1992～1996年,我们对小麦500kg生育特性及优化调控技术进行了系统研究,并在大面积生产应用。结果表明,小麦亩产500kg,可以通过多种途径实现。但从年际间、田块间重演性分析,稳定500kg旨在以一定的播期范围和不同的土、肥、水等生产条件为基础,以调整合理的群体起点为开端,以优化群体质量为主攻方向,以 From 1992 to 1996, we conducted a systematic research on the characteristics of 500kg wheat and the optimal regulation and control technology, and applied it in large-scale production. The results show that wheat yield 500kg per mu can be achieved through a variety of ways. However, from year to year, inter-field plots of reanalysis, stable 500kg aiming to a certain sowing date range and different soil, fertilizer, water and other production conditions, to adjust the starting point for a reasonable group to optimize the quality of the group As the main direction to
