An In Situ Method for the Study of Maize Kernel Dehydration

Abstract

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.

Description

technical field [0001] The invention relates to a method for measuring the dehydration of corn grains, in particular to an in-situ determination method for studying the dehydration of corn grains. Background technique [0002] Corn is the largest food crop in my country and has an important strategic position in ensuring food security in China. In recent years, the country has implemented a series of agricultural science and technology actions, and the record of high corn yield has been continuously refreshed and the yield has been continuously increased. However, with the acceleration of rural urbanization in my country, a large number of agricultural laborers are moving to cities, the corn production mode and labor force structure are undergoing great changes, the speed of large-scale production is accelerating, and new challenges have emerged for the continuous increase of corn production and efficiency. On the one hand, there is a lack of high-density, high-yield variet...

Problems solved by technology

In terms of research methods, regular sampling (in vitro observation) is used to detect water changes. On the one hand, this method cannot rule out the interference of some influencing factors. On the other hand, the operation process of this method is poor in standardization, and the experimental error of repeatability measurement is large.
