摘要
黑河地区玉米品种较杂、较乱,为指导当地玉米生产,在黑龙江省黑河市通过连续3年的品种筛选试验,选出综合性状最好的6个早熟品种为试验材料进行耐密性试验。结果表明:德美亚1号、德美亚2号、克单14适宜种植密度9万株.hm-2;边单3号、利合16、垦单16适宜种植密度7.5万株.hm-2。
Maize varieties cultivated in Heihe area was complex and chaos, in order to guide local maize production, variety screening test was conducted in Heihe city for 3 consecutive years. 6 comprehensive characters were selected out with the best early-maturing varieties to conduct the experiment of varieties resistant to density. The results showed that Demeiya 1,Demeiya 2, Kedan 14 were suitable for planting under the density of 90 000 plants·hm^-2 , Biandan 3, Lihe 16 and Kendan 16 were suitable for planting under the density of 75 000 plants·hm^-2.
