Method for raising seedlings by grafting Lithocarpus pachylepis nuts

Abstract

The invention discloses a method for raising seedlings by grafting Lithocarpus pachylepis nuts. According to the method, the fine characters of female parents of fruit trees are maintained, and buds or branches of a fine breed of the Lithocarpus pachylepis are grafted on a rootstock having affinity, so that grown plants of scions can keep the fine characters of the female parents, and the plants grow and fruit uniformly. The genetic characters of the fine clone breed of the Lithocarpus pachylepis are stable, and the variation of the Lithocarpus pachylepis does not occur, so that the fine characters of the female parents can be maintained; the high yield in the early stage is achieved; as the scions used for grafting of Lithocarpus pachylepis seedlings are all the branches and buds adoptedfrom preferential adult trees and grafted on the rootstock, survival branches have the development characteristics of the adult trees, so that the breeding cycle can be shortened, the full productiveage of the adult trees can come in advance, and the early harvest effect can be achieved for Lithocarpus pachylepis fruits; the shape of the trees is changed, the Lithocarpus pachylepis fruits are arbor seeds, and the trees are enabled to grow shortly, small and compactly by dwarfing the plants, so that the utilization rate of land is improved.

Description

technical field [0001] The invention relates to the field of grafting nuts of Yishenzi, in particular to a method for grafting and raising seedlings of nuts of Yishenzi. Background technique [0002] Yishenziguo belongs to the species of evergreen broad-leaved trees, suitable for planting in tropical and subtropical evergreen broad-leaved forest areas. It grows fast, has strong resistance, and has wide requirements on climate and soil environment. However, at present, most of the Yishenzi orchards built on a large scale in various places are dominated by seedlings, resulting in poor stand quality and serious seedling differentiation, which directly affects fruit yield and product quality, and stand improvement is urgently needed. The lack of improved varieties and unmatched cultivation techniques are the key factors restricting the development of the new industry of Yishenzi fruit forest. [0003] The wild Yishenzi varieties are good and bad, and they are easy to damage the...

AI Technical Summary

Problems solved by technology

[0003] The wild Yishenzi varieties are good and bad, and they are easy to damage the root system in the process of excavation, transportation, sales, etc., resulting in different sizes and uneven yields of the Yishenzi plants planted on the market

However, the fruit trees grown directly by seed sowing will easily lose the good characters of the original Yishen sub-variety.

Because the Yishenzi fruit tree is a cross-pollination plant, when cross-pollination results in the tree having the genetic characteristics of both parents, the offspring are prone to segregation of traits, with mixed performance and loss of the consistency of the original mother plant variety

The resulting seeds are heterozygous, and the excellent characteristics of the female parent cannot be maintained by sowing seeds
