关于粒用高粱的产量与施肥的关系,已经有过一些报道,其中大部分报道都说明氮肥对高粱生长与籽粒产量是有效的。Genfer、Rai和Mirhadi等人观察到氮素是高粱增产的唯一因素。Miller、Cambell、Tweedy和其他一些研究工作者发现,增施氮肥不仅能提高籽粒产量,而且能提高籽粒的蛋白质含量。但是,由于他们的试验大都是在田间条件下进行的,因此要想找出一个获得最高产量和蛋白质含量的最佳 There have been some reports about the relationship between grain sorghum yield and fertilization. Most of the reports show that nitrogen fertilizer is effective on sorghum growth and grain yield. Genfer, Rai and Mirhadi et al. Observed that nitrogen was the only factor that increased sorghum yield. Miller, Cambell, Tweedy and some other researchers found that increasing N fertilizer not only increased grain yield, but also increased grain protein content. However, since most of their experiments are conducted under field conditions, it is important to find the best one to achieve the highest yield and protein content
