摘要:
以喀斯特山区不同种植年限山银花及其产地土壤为研究对象，并以附近荒地土壤作为对照，通过野外调查和室内分析，测定了绥阳县不同种植年限土壤和山银花的重金属含量，并应用单因子污染指数和综合污染指数法，对土壤和山银花中重金属含量进行评价分析。明确了不同种植年限山银花及其产地土壤重金属含量水平，揭示了种植年限对土壤中重金属含量的影响及土壤重金属污染的程度，分析了土壤中Cr，Cd，As，Pb，Hg和Cu与花蕾6种重金属元素的相关关系。结果表明：随着种植年限的增加，土壤中Cu，Cr，Cd和As含量均有不同程度的增加，Hg变化不明显，Pb含量降低，总体综合污染指数为0.72，处于警戒线等级；山银花重金属平均含量和污染指数随种植年限的增加而增加，但均未超标，处于安全等级和警戒线等级；土壤中Cr，Cu，As之间存在极显著正相关性，Pb与Cr，Cu，As均存在显著负相关性，土壤中Cu，Cr，Cd和As与山银花中6种重金属元素均存在显著或极显著的正相关性，土壤中Hg和Pb与花蕾中各重金属元素存在不同程度的负相关性。本项研究对于了解种植山银花对土壤环境的效应、防控产地土壤重金属污染、保障山银花品质，具有重要的意义。
Abstract:
The samples of this study is Lonicerae Flos and site soil in different planting years in Karst mountainous area, and the wasteland soil near the research area was used as a control, by using the methods of field investigation and experiments. The heavy metal contents of the flower and site soil were determined in different planting years in Suiyang County. The soils and flower were evaluated with single factor pollution index and comprehensive pollution index. The research disclosed the effects of different planting years on heavy metals of soil and the level of environment contamination. The correlation of the 6 heavy metals (Cr, Cd, As, Pb, Hg and Cu) between soil and flower were analyzed. The findings showed that heavy metal contents of soils and flower did not exceed the standard. The contents of Cu, Cr, Cd and As are increasing with the growth years, Pb is decreasing, Hg has a little change, average value of pollution index is 0.72. The level of pollution has reached the warning rate. The average contents of heavy metals and pollution index of flower are increasing along with the planting years, but the contents did not exceed the standard, the levels of pollution are in the safe class and warning rate. There was a positive correlation among Cr, Cu and As of soil, Cr, Cu and As had a significant negative correlation with Pb in soil, Cu, Cr, Cd and As of soil were notable or significantly positive correlated with the 6 heavy metals of flower, Hg and Pb of soil had the negative correlation in different degrees with the 6 heavy metal elements of flower. This study has significance for understanding the effect of cultivating Lonicerae Flos on soil environment, protecting and controlling pollution of site soil and guaranteeing the quality of Lonicerae Flos.
