摘要: 设置稻-龟-鳖-鱼综合种养(DGBY)、稻-龟-鱼综合种养(DGY)、水稻单作(DCK)及水稻生态空白种植(DCK0)4个处理,研究不同综合种养模式对稻田病虫草害的防治效果及对水稻产量和品质的影响,以期促进稻渔综合种养生产力的提质增效。结果表明,与DCK0处理相比,DGBY和DGY处理对水稻纹枯病、稻瘟病和稻曲病均有防治效果,其中对纹枯病的防效最好,但防效较DCK处理极显著降低,分别为15.36%和13.19%;DGBY和DGY处理对第5代稻飞虱的防治效果较好,虫量较DCK0处理分别降低56.79%和48.85%,较DCK处理分别降低32.29%和16.95%,对第3代二化螟幼虫的防效次之,虫量较DCK0处理降低39.29%和33.93%,比DCK处理降低15.00%和7.50%。动物放养后50 d,DGBY处理对杂草密度、干质量的防效分别为38.38%、40.15%,DGY处理分别为32.99、35.39%,均与DCK处理无显著差异。除了DCK处理水稻实际产量显著高于DCK0处理外,其他处理间无显著差异。DGBY和DGY处理精米率均较DCK0处理极显著提高,垩白粒率和垩白度均较DCK处理降低,具有改善稻米品质的作用。综上,稻-龟-鳖-鱼、稻-龟-鱼综合种养模式均能在一定程度上减少病虫草的危害,达到稳产增质,减少化肥、农药使用量的目的。

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 DCKtreatment,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.
