微生物菌剂对许昌烟区烤烟黑胫病防治和烟叶品质的影响

Effects of Microbial Agents on Control of Black Shank and Quality of Tobacco Leaves in Flue-cured Tobacco in Xuchang Area

为探索微生物菌剂在防治许昌烟区黑胫病方面的作用及其对烟叶品质的影响,通过田间试验对施用不同微生物菌剂烤烟的生长发育、病发情况以及品质进行比较。结果表明,微生物菌剂对预防黑胫病效果明显,且能促进烟株生长发育和提高烟叶的化学品质和香气质量,其中以三炬微生物菌剂750kg/hm^2与三炬灌金液7500mL/hm^2搭配施用效果最好。

In order to explore the role of microbial agents in controlling black stem and tobacco quality in Xuchang,the effects of different microbial agents on the growth,disease and quality of flue-cured tobacco were compared.The results showed that microbial agents had obvious effects on preventing black stem,promoting the growth of tobacco,and improving the quality of flue-cured tobacco.As a result,the effect was best if Sanju microbial agent 750 kg/hm^2 was used accommpanying with Sanju Guanjiingye 7 500 mL/hm^2.
