选择赤峰市敖汉旗两种主要土壤(风沙土、栗钙土)为研究对象,采用Mastersizer 3000激光粒度分析仪测定不同类型土壤0~100 cm深度范围内的土壤机械组成(粘粒、粉粒及砂粒)。研究结果表明:相同土壤类型不同土层的机械组成基本相似,不同土壤类型相同土层的土壤粒径比例不同;不同土壤类型的土壤粒径含量总体表现为砂粒:风沙土>栗钙土,粘粒、粉粒为:栗钙土>风沙土。研究结果旨在为合理评价当地土壤结构和科学利用土地提供科学依据。
Two main soils (aeolian sandy soil and chestnut soil) were selected as the research objects in this paper. The mechanical composition of soils (clay, silt and soils) in the depth of 0 ~ 100 cm of different types of soils was determined by Mastersizer 3000 laser particle size analyzer And sand). The results show that: the mechanical composition of different soil layers with the same soil types are basically similar, the different soil types with the same soil layers have different proportions of soil particle sizes; the soil particle sizes of different soil types are generally characterized by sand grains: aeolian soil> Granules, powder are: chestnut soil> windy soil. The results are intended to provide a scientific basis for the rational evaluation of the local soil structure and the scientific use of the land.
