北方地区玉米收获后的水分多在25％～30％左右,脱粒时间一般在11月份。这样高水分的玉米必须进行干燥处理,否则不易贮藏或销售。通常的干燥方法有以下几种: 一、玉米果穗仓贮干燥玉米果穗收获后,由于水分含量大,籽粒难脱且破碎严重,所以北方地区普遍地采用果穗仓贮干燥。这种玉米干燥方法的优点是利用自然风和太阳能,节能效果明显,干燥质量好,成本低。但是,这种玉米干燥方式需要的仓容较大(果穗的比容是谷粒比容的1倍以 Harvesting of corn in the north after the water more than 25% to 30%, threshing time is generally in November. Such high moisture corn must be dried, or not easy to store or sell. The usual methods of drying are the following: First, corn ear storage and drying Corn ear harvest, due to the large amount of water, hard to break the grain and broken serious, so the northern region commonly used fruit storage and drying. The advantages of this method of drying corn is the use of natural wind and solar energy, energy-saving effect is obvious, dry and good quality, low cost. However, this corn drying method requires a larger storage capacity (the specific volume of the ear is twice the specific volume of the grain
