将玉米秸秆在300℃和500℃下裂解制备生物质炭,再按照一定比例(0%,5%,10%,15%)与 NPK化肥混合制成颗粒状生物质炭复混肥料,通过盆栽试验,比较不同生物质炭复混肥对玉米和大豆生长的影响。结果表明,土壤碱解氮和有效磷,种植玉米的土壤比种植大豆的土壤平均分别高21%和25%；与施用常规复混肥相比,施用生物质炭复混肥时,玉米干物质质量增加了6%~58%,平均增加了35%。总体来看,不同处理间土壤性质和作物生物量均没有显著性差异。这一方面说明,肥料效果受肥料本身性质、施肥量、作物等多种因素的影响,另一方面可能与实际输入土壤生物质炭量比较少有关。长期施用生物质炭复混肥料能否对土壤性质及作物生长产生显著的影响还有待进一步研究。

In this study, maize straw was pyrolized at 300℃ and 500℃ . The collected biochar was thoroughly mixed with NPK fertilizer at a series rates of 0% , 5% , 10% , 15% (W/ W), and then made into granular fertilizer. Two pot experiments were established in order to investigate the impacts of these different biochar complex fertilizers on maize and soybean. The re-sults showed that the alkaline-released N and available P content in the soil grown with maize were 21% and 25% higher re-spectively than that grown with soybean. The dry matter of maize grown in the biochar-containing fertilizer was 6% ~ 58% , 35% on average, higher than that in chemical fertilizer. However, in general, there was no significant difference in soil prop-erties and crop dry matter whether, biochar-containing fertilizer or conventional chemical fertilizer was used. It showed that the effect of fertilizer depends on many factors, such as fertilizer property, dose, soil, and crop and even climatic conditions. The small quantity of biochar input into the soil through fertilizer addition may not result in a significant change of soil and plant. Whether long-term application of biochar-containing fertilizer may produce a significant effect on soil properties and crop growth still need further research.
