摘  要：
以开封市郊区露地菜田和蔬菜大棚为研究对象,分析了不同种植年限下,露地菜田和蔬菜大棚之间的耕层土壤酸碱度以及速效养分的差异。结果表明:5年种植年限大棚土壤pH值比2年限大棚土壤降低了0.4个单位;5年种植年限大棚土壤碱解氮含量比露地种植高42.4%;2年限大棚土壤有效磷含量比露地土壤高4.6倍;土壤速效钾含量都达到国家一级标准,无明显差异;5年限大棚土壤有机质比露地土壤高13.6%。有机质含量与土壤碱解氮含量呈极显著正相关关系,与pH值呈显著负相关关系。

摘  要：
Taking vegetable field and vegetable greenhouse as research objects in the outskirts of Kaifeng, the differences of soil available nutrients and soil pH values in the surface soil between the vegetable field and vegetable greenhouses in different cultivating years were analyzed. The results showed that pH value in 5 years greenhouse decreased by 0.4 unites compared with that of 2 years greenhouses. AHN content in 5 years soil increased by 42.4% compared with that of open-land field soil. AP content in 2 years soil was 4.6 times higher than that of open-land field soil. AK content in all the subjects reached national primary standard, showing no significant difference. Organic matter content was not abundant in all the subjects, and that in 5 years soil was 13.6% higher than that of open-land field soil. While the content of organic matter was significantly positively correlated with the AHN content, and had a significant negative correlation with pH value.
