为了提高榕江县低产脐橙果园的产量,整形修剪方法,研究其对高接换种纽荷尔脐橙生长和产量的影响。结果表明：整形修剪可以显著增加纽荷尔脐橙冠幅和果实产量,尤以第3年最为明显,其冠幅是对照的1.95倍,单株挂果数较对照提高55%（增加46个）,单位面积产量比对照提高60%。整形修剪是一项改造低产果园的重要措施。

To improve the yield of Newhall Navel Orange low-yield orchard, training and pruning measure was used in this experiment. The studying results showed that the Newhall Navel Orange orchard yield was improved apparently because of applying training and pruning measure every year, especially the effect was most significant in the third year. Training and pruning, which is an important reforming measure to low- yield orchard, is worth to extension vigorously.
