摘　　要：调查行向对不同穗型水稻群体光分布的影响,结果表明:无论直立穗型还是弯曲穗型,均是南北行向较东西行向多受光;无论南北行向还是东西行向,直立穗型群体内各高度处光照强度大于弯曲穗型群体;直立穗型品种和弯曲穗型品种均适于南北行向种植。Studied the effection of different row direction on population light distribution in different panicle types, it showed that, the population could receive more light in SN direction than that in WE direction of both erect panicle and curve panicle type rice. No matter S-N or WE direction, solar intensity at different height of erect panicle was bigger than that of curve panicle type rice. The reflection intensity above rice canopies of erect panicle was weaker than that of curve panicle type rice. Both erect panicle and curve panicle type rice were suit planted in S-N direction.
