Spruce and red birch are one of the constructive species and pioneer species of subalpine coniferous forest, and have become the key population in the natural regeneration process of subalpine coniferous forest in southwest China. Due to the difficulty of natural restoration and regeneration after natural forest felling in the region, a large area of ​​degraded shrub vegetation was formed. The light box is an instrument that simulates the effects of time, temperature, and light on plants, and can simulate a good environment for plant growth. The visible light incubator has created an ideal hardware condition for the restoration of the vegetation of the deforested felled subalpine forest as soon as possible, and an important task for the implementation of the western ecological environment construction. Studies have shown that there are no shortages of seeds of key species such as spruce and red birch in the seed bank of cuttings, but the exposure of the environment to the settlement of vegetation after harvest has caused dramatic changes in the environmental conditions such as light, temperature, and water in the site. These adverse environmental conditions may be an important factor limiting natural regeneration.
Light intensity plays an important role in plant growth and morphological structure. Light has direct and indirect effects on plant growth. Light is achieved by affecting the photosynthesis of plants and the transmission of nutrients. It directly influences the effect of light on the morphogenesis of plants. It does not require light for the process of plant growth itself. As long as there are enough nutrients, the plants can grow in the dark. However, the plants that grow in the dark are not normal in shape. The plant that grows in the absence of light is a yellowing seedling. Indirect effects mainly refer to photosynthesis, photosynthesis of organic matter in the fixed air of carbon dioxide, which is the material basis for plant growth. In addition, the photosynthesis of plants is carried out in chlorophyll. When studying the photosynthesis of plants, we usually use the chlorophyll detector or the chlorophyll meter to perform the measurement. It can understand the plant's SPAD value in time. For each fixed CO2 of the plant leaves, about 468.6 kJ of light energy is needed, so the light affects the growth of plants by influencing photosynthesis. Just because the light intensity has a tremendous effect on the growth of the plant, the appearance of the light incubator becomes more meaningful. The light box can control the light intensity and time, and in a sense, it can control the growth of the crop and make the crops We expect the harvest.
Natural environmental protection is a hot topic that has become more and more popular nowadays. Although artificial excavation and natural environment protection are out of place, all available resources are utilized (depending on high-tech products: intelligent light incubators simulate the duration of light in the vegetation production process. , strength and other factors) can be achieved faster and better we can create a harmonious society of sustainable development of man and nature.
