摘　　要：利用玉米秸秆为有机物料,以黑穗醋栗(Ribes nigrum L.)品种寒丰为试材,通过秸秆与土按比例混拌回填,秸秆、微生物菌剂和腐熟剂按不同比例混拌回填,不同比例氮肥施入共5个处理,以不施入为对照,测定施入前后土壤理化指标和产量。结果表明,添加玉米秸秆、微生物菌剂和腐熟剂可增加土壤有机质、降低pH,减小土壤容重、增加土壤氮含量;施用氮肥降低土壤有机质和pH,增大土壤容重、增加土壤氮含量;5个处理土壤全磷、缓效钾变化规律不明显,速效磷和速效钾的动态变化都是呈先下降后上升或平缓的趋势;5个处理黑穗醋栗产量均高于对照。Corn straw was used as organic material,and black currant(Ribes nigrum L.)variety Hanfeng was used as test material.Five treatments were set up by mixing and backfilling straw and soil in proportion,mixing and backfilling straw,microbial agent and decomposing agent in different proportion,and applying nitrogen fertilizer in different proportion. With no application as control,the soil physical and chemical indexes and yield before and after application were measured. The results showed that by adding corn straw,microbial agent and decomposing agent,soil organic matter and nitrogen content can be increased,pH and soil bulk density can be reduced. By applying nitrogen fertilizer,soil organic matter and pH can be reduced,and soil bulk density and nitrogen content can be increased. The changes of total phosphorus and slow-acting potassium contents in five treatments were not obvious. However,the dynamic changes of available phosphorus and available potassium in soil showed a trend of first decreasing and then increasing or gentle. The yield of black currant in all treatments was higher than that of control.
