Abstract:

In order to understand the application effect of rice-straw application combined with decomposing agent on tobacco.The pot culture experiment was conducted to analyze the variation of the tobacco's growth,yield,chemical composition and coordination after the rice-straw application combined with chemical fertilizer and decaying agent containing different microbial dominant strains respectively,the research object was to explore the effects of rice-straw application combined with decomposing agent on the tobacco's growth,yield and quality.The results showed that the rice-straw application combined with decaying agent significantly increased the stem circumference,maximum leaf area,biomass,yields and the ratio of medium & superior grade of tobacco.The rice-straw application combined with decaying agent significantly lowered nicotine content of the upper tobacco,and increased its' total sugar content,reducing sugar content and total sugar-nicotine ratio,which resulted in reducing the irritability,bitterness and pungency of the upper tobacco and improving its' smoking quality;meanwhile,the rice-straw application combined with decaying agent significantly raised the content of total nitrogen,total sugar and reducing sugar in central tobacco,but there were no obvious variations for the ratio of total nitrogen to nicotine,reducing sugar total nitrogen and reducing sugar to nicotine,which meant the effect of rice-straw application combined with decaying agent on the central tobacco's chemical coordination was not significant;moreover,the rice-straw application combined with decaying agent increased the content of total sugar and reduced sugar in lower tobacco,and raised its' ratio of reducing sugar to total nitrogen and sugar to nicotine,which was beneficial to increase the aroma of lower tobacco and reduce its' impurity.According to the results of principal component regions between tobacco's agronomic characters and biomass,chemical composition and coordination indexes of different parts of cured tobacco,the rice-straw application combined with the decomposing agent containing dominant microorganism of bacteria+fungi or bacteria+fungi+actinomycetes had no significant difference in promoting tobacco's growth,yield and quality.Therefore,the rice-straw application combined with the decomposing agent containing different types of dominant microorganism could promote tobacco's growth,rationalize the chemical composition of upper and lower tobacco,and be beneficial to improve its sensory quality and increase tobacco's yield and quality.
