通过分析、总结长期试验的研究进展,研究长期试验的特点、意义和研究内容,综述了长期试验对土壤理化性质、土壤微生物量的影响,有助于该学科研究的纵深发展与广泛利用.目前,长期试验通常采取2种方法,分别是“长期”和“定位”,其具有时间的长期性和气候的重复性等特点,能够克服各种生态因素差异对试验带来的影响和制约;其与土壤理化性状和微生物特性等关系密切,对研究农业生产有着重要的科学价值,为不同措施对土壤性质的影响提供研究场所.

Through analyzing and summarizing the progress of long‐tem experiment ,studying the characteris‐tics ,meaning and contents of long‐term experiment ,the effects of long‐term experiment on soil physical and chemical property and soil microbial biomass ,long‐term experiment progresses at home and abroad were ana‐lyzed and summarized .At present ,long‐term experiment ,which chooses methods of ‘long‐term’ and ‘located’ , has the characteristics of long time and repeatability of climate ,could overcome influence and restraint of exper‐iment from different ecological factors ;Long‐term experiment has close relationship with soil physical and chemical property and soil microbial biomass ,which would be important for modern agriculture ,provide field for studying the effect of different measures on soil properties .
