Effect of Carp Stocking Density on Annual Yield of High Quality Rice in Mountainous Paddy Field
[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/hm2~8250/hm2 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/hm2 and 2250/hm2 was higher,of which 2250/hm2 was the highest,and the yield reached 8230.5 kg/hm2.[Conclusion]The stocking density of 2250/hm2 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/hm2 was the best.
