3种核桃嫁接方法对比试验

为了提高核桃嫁接成活率,在不同试验点最适宜的肥水条件下,对核桃子苗嫁接、芽接、绿枝接的成活率、新梢生长量及成本进行对比研究。结果表明,在熟练掌握嫁接技术的情况下,嫁接方法不是影响嫁接成活的主要因素,影响嫁接成活的主要因子是嫁接时期。同一时期嫁接时间宜早、不宜晚。子苗嫁接、绿枝接、芽接相比较,子苗嫁接育苗周期短、成本低、技术易掌握,适宜工厂化育苗。

Comparison of Three Walnut Grafting Methods

In order to improve survival rate of walnut grafted,comparison of new shoot increments and cost were made between seedling grafting,bud grafting and green branch grafting of walnut.The results showed that the main factors influencing survival rate was not grafting methods but grafting time.During the same period,the earlier grafting time was,the better effect would be.Seedling grafting need shorter seedling period and lower cost,and was easier to learn,than the other methods.So it could be used in industry seedling.
