The experiment was conducted under different fertilizer levels to explore the combined effects from allelopathy and the reduced use of fertilizers, with Allelopathy rice 3, Hualiangyou 3, Huazhenyou 3, Nongzhenyou 3 and Hangmeixiangzhan as materials. The results showed that a moderate amount of reducing fertilizer could increase yield and improve quality of rice, the four rice materials with allelopathy characteristics could cause the inhibition of paddy weeds number and biomass, the suppression effect was increasing with the decreased of fertilizer, the Allelopathy rice 3 and Hualiangyou 3 with fertilizer decrease 20% compared with conventional fertilization use could obviously reduce gramineae and broad-leaved weeds, and keep yield and improve quality, the same as Huazhenyou 3 and Nongzhenyou 3 with fertilizer decrease 30%.
Key words: reducing fertilization; allelopathic rice; inhibiting effect; weeds
