摘  要：
依据FAO56作物需水量指南提供的作物系数计算方法,分别计算了内蒙古河套灌区磴口试验站小麦套种覆膜玉米、小麦套种未覆膜玉米、小麦套种油料向日葵3种套种模式下的综合单、双值作物系数。结果表明,3种套种模式下的作物在全生育期内均可迎来2次综合需水高峰;共生阶段的作物系数,单值方法高于双值方法的计算结果,而单一作物独立生长阶段,双值方法高于单值方法的计算结果;无论单值计算还是双值计算的套种作物田间综合ET,当单一作物处于独立生长期时差别不大,而2种作物共同生育阶段的差别较大;将3种作物在套种模式下的生育阶段划分的更加详细并分别命名,为套种模式下作物蒸散量提供更准确的计算依据。

摘  要：
Based on the method which was recommended by FAO, the single and dual crop coefficients for three interplanting modes(wheat interplanting maize with plastic film mulching, wheat interplanting maize without film mulching and wheat interplanting oil sunflower) were calculated respectively. The experimental station was located in Deng Kou, Hetao irrigation district in Inner Mongolia. The results showed that the three interplanting modes had two peaks of water requirement during the whole growth stage. Crop coefficient in coexistence stage showed that the single value calculation results were higher than the dual values approach, while it was contrary in a single crop growth stage. There was significant difference in the coexistence stage and little difference in the independent phase for a single crop whether single or dual crop coefficient approach to calculate the integrated ET for interplanting crops. The article provided more detailed birth stages division and named separately for the crops of interplanting mode, expecting to provide more accurate foundations of calculation for crop evapotranspiration of interplanting mode.
