对5年生明星杏土施不同剂量的多效唑试验表明,明星杏对多效唑较敏感,施用含量为15%的多效唑以8g为宜。明星杏土施多效唑8g平均单株产量较对照提高28.9%,而土施多效唑10和2g分别只有对照的68.3%和32%。明星杏土施多效唑8、10和12g,短果枝平均节间长度分别比对照缩短了0.24、0.23和0.20cm,中果枝的平均节间长度分别比对照缩短了0.12、0.18和0.08cm。
Experiments on 5-year-old star apricot soil with different doses of paclobutrazol showed that apricot was more sensitive to paclobutrazol, and 8g paclobutrazol was suitable when applied to 15% paclobutrazol. The average per plant yield of the star apricot soil paclobutrazol 8g was 28.9% higher than that of the control, while soil paclobutrazol 10 and 2g were only 68.3% and 32% of the control respectively. The average internode length of short apricot trees was reduced by 0.24, 0.23 and 0.20 cm, respectively. The average internode length of middle apricot trees was reduced by 0.12, 0.18 and 0.08 cm respectively compared with the control.
