种子含水量偏高,气候寒冷是造成北方地区玉米种子冻害、发芽率降低的主要原因,2002年冬季,这个问题显得尤为突出。为此,因地制宜,采取适宜的种子晾晒技术,对于确保种子质量,保证种子生产企业增效,制种农户增收均具有十分重要的意义。经过多年的实践,现将玉米种子晾晒技术总结如下: 1 田间站秆扒皮晾晒站秆扒皮时期在辽宁省为9月中旬。当母本果穗进入蜡熟后期,从果穗顶部自上而下将苞叶剥开,要一剥到底,不能留在子粒上面。
The high water content of seeds and the cold climate are the main causes of frost damage and germination rate of maize seeds in the northern part of China. In the winter of 2002, the problem was particularly prominent. To this end, according to local conditions, to take appropriate technology of seed drying, for ensuring the quality of seeds, seed production enterprises to ensure efficiency, increase seed production farmers are of great significance. After many years of practice, now corn seed drying technology is summarized as follows: 1 field station stalks Peel drying station stalks peeling period in Liaoning Province in mid-September. When the female parent ear into the late wax ripening, from the top of the ear top to bottom bracts peeled, to peel in the end, can not stay in the grain above.
