摘要
以5 a生、15a生和25 a生的库尔勒香梨为研究对象,分别喷施10,15,20,25 mmol/L的CaC12和Ca(NO3)2,研究不同Ca2+溶液和不同浓度处理对不同树龄库尔勒香梨树叶片Ca2+吸收的影响.研究结果表明,不同Ca2+处理后叶片中的Ca2+含量呈不同程度的增加.在5月中旬至6月中旬,5 a生香梨树喷施20 mmol/LCaCl2,15 a生香梨树喷施10 mmol/L Ca(NO3)2,25a生香梨树喷施20 mmol/L CaCl2更有利于叶片对Ca2+的吸收.初步推断,在5月中旬至6月中旬,5 a生香梨树喷施20 mmol/L CaCl2,15 a生香梨树喷施10 mmol/LCa(NO3)2,25 a生香梨树喷施20 mmol/L CaCl2更有利于叶片对Ca2+的吸收.
Abstract
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/LCa (NO3)2,25 years were sprayed with 20 mmol/L CaC12 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.
