摘要
为了研究半夏产地土壤性状,作者采集贵州半夏产地土壤进行理化分析,其结果表明:半夏产地土壤容重在0.76～1.37g/cm3之间,平均值为1.05g/cm3,土壤容重较小,土壤熟化程度较高;土壤含水量在21.56%～28.98%之间,平均25.58%,土壤pH值大部分适宜半夏生产。有机质含量地区差异较大,土壤营养元素中钾素充足,氮素和磷素含量低,应采用测土配方施肥技术,合理施肥。
In order to study the soil characteristics of Pinellia ternata, soils in Guizhou Pinellia ternata origin were collected for analysis. Results showed that soil bulk density was between 0.76 g/cmz and 1.37 g/cm3, with the average of 1.05 g/cm3, suggesting small average soil bulk density and higher degree of maturation of soil. Soil moisture content was between 21.56 % and 28.98 %, with the average of 25.58 %. Most soil pH value was suitable for the production of Pinellia ternata. nitrogen and phosphorus, which could be Organic matter were different in areas, with adequate potassium and low adjusted by testing soil for rational fertilization.
