我区河套地区盛产各种梨类水果,杜梨是嫁接梨属果树的最好砧木。其特点是抗寒、耐盐碱、亲和力强、树势健壮。对比试验表明,采用当地杜梨种子育苗,出苗整齐,生长迅速。在同样的土壤条件下,当地杜梨种子培育的苗木比外地引进的种子育的苗质量好,苗高、苗壮、移植后成活率高。因此,为发展优良品种梨的嫁接生产,有必要增加当地杜梨实生苗的培育。具体措施有以下几点; 一、采种当地杜梨一般在6年生时开始结果。果实于10月中
Hetao area in my area is rich in all kinds of pear fruits, pear is the best pear rootstock grafting. It is characterized by cold, salt, affinity, strong tree vigor. Comparative tests show that the use of local seedlings of pear seedlings, emergent tidy, rapid growth. Under the same soil conditions, the seedlings nurtured by the local pear seed had better quality, higher seedling density and better seedling survival rate than those introduced from other places. Therefore, in order to develop grafted pear production, it is necessary to increase the cultivation of local pear seedlings. The specific measures are the following: First, the local planting pear DuPont generally start the result at 6 years. The fruit is in mid-October
