【目的】评价攀枝花仁和区植烟土壤养分状况,为当地植烟土壤合理施肥提供科学依据。【方法】利用主成分分析、模糊数学评价土壤养分状况。【结果】新垦植烟土壤pH偏高(7.49),多年耕作土壤偏低(5.25);新垦土壤有机质较低(12.60 g/kg),多年耕作土壤较高(54.48 g/kg);研究区域土壤整体含磷量偏低(0.52 g/kg);新垦土壤全钾适中 (19.62 g/kg)、有效钾偏低(102.07 mg/kg),多年耕作土壤全钾偏低(12.38 g/kg),有效钾适中(264.67 mg/kg);两种土壤整体综合养分指数分别为0.45和0.48,养分整体偏低。【结论】该地区植烟土壤部分单一养分偏高或偏低,导致土壤整体养分不平衡,且土壤整体养分偏低。

Other Abstract

【Objective】The aim of the study was to assess the main nutrient of tobacco-planting soil at Renhe district in Panzhihua of Sichuan province,which can provide scientific basis for effective fertilization.【Method】Principal component analysis and fuzzy mathematics were used to assess the soil nutrient.【Results】Results showed that the pH was on the high side(7.49)in the newly cultivated soil, whereas lower in the mellow soil(5.25). Relative low content of organic matter was found in the newly cultivated soil(12.60 g/kg)when compared with it in the mellow soil(54.48 g/kg). In addition,the means of P in both types of soil was lower(0.52 g/kg). The means of total K was observed moderate content (19.62 g/kg)and the means of available K was relative lower(102.07 mg/kg)in the newly cultivated soil. While in the mellow soil,the means of total K was low(12.38 g/kg),but the means of available K was moderate content(264.67 mg/kg). The nutrient index of the newly cultivated soil and mellow soil were 0.45 and 0.48,respectively. The two types of soil nutrient status keep in a low level.【Conclusion】 Some of the region of soil nutrients content were excessive or insufficient,which caused the imbalance nutrients of soil nutrients supply and the entire soil nutrient were below the middle level.
