Abstract: Abstract: A field experiment taking water as control was conducted to investigate the effects of self made calcium (small molecular organics chelated calcium), calcium nitrate and chelated with sugar alcoholspray on flesh calcium content, fruit quality and fruit coloring for peach ‘Chunmi’ during fruit enlargement and colouring period. The results indicated that all calcium spray treatments enhanced the calcium contents of leaf and flesh of peach significantly, and the calcium contents in leaves under the calcium spray during enlargement stage were much higher than other stages, the calcium contents in flesh were the highest under the calcium spray both enlargement and colouring stages. Compared with control, the foliar spray of self made calcium induced the highest calcium contents of flesh, which increased by 5.28%~10.85%. The calcium contents in leaves increased significantly among all calcium treatments, at values of 1.84 to 1.99 times of the control. Besides, allcalcium spray treatments promoted fruit quality of peach and improved fruit coloring . Compared to the control, the hardness, sugar acid ratio and polyphenol content of fruit were increased significantly by 31.03%, 61.61%, and 107.14% respectively by spraying self made calcium fertilizer during coloring stage. Judging by the total effect of spraying, self made calcium was recommended as an excellent during colouring period.
