摘    要:针对玉溪市设施栽培中存在的土壤盐分富集及养分不平衡问题,采用对比分析方法,将设施栽培土壤与露地栽培土壤配对,采集剖面土样和耕作层混合土样进行化学性状测试分析研究。结果表明,玉溪市设施栽培土壤pH值显著降低,盐分浓度、有机质、有效态N、P、K、S、Cu、Zn、Fe及交换态Mg显著提高,而交换Ca和有效Mn提高不明显;设施栽培土壤养分富集主要在0~10cm土层,且集中在0~2cm的表土层,其中以EC值、有效S、有效K及有效Mn在0~2cm表土层的相对富集量最多。

关 键 词:玉溪市  设施栽培  露地栽培  土壤化学性状

Abstract:Salt accumulation and nutrient unbalance exist in soils under protected cultivation in Yuxi City, Yunnan Province. Chemical properties were compared between the soils of protected and open fields by testing samples collected from paired soil profiles in the protected and open fields. Results showed that the pH value in the protected field was lower than in the open field, but and the salt concentration, organic matter, available N, P, K, S, Cu, Zn and Fe, and exchangeable Mg were higher, and exchangeable Ca and available Mn did not differ much between the pairs. Enriched nutrients were distributed mainly in the 0~10 cm layer and concentrated in 0~2 cm top surface, especially for EC value, available S, K and Mn.
Keywords:Yuxi City  Protected cultivation  Open cultivation  Chemical properties of soil
