Effects of Bio-organic Fertilizer and Soil Conditioner on the Growth,Yield and Quality of Flue-cured Tobacco
In order to prevent tobacco bacterial wilt and improve tobacco quality,a field experiment was conducted to study the application effects of soil conditioner (T2 ),bio-organic fertilizer(T3),and mixture of soil conditioner and bio-organic fertilizer(T4)on disease occurrence and tobacco quality.The results showed that,comparing with local conventional fertilization(CK, T1),the output value of T2,T3 and T4 increased by 9.1%,8.9%,7.6%,respectively,and the high grade tobacco increased by 2.6%,3.4% and 3.6%,respectively.The bacterial wilt and mosaic disease indexes of T3 decreased by 22.8% and 56.9%,and those of T4 decreased by 26.3% and 35.0%,respectively.Therefore,application of soil conditioners and bio-organic fertilizer to adjust the soil pH and improve the soil microbial activity could promote the growth and development of tobacco plant.As a result,it would improve the tobacco plant disease resistance,yield and quality of flue-cured tobacco.
