Nondestructive testing method for hollowness degree of melon hypocotyl and application of nondestructive testing method

The invention discloses a nondestructive testing method for hollowness degree of melon hypocotyl and application of the nondestructive testing method, and belongs to the technical field of crop breeding and planting. According to the nondestructive testing method, ultrasonic waves are used for conducting nondestructive testing on the hollow degree of the hypocotyl in the seedling stage, the hollow degree can be quantified through wavelength feedback in combination with stem diameter measurement, the method has the advantage of being high in precision, and the hollow degree of the hypocotyl can be quantified through nondestructive testing on the hollow degree of the hypocotyl in combination with the factors such as the seedling raising environment and the seedling raising time. According to the method, variety-targeted hollow conditions can be obtained, and then the variety or a seedling raising technology matched with the variety is obtained, so that hypocotyl hollowness is avoided or reduced, the grafting su
