针对传统人工灌溉系统的不足以及灌溉用水效率低的情况，探讨α值法自动灌溉系统的应用。该系统是按照作物土壤适宜含水率为上、下限，通过蒸发皿的水位变化监控土壤含水率变化，调控电动蝶阀适时开关给灌溉区供水，适时适量灌溉，提高灌水利用率。
針對傳統人工灌溉繫統的不足以及灌溉用水效率低的情況，探討α值法自動灌溉繫統的應用。該繫統是按照作物土壤適宜含水率為上、下限，通過蒸髮皿的水位變化鑑控土壤含水率變化，調控電動蝶閥適時開關給灌溉區供水，適時適量灌溉，提高灌水利用率。

Aiming at the situation of shortcomings of the traditional artificial irrigation system, and the low efficiency of irrigation water, the paper discusses the application ofαvalue method automatic irrigation system. This system is taking the suitable soil moisture content of the crop as upper and lower limit, by evaporating dish water level monitoring soil moisture content changes, regulates electric butterfly valve switch to supply water to irrigated area, takes irrigation timely, and improves irrigation efficiency.
