Abstract:

Taking the celery as material,the effect of unfermented potato residue，potato residue organic fertilizer，as well as N-P-K compound fertilizer on soil structure and quality and yield of celery were studied in the open field,with no fertilizer as control.The results showed that the content of potato residue organic fertilizer，application of organic matter in the soil than the control increased 2.58 g/kg，total nitrogen increased 0.06 g/kg，total phosphorus increased 0.03 g/kg，available nitrogen，available phosphorus increased 2.12 mg/kg,10.11 mg/kg respectively，42.75 mg/kg of available potassium，soil and total salt and pH had no significant effect.Application of potato residue organic fertilizer make celery plant height，chlorophyll content，dry weight and yield were significantly higher than those of control and unfermented potato residue，chlorophyll content and dry weight were significantly higher than that of N-P-K compound fertilizer，organic fertilizer that potato slag had good effect，and it could promote the growth of celery.
