Description

Technical Field

[0001] This utility model relates to the field of plant cultivation equipment technology, specifically to a plant comparative test cultivation chamber. Background Technology

[0002] The plant comparative experiment cultivation chamber is the core device for conducting research on plant growth characteristics. It is mainly used to provide a controllable growth environment for different plant varieties or different treatment groups of the same variety (such as differences in fertilization amount and photoperiod) in order to analyze the influence of environmental factors on plant growth.

[0003] In existing technologies, traditional cultivation chambers mostly adopt open or simple closed structures, which have the following significant drawbacks: First, the planting space is divided in a fixed way, making it impossible to flexibly adjust the planting area or isolation conditions of each area according to experimental needs; second, the environmental control modules (light, temperature, and humidity) are mostly controlled as a whole, making it difficult to achieve precise adjustment of individual areas, leading to deviations in comparative experimental data; third, the observation windows are mostly fixed structures, unable to adapt to the observation needs under different light conditions (such as strong light / weak light). Therefore, there is an urgent need for a plant comparative experimental cultivation chamber with a flexible structure and precise control. Utility Model Content

[0004] The purpose of this invention is to provide a plant comparative experiment cultivation chamber that solves the problems of fixed planting space, inaccurate environmental control, and limited observation conditions in the prior art through modular design, zoned control structure, and sliding observation device.

[0005] The technical solution provided by this utility model is a plant comparative experiment cultivation chamber, including a chamber body. The front of the chamber body is an open structure. The interior of the chamber body is provided with a main frame. The main frame is an L-shaped hollow frame with multiple planting troughs for cultivation on its upper part. The main frame is provided with a vertical guide frame between the planting troughs. The inner side of the vertical guide frame is inserted with a partition plate. The side of the chamber body opposite the open structure is provided with growth scale lines. The top of the chamber body, above the planting troughs, is provided with an independently controlled light module, irrigation module, and temperature control module.

[0006] In a preferred embodiment of this invention, a baffle is provided in front of the planting trough at the open structure of the storage compartment. A transparent observation plate, matching the number of planting troughs, is embedded inside the baffle. A black light-shielding plate of the same size is provided outside the observation plate. Both the observation plate and the light-shielding plate are connected to the baffle via a sliding mechanism. The observation plate and the light-shielding plate are fixed to the baffle by spring clips.

[0007] As a preferred technical solution of this utility model, the vertical guide frame is an L-shaped structure, and its end is connected and fixed to the main frame through a U-shaped connecting groove. The external shape matches the internal shape of the silo. The inner side of the vertical guide frame is provided with a limiting slot that matches the shape of the partition plate.

[0008] As a preferred technical solution of this utility model, the partition plate is a composite structure plate, with the base plate in the middle and heat insulation plates on both sides.

[0009] As a preferred technical solution of this utility model, the bottom of the main frame is provided with a water collection tray for collecting water and soil seeping from the planting trough. The water collection tray is matched with the length of the silo body and can be slid out from one side of the silo body.

[0010] As a preferred embodiment of this invention, the planting trough is equipped with a humidity sensor and a temperature sensor for monitoring, and the growth scale line is located above the planting trough.

[0011] As a preferred technical solution of this utility model, the lighting module and the irrigation module are integrated into a single lamp body. The outer side of the lamp body is a ring-shaped lighting module, and the inner side is an irrigation module. The lighting module is a ring-shaped LED light strip with an adjustable spectrum, and the irrigation module is a mist nozzle.

[0012] As a preferred embodiment of this utility model, the temperature control module is a heating lamp disposed on both sides of the lamp body.

[0013] The advantages of this utility model compared with the prior art are as follows:

[0014] 1. Flexible spatial division: Through the combination of the L-shaped main frame and the pluggable partition plate, combined with the limiting slot of the vertical guide frame, the division position of the planting trough can be adjusted according to the experimental needs to adapt to the planting area requirements of different varieties or treatment groups; the composite material partition plate (middle base plate + heat insulation layer on both sides) effectively avoids temperature interference between areas and improves the accuracy of comparative experiments.

[0015] 2. Precise control by zone: The top-integrated independent control module for lighting (adjustable spectrum LED light strip), irrigation module (mist nozzle), and temperature control module (heating lamp) can individually adjust the light intensity, spectral composition, water volume, and temperature for different planting trough areas, meeting the environmental control requirements of multivariate comparative experiments.

[0016] 3. Convenient observation under multiple conditions: The sliding observation plate and the light-blocking plate at the baffle are fixed by spring clips. The light transmission (observing plant morphology) or light blocking (simulating a low light environment) state can be switched according to the experimental stage. In conjunction with the growth scale line above the planting trough, the plant height, leaf area and other indicators can be quickly measured.

[0017] 4. Efficient cleaning and maintenance: The bottom sliding water collection tray can collect water and soil seeping from the planting trough in real time. After the test, it can slide out along the side of the chamber for cleaning, avoiding cross-contamination and extending the service life of the device. Attached Figure Description
