Device for culturing plant experimental materials

Abstract

The invention belongs to the technical field of plant physiology experiment, and discloses a device for culturing plant experimental materials. The device for culturing the plant experimental materials comprises an upper shell and a lower shell, wherein a culture medium is arranged in the shell. The device for culturing the plant experimental materials further comprises a water and liquid feedingmechanism, a carbon dioxide and oxygen releasing mechanism, an illumination regulating mechanism, a temperature regulating mechanism and a controller. A water and liquid feeding experiment, a carbon dioxide and oxygen releasing experiment, an illumination regulating experiment and a temperature regulating experiment can be performed respectively or simultaneously, and the device for culturing theplant experimental materials is also suitable for plant culture. The device for culturing the plant experimental materials has various functions, high intelligence and automation, high experimental convenience and high accuracy, and the performing of various plant culture experiments is achieved. Meanwhile, the device for culturing the plant experimental materials also has the advantages of simplestructure, convenient assembly and low manufacturing cost.

Description

technical field [0001] The invention belongs to the technical field of plant physiology experiments, and in particular relates to a plant experiment material cultivation device. Background technique [0002] In the study of plant growth, a lot of experimental work is required, for example, the functional verification experiment of the effect of plant root growth-promoting bacteria on plant growth and the evaluation experiment of the effect of plant-microbial joint bioremediation of heavy metals and other contaminated soil. Plant root growth-promoting bacteria refer to microorganisms that live in plant roots and root surfaces and can directly or indirectly promote or regulate plant growth. At present, the functional verification of the plant growth-promoting effect of plant root growth-promoting bacteria generally uses ordinary hydroponics or sand culture methods, and the experimental devices use simple glass bottles or plastic flower pots. Using ordinary plastic pots to ver...

AI Technical Summary

Problems solved by technology

Using ordinary plastic pots to verify the function of plant root growth-promoting bacteria, due to the limited soil water storage, repeated water replenishment in the later stage will increase the workload, and it is easy to introduce miscellaneous bacteria during the water replenishment process, resulting in inaccurate experimental results; Glass bottle hydroponics can avoid the interference of external bacteria, but the device has certain limitations, such as some plant root growth-promoting bacteria are not suitable for growth in water environment, or some plant roots cannot survive in water environment, and The water environment seriously affects the growth-promoting effect of plant root growth-promoting bacteria, etc.

[0003] As can be seen from the above examples, many existing plant cultivation experimental devices have the following problems: one is that the function is single, and only a single type of plant experiment can be carried out; The third is that the degree of automation and intelligence is low, and a large amount of manual participation is required. This not only increases the workload, but also reduces the accuracy of the experimental operation, thus affecting the experimental results.
