Abstract
In order to explore the effect of increased application of microbial nutrients on crayfish yield in rice-shrimp co-culture,the study selected five rice-shrimp co-cultivation fields with an area of 1.5hm2,and the exper-iment was divided into five groups,the control group,treatment group A,treatment group B,treatment group C,and treatment group D,with three parallels in each treatment group,and the area of the paddy field in each parallel group was 0.5hm2;1500kg crayfish were randomly placed.The control group of experimental crayfish was fed spe-cial formulated feed for crayfish;treatment A group was fed 90％formulated feed plus 10％microbial nutrients;treatment B group was fed 80％formulated feed plus 20％microbial nutrients;treatment C group was fed 70％for-mulated feed plus 30％microbial nutrients;and treatment D group was fed 60％formulated feed plus 40％microbi-al nutrients.60％formulated feed plus 40％microbial nutrients,and at the end of the experiment the yield values of crayfish were determined.The results showed that the crayfish catch weight of treatment C group was significantly higher than that of control group and other treatment groups(P＜0.05)to treat the lowest crayfish catch weight in group D;The catch weight of crayfish in groups A,B and C showed an increasing trend,indicating that adding 10％to 30％microbial nutrients could increase the weight gain of crayfish,but when adding more than 40％micro-bial nutrients,the catch of crayfish would decrease.关键词
