Abstract

The invention relates to the field of forest improved variety seed orchard cultivation, in particular to a method for constructing a single-stock multi-variety liquidambar formosana hance seed orchard. The method comprises the steps that a liquidambar formosana hance rootstock planted for one year is subjected to ultra-low-position trunk cutting and stump reserving, low-position bud germination promoting, multi-coppice-shoot fixed-angle cultivation and low-position coppice shoot multi-variety grafting; and a growth regulator is sprayed to scions with weak growth vigor after grafting survival,and balanced growth of the scions is promoted. By implementing the method, the liquidambar formosana hance rootstock is subjected to low-position trunk cutting and stump reserving and germination promoting, three robust coppice shoots are reserved and cultivated in each stump, one variety is grafted to each coppice shoot, and the liquidambar formosana hance seed orchard with multiple strains on one seed tree is formed. Therefore, the number of strains in the seed orchard per unit area can be effectively increased, the genetic diversity of the seed orchard is improved, and the heterozygosity ofproduced seeds is promoted; and meanwhile, when the quantity of the configuration strains of the seed orchard is consistent, the orchard building area can be remarkably reduced, and the forest management investment is reduced.

Description

technical field

[0001] The invention relates to the field of forest tree seed orchard cultivation, in particular to a method for constructing a single rootstock and multi-variety liquidambar seed orchard. Background technique

[0002] Liquidambar ( Liquidambar formosana Hance. ) is a tall deciduous tree of the genus Liquidambar in the family Hamameliaceae Liquidambariae. It has high application value in wood, medicine, pad dyeing, edible fungus cultivation and other methods. It has attracted much attention in production and scientific research. It is one of the first choice tree species for plantation tree species structure adjustment, and it is also a potential garden ornamental greening tree species. .

[0003] In recent years, with the advancement of the adjustment of forest tree species structure, the vacancy of native broad-leaved tree species needs to be filled urgently, and the construction of seed orchards is imminent. Traditional liquidambar seed orchards are bu...
