Camellia is one of the major woody oils in southern China, but due to extensive management, most of them are in low-yield conditions. In order to increase the yield of Camellia oleifera, many years of application trials in Hunan Province have shown that using GGR cuttings to raise seedlings and rooting in advance, the rooting rate reaches 100%, the survival rate increases by 91%, and the root system is developed. Application of GGR to oilseed grafting of Camellia oleifera can promote the growth of roots of seedlings, increase graft survival rate by 15%, and nursery trees can be planted and afforested earlier, increasing the rate of nursery and nursery use by 35%. The application of GGR for afforestation increased the survival rate by 32%. At the same time, it increased the degree of rooting, branching, and high growth in different degrees, and could promote the early flowering of Camellia. The application of GGR preserved fruits can increase the Fruit rate of oil tea, reduce fruit drop, and increase the yield of oil tea. The specific application method is as follows:
1. Application method of GGR in tea seedling cutting and cutting seedlings: Treat oleifera twigs with GGR No. 6 50 mg.kg-1 for 1.5 hours, then use this solution to mix yellow mud packs and cut them in the shade under plastic film-covered containers. 1g of GGR can handle 4000 cuttings.
2. Application method of GGR in the grafting of oil tea bud seedlings: grafting with 0.5 ml of GGR6 and soaking buds for 0.5-1 hour. One gram of GGR can handle 1 acre oil tea grafted seedlings.
3. Application method of GGR for grafting and reshaping of Camellia oleifera trees: Grafting with GGR6 No. 50ppm for 1-2 hours after grafting. It can improve the survival rate of the crown of a tree, and it can treat 4000 branches per gram of GGR.
4. Application of GGR in Camellia afforestation: The application of GGR No. 6 100ppm plutonium mud for afforestation or bare-rooted afforestation can increase the survival rate of afforestation.
5. Application of GGR on Camellia saccharifolia cultivars: Application of GGR 6 No. 20 ppm was carried out on foliar sprays during the flowering period of Camellia oleifera and fruit enlargement. It can increase the fruit rate of camellia, the rate of seed production, and increase the yield of tea fruit.
