| 中文摘要: |
| 为进一步科学合理进行万州玫瑰香橙（‘塔罗科血橙新系’，C.sinensis‘Tarocco’）施肥，连续5年开展了玫瑰香橙果园土壤和叶片营养分析。结果表明，土壤中，pH和有机质低于适宜值，但都有上升趋势。N、K、Ca、Mg呈降低趋势，但均处于适宜值范围内。Cu、Mn、B表现相同趋势，但均大大高于适宜值上限。P、Zn处于低限水平，Te一直表现极度缺乏。叶片中，N、P、Ca、Mn、Fe整体表现上升趋势，且基本在适宜值范围内。Mg含量比较稳定且适宜。K、S、Cu、Zn、B始终表现缺乏，但K逐年在提高，Cu、Zn、B整体表现下降趋势。综上，结合玫瑰香橙品种特点，创新提出针对不同树龄，增施有机肥、增施一次冬肥、叶面补充中微量元素的施肥建议，广泛应用于生产。 |

| In order to carry out further scientific and reasonable fertilization of ‘rose orange’（C.sinensis‘Tarocco’），soil and leaves samples of rose orange were analyzed for five consecutive years. The results showed that both pH and organic matter in rose orange soil were lower than the appropriate value, but showed an upward trend. N ，K ，Ca and Mg decreased year by year, and were both normal. Cu, Mn and B presented decline trend, but all of them were much higher than the upper limit of the optimum value. P and Zn tended to be deficient and Te content had been extremely deficient in all test years. The leaf results showed that N ,P , Ca , Mn and Fe increased yearly and were within the appropriate range. Mg was relatively stable, and the difference between the detected values was small. K, S, Cu, Zn and B content was always in short supply, but K was increasing year by year, and Cu, Zn and B got a declining trend in detection years. According to the test results, combining with the characteristics of the rose orange varieties, The countermeasures of fertilization,which was according to different ages, increasing organic fertilizer, getting another fertilizer in December, and adding foliar fertilizer were put forward and widely applied in actual production. |
