  1. Trickle irrigation conservers water where limited.

    滴灌在水少的地方應用起來可省水。
  2. Perspective analyses on film trickle irrigation application and the present status of treating alkali soil

    膜下滴灌技術應用與土壤鹽堿化治理的現狀及前景分析
  3. 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。
  4. Low pressure trickle irrigation is popular with farmers. currently, the study direction of drip system is to develop low pressure emitters

    當今，研製大流量的壓力補償式灌水器是低壓滴灌研究的方向。
  5. 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。
  6. In addition, similar analyses on soil water and salt characteristics in insufficient trickle irrigation were conducted. all these laid foundation for studying and analyzing the same problems in temperature fields

    此外，對滴灌非充分供水入滲過程的水鹽變化規律做了類似的分析，從而為考慮溫度梯度作用下的同類問題研究與分析打下基礎。
  7. 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。
  8. Drip irrigation under mulch is a advanced technique combined by the trickle irrigation technique and the polyethylene film planting technique, which have the advantages of saving water, enhancing yields, upgrading quality and high utility

    膜下滴灌是當今世界最先進的滴灌灌水技術和覆膜種植栽培技術相結合的產物，同傳統的灌水方式和栽培技術相比較具有節水、高產、優質和高效的優點。
  9. Distinct mankind ' s effect of the 60 ’ s, because of greatly opened up strategy implementation in the west in the near future, retreating the straw and limiting to pasture and usage of trickle irrigation, that each steps such as above and so on wholly shall benefit to the farming water amount to be saved, thereby add into the amount of flow in lake

    不同於上世紀60年代的人類活動作用的影響，近期由於西部大開發戰略的實施，退地還草、限制放牧、滴灌農業的推廣等措施都將有利於流域農業耗水量降低，從而增加入湖徑流量。這一階段湖泊水面急劇增加是氣候干濕變化的自然現象，與農業節水因素沒有顯著的關系。
  10. 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。
  11. 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。
