Description

A small lysimeter

technical field

The utility model relates to a soil data measuring device, in particular to a small lysimeter.

Background technique

When the existing small-scale lysimeters detect soil data, the reverse osmosis membrane mostly uses a flat plate, and some of the water leaked in the soil will accumulate on the surface of the reverse osmosis membrane. At this time, there are errors in the measured soil gravity data, which is easy to It affects the calculation of evapotranspiration; the connection of related sensor lines on the lysimeter is cumbersome, and the data transmission is inconvenient, which is not conducive to observation and analysis; the existing small lysimeter is not convenient to use alone, which affects its popularization and application.

Utility model content

The purpose of the utility model is to provide a small lysimeter with convenient use, accurate detection and expandable functions for the problems existing in the prior art; it is convenient for comprehensive analysis of soil data.

The technical scheme that the utility model adopts for realizing the above object is:

A small lysimeter, comprising a cylindrical container, a leakage device and a weighing base, the leakage device includes a frame body, a spherical reverse osmosis membrane, a drainage rod and a diversion funnel; the cylindrical container, the leakage device and a weighing base The heavy base is connected up and down in sequence. There are multiple sensor jacks on the cylindrical container. The frame is connected between the cylindrical container and the weighing base. The spherical reverse osmosis membrane is set on the upper end of the frame. At the lowest end under the membrane, the diversion funnel is connected to the frame body, and the diversion funnel is located under the drainage rod;

Further, the drainage rod is conical;

Further, the lysimeter also includes a liquid crystal display device, the liquid crystal display device is electrically connected to the weighing base, and the liquid crystal display device is provided with a soil temperature sensor, a soil moisture sensor, a soil water potential sensor, a soil salinity sensor, and a soil profile carbon dioxide monitoring device. Sensor data input interface, and data output interface.

The beneficial effects of the utility model are:

The utility model adopts the combination of the spherical reverse osmosis membrane and the drainage rod to guide the water flow, avoiding the problem of water accumulation on the surface of the plane reverse osmosis membrane; the drainage rod is conical to facilitate the water drop; the liquid crystal display device can display the weight data from time to time, and can also collect soil The temperature sensor, soil moisture sensor, soil water potential sensor, soil salinity sensor, and soil profile carbon dioxide monitoring sensor data are displayed for easy observation and analysis. The liquid crystal display device can also transmit the collected data to other devices, making the lysimeter Instruments can be used alone or in combination.
