Effect of Light Intensity on Ornamental Plants Illumination is one of the necessary conditions for photosynthesis of plants. Without light, plants cannot carry out photosynthesis. Photosynthesis is the most important physiological activity of plants. It is a process in which plants convert inorganic substances into organic substances and store them. Only after this process can plants grow better and faster. However, there are great differences in light conditions in different application areas. Low light is not only unfavorable to the normal growth of the plants, but also has a certain influence on the original ornamental traits of the plants. Therefore, it is necessary to study the effects of light on plants. If it is necessary to control the light intensity in the process of plant growth, monitoring and analysis of the ambient light intensity can be performed through a small automatic weather station during planting, and external light sources can be used to control the light intensity of the environment. After 30 days of low light treatment, the fresh weight, dry weight and water content of the four leafy vegetables showed a tendency to decrease with the weakening of the light intensity. In terms of fresh weight, 4 leafy vegetables were reduced by 25.6%, 18.9%, 19.24%, and 43.7%, respectively, compared with the control at 30% light. Ziguan No. 1 Chinese cabbage, violet lettuce and butter lettuce had significantly different levels from the control ( P was less than 0.05); under 10% light, it decreased by 52.1%, 63.5%, 66.9% and 54.5%, respectively, compared with the control, and the difference with the control reached a significant level. In terms of dry weight, the 30% light intensity decreased by 55.4%, 43.2%, 37.0%, and 69.1%, respectively, compared with the control, and the difference with the control reached a significant level; the 10% light intensity decreased by 79.4% and 85.5%, respectively, compared with the control. , 76.8% and 75.8%, and the control differences reached significant levels. In terms of moisture content, the 30% light intensity increased by 4.5%, 4.8%, 1.7%, and 4.8% compared with the control. The difference between violet and lettuce was significantly higher than that of the control; the light intensity at 10% increased by 6.4% and 7.6, respectively. %, 2.3% and 5.3%, the control differences reached significant levels. This shows that the increase in the fresh weight of the material and the accumulation of dry matter are suppressed under low light, and the proportion of dry weight is also decreasing. This shows that in the process of plant growth, we need to use the field microclimate automatic observer to understand the changes of the surrounding environment at any time, especially the changes in light intensity. At the same time, according to the different growth stages of plants, the requirements of the environment are adjusted at any time. In this way, plants can grow in the best condition.
