摘　　要：研究结果表明，花生专用叶面肥能增加花生幼苗根长、根系体积、鲜重和干重，提高根系活力。其中以浓度为２０００ｍｇ／Ｌ的处理最明显。专用叶面肥还能提高幼苗根的可溶性糖和可溶性蛋白质含量，增加花生根瘤鲜重和干重，提高根瘤固氮酶活性。Special foliar fertilizer for peanut was developed by soil and fertilizer institute, Guangdong academy of agricultural sciences. The experimental results are as follows: Special foliar fertilizer result in increase of the length, volume, fresh weight of root of peanut seedling. By applying special foliar fertilizer, the root activity, soluble sugar and soluble protein content in peanut root were enhanced. After peanut plants at florescence were treated with special foliar fertilizer, fresh nodules and dry nodules weight were heavier than that of control and nitrogenase activity was raised.
