作物需水量计算方法研究

Research on the Calculation Methods of Crop Water Requirement

介绍了作物需水量的影响因素,并针对这些影响因素将作物需水量的计算方法分为3类,每类选取有代表性的几种方法进行探讨,指出它们的优缺点和适用条件,对今后的作物需水量研究有重要的参考价值。

The factors that would affect the crop water requirement would be discussed. Based on these factors, the methods of determining the crop water requirement were attributed to three species. Then a few typical methods would be selected from each of the three species for further investigation aiming at revealing their advantages, shortcomings and application conditions ; which would provide reference to the future research about crop water requirement.
