He Weihua 1 ,Wang Qin 1 ,Zhang Shiying 1 ,Huang Xiangan 1 ,Li Shanhu 2 ,and Huang Chunxia 2 ( 1 Zhengzhou Fruit Research Institute,CAAS,Zhengzhou,Henan454009China;2 Dangshan Orchard,Dangshan,Anhui 235391China)  
The results of two year experiment demonstrated that the fresh and dry weight of leaf,the contents of chlorophyll and N,P,K in leaf were not affected by bagging of Suli pear variety;on the contrary,the contents of K,Ca ,Mg in mature fruit were decreased by10.6%,58%and9.3%;the total sugar and Vc contents in mature fruit were also reduced by0.9%and7.4mg /100g,respectively.The yield was decreased by around13.4%and the average fruit size became much smaller.Com-pared to the fruit-bagging treatment ,the parameters mentioned above increased obviously or even higher than that of CK un-der the treatment of bagging and after calcium spraying.Furthermore,those parameters were increased also at the treatment of three kinds of calcium spraying while no bagging was used;the yield was increased by2.9%~7.4%.Judging by the total effect of spraying,calcium humate and Gaonenggai were better than Bugaiwang.
