植物工厂光照和温度调控（Plant lighting and temperature regulation） Plant lighting and temperature regulation A plant is a system for annual production of plants in a closed or semi enclosed growth environment with high precision. A suitable growth environment for target crops is required within the system. These include: environmental factors (light intensity, light quality and light hours), temperature, humidity, wind speed and the concentration of CO2, pH, EC nutrition and fertilizer composition, oxygen content, temperature and velocity of liquid. Environmental optimization control of plant factory, the most fundamental is to clear the relationship between crop photosynthesis, product accumulation, distribution, development and bypass respiratory physiological process and environmental factors, considering the composite effects of various environmental factors, choose the control means of low operation cost, good effect of optimized control, to control the effect to achieve the ideal. Here, we mainly introduce the illumination and temperature regulation of the plant. Light environment control technology Light is the energy source of crop life, and also important information for some crops to complete the life cycle. Whether weak light, short sunlight or strong sunlight, long sunshine may be the limiting factor for the growth and development of some crops. Therefore, it is necessary to regulate and control the light environment in the plant. The regulation of light environment is based on the species and growth stages of crops, and through certain measures to adjust the light conditions, and create a good lighting environment, in order to improve the photosynthetic efficiency of crops. Light regulation of photosynthetic light cloudy at high latitudes or even, resulting in insufficient number of light intensity and light, or the whole crop has higher light intensity requirements, it is necessary for photosynthetic light. It is an effective method to use artificial light source
