Problems solved by technology

[0004] About 60% of the existing camellia oleifera forests in my country belong to low-yield and low-efficiency forests. Therefore, a considerable part of the low-yield forests need to be transformed. One of the most common transformation measures is to carry out high-inoculation and replacement, that is, in the low-yield forests, the Camellia oleifera trees are smaller. Grafting is used to replace high-quality Camellia oleifera varieties in the high parts, so as to quickly realize the replacement and increase the yield. However, in the specific transformation process of Camellia oleifera varieties, due to various reasons, a considerable number of low-yield Camellia oleifera forests were abandoned and eliminated, resulting in huge waste of resources

Embodiment 1

[0056] (1) Camellia oleifera excavation and root selection

[0057] ① Nursery preparation: In the middle and late March of 2012, choose a plot with flat terrain, leeward to the sun, and good drainage and irrigation as a bonsai cultivation and placement nursery; the width of the trail is 40cm, the width of the furrow is 1.2m, and the length of the furrow is based on the terrain. Ditching on the spot drain;

[0058] ② Build a shade shed: build a shade shed on the prepared nursery ground for shade, the height of the shade shed is 2.0-2.5m, and the shade degree is 75-80%;

[0059] ③Excavation time: Excavation will be carried out from late May to early August;

[0060] Excavation is to remove all the parts above the ground diameter of the camellia oleifera, leaving only all the roots below the ground diameter; the bare roots of the excavated tree roots do not have mud, and the original main root length and as many side roots of the camellia oleifera itself are kept as much as poss...

[0090] (1) Camellia oleifera excavation and root selection

[0091] ① Nursery site preparation: In the middle and late May of 2013, choose a plot with flat terrain, leeward to the sun, and good drainage and irrigation as a bonsai cultivation and placement nursery site; the width of the trail is 40cm, the width of the border is 1.2m, and the length of the border is based on the terrain. Ditching on the spot drain;

[0092] ② Build a shade shed: build a shade shed on the prepared nursery ground for shade, the height of the shade shed is 2.0-2.5m, and the shade degree is 75-80%;

[0093] ③Excavation time: Excavation will be carried out from late July to early October;

[0094] Excavation is to remove all the parts above the ground diameter of the camellia oleifera, leaving only all the roots below the ground diameter; the bare roots of the excavated tree roots do not have mud, and the original main root length and as many side roots of the camellia oleifera itself are kept as mu...

[0124] (1) Camellia oleifera excavation and root selection

[0125] ① Nursery site preparation: In the middle and late July of 2014, choose a plot with flat terrain, leeward to the sun, and good drainage and irrigation as a bonsai cultivation and placement nursery; the width of the trail is 40cm, the width of the border is 1.2m, and the length of the border is based on the terrain. Ditching on the spot drain;

[0126] ② Build a shade shed: build a shade shed on the prepared nursery ground for shade, the height of the shade shed is 2.0-2.5m, and the shade degree is 75-80%;

[0127] ③Excavation time: Excavation will be carried out from late August to early October;

[0128] Excavation is to remove all the parts above the ground diameter of the camellia oleifera, leaving only all the roots below the ground diameter; the bare roots of the excavated roots do not have mud, and the original main root length and as many lateral roots of the camellia oleifera itself are kept as much a...

Abstract

The invention discloses a method for cultivating camellia bonsai by a two-step grafting method of Camellia oleifera roots, which includes digging Camellia oleifera and selecting roots, the first step of grafting, putting in pots, promoting germination and promoting shoots, the second step of grafting, management and In the shaping and pruning process, suitable roots of camellia oleifera are selected as grafting rootstocks, and camellia plant branches are collected as grafting scions, and the first step of grafting is carried out by cutting grafting. When the scions grafted in the first step survive for more than 6 months, the camellias are collected The plant branch is used as the grafted scion, and the new shoots drawn from the scion grafted alive in the first step are used as the rootstock for grafting, and the split grafting method is used to carry out the second step of grafting. After management, the grafted camellias are trimmed according to the ideal shape of the bonsai. The invention adopts the root grafting of camellia oleifera to realize fast replanting of low-yield camellia oleifera forest, promotes the existing large-area low-yield camellia oleifera forest transformation project in China, reduces waste of resources, and has strong ornamental value.

Description

technical field [0001] The invention relates to the field of grafting of economic forest species, in particular to a method for cultivating camellia bonsai by two-step grafting of camellia oleifera roots. Background technique [0002] my country is the distribution center of Camellia plants and has extremely rich camellia germplasm resources. The majority of camellia lovers select and breed variants (such as bud change and leaf change) from the seedlings of the original species of camellia, and also through natural hybridization, artificial Hybridization and other means have created many new varieties of camellia with excellent ornamental properties. Camellia plants have a variety of colors and are gorgeous, and the flowering period coincides with traditional festivals such as New Year’s Day, Spring Festival, and Lantern Festival. More and more camellia plants are used for landscaping and landscaping, among which camellia bonsai with high economic value are gradually enterin...
