  1. The study was primarily conducted to investigate the effects of various irrigation managements on the yield, quality and wue of alfalfa and the sustainable utilization of soil - water in north china plain. five treatments were applied : 0mm, 30mm, 50mm, 75mm and 100mm irrigating at the beginning of the second growth cycle in 2001

    本研究通過兩年的灌溉實驗，根據對降水情況、土壤水分的蒸發量、蒸散量與苜蓿各生物學指標的分析，初步探討了在華北平原地區不同灌溉處理對于苜蓿產量、品質、水分利用率以及苜蓿地土壤水資源利用可持續性的關系。
  2. The efficiency of irrigation in the beginning of the growth cycle in arid season distinctly surpassed the average wue. twelve treatments of combining different times and amounts of irrigation were applied in 2002

    灌溉處理並不能引起同茬同品種苜蓿的蛋白質含量出現差異；但是在第二茬初期灌溉，能在雨季來臨前搶收到更多的優質苜蓿。
  3. Water resources management system is one of key factors to restrict high efficient use of water resources, self - financing irriagation and drainage district is a new - type model on water resources management in countryside, distribution and engineering management generalized by world bank in china, by constructing water supplying company or water supplying units and water using association, establishes water supplying, using water, engineering management systems and institutions according with economic mechanism oriented to marketing to realize self - financing and good cycle, high efficient use of water resources, good running of engineering, so that it promotes sustainable development of middle - small irrigation works and irriagation district

    水資源管理體制是制約水資源高效利用的關鍵因素之一。經濟自立灌排區（ sidd ）是世界銀行在我國推廣的一種新型的農村水資源管理、分配及工程管理的新模式，它通過組建供水公司（ wsc ）或供水單位（ wso ）和農民用水者協會（ wua ） ，建立符合市場經濟機制的供水、用水、工程管理體系和制度，實現灌區的經濟自立和良性循環，實現了水資源的高效利用和工程的良性運行，使農村中小型水利工程和灌區能持續發展。
  4. Soil water infiltration is aimportant link in nature water cycle, study on soil water infiltration may make sure reasonably farmland irrigation technical parameter to offer science reference

    土壤水分入滲是自然界水循環中的一個重要環節，土壤水分入滲問題的研究，可為合理確定農田灌溉技術參數提供科學依據。
  5. Irrigation water requirement per time = ( soil water irrigation maximum - soil water irrigation minimum ) ? scheming wetted soil layer depth. irrigation cycle and irrigation times were decided by soil water irrigation maximum, minimum and consumption velocity

    灌水周期和灌水次數由灌溉飽和點與補償點及土壤水分消耗速率決定，表現為強耗水期灌水周期短，灌水次數多，其後依次按中、弱、微耗水期灌水周期增長，灌水次數減少。
  6. The green revolution of the 1960s and 1970s introduced high - yield grains, irrigation and fertilizers, which ended the cycle of famine, disease and despair

    1960和1970年代的綠色革命提高了農獲量，改進了灌溉系統和肥料，終結了饑荒、疾病和絕望的惡性循環。
