Effects of Different Calcium Treatment on Korla Fragrant Pears (Pyrus bretschneideri) Leaves Calcium Absorption

The aims of this article was to research the effects of different calcium treatments on Korla Fragrant Pears leaves of different age:5 years old,15 years old and 25 years old Korla Fragrant Pears were used as test materials,which were sprayed with CaCl2 and Ca(NO3)2 of 10,15,20,25 mmol/L.Research results show that calcium ion content in Korla Fragrant Pear leaves increased in varying degrees after different treatment with calcium ion.In the middle ten-day of May and June,Korla Fragrant Pears of 5 years were sprayed with 20 mmol/L CaCl2,Korla Fragrant Pears 15 years were sprayed with 10 mmol/L Ca(NO3)2,25 years were sprayed with 20 mmol/L CaCl2 which was more beneficial to calciumion absorption of pears leaves.In the middle ten-day of May to the middle ten-day of June,spraying the pears of 5 years with 20 mmol/L CaCl2,spraying the pears of 15 years with 10 mmol/L Ca(NO3)2,spraying those of 25 years with 20 mmol/L CaCl2 was more beneficial to calcium absorption of leaves.
