滴灌和滲灌系統一般也用於盆栽灌水。Low pressure trickle irrigation is based on the little effect of pressure on the quality of drip irrigation system
壓力水頭對滴灌系統的灌水質量影響很小,這為低水頭滴灌提供了理論依據。Trickle irrigation is regarded as a significant technology of water - saving irrigation, because we can exactly control the quantity of irrigation water, decreasing ground evaporation and deep - seated leak
滴灌系統作為一種優秀的節水灌溉技術,它能夠精確的控制灌溉水量,減少地面蒸發和深層滲漏。When the area of little irrigation district is constant, drip line of trickle irrigation has the optimizing length. if the length of drip line is longer or shorter than the optimizing length, the expense of trickle system increases
一般認為,毛管長度越長,則滴灌系統造價相應就會減少,因此,在優化設計時,通常認為毛管取最大長度。Many factors have effect on irrigation uniformity. with the growing of pressure, how is irrigation uniformity of trickle irrigation varying on different condition of the diameter of drip line, the distance of emitters, the length of drip line, the style of emitters, the flux ratio of emitters and the face gradient of little irrigation district. the consequence shows that pressure has puny effect on irrigation uniformity
滴灌系統的灌水均勻度受眾多因素的影響,本文通過毛管的管徑、滴頭間距、毛管的管長、灌水器的類型和灌水器的流量系數不同的情況下,灌水均勻度隨壓力水頭變化模擬結果顯示,壓力水頭對灌水均勻度影響非常小。Finally, the expert system is used in ming wang ta village, lin county, shanxi province to design and project for apple ' s drop irrigation at the demonstration farm. by the aid of the system, the calculation result, the design result, the drawing of pipe framework, the budget sheet are conveniently gained, and efficiency is distinctly enhanced. the result of this design has been successfully carried out in the test areas
最後應用本系統對山西省臨縣城莊鄉明旺塔村丘陵山區截流蓄水灌溉工程試驗示範節水灌溉試驗示範區的果樹滴灌灌區進行規劃設計,方便快捷地獲得了該滴灌系統比較合理計算結果、規劃和管系結構圖、概算表等,明顯提高了設計的效率,設計過程具有較高的參考性與實用性。When other factors are unchangeable, with the growing of the diameter of drip line and the distance of emitters, irrigation uniformity of trickle system is increasing. the face gradient of little irrigation district has complex effect on irrigation uniformity. in a word, we tries our best to make the face of little irrigation district flat in order to improve the quality of drip - irrigation system
灌水均勻度由某一因素決定,而其它因素不變的條件下,隨管徑增大,滴灌系統的灌水均勻度增大;隨滴頭間距增大,灌水均勻度也在增大;地形坡度對灌水均勻度影響比較復雜,為了提高低壓滴灌的灌水質量,土地必須整平。In a short, answer to the optimizing length of porous pipe is very important in optimum design of trickle system
毛管和支管的直徑以及設計壓力水頭一定的情況下,大於或小於毛管的經濟長度,都會使滴灌系統的費用增加。Within 10 years i expect that low - cost drip systems will irrigate several million hectares in india alone, an amount larger than the total worldwide area under drip irrigation today
我預期在10年內,光是在印度,就有數百萬公頃的土地是利用這種廉價滴水系統來灌溉的,比起現今全世界利用滴水灌溉的農地面積,還要大出許多。Guidelines for plugging hazards of drip irrigation systems are presented ( table11 )
