摘要
对荆州市郊菜地土壤和粮田土壤进行调查取样,测定了容重、pH值、有机质、全氮、碱解氮、速效磷和速效钾等项养分含量。菜地土壤比粮田土壤肥力明显改善,且随种菜年限延长呈提高趋势。但菜地土壤速效钾含量呈降低趋势。
An investigation on vegetable farm soil of Jingzhou City suburbs was made. Soil volume weight, pH, organic matter, total nitrogen, alkalihydrolysis nitrogen, rapid available phosphorus and potassium were determind respectively. The results showed that the fertility of vegetable plot were significantly higher than that of crop fields and increased with the time of vegetable cultivation. Compared with the crop fields, the amount of rapid available potassium decreased.
