Abstract: 【Objective】To study the effects in the precision rice hill-drop drilled field on methane emission.【Method】 Seven treatments were designed, including three precision rice hill-drop drilling types: the first precision rice hill-drop drilling with deep fertilization(30 cm), the second with the alternate line(35 cm＋15 cm) and the third with fixed line(25 cm),using mechanical transplanting, manual seedling broadcasting and manual transplanting as the control groups. Methane samples emitted from paddy field in 2010 and 2011 were collected using a closed-chamber technique. 【Result and conclusion】 The results showed that CH₄ flux was reduced significantly in paddy fields treated by the precision rice hill-drop drilling compared with the non-precision rice field control within three weeks on the rice early tillering stage (reduced by 54.55%, P=0.011). Their flux order of CH₄ emission were as follows, the first precision rice hill-drop drilling with deep fertilization type［(1.48±0.44) mg·m^-2·h^-1］< the second with the alternate line［(1.65±0.30） mg·m^-2·h^-1］< the third with fixed line［(2.57±0.56） mg·m^-2·h^-1］< manual seedling broadcasting［(2.89±0.61） mg·m^-2·h^-1］< mechanical transplanting［(3.77±0.64） mg·m^-2·h^-1］< manual transplanting［(4.76±0.90） mg·m^-2·h^-1］< manual broadcasting［(5.33±0.84) mg·m^-2·h^-1 ］.The present study results showed that the precision rice hill-drop drilling technology can reduce the emission of CH₄ in the pre-tillering paddy field effectively.
