Calcium has a variety of physiological functions, plays an important role in the process of formation of fruit quality. However the fruit calcium metabolism understanding of the law of limitations no easy calcium deficiency in the production of varieties of fruit calcium supplement ideal method. Therefore, fruit calcium absorption, operation of law to explore efficient calcium technology, has important implications for rational regulation the fruits of calcium metabolism. Fuji apple, the test for the test material, the use of the isotope atoms tracer absorption of calcium in the tree and fruit, operation research, explore new calcium technology processing and field trials, the main results are as follows: different growth stages of absorption of calcium in the various organs assign different young fruit is allocated mainly in fruits and shoots, respectively, of the total calcium content of 34.79%, 11.31%; enlargement period is mainly distributed in leaf blade, or 44.91% of the total amount of calcium . 2 different growth stages of absorption of calcium in the presence of various organ morphology obvious differences, young fruit mainly exists in the form of active calcium; enlargement of the non-active calcium form improved significantly this change is very obvious, especially in the pedicel and fruit Taichung . IAA morphological change in the presence of calcium in the stalk, so that the water-soluble calcium, calcium and pectin 1.88,1.30 times were increased to 76.51%, thus the increase in the calcium content of the fruit. A 3 of the fruit sets Fushao and fruit stage different order bits of leaves of fruit for calcium capacity, the order is: if the sub slightly on the 1-4 leaf> fruit station rosette at the top 1-4 leaf> fruit station -4 bit blade> the fruit sets Fushao 5-8 leaves. The blades on fruit calcium supply to follow the principle of proximity, away from the leaves of the fruit of the fruit for calcium is weak. 4 flowers before 15d, after flowering, 15d; 15,30 days after flowering; 105,120 days after flowering; preharvest 35,20 d four treatment periods combination of injection of calcium citrate can significantly increase the calcium content of the fruit, but to spend before 15d, after flowering 15d combination lose calcium effect of the treatment period. Calcium citrate and other substances with the processing, the best fruit calcium content increased by 104.83% with the use of calcium citrate and IAA. The effect of calcium intake of calcium the foliar calcium in calcium amino acid additional IAA, B, Zn treatment, the calcium content in the fruit can be increased by 94.61%. 5 lose calcium treatment to reduce the sugar and acid content of the fruit, fruit firmness, but this effect is related to the treatment period, which flowers before the 15d, after flowering, 15d, and mining before 35,20 d treatment can significantly improve the calcium content of the fruit increase fruit firmness, fruit sugar and acid content was less affected.
