摘  要：
【目的】为了解赣南脐橙园土壤有效锌含量状况,【方法】在赣南16县随机选取446个脐橙园,分析土壤农化样和背景样有效锌含量、pH值、有机质含量等。【结果】赣南脐橙园背景样和农化样土壤分别有80.78%和90.87%为酸性(pH<5.5),其中强酸性(pH<4.5)土壤分别占30%和44%;95.63%的背景样土壤和80.38%的农化样土壤有机质含量低于15 g.kg-1,农化样土壤有机质平均含量高于背景样土壤;背景样土壤有效锌平均含量仅为1.50 mg.kg-1,农化样为3.09 mg.kg-1;背景样和农化样有效锌不足(<2 mg.kg-1)的果园比例分别为77.29%和58.10%,只有10.92%背景样和16.35%农化样土壤有效锌含量达到适量(2~3 mg.kg-1)水平;土壤有效锌含量与土壤pH值和有机质均呈极显著正相关,有效锌与有效P、有效Cu的相关系数分别为0.420、0.502,呈极显著正相关。【结论】赣南脐橙园背景样土壤和农化样土壤均酸化严重、有机质和有效锌含量普遍偏低,应增施石灰、有机肥和锌肥矫治。

摘  要：
【Objective】This study was to understand the content of soil available zinc in navel orange orchards in southern Jiangxi province.【Method】Uncultivated soil samples(US) and cultivated soil samples(CS) collected from 446 orchards in 16 counties were analyzed.【Result】The results showed that soil acidification was obvious,80.78% US and 90.87% CS were acidic(pH<5.5),among which 30% of US and 40% of CS were highly acidic(pH<4.5).Both the average organic matter(OM) contents of US and CS were in the low range(<15 g.kg-1),but the average OM content of CS was higher than that of the US.The average available zinc(AZ) contents of the US and CS were 1.50 mg.kg-1 and 3.09 mg.kg-1,respectively.77.29% of US and 58.10% of CS were zinc-deficient(AZ <2 mg.kg-1),and only 10.92% of US and 16.35% of CS were zinc-suitable(2 to 3 mg.kg-1AZ).Both the soil pH values and OM contents showed highly significant positive correlation with the soil AZ contents.Both the soil available phosphorus and copper contents showed 0.420 and 0.502 significant positive correlation with the soil AZ contents,respectively.【Conclusion】Both the US and CS in navel orange orchards of southern Jiangxi province were highly acidifying and severe zinc-deficient,and the application of lime,organic fertilizer and alkaline zinc fertilizers was recommended.
