Problems solved by technology

Among the three grafting techniques, conventional grafting has the lowest survival rate, and seedling grafting has the highest survival rate. However, the process of grafting seedlings is longer and the management is complicated. In recent years, the growth has been weak and the initial flowering period has been longer, which is not as good as conventional grafting and big tree grafting. High-grain transplants grow quickly, and the initial flowering period is short

Embodiment 1

[0024] Choose 13-year-old Camellia oleifera as the rootstock. Before grafting, trim the rootstock, select 3 main branches that are evenly distributed, and trim the main branches to a height suitable for grafting. Remove all other branches, and sterilize and seal the cuts . From the eighteen bachelor camellias with good genetics, pure varieties, strong growth, and no pests, select 8cm new shoots that have been lignified this year, with full leaf buds and buds, as scions. The new shoots contain 2 pieces that have been cut off 1 / 2 of the leaves, then cut the new shoot interface into a wedge shape, and remove 1 / 4 of the cortex.

[0025] Using the cutting method, the cambium of the grafted main branch is closely attached to the cambium of the scion, and the joint of the scion and the main branch is tightly bonded with a plastic strip, and then covered with a moisturizing cover, and the rootstock is protected from the shade. Prevent moisture from evaporating. After 3 months, the n...

Embodiment 2

[0029] Choose 18-year-old Camellia oleifera as the rootstock. Before grafting, trim the rootstock, select 2 main branches that are evenly distributed, and trim the main branches to a height suitable for grafting. Remove all other branches, and sterilize and seal the cuts . From the eighteen bachelor camellias with good genetics, pure varieties, strong growth, and no pests, select 5cm new shoots that have been lignified, full of leaf buds, and buds that were born this year as scions. The new shoots contain 1 piece that has been cut off 1 / 3 of the leaves, then cut the new shoot interface into a wedge shape, and remove 1 / 3 of the cortex.

[0030] Using the skin-lifting method, the cambium of the grafted main branch is closely attached to the cambium of the scion, and the bonding part of the scion and the main branch is tightly bonded with a plastic strip, and then covered with a moisturizing cover, and the rootstock is shaded. , prevent moisture from evaporating. After 2 months...

Embodiment 3

[0034] Choose 2-year-old slate wood as the rootstock. Before grafting, trim the rootstock, select 2 main branches that are evenly distributed, and trim the main branches to a height suitable for grafting. Remove all other branches, and sterilize and seal the cut . From the eighteen bachelor camellias with good genetics, pure varieties, strong growth, and no pests, select new shoots of 5-8cm that have been lignified this year, with full leaf buds and buds, as scions. The new shoots contain 2 pieces of Cut off 1 / 3 of the leaves, then cut the new shoot interface into a wedge shape, and remove 1 / 4 of the cortex.

[0035] The cambium of the grafted main branch is closely attached to the cambium of the scion by using the abdominal grafting method, and the joint of the scion and the main branch is tightly bonded with a plastic strip, and then covered with a moisturizing cover, and the rootstock is protected from the shade. Prevent moisture from evaporating. After 2 months, the new ...

Abstract

The invention discloses a top grafting method for camellia 'Shibaxueshi'. The camellia 'Shibaxueshi' with high graft survival rate and low preparation cost is obtained through selecting proper rootstock and enabling the proper rootstock to be matched with a simple grafting technique and an optimized cultivation method. The method comprises the specific preparation steps of selecting 13-18-years-old live oil-tea camellia and 2-3-years-old Tutcheria spectabilis Dunn as the rootstock, selecting young sprouts, grown in the present year, from robust camellia 'Shibaxueshi', grafting by adopting a cut grafting, side grafting or peeled grafting method, optimizing cultivation details before / with / after grafting, and finally, carrying out fertilization and deinsectization, thereby obtaining the camellia 'Shibaxueshi' capable of flowering earlier, wherein the graft survival rate is high.

Description

Technical field: [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a method for high-position grafting of eighteen bachelor camellias. Background technique: [0002] Camellia belongs to the evergreen broad-leaved shrubs of the family Theaceae. It is one of the top ten famous flowers in my country and one of the famous flowers in the world. Camellia is also known as camellia, winter-resistant flower, and mandala.
