用N~(15)示踪方法研究氨基酸的肥效作用

以Ｎ１５标记的氨基酸为试验材料，证明外源氨基酸分子可以被稻苗直接吸收，并进一步证明氨基酸施肥后稻苗植株健壮，干重增加，是氨基酸分子进入植物体内的结果，这与我们以往所作的氨基酸植物肥效试验结果完全吻合。

A Study on Fertilizer Efficiency of Amino Acids With N15 trace

Using N15-labelled amino acids, this study proved that the amino acid from outside sources can be absorted directly by rice seedling, as indicated by the facts that the rice seedling plants, after amino acid supply, grew vigourously and healthly, and their dry weight increased. All these results coinsided completly with that of the former experimentes about the fertilizer efficiency of amino acids.
