研究了高温闷棚下，不同填充物和不同灌溉量处理对土壤理化性状的影响。试验结果表明，与单施有机肥或石灰氮相比，有机肥和石灰氮复合添加能明显提高土壤的pH值；增施有机肥提高土壤的EC值；增加土壤湿度能明显降低土壤的EC值；高温闷棚下单施有机肥能明显增加土壤有机质含量，而单施石灰氮会导致土壤有机质含量下降；单施有机肥可导致土壤NO3--N含量明显增加，而单施石灰氮却导致土壤NO3--N含量明显降低，有机肥和石灰氮复合添加能明显促进NH4+-N含量增加，增加土壤湿度使土壤NH4+-N含量增加、NO3--N含量减少；单施有机肥或石灰氮均可增加速效磷和速效钾含量，两者配施情况下土壤速效磷和速效钾含量增加幅度更大，土壤湿度越大速效磷的含量越高，土壤湿度过大则会降低钾的有效性。

This experiment researched the effects of different fertilizer and irrigation amount treatments on soil physical and chemical properties on the condition of closed greenhouse at high temperature. The results showed that, compared with the treatments single addition of organic fertilizer or lime nitrogen, the combined addition of organic fertilizer and lime nitrogen could obviously improve soil pH value, and the addition of organic fertilizer increased soil EC value, while the increase of soil humidity could obviously reduce soil EC value. In the closed greenhouse at high temperature, the single addition of organic fertilizer could obviously increase the contents of organic matter and NO3--N in soil, on the contrary, the single addition of lime nitrogen reduced the contents of organic matter and NO3--N obviously in soil. The combined addition of organic fertilizer and lime nitrogen could promote the content increase of NH4+-N in soil, and increasing soil humidity could increase NH4+-N content but reduce NO3--N content in soil. The contents of available phosphorus and potassium were increased in soil when single organic fertilizer or lime nitrogen was added, and the increasing range was larger especially when both two fertilizers were added in soil. The increase of soil humidity caused the content increase of available phosphorus in soil, while larger irrigation amounts reduced the availability of potassium in soil.
