玉米巡天618适宜栽培密度初探

Preliminary Study of Appropriate Planting Density on Maize Xuntian 618

巡天618属于紧凑型玉米品种,为探索品种的适宜栽培密度,开展了5个不同密度的比较试验.结果表明：巡天618种植密度为5 000株/667 m2单产最高,达628.32kg/667m2,其次为5500株/667m2,单产601.37kg/667m2,与5000株/667m2单产差异不显著.说明巡天618适宜栽培密度为5000～5000株/667 m2.

Xuntian 618 is belong to compact corn, in order to explore the appropriate planting density, 5 different planting densities were applied in test. The results showed that the yield of Xuntian 618 at 5000 plants/66？m2 is the greatest, yielded 628. 32kg/667m2 , 5500 plants/667m2 is second, yielded 601.37kg/667m2 , hut the yield of 5000 plants/667m2 and 5500 plants/ 667m2 is not significantly. It＇s indicated that the appropriate planting density of Xuntian 618 is 5500--5500 plants/667m2.
