本文以不同品质类型的小麦品种为试材,分析比较不同品种的产量潜力及其产量动态变化规律。结果表明:中筋品种克97-831产量显著高于强筋和弱筋类型,分别较克旱19号、新克旱号、克90-99、龙麦26高出21.6%,20.66%,18.7%,30.5%.产量构成因子中以不同品种产量构成因子对产量的作用关系不同。绿色旗叶面积始花期达到顶峰后,下降陡度小,灌浆速率大,且持续时间长,利于有效同化产物的转化。收获指数对籽粒增重为正效应。
In this paper, wheat varieties of different quality types were used as materials to analyze and compare the yield potential of different varieties and their dynamic changes in yield. The results showed that the yield of middle gluten cultivar Ke 97-831 was significantly higher than that of strong gluten and weak gluten, which were 21.6%, 20.66% and 18.7% higher than that of Kehan 19, Xin Ke Han, Ke 90-99 and Longmai 26 respectively. , 30.5% .Production composition factors in different varieties of yield factors on the role of different relations. Green flag leaf area after the beginning of flowering peak, the decline of steepness, filling rate, and long duration, which is conducive to the conversion of effective assimilation products. Harvest index has a positive effect on grain weight gain.
