| 摘 要： | 大田条件下，选用2个有代表性的强、弱筋型冬小麦品种，研究追肥时期对小麦淀粉糊化特性的影响。结果表明：除糊化时间外，其他性状变异系数均大于10％，而且两种筋型品种之间淀粉糊化特性的变异幅度有较大差异。强筋型品种豫麦34号的淀粉糊化特性值均高于弱筋型品种豫麦50号。随追肥时期变化，两种筋型品种的变化规律不同，且均以拔节期追肥表现较优，因此，拔节期是淀粉糊化特性的较佳施肥时期。

| Abstract: | In the field,two cultivars including strong and weak gluten winter wheat varieties were cultivated,and the effects of topdressing stage on starch paste characters were analyzed. The results indicated that,except the paste time,the variation coefficients of the other characters were more than 10%,and the variation extents of two kinds of cultivars were different. The character values of strong gluten variety Yumai 34 were bigger than that of weak gluten variety Yumai 50.With the variation of topdressing stage,two kinds of cultivars had different changing rules,and the character values in elongation stage were better,so the elongation stage is the best topdressing stage. |
