摘要(Abstract):

该研究运用主成分分析法(PCA)结合各土壤肥力指标的Norm值以及指标间的相关系数建立了湖北麻城菊花种植区土壤肥力评价的最小数据集(MDS);运用雷达图直观反映单项指标的肥力水平;利用综合指数模型计算土壤肥力质量指数(SFQI),并进行聚类分析。结果表明:有机质、全磷、速效磷、有效镁、以及有效铁5个指标组成MDS;雷达图显示两个种植区土壤中速效磷和有效铜肥力差异最大,有效铁差异最小;黄土岗镇除有效锰肥力水平大于福田河镇,其余均低于福田河镇;以MDS指标在全量数据集(TDS)指标所在的主成分的贡献率为权重计算的SFQI值的敏感度最大,MDS可以较好的替代TDS;SFQI-MDS为0. 353~0. 833,均值0. 604,变异系数为22%; SFQI-MDS值聚类结果可将土壤肥力分为4个等级,Ⅰ级(0. 727~0. 833)为优,占25. 0%,Ⅱ级(0. 615~0. 681)为良,占29. 2%,主要分布在福田河镇,Ⅲ级(0. 494~0. 589)为中等,占29. 1%,Ⅳ级(0. 353~0. 419)为差,占16. 7%,主要分布在黄土岗镇。麻城菊花种植区福田河镇土壤肥力优于黄土岗镇。建议麻城菊花在种植中补施硼肥、钾肥,适量增加磷肥、镁肥和氮肥施用量,同时加大有机肥施用量,提升土壤肥力,改良土壤理化性状。
A minimal data set( MDS) for soil fertility evaluation of Chrysanthemum plantation areas of Macheng city was established by principal component analysis( PCA) combined with Norm values of soil fertility indices and correlation coefficients among indices. A radar map was used to visually reflect the fertility level of individual indicators. Then,the comprehensive index model was used to calculate the soil fertility quality index( SFQI),and the values of SFQI was used to cluster,and the results showed that MDS was composed of five indicators: organic matter( OM),total phosphate( TP),available phosphorus( Av P),available magnesium( Av Mg) and available ferrum( Av Fe). Radar maps showed that the fertility of available phosphorus( Av P) and available copper( Av Cu) was mostly different in the two town,and the fertility of available ferrum( Av Fe) is smallest different. Except for the effective manganese( Av Mn) fertility level of Huangtugang town was higher than that of Futianhe town,the rest were lower than that of Futianhe town. Through analysis,the sensitivity of SFQI value calculated by taking the contribution rate of MDS index in the principal component of the whole data set( TDS) as the weight was the highest,MDS could better replace TDS. The value of SFQI-MDS ranged from 0. 353 to 0. 833,with an average value of 0. 604 and a coefficient of variation of 22%. The results of SFQI-MDS clustering showed that soil fertility could be divided into four categories: grade Ⅰ( 0. 727-0. 833) was superior,accounting for 25. 0%,grade Ⅱ( 0. 615-0. 681)was good,accounting for 29. 2%,mainly distributed in Futianhe Town,grade Ⅲ( 0. 494-0. 589) was medium,accounting for29. 1%,and grade Ⅳ( 0. 353-0. 419) was poor,accounting for 16. 7%,mainly distributed in Huangtugang town. Soil fertility of Futianhe town was better than that of Huangtugang town. It is suggested that boron fertilizer and potassium fertilizer should be supplemented to Chrysanthemum morifolium in production practice,and the amount of phosphate fertilizer,magnesium fertilizer and nitrogen fertilizer should be increased appropriately. At the same time,the amount of organic fertilizer should be increased to enhance soil fertility and improve soil physical and chemical properties.
