减农药配施炭-醋材料对烟草生长与病害的影响

Reducing Pesticide with the Mixture of Pyroligneous and Charcoal:Effect on Tobacco Growth and Disease

为减少烟草种植过程中农药的过量施用问题,减轻农药污染,以烟草为试验对象,通过田间小区试验,研究减量农药配合炭-醋材料对烟草的农艺性状、产量、质量、病害和经济效益的影响。研究结果表明,与常规施用农药相比,减量农药配合炭-醋材料能促进烟草旺长期的农艺性状,抑制田间病害的发生,对产量、质量和产值无显著影响。减量农药10%~20%配合炭-醋材料能使烟草正常生长,满足对产量、品质及产值的需求。

The paper aims to reduce the pollution resulted from the overuse of pesticides during the process of tobacco planting. Through a field plot experiment, we studied the influences of reducing pesticide combined with the mixture of pyroligneous and charcoal on tobacco agronomic traits, yield, quality, disease and economic benefits. The results showed that： compared with the conventional use of pesticides, reducing pesticides combined with the mixture of pyroligneous and charcoal could improve agronomic traits of tobacco during vigorous growth period and inhibit the occurrence of diseases without obvious change in yield, quality and output value. Pesticides reduction of 10%-20% combined with proper amount foliage spraying of wood vinegar could assure the normal growth of tobacco and satisfy the demand of yield, quality and economic benefits.
