把全光迷雾条件改装成半全光迷雾条件 ,选用当年生嫩枝做插条并用生长素和根宝 - 3进行处理 ,提高了插条的生根率。其中以IBA效果最好 ,IAA、NAA和根宝依次次之。 50 0× 10 - 6的IBA处理下的插条生根率、平均根量、平均根长与根数最大值分别高于对照 79.5%、2 0 %、2 4 0 %、550 %。根宝 - 3对日本晚樱嫩枝生根的促进效果不明显。在半全光迷雾条件下 ,使中午温度控制在 2 5～ 30℃ ,夜间温度控制在 16～2 1℃ ,最有利于生根 Change the conditions of all-optical fog into semi-all-optical fog condition, choose the annual shoots as cuttings and use auxin and root-3 to improve the rooting rate of the cuttings. IBA was the best, followed by IAA, NAA and Genbao. The rooting rate, average root length, average root length and root number of the cuttings under 50 0 × 10 - 6 IBA treatments were 79.5%, 20%, 240% and 550% of the control, respectively. Root Po - 3 on the Japanese cherry tender shoots to promote the effect is not obvious. Under the condition of semi-all-optical fogging, the temperature at midday is controlled at 25-30 ℃ and the nighttime temperature is controlled at 16-21 ℃, which is most beneficial to rooting
