玉米种子的含水量,是种子质量的一个重要指标。刚收入的玉米种子,一般含水量较高(30%左右),在没有烘干设备的地方,如不进行充分的自然晾晒,种子水分很难降到越冬贮藏的安全限度(15%),特别是低温、早霜年份过晚收获的种子危险性更大。可根据自己的实际条件选择不同的晾晒方法,使玉米种子安全越冬。 1.高茬晾晒:这种晾晒法是目前生产上使用最普遍、最安全、又经济廉价的一种方法,在秋季连续低温多雨等恶劣气候条件下此法效果更好。高茬晾晒的具体做法:收获时首先把父本运出、然后把玉米秸割 The moisture content of corn seeds is an important indicator of seed quality. Freshly harvested corn seeds generally have a high water content (around 30%). In places where there is no drying equipment, seed moisture is hard to drop to the safe limit of overwintering storage (15%), especially if it is not fully air-dried It is cold, and the seeds harvested at early frost years are more dangerous. According to their actual conditions to choose different drying methods, so that the safety of winter corn seeds. 1.
