  1. 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。
  2. 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。
  3. The parasitic thermal energy produced combined with the electricity that is generated make the treatment plants self - sufficient and wastewater from sewage treatment works can be purified to industrial water quality for reuse as irrigation water or can be treated to even higher quality standards if required

    產生的熱量與生成的電能相結合使處理工廠可以自給自足，廢水通過污水處理系統凈化后可以達到工業用水質量並做為灌溉水重新使用，或者處理為符合更高質量標準的用水（如果需要） 。
