| 为了解桂林市沙糖橘产区的叶片营养元素的丰缺状况,并为桂林市沙糖橘的合理施肥提供一定的理论依据,于2017年调查分析了桂林市沙糖橘产区6个县60个果园叶片的氮(N)、磷(P)、钾(K)、钙(Ca)、镁(Mg)、硼(B)、铁(Fe)、锰(Mn)、铜(Cu)、锌(Zn)的含量状况。结果显示,桂林市沙糖橘叶片中N、P、K、Ca、Mg、B、Fe、Mn、Cu、Zn的平均含量分别为：(29.92±0.36)、(1.23±0.01)、(14.54±0.78)、(32.96±1.03)、(2.67±0.10) g.kg-1和(95.77±4.72)、(50.64±8.57)、(77.42±5.70)、(4.70±0.59)、(15.72±0.95)mg.kg-1.。其中,N和B含量普遍偏多,位于高量和过量水平的果园比例分别为43.33%和78.33%；P、K、Ca、Mg、Cu和Zn的含量普遍存在偏少现象,位于低量和缺乏水平的果园比例分别为38.33%、35.00%、40.00%、43.33%、65.00%和81.67%；Fe和Mn的含量适中的果园比例分别为65%和66.67%,均同时存在偏多或偏少的现象。桂林市沙糖橘产区树体营养元素失衡现象普遍存在,生产上应减少N和B肥的用量,重视补充P、K、Ca、Mg、Cu、Zn肥,合理施用Fe和Mn肥,以确保树体营养均衡,实现沙糖橘的优质丰产。 |

| In order to acquaint the nutritional status of Shatang tangerine in Guilin, the contents of leaf nutrients elements were analyzed, which could supply a theoretical reference for rational fertilization of Shatang tangerine in this region. In this experiment,we had investigated the nutrients condition in 6-month-old spring flush leaves of nonfruiting twigs from 60 Shatang tangerine orchards of 6 counties in Guilin in 2017. The results showed that, the average contents of nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium(Mg), Boron(B), iron (Fe), manganese (Mn), Cuprum (Cu) and zinc (Zn) in the leaves of Shatang tangerine orchard in guilin were (29.92±0.36)、(1.23±0.01)、(14.54±0.78)、(32.96±1.03)、(2.67±0.10) g.kg-1. and(95.77±4.72)、(50.64±8.57)、(77.42±5.70)、(4.70±0.59),(15.72±0.95) mg.kg-1.respectively The plethora of N and B were widely exist, and the proportion of orchards of N and B at high range and excess range was 43.33% and 78.33%, respectively.The lack of P, K, Ca, Mg, Cu and Zn were widely exist, and the proportion of orchards at low range and lack range were 38.33%, 35.00%, 40.00%, 43.33%, 65.00% and 81.67%, respectively. The proportion of orchards with moderate Fe and Mn contents were 65% and 66.67% respectively, both of which had the phenomenon of plethora or lack at the same time. In Guilin production areas, the imbalance of nutrient elements of Shatang tangerine trees is widespread. In production, the amounts of N and B fertilizer should be reduced, the supplement of P, K, Ca, Mg, Cu, Zn fertilizer should be emphasized, and the reasonable application of Fe and Mn fertilizer were requisite to ensure the balanced nutrition of trees and achieve high quality and high production. |
