Abstract:

To find out the key factors affecting the mechanical-harvesting quality of maize grain, and solve the problem of high moisture content of grain in harvesting period, the research on maize grain dehydration was summarized. It is suggested that in the process of mechanical-harvesting of maize grain, the key cultivation techniques should be breeding excellent varieties suitable for direct mechanical-harvesting, improving planting patterns, optimizing nutrient and water application methods, and developing efficient chemical control products to promote dehydration. Combining with maize production practice, suggestions are put forward to speed up the popularization of mechanical-harvesting of maize grains, such as speeding up the breeding of varieties of early maturity, fast dehydration and suitable for mechanical-harvesting; clarifying the factors and mechanisms that influence the dynamic state of mechanical-harvesting of grains in each ecological region; comprehensively using variety breeding, variety maturity stage configuration, delayed harvesting period and matching cultivation techniques. At the same time, it is necessary to develop light-simplified agricultural machinery equipment matching with agronomic measures, so as to enhance the application of mechanical-harvesting technology of maize grain and the overall competitiveness of maize industry.
