摘  要：
通过田间小区对比试验,研究生物黑炭作为改良剂与堆肥等其他生物质改良剂相比对新疆低产土壤———灰漠土的改良和玉米增产的效果。结果表明,施入20t·hm-2和40t·hm-2的生物黑炭,能显著提高土壤有机质含量,与基础土壤相比,提高了22.77%和49.80%,明显高于秸秆还田、羊粪和腐植酸有机肥等对土壤有机质的提升效果。施用生物黑炭提高了玉米单穗重、千粒重、产量以及生物量,降低了玉米的根冠比,促进玉米根系生长,而追施氮肥对玉米产量的影响差异不显著。因此,施用生物黑炭能够大幅度提高土壤有机质含量,对灰漠土土壤质量和作物产量以及农艺性状的提高具有重要作用。

摘  要：
Biochar carbonized from straws or other agriculture wastes applied in soil as a important way to decrease greenhouse gas emission and enhance carbon sequestered was frequently studied by lots of scientists recently. So this text to study on the effect of the biochar to modify grey desert soil and the maize yield by comparison with the other biomass amendment through the plot trials. The results showed that:soil organic matter with biochar of 20 t·hm-2 and 40 t·hm-2 applied was increased by 22.77% and 49.80% respectively compared with control plot, and organic matter content in soil of biochar applied was significantly higher than that of farm manure, straw returning, humic acid fertilizer amended. Meanwhile, biochar amended could increase single spike weight, thousand kernel weight, yields and biomass, and decrease maize root-shoot ratio and improve root growth, but no obvious difference with different dosage N fertilzer utilized. So, biochar application could not only improve maize physiological characters and increase yield, but also promote soil organic matter content and decrease content of N fertilizer applied in Xinjiang. Biochar from straw or other agriculture waste carbonized applied in soil would be considered as an effective way to promote soil fertility and productivity.
