藜麦种植对内蒙古阴山北麓不同质地土壤团聚体稳定性及碳氮分布的影响
Effects of quinoa cultivation on soil aggregate stability and carbon and nitrogen distribution in different textures at the northern foot of Yinshan Mountain in Inner Mongolia
摘要
Abstract
In order to investigate the effect of quinoa cultivation on the stability of soil aggregates and the distribution of carbon and nitrogen in different textures in the northern foothills of the Yinshan Mountains in Inner Mongolia,four different textures of sandy soil,sandy loam,loamy soil and clay loam were selected in this experiment,and the mass percentages of different soil aggregates particle sizes and the contents of organic carbon and total nitrogen of each particle size were determined after planting Mengli No.6 and Mengli No.1537.The stability of soil aggregates was evaluated by mean weight diameter(MWD)and geometric mean diameter(GMD),such that the larger the values of MWD and GMD,the greater the stability of aggregates.The results showed that soil aggregate stability decreased after planting Mengli 1537 in sandy loam and loamy soil compared with that before sowing,and increased in the rest of treatments;the highest mass percentage of>2 mm particle size aggregates was 27.95%in clay loam soil after planting Mengli No.6,and the lowest mass percentage of>2 mm particle size aggregates was 12.66%in sandy soil after planting Mengli 1537,and the effect of the increase in the mass percentage of>2 mm particle size aggregates was the most significant after planting Mengli No.6.Compared with before sowing,the content of organic carbon and total nitrogen in soil aggregates of various grain sizes increased by 0.45-3.09 g·kg-1 and 0.04-0.76 g·kg-1,respectively,after quinoa was planted in sandy soil and clay loam.The study showed that planting Mengli 6 in four types of soils,and Mengli 1537 in sandy soil and clay loam could enhance the stability of soil aggregate structure,which is conducive to farmland soil improvement and to slowing land degradation in the northern foothills of Yinshan Mountain.关键词
