杂交玉米种子的生产特点是:技术性强,周期长,受环境条件制约较大。防患于未然,弥补自然灾害造成的缺种,才能保证农业生产发展的需要。目前,在种子公司普遍没有低温仓库的条件下,高温多湿容易导致种子老化,用普通仓库贮藏后备的玉米单交种发芽势、发芽率、生长潜势和生产潜力有没有变化,值得研究和探讨。
Hybrid corn seed production characteristics are: strong technical, long cycle, subject to greater environmental conditions. Take preventive measures to make up for the lack of natural disasters in order to ensure the development of agricultural production needs. At present, under the condition that seed companies generally do not have low-temperature warehouses, high temperature and humidity will easily lead to the aging of seeds. There is no change in the germination potential, germination rate, growth potential and production potential of single hybrid corn seeds reserved in common warehouses, which deserves research and discussion .
