Embodiment 1

[0026] The 1-year-old seedlings of Phoebe fukiensis with robust growth, seedling height of 50-60 cm, ground diameter of 6-7 mm were selected as rootstocks for grafting. Among the excellent provenances, according to the standard ground method, select excellent trees with straight trunks and good growth with a tree height greater than 15% of the average tree and a breast diameter greater than 50% of the average tree as the mother tree for fringing; Semi-lignified branches with base diameter greater than or equal to 4.5mm. After cleaning and disinfecting the collected scions with sterilizing solution according to the conventional method, cut them according to the scion length of 4-5 cm and more than two bud eyes, and remove all the leaves on each scion. Cut one knife each, and cut the lower end into a wedge shape. The length of the knife edge is about 1-1.5 cm. The trimmed scion is wrapped with a clean wet towel. Trim the scion while trimming and grafting to prevent dehydration ...

Embodiment 2

[0028] The 1-year-old seedlings of Phoebe fukiensis with robust growth, seedling height of 40-50 cm, ground diameter of 5-6 mm were selected as rootstocks for grafting. Among the excellent provenances, according to the standard ground method, select excellent trees with straight trunks and good growth with a tree height greater than 15% of the average tree and a breast diameter greater than 50% of the average tree as the mother tree for fringing; Semi-lignified or just mature branches with a base diameter greater than 4.5 mm. After cleaning and disinfecting the collected scions with sterilizing solution according to the conventional method, cut them according to the scion length of 5-6 cm and more than two bud eyes, and remove all the leaves on each scion. Cut one knife each, and cut the lower end into a wedge shape. The length of the knife edge is about 1.5-2 cm. Wrap the trimmed scion with a clean wet towel. Scion pruning should be grafted in time to prevent dehydration fro...

Abstract

The invention discloses a phoebe bournei grafting and seedling raising method. Strong one-year phoebe bournei seedlings with the height of 40-60 cm and the ground diameter of 5-7 mm are selected as rootstock, in-season sprouting branches are selected from good provenance select trees with the height 15% larger than average height and the diameter at breast height 50% larger than average diameter at breast height or more to serve as scions, after grafting, the rootstock and the scions are prevented from being bruised or tilted and broken, sprouts are removed, bound mulching films are cut open in time, fertilizer and water management, weeding and disease and pest prevention are conducted well in time during the period, and good strong phoebe bournei grafting seedlings are obtained. The seedling raising method is easy and quick to operate, the grafting survival rate is high, new seed collecting mother plant dwarf can be promoted, the flowering and fruiting stages are earlier, safety of manual seed and cutting collection is improved, production cost is reduced, fecundity of good phoebe bournei seedlings is improved, good seed supply capacity is improved, and the requirements of development of the phoebe bournei industry are met.

Description

technical field [0001] The invention relates to the technical field of forestry plant cultivation, in particular to a method for growing seedlings by grafting Nannan. Background technique [0002] Fujian Nan ( Phoebe bournei ) is known for its excellent material quality, and is a unique and precious timber tree species in my country, which is a national second-level key protected plant. For a long time, people's over-harvesting and utilization of Minnan in natural forests, as well as greater environmental pressure have led to a very low seed germination rate and seedling survival rate in the wild, resulting in a decrease in the natural population of Minnan and a sharp decline in the quality of Minnan resources; another On the one hand, people do not pay enough attention to the artificial cultivation of Nannan, which leads to the shortage of Nannan resources and a serious shortage of reserve resources. In order to protect the germplasm resources of this tree species, expand...
