Abstract:

通过盆栽试验研究了有机肥与无机肥配施对菠菜产量、品质及土壤供氮特性的影响。结果表明,收获时菠菜生物量由大到小依次为处理4(5%(占施氮量百分比)尿素与95%有机肥配施)、处理5(10%尿素与90%有机肥配施)、处理3(有机肥)、处理2(无机肥)、处理1(不施肥);植株氮累积量以处理5最多,其他处理趋势与生物量相同。收获时,植株维生素C含量依次为处理4、处理3、处理5、处理2、处理1,并且所有处理菠菜可食用部分硝酸盐含量均达到直接食用标准(小于432mg.kg-1);无机肥处理比有机肥处理矿质态氮释放速度快,有机无机肥配施处理能更好地调节土壤氮素的释放;有机无机肥配施处理与有机肥处理能增加土壤微生物量碳,且增加幅度大于单施无机肥处理。
