本文利用数字图像分析方法,研究了新葡萄园和老葡萄园在常规耕作和短期免耕下土壤孔隙结构的差异。结果表明:常规耕作和短期免耕土壤在孔隙结构上具有较为明显的差异。与短期免耕相比,常规耕作土壤具有较多规则的小土粒,孔隙面积较大,其小孔隙比重较高。新葡萄园常规耕作和短期免耕土壤结构之间的上述差异相对弱于老葡萄园土壤。
In this paper, the digital image analysis method was used to study the differences in soil pore structure between conventional and short-term no-till in new and old vineyards. The results showed that there were obvious differences in pore structure between conventional and short-term no-till soil. Compared with short-term no-tillage, conventional tillage soil has more regular small soil particles, larger pore area and higher specific gravity of small pores. The above differences between conventional and short-term no-till soil structures in the new vineyard are relatively weaker than in the old vineyard soil.
