Abstract: In order to investigate the nutrient available of manure under different soil temperature condition and nutrient uptake ability of plants, a field experiment was carried out to study the effects of soil temperature and different fertilizer treatments on physico-chemical properties and urease activities in the soil as well as cucumber growth. Two levels of soil temperature (no heating as control (10±2)℃ and heating at (20±2)℃) and three levels of fertilizer treatments (no manure + urea (CK), chicken manure + urea (CMC), swine manure + urea (SMC)) were designed in the experiment. The results showed that applying chicken and swine manure could resist low soil temperature negative effect on cucumber growth and ensure the normal blossom and fruiting, and soil heating enhanced this promoted action. Compared with CK, heating soil improved cucumber yield by 44.33% in chicken manure and 31.08% in swine manure. In addition, heating simultaneously improved fruit soluble protein and pericarp chlorophyll contents, and also decreased nitrate accumulation in fruits. Elevating soil temperature increased cucumber root dry quality, root surface area, root length and root tip numbers. It indicated higher intercepted areas could make the plant absorbing more nutrients. Root at low soil temperatures showed adaptability action to enhance root average diameters and roots thickness. Furthermore, elevating soil temperature improved soil urease activities and facilitated available nutrients transformation. So, in winter out of season cultivation, application of manure and elevating soil temperature could ensure cucumber efficient production and increased fertilizer utilization efficiency.
