摘　　要：为明确硝酸钙泥对土壤的改良效果,采用盆栽试验研究了硝酸钙泥与泥炭和无机肥配施对石灰性褐土和菜园土的土壤pH值、含盐量、有机质、全氮、速效磷和速效钾的影响。结果表明,从土壤pH值和含盐量改变效果来看,泥炭∶钙泥为1∶6的施肥处理施用效果最好;从土壤有机、无机养分含量来看,泥炭∶钙泥为4∶3的施肥处理施用效果最好。不同施肥处理可以改善土壤酸碱度,增加土壤含盐量,提高有机、无机养分含量,因此,硝酸钙泥可与泥炭和无机肥配置成复混肥料,从而实现农业资源化利用。To study the effect of calcium nitrate residue on soil.Use potting experimental to study under the calcium nitrate residue and cooperate with peat and inorganic fertilizers to influence on the pH value,content of salt,organic matter,total nitrogen,available phosphorusin and available potassium of calcareous soil and vegetable garden soil.The results show that the soil pH value and salinity change,the effect of the peat∶calcium mud = 1∶6 best fertilizer processing application effect;from the point of soil organic and inorganic nutrients content,peat∶calcium mud = 4∶3 fertilization treatment applied effect is best.It can improve the soil pH value under different fertilizer treatment,increase the soil salt content,improve the organic and inorganic nutrients content.Therefore,calcium nitrate with peat and inorganic fertilizer can be configured to mud compound fertilizer material implementation of agricultural resource utilization.
