    滴灌系統的灌均勻度受眾多因素的影響,本文通過徑、滴頭間距、長、灌器的類型和灌器的量系數不同的情況下,灌均勻度隨壓力頭變化模擬結果顯示,壓力頭對灌均勻度影響非常小。
  2. When soil antecedent condition is dry and the initial rainfall intensity is high, peak surface runoff also considerably lag behind that of rainfall, because of the formation of temporary relative impermeable top layer ; b ) surface runoff is controlled primarily by infiltration - excess runoff mechanism under unsaturated condition ; the major fraction of surface runoff are dominated by saturated infiltration - excess runoff response, only a small fraction by return flow mechanism when soil is saturated ; c ) subsurface flow is dominated by saturated runoff mechanism, and the duration of subsurface post the rainfall end is dependent upon rather the soil properties than the rainfall characteristics ; d ) subsurface flow intensity in cultivated soil layer ( 0 ~ 20cm ) is high up to 35mm / h when rainfall intensity is up to 120mm / h, indicating the existing of macropores and pipe flow in cultivated layer

    2 )耕作制下紫色土的產主要機制是: 1 )當雨前土壤含量未達到飽和狀態時,表面產起始時間有明顯滯后現象,這與紫色土的快吸性和較多非孔隙密切相關;當雨前土壤較乾燥,降雨初期雨強較大時,易形成臨時相對不透表層,表面產峰也有明顯滯后現象。 2 )表面徑的產方式主要是超滲產,當土壤達到飽和狀態后,有四川大學博士學位論文小部分回歸發生,但主要是飽和超滲產發生,因為紫色土的相對不透層和其它透障礙層不明顯。 3 )壤中主要是飽和產,與降雨過程有明顯的滯后,而且雨停后的壤中歷時與降雨特徵無關。
  3. ( 4 ) through the hydraulic property experiment of micro - hole lateral pipes of simple sdi in air, it was found that the average pressure of 60 mitre length lateral pipes was at the position of per 40o / o ~ ~ ~ 50 % of the effectual pipe length from the fist micro - hole, major pressure - loss was occurred at the ahead part of half pipe. the pressure uniformity reduced with orifice aperture ? increasing, and the relationship between pressure uniformity and initial water pressure was poor. running under the initial water pressure of 1. 5 meter, the discharge uniformity reduced with orifice aperture ? increasing, and when the orifice aperture smaller than or equal 1. 0mm, irrigation uniformity could achieve above 0. 6

    ( 3 )通過對空氣介質中簡易地下滴灌的微孔試驗研究發現: 60m長的平均壓力頭的位置基本上在距第一孔口的有效長40 - 45的地方;大部分頭損失發生在的前半部分;壓力均勻度隨孔徑的增大而減小,但與初始工作頭關系不密切;在1 . 5m以下的工作壓力下運行,沿程出均勻度隨孔徑的增大而降低,當孔徑不大於1 . 0mm時,灌均勻度可以達到60以上;當孔徑大於等於1 . 2mm時,灌均勻度低於50 。

  6. ( 3 ) based on the experiments data, it has been found that if the emitter discharge of sdi was little, the depth of pipe buried should be shallow, and the distance between two micro holes should be chosen to equal or close the distance between two lateral pipes, if the emitter discharge of sdi was great, the pipe may be buried deeper, and the distance between two micro holes could be greater than the distance between two lateral pipes
