| 摘 要： | 通过茎部施用不同浓度的锌肥来考察其对金桔叶相对生长率、新梢相对生长率、叶绿素含量、产量、总酸度、总糖含量、Vc含量以及锌在果实中的积累的影响。结果表明，茎部施肥对植株的生长有明显促进作用，果实中糖酸比增大，叶绿素含量和Vc含量增加，同时锌在果实中有一定的富集；茎部施用锌肥浓度不同，其影响也不同，茎部施用硫酸锌效果优于根部施用硫酸锌，用灰色关联分析法进行分析，综合评判结果与试验结果相一致。

| Abstract: | The effects of zinc injection with various Zn concentrations in trunk of kumquat on the relative growth rate of leaves and tips, chlorophyll content, output, general acid degree, general sugar content, Vc content and zinc accumulation in fruits were observed. The results showed that the trunk injection of zinc had an apparent promoting effect on plants growth. It improves the sugar acid ratio of fruits and raises the chlorophyll and Vc contents. The effects on the growth of kumquat vary with the concentration of injected ZnSO 4, and the effect of ZnSO 4 injection in trunk is superior to that of ZnSO 4 fertilizing on root. The results of the synthetical judgment by the method of grey incidence analysis coincide with above investigations. |
