| 摘 要： | 研究表明:高接芽数、冠径、单株叶面积、末级梢量和中间砧干周对高接换种树的早期产量有极显著影响。高接芽数多,末级梢增加,树冠恢复快,利于早果丰产,但易造成树冠郁闭;切接口直径与新梢长度、粗度成极显著正相关;随着嫁接部位升高,新梢数量增加而单枝生长量减小。提出高换树适宜的接芽为0.8～1.3个/1cm干周,投产树体指标为:冠径2m左右、单株叶面积10.0m~2、每平方米树冠投影面积的末级梢量50～100条。

| Abstract: | This experiment showed that the bud number of the top grafting, the diameter of the canopy, the leaf area of a single tree, the number of tip shoots and the diameter of the middle-piece-stock significantly influenced the early yield of the top-grafting-exchanging trees. The more bud number of top-grafting, the more number of tip shoots and the faster renewal of the canopy. The number also benefited the early fruiting and high yield. But it made the dense canopy. The cut diameter of grafting branches had a positive correlation with the length and diameter of shoots. If the site of the grafting was rised the numbers of shoots would increase and the growth amount of the single shoot decrease. There fore the appropriate budding numbers were 0.8-1.3 for each centimeter of the bole diameter. The indeses of the fruiting trees were: 2 meters of the canopy diameter, 10 square meters of leaf area for single tree and 500—100 tip shoots of each square meter canopy. |
