摘要
[目的]研究浙江省绍兴市柯桥区稽东镇标准农田土壤pH现状。[方法]采取野外调查和室内分析的方法对52个土壤采样单元进行分析。[结果]该镇标准农田土壤pH平均值为4.96,属酸性,中性(6.5~7.5)的样本仅1个,占总调查样本数的1.92%,占总标准农田面积的1.78%;25.01%二等3级、8.27%二等4级田标准农田土壤处于中性或微酸性水平(5.5~7.5),三等田全部为酸性或强酸性(<5.5)土壤。[结论]建议采取施石灰、增施有机肥、推广测土配方施肥等进行改良。
[Objective]The aim was to study the status of soil pH values of standardized farmlands in Jidong Town of Zhejiang Province. [Method] The 52 soil sampling units were analyzed, by methods of field investigation and laboratory analysis. [Result] The average soil pH value of standardized farmlands in Jidong Town was 4.96, and they were acidic. Only one sample was neutral (pH6.5-7.5).It was 1.92% of total number of survey samples, and was 1.78% of the total farmland area of standards. 25.01% second-class 3 and 8.27% second-class 4 fields of standard farmland soil were in a neutral or slightly acidic (pH5.5-7.5), and all third-class field was acidic or strongly acidicsoil (pH〈5.5). [Conclusion] It was suggested that should promote soil improvement with lime, organic fertilizer, soil testing and formulated fertilization, etc.
