摘  要:
田间配置方式对不同穗型水稻生理特性影响的结果表明 ,品种间叶绿素含量存在较大差异 ,辽粳326的上2叶叶绿素含量显著高于奥羽316;品种、行距对可溶性糖含量的影响达到极显著水平 ,行向之间、行向与品种互作对可溶性糖含量的影响达到显著水平 ,辽粳326比奥羽316高 ,40cm行距高于30cm行距 ,南北行向高于东西行向。行距对群体光合速率影响较大 ,扩大行距对提高群体中午时的群体光合速率有利。

摘  要:
The effect of field arrangement on physiological characteristics of different panicle type rice was analyzed.The results showed that there were differences in chlorophyll contents between two rice varieties.Liaojing326had higher value than Okuba316in the top two leaves.Varieties and row spacing had significant effects on soluble sugar contents,while row direction and the interacˉtion of row direction and varieties also had evident effects.For soluble sugar contents,Liaojing326was higher than Okuba316,40cm row spacing was higher than30cm row spacing,and N-S direction was higher than E-W direction.The row spacing had a big efˉfect on photosynthetic rate.It was beneficial to improve photosynthetic rate at noon through expanding row spacing.
