为探讨玉米新品种浚单22获得高产的适宜种植密度,河南省浚县农业科学研究所对浚单22进行了5个处理的密度试验。试验结果表明:在5个试验处理的栽培密度中,以6.00万株/hm2产量最高,其次为6.75万株/hm2和5.25万株/hm2,适宜种植密度为5.25万～6.75万株/hm2。
In order to investigate the suitable planting density of new maize variety Xundan 22 for high yield, Xunxian 22 Agricultural Research Institute of Henan Province conducted a density test of 5 treatments. The results showed that among the five test treatments, the yield was 60,000 plants / hm2, followed by 67500 plants / hm2 and 52500 plants / hm2, and the suitable planting density was 52500 ~ 67500 plants / hm2.
