摘　　要：目前稻虾模式发展规模越来越大,因养殖水平参差不齐,过量投喂饲料现象严重,从而增加了养殖水体富营养化风险。试验采用微生物营养料替代部分饲料投喂,结果显示添加微生物营养料后,小龙虾产量折算每公顷平均增产139.5 kg,且能提高养殖水体pH、增加水体溶氧量0.15 mg/L、降低氨氮含量0.09 mg/L、降低亚硝酸盐含量0.006 mg/L,但增加了总磷含量,平均增加量为0.17 mg/L。表明微生物营养料可稳定维持养殖水体pH在弱碱性环境,增加了水体溶氧含量和降低水体中氨氮、亚硝酸盐类物质含量,为小龙虾健康生长创造了适宜的水体环境,同时提高了小龙虾代谢强度,促进了小龙虾摄食量增大,加快了其生长速度。At present,the scale of the development of the shrimp and rice farming is getting larger and larger.Due to the uneven level of aquaculture,excessive feed feeding is a serious phenomenon,which increases the risk of eutrophication of aquaculture water.In this experiment,microbial nutrient was used to replace part of the feed.The results showed that after adding microbial nutrient,the crayfish production was reduced by an average of 139.5 kg per hectare,and the pH value of the aquaculture water was increased,and the dissolved oxygen content of the water increased by 0.15 mg/L.The content of ammonia nitrogen and nitrite decreased by 0.09 mg/L and 0.006 mg/L,respectively.But the total phosphorus content was increased,and the average increase was 0.17 mg/L.It indicates that the microbial nutrient can stably maintain the pH value of the aquaculture water in a weak alkaline environment,increase the dissolved oxygen content of the water body and reduce the content of ammonia nitrogen and nitrite substances in the water body,and create a suitable water environment for the healthy growth of crayfish,and increase the metabolic intensity of crayfish,promote the increase in food intake of crayfish and accelerates the growth.
