基于土壤地球化学特征的茶叶种植适宜性评价分析——以日照巨峰镇为例

Analysis on Tea Planting Suitability Based on Soil Geochemical Characteristics--Setting Jufeng Town in Rizhao as an Example

为响应国家乡村振兴的号召,进一步提升提高日照市巨峰镇土地质量地球化学调查成果的科技转化潜力,本文综合运用层次分析法、SPSS软件系统聚类法、内梅罗综合指数法、变异系数法等方法,在查明研究区土壤地球化学背景值、评价研究区的土壤肥力、评价研究区的茶叶生化品质、研究研究区茶叶生化特征的影响因素的基础上,对研究区内土壤的茶叶宜种性进行综合评价。结合研究区的生产建设实际及已有茶园分布情况,将研究区大致划分为最适宜种植区、一般适宜种植区和不适宜种植区三大类。其中适宜种植区4720hm^(2),一般适宜种植区7793hm^(2),不适宜种植区3480hm^(2)。本次工作为研究区茶叶种植区扩建提供了科学指导,进一步提升了土地质量地球化学调查成果的科技转化水平。

In response to the call of national rural revitalization,in order to further enhance scientific and technological transformation potential of the results of geochemical survey of land quality in Jufeng town of Rizhao city,aiming at Jufeng green tea,by using analytic hierarchy process method,SPSS software system clustering method,Nemero comprehensive index method,coefficient of variation method comprehensively,on the basis of identifying the background value of soil geochemistry in the study area,evaluating soil fertility in the working area,evaluating the biochemical quality of tea in the working area,and studying the influencing factors of tea biochemical characteristics in the working area,a comprehensive evaluation of tea suitability in the study area has been carried out.Combining with the actual production and construction of the study area and the distribution of existing tea gardens,the study area is roughly divided into three categories,they are the most suitable planting area,the general suitable planting area and the unsuitable planting area.Among them,suitable planting area is 4720hm^(2),generally suitable planting area is 7793hm^(2),and not suitable planting area is 3480hm^(2).This study will provide scientific guidance for the expansion of tea planting area in the study area,and further improve the level of scientific and technological transformation of land quality geochemical survey results.
