机械化收获对玉米种子发芽率的影响研究

A Study on the Effect of Mechanized Harvesting of Corn Seeds on Germination Rate

在玉米制种生产过程中,机械化收获时如果操作不当将会对种子造成机械损伤,从而影响玉米种子的发芽率,不利于提高玉米生产的产量和品质,特别是会对高产量玉米品种生产性能的发挥产生不利影响。结合实际工作经验,探讨了玉米种子机械化收获对发芽率的影响的因素,提出了相应的解决对策,以减少玉米种子机械化收获的损伤,促进玉米产业的健康发展。

In the production process of corn seed,improper mechanized harvesting operation could cause mechanical dam-age of corn seeds which had the results of low germination rate and negative effects for increment of corn yield and quality,es-pecially could have unsatisfied results for performance of high yield corn production.Combined with practical working expe-riences,the impact factors of mechanized harvesting of corn seeds on germination rat were analyzed,and relevant countermeasures were proposed in order to reduce the mechanical damage of corn seeds during mechanized harvesting and to promote healthy development of corn production industry.
