摘　　要：采用腐植酸、草本生物炭(秸秆炭)、膨润土、明矾、脱磷石膏5种调理剂及配合施用共设10个处理对高磷土壤磷素转化与吸收的影响进行研究。结果表明,施加调理剂可以有效提高玉米的株高、茎粗与叶绿素含量。在施加调理剂的各处理中,单施明矾和生物炭+膨润土+明矾配合施用处理可以有效增加玉米的生物量,提高玉米的吸磷量。单施膨润土和明矾的处理则可以促进土壤中有机磷的矿化,而单施脱磷石膏以及腐植酸+膨润土+生物炭+明矾+脱磷石膏配合施用趋于土壤钝化,减少磷的移动性,降低环境风险。The effects of a total of ten treatments by the humic acid, herbal biochar（straw charcoal）,bentonite,alum,dephosphorylation gypsum five conditioners and ratio on the conversion and absorption of phosphorus in high-phosphorus soil were studied. The results showed that applying conditioners could effectively increase plant height,stem diameter and chlorophyll content of maize. In each treatment to apply conditioner,the single application of alum and co-application treatment of biochar＋bentonite＋alum could effectively increase the biomass of corn and improve the amount of P uptake of corn. The single application of bentonite and alum could promote the mineralization of organic phosphorus in the soil. Single application of dephosphorization gypsum and humic acid＋bentonite＋biochar＋alum＋dephosphorization gypsum with the application tends to passivation of the soil to reduce the mobility of phosphorus and reduce environmental risks.
