要改变传统的灌溉方式，推行现代精准农业，没有稳定、可靠、精确的土壤湿度探头就无法保证智能化节水灌溉的实施．文章提出了通过研发不同形状的土壤湿度探头来提高其灵敏度和精准度，并对这些探头进行了实验研究．结果表明，内“W”形土壤湿度探头和工字形土壤湿度探头检测到的电阻值最小，矩形探头检测到的电阻值最大．内“W”形土壤湿度探头能有效减小因土壤收缩引起的电阻值测量偏差，提高灌溉控制系统精度．

To change the traditional irrigation methods to promote the modern water-saving agriculture, it has to develop a reliable, stable, and accurate soil moisture probe to support the implementation of water-saving irriga- tion technology. In this paper, the soil moisture probes of different shapes have been developed to improve its precision and sensitivity. Experimental results show that resistance detected by the W-shaped moisture probe and the I-shaped moisture probe is minimum, but the rectangular moisture probe is maximum. The W-shaped moisture probe can decrease resistance measured deviation which is caused by soil shrinkage.
