Japonica Rice Yield under Rice-Shrimp Culture and Conventional Cropping Patterns Comparative Test
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.
