桃树根枝嫁接可以减少育砧环节,接苗直接定植比苗圃生长更快,进行集约管理,第二年可结果,第三年能丰产。现介绍其技术要点。一、砧根收集。在桃苗出圃时或桃园冬季深翻时,收集桃苗或5年生以内桃树的根系,选取须根多、无病虫、未损伤、直径0.5～1.5厘米的作砧根。把砧根捆成小把,置于室内湿沙坑中埋藏备用。坑内沙的湿度宜保持手捏成团手松即散的状态。
Peach root grafting can reduce the part of the breeding ancestors, seedling transplanting directly than nursery growth faster, intensive management, the second year results, the third year of high yield. Now introduce its technical points. First, the root anvil collection. When peach nursery or peach deep plowing in winter, the peach or perennial peach roots collected within 5 years, select the fibrous root, no pests, no damage, 0.5-1.5 cm in diameter for the rootstock. The anvil root bundle into small, placed in the indoor wet sand pit buried reserve. The moisture in the pit should be kept in a state of loose hands and loose hands.
