摘要
用 CA2 0 0 0钙宝叶肥在富士苹果 ( Malus pumila)树上进行大田对比试验 ,通过 2 a田间调查和室内分析表明 :CA2 0 0 0钙宝处理比对照的叶片净光合速率、气孔导度、胞间 CO2 浓度等光合功能显著增强 ,并能有效促进果树各个部分对钙、镁的吸收利用 ,使富士苹果树叶片、果皮、果肉的含钙量分别增加 35 %、83%和 1 0 0 % ,有效补充了果树所需的钙、镁含量 ,防止果实缺钙所造成的生理病害。
The field control experiment of CA2000 Cabo foliar fertilizer were conducted in Fuji apple trees. Through two years' field survey and laboratory analysis, the results showed that leaf photosynthesis, Pn, Gs, Ci, treated by CA2000 Cabo developed more prominent than untreated ones. It promoted absorbance and utilization of calcium and magnesium on each part of trees, increased the calcium contents of leaf, peel and pulf 35%, 83% and 100%, respectively compared with control, as well as replenished Ca, Mg trees needed, prevented physiology disorder.
