Abstract: Biochar fertilizer is a stable carbon-rich solid product formed by thermal cracking of biomass under anoxic conditions.To explore the application of biomass charcoal fertilizer in agriculture,the 10 Maize breeds (Huake 425,Dedan 1001,Xianyu 335,Dafeng 30,Zhongkeyu 505,Bixiang 809,Heyu 185,Hudan 9,Xianyu 696 and Jinzhengtai 622) and the 5 rice breeds (Longyang 16,Xinhu 122,Daohuaxiang 2,Rice 209 and Qing 20-4) were evaluated for the effect of biochar fertilizer through field experiments.The results showed that the yield of 8 maize breeds was increased significantly by 10.02%-24.32% after the application of biochar fertilizer,including Huake 425,Dedan 1001,Xianyu 335,Dafeng30,Zhongkeyu 505,Bixiang 809,Heyu 185 and Hudan 9.Among the 5 rice breeds,only the production of Longyang 16 and Xinhu 122 were improved significantly,by 13.00% and 11.54%,respectively,and only 1 000-grain weight of Xinhu 122 was increased significantly.These results indicated that the effect of biochar fertilizer was different among the breeds of crops.
