摘要： 采用水培和盆栽试验，在低磷和高磷两个供磷水平下，以6个不同玉米基因型种子为材料，对玉米基因型生物性状和磷效率进行比较，结果表明：在水培试验下，玉米基因型的相对主根长和相对根冠比均比盆栽试验低，相对干重和磷效率均比盆栽试验高，方差分析表明，不同试验方法间相对主根长、相对根冠比、相对干重和磷效率均达显著差异。

Abstract: Under low and high P application, 6 Maize genotypes were selected to compare the biological characteristics and P efficiency by hydroponic culture and pot experiment in maize genotypes. The main results were summarized as follows: The relative length of chief root (RLC) and relative root-shoot rati(RRR) were low in hydroponic culture than pot experiment , but relative dry weight(RW) and P efficiency were high. The variance analysis indicated that the difference of length of chief root, root-shoot ratio, relative dry weight and P efficiency was significance between hydroponic culture and pot experiment.
