| 中文摘要: |
| 为了研究新型叶面铁肥对植物缺铁黄化的矫正效果，以10年生歪嘴李为试验材料，测定施铁处理对李叶片的叶绿素、营养状况、光合速率以及光能利用效率的影响。结果表明：新型叶面铁肥处理后，叶片叶绿素、铁含量显著提高，随着喷施次数增加，叶绿素呈递增趋势；喷施新型叶面铁肥后显著提高了叶片PSⅡ原初捕获激发能的效率（Fm/Fo）和光能转化效率（Fv/Fm），光合速率得到显著提升。综合比较，新型叶面铁肥比EDDHA-Fe的复绿效果好，且新型叶面铁肥400倍处理在第1年获得最佳效果。 |
| 英文摘要: |
| In order to study the efffictiveness of the new foliar iron fertilizer on the correction of iron chlorosis,the content of chlorophyll,nutritional status,photosynthetic rate and the light energy utilization efficiency were measured in leaves of the ten-year-old “Waizui”plum. The results showed that under the treatment of the new foliar iron fertilizer, the content of chlorophyll andiron increased significantly and the growth of the content of chlorophyll gradually with the increase of spraying times;at the same time original capture excitation energy efficiency (Fm/Fo) and efficiency of light energy conversion （Fv/Fm）in PSⅡgotimproved significantly and the photosynthetic rate increased significantly.Compared with EDDHA-Fe ,the new foliar iron fertilizer had a good correction to the iron chlorosis and the new 400 times foliar fertilizer iron treament got the best effectin the first year. |
