    摘要:

    昆明地区蔬菜、花卉种植以设施栽培为主,本文对不同棚龄的大棚设施土壤pH、全N、P、K、碱解N、速效K、有效P、交换性Ca、Mg等指标进行测定分析,结果表明:随棚龄年限的增长,耕层土壤pH值、有机质和土壤交换性Ca、Mg含量有降低的趋势,但无论是露地还是盖棚土壤有机质(52.8 g/kg)都较20世纪80年代中期有较大幅度提高;耕层土壤和深层土壤,全N、有效N含量呈持续上升趋势。耕层土壤中,土壤速效K和速效P呈现明显的富集。

    Abstract:

    The soil chemical properties under different protectorate cultural time and different soil layer in Chenggong County, Yunnan Province, were studied. The result showed that soil organic matter, exchangeable Ca and Mg with longer protectorate cultural time was lower, the soil pH under different protectorate cultural time had also become lower than that in opening soils slightly. While the content of available N, P, K had accumulated higher with longer protectorate cultural than that of opening soils. Total N, P, K content have slight accumulated as its available forms. What's more, whether protectorate culture or not soil organic matter content was higher than that in 1984.
