果树高接是抗寒栽培的一项重要措施。然而,由于高接的砧穗组合、高接方式、砧木的年龄等不同,高接后表现各有差异:有的表现良好,有的出现早衰、黄化,严重的甚至死亡。果树的黄化(即失绿症)是世界上相当广泛地存在的营养失调生理病害。诱致失绿的因子很多。本文针对高接后表现出的失绿,运用根系观察法、喷施微量元素法、叶分析法加以分析研究。
High fruit tree is a cold hard cultivation of an important measure. However, due to the different combinations of high-yielding scion combinations, high-yielding methods, rootstock age, and so on, the performance of high-yielding stocks varies. Some are well-behaved, some are premature, yellowish, severe and even dead. Yellowing of fruit trees (ie, chlorosis) is a rather widespread malnutrition physiological disorder in the world. Many factors cause the loss of green. In this paper, for the loss of green after the show, the use of root observation method, spraying trace element method, leaf analysis method to be analyzed.
