Effects of Herbicides on Greenhouse Gases Emission from Vegetable Plantation Soil
摘要
Abstract
To assess the effects of herbicides on greenhouse gases emission from vegetable plantation soil, an incubation experiment was conducted under laboratory condition with 4 treatments including control, urea, urea+glyphosate and urea+butachlor, and 200 mgN·kg-1 dry soil and 10 mg active ingredient·kg-1 dry soil were applied in urea and herbicides treatments respectively. The experimental results showed that nitrogen fertilizer greatly increased greenhouse gases N2O、CO2 and CH4 emission from the soil, but glyphosate reduced N2O and CO2 emission by 48.4% and 20.2% contrast to urea treatment respectively; butachlor reduced N2O emission 23.2%, not significantly reduced CO2 emission; however, glyphosate and butachlor had no effect on CH4 emission. These indicated the effective influences and the differences of different herbicides on greenhouse gases emission. Therefore, effects of herbicides on greenhouse gases emission should be taken into account in estimation of total greenhouse gases emission amount from agricultural soils in the future.关键词
