An in-situ measurement method for corn kernel dehydration research. This method is to select representative ears for in-situ treatment of kernels during the corn filling stage in the field, and apply a quick-drying chemical liquid that has no effect on the development of corn kernels in different ways. Coating, and taking the unsmeared ear homotopic grain as a control, after a period of time, samples were taken to observe the change of grain moisture content, so as to obtain information such as grain dehydration rate, period, and route. The in-situ determination method for corn grain dehydration research can not only reduce the in-situ observation method in the process of corn grain dehydration determination research, but also reduce the in-situ treatment operations such as whole ears, smearing and coating, in-situ treatment of grains, bract leaf restoration, and bundling. Existing measurement errors can reduce external interference, which is beneficial to the later research on the determination of corn grain moisture content dynamics, etc., and has good operability and universality. The experimental results are repeatable, and it is easy to form a fixed corn grain dehydration measurement operation. Specification and experimental procedures.
