调查分析了慈溪市土壤肥力现状,并与第二次土壤普查(1981年)情况作了比较。表明慈溪市土壤有机质和碱解氮含量不高,速效磷较丰富,但存在着不平衡性,速效钾相对较低,特别是旱地土壤;滨海盐土和水稻土分别缺乏微量元素锌和硼;滨海盐土及部分设施栽培土壤的盐渍化威胁着作物生长。根据上述情况,提出了合理施肥及改良利用的建议。
The status of soil fertility in Cixi City was investigated and compared with that of the second soil survey (1981). It shows that the content of soil organic matter and alkali-hydrolyzable nitrogen is not high and available phosphorus is rich in Cixi City, but there is imbalance and the content of available potassium is relatively low, especially in dryland soil. The coastal saline soil and paddy soil are deficient in trace element zinc and boron respectively. Salinization of saline soils and part of cultivated soils threatens crop growth. According to the above situation, put forward the suggestion of rational fertilization and improvement of utilization.
