摘要: 采用温室盆栽试验,研究复混肥料中不同氮素形态配比对2种土壤玉米苗期生长及氮肥利用效率的影响。结果表明,在黑土上,施用酰胺态氮为单一氮素形态的复混肥料时,玉米的出苗率明显下降;而用部分铵态氮替代酰胺态氮后制成的混合态氮和由铵态氮与硝态氮构成的复混肥对玉米的出苗率影响较小;不同氮素形态配比的复混肥对潮土上生长的玉米出苗影响较小,各处理的出苗率可达到90%以上。生长45d玉米苗的地上和地下部的生物量,在黑土上均以全酰胺态氮的配方最高,地上部干重较其他配方增加10%左右;而在潮土上则以铵态氮与硝态氮配方的效果最好,铵态氮和酰胺态氮混合的配方在2种土壤上均较差。玉米苗期的氮素累积量及氮肥利用率,在2种土壤上均以在复混肥料中含有适当比例硝-铵态氮的配方最高。

Abstract: A pot experiment was carried out to investigate the effect of compound fertilizers with different nitrogen forms on maize seedling growth in different soils.The results showed as follows:Maize grown in the treatment of compound fertilizer containing urea alone had significantly lower germination rate than the maize receiving mixed CO(NH2-N/NH4+-N or mixed NO3--N/NH4+-N in compound fertilizers in Udic Isohumisols.However,there was no significant affect of nitrogen forms on maize germination rate in Udic Cambosols.Nitrogen forms in compound fertilizer affected biomass accumulation of maize too,and the highest dry weight of shoot and root was found in the plants supplied with compound fertilizer containing 100% urea nitrogen in Udic Isohumisols,and mixed nitrate and ammonium in Udic Cambosols.It was shown that enhancement of NO3--N/NH4+-N in compound fertilizer could increase nitrogen accumulation and nitrogen use efficiency of maize in both of the soils.
