    摘要:

    开展以质地为关键因子的高精度植烟土壤区划,对综合提升区域烟叶品质具有现实指导意义。本研究以云南省玉溪市植烟区为研究对象,利用云南省、地市和县级土种志所记录的玉溪市土壤剖面数据为基础,并结合GIS技术和地统计学等方法,对玉溪市植烟土壤质地品质进行高精度区划。建立了玉溪市100 m级土壤质地数据池,对烟草区划的土壤关键因子土壤质地进行了科学地品质等级划分,结果表明,玉溪市适宜植烟的土壤质地品质差异较大,按土壤质地品质分级一等~五等的面积比例分别为9.87%、36.08%、11.7%、21.38%和20.97%,其中,最适宜植烟的一等土壤主要分布在峨山和华宁县,面积分别为26.2km2和25.2 km2,较适宜的二等主要分布在新平、元江和江川,面积分别为87 km2、58.6 km2和55.5 km2。不同海拔高度上的植烟土壤质地品质存在较为明显的差异,海拔1 600~2 000 m是玉溪烟叶主产区和优质植烟土壤质地主要分布区。玉溪市100 m级土壤质地空间分布图,详细程度达到村镇尺度,极大地提高了植烟区划精度及其实用性。研究结果可为优质烟叶生产及其长期规划布局和科学管理提供理论依据。

    Abstract:

    【Objective】The development of soil texture grading and zoning is of practical significance for improving tobacco quality. 【Method】Based on the soil profile data recorded in the soil species records of Yunnan province (prefecture and county), combined with GIS technology and geostatistics, this study carried out a high-precision division of soil texture and quality for a tobacco plantation in Yuxi City. A spatial database of soil texture at 100 m spatial resolution level was built, and the quality grade of soil texture of the key soil factors for tobacco zoning was scientifically divided. 【Result】The results showed that the soil texture and quality suitable for tobacco planting in Yuxi varied greatly. According to soil texture and quality, the areas of grade I to grade V were 9.87%, 36.08%, 11.7%, 21.38% and 20.97%, respectively. The most suitable grade I soil for tobacco planting was mainly distributed in Eshan and Huaning counties, with an area of 26.2 km2 and 25.2 km2, respectively. Also, suitable second class soils were mainly distributed in Xinping, Yuanjiang and Jiangchuan, with an area of 87 km2, 58.6 km2 and 55.5 km2, respectively. There were obvious differences in soil texture and quality for tobacco plantation soils at different altitudes. The main suitable tobacco plantation area was at the altitudes of 1600 ~ 2000 m. 【Conclusion】The spatial distribution of soil texture at 100 m spatial resolution level in Yuxi was as detailed as village scale, which greatly improved the precision and practicability for tobacco plantation zoning. These results can provide a theoretical basis for high-quality tobacco production, long-term zoning and scientific management of soils.
