摘要
于2021年在云南陆良县选取分布于7个植烟乡镇的31处植烟地块,采用面上取样和模糊数学隶属函数模型等研究方法,比较了不同前茬作物下植烟土壤理化特性差异,初步评价了土壤肥力质量,并建立了其与烟叶质量的相关性。结果表明,绿肥为前茬作物的土壤全氮、速效钾、有机质、全钾含量与土壤阳离子交换量均最高,马铃薯为前茬作物的土壤氯含量较高。各处理土壤肥力综合评价得分值为0.589~0.763,绿肥为前茬作物的得分最高,其余依次为玉米、撂荒和马铃薯,对土壤肥力影响最高的因子为氯离子和有效磷含量。结构方程模型和相关性分析表明,前茬作物通过直接影响土壤理化性质而改变土壤肥力,进一步影响烟叶化学性质,最终影响烟叶质量。
In 2021,selecting 31 tobacco-planting plots distributed in seven tobacco-planting townships in Luliang County,Yunnan province,surface sampling and fuzzy mathematical membership function model were used to compare the differences in physical and chemical properties of tobacco-planting soil with different previous cropping,preliminatively evaluate the soil fertility quality,and the correlation between soil fertility and tobacco leaf quality was established.The results showed that the contents of total nitrogen,available potassium,organic matter,total potassium and cationic exchange capacity of the soil with green fertilizer as the previous crop were the highest,and the content of chlorine in the soil with potato as the previous crop was higher.The scores of the comprehensive evaluation of soil fertility of each treatment were 0.589 to 0.763,with green fertilizer as the previous crop scoring the highest,followed by corn,uncultivated and potato.The factors that had the highest influence on soil fertility were chloride ion and available phosphorus content.Structural equation model and correlation analysis showed that the previous crop changed soil fertility by directly affecting soil physicochemical properties,further affecting tobacco chemical properties,and finally affecting tobacco quality.
