| 摘要: |
| 为探索生物炭对玉米生长和产量的影响，开展了不同生物炭施用量对玉米生长和增产效果的研究。结果表明：施用生物炭对玉米的性状基本无影响，对玉米产量影响极显著，施用生物炭 4 500~5 250 kg/hm 2 能够使玉米增产 10%、15%。 |

| Abstract: |
| In order to explore the effect of biochar on growth and yield of maize，the effects of different biochar application rates on the growth and yield-increasing of maize were studied. The results showed biochar application had no effect on maize traits，but significantly affected the yield of maize.The maize yield increased by 10%-15%，when applying biochar 4 500-5 250 kg/hm 2 . |
| Key words: maize biochar application rate yield trait |
