Photosynthesis, transpiration and respiration of plants are all dependent on the growth and development of the leaves of the plant. Its state is directly related to the growth and development of the plant, especially the size of the anterior leaf area of ​​the strawberry has a great influence on the yield and fruit quality of the plant. For this purpose, a simple method for determining the leaf area of ​​strawberries was found. Will provide the basis for strawberry production management methods. The current modernization method is to use photoelectron leaf area meter, but most production units are limited by the conditions of capital and equipment. Not yet achieved. The leaf area meter can effectively measure and analyze the leaf area of ​​the plant, and the result is very accurate and reliable.
The use of transparent grid method or weighing method to measure the leaf area often requires the removal of the leaves! Inconvenient on-site operation! It is also not conducive to continuous dynamic observation. * The method for the simple determination of leaf area of ​​other fruit tree species has been reported. The method of simple determination of strawberry leaf area has not yet seen the data. For this purpose, using the transparent grid method as a control, compare leaf length and leaf area regression methods such as leaf length and leaf area regression method, leaf length and leaf area regression method, and leaf area determination method. method.
The experiment was set up in the sunlight greenhouse of Henan Hi-tech Park of Science and Technology. The soil was sandy loam, and all the leaflets of the three compound leaves were determined. Each variety was not less than 30 leaves. You can also use the leaf area meter to measure, or cover the strawberry leaves with a transparent checkered plate with 8>75F98>75F squares, and count the number of squares occupied by the leaves, and specify the area occupied by the leaves. Calculate the area above by B! The value less than Bd! is ignored. * The number of squares occupied by the leaf is multiplied by the area of ​​each square. C8>75F98>75F<8>!75FJ is the leaf area* of the leaflet. The leaf area determined by the grid method is used as a control for other assay methods.
