Abstract

Abstract:

Nineteen high-quality new varieties of japonica rice were selected for comparative experiments under the rice-shrimp co-cultivation mode. The results showed that there were varying degrees of differences in the average number of effective panicles per 667 m², total grains per panicle, seed setting rate, thousand grain weight, and yield of 19 japonica rice varieties under the rice-shrimp co-cultivation mode, and the variation in yield components was significant; Among all the tested varieties, the yield of Xiangyuan 99 was higher than that of other varieties, mainly due to the balanced performance of various yield components in the rice-shrimp co-cultivation mode, and the overall excellent indicators of grains per panicle, seed setting rate, and thousand grain weight.

Key words: rice-shrimp co-cultivation, variety comparison, yield performance.
