摘要： 1978～1980年在三种地力水平下对两个早熟单交种玉米的研究结果表明,麦茬夏玉米干物质积累和对氮、磷、钾吸收的进程,同春播玉米及套种玉米大体上相似。最大的差别是,夏玉米出苗后就进入高温多雨的季节,前期生育快,干物质积累及养分的吸收量都大大超过春玉米和套种玉米,故氮化肥应该早施、重施。

Abstract: Experiments have been carried out with two breeds of single crosshybrid corn planted in the harvested winter wheat fields of three diffe-rent levels of soil fertility in Beijing in 1978 to 1980.The main resultsare as follows:1.The process of dry matter accumulation of summer-sown corn issimilar on t
