用矿物燃料作为能源人工干燥玉米籽粒是昂贵的,但在秋季冷凉湿润的温带这又常常是必要的。在一些地区,如新西兰,可在晚秋和冬季把玉米长时间留在田间自然干燥,从而降低费用,可是如果秋天和冬天田间条件变得更加湿润时,将导致收获困难并因倒伏而造成损失。高产、脱水快的玉米杂交种是最理想的。在新西兰,收获玉米的最佳时期是当果穗 Artificially drying corn kernels with fossil fuels as an energy source is expensive, but it is often necessary to cool and wet the temperate zone in the fall. In some areas, such as New Zealand, corn can be naturally dried in the late autumn and winter for prolonged periods of time to reduce costs, but harvesting difficulties and loss of lodging can result if autumn and winter field conditions become more moist.
