用缺锌的纷砂壤质褐土为盆栽试验基质进行大豆氮锌营养研究。结果表明,施锌对大豆有增产作用;氮锌配施,效果更显著。植株锌浓度和吸锌量与施锌量呈正相关,锌的分布是叶>籽粒>荚皮>茎。配施锌肥后有助于叶部锌向籽粒转移。地上部氮(浓度和吸氮量均与施销量呈显著线性正相关,配施锌肥后籽粒氮的份额比单施氮处理高18.5一27.2％,主要是锌促进了叶部蛋白质向籽粒转移的结果。大豆磷锌拮抗现象不明显,而是锌有助于叶部磷向籽粒转移,比对照高出近一倍。
Zinc - deficient sandy loamy cinnamon soil was used as pot experiment medium to study the nitrogen and zinc nutrition of soybean. The results showed that applying zinc had an increased yield on soybean; the combination of nitrogen and zinc was more effective. Plant zinc concentration and zinc absorption and zinc content was positively correlated, the distribution of zinc leaf> grain> Pod> stems. With zinc fertilizer to help foliar zinc transfer to the grain. Above-ground nitrogen (both concentration and N uptake were significantly and positively correlated with the sales volume. The proportion of nitrogen in the grain with zinc fertilization was 18.5-27.2% higher than that in the single nitrogen treatment, mainly zinc promoted the leaf protein transfer to the grain Of the results of soybean phosphorus and zinc antagonism is not obvious, but zinc helps leaf phosphorus transfer to the grain, nearly double the control.
