喷灌具有灌溉水利用系数高、灌水均匀度高、自动化程度高等优点。然而喷灌过程中一部分灌溉水不能进入土壤,进而引起了喷灌是否节水的争论。文章着重讨论了在以冬小麦为研究对象条件下,不同学者就喷灌对土壤结构、土壤水分养分分布转化规律、喷灌对冠层内温度、湿度变化规律、喷灌对作物生长的研究概况,为回答喷灌节水增产的科学问题提供一定依据。
Sprinkler irrigation has a high coefficient of utilization of water, irrigation uniformity, high degree of automation advantages. However, part of the irrigation water can not enter the soil during sprinkler irrigation, which in turn leads to debate whether watering is possible or not. This paper focuses on the study of winter wheat as a research object, different scholars on the soil structure, soil moisture and nutrient distribution of transformation law, sprinkler canopy temperature and humidity changes in law, sprinkler irrigation on crop growth profile, in order to answer sprinkler irrigation Water saving and increase scientific issues provide a basis.
