Leaf area meter is a new method for determining leaf area of ​​cucumber

November 14, 2024

Cucumber is a kind of vegetable that we are most familiar with, and it is also considered to be fruit, so it is a kind of agricultural product that we are more familiar with. The cultivation of cucumbers is very extensive. In recent years, in order to improve the yield and quality of cucumbers, the breeders have begun to use scientific instruments such as leaf area meters for analysis and research, providing new ideas and means for information acquisition in all aspects of cucumber.
The leaf area meter is a special instrument for determining the leaf area of ​​a plant, and the reason why the leaf area of ​​the plant is determined depends on the importance of the leaf for plant growth. We know that the leaves are the main organs of plants for photosynthesis and transpiration, so their development status and the size of the leaf area will have important applications for plant growth, germination, and resistance to the formation of yield, so the size of the leaf area is physiological and biochemical. The research on genetic breeding and cultivation is an important part of the research process. Therefore, the determination of leaf area has gradually become the norm. At this time, we need a method that can measure the leaf area accurately, and the application of the leaf area meter, Just filled the vacancy in this area.
Previous methods for determining the leaf area of ​​cucumbers and other plants include grid method, paper weighing method, fresh weight method, coefficient method, etc. However, these methods often have problems such as low measurement efficiency, complicated method, and low accuracy, and now agriculture Research has very strict requirements on data in this area, so these methods have such a big limitation. With the development of science and technology, the leaf area meter has become a new method for determining the leaf area of ​​cucumber. Using it to measure the leaf area of ​​cucumber, it has the advantages of high accuracy, simple operation, good instrument stability, portability, and suitable for field measurement. Therefore, by comparing the advantages and disadvantages of various methods, it is generally believed that the leaf area meter is a reliable method for measuring the leaf area of ​​cucumbers, and can serve scientific research work.
