摘 要: | 农田长期定位试验是研究农田长期生态过程及其环境效应和调控措施的重要手段。作为2种最普遍和频繁的农业生产活动,施肥和保护性耕作对农田生产力和生态环境过程产生深刻影响。本文通过检索、收集1979-2009年有关我国农田长期施肥和保护性耕作试验的研究论文,提取试验案例中试验站点分布、土壤类型、作物系统、监测区间及建站时间、管理措施、研究内容、试验小区面积及站点管理单位等实验要素及相关信息,并分析其分布特征。在此基础上,探讨我国农业生态系统长期试验存在的问题及今后的发展方向并提出对策。

Abstract: | Long-term field experiment is an important way to study long-term ecological process with its environmental effect and control measure of cropland.Fertilization and cultivation in the agricultural production are the two most common and frequent management practices, which have a profound impact on agricultural productivity and ecological processes.Publications were collected under long-term agro-ecosystem experiments with different fertilizations and conservation tillage treatments which were availabled from the Chinese Journals Database (CNKI) and the Chinese Journals of Science and Technology Database (VIP Info ) during 1979 to 2009. And informations of trial site distribution, soil types, crop systems, monitoring durations and site set-up time,management measures, research content, testing area and oriented units were extracted from the publications above to analyze the long-term experiment status and distribution characteristics,and discuss the existing problems, progresses and proposed countermeasures of long-term agro-ecosystem experiments in mainland China. |
