玉米是高产作物之一，但由于八五五农场地处山区、半山区，热量资源不足，年有效积温少，霜期早，给玉米后期收获存贮造成一定影响。为满足玉米大面积生产的需要，找出适应八五五农场不同区域栽培的玉米品种，我们对目前主栽的７个玉米品种（直播）进行了子粒脱水速度的测定，
Corn is one of the high-yielding crops. However, 855 farms are located in mountainous and semi-mountainous areas with insufficient heat resources. The annual effective accumulated temperature is low and the frost season is early, which will affect the harvesting and storage of maize in the later stage. In order to meet the needs of large-scale corn production and to identify maize varieties suitable for cultivation in different regions of 855 farms, we measured the rate of dehydration of seven maize varieties (direct seeding)
