建立采穗圃,砧木以核桃共砧嫁接成活率最高;各品种间嫁接成活率无显著差异。用于芽接的砧木以长势中庸为好,长势过旺者嫁接成活率极低;芽接应在砧木达到要求粗度、接芽成熟时越早越好,应在雨季来临的6月2 0日之前完成嫁接,最晚不能超过6月3 0日;要合理选择穗枝、及时摘心以提高接芽的利用率;嫁接前后各7d内要严禁圃地浇水,并注意当地气象台中期气象信息,合理把握嫁接时机。
The establishment of ear-picking nursery, rootstocks to walnut common anvil grafting survival rate was the highest; grafting survival rate between the varieties no significant difference. Rootstock used for budding to the growth of the median as well, the growth of over-grafting survival rate is very low; budding should be required in the rootstock roughness, the bud as soon as possible the maturity of the better, should be in the rainy season before June 20 To complete the grafting, the latest can not exceed June 30; to choose a reasonable branch, in time topping in order to improve the utilization rate of access buds; before and after grafting within 7d to prohibit watering the garden, and pay attention to the local meteorological meteorological information, reasonable Grasp the timing of grafting.
