Zaoxiang pomelo magnesium deficiency repair method

The invention relates to a Zaoxiang pomelo magnesium deficiency repair method. The method comprises the following steps that 1, one-time basal application is conducted before germination of Zaoxiang pomelos, wherein basal application includes three-nutrient compound fertilizer and magnesium containing fertilizer; 2, leaf sample collecting and content measurement are conducted, wherein leaf samplesare collected, and the chlorophyll content and element content of the leaf samples are measured; 3, fruit sample collecting and quality measurement are conducted, wherein fruit samples are collected,and the total sugar content, soluble solid content, total acid content, Vc content, juice yield and edible rate of the fruit samples are measured; 4, data denoising is conducted; 5, fertilizer supplementing is conducted, wherein according to the determined element content and fruit quality data, whether or not the magnesium content reaches a good value is judged, and whether or not magnesium fertilizer needs to be supplemented is determined. The method has the advantages that leaf yellowing, winter old leaf fall off and too small fruits which are caused by magnesium deficiency can be effectively treated; the magnesium content of a Zaoxiang pomelo tree body is increased; the single fruit weight, yield and quality of the Zaoxiang pomelos can be significantly improved, and the appropriatelyapplied magnesium fertilizer types and the magnesium fertilizer and medium and micro nutrient element combining application technology are provided.
