| 摘 要： | 以6年树龄红枣树为试材,采用刨根、分解取样的方法,研究了年周期内各器官的生物量、氮、磷、钾含量和氮磷钾累积量变化动态.结果表明,红枣各器官中干物质、氮、磷、钾的积累均随生育期的推进呈增长趋势,从果实膨大期到果实成熟期均有一个急剧的上升过程.红枣树单株生物量年增加3908.5 g,氮、磷和钾年总吸收积累量分别为70.5、...

| Abstract: | The yearly biomass,contents of nitrogen,phosphorus and potassium and their accumulation at different parts of Chinese jujube(Zizvphus jujube) tree were studied.The trees are cultivated about 6 years under field condition.The results show that the cumulative amounts of dry matter,N,P and K in all organs are increased with the growth and development of Chinese jujube,especially from the fruit expanding stage to harvest stage.The yearly biomass increase is about 3908.5 g/plant.Total nitrogen,phosphorus and pot... |
