摘　　要：棵间蒸发是农田水量平衡中的重要组成部分,所以准确估算出农田棵间蒸发,对干旱半干旱地区水资源高效利用具有重要意义。微型蒸发器是估测农田土壤蒸发常用的方法,本文对微型蒸发器的使用方法进行了总结,并归纳了微型蒸发器在温室蔬菜、小麦、玉米等作物上的应用现状,温室内不同蔬菜的棵间蒸发量占总蒸散量的40%左右;玉米、小麦等大田作物的日棵间蒸发强度受耕作方式、品种、气象因素以及土壤中残膜的影响。同时发现了当前微型蒸发器在使用中存在的问题,垄作作物如何正确的使用微型蒸发器有待研究。并对微型蒸发器进一步的研究应用提出了建议。Evaporation between plants is an important part of field water balance,so accurate estimation of evaporation between plants is of great significance to the efficient utilization of water resource in arid and semiarid regions.Micro-evaporator is a common method to estimate the evaporation of farmland soil.This paper summarized the application methods of micro-evaporators and their application status on greenhouse crops such as vegetables,wheat,maize etc.The evaporation between plants of different vegetables in greenhouse accounted for about 40%of the total evapotranspiration;the daily evaporation intensity of field crops such as maize and wheat were affected by farming methods,varieties,meteorological factors and plastic film residues in soil.At the same time,current problems existing in the use of the micro-evaporators were pointed out,and how to use the micro-evaporators correctly for ridge tillage crops was discussed.Suggestions were given on further research and application of micro-evaporators.
