摘要
对当前传统水稻栽培技术对稻田甲烷气体排放以及化肥、农药施用后造成环境污染的现状进行了分析。采用膜下滴灌水稻栽培技术能够有效降低甲烷气体排放,减少施用化肥、农药对环境的污染;同时,膜下滴灌水稻比传统水稻在节水、增产方面有明显优势。
The status of environmental pollution induced by methane emission, fertilizer and pesticide in traditional rice cultivation techniques was analyzed. Rice cultivated by drip irrigation under mulch film could significantly decrease the e- mission of methane and reduce the pollution by fertilizer and pesticide. At the same time, compared to traditional rice, rice with drip irrigation under mulch film had clear advantages on yield - increasing and water - saving.
