在农田灌溉排水生产实践中,常需要在野外现场测定有关参数,如土壤含水率,土壤水势(亦称土壤负压),土壤溶液浓度、土壤温度等。为了适应这种需要,国外已生产有多种适用于野外操作便于携带的数据采集器(如美国Omnidata公司生产的Polycorder),我国农田灌溉排水的室外测试技术还比较落后,基本上停留在繁重的人工观测阶段,为此,在水利水电技术发展资金的资助下,我们研究了例携式多点多参扫描仪。现报道如下:
In the practice of farmland irrigation and drainage, it is often necessary to determine the relevant parameters in the field, such as soil moisture content, soil water potential (also known as soil underpressure), soil solution concentration, soil temperature and so on. In order to meet this need, a variety of data acquisition devices suitable for field operations such as Polycorder manufactured by Omnidata Corp. have been manufactured in foreign countries. The outdoor testing technology of irrigation and drainage in China is still relatively backward and basically stays in the heavy In the manual observation stage, for this reason, with the funding of the development fund of water conservancy and hydropower technology, we studied the example of portable multi-point multi-parameter scanner. Reported as follows now:
