用2年生核桃实生苗为砧木,辽核3号为接穗,在清水县4月上中旬进行了舌接、插皮舌接、贴接、劈接、切接等五种枝接试验,结果表明:贴接的成活率最高,可达78%,是清水县核桃育苗的首选嫁接方法。插皮舌接的成活率为62%,苗木质量最好,新梢长和基部粗分别为142.5cm和2.5cm。在砧木粗时采用此方法最好。6月底进行了方块芽接不同剪砧高度处理试验,结果表明:接芽上方留一叶片剪砧成活率最高,达85%,是方块芽接最佳剪砧高度。
With 2-year-old walnut seedlings as the rootstock, Liao nuclear 3 as a scion, in Qingshui County in mid April on the tongue, cut the tongue, affixed, split, cut and other five kinds of branch connection test results show : The highest survival rate of paste, up to 78%, is the preferred method of grafting walnut seedlings Qingshui. Tongue tongue access survival rate was 62%, nursery stock the best quality, shoot length and basal coarse 142.5cm and 2.5cm respectively. This method is best when crude stock is rough. At the end of June, we carried out the test of the height treatment of different shearing anvil with square budding. The results showed that the highest survival rate was 85%, which was the best shear anvil height of square budding.
