通过野外调查与室内分析相结合的方法 ,研究了杭州市郊主要菜园土壤锌营养状况 ,并对其与土壤有机碳的关系作了探讨 .取样分析结果表明 :调查区域菜园土壤全锌含量在 75.5～ 30 2 .0 mg/ kg之间 ,平均为 ( 168.1± 58.0 ) mg/ kg;有效锌含量在 0 .78～ 9.15mg/ kg之间 ,平均为 ( 3.90± 2 .0 1) mg/kg.同时还发现 ,菜园土壤有效锌含量与全锌含量呈极显著正相关 ,菜园土壤有效锌的供给是以全锌量为基础的 .全锌含量与总有机碳和易氧化有机碳含量均呈极显著正相关 ;有效锌含量也与总有机碳和易氧化有机碳含量呈极显著正相关 .这表明施用有机肥料可能是菜园土壤锌营养的重要来源之一
Through field investigation and indoor analysis, the status of zinc nutrition of main garden soil in suburbs of Hangzhou was studied, and the relationship between soil zinc and soil organic carbon was discussed. The results of sampling analysis showed that the total zinc content of the vegetable garden soil in the survey area was between 75.5 ~ The average zinc content was between 0.78 and 9.15 mg / kg, with an average of (3.90 ± 2.01) mg / kg between 30 2 .0 mg / kg and 168.1 ± 58.0 mg / kg on average. At the same time, it was also found that there was a significant positive correlation between available zinc content and total zinc content in vegetable garden soils, and the available zinc content in vegetable garden soils was based on total zinc content.The total zinc content, total organic carbon Significantly positive correlation between available zinc and organic carbon and organic carbon content was significantly positively correlated.This shows that the application of organic fertilizers may be one of the important sources of soil zinc nutrition
