近年 ,生产上通过高接更新品种的应用已较普遍 ,其中 ,脐橙的高接换种占到相当的比例。但高接树常因挂果过多 ,使树体日趋衰弱 ,严重的还会造成死亡。本试验旨在寻找合适的挂果量 ,促进高接脐橙的可持续优质丰产。1　材料与方法试验设在丽水市城关镇塔下高接脐橙园内 ,高接脐橙 In recent years, the production of new varieties through the use of high-access has been more common, of which, high exchange of navel orange accounted for a considerable proportion. However, the high tree is often too much due to fruiting, the tree becomes increasingly weak, serious will result in death. The purpose of this experiment is to find a suitable amount of fruiting and to promote the sustainable yield of high quality navel orange. 1 Materials and Methods The experiment is located in the city of Lishui Chengguan Town, under the high-Navel Orange Garden, high-Navel Orange
