摘要: 為初步了解菜籽餅?zāi)軌蛱岣呖緹熎焚|(zhì)的效用機(jī)理,，通過田間試驗(yàn)，研究了不同施肥尤其是菜籽餅對烤煙根際微生物的影響,。結(jié)果表明,，施用菜籽餅對烤煙根際微生物促進(jìn)最顯著；但煙葉成熟期,，較高的氨化及硝化細(xì)菌數(shù)量不利煙葉的成熟落黃,。因此，在烤煙生產(chǎn)實(shí)踐中,，適時(shí)適量施用餅肥十分重要,。Abstract: In order to understand the mechanism why rapeseed cake application could improve the quality of flue-cured tobacco, a field experiment was conducted to investigate the effect of different fertilization, especially rapeseed cake on the microorganism in rhizosphere soil of flue-cured tobacco. The results showed that fertilization with rapeseed cake increased most significantly the amounts of microbes. However, too many ammonifying and nitrifying bacteria could impede the yellowing and maturity of tobacco leaves during maturity stage. It is important to apply cake fertilizer at proper time and in suitable rate to tobacco .
