摘要 试验选择具有16a棚龄的北方大棚,以腐植酸和沸石为供试材料,采用测土施肥的试验方法,研究不同施肥处理对设施园艺土壤主要理化性状和芹菜产量的影响。结果表明:各处理相对于常规施肥处理,在土壤理化性状改进方面效果明显,各处理均能降低土壤容重,提高土壤含水量,提高土壤阳离子代换量和土壤有机质,增加土壤速效氮、磷、钾营养元素的含量。各处理与对照相比均能大幅度提高芹菜的产量。测土配方施肥+腐植酸+沸石处理对芹菜增产效果最明显。腐植酸和沸石在芹菜增产上效果显著,但是二者之间的差异不明显。测土配方施肥处理对芹菜产量提高上明显好于常规施肥处理。 The large shelf greenhouse with 16 years has been chosen for the test,humic acid and zeolite were se- lected as the main materials, and fertilization by soil test was used as testing methods, the effect on physical and chemical characters of greenhouse soil and yield of celery were studied. The results showed that the improve- ment of the treatments on physical and chemical properties was evident compared with the conventional fertiliz- er treatment, they all could reduce soil bulk density,improve soil moisture,improve soil cation exchange capaci- ty and soil organic matter, enhance content of soil available nitrogen, phosphorus, potassium. Compared with the control, the oter treatments can significantly improve the yield of celery. The best treatment on increasing celery yield was fertilization by soil test+humic acid+zeolite. The effect of humic acid and zeolite on celery yield was significantly, but no obvious difference between themselves. The effect of treatment of fertilization by soil test treatment on increasing celery yield was significantly better than conventional fertilizer treatment.
