本文调查了稻草还田对烟草主要病虫害—烟草普通花叶病、青枯病、黑胫病、根黑腐病、赤星病、烟蚜、小地老虎、野蛞蝓及斜纹夜蛾发生的影响。结果表明 ,经过稻草还田的烟田主要病虫害的发生程度明显轻于常规的田块 ,说明稻草还田能明显减轻烟草主要病虫害的发生。
The present paper deals with influence on mulch farming to the main pests and diseases, tobacco mosaic virus (TMV), tobacco granuville wilt [Pseudomonas solanacearum E.F. Smith], tobacco black shank [Thielaviopsis basicola (Berk. et Br.)
