Our work reported here are aiming at improving nitrogen and water use efficiency in wheat/maize, faba bean/maize, pea/maize and soybean/maize intercropping through field experiment.The main results obtained were as the following:(1) Land equivalent ratio was greater than 1.0 for faba bean (Viciafaba L.)/maize (Zea mays L.) intercropping regardless of nitrogen fertilizer application or not. Based on grain yields production, LER of pea (Pisum sativum L.)/maize intercropping was over 1.0 in spite of nitrogen fertilizer application, while LER was higher than 1.0 only when nitrogen fertilizer was applied based on biomass production. However, LER in soybean (Glycine max L.)/maize intercropping was smaller than 1.0 both nitrogen applicationa and no nitrogen application. In wheat Triticum aestivum L.

In the seedlings time, the content of chlorophyll decreased by the deficiency of B, but the content of chlorophyll in the high efficiency cultivar decreased slowly than that of the low efficiency cultivar. This suggested that the leaves of the high efficiency cultivar can capture more light energy and the photosynthetic rate of the high efficiency cultivar decreased slowly. In the bolting time and blooming time, after two weeks of B deficiency treatment, the content of chlorophyll in the top leaves of the high efficiency cultivar decreased, and in the late time, the content of chlorophyll decreased slowly. But, the content of chlorophyll in the bellow leaves of the two cultivars had little changes. The reason may be that B in the high efficiency cultivar distributed to the propagative organ in the late growth, and the leaves were short of B.

苗期，缺硼导致甘蓝型油菜色素含量降低，且高效品种色素含量下降的幅度小于低效品种，表明营养生长阶段，同等程度的缺硼条件下，高效品种叶片对光能的收集能力以及光合速率下降的程度相对较小；苔期和花期，在两周的缺硼处理后，高效品种上部叶色素含量依然呈下降趋势，但随着生育期的推移，其下降幅度减小；而高效品种下部叶和低效品种叶片含量变化不大，可能是甘蓝型油菜进入生殖生长阶段后，高效品种将硼更多地分配到繁殖器官，而其叶片却承受了相对较大的缺硼胁迫。
