摘要
作物蒸发蒸腾量的测量与估算在农业方面有着重要的作用。本文主要介绍了作物蒸发蒸腾量的直接测定方法与估算方法,并在此基础上着重分析了各种方法的测量原理及其优缺点。目的在于能够在各种方法研究的基础上扬长避短,在以后的研究中找到一种适用于各种情况,准确测量作物蒸发蒸腾量的标准方法。
It is very important of the measuring and estimating methods of the crop evapotranspiration in agricultural.This article mainly introduces the measuring and estimating methods and its measuring principle,advantage and disadvantage of the crop evapotranspiration.Main purpose is to find a accurate methods which can adopt to every places and every circumstances.
