不同播期的麦田均可实现亩产500kg高产,但要求不同的农艺组合措施与之配合,从而形成小麦高产的多途径。由于播期的不同,造成不同麦田前期苗情差异甚大,通过运用各自相应的配套措施,在群体建成阶段进行调控,把途径间的光合生产进程各项指标调整到同一水平,即具有无效分蘖衰减迅速,无效消耗少;开花期叶面积适宜分布合理,后期净光生产率高;干物质积累前轻后重等共同特点,可殊途同归,共创高产。
Different sowing date wheat fields can be achieved 500kg per mu yield, but require different agronomic combination of measures with which to form a multi-channel high-yield wheat. Due to the different sowing dates, the differences of seedling conditions in different wheat fields in the early stage are very different. By using their corresponding supporting measures, the control of photosynthetic production processes in the path is adjusted to the same level, that is, the tiller attenuation Rapid and inefficient consumption; suitable leaf area at the flowering stage is reasonable and the post-production net light production rate is high; the dry-matter accumulation before and after the light weight and other common features, can be the same way to create high yield.
