葡萄的繁殖方法,多数采用春季硬枝扦插繁殖,但在水源缺乏的干旱山区成活率很低。如果采用夏季环剥套袋繁殖,生根率在95%以上,移栽成活率也可达95%以上。这种繁殖方法具有不受条件限制、操作简单、成活率高.结果早等特点。具体操作方法如下:套袋繁殖在7月上旬至8月中旬都能进行。套袋时选葡萄架中上部生长健壮、密集多余的当年生新枝(已经木质化的为好),先将幼嫩的心摘掉,并除去叶腋间的副梢和卷须。再在第7—8片叶子
Grape breeding methods, the majority of spring hardwood cutting propagation, but poor water in the arid mountain survival rate is very low. If the use of summer circumcision bag breeding, rooting rate of 95% or more, transplanting survival rate of up to 95%. This breeding method has the advantages of free from restrictions, simple operation and high survival rate. Specific methods of operation are as follows: Bagging breeding in early July to mid August can be carried out. Bag when the election elected to grow in the upper part of the robust, dense extraordinarily new branches (already lignified as well), the first young heart off, and remove the leaf axillary adducts and tendrils. Then in the first 7-8 leaves
