叶片分析是柑桔营养诊断的一种重要手段。由于土壤营养诊断会受到土壤中养分分布高度不均匀性的影响,分析资料的应用受到相当程度的限制,而叶片分析结果,能比较有效地反映出柑桔树体的营养状况,因此,它已成为柑桔施肥的重要的科学依据。前卫桔园作为我国北缘地区柑桔的重要产地,它连续多年大面积丰收的实践已引起了国内外众多柑桔种植专家的注意。合理施肥是该桔园温州蜜柑大面积连续高产的重要经验之一。为了研究本场高产桔园柑桔树体的营养特点,以及总结他们科学的施肥技术,以便在上海乃至整个北缘地区桔园推广他们成功的经验,我们开展了本项研究。
Leaf analysis is an important tool for the diagnosis of citrus nutrition. Because soil nutrition diagnosis is affected by the highly inhomogeneous distribution of nutrients in the soil, the application of analytical data is limited to some extent. However, leaf analysis results can more effectively reflect the nutritional status of citrus trees. Therefore, Citrus fertilization is an important scientific basis. As an important origin of citrus in the northern margin of China, the avant-garde orange garden has attracted the attention of many citrus growers both at home and abroad for many years. Reasonable fertilization is one of the important experiences of continuous production of large area of Satsuma mandarin orange in this orange garden. We conducted this study in order to study the nutritional characteristics of this high-yield orange citrus tree and to summarize their scientific fertilization techniques in order to promote their successful experiences at Orange Park in Shanghai and throughout the North Rim.
