本试验用8个喷施处理，赤霉素（GA3）50mL和氧化二甲基哌啶嗡（MC）10mL分别在植株开花后5d，1％硝酸钾（KNO3），GA3＋KNO3，MC＋KNO3，FF，GA3＋FF，MC＋FF分别在播种后42，49，56，63d喷施，以测定赤霉素（GA3）、氯化二甲基哌啶嗡（MC）和高钾叶面肥（FF）对促进毛豆植株生长，提高产量和未成熟种子糖含量的效果。以清水喷施为对照。本试验在位于泰国的亚洲蔬菜研究发展中心试验田进行。研究结果表明，喷施MC的处理获得了最大的整株重和更多的分枝数，同时也获得最高的商品美产量和商品荚数；喷施MC＋KNO3混合液的处理获得了最大的植株节间数和分校数，而喷施MC＋FF混合液的处理增大了豆荚的体积。只喷施高钾叶面肥的处理则获得了最高的鲜豆粒重，最高的总可溶性固形物含量和蔗糖含量。由此说明，MC对促进毛豆植株的生长，提高产量有明显的作用，而FF则对提高毛豆的品质有效，GA3对毛豆的生长和品质无明显的作用效果。
In this experiment, 8 treatments were sprayed with 50 mL of GA3 and 10 mL of MBDM at 5 days after flowering, with 1% potassium nitrate (KNO3), GA3 + KNO3, MC + KNO3, FF, GA3 + FF , MC + FF were sprayed on the 42, 49, 56, 63 days after sowing to determine the effects of GA3, MC and FF on the growth of soybean plants , Increase the yield and immature seed sugar effect. Spray water as a control. The experiment was conducted in the experimental field of the Asian Vegetable Research and Development Center in Thailand. The results showed that the maximum whole plant weight and more branches were obtained by spraying MC, and the highest yield and the number of pods were also obtained. The treatment with MC + KNO3 sprayed the largest plant section The number of treatments and the number of colonies, while spraying MC + FF mixture increased pod volume. Treatment with only high-potassium foliar fertilizer yielded the highest fresh weight of grain, the highest total soluble solids, and sucrose content. Therefore, MC played a significant role in promoting the growth of soybean plants and increasing the yield, while FF was effective in improving the quality of soybean and GA3 had no significant effect on the growth and quality of soybean.
