牡丹栽培多采用播种、分株和嫁接法。播种繁殖不能保持原品种的特性,一般作为杂交育种,培育砧木和选育新品种,不宜作为商品流入市场。分株法虽能保持原品种的特性,但繁殖系数低,投资成本高,苗木高矮大小不一,难以适应商品化、规格化生产的需要。嫁接法能较好地克服分株法和播种法的缺点,不仅能保持原优良品种的特性,而且繁殖系数大,苗木整齐一致,成活率高,投资成本少。因此在牡丹生产中被广泛运用。
Peony cultivation and more use of sowing, ramets and grafting. Seeding and breeding can not maintain the characteristics of the original breed, generally as hybrid breeding, breeding stock and breeding new varieties, not as a commodity into the market. Although the ramets can maintain the characteristics of the original varieties, but the low coefficient of multiplication, high investment costs, the height of seedlings vary in size, difficult to adapt to commercialization, standardized production needs. Grafting method can better overcome the shortcomings of seeding method and sowing method, not only to maintain the characteristics of the original fine varieties, and breeding coefficient, neat and consistent seedlings, high survival rate, low investment costs. Therefore, peony production is widely used.
