耗水量是指作物整个生长期的生理需水(包括吸收水分及通过叶面蒸腾的水分在内)与田面蒸发量的总和,一般认为它与气候、土壤、水文及农业耕作管理措施等条件有密切的关系。随着农业生产的发展,新品种、新技术以及科学种田的水平不断提高,迫切需要研究高产小麦的田间耗水情况。根据近几年来我们在咸阳周陵公社和咸阳地区农科所的观测资料,结合对高产单位的调查,对高产小麦的耗水量进行初步的分析总结。
Water consumption refers to the sum of the physiological water requirements (including the water absorption and the transpiration of water through the foliage) and the evapotranspiration during the whole growth period of the crop. It is generally considered that the conditions such as climate, soil, hydrology and agricultural tillage management are close relationship. With the development of agricultural production, new varieties, new technologies and scientific farming are constantly improving, so there is an urgent need to study field water consumption in high-yield wheat. According to the observation data of the Commune of Zhouling in Xianyang and the Agricultural Science Institute of Xianyang Prefecture in recent years, the water consumption of high-yielding wheat is analyzed and summarized based on the investigation of high-yielding units.
