不同抑芽剂对烤烟腋芽生长及烟叶产量、质量和安全性的影响
Effects of Different Germ Inhibitors on Axillary Bud Growth,Yield,Quality and Safety in Tobacco
摘要
Abstract
Field plot trials were conducted in Dali and Shilin from 2021 to 2022 with Yunyan 87 as the test material.The effects of pendimethalin,butralin and flumetralin on axillary buds inhibition of tobacco and yield and quality of tobacco,as well as the residual amount of bud inhibitors in tobacco after roasting were studied.The results showed that the use of germination inhibitors improved axillary bud inhibition in tobacco plants and was optimized at 14 d after application.Meanwhile,the use of germ inhibitors increased the yield of roasted tobacco,the proportion of medium,high quality tobacco,and the value of production.Among them,the highest yield per hectare,value of production per hectare,and proportion of medium to high quality tobacco were obtained with the butralin treatment in Dali in 2021 and in Shilin in 2022,in which yields increased by 22.82% and 58.80%,production value increased by 40.76% and 78.87% respectively.For the Dali experimental station in 2022,the best treatment was 50% butralin + 50% flumetralin,in which tobacco production and output increased by 8.59% and 20.39% respectively.Furthermore,under rational application of germicidal agents at recommended dosages,the pesticide residues in the roasted tobacco were lower than the maximum residue limits set by the Cooperation Center for Scientific Research Relative to Tobacco(CORESTA).In conclusion,butralin treatment is a better choice to improve the axillary bud inhibition effect of tobacco plants,enhance the yield and quality of tobacco and increase the economic benefits.关键词
