按常规育苗,秋季芽接,第二年出圃,周期长,不利于经济利用土地;且苗木高大,不利于矮化密植。1992年我们进行李树绿枝嫁接育苗试验,6月24日进行嫁接的,当年全部成苗,一级苗占80％,二级苗占20％。苗高、茎粗、侧根数与粗度均达到苗木质量要求,嫁接口愈合良好,整形带内芽眼饱满。 1991年夏天采集毛樱桃种子,洗净后与湿沙拌匀,埋入40厘米深的土壤中层积,1992年春土壤解冻后取出已刚萌芽的种子,及早播种,出苗后加强前期管理。6月下旬,采优良李树当年已半木质化的新梢做接穗,采用
According to the conventional nursery, autumn budding, the second year of nursery, long cycle, is not conducive to economic use of land; and seedlings tall, is not conducive to dwarf and close planting. In 1992, we carried out the experiment of grafting seedlings of Li Shugu sticks and grafting on June 24, when all the seedlings were grafted, 80% of the first seedlings and 20% of the second seedlings. Seedling height, stem diameter, lateral root number and thickness of nursery stock have reached the quality requirements, good healing of graft interface, full plastic bud with buds. In the summer of 1991, the seeds were collected, washed and mixed with wet sand. The soil was embedded in a layer of soil with a depth of 40 cm. After the soil was thawed in the spring of 1992, the newly germinated seeds were taken out and planted as early as possible. In late June, good plum tree has been half-limed new shoots scion, use
