一般新收获的种子水分高达25%～45%。这么高水分的种子,呼吸强度大,放出的热量和水分多,种子易发热霉变,或者很快耗尽种子堆中的氧气而因厌氧呼吸产生的酒精致死,或者遇到零下低温受冻害而死亡。因此,必须及时将种子干燥,把其水分降到安全包装和安全贮藏的水分,以保持种子旺盛的发芽力和活力,提高种子质量,使种子能安全经过从收获到播种的贮藏期限。 General newly harvested seeds up to 25% to 45% moisture. Such a high moisture seeds, respiratory intensity, the release of more heat and moisture, the seeds are susceptible to moldy, or quickly run out of oxygen in the heap of seeds due to anaerobic respiration of alcohol to death, or encountered cold damage And death. Therefore, the seeds must be dried in time to reduce their moisture content to safe packaging and safe storage of moisture to maintain the vigor and vigor of the seeds and to improve the quality of seeds so that the seeds can pass the storage period from harvest to sowing safely.
