The difference in illuminance will have some influence on the growth of the leaves, the developmental structure of the leaves, the photosynthetic capacity of the leaves and the photosynthetic pigment content of the leaves. The illuminance is generally given by sunlight. Although artificial lighting is now available in many places, most of them rely on sunlight. In the study of illuminance, we use photo quantum quantification to measure light quanta because light quanta are a unit of measurement that directly reflects the light intensity. In addition, there is a temperature illuminance recorder, and it is also possible to measure the illuminance. The measurement result is expressed in Lux. Our ceramic Force Control System, ceramic active contact flange, ceramic Constant Force Actuator have many advantages over other grinders. It can realize flexible grinding, quick repsond to surface changing, and instant adjusting. Traditional mechanic hand lacks flexibility, and it is not easy to adjust, hard to realize mass production.

Illumination has different effects on the growth of different types of Senna. The following are the results of our research: 1. Low light intensity can increase the leaf area of ​​common sweet cherimoya fruit and sweet fruit, but has no effect on the leaf area of ​​cherimopsis philippines. In addition, we also found that shading has the tendency to reduce the number of leaves and plots, leaf width, and leaf length of Annona simonii seedlings, but this difference is not significant. Shading will extend the growth period of the leaves and increase nutrient consumption. Illumination has little effect on the length of the blade and the growth pattern of the blade area. Compared with the natural illumination, the cover cathode significantly reduced the leaf thickness, palisade tissue thickness, and epidermis thickness of the leaves of Annona squamosa seedlings, and significantly reduced the thickness of spongy tissue, but shading reduced the thickness ratio of palisade tissue and spongy tissue. The relative increase in the thickness of the sponge tissue is explained. Shading had no significant effect on the thickness of the lower epidermis. 3. Compared with natural light, the total chlorophyll content in leaves of 'African Pride' seedlings with shade conditions increased significantly. This increase was mainly caused by a significant increase in chlorophyll a and carotenoid content due to changes in chlorophyll a content. However, the mass ratio of chlorophyll a to chlorophyll b was significantly reduced, indicating that the relative increase in the content of chlorophyll b was observed.4.The photosynthetic rate decreased with the decrease of illumination in the development environment, but the difference was not significant. The RuBiscol activity of chloroplast under non-extremely weak light has high stability, and the photosystem II of the plant leaf is not destroyed, but the activity is enhanced, the original light energy conversion rate is increased, and the low light increases the total chlorophyll, chlorophyll b and The content of carotenoids thus increases the ability of the leaves to capture light energy; on the other hand, it may be because the 'African Pride' seedling seedlings have a greater range of adaptation to light, and the shading conditions in the test have not yet reached their photosynthetic capacity. The natural light intensity produced a significant difference in the level of production of cattle.
It can be seen from the above that the effect of light intensity on Pansy is still quite large. How to control the light intensity? There are many kinds of light incubators on the market. The most important function of this instrument is to provide illumination on demand, including illumination time and light intensity, which greatly improves the utilization of light energy and also provides us with control over plant growth. Therefore, the light incubator is a scientific instrument that is very suitable for agricultural production.
