specific Embodiment 1

[0037] figure 1 , figure 2 , image 3 , Figure 4 and 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 of interface

[0040] refer to figure 1 , Select the branches with good growth and full buds in the upper part of the crown of the female parent of Dalbergia japonica. After the branch scion is removed, cut off the leaves in time, remove the useless parts, and carefully wrap it with a wet towel or straw paper to keep moisture. The bud strip is segmented with branch shears during grafting, and a segment of double buds or single buds, each segment becomes a scion;

[0041] refer to figure 2 and image 3 , use a blade to trim the long petiole of the scion, and then cut out an oblique opening of 30-45 inclination at the lower part of the bud eye, the length of the oblique opening is 0.6cm-0.8cm, and then reverse the oblique knife o...

specific Embodiment 2

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

[0055] The rest are the same as in 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 matrix seedling with good vigor, and the light matrix seedling is the seedling cultivated using the light matrix, wherein the light matrix can be used 50% loam, 50% peat (or vermiculite, perlite and other light materials) Minerals, coniferous bark powder, coconut bran, plant fiber and other agricultural and forestry wastes), fumigated and sterilized by formalin solution for 20 to 30 days, mixed and mixed well, then installed in a tube, and added 0.1% one day before transplanting seedlings Potassium permanganate solution for disinfection. It can be flexibly selected according to the actual situation in various places, and it is not particularly fixed.

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

[0060] The rest are the same as the ...

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 grafting technology of Dalbergia Dalbergia, in particular to a "mutual"-shaped grafting and a later management method of Dalbergia Dalbergia. It belongs to the field of seedling breeding. Background technique [0002] Dalbergia odorifera T.Chen, also known as Hainan huanghuali, is a semi-deciduous tree of the genus Dalbergia of the butterfly family Dalbergia. One of them is a national second-class protected tree species, native to Hainan Island. In recent years, driven by economic interests, the phenomenon of Dalbergia japonica being stolen and felled is very serious. The preserved high-quality resources are extremely scarce, which makes it valuable. 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 tree species for planting. However, at present, Dalbergia Dalbergia is mainly propagated b...
