The handheld chlorophyll meter helps us to quickly measure the total leaf area of ​​the whole plant. The leaf is the producer of photosynthetic products. It is an important vegetative organ of fruit trees. The size of the leaf area directly affects the various life activities of the plant, and it is related to the level of fruit tree production. Good or bad, accurate measurement of leaf area can help us quickly understand the relationship between leaf development and leaf area growth, leaf photosynthesis and moisture, leaf and fruit ratio, as well as formulating reasonable cultivation methods, orthopedics pruning and fertilization schemes. The guiding significance. There are many ways to measure the leaf area, but most of the methods of measurement will destroy the plant, affecting the normal growth and development of the plant and the formation of biomass. Here's a leaf area measurement method that uses the handheld leaf area. Instrument to make measurements.
The leaf area of ​​the kiwifruit was measured by using a hand-held leaf area meter, and the length of the leaf, the width of the leaf, and the length-width product of the leaf were calculated by him. The handheld leaf area meter has a function: with a computer interface, data viewing is no longer confined to the observation on the host, and can be uploaded to the computer for further viewing, and a data analysis software corresponding to the instrument at the same time, The software can be printed and converted into EXESEL format. Use Excel to perform regression analysis on the measured data. Fitting results show that the best relationship between leaf area and leaf length is a power function. By doing so, the initial regression equation can be used to perform further calculations through the regression equation method. The leaf area will be smaller, and the error will be smaller. The linear regression equation of leaf area and length-width product, the linear regression equation of leaf area and leaf width, and the linear regression equation of leaf area and leaf length were used to compare the results to obtain the most accurate measurement method. The exact method of kiwifruit was leaf Area and length-width product linear regression equation. By using it for conversion, the total leaf area of ​​the plant can be obtained, saving a lot of time.
Chlorophyll meter is also an instrument for leaf detection. It only detects the chlorophyll content in the leaf. The detection of chlorophyll content can help us understand the nitrogen content in the plant, and to a certain extent can help us reduce it. The amount of nitrogen fertilizer applied does not reduce crop yield.
