| 中文摘要: |
| 测定陕西省渭北不同地区优质示范园红富士果树叶片的养分含量,并运用DRIS、M-DRIS和DOP三种不同方法对果树的营养状况进行诊断。结果表明,陕西省各地区的叶片养分含量差异显著。延安市、铜川市和宝鸡市苹果叶片内最缺的养分是Cu,渭南市苹果叶片内最缺的是Ca,咸阳市苹果叶片内最缺的是Mn。五个地区相比,铜川地区苹果叶片内养分最不平衡。最后,给出了陕西省渭北各市示范园红富士果树各种养分需求顺序。 |
| 英文摘要: |
| The mineral element content of leaves sampled from Fuji apple excellent demonstration orchards in Weibei area of Shaanxi Province was analysed.The nutrient diagnosis of apple leaf was investigated by DRIS, M-DRIS and DOP.The results were as follows: (1) The available nutrient content of leaves was significantly different among different orchards. (2) There were nine mineral elements that were diagnosed in apple leaves of every orchard.The most deficiency element among those nine elements in orchards in the regions of Yan' an, Tongchuan and Baoji was copper (Cu) , while that in Weinan was calcium (Ca) , in Xianyang was manganese (Mn) . (3) The NII and ∑DOP of apple leaf in orchards of every region were accounted.The nutrient of apple in Tongchuan orchards was of the most imbalance among the orchards of the five regions. |
