中文摘要	球囊霉素相关土壤蛋白(GRSP)和酶活性对调节土壤中生物化学转换以及保持土壤碳、氮、磷循环起到重要作用,为向土壤养分状况改善及农田可持续利用提供理论依据,选择河西走廊地区沙壤土,研究氮磷钾配施(OF)、单施有机肥(CF)以及氮磷钾与有机肥配施(CF-OF)3种基肥处理对蜡熟期玉米根际、非根际易提取球囊霉素土壤蛋白(e-GRSP)、总球囊霉素土壤蛋白(t-GRSP)、碱性磷酸酶活性(ALP)、芳香氨基酶活性(ARY)、脲酶活性(URE)、过氧化氢酶活性(CAT)和beta-氨基葡萄糖苷酶活性(NAG)的影响,以不施基肥(CK)为对照. 结果显示,施用有机肥显著增加了玉米根际、非根际土壤e-GRSP含量,提高了根际、非根际土壤ALP、ARY、URE、NAG,而且根际、非根际以及土层之间差异极显著(P < 0.01),但施肥处理对CAT和t-GRSP影响不明显;相关性分析显示e-GRSP、 t-GRSP、土壤酶活性与碱解氮、有机质、全氮之间呈显著或极显著正相关;逐步回归分析表明e-GRSP、t-GRSP与ALP之间呈极显著的线性关系(P < 0.001). 本研究表明在干旱半干旱区沙壤土中基施有机肥能改善与土壤碳、氮、磷循环密切相关的土壤酶活性,提高GRSP含量,从而提高土壤肥力.
英文摘要	Glomalin-related soil protein (GRSP) and soil enzyme activity play very important roles in the regulation of biochemical conversion and maintaining soil C, N, and P cycles. In addition, they provide a theoretical basis for the improvement of soil nutrient status and the sustainable utilization of farmland. Sandy loam of the Hexi Corridor was chosen as research material, and three different base fertilizer treatments were applied to maize, including chemical fertilizer(OF), organic fertilizer (CF), chemical fertilizer + organic fertilizer combined application (OF-CF), and no fertilizer as contrast (CK). The influence on easily extractable glomalin-related soil protein (e-GRSP), total glomalin-related soil protein(t-GRSP), activity of alkaline phosphatase (ALP), aromatic aminase (ARY), urease (URE), catalase (CAT), and N-acetyl-beta- glucosaminidase (NAG) from the rhizosphere and non-rhizosphere were determined. The use of organic fertilizer significantly increased the e-GRSP content, and soil activity of ALP, ARY, URE, and NAG in the rhizosphere and non-rhizosphere. There were significant differences between the rhizosphere, non-rhizosphere, and soil layers (P < 0.01). However, the effect of base fertilizer treatments on CAT and t-GRSP was not obvious; correlation analysis between e-GRSP, t-GRSP, soil enzyme activity, and available nitrogen, organic carbon, and total nitrogen revealed the existence of significant or extremely significant positive relationships. Stepwise regression analysis showed that e-GRSP and t-GRSP had a significant linear relationship with ALP (P < 0.001). Organic fertilizer helps to promote the overall ascension of maize rhizosphere soil quality, GRSP content, and enzyme activity of soil, which improves the contribution of C, N, and P recycling of sandy loam in arid and semi-arid regions.
