| 摘 要： | IFC化肥增效剂在盆栽小白菜上的应用试验表明:与单独施用碳铵处理相比,施用碳铵 IFC化肥增效剂可使小白菜鲜重增加8.97%(P＜0.01),干重增加3.45%(P＜0.05),吸氮总量增加8.70%(P＜0.01),NO-3-N含量降低30.10%(P＜0.01),但含氮率无明显变化.IFC在小白菜上的应用效果好于常用氮肥增效剂双氰胺.适量施用IFC化肥增效剂使土壤氨化强度略有增加,能在一定程度上抑制土壤反硝化作用,但对土壤微生物生物量未产生明显影响. |

| Abstract: | A pot experiment was carried out to research effects of IFC,a fertilizer synergist,on pak choi.Results show that compared with application of carbon-ammonium fertilization only,the addition of IFC improved the growth of Brassica campestris ssp.Chinensis by increasing fresh yield by 8.97%(P<0.01),dry weight by 3.45%(P<0.05),and nitrogen accumulation by 8.70%(P<0.01),and decreasing NO-3-N content by 30.10%(P<0.01),but did not have much effect on nitrogen content.The effect of IFC is much better than dicyandiamide(DCD),a commonly used N fertilizer synergist.Application of IFC at a proper rate can slightly accelerate ammonification and inhibit denitrification in the soil,and yet does not affect much microbial biomass in the soil. |
