Abstract
During the development of grape fruits,the effects of fertilizing calcium on the fruit qualities and the resistance to S.ampelinum were studied.The method of application of Ca included leaves spraying,soil-fertilizing,and the colligation of leaf-spraying and soil-fertilizing.The results showed all the treatments increased more or less the content of Ca in the fruits.Of all the treatments,the spraying of 1.00%(W/V)Ca(NO3)2 and 1.25%(W/V)Ca(NO3)2 combined with 1.00%(W/V)CaCl2,could increase the content of Ca significantly.The content of Ca was negative correlation with the incidence of disease and the disease index in grape fruit.The N/Ca was positive correlation with the incidence of disease and the disease index in grape fruit.Ca could promote the grape fruit's resistance to S.ampulinum.
