摘要
讨论了目前土壤蒸发的测定和计算方法及主要影响因素;对冬小麦农田棵间蒸发量的研究现状进行了分析。分析认为,当叶面积指数较大时,棵间蒸发的现有研究结果尚存在较大的差别,而且高频灌溉条件下的土面蒸发有待于进一步研究。
The methods of the measurement of surface evaporation and influencing factors were discussed.The research progress on surface evaporation was also analyzed.In conclusion,there were some differences in the results of soil surface evaporation,when the leaf area index was large.A further study was needed under high-frequency irrigation.
