The light incubator is an important life science instrument that plays an important role in the study of animal and plant life patterns. Rice is an important variety of food crops. During the growth process, rice can grow and develop better under good conditions of temperature, humidity and illuminance, and obtain high yield and good harvest. Therefore, the use of light incubator to study the application of light to rice growth can further explore the mystery of rice growth and provide data support for the optimization of rice growth conditions. Rice is a kind of photosynthesis plant. Only under the catalysis of light, rice can carry out normal photosynthesis and exchange of substances. Therefore, it can be said that rice can not grow and develop without light. In the course of the study, we studied the effects of light time on rice growth and the effect of light intensity on rice growth. The first operation is to set the illumination intensity of the light incubator to be the same, set different illumination time, and then observe the growth of the rice separately; the second operation is to set the illumination time of the illumination incubator to be the same, and set different illumination intensity. Then observe the growth performance of rice separately. Through light culture incubator research, it is found that the illumination time is too long or too short, which is unfavorable to the growth and development of rice. The excessive light intensity is too weak for rice growth. At the same time, through research, we can find suitable illumination time and light intensity for the growth of rice. In the process of scientific production in the future, we can regulate according to the results of this research, promote the growth and development of rice, and increase production and income. Rice is widely cultivated in many areas of China. The geographical location is different, so the light time and light intensity are also different. Therefore, in order to adapt to the growth requirements of different areas, in the breeding of varieties, it is also possible to use light incubators to cultivate different areas. Long-day and short-day rice varieties are used to ensure the yield and quality of rice cultivation.
