众所周知,玉米高产的基础是使用高质量、高活力的杂交一代种。但玉米单交种发芽率与出苗率的剪刀差近年愈来愈表现明显,很大程度上影响着农业生产的丰收,引起了国内外有关专家的关注。问题从穗粒腐病、霉变、黑根等现象反应出来。从适时收获及时脱水、脱粒晾晒、地膜覆盖等环节做好工作,种子发芽势将会显著提高。 As we all know, the basis of high yield of corn is the use of high quality, high vigor hybrid generation. However, the scissors difference between the germination percentage and the emergence rate of corn single cross was more and more obvious in recent years, which greatly affected the harvest of agricultural production and attracted the attention of relevant experts at home and abroad. Problems from the panicle rot, mildew, black root and other phenomena react. Timely harvest from the timely dehydration, threshing drying, mulching and other aspects of the work well, the seed germination potential will be significantly increased.
