摘要
对不同优质小麦品种不同播期的产量结构分析结果表明:河北-8901的各种产量结构表现出最为稳定的变化规律,即不同的播期处理对最后产量的影响度相对较小;郑麦-9405和郑麦-9023的产量结构在不同的播期表现出较大的波动。
With the analysis of yields formation of high quality wheat： in different seeding time, the results indicate the variety rule of Hebei - 8901 is the steadiest, which is to say that different seeding time has no much effect on its last yield. But the variety rules of Zhengmai -9405 and Zhengmai -9023 show remarkable fluctuation.
