Soil Water Sensor Placement for Precise Irrigation Scheduling Using Soil Moisture Information
摘要
Abstract
In this paper, simulating experiment was used to study the effect of irrigation treatment based on soil water sensor at different soil depth on the biological characteristics and water use efficiency of the win-ter wheat. Results show that scheduling irrigation using 10 cm probe can save more water, meanwhile, the biological characteristics and water use efficiency of the winter wheat are all reach the best condition. Due to the experimental winter wheat was in earlier growing stage. However, when the root deeper than 30 cm with the extension of the growing stage, the depth of root water uptake is increasing, buried depth of the probe need more detailed research in the field, so as to achieve the goal of precise irrigation.关键词
