近年来,我们对苹果腐烂病进行了“枝干涂药”和“重刮皮”两项措施防治效果比较试验。重刮皮防治苹果腐烂病有削弱树势的副作用,表现在:具有局部(处理部位)控制,局部(非处理部位)促进的双重性。这种促进局部发病的副作用,在管理水平较高,长势健壮的果树上表现不明显;对管理水平较低,而病情较重,长势较弱,结果较多的果树上表现较突出。因此,重刮皮措施在应用上有一定局限性,要因树制宜,慎重施用。而涂药措施防治腐烂病的不利因素较少,宜于普及推广。
In recent years, we conducted a comparative experiment on the control effect of two measures of “sticky coating” and “scraping skin” on apple rot. Heavy skin scraping prevention apple rot disease has the effect of weakening the shores, manifested in: with local (treatment site) control, local (non-treatment site) to promote the duality. This side effect of promoting local disease is not obvious on fruit trees with high management and vigorous growth. Fruit trees with lower management level, heavier illness, weaker growth and more fruit are more prominent. Therefore, the heavy scrape skin measures have some limitations in the application, due to the tree system should be carefully applied. However, there are fewer unfavorable factors for applying the drug to prevent the rot disease, which is suitable for popularization and promotion.
