运用生长分析法研究了不同麦玉间套复合群体全生育期干物质积累的动态变化，以及ＬＡＩ、ＣＧＲ、ＮＡＲ与作物生产力间的相关性，指出带回的纳密能力是相对的，通过光合能力的提高来获取高产是可行的。在沿黄灌区现存的麦玉套作模式中Ａ１Ｄ４具有较高的推广价值和增产潜力。
Using the method of growth analysis, the dynamic changes of dry matter accumulation during the whole growth period and the correlation between LAI, CGR, NAR and crop productivity were studied. It was pointed out that the ability to bring back Numisi is relative. Through photosynthesis The ability to improve to obtain high yield is feasible. A1D4 has a high popularization value and yield potential in the existing wheat-jade intercropping pattern along the Yellow River Irrigation District.
