Method for improving top-grafting survival rate of camellia trees
A high-level grafting and survival rate technology, applied in the field of plant cultivation, can solve the problems of lower grafting survival rate and preservation rate, rootstocks are easily burned by sunlight, and reduction of forest canopy density, so as to achieve high scion survival rate and preservation rate, effective It is beneficial to the growth of scion and reduces the effect of nutrient and water loss

Embodiment 1
[0024] From May to June 2009, crown grafting was carried out in Tongfu Village, Toupai Town, Jinxiu County, Guangxi. Select 20-year-old Camellia oleifera trees, and select 2 branches of Camellia oleifera trees that are evenly distributed and grow robustly as rootstocks on each Camellia oleifera tree. Saw off with a saw at the smooth place where the selected Camellia oleifera branches are 40cm to 50cm above the ground, and at the same time saw off all the remaining branches from the base of the branches with a saw, without retaining vegetative branches and shade branches.
[0025] Collect 0.2-0.3cm-thick semi-lignified and normal-growing scion in the middle and upper part of the canopy of a fine Camellia oleifera variety as the scion, cut the scion to a length of 2-3cm, and keep one bud and one leaf. If the leaf is too large, you can cut off 1 / 2 3 blades. Grafting is carried out by the conventional method of skin-lifting and grafting, and the scion and the rootstock branch are...
Embodiment 2
[0028] On a sunny day in June 2009, we carried out crown grafting of big Camellia oleifera trees in Bamiao Village, Bamiao Village, Yufeng Town, Tianyang County, Guangxi. Select 25-year-old Camellia oleifera trees, and select 3 branches of Camellia oleifera trees that are evenly distributed and grow robustly as rootstocks on each Camellia oleifera tree. Saw off with a saw at the smooth place where the selected Camellia oleifera branches are 60cm to 70cm above the ground, and at the same time saw off all the remaining branches from the base of the branches with a saw, without retaining vegetative branches and shade branches.
[0029] Collect the 0.2-0.3cm-thick lignified and normal-growing scion from the middle and upper part of the canopy of the excellent Camellia oleifera variety as the scion, and cut the surface of the scion to a length of 2-3cm, and keep one bud and one leaf. If the leaves are too large, cut off 1 / 2 of the leaves. Grafting is carried out by the conventiona...
Embodiment 3
[0032]On a sunny day in July 2016, the crown grafting of Camellia oleifera trees was carried out in Bada Town, Xilin County, Guangxi. Choose 30-year-old Camellia oleifera trees, and select 4 Camellia oleifera branches that are evenly distributed and grow robustly as rootstocks on each Camellia oleifera tree. Saw off with a saw at the smooth place where the selected Camellia oleifera branches are 70cm to 80cm above the ground, and at the same time saw off all the remaining branches from the base of the branches with a saw, without retaining vegetative branches and shade branches.
[0033] Collect 0.2-0.3cm-thick semi-lignified and normal-growing scion in the middle and upper part of the canopy of a fine Camellia oleifera variety as the scion, cut the scion to a length of 2-3cm, and keep one bud and one leaf. If the leaf is too large, you can cut off 1 / 2 3 blades. Grafting is carried out by the conventional method of skin-lifting and grafting, and the scion and the rootstock br...
