Rejuvenation method of short-branch casuarina equisetifolia mature woods

Abstract

The invention relates to a rejuvenation method of short-branch casuarina equisetifolia mature woods. The method comprises the steps that short-branch casuarina equisetifolia branches are cut from theshort-branch casuarina equisetifolia mature woods, tender branchlets on the branches are cut off, and the branches serve as scion branches; short-branch casuarina equisetifolia seedlings serve as stocks, the scion branches are grafted to the stocks through a cut-grafting method or a cut-attachment grafting method, then the scion branches and the stocks are bound through sealing films, and the scion branches are wrapped; and the sealing films wrapping the scion branches are coated with wax layers. According to the rejuvenation method of the short-branch casuarina equisetifolia mature woods, excellent germplasm resource rejuvenation is achieved through the cut-attachment grafting method or the cut-grafting method, sealing is conducted in a sealing film wrapping and waxing mode, connector moisture losses can be reduced, rapid formation of calluses is promoted, outside influences such as morning fog and insects and ants can be effectively avoided, the rejuvenation survival rate of mature short-branch casuarina equisetifolia trees is increased to 70% or above, adopted wax can be common household candles or industrial paraffin, the cost is low, and operation is easy and fast.

Description

technical field [0001] The invention relates to the field of forest tree genetics and breeding, in particular to a method for juvenile short-branch casuarina mature forest trees. Background technique [0002] Casuarina is wind-resistant, resistant to barrenness, and has good biological characteristics. It is a pioneer tree species for building tropical and subtropical coastal shelter forests. In some front sandy areas with poor site conditions, casuarina is even the only tree species that can be used for afforestation. In my country, casuarina is widely distributed in the coastal areas of South China. It has important uses such as resisting typhoon, protecting farmland and cities, and restoring vegetation. It is known as the "Green Great Wall" along the coast of South China. Among them, Casuarina equisetifolia is the main tree species of Casuarina species, and its planting area accounts for more than 80% of the total Casuarina planting area in China. [0003] The systemati...

Problems solved by technology

Traditional tree grafting methods can preserve materials with target traits to a certain extent, but they are affected by complex field environmental factors during scion transportation and storage, grafting, and post-management, which makes the survival rate of grafting low and the preservation of high-quality tree materials is not comprehensive; In particular, short-branched casuarinas, as an introduced tree species, are relatively rare in high-quality resources and difficult to preserve, which makes the traditional forest tree grafting method applied to short-branched casuarinas with high cost and low efficiency, especially resulting in waste of materials with target properties
