Abstract: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 4720hm2, generally suitable planting area is 7793hm2, and not suitable planting area is 3480hm2. 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.
