【摘要】 为了探索生物钾肥用于烤烟对改善烤烟钾素营养的作用及效果 ,1995～ 1998年在烤烟上进行了生物钾与 K2 O配合的研究。结果表明 :生物钾可以促进烤烟生长发育 ,增强抗病力 ,提高产量和质量 ,平均提高单产 5 .3% ,增加产值 72 .3元 / 6 6 7m2 ,且技术操作简单 ,成本低 ,可以作为烤烟生产的一项技术普及推广更多还原

【Abstract】 Biotic potassium and K 2O were mixedly applied in tobacco field to investigate effects of improving K nutrition of tobacco in 1995～1998. The results showed that biotic potassium could promote plant growth, enhance disease resistance power, increase its yield and quality, and raise product value of 72.3 yuan/667m 2. The technique could be widely popularized in tobacco production because of easy operation and lower cost.更多还原
