摘要
2012年在榆次区和五寨县对玉米新品种晋单84号进行了密度试验,以明确其最佳密度范围,为推广应用提供理论依据。结果表明,在不同密度下,晋单84号的5个性状表现不同;在7.25万株/hm2时,晋单84号的产量、株高、穗位高和黑粉病发病率4个性状均表现最高,在榆次区和五寨县的产量分别达到12066.35,11230.77kg/hm2;榆次区晋单84号未出现倒折,但黑粉病发病率显著高于五寨县。
To make clear the best density range of new early maturing maize Jindan 84, the density test was made in Yuci prefecture and Wuzhai county in 2012 to provide theoretical basis for the popularization. The results showed that the five traits＇s performance of Jindan 84 were different under different densities. Under the density of 72 500 plants/hm2, the yield, plant height, ear height and incidence of smut of Jindan 84 were the highest, and the yields in Yuci and Wuzhai were 12 066.35 kg/hm2 and 11 230.77 kg/hm2 respectively. The falling-off did appear in Yuci. The smut incidence in Yuci was significantly higher than that in Wuzhai county.
