Preliminary Study on the Replacement of Part of Chemical Fertilizers with Organic Fertilizer in Anlu City Rice
Abstract：To reduce excessive and unreasonable application of chemical fertilizers and optimize fertilization methods, this study set up five treatments: blank control, conventional fertilization, recommended fertilization, organic fertilizer replacing 15% of chemical nitrogen, and organic fertilizer replacing 30% of chemical nitrogen. The effects of different fertilization methods on soil physical and chemical properties and rice yield were compared. The results showed that there was no significant difference in the impact of organic fertilizer replacing part of chemical fertilizer on soil physical and chemical properties, but it could significantly increase rice yield by improving the effective panicle number and grains per panicle. Among them, the treatment of replacing 15% of chemical nitrogen with organic fertilizer showed the best effect in increasing rice yield, reaching 12,498 kg/hm², with a significant yield increase and an additional economic income of 4,670.98 yuan/hm².
