Embodiment 1

[0015] (1) In mid-March, 2010, select half-year-old strong seedlings from the seedlings to carry out the cultivation of truncated stems to promote germination, and the height of truncated trunks is 25~30cm, as the mother tree for picking twigs; in mid-May, from Cut semi-lignified twigs with a length of 10 to 15 cm from the fringe-picking mother tree, keep 5 to 6 leaflets in the upper part, and cut the lower ends of the branches into oblique shapes;

[0016] (2) Dissolve rooting powder GGR-6 in water and make it into 800mg / L solution, then pour it into talc powder to make a paste, stick the lower end of the cuttings 2~3cm cut in step (1) A paste made of rooting powder solution and talcum powder;

[0017] (3) The nutrient matrix composition is pine bark: sawdust = 3: 1. After the mixture is fully fermented, it is filled with a non-woven bag with a diameter of 5 cm into long strips, cut into 10-12 cm sections before cutting, and placed in a In a plastic sieve frame with a length...

Embodiment 2

[0021] (1) In the first ten days of April, 2011, select half-year-old strong seedlings from the seedlings to carry out the cultivation of cut stems to promote germination. Cut semi-lignified twigs with a length of 10 to 15 cm from the fringe-picking mother tree, keep 5 to 6 leaflets in the upper part, and cut the lower ends of the branches into oblique shapes;

[0022] (2) Dissolve rooting powder GGR-6 in water and make it into a 1000mg / L solution, then pour it into talc powder to make a paste, stick the lower end of the cuttings 2 to 3 cm cut in step (1) A paste made of rooting powder solution and talcum powder;

[0023] (3) The nutrient matrix composition is pine bark: sawdust = 3: 1. After the mixture is fully fermented, it is filled with a non-woven bag with a diameter of 5 cm into long strips, cut into 10-12 cm sections before cutting, and placed in a In a plastic sieve frame with a length of 50 cm x a width of 50 cm x a depth of 10 cm, pour it thoroughly with 0.5% potas...

Abstract

The invention discloses a softwood cuttage propagation method for Acrocarpus fraxinifolius according to the principle of vegetative propagation. Fine clone seedlings can be propagated in quantity by the softwood cuttage propagation technique for Acrocarpus fraxinifolius, and accordingly high yield and high quality of colonies can be realized. The softwood cuttage propagation method for Acrocarpus fraxinifolius is characterized in that rooting agent GGR-6 is provided by Beijing ABT research and development center, the rooting agent GGR-6 is made into 800-1000mg/L solution at constant volume, talcum powder is added into a container in multiple phases during mixing until the solution is pasty, the lower ends of semi-lignified shoots 10-15cm long are dipped into the paste and inserted into a nonwoven nutrition bag having 5cm diameter and nutrition substance composed of pine bark and sawdust in a ratio of 3:1, water-fertilizer management and disease damage control are performed as required after cuttage, and the shoots grow and survive in two months.

Description

technical field [0001] The invention relates to a method for cutting and propagating twigs of acrocarp tree, belonging to the technical field of plant vegetative propagation. Background technique [0002] Apical fruit tree is a tall tree of Hematoxylinaceae. It is not only a precious native timber tree species, but also an excellent stone mountain afforestation tree species. Existing natural resources are scarce, and it has been listed as a third-level protected plant in my country. At present, seeds are mainly used for sowing and raising seedlings in production. Due to the diversity of genetic materials, seedlings have different growth phenotypes after afforestation, and it is difficult to achieve high-yield and high-quality populations. Plant vegetative propagation technology has been widely used in forest tree cuttings and seedlings. A large number of excellent clonal seedlings can be propagated by using the cutting propagation technology of apex fruit trees, so as to ach...
