摘　　要：【目的】通过开展稻田鲤鱼不同放养密度对比试验,为制修订相关生产技术规程提供科学依据。【方法】放养体长约6cm的稻田鲤鱼,设置750~8250尾/hm^(2)6个放养密度,观察其对优质稻全年产量的影响,并进行统计分析。【结果】750尾/hm^(2)和2250尾/hm^(2)低密度处理的优质稻全年产量较高,其中2250尾/hm^(2)最高,产量达到8230.5 kg/hm^(2)。【结论】2250尾/hm^(2)的放养密度既能充分利用稻田天然饵料资源,又能保证优质稻获得高产。在本试验条件下,以放养密度2250尾/hm^(2)为最佳。【Objective】The comparative test of different stocking densities of carp in paddy field was carried out to provide scientific basis for the revision of relevant production technical regulations.【Method】The effects of six stocking densities of 750/hm^(2)~8250/hm^(2) on the annual yield of high-quality rice were observed and statistically analyzed.【Result】The annual yield of high-quality rice in the low-density treatments of 750/hm^(2) and 2250/hm^(2) was higher,of which 2250/hm^(2) was the highest,and the yield reached 8230.5 kg/hm^(2).【Conclusion】The stocking density of 2250/hm^(2) can not only make full use of the natural bait resources in the paddy field,but also ensure the high yield of high-quality rice.Under the conditions of this experiment,the stocking density of 2250/hm^(2) was the best.
