Effects of Compound Bio-organic Fertilizer on Flue-cured Tobacco Photosynthetic Physiological Characters & Soil Microbes
摘要
Abstract
In order to explore the effects of compound bio-organic fertilizer mixed with Bacillus subtillis and EM bacteria upon flue-cured tobacco photosynthetic physiological characters & soil microbes,this paper analyzed growth and development,photosynthetic physiological characteristics,economic characters index,chemical compound usable index (CCUI),and soil microbes of flue-cured tobacco 7 d after topping,through comparing the different combined application of this compound bio-organic fertilizer with single chemical fertilizer.The results indicated that the net photosynthetic rate,high-class tobacco rate,average price,yield and value of yield of the compound bio-organic and tobacco economic character index (ECI) were increased by 15.0％ ～ 18.1％,6.84％ ～ 9.50％,2.86％ ～ 3.70％,9.91％～11.90％ and 13.0％～ 16.0％,respectively,compared with the single chemical fertilizer treatment.The usable index (CCUI) of B2F & C3F were increased by 5.78％～ 6.06％ and 3.54％～ 5.28％,respectively,compared with the single chemical fertilizer treatment.And the total amount of 3 microbes,soil-bacteria,fungus and actinomycetes was significantly higher than that by the single chemical fertilizer treatment.This study revealed effect of bio-organic fertilizer application on soil of southern China tobacco/rice rotation regions,where soil fertility was decreased,damages by soil-born diseases became serious,and tobacco yield and quality were all deteriorated owing to the long-term chemical fertilizer application.This paper provided new technical measures for improving soil,where flue-cured tobacco was planted.关键词
