摘要: 通过不同种植密度对郑单22生长发育及产量影响的研究,郑单22单株叶面积和单株干物质积累量随密度增大而减小。群体叶面积系数和干物质积累量随密度增大而增加,达到一定种植密度后而下降,产量随密度加大而增加,结果表明,郑单22的适宜种植密度为45000~52500株/hm2。

Abstract: The influence of densisties on growth and yield of Zhengdan22 was studied. Leaf area per plant and dry matter accumulation per plant were dropped by densities increasing. Leaf area index and dry matter accumulation were increased by densities increasing and dropped by high densities. The yield was increased by densities increasing. The results showed that the suitable planting densisty of Zhengdan22 is 45000~52500 plants/hm2.
