摘要
调查了昆明烟区9个土壤剖面,并对其耕层进行土壤理化性状分析。结果表明,9个剖面分别由中生代紫色砂页岩、碳酸岩、第四纪冲积母质、坡(残)积母质、第四纪湖积物风化母质发育而成。根据土壤特性,按照《中国土壤系统分类(修订方案)》,9个剖面分属4个土纲、5个土类、5个亚类。剖面构型共有3种:耕作层(A)—犁底层(P)—心土层(淀积层B)—母质层(C)、耕作层(A)—心土层(淀积层B)—母质层(C)、耕作层(A)—母质层/母岩层(C/D)。剖面耕作层厚度为17-33cm,土体厚度差别较大,最薄的仅18cm,最厚的竟达100cm。
In Kunming area, nine soil profiles were investigated and the physical and chemical character of cultivated soil was analysed. The results showed that these profiles developed from Mesozoic purple sandshale and carbonatite, quaternary alluvial parent materials, deluvial or eluvial parent materials and lake weathering parent materials. According to Chinese Soil Taxonomic Classification （Revised Proposal）, nine soil profiles respectively belonged to 4 soil orders, 5 soil great groups and 5 soil subgroups. The profile form included A-P-B-C, A-B-C and A-C/D, whose cultivated soil thickness was 17-33 cm and the whole soil thickness was 18-100 era.
