Abstract: Charcoal based fertilizer was the long- term fertilizer mixing the biochar and conventional fertilizers, which had the characters of high efficiency, no pollution, improving soil physical and chemical properties, and reducing the use of chemical fertilizers and pesticides. To select the suitable charcoal base fertilizer with better sustained release effect for maize production, the effects of four charcoal base fertilizers mixing carbon powder and nitrogen nutrient with different proportion on the yield of maize ‘Huayu8’ were studied with the same fertilizer rate compared with conventional fertilizer. The results indicated that, the experimental treatment of adding self-made carbon based SRFS and rice hull char respectively could improve the agronomic traits of maize effectively, increasing plant height, stem diameter and root number. The yield of maize of adding self-made carbon based SRFS was 7.64% higher than OF and had significant difference between them. Compared to OF, C-SRF2, C-SRF3, C-SRF4 did not make the corn yield increase apparently.
