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
