| 摘要: |
| 以不同年龄苹果幼树为试材,研究了几种植物生长调节物质对幼树营养生长、越冬抽条、花芽形成和座果的影响。结果表明,对定植当年和第二年的幼树,点涂含有细胞分裂素和微量元素的制剂——点枝灵软膏,可以定位促进当年生芽萌发抽梢,增加1～2次新梢发生量,从而促进幼树营养生长,使其迅速达到早结丰产所需的枝量(比对照至少早1～2年);对1～2年生幼树于早春2～3月喷施2次100倍防抽灵,可以防止苹果幼树越冬抽条,而对照抽条率达40%。应用烯效唑和刻芽环剥技术可以使苹果幼树适期成花或提早成花,而且达到丰产所需的成花数量。应用多效唑或烯效唑和果丰素技术可以明显提高苹果座果率(比对照增加约1倍)。 |

| Abstract: |
| The effect of some plant growth regulating substances on vegetable growth,bud sprout- ing.shoot witheringin late winter,flower bud formation and fruit setting of the young apple trees of different cultivars were studied.Daub ofDianzhilingointment(a preparation consisting of CTK and mineral elements)to buds of shoot in the same and the second year of planting can significantly enhance bud sprouting to form shoots and thus increased vegetative growth(to two to many times than the control).However,the length o... |
