Abstract

A soil saturated hydraulic conductivity automatic measuring apparatus is disclosed. The apparatus comprises a water supplying device, an infiltration device, an infiltrated water receiving and measuring device and a pedestal. The water supplying device is mounted on the pedestal and is provided with a water inlet and a water outlet. The infiltration device comprises an upper cutting ring, a lower cutting ring, a perforated plate and a funnel. The upper cutting ring is connected to the water supplying device. The perforated plate is mounted at the bottom of the lower cutting ring. The upper cutting ring and the lower cutting ring are connected and then fixed onto the funnel. An automatic lifting rack is disposed on the pedestal. The funnel is fixed to the automatic lifting rack. The infiltrated water receiving and measuring device comprises at least three graduated cylinders having a same volume and a disk rotating at regular time. The rotating time of the disk rotating at regular time can be set. One time of rotation allows one of the graduated cylinders to be right under the funnel. The apparatus has characteristics of a simple structure and operation convenience, can automatically achieve water feeding and infiltration water receiving functions, increases accuracy of measuring results and is high in automatic degree, simple in operating method, low in cost and convenient in popularization and application.

Description

technical field [0001] The invention relates to a measuring device for measuring soil parameters, in particular to an automatic measuring device for soil saturated hydraulic conductivity. Background technique [0002] The water content and its migration characteristics in the soil affect soil fertility and play a decisive role in plant growth. Determining the relevant parameters is the basis for rational irrigation, improving the root zone environment of plants, and increasing agricultural production. Among them, soil saturated hydraulic conductivity is particularly important. It is one of the important physical properties of soil. It is an important soil parameter for calculating the flux of water in soil profiles and designing irrigation and drainage systems. It is also an important element in hydrological models. parameter, its accuracy seriously affects the accuracy of the model. Soil saturated hydraulic conductivity is the amount of water passing through a unit area pe...
