摘　　要：生物炭和玉米秸秆具有改良土壤质量、促进作物生长的作用,其改良效果因物种不同而存在差异,探究不同作物生长性状和养分吸收效率对生物炭和玉米秸秆的响应差异对农业生产具有实践意义。以大白菜、冰草、石竹和紫花苜蓿4种不同科属的作物为材料,采用盆栽试验,分别设置不添加物料、添加生物炭、添加玉米秸秆、生物炭与玉米秸秆配施处理,分析不同处理下土壤养分变化、作物生长和养分吸收的变化规律。结果表明,生物炭、玉米秸秆以及二者配施影响了土壤养分(全氮、有效磷、速效钾和有机碳)含量,变化幅度分别在-28.78%~40.41%、-17.85%~53.20%、-3.45%~62.51%。生物炭与玉米秸秆配施影响了4种作物的生长,其中,地上部干重增加23.74%~80.89%。生物炭、玉米秸秆以及二者配施使根长分别增加22.51%~77.91%、25.86%~80.45%和45.93%~149.24%,养分吸收效率分别提高3.40%~143.73%、1.07%~188.80%和9.82%~290.32%。施用生物炭和玉米秸秆对4种作物的生长均有明显的改善,生物炭和玉米秸秆增加了土壤养分,促进了作物养分吸收,促进了作物地上部和根部的生长。研究结果为生物炭和秸秆的广泛利用和推广提供了理论基础。Biochar and maize straw can improve soil quality and promote crop growth,but their improvement effects may vary in different crop species.It is of practical significance for agricultural production to explore the difference of response of different crop growth traits and nutrient absorption efficiency to biochar and maize straw.A pot experiment was carried out on Chinese cabbage,agrostis,caryophylla and alfalfa with no material added,biochar added,maize straw added,biochar combined with maize straw,respectively,to analyze the changes of soil nutrients,crop growth and nutrient absorption.The results showed that the contents of soil nutrients(total nitrogen,available phosphorus,available potassium and organic carbon)were affected by biochar,corn straw and their combined application in the range of-28.78%~40.41%,-17.85%~53.20%and-3.45%~62.51%,respectively.The combined application of biochar and maize straw significantly affected the growth of 4 crops,and the above-ground dry weight increased by 23.74%~80.89%.The root length increased by 22.51%~77.91%,25.86%~80.45%and 45.93%~149.24%,and the nutrient absorption efficiency increased by 3.40%~143.73%,1.07%~188.80%and 9.82%~290.32%,respectively,under the treatments of biochar,corn straw and their combined application.The application of biochar and maize straw significantly improved the growth of the 4 crops.Biochar and maize straw increased the soil nutrients,promoted the nutrient absorption of crops,and promoted the above-ground and root growth of crops.Above results provided a theoretical basis for the extensive utilization and popularization of biochar and straw.
