梯级水平畦灌机理研究及其应用
|
摘要
针对水平畦灌在长畦和透水性较强情况下,灌水均匀度和灌水利用率降低的问题,同时为减轻土地平整工作量,提出"梯级水平畦灌"理论,建立了相应的数学模型,并将计算结果和田间试验结果与现有水平畦灌理论进行比较,表明该模型适用范围广,节水、省工并提高灌水质量。
In order to solve the low irrigation uniformity and irrigation utilization efficiency of horizontal border irrigation and reduce land leveling work under the condition of long close-end border and high water permeability,the horizontal border irrigation theory was proposed,and the corresponding mathematic model was established in this paper. Then the calculated results and field test results were compared with the existing horizontal border irrigation theory. The results show that this model has the merits of wide application and is beneficial for watersaving,labor-saving and increasing irrigating quality.
