| 摘 要： | 研究贵州地区辣椒地土壤的理化性质,结果表明,各地土壤除非毛管孔隙度、全N、水解N、全P、速效K、有机质含量达到统计学上的差异水平外,容重、比重、总孔隙度、毛管孔隙度、自然水含量、缓效K、pH值均无显著差异。花溪茅草土壤非毛管孔隙度为37.37%,极显著高于其他地区,但土壤有效P含量最低,为6.5mg/kg。都匀土壤全N、水解N、有效P、有机质含量最高,分别为0.22%、1 78.12mg/kg、30.0mg/kg、5.80%。花溪果落土壤全P、速效K含量最高,分别为0.1 9%和950mg/kg。毕节土壤非毛管孔隙度、全N、全P、含量最低,分别为8.5%、0.13%、0.05%。遵义土壤水解N、有机质含量最低,分别为53.81mg/kg、1.61%。天柱土壤速效K含量最低,为1 60mg/kg。花溪茅草和花溪果落由于同属党武乡,性质相近。

| Abstract: | This paper researched the physical and chemical properties of soil under different region of capsicum in Guizhou. The result indicates that regional soil＇s non-capillary porosity, the total N, hydrolysis N, the total P, available K, organic content reach the difference level in statistics, but the bulk density, proportion, total porosity, capillary porosity, natural water content, inavalable K, hydrogen ion index have not a remarkable difference. Non-capillary porosity of soil in the region of Maocao is 37.37%, which is higher than other areas extremely notably.But its effective P of soil has the lowest content of 6.5mg/kg. The total N, hydrolysis N, the total P, available K, organic content are 0.22%, 178.12mg/kg, 30.0mg/ kg, 5.80% respectively in Duyun. The total P, available K are 0.19% and 950mg/kg respectively in Guoluo. Non-capillary porosity, the total N, the toyal P are most low, which is 8.5%, 0.13%, 0.05% respectively in Bijie. The hydrolysises N, organic content are most low in Zunyi, which is 81mg/kg, 1.61% respectively.Tianzhu soil＇s available K has the lowest content, which is 160.mg/kg. |
