枯草芽孢杆菌有机肥对土壤条件及烤烟产质量的影响

为探明枯草芽孢杆菌有机肥在烤烟生产上的应用效果,通过小区试验,研究了不同施肥方法对植烟土壤养分、微生物种群数量和烟叶产质量的影响。结果表明,在云南曲靖宣威地区配施枯草芽孢杆菌有机肥,与常规施肥方法相比,植烟土壤有机质、速效磷、速效钾和全钾含量分别提高8.38%、12.59%、5.51%和10.59%,使土壤细菌、放线菌数量分别增加177.66%和118.18%,真菌数量降低121.43%;上等烟比例提高1.82%,均价提高2.51%,有利于提高下部、上部初烤烟叶钾离子含量和内在化学成分的协调性,并改善抽吸品质。

Effects of Bacillus subtilis Organic Fertilizer on Soil Conditions,Yield and Quality of Flue-cured Tobacco

In order to investigate the application effects ofbacillus subtilis organic fertilizer (BOF) on flue-cured tobacco production, a field experiment was carried out to study the influences between different application methods on soil fertility, microorganism quantity, yield and quality of flue-cured tobacco in Xuanwei City, Yunnan Province. The results indicated that the contents of organic material, available P and K, total K in soil of combined application with BOF increased by 8.38%,12.59%,5.51% and 10.59% compared with conventional fertilization, respectively, the quantity of actinomycetes and bacteria increased by 177.66%,118.18%, furthermore, there is a drop of 121.43% on fungi. The ratio of high grade leaves and the average price of tobacco leaves increased by 1.82% and 2.51%.In addition, it was helpful to increase the potassium content, coordination of chemical composition and smoking quality of lower and upper flue-cured tobacco leaves.
