摘 要 ：实验着重研究分根条件下常规灌溉、交替灌溉和固定灌溉玉米苗期根际硝态氮的分布, 研究结果表明不同灌水方式下,玉米根际硝态氮的分布不同.在这3种灌水方式的湿润区,NO-3-N的累积趋势为交替灌水＞固定灌水＞常规灌水.

Abstract:This paper study the distribution of NO~-_3-N in the rhizosphere soil of maize under controlled root divided normal irrigation,controlled root divided alternate irrigation and fixed irrigation.The results showed that the distribution of NO~-_3-N in the rh
