Abstract：Four treatments were set up,which were rice-turtle-Trionyx-fish comprehensive planting and breeding(DGBY),rice-turtle-fish comprehensive planting and breeding(DGY),rice monoculture(DCK)and rice ecological blank planting(DCK0).The effects of different comprehensive planting and breeding modes on the control of diseases,pests and weeds in paddy fields and rice yield and quality were studied,so as to promote the quality and efficiency of rice-fish comprehensive planting and breeding productivity.The results showed that compared with DCK0 treatment,DGBY and DGY treatments had control effects on rice sheath blight,rice blast and rice false smut.Among them,the control effect on rice sheath blight was the best,but the control effect was significantly lower than that of DCK treatment,which was 15.36%and 13.19%,respectively.The control effects of DGBY and DGY treatments on the 5th generation of rice planthopper were better,and the number of insects decreased by 56.79%and 48.85%compared with DCK0 treatment,and decreased by 32.29%and 16.95%compared with DCK treatment,respectively;Followed by the 3rd generation of Chilo suppressalis,the number of insects decreased by 39.29%and 33.93%compared with DCK0 treatment,and decreased by 15.00%and 7.50%compared with DCK treatment,respectively.At fifty days after the animals were stocked,the control effects of DGBY treatment on weed density and dry weight were 38.38%and 40.15%,respectively,and those of DGY treatment were 32.99%and 35.39%,respectively,which were not significantly different from those of DCK treatment.Except that the actual rice yield of DCK treatment was significantly higher than that of DCK0 treatment,there was no significant difference among other treatments.The milled rice rate of DGBY and DGY treatments were extremely significantly higher than that of DCK0 treatment,and the chalky grain rate and chalkiness were lower than those of DCK treatment,so DGBY and DGY treatments had the effect of improving rice quality.In summary,the rice-turtle-Trionyx-fish and rice-turtle-fish comprehensive planting and breeding models can reduce the harm of diseases,insects pests and weeds to a certain extent,achieve stable yield and improved quality,and reduce the use of chemical fertilizers and pesticides.
