本试验利用不同浓度的BcFA对甘薯秧苗进行浸秧,研究了其对甘薯形态、生理性状和产量的影响。结果表明,BcFA浸秧能促进根系发育、增加分枝数和分枝长度,提高叶片叶绿素含量(11.7％)、叶水势和叶片含水率及其秧苗成活率,改善薯块构成,尤其是提高大、中薯块比率。甘薯增产26.21％,且达到显著水平。并提出较高产量和较高经济效益的浸秧浓度。 In this experiment, sweet potato seedlings were flooded with different concentrations of BcFA, and the effects on the morphological, physiological characters and yield of sweet potato were studied. The results showed that BcFA flooding could promote root development, increase branch number and branch length, increase leaf chlorophyll content (11.7%), leaf water potential and leaf water content, and seedling survival rate, and improve potato composition, , The ratio of potato tuber. Sweet potato yield 26.21%, and reached a significant level. And put forward a higher yield and higher economic efficiency of the seedling concentration.
