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%。
The sweet cherry varieties - red light foliar sprays of plant growth regulators paclobutrazol, chlormequat, the application of the topping and erasing a pair of shoots, branches with branches, roots and other control measures to promote long flowers, the hormone protection Fruit, artificial pollination test. The results showed that: paclobutrazol 200 × 10-6 concentration can significantly inhibit the growth of shoots, the second year the formation of spur, differentiation of flower buds, and some fruit fruiting results, the first three years into the initial fruit, but 1000 × 10 -6 concentration over inhibition is too strong, the second year and even the third year are not pumping out the tip, the appropriate concentration of 200 × 10-6 ~ 500 × 10-6; CCC inhibitory effect is poor, the concentration reached 6000 × 10 -6 has a certain inhibitory effect; pull the branches to take control of the branches to control the tree, expand the crown, control the growth of shoots and promote collateral formation better. Topping and erasing auxiliary shoots, root cause control is poor. Treating young fruit stalks with gibberellin 50 × 10-6, 100 × 10-6 and 200 × 10-6, the effect of keeping fruit is obvious, the result rate is 31.40%, 36.30% and 48.10% Kinetin does not work well. With 13-38 varieties of pollen to the red light pollination, fruit set significantly increased, reaching 25.37%; with purple pollination also have good results, reaching 22.07%.
