苗木枝接保湿方法研究

Study on Method of Moisture Kept for Branch-grafting of Seedling

摘要:

枝接是苗木嫁接的主要方法之一，一般在春季进行。枝接时，为了节省接穗，一般将1根枝条剪截成若干个接穗，嫁接后，由于接穗顶部切口暴露在空气中，易失水枯萎，降低生活力，影响嫁接成活。2000年春季开始，在果树苗、绿化树苗上开展枝接保湿方法研究。结果表明：用塑料薄膜封盖接穗顶部切口减少接穗水分蒸发8％～10％，平均嫁接成活率达96．4％。

Abstract:

Branch-grafting is one of main method of seedling grafting that operates usually in spring. During branch grafting, cut a number of scions on a branch cutting generally in order to save scions; after grafting, it is easy to lose water and wither due to the top scion cut exposing in the open air, decrease vital force which influences survival of the grafting.A study on keeping moistureof the scion has been carried out in the seedling of fruit and greenery tree started from the spring of 2000. The result showed that thetop scion-cut covered withplastic decreased the water evaporation by 8%~10% and the average survival rate of the grafting reached 96.4%.
