摘要
本文总结了七年来生物钾肥（硅酸盐菌剂）在七个烟草生产省份中试验、示范、推广的结果，证明施用这种生物肥料不但可以改善烟叶品质、提高烟叶产量、改良烟田土壤、减少化学钾肥施用量、减少烟叶病害，而且施用方法简便又不破坏生态环境。推广这项技术可带来可观的经济效益和生态效益。
A series of experiments were carried out at seven provinces in China for seven years to test the.effect of silicate bacterial fertilizer on tobacco (raising the Per unit yield,improving the quality. improving the tobacco soil,decreasing in number of chemical fertilizer,alleviating tobacco diseases).The results were summed up in this paper.
