摘要
对节水灌溉条件下稻田温度、土壤通气性、杂草生长及病虫害、温室气体的排放和矿质营养等生态环境因子的变化及规律进行了归纳总结,分析了节水灌溉条件下稻田温室气体CH4和N2O的排放变化及其综合效应,提出今后应加强节水灌溉条件下稻田杂草及病虫害的防治策略、稻田温室气体排放及水肥耦合效应等稻田生态环境方面的研究.
A discussion was made on the variation regularities of some ecological and environmental factors of paddy field under water-saving irrigation condition, mainly including the temperature of paddy field, ventilation of soil, weed growing and insect pests, emission of greenhouse gases, and balance of mineral nutrition. The gases CH4 and N20 released from paddy field under water-saving irrigation condition and their comprehensive effect were particularly analyzed. It is suggested that the strategies for controlling of weed growing and insect pests, greenhouse gas emission from paddy field, and effect of water-fertilizer coupling under water-saving irrigation condition should be emphasized in further study.
