【摘要】 选用8920mf多叶苜蓿(Medicago sativa cv. 8920mf)作为扦插材料,以常用生根剂吲哚丁酸-萘乙酸(0.2%)对其进行处理,研究自然条件下苜蓿的扦插技术及吲哚丁酸-萘乙酸的施用对扦插材料成活率、发芽天数、生根数、新株高、分枝数的影响,为大田应用扦插技术提供参考。结果表明,自然条件下苜蓿扦插要防止连续降雨对成活率的影响,施用吲哚丁酸-萘乙酸对扦插材料有明显的缩短发芽时间、促进生根、提高分枝数的作用。更多还原

【Abstract】 In this article,rooting agent(0.2%) that could promote the rooting ability of plant was used to deal with the cutting materials of 8920mf alfalfa in order to study the effects to the characters of the survival rate,the days of germinating,rooting ability,plant height and branches of the plant and give some advises about the cuttage of alfalfa under nature conditions.The result showed that the influence of the continous vainfall must be avoided at the begiaing of cuttage.The agent could not only promote rooting and increase the number of branches of the cutting materials remarkably but also reduce the time of germinating.更多还原
