Problems solved by technology

[0002] The underground observation room currently used for farmland experiments is made of concrete and steel bars. Usually, the required sensors and soil solution extraction equipment are installed on the cement wall of the groundwater observation room. This traditional underground observation room exists The disadvantage is that the function is simple and it is only used to monitor a certain indicator, such as soil profile moisture, salinity, temperature or nutrient concentration, etc.

Embodiment

[0021] Example: such as figure 1 As shown, a multifunctional underground observation room of the present invention, the inner side wall of the underground observation room is 31.9m long, 1.8m wide, and 2.6m high. They are all 1.1m high, 0.9m wide, and 12mm thick. Each observation window is equipped with different observation equipment. A detection sensor or a sampling head connected to a sampling device are respectively arranged on the circular holes.

[0022] There are 14 observation windows, of which No. 1-8 is a group, such as Figure 4 As shown, there are two rows of round holes with a diameter of 4 cm vertically along the tempered glass surface of the window, one row is 4 round holes, the center of the round holes is 18 cm, 28 cm, 38 cm, 48 cm from the upper edge of the glass, and the other row is 9 cm. A round hole, the center of the round hole is 8cm, 18cm, 28cm, 38cm, 48cm, 58cm, 68cm, 78cm, 88cm away from the glass top respectively, and a sealing plug 18 with a hole in

Abstract

The invention relates to a multi-purpose underground observing room, belonging to the technical field of soil monitoring. According to the invention, a plurality of transparent tempered glass observation windows are arranged on the side wall of the multi-purpose underground observing room, provided with different observation devices, and directly communicated with an external soil body, and a plurality of round holes are respectively formed in transparent tempered glass of the observation windows, and are provided with detection sensors or sampling heads connected with the sampling devices. According to the invention, the transparent tempered glass is adopted, and the observation devices are placed in the underground observing room, so that the moisture, temperature, conductivity, pH and ion change of soil at different depth can be accurately monitored, and meanwhile, the color change, the form change, the interior physical property change and the interior chemical property change, as well as the change of the soil physicochemical property and the crop root morphology change above and below a straw layer during the decomposition process of straw can be observed; and the multi-purpose underground observing room has the advantages of convenience in observation and large quantity of measurement items.
