摘要:

选择19个优质粳稻新品种进行稻虾共作种植模式下的比较试验。结果显示,稻虾共作种植模式下19个粳稻品种的667 m2有效穗数、每穗总粒数、结实率、千粒重和产量均存在不同程度的差异,产量构成因素间的变幅均较大;所有参试品种中,香缘99的产量高于其他品种,主要得益于该品种在稻虾共作模式中的各项产量构成因素表现较为均衡,每穗粒数、结实率和千粒重指标整体比较优秀。

关键词: 稻虾共作, 品种比较, 产量表现

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.
