摘要
以北疆主栽品种"垦鲜枣1号"为试材,通过对5个不同质量浓度烯效唑+青鲜素组合处理进行试验,研究其对"垦鲜枣1号"枣头、二次枝、枣吊及叶片生长发育影响。结果表明,不同处理和对照间枣头长度、粗度差异极显著(P<0.01),枣头节间长度及二次枝长度、粗度、二次枝节间长度、枣吊长度存在显著差异(P<0.05),而叶面积之间差异不显著。烯效唑+青鲜素处理使枣树树形矮化紧凑,新梢萌发数量减少,摘心生产率是以前的2.2倍,吊果率提高128%。
The main jujube cultivar ＂Kenxianzao 1＂ of north Xinjiang was used as the material and an experiment was conducted with five different mass concentrations of S-3307 combined with maleic hy- drazide to study the growth and development of extension shoot, secondary shoot, bearing shoot and leaf. The results showed that length and tickness of extension shoot showed significant （P〈0.01） difference among the treatments;length of internode, length of secondary shoot , tickness of secondary shoot, length of secondary shootnode, length of bearing shoot and leaf area were not significantly different（P〉0.05）. It made the jujube trees dwarf and decreased the new shooting rate. Productivity of pinching is 2. 2 times high than before, and percentage of total fruits to total bearing shoot in creased by 128%. The results provide the theoretical basis for application of the plant growth retard ants on the jujube trees in north Xinjiang.
