding and planting method. The method comprises the following steps: a crayfish fry pond and a breeding pond are built separately in the area ratio being 1:(4-10). Seed crayfish are put into the crayfish fry pond, and after crayfish fries are bred, the crayfish fries in the consistent specification (60-70 crayfish per jin) are caught and then put into the breeding pond in the density of 5,000-8,000 crayfish per mu. After the crayfish fries in the breeding pond grow to be 20 g or above, the crayfish fries are caught in a catch rotation manner that only large crayfish fries are caught, then crayfish fries are caught from the crayfish fry pond and put into the breeding pond after the large crayfish fries in the breeding pond are caught, and accordingly, the breeding density of the breeding pond keeps unchanged. After all the crayfish fries are almost caught, rice is planted in the breeding pond in the traditional planting density. The breeding density of crayfish can be well controlled, burst of diseases caused by high breeding density of the crayfish is avoided, and finally, high-quality commodity crayfish are obtained. The utilization rate of land is increased in the manner of catching and stocking rotation, and better benefits are obtained.
