摘　　要：酥梨果实套袋后,对叶鲜、干重,叶绿素和N、P、K含量,未发现有明显不良影响。而成熟果实中K、Ca、Mg含量值则分别下降10.6%、58%、9.3%,总糖下降0.9%,维生素C下降7.4mg/100g。平均单果变小,减产约13.4%。若采取喷钙后套袋,同单纯套袋相比,上述各项指标含量,均有明显提高,甚至接近或略超过CK处理的含量。对不套袋的梨果喷施(3种)钙肥,与CK相比,上述各项指标含量均有明显提高,增产2.9%～7.4%。3种钙肥喷施的综合效果,腐殖酸钙和高能钙稍好于补钙王。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.
