Embodiment 1

[0035] The slope cutting operation is carried out in the greenhouse in late September:

[0036] (1) Preparation of panicle seedlings: collect the seeds of healthy and straight-trunked wild sloping trees (diameter at breast height 42.5cm, tree height 16.5m) for seedling cultivation; then select excellent seedlings (ground diameter ≥ 0.6cm, seedling height ≥60cm) to build an ear-picking nursery; when the seedlings grow to the second year, select semi-lignified twigs with a lower diameter of 0.22 cm from the seedlings in the ear-picking garden as cutting materials;

[0037] (2) Preparation of mixed substrate and container selection: Mix peat soil, vermiculite, perlite, and coconut peat in a volume ratio of 5:2:2:1 to obtain a mixed substrate; then put the mixed substrate into a cutting container, 2 days before the cutting, use a potassium permanganate solution with a mass percentage of 0.3% to spray and disinfect the substrate. The mixed substrate shall prevail. The cutting conta...

Embodiment 2

[0042] The slope cutting operation is carried out in the greenhouse in late April:

[0043] (1) Preparation of panicle seedlings: collect the seeds of healthy and straight-trunked wild sloping trees (diameter at breast height 38.0cm, tree height 16.8m), carry out seed breeding, and then select excellent seedlings (ground diameter ≥ 0.6cm, seedling height ≥60cm) to build an ear-picking garden; when the seedlings grow to the second year, select semi-lignified shoots with a lower diameter of 0.30 cm from the seedlings in the ear-picking garden as cutting materials;

[0044] (2) Preparation of mixed substrate and container selection: Mix peat soil, vermiculite, perlite, and coconut peat in a volume ratio of 5:2:1:1 to obtain a mixed substrate; then put the mixed substrate into the cutting container, 2 days before the cutting, use a potassium permanganate solution with a mass percentage of 0.3% to spray and disinfect the substrate, subject to the mixed substrate being drenched, and...

Embodiment 3

[0049] The slope cutting operation is carried out in the greenhouse in late April:

[0050] (1) Preparation of panicle seedlings: collect the seeds of healthy and straight-trunked wild sloping trees (diameter at breast height 35cm, tree height 16.5m) for seedling cultivation, and then select excellent seedlings (ground diameter ≥ 0.6cm, seedling height ≥ 60cm) to build an ear-picking nursery; when the seedlings grow to the second year, select semi-lignified twigs with a lower end diameter of 0.26cm as cuttings from the seedlings in the ear-picking garden;

[0051] (2) Preparation of mixed substrate and container selection: Mix peat soil, vermiculite, perlite, and coconut peat in a volume ratio of 5:2:2:1 to obtain a mixed substrate; then put the mixed substrate into a cutting container, 2 days before the cutting, use a potassium permanganate solution with a mass percentage of 0.3% to spray and disinfect the substrate. The mixed substrate shall prevail. The cutting container sh...

Abstract

The invention discloses a hopea hainanensis semi-lignification tender branch cutting seedling raising method. The method includes: collecting the seeds of hopea hainanensis select trees for seedling raising, and selecting good seedlings to build a cutting orchard; in the second growing year of the seedlings in the cutting orchard, selecting the special part of a semi-lignification tender branch as a cutting material, shearing the same into 10-15cm in length, and retaining 1 / 3 of each of two leaves close to the top; allowing the upper cut of the cutting material to be flat and lower cut to be oblique and close to a leaf joint; immediately cleaning the sterilizing the taken and processed cutting material, soaking the lower portion of the cutting material into prepared plant growth adjusting agent for a certain time, performing cutting material cuttage on a matrix, and performing post management after the cuttage to obtain robust hopea hainanensis seedlings. By the method, hopea hainanensis cuttage rooting percentage and survival rate are increased, the rooting process is shortened effectively, fast reproduction is achieved, good inheritable characters of the select trees can be kept, and the method is low in cost, easy to popularize and promising in development prospect.

Description

technical field [0001] The invention belongs to the technical field of plant vegetative propagation, and in particular relates to a method for growing seedlings by cutting semi-lignified twigs on slope bases. Background technique [0002] Hopea hainanensis Merr.et Chun, also known as Hainan Kebimu, Haimei, Shizigong, and Wannianmu, is an evergreen tree species of the genus Hopea in the family Dipterocarpaceae. Polei is a precious timber in my country and one of the five special types of wood species in Hainan (polei, pear, Zijing, mother and litchi). The wood structure is uniform, dense, interlaced, oily and beautiful, tough and durable. It is not infested by moths, and it is still immortal after being buried in the ground for 40 years. Its material is the crown of Hainan tree species, and it is most suitable for special industries, crafts, high-end furniture and interior decoration. In addition, the light yellow resin can be used as raw materials for medicine and paint. [...
