以2015年从我国黄淮海、华北、西南三区收集到的206份市售大田常规玉米品种种子为材料,统计分析其销售方式、包装方式、包衣情况、包装袋标识等信息,测定其发芽势、发芽率、合格率等指标,并比较2013—2015年三区市售种子质量。结果表明,2015年的206份样品中,袋装的比例为96.1%,粒装的比例为31.5%,包衣的比例为97.6%;标识纯度、净度、水分、发芽率、粒数、重量和粒型的分别有3、2、4、7、20、9、21种。检测发芽率达到国标发芽率(85%)的比例为98.5%,合格率为94.7%。与2013、2014年相比,2015年三区玉米种子质量整体水平呈上升趋势。
In this study, 206 varieties of common maize seeds from market were collected from Huanghuaihai, North China and Southwest China in 2015, and their sales methods, packaging methods, coating conditions and packaging bags were statistically analyzed to determine their germination Potential, germination rate, pass rate and other indicators, and compared 2013-2015 three districts of commercially available seed quality. The results showed that among the 206 samples in 2015, the percentage of bagging was 96.1%, the percentage of grain filling was 31.5% and the percentage of coating was 97.6%; the purity, clarity, water content, germination rate, grain number and weight And grain type respectively 3,2,4,7,20,9,21 species. Detection of germination rate reached the national standard germination rate (85%) was 98.5%, with a pass rate of 94.7%. Compared with 2013 and 2014, the overall quality of seed quality in three districts in 2015 showed an upward trend.
