摘　　要：气量法作为一种土壤含水量测定方法,具有便捷、快速、准确的特性。在这一理论基础上研制了气量体积法测定土壤含水量的仪器设备。根据实际生产检测需要设计出气量失重法土壤含水量快速测定装置,该设备相较于介电法,工作量小;相较于气量体积法更省力、更安全;相较于烘干法节省了大量时间,提高了效率,且准确度能达到1%以内。因此,此装置能兼顾土壤含水量测定的精确度与效率,有效地填补国内外这一领域的空白。As a method for determining soil water content,the gas volume method has convenient,rapid and accurate characteristics.Based on this theory,an instrument for measuring soil water content by volumetric volume method is produced.We designed a rapid determination device for soil water content based on the actual production test.Com⁃pared with the dielectric method,the device has a small workload;it is more laborsaving and safer than the gas volume method;Compared with the drying method,it saves a lot of time,is more efficient,and the accuracy can reach less than 1%.Therefore,the device can balance the accuracy and efficiency of soil water content measurement,and effectively fill the gap in this field at home and abroad.
