| 摘 要： | 以5年生赣无系列油茶为研究对象,采用随机区组试验设计,设置施鸡粪、复合肥、生物有机肥、油茶专用肥,不施肥对照(cK)5个处理,分别对春梢进行调查并采叶片样品进行分析,通过研究比较4种肥料对赣无油茶春季叶片叶绿度sPAD值、叶片养分及干物质积累量差异,并分析它们之间的关系,以期为赣无油茶品系丰产栽培、科学施肥及氮素丰缺指标测定优化提供依据.结果表明:(1)氮对油茶春季叶片sPAD值贡献率最高,钾对叶片干物质积累贡献率最高;(2)施油荼专用肥叶片叶绿度SPAD值和叶片干物质含量最高;(3)不施肥叶片养分含钾量最高,施有机肥叶片含磷最高,施复合肥叶片含氮磷钾都最低.

| Abstract: | By the randomized block design,the effects of four fertilizers,chicken manure,compound fertilizer,bio-organic fertilizer,and specific camellia fertilizer,on the chlorophyll SPAD values,nutrients and dry matter accumulation in the leaves of five-year-old Jiangxi clone camellia plantations in this paper.The results showed that nitrogen had the greatest contribution to the chlorophyll SPAD value of the spring leaves and potassium had the greatest contribution to the dry matter of leaves.The average chlorophyll... |
