Rapeseed is one of the most important sources of edible vegetable oil and forage protein in China. The processed product of rapeseed, rapeseed oil, has been increasing in consumption of edible vegetable oil in China in recent years. Therefore, in order to ensure the safe supply of edible oil, the country will develop Rape production is the focus of agricultural work. In the rapeseed breeding work, the leaf area measurement is an important measurement item. The leaf area detector can accurately and quickly measure the leaf area of ​​rapeseed, and guide the improvement of crop light energy utilization rate, thereby improving the yield of rapeseed planting. And quality. Leaves are important sites for photosynthesis and transpiration of plants, and are important organs for the production of nutrients. Leaf area is an important factor determining the amount of photosynthesis products. The size of leaf area determines the size of photosynthetically active radiation, reflecting the plant Adaptation strategies such as geographical distribution and nutrient conditions are an important indicator of crop photosynthetic performance. At the same time, leaf area is also an important physiological and morphological indicator affecting plant growth, fruit development and quality. Therefore, the determination, research and guidance improvement of leaf area size are of great significance for the breeding and cultivation of rapeseed and other crops. At present, the methods for measuring leaf area mainly include square counting method, drawing paper weighing method, punching method, leaf area instrument method, image processing method and coefficient regression method, etc., after comparison of actual application, it is found that leaf area detection is used. Instrumental measurement is a method of measurement that is highly recommended by everyone in breeding research. Because the leaf area detector has the advantages of convenient carrying, simple operation, accuracy and high efficiency, it is very suitable for popularization and application. Through the successful application of the leaf area detector in the determination of rapeseed leaf area, the instrument will be further recognized by agricultural research and breeding experts, and thus more widely used in high-efficiency breeding and physiological research, for the majority of agricultural work. It saves a lot of time and improves the efficiency and effectiveness of scientific research.
