Abstract: In the crops product, calcium content is the important origin of human calcium nutritive elements. Calcium fertilization can enhance the calcium quantity in vegetative food, thus it would do favor to the health of the human being. If the new root growth is blocked or the transpiration reduces, and the calcium content in the crops suddenly reduces, it will affect the regular growing development of the crops. Through spurting Calcium fertilizer on the out root of the crops, it can have a fast effective supplement of the calcium need to the plant. This experiment tests the following conclusion through three foliage sprays continuously with different calcium content during blossom period, fruiting period and inflated period: comparing the apple output per hectare with spurting clear water, if spurting Calcium fertilizer with 160g/L, it can increase production 5666.6kg/hec, the rate is 14.4% and the analysis of variance is shown extremely significant level. If with 120g/L, it can increase 4888.8kg/hec, the rate is 12.4%, and the analysis of variance is shown significant level.
