Problems solved by technology

[0003] At present, the development of teak commercial forests in my country is mainly based on seed seedlings and tissue cultured invisible line seedlings. Tissue culture is difficult to promote in actual production because of its high cost and high technical requirements, and seed seedlings are often used as Nutrient bag seedlings with yellow core soil as the substrate rely on manual bagging, which is labor-intensive and has low yield. Teak can also be cultivated by cuttings, but the seedlings cultivated by cuttings have poor root growth potential, low survival rate, and poor cold resistance of seedlings. Growth is weak

Embodiment 1

[0043] like Figure 1-Figure 2 Shown, a kind of cultivation method of teak seedling, comprises the following steps:

[0044] A. Mother plant cultivation

[0045] Seeds are sown on sand beds in mid-April, and when the seedlings grow to a height of 8-9cm, they are transplanted into a mother plant container cup equipped with a nutrient substrate, drenched with root water, and set up a three-layer sunshade net. The net includes the first layer of sunshade net, the second layer of sunshade net and the third layer of sunshade net with light transmittance of 80%, 60% and 40% from bottom to top. The distance between two adjacent layers of sunshade nets is 20- 25cm, on the 12th day after the mother plant was transplanted, remove the third layer of sunshade net, 18 days after transplanting, remove the second layer of sunshade net, remove the first layer of sunshade net in cloudy days, and build the first layer of sunshade net in sunny days. It is 0.2% compound fertilizer aqueous solut...

Embodiment 2

[0064] like Figure 1-Figure 2 Shown, a kind of cultivation method of teak seedling, comprises the following steps:

[0065] A. Mother plant cultivation

[0066] Sow seeds on the sand bed in mid-April. When the seedlings grow to a height of 9cm, they are transplanted in the mother plant container cup equipped with a nutrient substrate, drenched with root water, and set up a three-layer sunshade net. The three-layer sunshade net includes The first layer of sunshade nets, the second layer of sunshade nets and the third layer of sunshade nets with light transmittances of 80%, 60% and 40% from bottom to top. The distance between two adjacent layers of sunshade nets is 23cm. On the 13th day after transplanting, remove the third layer of sunshade net, 19 days after transplanting, remove the second layer of sunshade net, remove the first layer of sunshade net on cloudy days, and build the first layer of sunshade net on sunny days, every 11 days Drench once mass fraction is 0.25% co...

Embodiment 3

[0085] like Figure 1-Figure 2 Shown, a kind of cultivation method of teak seedling, comprises the following steps:

[0086] A. Mother plant cultivation

[0087] Sow seeds on the sand bed in mid-April. When the seedlings grow to a height of 9cm, they are transplanted in the mother plant container cup equipped with a nutrient substrate, drenched with root water, and set up a three-layer sunshade net. The three-layer sunshade net includes The first layer of sunshade nets, the second layer of sunshade nets and the third layer of sunshade nets with light transmittances of 80%, 60% and 40% from bottom to top. The distance between two adjacent layers of sunshade nets is 25cm. On the 13th day after transplanting, remove the third layer of sunshade net, 20 days after transplanting, remove the second layer of sunshade net, remove the first layer of sunshade net on cloudy days, and build the first layer of sunshade net on sunny days, every 12 days Drench once mass fraction is 0.3% com...

Abstract

The invention discloses a method for cultivating a teak seedling. Grafting comprises the following steps: (1), cutting wood collection: selecting a lateral branch with the diameter of 3-5 cm and the length of 5-7 cm and close to one end of a main branch on a stock plant in mid April of next year, taking the lateral branch as a cutting wood, cutting the base of the cutting wood to form a bulge of which the exterior is cylindrical, wherein the internal diameter of the bulge is gradually reduced from the lower end to the upper end of the base of the cutting wood so as to form an internal space in a circular truncated cone shape; (2), stock processing: selecting an excellent root segment of a lobular red sandalwood tree as a stock with the length of 8-10 cm, wherein a notch is a groove which contains the bulge and is matched with the bulge; (3), cottage grafting: coating sticky liquid in the groove of the stock, inserting the bulge of the cutting wood into the groove of the stock, coating the sticky liquid on the connection part, winding to cover the connection part from bottom to top by utilizing a plastic film, binding tightly and ensuring the sealing. According to the method for cultivating the teak seedling, the root segment of the lobular red sandalwood tree is taken as the stock to graft and cultivate the teak seedling, so that the teak seedling with high root growth vigor and high survival rate can be obtained.

Description

technical field [0001] The invention relates to a method for cultivating precious tree seedlings. More specifically, the present invention relates to a method for cultivating teak seedlings. Background technique [0002] Teak belongs to Verbenaceae Teak is a large semi-deciduous tree. The heartwood of teak has a large proportion and is dark brown. It is extremely resistant to insects, decay, water, and fire. , has a wide range of uses, and is recognized as one of the high-quality and precious woods in the world. It has large planting areas in Hainan, Yunnan, Guangxi and other places in my country. [0003] At present, the development of teak commercial forests in my country is mainly based on seed seedlings and tissue cultured invisible line seedlings. Tissue culture is difficult to promote in actual production because of its high cost and high technical requirements, and seed seedlings are often used as Nutrient bag seedlings with yellow core soil as the substrate rely on m...
