摘要:

对沪郊蔬菜主产区域的165个土壤样品进行主要养分含量测定与统计分析,评价菜地土壤主要肥力指标和土壤pH。结果表明,沪郊蔬菜主产区土壤平均pH 6.82,不同涉农区土壤pH呈现较大差异;土壤有机质平均含量相对丰富,绝大部分土样中碱解氮、有效磷和速效钾含量都处于Ⅰ级水平;土壤可溶性盐平均含量3.5 g/kg,达到轻度盐渍化水平。

关键词: 菜地, 土壤养分, 分析与评价

Abstract:

The contents of main nutrients of 165 soil samples from main vegetable producing areas in the suburbs of Shanghai were measured and statistically analyzed, and major fertility indexes and soil pH of vegetable fields were evaluated. The results show that the average soil pH in the main vegetable producing areas in the suburbs of Shanghai is 6.82, and there are great differences in soil pH in different agricultural areas; the average content of soil organic matter is relatively rich, and the content of alkali-hydrolyzed nitrogen, available phosphorus and available potassium in most soil samples are at the level of grade I; the average content of soil soluble salt is 3.5 g/kg, reaching the level of mild salinization.

Key words: vegetable field, soil nutrients, analysis and evaluation
