本文对葡萄绿枝嫁接换头技术进行了研究。结果表明,主蔓距地面5～10cm短截后进行嫁接成活率较高为87%,且长势较好;塑料布包扎接穗上端保湿和整个接穗套塑料袋保湿效果差异不明显,从操作简单易行的角度出发,建议用塑料布包扎接穗顶部的方式进行保湿;对于嫁接后的管理,建议前期施氮肥为主,后期适当控制浇水,后期施肥以磷钾肥为主,同时及时除去砧木上的萌蘖。
In this paper, grafting techniques for grape green branches were studied. The results showed that the survival rate of grafting from 5 cm to 10 cm short stubble on the ground was 87% higher than that on the ground, and the growth rate was good. The moisture retention effect of plastic wrap at the upper end of the scion and the entire scion wrap was insignificant. For the management after grafting, it is suggested that nitrogen should be predominated in the early stage and water should be properly controlled in the late stage. Phosphorus and potassium fertilizer should be applied mainly in the later stage of fertilization, and the rootstock should be timely removed Sprout.
