| 摘 要： | 为探究不同施肥处理对芹菜农田土壤理化性状及产量的影响,以‘文图拉’芹菜为供试作物,设置单施化肥(T)、有机肥配施化肥(YTF1/2)和全量有机肥(YTF)3个处理。结果表明,在不同施肥处理下芹菜农田土壤的理化性质和芹菜产量发生了变化,其中变化最为明显的土壤指标有土壤容重、孔隙度、饱和导水率、碱解氮和有效磷。2019年,YTF处理较T处理显著降低土壤容重13.16%,增加土壤孔隙度10.72%,提升饱和导水率20.73%。YTF1/2处理较T处理显著提升土壤碱解氮和有效磷含量15.8%和19.6%。2020年,YTF处理较T处理显著降低土壤容重10.71%,增加土壤孔隙度8.23%,提升饱和导水率17.76%。YTF1/2处理较T处理显著提升土壤碱解氮和有效磷含量16.18%和12.91%。与T处理相比,YTF1/2和YTF处理均能提高芹菜产量。2019年,YTF1/2处理芹菜产量最高,为97984 kg/hm2,与T和YTF处理相比分别提升产量2.65%和22.83%。2020年,YTF1/2处理芹菜产量最高,为93750 kg/hm2,与T和YTF处理相比分别提升产量25%和13.64%。总体来看,有机肥配施化肥效果最优,可在试验开展地区芹菜种植中推广应用。

| Abstract: | To explore the effects of different fertilization treatments on soil physical and chemical properties and yield of celery, the study used ‘Ventula’ celery as the test material, and conducted three treatments: single application of chemical fertilizer (T), organic fertilizer combined with chemical fertilizer (YTF1/2) and total organic fertilizer (YTF). The results showed that different fertilization treatments had changed the soil physical and chemical properties and celery yield, and the most obvious changes were found on soil bulk density, porosity, saturated water conductivity, alkali-hydrolyzed nitrogen and available phosphorus. In 2019, compared with T treatment, YTF treatment significantly reduced soil bulk density by 13.16%, increased soil porosity and saturated water conductivity by 10.72% and 20.73%, respectively. Compared with T treatment, the content of soil alkali-hydrolyzed nitrogen and available phosphorus in YTF1/2 treatment were significantly increased by 15.8% and 19.6%, respectively. In 2020, compared with T treatment, YTF treatment significantly reduced soil bulk density by 10.71%, increased soil porosity by 8.23% and soil saturated water conductivity by 17.76%. Compared with T treatment, YTF1/2 treatment significantly increased the content of soil alkali-hydrolyzed nitrogen and available phosphorus by 16.18% and 12.91%, respectively. Compared with T treatment, both YTF1/2 treatment and YTF treatment increased celery yield. In 2019, the celery yield of YTF1/2 treatment was the highest, which was 97984 kg/hm2, 2.65% and 22.83% higher than that of T treatment and YTF treatment, respectively. In 2020, the celery yield of YTF1/2 treatment was the highest, which was 93750 kg/hm2 and increased by 25% and 13.64% compared with that of T treatment and YTF treatment, respectively. In general, organic fertilizer combined with chemical fertilizer had the best effect, and could be popularized in local celery cultivation. |
