Effects of insecticides on greenhouse gas emission in soil
摘要
Abstract
In order to assess the effects of the insecticides imidacloprid and chlorpyrifos on greenhouse gases emission in soil, an incubation experiment was conducted under laboratory condition with 8 treatments control, urea, urea+imidacloprid (5, 10 and 50 mg active ingredient·kg-1 dry soil, respectively) and urea+chlorpyrifos (5, 10 and 50 active ingredient·kg-1 dry soil, respectively), 200 mgN·kg-1 dry soil was applied in each soil sample of urea and pesticides treatments respectively. The results showed that urea ferti-lizer applied greatly increased greenhouse gases N2O and CO2 emission from the soil, but had no significant effects on CH4 emission. The imidacloprid had no effect on soil CO2 and N2O emission under 5 mg·kg-1 treatment,but showed significant negative effect at10 and 50 mg·kg-1, compare with urea treatment it reduced the N2O emission 26.89%and 53.10%respectively (P<0.05), and decreased the CO2 emission 15.14%and 13.79%respectively (p<0.05). The N2O emission under the three concentration levels of chlorpyrifos showed no significant differences compared with the urea treatment, however under 5 and 10 mg·kg-1 dry soil concentration the chlorpyrifos had significant decreased the CO2 emission 19.88% and 19.02% respectively (P<0.05). Both the imidacloprid and chlorpyrifos showed no significant differences compared with urea treatment on CH4 emission under the three concentration levels. The results indicated that insecticides had great influences on greenhouse gases emission but the influences were different with types and concentrations.关键词
