摘要
从作物需水量的测定和作物需水量的计算方法入手,介绍了获取作物需水量的几种途径,论述了作物需水量的理论发展过程,对作物需水的理论进行了系统的总结,提出了目前作物需水量研究方面的不足,对今后作物需水量的研究起到承上启下的作用.
From the measure of the crop water requirements and its calculation methods,some ways of access to the water requirements of crops are introduced,and the development process of the crop water requirements is expounded.The theories of crop water requirements are summarized,and the shortage of research on the crop water requirements in the pass is presented,which built a bridge between research on crop water requirements in future and the former.
