摘要
通过合玉19玉米新品种不同密度、不同追氮量对产量反应的研究,认为合玉19玉米新品种栽培密度在4.5万株/hm2左右,追氮量375 kg/hm2时,产量较高。
Study on the response to plant density and the additional nitrogen amount of Heyu 19 was discussed and analyzed. The reasonable plant density and the additional nitrogen amount were determined, they were 45 000 kg/hm^2 and 375 kg/hm^2, respectively. After taking those measures, the high yield would be attained.
