| 摘 要： | 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。

| Abstract: | The relationship between crop productivity and the characteristics of thewheat/corn intercropping systems are discussed in this paper. The NAR is correlated positivelywith the yield in different intercropping systems, however the relationship between LAI and theyield of wheat/corn systems are negative in A1D4、A2D2、 A2D3 、 A2D4 systems. Compared withall of the systems, it shows that A1D3 is the moderate system which can be extentioned in GansuYellow River irrigation district. The high yield of crop production can be getten by improving thephoto syrathetic. |
