摘要
对河南省具有超高产潜力的五个冬小麦品种进行了冠层结构与产量的研究。结果表明:不同品种的冠层结构、产量之间存在显著差异。适当加大穗下节间长度,提高株高构成指数,降低叶片与茎杆角度及叶片披垂度,延迟冠层绿色叶面积的下降速度,有利于提高产量,并对今后如何改善品种的冠层结构与光合性能、提高品种产量等问题进行了探讨。
The relation of crest layer structure and yield of 5 superhigh yielding wheat were studied. The results are as follows: The remarkable difference on yield and crest layer structure existed between different superhigh yielding wheat. It is helpful to increase yield that increasing the Length of first internode from the top and Plant height component index, decreasing angle of leaf growing, delaying the speed of decline of the area of leaf. And, it had also discussed the problems of how to improve the crest layer structure,photosynthesis capacity, and to increase yield of different superhigh yielding.
