文章摘要：為了明確生物鉀肥對烤煙生長的影響，在云南石林縣對烤煙進行了施用常規(guī)肥料（CK）與生物鉀肥的比較試驗，研究了生物鉀肥對烤煙大田生育期、農(nóng)藝性狀、發(fā)病率、經(jīng)濟性狀等的影響。結(jié)果表明：增施生物鉀肥使烤煙還苗期縮短3d，整個大田生育期提前5d；增施生物鉀肥烤煙的主根長為101cm，極顯著高于CK（89cm）；在團棵期，增施生物鉀肥的烤煙株高為31．5cm，顯著高于CK（29．1cm），在旺長期和封頂后，增施生物鉀肥烤煙的農(nóng)藝性狀與CK差異均不顯著；煙株發(fā)病率和病情指數(shù)，總體上表現(xiàn)為施用生物鉀肥處理較CK低；增施生物鉀肥的烤煙產(chǎn)量、產(chǎn)值和上中等煙比例分別為2565k／h群、52656．0元／hm2、87％，均極顯著高于CK（分別為2475kg／hm2、48892．5元／hm2、78％）�？梢�，增施生物鉀肥有利于促進煙株的生長發(fā)育、減輕病害、提高烤煙的經(jīng)濟性狀。

Abstr：In order to study the effects of biotic potassium on the growth of flue-cured tobacco,the comparative tests were conducted between conventional fertilizer and biotic potassium in Shilin country. The effects of biotic potassium on growth period, agronomic characters, disease incidence and economic characters of the flue-cured tobacco Were studied. The results showed that the see- ding stage was shortened by three days through applying biotic potassium, and the entire field growth period was advanced by five days. The length of taproots by applying biotic potassium was 101 cm and significantly higher than that of the control group （89 cm）. In the rosette stage, the height of plant was 31.5 cm and significantly higher than that in the control group （29. 1 cm）. In the vigorous and capping period, the differences of the agronomic characters were not significant. The disease incidence and disease index of flue-cured tobacco by applying biotic potassium were less than the control group. Moreover,the yield,output value and the upper tobacco ratio after applying biotic potassium were 2 565 kg/ha, 52 656.0 yuan/ha and 87%, respectively, significantly higher than those in the control （2 475 kg/ha,48 892.5 yuan/ha and 780/60 ,respectively）.
