摘要
金花茶具有较高的观赏价值和经济价值,但生长较慢,实生苗或扦插苗几年内难以长成冠大、枝粗、花量大的植株。油茶老树桩由于品种和树龄的关系,其产油量较低,经济价值较低。以油茶老树桩为砧木,选用优良品系的金花茶枝条作为接穗,应用大树换冠嫁接技术,充分发挥油茶老桩原有根系和粗壮枝干的优势,快速培养出生长快、树冠大、树形美、开花快、花量大的金花茶大规格植株。此技术缩短了金花茶大规格植株的培育周期,保持了金花茶母株的优良性状,有效提高了油茶老树桩的经济价值,对金花茶产业优化发展具有较好的推动作用。
The golden camellia tea has high ornamental value and economic value, but it is slow to grow, and it is difficult for seedlings or cuttings to grow into large, thick and flowered plants in a few years. Because of the relationship between variety and tree age, the old tree stump has low oil production and low economic value. In oil-tea old stump for stocks and gold choose superior strains of scented tea branches as a scion, application of trees in crown grafting technology, give full play to the old pile original roots and thick branches of the advantage, quickly develop fast growth, large canopy, tree fast beauty, flowering and spend large amount of gold scented tea with large plants. This technique shortens the gold scented tea, large size of the plant breeding cycle to keep the good character of gold scented tea plant, effectively improve the economic value of camellia old stump, optimization of gold scented tea industry has a good role in promoting.
