在土壤水分张力计系统内嵌入一电子式温度传感器，对管内温度进行实时监测，对照管内压力发现：以密封塞取代陶土头时，管内温度上升26.9℃内压力变化了14.6 Kpa。当实验盆钵内的土壤含水量相对不变时，负压计中的压力值仍然随着温度变化出现有规律的周期变动，温度上升22.2℃管内压力变化了7.4 Kpa。通过对采集管内张力数据进行补偿运算，对张力计系统的升温和降温阶段进行温度补偿，可有效对由温度变化引起的张力计系统误差进行校正。当测定间隔为4h、温差为18.1℃时，两点的张力相差仅0.278 Kpa，未做补偿的两点压力差达6.5 Kpa。说明在在土壤水分张力计系统内嵌入一电子式温度传感器能够有效校正温度变化引起的张力计系统误差，达到全天候实时对目标地区实现水分管理的目的。

When the electronic temperature sensor was incorporated into a system of soil water tension and the inside-tube temperature was monitored in real time, it is concluded that the inside temperature increased by 26.9 ℃ and the inside pres-sure changed about 14.6 Kpa, when the pottery soil was replaced by the sealing plug. When the soil water was relatively stable in the experimental salvers, the in-side pressure stil varied regularly with the temperature. When the inside tempera-ture increased by 22.2 ℃, the inside pressure varied about 7.4 Kpa. Through com-pensation calculation of the inside tension, the temperature in the warming and cooling periods was compensated, which was useful to correct the tension mea-surement errors induced from the changing temperature. When the measuring inter-val was 4 hours and the temperature difference was 18.1 ℃, the tension difference of both points was only 0.278 Kpa, compared to the difference up to 6.5 Kpa be-fore compensation.
