冬小麦节水高效灌溉制度试验研究

Experiment and Research on High Benefit and Water-saving Irrigation Scheduling of Winter Wheat

通过冬小麦生长不同时期、不同土壤水分下限控制水平的灌溉试验,提出了冬小麦在当年水文和生产条件下的耗水规律、耗水量与产量的关系,提出了冬小麦试验年的优化土壤水分下限控制指标和灌溉制度,并对其研究方法也作了论述。

Through irrigation experiment that is carried out for winter wheat under its different growing period and under different level to control lower limit of soil moisture,the paper presents winter wheat's consumptive water use law,the relation between consumptive water use and yield under the condition of the year's hydrology and agriculture production,puts forward the optimum control indexes of soil moisture lower limit and optimum irrigation scheduling for this crop in the experiment year,and narrates the research method too.
