将一年生核桃实生苗上作为砧木，开春后在距离地面5cm左右直接平茬，然后施肥浇水，松土除草让其快速生长，到5月中下旬，利用方块形芽接进行了新品种核桃嫁接，一种是在嫩枝上大约30～40cm的部位的上进行嫁接，另一种是在嫩枝上大约10～20cm的部位进行嫁接。两种试验方法中嫁接的时间和嫁接的方式方法及嫁接后的管理相同。试验结果表明：低部位的嫩枝上嫁接的苗子嫁接成活率高，生长速度快，当年出苗圃一、二级合格苗比例高。

This article studies the effects of different parts of rootstockson the growht andeconomic values of new species of walnut square-shapedbudding .The annual growth walnut seedlings are taken as rootstocks , and are directly stumped at the height of 5cmfrom the groundat the beginning ofthe spring .And then they growrapidlythroughfertilization wateringand weeding tillage .At the late ofMay ,new varieties of walnut are-grafted with square -shaped budding :the one way is tograftatthe30 - 40cm partofburgeons ;the other way is tograftatthe10 - 20cm part of burgeons .Both ways have the same grafting time ,methods and management after grafting .The experimental results show thatthe survival rateofgrafting seedling at the lower part of the grafted shootsis highand growsfast ;the proportion of qualified seedlingswhich belong to the first and second stage is high .
