摘要
在不同肥力水平土壤条件下 ,采用肥料田间试验和测试分析方法 ,对 10 0个小麦品种(系 )的产量、蛋白质含量和氮肥效率进行了系统筛选研究。筛选出了几个产量、蛋白质含量和氮肥效率均较高或产量、氮肥效率较高的品种 ;同时通过相关分析 ,研究得出了筛选指标 ,即在中等肥力土壤条件下可采用蛋白质产量作指标筛选 。
Through field experiment and testing analysis of the samples, 100 wheat varieties with different yield, protein content and nitrogen fertilizer efficiency were studied and selecred systematically under the different fertility of soil conditions. Several wheat varieties with higher yield, higher protein content and higher nitrogen fertilizer efficiency or with higher yield and higher nitrogen fertilizer efficiency were selected. At the same time, the indices of selection were obtained by correlation analysis. The result indicated that protein yield could be selected as the selection target under medium fertility of soil condition, and both protein yield and protein content could be selected as a selection target under high fertility of soil condition.
