1) The original source of soil
土壤母质来源
1.
The original source of soil,the physiognomy characters of farm land,the forming soil model and 4 main features of soil were analyzed systematically from some aspects,such as the geographical background,the physiognomy characters,the characters of coming into soil,and the inflow characters in space distributing area from the rock efflorescence to becoming soil.
从岩石风化至成壤过程在空间上分布区域的地质背景、地貌特征、成土成壤特征以及成土成壤物质的流入特点等方面,系统地进行了土壤母质来源、农用地地貌特征、成土成壤单元类型、"土壤四大特性"等分析,指出封闭型、类封闭型成土成壤单元是名特产品产出的空间条件;研究区内农用地的土壤母质来源地层单一,且未经过远距离搬运,保持了岩层岩石成土矿物的特性,是形成名特农产品麦萝品质的特色之本。
