specific Embodiment 1

[0037] figure 1 , figure 2 , image 3 , Figure 4 with Figure 5 Constitute the specific embodiment 1 of the present invention.

[0038] The grafting method of the present embodiment is as follows:

[0039] 1) Collection of scion and formation interface

[0040] refer to figure 1 , Select well-growing branches with full buds in the middle and upper part of the female parent's crown of Dalbergia japonica, cut off the leaves in time after the scion is removed, remove useless parts, and wrap carefully with a wet towel or straw paper to moisturize. When grafting, use branch scissors to divide the bud bar into sections, double buds or single buds, and each section becomes a scion;

[0041] refer to figure 2 with image 3 , use a blade to trim the scion off the overly long petiole, and then cut out a 30-45 inclination at the lower part of the bud eye. Slightly, a small back-slope is formed, and then the 1.6cm-2.0cm-long epidermis is split straight along the back-slope ax...

specific Embodiment 2

[0054] refer to Image 6 , in the " mutual " shape grafting of the 3rd) step, the oblique mouth of scion is aligned with the oblique opening of rootstock, make them fit closely, form " mutual " type.

[0055] All the other are with specific embodiment 1.

specific Embodiment

[0057] The main features of other specific embodiments of the present invention are: in each step:

[0058] The 2nd) step can adopt the light substrate seedling with good vigor, and described light substrate seedling is the nursery stock that uses light substrate to cultivate, and wherein light substrate can use 50% loam, 50% peat (or light substrate such as vermiculite, perlite) minerals, coniferous bark powder, coir peat, plant fiber and other agricultural and forestry wastes), fumigated and sterilized with formalin solution for 20 to 30 days, mixed well and filled into tubes, and then used 0.1% Potassium permanganate solution for disinfection. It can be flexibly selected according to the actual situation in each place, and it is not particularly fixed.

[0059] 2) In step selection stock, seedling height can be 60cm, 70cm or 80cm, and ground diameter can be 0.6cm, 0.7cm or 0.8cm.

[0060] All the other are with specific embodiment 1 and specific embodiment 2.

Abstract

The invention discloses Chinese character hu-shaped grafting and final-period management methods for Dalbergia odorifera. The grafting method comprises the following steps of: 1) collecting cions, namely selecting and taking branch cions growing well on the top and middle part at the periphery of the crown of a Dalbergia odorifera female parent, cutting out leaves timely, removing useless parts, carefully wrapping with a wet towel or coarse paper and moisturizing; 2) selecting stocks, namely selecting Dalbergia odorifera container seedling which has height of between 50 and 80 cm, the ground diameter of between 0.5 and 0.8 cm and grows well; 3) treating ports, namely chopping cions and stocks by using a sharp grafting tool; and 4) performing Chinese character hu-shaped grafting, namely aligning the cion with a treated port with stock cambium to ensure that the cion with the treated port is tightly adhered to the stock cambium to form a shape like a Chinese character 'hu', so the largest area of the cambium connecting the cion is ensured. The final-period management method comprises the following steps of: 1) performing water and fertilization management; 2) removing sprouts timely; and 3) removing shoot at proper time. The methods effectively solve the problem of low survival rate of the conventional grafting technology and have great market competitive force, so that the methods have wide application prospect and can produce great economic benefit.

Description

technical field [0001] The invention relates to a technique for grafting Dalbergia balsamicus, in particular to a method for "mutually" grafting and post-management of Dalbergia balsamicus. It belongs to the field of nursery stock breeding. Background technique [0002] Dalbergia odorifera T.Chen, also known as Hainan huanghuali, is a semi-deciduous tree belonging to the Papilionaceae Dalbergia genus. One of them is a national second-class protected tree species, native to Hainan Island. In recent years, driven by economic interests, Dalbergia japonica has been stolen and felled very seriously, and the preserved high-quality resources are extremely scarce, making it of great value. At the same time, it has created a high enthusiasm for forest farmers in South China to plant precious tree species. Dalbergia has undoubtedly become one of the most popular and precious planted trees. However, at present, Dalbergia Dalbergia is mainly propagated by seeds. Because it is a cross...
