Abstract

Field experiment and investigation about the effect of Calcium application were carried out.The result showed that calcium application can reduce fruit cracking and enhance the hardness;proper ratio of calcium to nitrogen fertilizers in greenhouse can increase the ratio of sugar to acid and the content of Vc.Calcium application has no significant effect on the yield of fruit but appropriate proportion of nitrogen and calcium can increase the single fruit weight.
