A deck corresponding with earthworm case is fixed with the casing, the earthworm case is caught in deck； Several humidity sensors are uniformly fixed with the box inside wall, a controller, institute are fixed with the casing lateral wall State and an electronic humidifier is fixed with casing, the humidity sensor is electrically connected to controller input, the electronic humidifier It is electrically connected to the output end of controller.

A clipboard for carrying recording sheet, the case are removably placed with the basis of such scheme, in the casing It is fixed with a pen container in vivo.

On the basis of such scheme, two relative U-shaped card blocks of opening are fixed with the side side wall in the casing, two The card chamber corresponding with clipboard is formd between individual fixture block, the clipboard both ends are respectively clamped into the fixture block of both sides.

On the basis of such scheme, a LED illumination lamp is fixed with the box inside wall, the LED illumination lamp is electrically connected It is connected to controller.

On the basis of such scheme, the both ends of three plates of creeping form path clearance between box inside wall respectively.

The utility model has an advantageous effect in that compared with prior art：Experimental provision provided by the utility model, its The different plate of creeping of three surface roughnesses is embedded in tank floor, an earthworms for experiment in earthworm case is taken out, Creeped the identical time on three plates of creeping respectively, record its distance creeped respectively in three plates of creeping, embodied with this Earthworm is very fast in which type of body surface motion.Meanwhile the humidity in casing is monitored and controlled, to keep earthworm body Body humidity, there is provided suitable humidity environment.

Embodiment

In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining The utility model, it is not used to limit the utility model.

Understand referring to Figures 1 and 2, culture soil layer is spread in a kind of Bioexperiment device, including an experimental box 1 and an inner chamber Earthworm case 2, earthworm just supported in the culture soil layer of earthworm case 2.The experimental box 1 includes casing 11 and casing The case lid 12 of 11 retractable connections, the casing can be made from transparent material, with from facilitating outside experimental box in casing it is real Test situation.A deck 4 corresponding with earthworm case 2 is fixed with the casing 11, the earthworm case 2 is caught in deck In 4.

The plate 3 of creeping of three cross direction profiles, the both ends difference of three plates 3 of creeping are embedded with bottom surface in the casing 11 Path clearance 13 is formed between the madial wall of casing 11, the upper surface for creeping the upper surface of plate 3 and the bottom surface of casing 11 is flush, Length scale line 34 is equipped with the upper surface of plate 3 of creeping, this three plates 3 of creeping, which include being respectively placed in both sides first, creeps plate 31 and the 3rd creep plate 33 and be placed in first creep that plate 31 and the 3rd is creeped between plate 33 second creep plate 32, described first The upper surface of plate 31, the second the creep upper surface of plate 32, the 3rd roughness for creeping the upper surface of plate 33 of creeping reduce successively.

Several humidity sensors 5 are uniformly fixed with the madial wall of casing 11, are fixed on the lateral wall of casing 11 There is a controller 6, an electronic humidifier 51 is fixed with the casing 11, it is defeated that the humidity sensor 5 is electrically connected to controller 6 Enter end, the electronic humidifier 51 is electrically connected to the output end of controller 6.Humidity in casing 11 is monitored and controlled, Humidity in casing is maintained in certain convenient scope, to keep earthworm body humidity, there is provided suitable humidity environment.
