| Abstract: |
| Mineral element content of walnut leaves were comparatively analysised under the condition of drip irrigation and border irrigation. The result showed that except content of Phosphorous, Calcium and Ferrum in premature senescence walnut leaves under the drip irrigation condition were 111.1%, 9.6% and 11.1% higher than that in normal walnut leaves under the flood irrigation condition, Content of others mineral elements were lower in varying degrees than that in normal walnut leaves under the flood irrigation condition, which were particularly so with content of secondary and microelements. Premature senescence of walnut leaves was caused by short of Potassium, Magnesium, Manganese, and Zincum mainly. Drip irrigation and fertilization method has an effect to walnut trees's absorption of secondary and microelements. Application amount of secondary and microelements of walnut tree should be increased while irrigation method changed from flood irrigation to drip irrigation. |
