摘要
为探究蓝山植烟土壤养分变化特征以及对蓝山各植烟土壤类型的适宜性进行评价,分别于2000年和2020年在蓝山烟区采集土壤样品并选取有机质、全氮、有效磷、有效磷、有效硫、有效锌、有效铁、有效锰和有效硼9个土壤肥力指标,采用主成分分析和模糊数学方法建立了植烟土壤综合肥力评价模型。结果表明,蓝山县植烟土壤各土壤肥力指标间相关性趋势中,75.00%标本数量未呈现显著变化,维持原有关联特征,2000年和2020年蓝山县土壤综合肥力指数分别为0.349和0.458,2020年较2000年增幅分别为9.52%和31.23%,总体呈升高趋势,更有利于优质烟叶生产。综上,在烟叶生产过程当中,该区应根据土壤养分的丰缺状况平衡施肥。
To explore the variation characteristics of soil nutrients in the tobacco-growing soils of Lanshan and evaluate the suitability of different tobacco-growing soil types in Lanshan.soil samples were collected from the Lanshan tobacco-growing area in the years 2000 and 2020.Nine soil fertility indicators were selected,including organic matter,total nitrogen,available potassium,available phosphorus,available sulfur,available zinc,available iron,available manganese,and available boron.A comprehensive soil fertility evaluation model for tobacco-planting soils was established using principal component analysis and fuzzy mathematics methods.The results showed that,among the correlation trends of various soil fertility indicators of tobacco-growing soils in Lanshan County,75.00%did not exhibit significant changes and maintained the original correlation characteristics.The comprehensive soil fertility indices of Lanshan County in 2000 and 2020 were 0.349 and 0.458 respectively.representing increases of 9.52%and 31.23%in 2020 compared to 2000.Overall,the soil fertility showed an upward trend,which was more conducive to the production of high-quality tobacco leaves.In conclusion,during the tobacco leaf production process in this area,balanced fertilization should be carried out according to the abundance and deficiency of soil nutrients.
