葡萄育苗一般采用先催根后扦插的方法,效果好,但费工费时。1999～2000年我们用黑色地膜覆盖育苗,取得了十分理想的效果。黑膜阻遮了阳光,抑制了插条顶芽萌发,使其贮存营养用于生根,加之其保墒增温效应,为插条愈伤组织的形成和生根创造了良好的条件,其生根率与常用激素处理后热催根扦插相当,且不用任何生根剂,省工省时效果好。 Seedling grapes generally use the first after the method of root cutting, the effect is good, but time-consuming work. From 1999 to 2000, we covered the nursery with black film and achieved a very good result. Black film obstruct the sunshine, inhibit the shoot bud germination, so that its storage of nutrients for rooting, combined with its warming effect of moisture, for the formation of cuttings and rooting created a good condition, and its rooting rate and Commonly used hormones heat treatment after root cutting quite, and without any rooting agent, saving time and labor is good.
