以 5～ 6年生高接木奈李为试材 ,进行喷施多效唑试验。结果表明 ,于新梢旺长期喷施 5 0 0mg/kg的多效唑 ,对木奈李新梢有明显的抑制作用 ,且随喷施次数增多抑制作用增强 ,喷 3次新梢生长量相当于对照的 69%。在抑制新梢生长的同时 ,增加了短枝比例。喷多效唑有疏果现象 ,但疏除程度符合生产要求 ,且对果实的最终大小及单果重无不良影响。由于喷施多效唑的持效期较短 ,生产中应根据树势强弱 ,喷施 2次
To 5 to 6 years old high mung bean as test material, spray test paclobutrazol. The results showed that the application of 500 mg / kg paclobutrazol at the long shoots significantly inhibited the shoots of mimi and increased with the increase of spraying times. The growth of shoots sprayed 3 times was equivalent to that of the control Of 69%. In inhibiting the growth of shoots at the same time, increased the proportion of short branches. PP338 has the phenomenon of fruit thinning, but the degree of thinning in line with production requirements, and the final size of the fruit and fruit weight without adverse effects. As the effect of spraying paclobutrazol shorter, the production should be based on the strength of the tree, spray 2 times
