根據一維土柱近似的濕潤輪廓線初步選定了工程設計參數。在地下滴灌灌水器出流量較小情況下,埋深應淺,孔距應選擇和毛管間距相等或接近;出流量大時,埋深可深,孔距大於毛管間距仍可獲得較均勻的土壤水分分佈。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。Td - 200 text panel monitor and applicable for realizing the revise the times parameters of paint - dropping, balance, remaining time and so on
