根际土壤调控对连作烟田青枯病的控制作用
Bacterial wilt control in continuously cropped tobacco field by manipulation of rhizosphere soil
摘要
Abstract
Organic tobacco leaf production is confronted with major issue of accumulation of bacterial wilt in soil continuously cropped with tobacco. Problems such as soil compaction, acidification, unbalanced nutrients also exist, especially in southern tobacco growing areas. In order to improve tobacco growing soil, measures were taken such as socket application with carbonization corn straw, increased application of alkalinity fertilizer, root irrigation with quicklime water and micro-fertilizer tradecorp were applied. Agronomical characters and occurrence of tobacco bacterial wilt were analyzed. Results showed that both root irrigation and micro-fertilizer tradecorp were good to prevent and control tobacco bacterial wilt with control efficacy of 50.52% and 40.47%, respectively. All four measures showed positive effects on tobacco agronomic character, with socket application of alkalinity fertilizer the best and root irrigation with micro-fertilizer tradecorp, root irrigation with quicklime water and socket application with carbonization corn straw also effective.关键词
