通过在第六师共青团农场开展6 000株/667 m~2、7 000株/667 m~2、8 000株/667 m~2、9 000株/667 m~2 4种不同密度玉米种植试验,结果表明:供试玉米品种中,郑单958在种植密度为7 000株/667 m~2时,单产可达1 267.31kg/667 m~2,位居第1;而玉米品种德美亚2号、克玉16、先玉38P05适宜的种植密度分别为7 000株/667 m~2、6 000株/667 m~2、7 000株/667 m~2。
By planting 6,000 plants / 667 m -2,7 000 plants / 667 m -2,8,000 plants / 667 m -2,900 plants / 667 m -2 24 maize plants of different densities in the sixth division of the Communist Youth League farm The results showed that the yield of Zhengdan958 reached 1 267.31kg / 667 m ~ 2 at the planting density of 7 000 plants / 667 m ~ 2, which was the highest among the maize varieties tested. The maize variety Demeiya 2 The suitable planting densities of Jade 16 and Jade Jade 38P05 were 7 000 plants / 667 m -2 2,600 plants / 667 m -2,7 000 plants / 667 m 2, respectively.
