In particular, the environment is changing due to various factors, and the rate of extinction of rare plant species is accelerating. To fully grasp the growth rules of each species (whether it is a crop, a cash crop, or a rare species), protect plant resources, and use plant development. With biogeography, studying the genetic variation and differentiation of plants and their relationship with the environment, studying the origin of plant organs and structures, the evolution mechanism of mutation and development mechanisms, and so on, all require a complete set of environmental simulation systems.This is not just the regulation of basic conditions such as temperature and light. Environmental stress simulation tests that simulate extreme conditions also require relatively strong control capabilities of the training equipment.
Secondly, according to the "environment", the factors to be investigated are different. Different plant species have different types of influencing factors. Even if the influencing factors are the same, the difference in environmental conditions of the place where the plant originates determines that the scope of the factor is different.
Light intensity, light type, light formula, temperature, carbon dioxide, and humidity control are several commonly used variables.
