The photosynthesis of plants is carried out on the leaves. The size of the leaf area affects the photosynthesis of the plants. In agriculture, farmers often do some measures to increase the light rate of the leaf area, such as topping and removing some leaves. Measurement of leaf area can be performed using a portable leaf area meter. The larger the leaf area during photosynthesis, the better, because photosynthesis for respiration is performed at the same time.
Photosynthesis of plants is affected by the intensity of light, but excessive light may cause potential harm to plants because strong light can inhibit photosynthesis and reduce the efficiency of photosynthesis and/or maximum photosynthetic rate. Inhibition, in severe cases, can also cause photooxidative destruction of the photosynthetic apparatus. Because of the photosynthesis of algae and plants, due to the large redox potential difference between the product and the reactants, as well as the participation of some excited-state intermediates, it is possible to produce reactive oxygen species and some oxidants are strong. Molecules, so that their photosynthetic organs may be damaged by photooxidation. Nowadays, the pollution of the environment has led to the thinning of the atmospheric ozone layer, which has increased the amount of ultraviolet light reaching the earth in the atmosphere. This has caused the photooxidative destruction of photosynthetic organs. By using a chlorophyll meter for measurement, it was found that the increase in ultraviolet light was eventually found. Chlorophyll content decreased a lot.
Chlorophyll content is the main reason that affects the light absorption of plants. Chlorophyll content can be measured using handheld chlorophyll meter. It is also because the change in chlorophyll content is affected by ultraviolet light in the environment. Therefore, the use of measured chlorophyll content to determine the single element in the soil needs to be strengthened.
