摘要: Accumulation of nitrate in soil increases the risk leaching and hence ground water pollution. The impact maize intercropping with ryegrass alfalfa on environment farming systems has been little studied China. Using life cycle assessment (LCA) method, we analyzed effects different cropping (sole (CK), + (CRT), (CAT)) environment. comprehensive index environmental impacts varied order, sole maiz>maize ryegrass>maize alfalfa, corresponding values 0.1421, 0.1353 0.1299, respectively. results showed that could reduce adverse overapplication nitrogen fertilizer study further demonstrated LCA method may be a convenient effective approach for analyzing management agricultural fields.
