By stocking different numbers of sheldrakes （0, 75, 150, 225, 300, 375 /hm2） in the rice and turtle co-cropping field, we compared and analyzed the effects of different numbers of sheldrakes on the occurrence of weeds, yield and quality of rice. The results showed that with the increase of the stocking numbers of sheldrakes, the number of weeds and the total dry matter in each growth period of the rice-turtle co-cropping field gradually decreased, and the treatment with a stocking number of 375 /hm2 had the best weed control effects. The yield of rice increased first and then decreased with the increase in the number of sheldrakes sacked, the treatment with the number of stocking was 225 /hm2 was the highest. At the same time, this treatment also improved the eating quality of rice. Based on the performance of weed control, rice yield and rice quality, the number of sheldrake stocked in the rice-turtle co-cropping field should be 225 /hm2.
Key words： rice; sheldrake; rice and turtle co-cropping field; weed control; yield; quality
