四会沙糖桔地球化学模型及适宜种植区划研究

沙糖桔生长所需的营养元素主要来源于土壤,地质背景的不同明显影响沙糖桔的产量和品质。通过对四会沙糖桔品质、营养元素含量与土壤地球化学元素之间相关性等研究,获取影响沙糖桔生长及果实品质的根系土壤营养元素(包括MgO、CaO、S、V),从而建立沙糖桔优生地球化学模型及适宜性评价体系,并编制沙糖桔种植区划图,圈定四会沙糖桔最适宜种植范围。

Discussion on the geochemical model and region division of Shatang citrus in Sihui

The Shatang citrus get their necessary nutritional elements mainly from the soil,and the difference of geological background significantly affect the output and quality of Shatang citrus.In this paper,we focus on the correlation between the quality of Shatang citrus,nutritional elements content and geochemical elements of soil in Sihui,get the nutrient elements in root soil which impact the growth and quality of Shatang citrus(including MgO,CaO,S,V),to establish geochemical model and appropriate evaluation system of high quality Shatang citrus,as well as to draw up planting zone map and delineation of the most suitable area for planting of Shatang citrus in Sihui.
