  2. At present, the studies about the controlled alternate furrow irrigation are focused on how it affects the water physiological indexes, water consumption and yields of crops. but, some problems suc h as the soil infiltrative parameters, irrigating water advancing, water redistribution in soil, calculation of crop water requirement and water consumption, and the upper and lower limit indexes of soil moisture, guiding a field irrigation after the controlled alternative furrow irrigation is implemented in field, have not been researched systematically and deeply. if these problems could not been solved commendably, the popularization of controlled alternate furrow irrigation will be affected

    然而，目前有關交替隔溝灌溉的研究還主要集中於這種灌水方式對作物水分生理指標、耗水量和產量的影響方面，而對大田採用這種灌水式后的土壤入滲參數變化情況、作物需水量與耗水量計算、以及指導大田灌溉的水分下限控制指標等與大田生產實際密切相關的幾個問題基本上還沒有進行系統的深入研究，而這些問題如不能得到很好地解決，勢必會對這種灌水方式的推廣應用產生嚴重的影響。
  3. Test and research of bubble irrigation for field crop planted in wide - row space

    大田寬行作物湧泉灌技術的試驗研究

    本文針對我國西部乾旱區的特大型灌區?河套灌區所具有的獨特水文水資源條件，選擇兩個典型區域分別進行了作物-水分關系和基於swap模型模擬的田間灌溉水有效性研究，以揭示和確立水分對乾旱區作物產量的影響和量化表達與淺地下水位灌區農田水分運移轉化規律和灌溉水對作物生長利用效率的評價方法，為河套灌區以節水為中心的技術改造和可持續發展提供理論基礎和技術支撐。
  5. The first part is about the computing of crop water requirements ( or crop evapotranspiration ) and net irrigation requirements ( nir ) of ten crops in bojili irrigated district. then the traditional irrigation schedules of winter wheat and summer maize, which are the main crops in bojili, were evaluated with simulating model isareg. third, the field application efficiency in the experimental areas was evaluated from three methods

    本文即是由灌區實測資料計算各種作物需水量，推求其凈灌溉需水量；然後通過模型檢驗現行作物灌溉制度是否具有合理性，並對田間灌溉系統進行評價，求其實際田間灌溉效率；最後由兩種不同灌溉制度方案的對比，確定試區合理的作物灌溉制度，在此基礎上求出各代表年的田間灌溉需水量和用水過程線。
  6. In the fourth part, the field irrigated water requirement were gotten based on the recommended irrigation schedules and irrigated areas often crops. in this paper, the reference evapotranspition et0 in three counties in bid was computed by penman - monteith method and the crop coefficients, kc of ten crops by kcisa model and the crop water requirements, etc, were computed simply by kc et0. meanwhile, four representative years by frequency analysis are gotten according to net irrigation requirements and planted areas of different crops in bojili irrigation district

    本文首先採用fao最新推薦的penman - monteith方法計算灌區的參照騰發量et _ 0 ，用kcisa按照fao的計算方法推求十種作物的作物系數k _ c ；由此基礎上計算出作物需水量et _ c ，根據結果分析了不同作物的需水規律；同時用作物缺水量nir （凈灌溉需水量）進行頻率計算，求出了灌區的四個代表年，並分析了代表年年內自然水分狀況和作物缺水規律。
  7. Application of kansched irrigation management system for field crop

    大田作物灌溉管理系統的應用
  8. Based on the review of national and international research results of slight saline water utilization, combined with the national 863 project " the study on the safety and effective use of slight saline water and regeneration water ", a salt water irrigation test was carried out to analyze salt - water transfer and its effect on crop physiological process and yields through the theoretical analysis and indoor and field experiment method

    本論文在借鑒國內外微鹹水利用研究成果的基礎上，結合國家「 863 」項目?微鹹水和再生水安全高效利用技術研究，針對微鹹水利用中存在實際問題，採取了理論分析與室內外試驗相結合方法，開展了微鹹水灌溉對土壤水鹽運移特徵以及作物生理指標和產量影響的研究，取得如下結論。
  9. Drip irrigation under mul : h is a new irrigation method, as utiliz e the advance of drip irrigation and plastic film cultivation technique. the conditions influenced crop water requirement are changed in drip irrigation under mulch, thus crop water requirement pattern is different from conventional irrigation forms. it is very useful to research field mulched crops water requirement pattern watering with drip irrigation

    膜下滴灌是地膜栽培與普通地表滴灌相結合的產物，在地膜覆蓋和滴灌的綜合效應下，作物的生長與在常規條件下不同，因此影響作物需水量的一些基本條件都發生了變化，對于膜下滴灌作物需水量和作物系數還需要做進一步研究。
  10. Under the situation of total irrigation water use decreasing greatly and it is essential to irrigate saline soil ( saline soil and salt soil area constitutes 65 % of the whole infield ), a saving irrigation experiment study was carried out in hetao irrigation area, and crop response to water and salt stress was studied by way of pot and field experiment

    本文在河套灌區總灌水量減少又要解決鹽漬化土地（占總耕地面積65 % ）灌溉問題的前提下，針對主要作物油葵，採用苗期盆栽和田間試驗相結合的方法進行作物水鹽脅迫響應研究。
