The light box is also called the light incubator. It refers to an instrument controlled by a microcomputer to set the temperature, humidity, light intensity, daytime night and other related parameters of the plant growth. This instrument is set by man and set according to the best environment for plant growth. The LCD screen on the box surface can display the set temperature, humidity, and illumination, as well as the current temperature, humidity and light, so that the instrument can Run unattended. In addition, the light box this instrument is equipped with a full spectrum of plant growth lights, so that the light received in the box with the light received under natural conditions there is no significant difference. While beneficial to the growth of plants, it also improves the disease resistance of plants.
Positive plants are plants that grow robustly in strong light conditions and grow poorly under covert and low light conditions. Such as licorice, Atractylodes, peony, rehmannia, cassia, mint and so on. The light box will be able to control the light well, so that plants can fully accept the sunlight and carry out photosynthesis. Negative plants are plants that grow well under weaker light conditions than under strong light conditions. However, this does not mean that the weaker the light requirements of the negative plants are, the better, because when the light is too weak to reach the compensation point of the negative plants, it cannot grow normally, so the negative plants require weaker light. It is also only relative to positive plants. Negative plants grow more in moist, shady areas or in the jungle, such as Liancao, ginseng, Arisaema, and Coptis. A shade-tolerant plant refers to a plant that falls between two categories. This type of plant grows best under full sun, but it can tolerate moderate concealment, or it requires lighter shading during childbirth. Such as when the reference, Huang Jing, cinnamon, butternut and so on.
From the above we can see that different plants have different requirements for light. Therefore, we must adjust the appropriate illumination according to the characteristics of the plant. The intensity of illumination determines the speed of plant growth. We want to create a more excellent growth environment for plants. In nature, we use different recorders to determine the various parameters of the plant's growing environment. For example, a temperature and humidity self-recording device is used to record temperature and humidity, and sometimes it uses chlorophyll. Measuring instrument to determine the chlorophyll content of plant leaves, as well as the plant nitrogen content, to provide a more suitable environment for plant growth. In addition, if we have conditions, the light box will be a very good choice.
