由于果树是多年生植物,再加上现在果园普遍存在着忽视有机肥的施用,单一施用化肥,往往使果园士壤中某些养分元素出现缺乏或不足。而引起果树缺素症的出现。如何区分和辨认果树缺素症,并且有针对性的治疗,是广大果农急需解决的问题。叶片是树体同化代谢功能最活跃的部位,是制造各种生命物质的主要加工厂。养分供应的变化在叶片上的反映最明显。所以各种类型的缺素症一般均表现在叶片上,其表现特征归纳为以下几类:
Because fruit trees are perennials, coupled with the widespread omission of organic fertilizer in orchards nowadays, single application of fertilizers tends to make some nutrient elements in the orchards lacking or insufficient. Which caused the emergence of fruit tree deficiency syndrome. How to distinguish and identify fruit tree deficiency, and targeted treatment, is the majority of farmers in urgent need of solution. The leaves are the most active parts of the tree for assimilation and metabolism and are the major processing plants for the manufacture of various life substances. Changes in nutrient supply on the leaves reflect the most obvious. Therefore, various types of deficiency are generally manifested in the leaves, the performance characteristics summarized as the following categories:
