地膜包扎技术在苹果树高接中的应用

Study on the Application of the Plastic Film Wraping Technique on the High Graft of the Apple Tree Species

苹果树在皮下接高接换种时，用0．007mm厚的聚乙烯微膜包扎接口与接穗，成活率高，省工，成本低，接穗萌发后可自行顶破地膜，可替代高接方法中套塑料袋等传统接穗保湿方法。

Apple tree was changed with new species by bark grafting method,i. e. wraping the contact and scion with 0. 007mm plastic film. Three advantages are as follows:high survival rate,lower cost and less labour. The scion could sprout through the plastic film. This method was one way to maintain moisture and to substitute the traditional plastic bag in the high graft of the apple tree.
