【摘要】 对甜樱桃品种－红灯采用了叶面喷施植物生长调节剂多效唑、矮壮素，应用了摘心并抹除副梢、拉枝结合拿枝、断根等控长促花措施，进行了激素保果，人工授粉试验。结果表明：多效唑200×10－6以上的浓度能明显抑制新梢生长，第2年形成短枝，分化花芽，且有部分长果枝试花结果，第3年进入初果期，但1000×10－6以上浓度抑制作用过强，第2年乃至第3年都抽不出梢来，适宜浓度为200×10－6～500×10－6；矮壮素抑制效果差，浓度达到6000×10－6有一定抑制效应；拉枝结合拿枝对控制树高、扩展树冠，控制新梢生长，促进侧枝形成效果较好。摘心并抹除副梢，断根等控制效果较差。用赤霉素50×10－6、100×10－6、200×10－6涂幼果果柄，保果效应明显，成果率分别达到31．40％，36．30％和48．10％；细胞激动素效果不佳。用13－38品种的花粉给红灯授粉，座果率显著提高，达到25．37％；用大紫授粉也有良好的效果，达到22．07％。更多还原

【Abstract】 Paclobutrazol (pp333) and Chlorocholin chloride(CCC) were applied on the ’Hong Deng’ trees by foliar spray and top & sublataral shoots removal,shoot pulling & sprainning and root prunning methods were in applied in order to control the vegetative growth and promote the blossom; artificial pollination and fruit retention by GA and CTK application were also conducted. The result showed that 200 × 10-6 ~ 500 ×10-6 of pp333 was suitable for the purpose, the inhibition was too strong when the applied concentration was above 1000 ×10-6,and no new shoots appearred in the following and third years,the CCC had a weak inhibition effect except at 6000 ×10-6. The branch-pulling together with shoot-sprainning had good effects both on controlling tree height,shoot growth and on widening of canopy, promoting of lateral shoots. while top removal together with the sublateral removal had a weaker effect. When GA of 50 × 10-6, 100 × 10-6, 200 ×10-6 were brushed on the fruit stalks, the fruit retention effect was very good with the fruit setting rate of 31.40％， 36. 30％ and 48. 10％, respectively, while the effect of CTK (cytokinin ) was weaker. The fruit setting rate was increased to 25. 37％ and 22.07％ when pollinated with ’13 - 38’ and Black Tortarian,respectively.更多还原
