中文摘要：

选取9个生物炭施加比例进行盆栽试验,测定生物炭的施加对吉林西部地区沙化土壤理化性质及绿豆幼苗生长的影响。结果表明,随着生物炭施加比例的增加,土壤的电导率、pH显著升高,土壤吸湿水含量、土壤有机质以及氮磷钾等营养元素含量均有所增加。生物炭的施加对绿豆种子出苗的影响不显著,一定量的生物炭对绿豆幼苗的生长有促进作用,但是生物炭施加比例过高会对绿豆幼苗的生长产生抑制作用。

英文摘要：

Nine different biochar proportions were chosen for pot experiments, to determine the effect of biochar on the physical-chemical properties of sandy soil and mungbean seedling growth in western Jilin province. Results showed that with increase of biochar applied proportion, the soil electrical conductivity and pH were significantly increased, the soil hygroscopic moisture content, soil organic matter and NPK nutrients content increased accordingly. The effect of biochar application on the germination of mung bean seeds was insignificant. The growth of mung bean seedlings was stimulated by a certain amount of biochar, but inhibited in the excessively high biochar proportion.
