中文摘要	研究干旱区绿洲农田不同种植模式和秸秆管理下土壤有机碳及其酶活性的变化,揭示农业管理措施对土壤质量的影响,以期为干旱区农业资源高效利用及可持续发展提供理论依据.在作物种植规划区,选择新疆主要农作物棉花、小麦、玉米,设计长期连作及轮作试验.结果表明:轮作处理土壤有机碳(SOC)、微生物生物量碳、易氧化有机碳、水溶性有机碳、热水溶性有机碳含量较连作处理分别提高了3.6%~9.9%、41.8%~98.9%、3.3%~17.0%、11.1%~32.4%、4.6%~27.5%;秸秆还田处理较秸秆不还田处理分别提高了12%~35.9%、22.4%~49.7%、30.7%~51.0%、10.6%~31.9%、41.0%~96.4%.轮作处理土壤过氧化氢酶、脱氢酶、beta-葡萄糖核苷酶、蔗糖酶、纤维素酶活性较连作处理分别提高了6.4%~10.9%、6.6%~18.8%、5.9%~15.3%、10.0%~27.4%,28.1%~37.5%;秸秆还田处理较-秸秆不还田处理分别提高了31.4%~47.5%、19.9%~46.6%、13.8%~20.7%、19.8%~55.6%、54.1%~70.9%.相关性分析表明,SOC及其活性组分与土壤酶活性之间有极显著的正相关关系,利用土壤活性有机碳组分和酶活性变化可有效表征农田SOC和土壤质量变化.通过因子分析综合评价得知,在干旱区农业生产中,短期连作棉花兼实施秸秆还田可提高SOC及其活性组分含量和酶活性,合理轮作可有效缓解连作障碍,使土壤质量得到进一步改善,有利于农田土壤的可持续利用.
英文摘要	To reveal the regulatory mechanism of agricultural management practices on soil quality, an experiment was carried out to study the different cropping system and straw management on soil organic carbon and fractions and soil enzyme activity in farmland of arid oasis region,which would provide a scientific basic for enhancing agricultural resources utilization and sustainable development. In crop planting planning area, we took the mainly crop (cotton, wheat, maize) as research objects and designed long-term continues cropping and crop rotation experiments. The results showed that the soil organic carbon ( SOC ),soil microbial biomass C,labile C,water-soluble organic C,and hot-water-soluble organic C content were increased by 3.6% - 9.9%, 41.8% -98.9%, 3.3%-17.0%, 11.1% 32.4%,4.6%-27.5% by crop rotation compared to continues cropping, and 12%-35.9%, 22.4%-49.7%, 30.7%-51.0%, 10.6%-31.9%, 41.0%-96.4% by straw incorporated compared to straw removed, respectively. The soil catalase, dehydrogenase, beta-glucosidase,invertase glucose, cellulase glucose activity were increased by 6.4%-10.9%, 6.6%-18.8%, 5.9%-15.3%, 10.0%-27.4%,28.1%-37.5% by crop rotation compared to continues cropping, and 31.4%-47.5%, 19.9%-46.6%, 13.8%-20.7%, 19.8%-55.6%, 54.1%-70.9% by straw incorporated compared to straw removed, respectively. There were significant positive linear correlations among SOC,labile SOC fractions and soil enzyme. Therefore, we concluded that labile SOC fractions and soil enzyme were effective index for evaluating the change of SOC and soil quality. Based on factor analysis, in arid region, developing agricultural production using cropland management measures, such as straw-incorporated and combined short-term continues cotton and crop rotation,could enhance SOC and labile SOC fractions contents and soil enzyme activity,which could improve soil quality and be conducive to agricultural sustainable development.
