以4～5年生甜樱桃幼旺树为试材。在果实采收后(新梢旺长前的20cm左右)的6月14日,按树冠投影面积用0.5、1、1.5、2g/m~2的多效唑,进行土壤根施试验处理。通过3年试验表明:各处理均明显抑制新梢顶端生长、节间缩短、叶片增厚,短枝量,特别叶丛枝明显增多,增加营养物质积累,新梢停长早、防止了抽条和死株。花芽形成效果比对照增加6～8倍,单果重平均增加37～75％。按1g/m~2的施用量,株产增加1～1.5倍;平均亩产增加2.64～5.17倍。试验表明:以土施1g/m~2处理的效果最佳。
4 to 5-year-old sweet cherry tree as a test material. After harvesting the fruit (about 20 cm long before the new shoots grow), on June 14, the paddy soil was treated with 0.5, 1, 1.5, and 2 g / m ~ 2 paclobutrazol at the projected area of the crown. After 3 years of experiment, the results showed that: All the treatments significantly inhibited the tip growth of new shoots, shorten the internode, thicken the leaves, short shoots, especially the thick branches and shoots, increased the accumulation of nutrients, And dead strain. The flower bud formation effect increased by 6 ~ 8 times than the control, single fruit weight increased by an average of 37 ~ 75%. According to the application rate of 1g / m ~ 2, the yield increased by 1 ~ 1.5 times; the average yield per mu increased by 2.64 ~ 5.17 times. Experiments show that: soil 1g / m ~ 2 treatment best.
