本項目的研究內容主要包括變頻調速裝置在管灌、微噴以及大棚滴灌中的節能效果、變頻調速裝置對微噴和大棚滴灌均勻度的影響以及變頻調速裝置在管灌中進行「恆量變壓」變頻運行試驗等,同時,對微噴頭與中smm低壓插入式滴灌帶的灌溉均勻度隨壓力變化情況進行一r試驗研究。Plastic equipment for water saving irrigation - drip tape with labyrinth on one side
塑料節水灌溉器材單翼迷宮式滴灌帶With the in - built drip irrigation belt and thin wall chip irrigation belt taken as examples, the flow rate distribution and hydraulic losses of drippers along capillary tubes at different inlet pressures were measured under the conditions of horizontal slope and slope gradients of 0. 5 % and 1 %, then the uniformity of capillary tubes was calculated at different slope gradients and pressures in consideration of the manufacture deviation of drippers
摘要以內鑲式滴灌帶和薄壁滴灌帶為研究對象,測定了平坡、 0 . 5 %坡度和1 %坡度時,不同入口壓力下滴頭沿毛管的流量分佈和水力損失,並結合滴頭的製造偏差,計算得出不同坡度和壓力條件下滴灌毛管的均勻度。Abstract : problems caused in designing and management including configuring regulating devices, deciding spaces of the last pipelines, and working - out irrigation scheme in reason using drip irrigation in green houses and in covered lands are raising in recent years, theose not only affect benefits but also result in failing of projects
文摘:近幾年來溫室、大棚種植蔬菜採用滴灌技術的越來越多,但有些工程無論設計上、管理上都存在一些問題,包括調壓設備的合理配置,按土壤、作物、灌水器及滴灌總水量合理確定毛管(或滴灌帶)的間距,以及按大棚蔬菜的耗水特性合理確定灌溉制度等,上述各項確定的不合理,不但直接影響效益,嚴重時可導致工程失敗,值得重視。A new type paving equipment for drip irrigation belt
