| 摘 要： | 采用田间盆栽试验,研究了生物炭（biochar）对玉米（Gramineae）苗期生长（60 d）及土壤化学性质的影响。结果表明,在玉米苗期的前33 d,生物炭（48 t.hm-2）对玉米株高的生长有显著抑制作用,但随着玉米的生长发育,生物炭的抑制作用逐渐消失。收获时（播种后60 d）,生物炭对玉米植株干质量,N、P养分的吸收量没有显著影响;生物炭（12、48 t.hm-2）能显著提高土壤全N、有机碳质量分数,但对土壤全P、有效P、pH值没有显著影响。土壤全N、有机碳质量分数与生物炭用量（0、2.4、12、48 t.hm-2）为显著正相关（n=12,p〈0.01）。

| Abstract: | Pot trial was adopted to study the effects of biochar on corn growth（60 d）,nutrient uptake and soil chemical properties in seeding stage.It was shown that biochar（48 t·hm-2） significantly decreased corn height from 13 to 33 days after sowing,but the inhibition effects of biochar gradually disappeared after 39 days.Biochar did not significantly affect the corn dry weight,nitrogen uptake（g·pot-1） and phosphorus uptake（g·pot-1） in seeding stage.Biochar（12,48 t·hm-2） significantly increased soil organic carbon and total nitrogen,but did not significantly affect total phosphorus,available phosphorus and pH.Soil total N,soil organic carbon and biochar amendment rates（0,2.4,12,48 t·hm-2） had significantly positive correlation（n=12,p0.01）. |
