在一定范围内,叶片营养诊断可作为对果树潜在营养状况进行诊断的参考标准。当前猕猴桃缺素症叶片诊断可分为叶片外部形态诊断、叶片营养分析诊断及对照已有的诊断标准加以诊断3种。该文对各类诊断方法进行了概述,对3种诊断方法的优势和不足进行了比较分析,对实施3种诊断方法时的注意事项进行了归纳。提出猕猴桃缺素症叶片诊断的发展趋势,指出在今后的研究中,应根据具体情况,选择适宜的诊断方法,同时应综合运用各种诊断方法,充分发挥多种方法的优势。应积极探索猕猴桃树体对养分缺乏的生理生态适应性以及养分之间的相互作用,探寻更好的营养诊断方法和途径。
Within a certain range, leaf nutrition diagnosis can be used as a reference standard for the diagnosis of potential nutritional status of fruit trees. Current kiwifruit deficiency disease leaf diagnosis can be divided into external morphology diagnosis leaves, leaf nutrition analysis and diagnostic criteria have been diagnosed to be diagnosed 3 kinds. This article gives an overview of various diagnostic methods, compares and analyzes the advantages and disadvantages of the three diagnostic methods, and summarizes the precautions when implementing the three diagnostic methods. The trend of the diagnosis of kiwifruit-deficiency leaves was pointed out. In the future research, we should select the appropriate diagnosis method according to the specific conditions, and at the same time we should make full use of the advantages of many methods by comprehensively using various diagnosis methods. We should actively explore the physiological and ecological adaptability of kiwifruit trees to the lack of nutrients and the interaction between nutrients to explore better nutrition diagnosis methods and ways.
