橡胶树工厂化繁育技术优化与改进

Optimization and Improvement of Rubber Tree Breeding Technology

对橡胶树良种苗木工厂化繁育过程中的育苗容器规格、定植密度、芽条增殖方式、籽苗芽接苗抽芽促进技术以及苗木抚管等方面进行了研究。结果表明:直径7.5cm,高30cm的半硬质塑料杯是最好的育苗容器;苗木定植密度以计划密植较好;小型绿色芽条批量化增殖技术是工厂化育苗最适应的芽条增殖方式;使用化合物A100mg/L+6-BA40mg/L+GA310mg/L涂抹芽片,可有效促进抽芽;使用0.2%螯合铁灌根1-3次,可以解决橡胶树工厂化繁育过程中普遍出现的苗木缺铁黄化问题。经过优化与改进,橡胶树工厂化繁育技术的规范性、可操作性和稳定性均得到了提高。

This article studies seedlings of rubber tree seeds during the breeding factory nursery, container size, planting density, the way of proliferation of buds, the technology of budding seedlings and sprouting seedlings and saplings as well as management, etc. The results showed that： Diameter of 7.5cm, 30cm high semi-rigid plastic cup is the best nursery containers; Close planting seedling planting density to plan better; Small green buds of the mass proliferation of technology is the most industrialized breeding methods to adapt to the proliferation of buds; Use compound A100mg / 1 ＋6- BA40mg / 1 ＋ NAA10mg / 1 film coated bud, which can effectively promote budding; 0.2% chelated iron irrigating using 1 to 3 times, can solve the breeding factory rubber tree seedlings during the prevalence of iron deficiency yellowing problem. After the optimization and improvement of the rubber tree breeding technology, factory specifications, operability and stability are improved.
