本文研究了在罗马尼亚南部皮特斯-马拉西内尼丘陵地区的特定条件下，不同灌溉方式对嫁接在MM 106砧木上的金冠苹果品种根系分布的影响。结果表明，不同灌溉处理对根系活动截面积（TRCSA）的影响大于对根系总截面积的影响。总TRCSA之和与果实产量、总TRCSA与树干横截面积年生长量呈显著正相关。这项研究还表明，从TRCSA的角度来看，在苹果树种植微喷灌和滴灌将是最好的方法，在这里讨论的自然和技术条件下使用。在温带气候区类似土壤和技术条件下，充分推荐为苹果推广的最佳灌溉方式。
Thepresent paper shows the effects of various irrigation methods on the distribution of roots in the Golden Delicious apple cultivar grafted on MM 106 rootstock under the specific conditions of the hilly region of Pitesti-Maracineni, Southern Romania. The results obtained here showed that a higher influence was induced by the different irrigation treatments to the active tree root cross-sectional area (TRCSA) versus the total TRCSA. A direct, linear and distinctly significant correlation was found between the sum of the total TRCSA and the fruit yield on the one hand, and between the total TRCSA and the annual growth in tree trunk cross-sectional area on the other hand. This study also revealed, from the TRCSA point of view, that in apple tree farming microsprinkler irrigation and drip irrigation would be the best methods to be used under the natural and technological conditions discussed here. They are fully recommended as the best irrigation methods in apple growing extension under similar soil and technology conditions in the temperate climate zone.
