摘要
[目的]防治豫东地区烟草虫害。[方法]设综合防治区、常规防治区和空白对照区,研究豫东地区烟区烟青虫、烟蚜、地老虎的发生规律及综合防治技术。[结果]豫东地区烟青虫、地老虎的防治适期分别为5月24～28日、4月25日～5月2日。田间蚜量消长为双峰型,与环境因子关系极为密切。麦套烟与烟草纯作相比烟蚜减少40%～80%。综合防治区上等烟比例是常规防治区的2倍,比常规防治区增产319.5～583.5 kg/hm^2。[结论]以农业生态防治为基础,以烟草健株栽培为重点,必要时结合化学防治,确保烟草丰产质优。
[Objective] The aim of the study was to control the insect pests of tobacco in eastern Henan so as to increase the economic benefit.[Method] The integrated and conventional control areas and blank contrast area were set up to study the change law and integrated control technology of Heliothis assulta,Myzus persicae and Agrotis ypsilon in tobacco planting areas of eastern Henan.[Result] The suitable periods for controlling H.assulta and A.ypsilon in eastern Henan were May 24th～28th and Apr.25th～May 2nd.The population dynamics of M.persicae in the field was double-peak type and had very close relationship with environmental factors.Compared with singly planting tobacco,the M.persicae reduced 40%～80% on the tobacco intercropped with wheat.The proportion of super tobacco in integrated control area was 2 times of that in conventional control area and its yield increased 319.5～583.5 kg/hm2 in comparison with conventional control area.[Conclusion] With agro-ecological control as base,cultivation of healthy to bacco plant as emphasis,combining with chemical control when it was necessary,the high yield and good quality of tobacco could be ensured.
