Abstract
It is widely researched and confirmed that calcium is an essential element of fruit quality. By spraying active calcium on the surface of the leaves of three kinds of navel orange trees-Pengna, Newher, and Navel 2 - 8 and analyzing the effects of active calcium on the quality of these oranges statistically, we find that active calcium remarkably increased the fresh weight, the content of soluble carbohydrate and total sugar; it also improved the fruit shape.
