摘要
设置常规种植模式和稻虾共作模式,选择10个适宜泰州地区种植的优质粳稻新品种进行比较试验。结果显示,常规种植模式下10个粳稻品种的667 m2群体颖花量和产量都大于稻虾共作模式,且各品种在不同模式下的产量和产量位次表现不尽相同,这与品种特性密切相关;稻虾共作模式下各水稻品种产量均低于常规种植模式,这与两种生产模式不同的田间管理方式有关。
Ten new varieties of high quality japonica rice suitable for planting in Taizhou region were selected for comparative test under conventional planting mode and rice shrimp co cropping mode.The results showed that the average number of effective panicles per 667 m2,total grains per panicle,seed setting rate,1000 grain weight and yield of 10 japonica rice varieties under the conventional planting mode were greater than those under the Rice-Shrimp culture mode,and the total grains per panicle,seed setting rate and yield varied greatly;The yield variation of new varieties of japonica rice under the two models was not significantly different,and the yield level of new varieties of japonica rice under different models was different,which was closely related to the characteristics of varieties.
