| 摘 要： | 本文研究了在目前农田大量施用化肥及有机肥的情况下南京市南郊蔬菜地土壤pH和盐分含量的变化。研究结果表明:在露天农田土壤pH略有上升的基础上,南京市南郊大棚蔬菜地土壤的pH值比露天农田下降了约0.30~0.87,比第二次土壤普查时的露天蔬菜地下降了约0.12~0.52;同时,大棚蔬菜地土壤盐分累积也较为严重,主要表现为NO3-在土壤中的大量累积。

| Abstract: | Change in pH and salinity of the vegetable soil in the southern suburbs of Nanjing was investigated. The results showed that pH of the soil under plastic greenhouse reduced by 0.30 ~ 0.87 unit, compared to that of the soil in open vegetable fields. The salinity of the soil in plastic greenhouses rose drastically, which largely resulted from increase in nitrate. |
