• 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
  本文即是由灌区实测资料计算各种作物需水量，推求其净灌溉需水量；然后通过模型检验现行作物灌溉制度是否具有合理性，并对田间灌溉系统进行评价，求其实际田间灌溉效率；最后由两种不同灌溉制度方案的对比，确定试区合理的作物灌溉制度，在此基础上求出各代表年的田间灌溉需水量和用水过程线。
• 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
  本文首先采用fao最新推荐的penman - monteith方法计算灌区的参照腾发量et _ 0 ，用kcisa按照fao的计算方法推求十种作物的作物系数k _ c ；由此基础上计算出作物需水量et _ c ，根据结果分析了不同作物的需水规律；同时用作物缺水量nir (净灌溉需水量)进行频率计算，求出了灌区的四个代表年，并分析了代表年年内自然水分状况和作物缺水规律。
