摘　　要：通过对100g、150g、200g、280g大小的红魔芋种芋材料开展密植试验,结果发现,150g的材料,当小区播种量为60粒时,膨大率最大(为5.7),投入产出比最高(为3.6),200g的材料,当小区播种量为36粒时,膨大率最大(为6.5),投入产出比最高(为3.8),而100g和280g材料的膨大率和投入产出比明显偏低。The experiment focus on the high density implantation of the Amorphophallus Bulbifer seed pieces in four different sizes, weighed in 100g, 150g, 200g and 280g. The result showed that with 60 seedlings in the zone, the 150g samples gain the biggest expansion rate and the highest input＆ output ratio, namely 5.7and 3.6; and 36 seedlings in the size of 200g hit the top in 6.Sand 3.8; as to the types of 100g and 280g, the two criterions are correspondily low.
