小麦稳叶控株增穗高产新途径的理论与实践

Theory and Practice of a New Way for Getting High-yield of Wheat-Stabilizing LAI and Controlling Plant Type and Increasing Number of Ears

摘要:

在分析以往小麦高产途径的基础上,提出一条稳住叶面积系数、控制株型增穗数的小麦高产新途径。实践证明,该途径有助于促进源库流在高水平上协调与平衡,且有助于收获指数的提高,故成为现阶段实现小麦单产稳定通过9t/hm²,进而获取更高产量的较好途径。

Abstract:

After previous ways of getting high-yield wheat being reviewed, a new way was put forward in the paper, i. e. stabilizing LAI, controlling plant type and increasing number of ears. It was proved that the coordination and balance of source-sink-translocation on high-yield level could be achieved and harvest index increased by adopting this way. We got 9t/hm² at present and may get higher yield in the future.
