摘　　要：为了解谷子地上干物质量的分配情况,以4个品种为研究对象,调查每个品种各器官干物质量的分配情况。结果表明,4个谷子品种中,长生13植株最矮;长农35号植株最高并且地上干物质量最大。4个品种的地上干物质量叶鞘比例均是由大变小;茎比例的变化均是先变大后又减小;3个品种的叶比例变化一致。完熟期长生13的穗比例最大,表明虽然长生13植株最矮,但较适合机械化收获并且其经济转化率较高。In order to understand the distribution of dry matter quantity on the millet,we used four varieties as research objects to investigate the distribution of dry matter quantity of each organ.The results showed that the Changsheng 13 plants were the shortest among the 4 millet varieties;and Changnong 35 has the highest plant and the highest dry matter on the ground.The ratio of the leaf sheath of the aboveground dry matter of all varieties changed from large to small.The change in stem ratio firstly increased and then decreased.The change of stem ratio firstly increased and then decreased for all varieties.And the change in leaf ratio was consistent with three varieties.In the mature period,the ratio of the ear of Changsheng 13 was the largest,which indicated that although Changsheng 13 plant was the shortest,it was more suitable for mechanized harvesting and its economic conversion rate was higher.
