土壤水分张力计又名负压计,在我国一些灌区、灌溉试验站和水文站等单位已使用多年。但由于一些地方不熟悉该仪器的操作技术,缺乏统一的技术规程,以致经常发生测试数据不准,操作失灵和损坏仪器的情况。为了提高使用技术,我司与有关单位共同研讨,制定了操作技术暂行规程,供参照执行(并提出修改意见)。 Soil moisture tension meter, also known as negative pressure meter, has been used for many years in some irrigation districts, irrigation test stations and hydrological stations in China. However, due to the fact that some places are not familiar with the operation technology of the instrument and lack of uniform technical regulations, the situation of inaccurate test data, operation failure and damage to the instrument often occurs. In order to improve the use of technology, our company and the relevant units to discuss, formulated the operating technology provisional regulations for reference implementation (and propose amendments).
