Abstract:In order to determine suitable application amount of biotic-potassium fertilizer in Baise area of Guangxi province,a field experiment was carried out to investigate the effects of biotic-potassium fertilizer application amount on main soil nutrient contents,yield and quality of flue-cured tobacco in Baise area. The results showed that the application of biotic-potassium fertilizer could increase major nutrient content in soil,especially the content of available potassium,organic matter,alkaline hydrolysis nitrogen,enhance the economic benefit significantly. The economic character of the treatment with 45 kg/ha biotic-potassium fertilizer was the best, the yield, production value,average price and ratio of superior leaf of the above treatment increased by 11. 23%,18. 41%,6. 39% and 25. 62% compared with the treatment without biotic-potassium fertilizer( CK) . On the whole,the application of biotic-potassium fertilizer could improve the quality of flue-cured tobacco, maintain better chemical component content and harmony,increase the content of potassium and major aroma components and total aroma components obviously, increase the smoking score,especially the treatment with 45 kg/ha biotic-potassium fertilizer,which was 76. 2. There-fore,the best application amount of biotic-potassium fertilizer was 45 kg/ha in Baise tobacco-growing area.
