    摘要:

    為探索交替隔溝灌溉條件下玉米優(yōu)化水氮供給模式，通過遮雨棚內(nèi)微區(qū)試驗，研究了溝灌方式、灌水量和施氮量對玉米群體水氮利用的影響。結(jié)果表明：交替隔溝灌溉中水低氮處理的籽粒產(chǎn)量最高，是交替隔溝灌溉高水高氮處理的1.06倍。在相同水分和氮肥條件下，交替隔溝灌溉的籽粒產(chǎn)量分別是常規(guī)溝灌和固定隔溝灌溉的1.05、1.16倍。各因素對全氮累積總量的影響從大到小依次為：溝灌方式、施氮量、灌水量；灌水量對全氮累積總量影響顯著。

    Abstract:

    The object is to explore an optimal supply model of water and nitrogen on maize under alternative furrow irrigation, the micro-field experiments of rain-shield was conducted about furrow irrigation mode, nitrogen rate and irrigation amount. Results showed that the maize yield of alternative furrow irrigation (AFI), middle water and low nitrogen rate had the maximum grain yield, which was 1.06 times of AFI, high water and high nitrogen rate. Under the same water and nitrogen, the yield of AFI was 1.05 times of normal furrow irrigation (NFI), and 1.16 times of fixed furrow irrigation (FFI). Total nitrogen accumulation (TNA) of AFI was the most, NFI was the second, and FFI was the minimum. The order of effect on TNA was furrow irrigation mode, nitrogen rate and irrigation amount, the influences of irrigation amount on TNA reached significant level.
