广州地区用蘑菇底肥控制稻田甲烷排放

Control CH_4 Emission from Paddy Fields by Using Mushroom Fertilizer in Guangzhou Region

采用华南地区常用施肥方式,即有机肥加化肥,在广州地区设计2种施肥方式:①猪粪加化肥,②蘑菇肥加化肥,在肥效和灌溉条件基本相同情况下,监测晚稻田甲烷排放通量。实验证明,在产量基本相同下,广州地区晚稻施用蘑菇底肥比猪粪底肥可大大地降低甲烷的排放。

Organic fertilizer (base fertilizer) plus chemical fertilizer is widely used in South China. Two fertilizer ways were design in Guangzhou Region, which were pig-dung plus chemical fertilizer and mushroom fertilizer plus chemical fertilizer. On the same fertilizing effects and irrigation condition, the CH_4 emission flux from paddy fieldswas monitored. The experiments show that, on the same rice production condition, CH_4 Emission could be reduced by using mushroom base fertilizer instead of pig-dung base fertilizer in paddy fields in Guangzhou Region.
