- 摘要:
- 以黔南州8个县（市）核桃优树叶片与土壤为试材，对土壤性质和叶片营养元素的关系进行相关分析，以期研究土壤性质对叶片营养元素的影响。结果表明：土壤有效钾含量显著影响叶片钙的含量；土壤速效氮含量显著影响叶片钾的含量；土壤交换性钙含量显著影响叶片锰的含量；土壤交换性镁含量显著影响叶片镁的含量；土壤有效磷含量显著影响叶片氮的含量。试验表明核桃优树叶片营养元素的吸收与土壤养分密切相关，土壤养分状况显著影响核桃优树叶片营养元素的供给。
- Abstract:
- Taking sample of soil and leaves of superior Juglans sigillata in the field of eight counties of Qiannan state as materials,the relationship between soil property and nutrient element of leaves was analyzed.In order to study the influence of soil properties on leaf nutrition.The results showed that the available N of soil significantly affected the K content of leaves;the available K of soil significantly affected the Ca content of leaves;the exchangeable Ca of soil significantly affected the Mn content of leaves;the exchangeable Mg of soil significantly affected the Mg content of leaves;the available P of soil significantly affected the N content of leaves.The absorb of nutrient elements of superior Juglans sigillata leaves was closely related to soil property,soil property significantly affected the supply of nutrient elements of superior Juglans sigillata leaves.
