摘　　要：以"丹波黑"大豆为材料,研究叶面喷施5%(v/v)甲醇对中性土壤、红壤和黄壤条件下大豆的生长和生理特性的影响。结果表明:叶面喷施甲醇后,中性土壤、红壤、黄壤中大豆的株高均显著增加,叶片相对叶绿素含量无显著变化;中性土壤和红壤中大豆叶片鲜重和干重无显著变化,黄壤中大豆叶片重量显著增加。随着甲醇处理时间的延长,中性土壤中大豆叶片可溶性糖含量呈先上升后下降的趋势,可溶性蛋白含量呈先下降后上升趋势;红壤中可溶性糖含量缓慢增加,可溶性蛋白含量呈先上升后下降趋势;黄壤中叶片可溶性蛋白和可溶性糖含量均呈现显著递增的趋势。以上结果表明,叶面喷施5%甲醇可以显著促进黄壤中大豆的生长。Effects of foliar application of 5%（v/v）methanol on growth and physiological characteristics of Tamba black soybean grown in neutral,red and yellow soil were investigated in this study.The results showed that foliar methanol application significantly increased the plant height and had no significant effect on relative leaf chlorophyll content of soybean grown in neutral,red and yellow soil.The effects of methanol treatment on leaf fresh weight and dry weight were not obvious when soybean was grown on neutral soil and red soil.However,methanol treatment increased weight of soybean in yellow soil significantly.With the extension of methanol treatment time,soluble sugar content of soybean grown in neutral soil,firstly increased and then decreased,but soluble protein content firstly decreased and then increased;in red soil soluble sugar content slowly increased,soluble protein content firstly increased and then decreased;both of them significantly increased in yellow soil.In conclusion,foliar application of 5% methanol could significantly promote soybean growth in yellow soil.
