摘  要：
以板栗‘燕山早丰’(C.mollissima Yanshanzaofeng)为试验材料,对不同类型枝条叶片在雄花盛开期和幼果期矿质元素含量进行研究。结果表明,矿质元素在不同类型枝条中的分配存在特异性。板栗花期叶片中的N、K、Mn、Cu在结果枝叶片中含量最高,分别为1.60%、0.57%、776.66 mg·kg-1、10.45 mg·kg-1;P含量在雄花枝中最高,为0.14%;Ca、Mg、B则在营养枝中含量最高,分别为1.17%、0.29%、102.37 mg·kg-1。板栗幼果期叶片中,P、Ca、Fe、Mn含量为结果枝>营养枝,N、Mg和B含量为营养枝>结果枝,K、Cu在营养枝和结果枝中的含量基本相同。板栗结果枝叶片在花期对N、K、Cu的需求量大,Mn和Fe在结果枝中的含量幼果期较花期提高18.89%和33.68%,在营养枝中提高10.79%和25.93%,P、Mg、B和Ca含量在两个时期则无显著差异。因此,花期应适当补充N、K和Cu肥,幼果期补充P、Mg、B和Ca肥。

摘  要：
This research explored the distribution property of the mineral elements in Castanea mollissima Yanshanzaofeng in different types of shoots during the staminate flowering and young fruit stage. The results showed that distribution of mineral elements content specificity in different types of shoots. The content of N, K, Mn and Cu was the highest in leaves of fruit-bearing shoot, 1.60%, 0.57%, 776.66 mg· kg-1, 10.45 mg· kg-1, respectively; the content of P was 0.14% in staminate shoot and the content of Ca, Mg and B was the highest in vegetative shoot 1.17%, 0.29%, 102.37 mg· kg-1, respectively during flowering period. The content of P, Ca, Fe, Mn was the highest in leaves of fruit-bearing shoot, the content of N, Mg and B was the highest in leaves of vegetative shoot and the content of K, Cu in leaves of vegetative shoot was the same as fruit-bearing shoot during young fruit period. N, K, Cu was in great demand in leaves of fruit-bearing shootduring flowering period, the content of Mn and Fe increased 18.89% and 33.68% in leaves of fruit-bearing shoot during young fruit period than flowering peirod and increased 10.79% and 25.93% in leaves of vegetative shoot, the content of P, Mg, B and Ca there were no significant differences between the two periods. In all, raising N, K and Cu application properly during flowering period and raising P, Mg, B and Ca application during young fruit period.
