Guangnan County, Yunnan Province, has developed a new technology for the anvil grafting of camellia oleifera with hard branches

Yunnan Netnews (reporter Huang Peng correspondent Zhou Lai) Relying on the technical support of the Yunnan Academy of Forestry and Grassland Sciences Oil Tea Research Institute, after 10 years of research, Guangnan County has developed the anvil grafting technology of oil tea hard branch bud seedlings, which solves the key technical bottleneck of the cultivation of fine seedlings with low survival rate, high cost and long cycle of oil tea grafting.

Recently, the reporter saw in the laboratory of the Institute of Oil Tea of the Yunnan Academy of Forestry and Grassland Sciences in Guangnan County that skilled workers are grafting camellia oleifera at a rate of 3,000 trees per day, and this efficient seedling fast propagation technology is the anvil grafting technology of the hard branches of oil tea seedlings, at the same time, by segmenting the anvil of the bud seedlings, from the previous only one can be grafted to the present can graft multiple trees, which greatly reduces the production cost.

"Previously, only one tree could be grafted, but now three can be grafted." Chen Fu, director of the Institute of Camellia Oleifera of Yunnan Academy of Forestry and Grassland Sciences, introduced that the original can only graft camellia oleifera seedlings in June every year, through the use of sterile soil substrate cultivation, and in the control of shading, temperature and humidity to work hard, after 13 processes, can be grafted all year round, staggered the peak of grafting, reducing the risk of seedling cultivation.

With the successful research and development of anvil grafting technology of camellia oleifera hard branch bud seedlings, the technology began to be applied on a large scale in Yunnan Dongchang Agriculture and Forestry Product Development Co., Ltd. this year, effectively solving a series of technical problems such as insufficient seedling cultivation and high production management costs of the company. "The survival rate can reach more than 95%." Chen Fu said that the use of oil tea hard shoot shoot seedling anvil grafting technology, the seedlings are robust, the root system is more developed, the traditional young shoot shoot seedling anvil grafting technology was used before, it takes two years, and now it only takes one year to cultivate the seedlings with the hard branch bud seedling anvil technology.
