Problems solved by technology

[0003] According to African origin document reports (SCUC. Baobab Manual, Field Manual for Extension Workers and Farmers [M], Southampton: University of Southampton, 2006.), baobab branches are soaked in IBA solution, and the survival rate of cuttings is 20%. , but the survival rate of cutting seedlings without hormone soaking treatment is only 2%

preparation example Construction

[0023] In the present invention, the preparation method of the cultivation substrate preferably comprises: mixing eucalyptus bark, simao pine bark and oak bark at a mass ratio of 6:3:1 and then decomposing to obtain the cultivation substrate. In the present invention, the cultivation substrate is preferably prepared according to the preparation method of organic seedling-growing light substrate with Simao pine bark as raw material disclosed in Chinese patent CN201210498290.8, and the Simao pine bark is replaced with eucalyptus bark, Simao pine bark and oak bark. In the present invention, the cultivation mechanism is breathable and does not accumulate water, which is easy for the root system of the baobab to grow, thereby improving the survival rate of the baobab.

[0024] In the present invention, the mass percent content of the benzalkonium bromide solution is preferably 0.05-0.1%. The present invention preferably adopts the conventional spraying method to sterilize the culti...

Embodiment 1

[0031] (1) Seedbed selection and treatment: After removing weeds and leveling the seedbed, lay a layer of sand or gravel on the ground so that the bottom of the seedbed is 3cm above the ground, and surround the seedbed with red bricks.

[0032] (2) Nutrient bag preparation and disinfection: the bark raw material seedling-raising substrate (the raw material of seedling-raising substrate is eucalyptus bark, Simao pine bark and oak bark that mass ratio is 6:3:1, according to Chinese patent CN201210498290. Simao pine bark is the preparation method of the organic seedling-raising light matrix of raw material (preparation) filling into diameter 6cm, in the nutrition bag of high 12cm. The filled nutrition bags are placed in the seedbed in sequence, and the substrate is sterilized by spraying a 0.05% benzalkonium bromide solution by mass.

[0033] (3) Branch collection and cutting cuttings: select robust growth, branches with terminal buds and 0.4 cm in diameter as cuttings; after cut...

[0038] (1) Seedbed selection and treatment: After removing weeds and leveling the seedbed, lay a layer of sand or gravel on the ground so that the bottom of the seedbed is 2 cm above the ground, and surround the seedbed with red bricks.

[0039] (2) Nutrient bag preparation and disinfection: the bark raw material seedling-raising substrate (the raw material of seedling-raising substrate is eucalyptus bark, Simao pine bark and oak bark that mass ratio is 6:3:1, according to Chinese patent CN201210498290. Simao pine bark is the preparation method of the organic seedling-raising light matrix of raw material (preparation) filling into the diameter 5cm, in the nutrient bag of high 10cm. The filled nutrition bags are placed in the seedbed in order, and the substrate is sterilized by spraying a 0.075% benzalkonium bromide solution by mass.

Abstract

The invention provides a breeding method for baobab and belongs to the technical field of cutting seedling raising. The breeding method comprises the following steps of (1) disinfecting a culture substrate with a benzalkonium bromide solution to obtain a disinfected substrate; and (2) disinfecting baobab cuttings with an ampicillin solution to obtain disinfected cuttings, soaking the bottom ends of the disinfected cuttings into a fulvic acid solution for 20-40 seconds and putting the cuttings into the disinfected substrate obtained in the step (1) for cultivation. By adopting the breeding method provided by the invention, the cutting survival rate of the baobab is improved.

Description

technical field [0001] The invention belongs to the technical field of seedling raising by cuttings, and in particular relates to a breeding method of baobabs. Background technique [0002] Baobab (Adansonia digitata) is a large perennial deciduous tree belonging to the family Bombacaceae, native to tropical arid regions of Africa. Baobab is a tree species with high economic value and is widely used. Its dry leaves are rich in carotene and vitamin A, and the protein content of young leaves is 4%. The leaves can also be used as seasoning; the fruit pulp is juicy and can be directly eaten as fruit or brewed into fruit wine drinks; the seeds can be eaten raw as snacks, It can also be used as a thickener, flavoring agent and edible after baking. It can also be used to refine edible oil. Its oil content is about 15%, which is light yellow and is a high-quality edible oil. Mats and ropes, bark can also be made into red dye. The shell of the fruit can be carved into various ladl...
