| 摘 要： | 本文通过对云南不同区域、不同大棚种植年限的设施土壤养分累积特征进行研究。结果表明：云南设施土壤耕层养分累积现状为全氮含量范围为0.99-4.15 g•kg-1；全磷含量范围为0.53-5.64 g•kg-1；全钾含量范围为1.15-56.49 g•kg-1；碱解氮含量范围为69.0-368.9 mg•kg-1；速效磷含量范围为6.95-214.9 mg•kg-1；速效钾含量范围为72.8-2654.4 mg•kg-1。随着设施土壤种植年限的延长全氮、全磷、碱解氮、速效磷、速效钾呈现上升的趋势，全钾则有升有降；随着土层深度加深，土壤各养分含量减少，土壤表层呈现养分富集现象。

| Abstract: | Cultivation in Greenhouse has become one important cropping system in Yunnan province. The accumulation of salt caused by different fertilization may affect the soil ecosystem in Greenhouse. This paper investigated the salt contents of soil surface horizon in Greenhouse soil from six major areas in Yunnan Province. The results are: In the top layer of Yunnan greenhouse soil, the soil total N, P and K contents were 0.99-4.15 g&;#8226;kg-1, 0.53-5.64 g&;#8226;kg-1, 1.15-56.49 g&;#8226;kg-1 respectively. The available N, P, K contents were 69.0-368.9 mg&;#8226;kg-1, 6.95-214.9 mg&;#8226;kg-1, 72.8-2654.4 mg&;#8226;kg-1 respectively. With the increasing of the greenhouse ages, total N, total P, available N, available P and available K of soil appeared increased. Soil nutrient accumulated in the top layer, the contents of soil nutrient decreased gradually with the soil layer deepening． |
