Root function in uptake of nutrients and the effect of soil water on the transfer and distribution of NO3−-N in arable soil were studied using summer maize (Zea mays L. var. Shandan 9) as a testing crop. Results showed that root growth and water supply had a significant effect on NO3−-N transfer and made NO3−-N distributed evenly from bulk soil to rhizosphere soil. Under a natural condition with irrigation, the difference of NO3−-N concentration at different distance points from a maize plant was smaller, while obvious difference of NO3−-N...

在营养素的举起和 NO3 的转移和分发上的土壤水的效果的根功能 ? 在耕地土壤的 -N 用夏天玉米被学习(Zea mays L。var。Shandan 9 ) 作为严峻的庄稼。结果证明根生长和给水在 NO3 上有重要效果 ?-N 转移和做的 NO3 ? 从体积土壤均匀地散布到根围土壤的 -N。在有灌溉的一个自然条件下面， NO3 的差别 ? 在从玉米植物的不同距离点的 -N 集中更小，当时 NO3 的明显的差别 ? 没有灌溉， -N 集中在有限的根生长空间的条件下面被观察。根生长空间是否被限制，土壤 NO3 的内容 ?-N 从植物从 10 ～ 0 厘米逐渐地减少了，对根相反专心于区域土壤。当根成年的空间是有限的时， NO3 的变化 ? 在从植物的不同...
