- 摘要:
- 以2年生盆栽“华红”苹果树为试材，研究了嫁接SH38中间砧对“华红”苹果不同部位矿质元素含量的影响。结果表明：不同砧木对“华红”苹果不同部位矿质元素含量均有一定的影响，“华红”苹果树嫁接SH38中间砧后，降低了叶片、新梢、主干、主根对多数矿质元素的吸收和利用能力，提高了侧根对多数矿质元素的吸收和利用能力；同一矿质元素在各个器官的含量明显不同，各矿质元素中，除铁（Fe）元素主根含量高于其它3个部位外，其余各矿质元素叶片含量均高于其它3个部位；同一矿质元素在不同径级根系的含量明显不同，多数矿质元素均在d≤0.5 mm根径级的毛细根系内含量最高。“华红”苹果树嫁接SH38中间砧后，降低了除侧根外各器官对多数矿质元素的吸收和利用能力，在土壤贫瘠地区应加强对肥料的施用。
- Abstract:
- Taking biennial potted ‘Huahong’ apple as test material，the effect of grafting SH38 intermediate stock on the content of mineral elements in different parts of ‘Huahong’ apple tree was studied.The results showed that all the different stocks had some effect on the contents of mineral elements in different parts of ‘Huahong’ apple tree.The grafting of SH38 intermediate stock on ‘Huahong’ apple tree increased those of lateral roots’ absorption and utilization of most nutritive elements but decreased blades，shoots，trunk and trap roots’ absorption and utilization of them.The content of the same mineral element was distinctly different in different organs，the content of Fe in trap roots was obviously higher than that of other three parts and the content of other mineral elements in blades were all significantly higher than that of other three parts.The content of same mineral element was apparently different in different classes of rhizomes and most of the mineral contents showed the highest amount in d≤0.5 mm class of fine roots.The grafting of SH38 intermediate stock on ‘Huahong’ apple tree increased lateral roots’ absorption and utilization of most nutritive elements but decreased blades，shoots，trunk and trap roots’ absorption and utilization of them，should strengthen the application of the fertilizer in poor soil region.
