| 中文摘要: |
| 对云南省玉溪市4个代表性生态区的145个柑橘园春梢营养枝叶片矿质营养元素进行分析。结果表明,大量元素N、P、K的平均含量分别为3.03%、0.15%和1.32%,中量元素Ca、Mg、S的平均含量分别为4.46%、0.28%和0.30%,微量元素Fe、Mn、Zn、Cu、B的平均含量分别为145.94 mg.kg-1、102.07 mg.kg-1、16.79mg.kg-1、19.83 mg.kg-1、83.34 mg.kg-1。N和Fe以超标为主,超标果园分别为56.55% 和62.76%；P、Ca、S、Mn、B以适量为主,适量果园分别占56.55%、80.69%、83.44%、52.41%、69.65%；Zn、Mg以不足为主,不足果园分别为88.28%和67.59%；K和Cu超标、适宜和不足果园比例约各占1/3。玉溪产区柑橘树体营养存在明显丰缺失衡状况,N、Fe超标和Mg、Zn不足问题突出,其它元素不足和超标比例也较高,生产上要控制N肥,补施 Mg、Zn肥,增施有机肥。 |

| The contents of nutrient elements of citrus leaf were investigated and analyzed, and 145 leaf samples were collected from 145 orchards in 4 main producing areas in Yuxi City of Yunnan Province. The results showed that N, P , K, Ca, Mg, S , Fe, Mn, Zn, Cu and B were respectively in the average contents of 3.03%, 0.15%, 1.32%, 4.46%, 0.28%, 0.30%, 145.94 mg.kg-1, 102.07 mg.kg-1, 16.79 mg.kg-1, 19.83 mg.kg-1 and 83.34 mg.kg-1. N and Fe content in and above high volume were at the rate of 56.55%% and 62.76%; P、Ca、S、Mn and B content in appropriate range were at the rate of 56.55%、80.69%、83.44%、52.41% and 69.65%; Zn and Mg in and below low volume were at the rate of 88.28% and 67.59%; K and Cu excess, suitable and lack of orchard ratio accounted for about 1/ 3. The tested leaves suffered sharp nutrients imbalance. The problem of N, Fe excess and Zn, Mg deficiency is prominent. The lack of other nutrient elements and excess is also high. The production of N fertilizer, supplement Zn and Mg fertilizer, and organic application fertilizer. |
