Abstract

In order to improve the grafting survival rate and qualified seedling percentage of Juglans regia,the grafting survival rate,new shoot increments and cost were compared when four kinds of grafting methods were adopted.The results showed that:(1)The optimum grafting seedling period of Juglans regia in the hilly areas of central Sichuan was between before germination on early March and sprouted leaves,the grafting time was properly in advance or delayed according to the phenophase.(2) The methods of seedling grafting and phloem bark grafting were suitable to carry out in the experimental field in spring,grafting was sooner rather than later in the same period,seedling growth had a significant difference in different scions-tock combination.(3) Phloem bark grafting was the most suitable grafting method in climate zone similar to the experimental field and had better wound healing,high survival rate,growth and qualified seedling percentage.Seedling grafting took the second place,this method worked fast and had short cycle and low cost,but lower increment and qualified seedling percentage.Patch budding and summer budding were not suitable for popularization and application in the area.
