    摘要:

    以楊凌區(qū)進(jìn)行的畦灌大田試驗(yàn)為基礎(chǔ),，采用WinSRFR軟件對(duì)各試驗(yàn)點(diǎn)的灌水質(zhì)量進(jìn)行了模擬，并分析了畦長(zhǎng),、田面坡度,、入畦單寬流量和改口成數(shù)對(duì)灌水效率Ea,、灌水均勻度Ed和儲(chǔ)水效率Es的影響；在此基礎(chǔ)上,，結(jié)合均勻試驗(yàn)設(shè)計(jì)與多元回歸分析的方法,，構(gòu)建了包含灌水效率Ea、灌水均勻度Ed和儲(chǔ)水效率Es在內(nèi)的單目標(biāo)優(yōu)化模型,，以入畦單寬流量和灌水時(shí)間為變量,，采用遺傳算法對(duì)模型進(jìn)行求解，提出了試驗(yàn)點(diǎn)不同計(jì)劃灌水深度條件下畦灌灌水技術(shù)要素的優(yōu)化組合,，結(jié)果表明其可獲得高的灌水質(zhì)量,，達(dá)到常規(guī)畦灌節(jié)水的目的。

    Abstract:

    Based on the field experiments carried out in Yangling, the values of irrigation performance were simulated by the WinSRFR software, and the influence of border length, field slope, unit discharge and cutoff time on irrigation application efficiency, distribution uniformity and storage efficiency were analyzed. On this basis, combined with uniform design and multiple regression analysis,，a single-objective optimization model was established including irrigation application efficiency, distribution uniformity and storage efficiency, and taking unit discharge and cutoff time as variables. The model was solved by genetic algorithms, the optimized combination of irrigation technique element under different theories of water requirement were proposed in Wangshang Village, the results show that it can realize a high irrigation performance and water saving for border irrigation through a proper selection of unit discharge and cutoff time.
