针对山地烟区连作问题持续存在的现状,对典型烟区和烟农进行了广泛深入调查分析,围绕连作条件下土壤酸碱度调控,团粒结构改善,有益微生物群落恢复等方面开展了大量研究工作,形成了冬耕冻土、绿肥还田、施用有机肥、硝酸钾部分替代硫酸钾、施用陪嫁土和生石灰等土壤保育与修复的相关技术措施.通过大面积推广与应用,取得了良好成效,可为开展土壤生态保护工作提供有益参考.%According to the current situation of continuous cropping problem in mountainous regions which will remain for a certain period, an in-depth investigation on typical areas and farmers was executed by Enshi tobacco company of Hubei Province. A lot of related research (i.e.: soil pH of regulation, crumb structure improvement, beneficial microbial community restoration) were carried out, and a number of ecological protection and remediation technologies (i.e..: ploughing, green manure technology, organic manure fertilization, potassium nitrate, nutrition soil and lime application) were developed. The integration of the technologies was successfully applied to the recovery and development of Enshi tobacco producing regions, which can provide useful reference for other tobacco growing regions and other agricultural systems.
