油茶嫁接苗培育移苗拼床技术研究

study on Transplanting Technique of camellia oleifera Grafted seedlings

摘要:

为进一步提高育苗质量,对一年生油茶嫁接苗进行不同移苗拼床处理,通过对成活率、苗高、地径和分枝数等 指标调查分析。 结果表明:苗木采取分级和间隔拼床能取得较好的效果。 针对一级苗采取 FDP1处理拼床后成活率达 90. 00%,苗木高度达 63. 20 cm,地径达 5. 40 mm,分枝数为 2. 0 枝 ; 采取 FBP1处理成活率达 83. 33%,苗木高度达 67. 40cm,地径达 5. 95mm,分枝数为 1. 87枝;针对二级苗可采取 FDP2处理,成活率达80. 00%,苗木高度达 45. 33cm。

Abstract:

In order to improve seedlings quality, we studyied the survival rate, seedling height, basal diameter and branches by transplanting one—year grafted seedlings of camellia oleifera . The results showed that seedling classification and spaced trans- plantation could get good results . For the first—class seedlings, the survival rate could reach 90. 00% , and the seedlings height could reach 63. 20cm, and the diameter could reach 5. 40mm, and the branches could reach 2. 0by adopting the FDP1method; By adopting the FBP1method, the survival rate could reach 83. 33% , and the seedlings height could reach 67. 40cm, and the diameter could reach 5. 95mm, and the branches could reach 1. 87. For the second—class seedlings, the survival rate could reach 80. 00% and the seedling height could reach 45. 33cm by taking the FDP2method.
