Problems solved by technology

[0003] According to African origin literature 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 described cultivation substrate preferably comprises: after eucalyptus bark, Simao pine bark and oak bark are mixed with mass ratio 6:3:1, carry out decomposing, obtain cultivation substrate. The present invention preferably prepares the cultivation substrate according to the preparation method of the light substrate for organic seedling cultivation using Simao pine bark as raw material disclosed in Chinese patent CN201210498290.8, and replaces Simao pine bark 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 th...

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 order, and the mass percentage content is 0.05% benzalkonium bromide solution for substrate disinfection.

[0033] (3) branch collection and cutting cutting: select the branch that grows robustly, has terminal bud, diameter 0.4cm as cutting; The le...

[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 2cm 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 sequence, and the substrate is sterilized by spraying a 0.075% benzalkonium bromide solution by mass.

[0040](3) branch collection and cutting cuttings: select the branches that grow robustly, have terminal buds, and have a diameter of 0.5 cm as...

Abstract

The invention provides a method for breeding baobabs, which belongs to the technical field of cutting and raising seedlings, and comprises the following steps: 1) sterilizing the cultivation substrate with a benzalkonium bromide solution to obtain a sterilized substrate; 2) treating the baobab cuttings with ampicillin The solution is sterilized to obtain sterilized cuttings, the bottom of the sterilized cuttings is soaked in the fulvic acid solution for 20-40 seconds, and the cuttings are cultivated in the sterilized substrate obtained in step 1). Adopting the breeding method provided by the invention improves the cutting survival rate of the baobab tree.

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 (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 eaten directly 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 eaten after baking. It can also be used to refine edible oil. Its oil content is about 15%, and it is light yellow, which is a high-quality edible oil. Mats and ropes, bark can also be made into red dye. The shell of the fruit can be car...
