| 摘 要： | 为了给春小麦高产栽培提供准确的参考指标，在不同栽培条件下，对呼和浩特、巴盟河套两地灌区春小麦生育期间叶面积指数发展动态进行了系统的研究。结果表明，春小麦全生育期叶面积指数呈单峰曲线变化，峰值在孕穗期，高产麦田最大叶面积指数为6．5～7．5，且因密度、施肥量的不同表现出一定的差异。两地区春小麦不同生育时期适宜的叶面积指数发展变化基本一致，只有叶面积指数适宜，才能达到经济产量最高。

| Abstract: | The dynamic change of spring wheat LAI was studed under different cultivation conditions during growth in irrigation of Huhhot and Bameng. The results showed that LAI of spring wheat changed as a curve and its peak emerged at booting stage. The max LAI was 6. 5 - 7. 5 in the high-yield field, and there were some differences among different densities and fertilizations. The change and development of optimum LAI in the same stage were similar in both regions. The highest economic yield was got as long as LAI was optimum. |
