研究结果表明,行向对不同穗型水稻品种的产量影响不显著。东西行向配置可极显著地增加一次枝梗粒数,直立穗型品种沈农265采用东西行向配置对增加一次枝梗粒数更为有利。每穗粒数与之趋势一致。不同穗型品种间叶重、茎重、成穗率、千粒重、经济系数等差异显著,但不同行向间差异不显著。
The results showed that the row direction had no significant effect on the yield of rice varieties with different panicle types. The allocation of east-west rows can significantly increase the number of primary branchlets, and the erect panicle variety Shennong 265 is more advantageous to increase the number of primary branchlets with east-west row configuration. The number of grains per spike is consistent with the trend. The differences of leaf weight, stem weight, spike rate, 1000-grain weight and economic coefficient of different panicle cultivars were significant, but the differences between different rows were not significant.
