摘要
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。
Aiming at the situation of shortcomings of the traditional artificial irrigation system, and the low efficiency of irrigation water, the paper discusses the application of α value 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.
