摘要
通过对青贮玉米密度与产量的关系研究表明:密度是影响青贮玉米产量的关键因素,青贮玉米生产最佳密度为 7.5 万~9 万株/hm2,高产密度不宜超过 9 万株/hm2。密度对青贮玉米秃尖长的影响最大,其次是千粒重。
The study indicated that the density was the key factor to output of ensiling maize. The best density of ensiling maize was 75 000~900 00/hm2. With a view to production, the density was no more than 900 00/hm2. Density had the most influences on length of bare top of ensiling maize, second was the weight of a thousand seeds.
