Because the leaf is the main source of crop organic matter, and it directly determines the amount of light energy and the absorption of water and nutrients, but also the master of organic synthesis. Therefore, the development status of leaves and the size of leaf area have a great influence on the growth and development of crops, stress resistance, and yield formation. It is a content that must be taken into consideration in the aspects of physiological and biochemical, genetic breeding, crop cultivation, etc., as well as crop growth and development, Important indicators such as yield formation and variety characteristics. Larger leaf area means that the more light energy intercepted by plants, the interception of light energy, to a certain extent, allows plants to have more resistance to nature's adverse environment.
Insufficient water resources is a common problem in countries all over the world. Instead, the use of handheld leaf area meters to control the leaf area of ​​plants can reduce the waste of water resources. The main reason for this approach is that the leaf area also determines transpiration. The strengths and weaknesses, in the current situation of scarce water resources, the adjustment of leaf area to improve the water use efficiency of green plants has become a reasonable and effective way to save water.
Leaf area fertilizer, this time it is well-known, from this time it can be seen that the blade has a certain absorption, will absorb the nutrients applied to the blade and use.
Through the use of hand-held leaf area meters for the measurement of leaf areas for various types of crops, it will be helpful for the proper close planting of crops, scientific fertilization, increased utilization of chemical fertilizers and soil moisture, and judgment of worm disease disasters, while leaf area The measurement using the handheld leaf area meter will be more accurate than using the conventional method.
Plant leaf area measurement in agriculture
The location of plant leaf area measurements in agriculture The leaves of plants are an important factor that connects plants with the outside world. Many things are reflected from the tender leaves. The size of leaf area is an important indicator that determines the photosynthesis of plants, and it is the product that affects photosynthetic products. The important characteristics of the crop, therefore, have a direct impact on the yield of crops. In agriculture, hand-held leaf area meters are used to determine the size of the leaf area in order to determine the crop yield.
