文摘:本文根據水量平衡原理，提出了利用大田畦灌灌水資料推求土壤入滲參數的方法，在此基礎上，又提出了利用波涌灌水流推進和消退資料確定間歇入滲減滲率系數的方法。The calculation example shows that the method is simple and effective
該研究成果為波涌畦灌技術要素設計和灌水質量評價奠定了基礎。Strip check space varies with plot slope, soil fertility and irrigation
條畦寬度隨地塊坡度、土壤肥力和灌溉而變化。Experiment on cucumber in greenhouse showed that, compared with traditional flooding and fertilization techniques, technology of integrated management of water and fertilizer on cucumber in greenhouse could save water and fertilizer, reduce relative humidity of greenhouse and heat loss, improve physical and chemical property of soil, it could increase yield and improve quality of cucumber, raise income and reduce cost
摘要通過水肥一體化技術與傳統畦灌沖施肥技術對比試驗分析，明確了大棚黃瓜水肥一體化技術效應主要是節水、節肥、節藥、降低棚內空氣濕度和保持棚內氣溫，有助於土壤理化性狀的改善，取得提高產量和品質、減少投資、增加收入等效應。Analysis of water flow performance and irrigation efficiency of boder irragation under straw mulch
秸稈覆蓋畦田灌溉水流特性及灌水質量分析Due to the underdevelopment of economy, traditional surface irrigation such as border and furrow irrigation is still taken as the dominant way in farmland irrigation, which leads to the great waste of water resources. therefore, how to apply a new theory to study and improve surface irrigation technique in order to increase water use efficiency and water productivity in farmland, has become a key project in water - saving research of agriculture today
然而，由於經濟欠發達，我國農田灌溉仍以傳統的畦、溝地面灌溉技術為主，水資源浪費現象還比較嚴重，因此，如何運用新的理論研究和改進地面灌水技術，提高農田水分利用效率和水的生產效率，已成為當今我國農業節水研究的重點課題。In addition, this paper selects the water traveling wave model of the surface irrigation, and realizes the modeling of the water movement, according to the water movement characteristics of surface irrigation. furthermore, the optimization model for irrigation effects is used to produce the calculation pattern in which the water movement model is combined with optimization of technical parameters of irrigation. therefore, it is realized that the optimum unit discharge is calc ulated under the condition of definite length and slope of border check and the optimum length of border check is calculated under the condition of definite unit discharge and slope
與此同時，在分析項目區耕作條件下灌溉水流運動特點的基礎上，選擇地面灌溉水流運動波模型，實現了地面灌溉水流運動的數值模擬，並利用灌溉效果優化模型，構造了地面灌溉水流運動模擬與灌水技術參數優化相結合的計算模式，實現了定畦長、定坡降條件下的優化單寬流量求解和定單寬流量、定坡降條件下優化畦長的求解，為變灌水條件下優化灌水技術參數的確定提供了強有力的工具。分享友人
