Study on Photosynthesis Conditions of Orchard Fruit Trees by Accumulation Light Calculation Software
Research on the photosynthesis of fruit trees has been deepened both at home and abroad. In particular, there are many reports on photosynthesis of deciduous fruit trees. For sweet oranges, the photosynthetic characteristics of the tree in particular under natural conditions have not been systematically studied. In the past, the column was studied on the basis of angle plugs and used to test the fruit in the full fruit period. The purpose is to explore the properties of photosynthetic production under natural conditions. Find out the measures to make full use of the potential of photosynthesis to provide theoretical references, and lay the foundation for further research on the mechanism of citrus photosynthesis. Photosynthesis of plants needs to look at the relevant parameters of the accumulated light, and the accumulated light calculation software can effectively calculate the accumulated light and provide more help for the research work. WeChat sweep to get more professional information: Sodium Formate is also called sodium formate. The crystal contains two crystal waters, so it is also called sodium formate dihydrate, sodium formate dihydrate, sodium formate dihydrate. Sodium formate is one of the simplest organic carboxylates. It is white crystals or powder with a slight Formic Acid odor. Slightly deliquescent and hygroscopic. Soluble in about 1.3 parts of water and glycerin, slightly soluble in ethanol and octanol, insoluble in ether. Its aqueous solution is alkaline. When heated, sodium formate decomposes into hydrogen and sodium oxalate, and then generates sodium carbonate. Sodium formate is mainly used in the production of insurance powder, oxalic acid and Formic ACID. In the leather industry, it is used as a camouflage acid in the chrome tanning process, used as a catalyst and a stable synthetic agent, and a reducing agent in the printing and dyeing industry. Sodium formate is harmless to the human body and has irritating effects on eyes, respiratory system and skin.

There have been many studies on the daily changes in photosynthesis, which have been classified into four types: regular curve type, flat type, variable power type, and noon reduction type. This study shows that Jinyang is a reduced type at noon, but the sunny days have a lower a-degree and longer duration than the nocturnal photosynthetic performance. Obviously it is due to strong sunshine and radiation (visible from the amount of accumulated light) at noon on sunny days, which results in overheating of the leaves, imbalance of water metabolism, stomatal closure, increased CO2 input resistance, and decreased efficiency of peroxidation, resulting in photosynthetic disturbance of the leaves. In addition, studies have found that there is also a midday decrease in C concentration. In summary, in the natural state, the high temperature associated with strong sunlight and the photosynthetic physiological barrier caused by the water deficit of p-b-tablet are combined with the higher degree of internal regulation, which is a further increase in the midday photosynthesis depression. the reason.
Computational calculations by the cumulation calculation software and related research comparisons have shown that the changes in the internal and external photosynthetic performance of the canopy are closely related to climatic conditions. Citrus is a kind of low-light-resistance plants with strong resistance to negative. Both light and high temperature can cause photosynthetic disturbance in leaves, which makes the sunny day outside the crown, the extra-canopy photosynthetic efficiency is lower than that inside the crown, and the cloudy outside is higher than the inside of the crown. This is because the leaves and leaves relatively reduce the radiation caused by strong light to the inner leaves of the crown.
