摘　　要：为了探明沪玉糯2号、沪玉糯3号的最佳种植密度,开展了密度因素对糯玉米品种沪玉糯2号、沪玉糯3号产量、叶面积及干物质积累的影响试验。结果表明:沪玉糯2号、沪玉糯3号的产量均在密度为4 000株/667m2最高,叶面积系数大,干物质积累多,穗粒数多。其次为3 500株/667m2,4 500株/667m2时最低。说明沪玉糯2号、沪玉糯3号在安顺市以推广4000株/667m2为宜。In order to explore the best planting density of Huyunuo 2 and Huyunuo 3,effects of different planting density on yield,LAI and dry matter of Huyunuo 2 and Huyunuo 3.The results showed that the best planting density for this two varieties is 4000plants/667m2,LAI of two varieties is big,dry matter and number of grains is more than other treatments.The second yield of this two varieties is 3500plants/667m2 and the lowest yield is 4500plants/667m2.It＇s indicated that the appropriate planting density of Huyumuo 2 and Huyunuo 3is 4000plants/667m2 in Anshun.
