Abstract

In this study, Kiyomi tangor fruit tree with iron deficiency xanthation in Jinhua town, Shaohong County, Suining city, Sichuan province was studied. Different iron preparations (ferric citrate, compound amino acid ferric, ferrous sulfate, ferric humate and ferrous lactate) were applied on the surface of the leaves and soil. In contrast to water, the effects of SPAD value (relative content of chlorophyll) and fruit quality of clear fruit were detected. To compare the effect of different iron preparations on the correction of fruit tree ferriosis. The experimental results show that the effects of different iron preparations on the treatment of fe-deficient xanthosis of fruit trees were different, Among several iron preparations tested, compound amino acid iron and ferric citrate have the best treatment effect. Application of iron not only increased the relative content of chlorophyll in the leaves of fruit trees,in addition, the content of vitamin C, soluble solids and total sugar in the clear fruit was increased, and the content of total acid in the clear fruit was reduced. Effectively improve the intrinsic quality of clear fruit.
