Embodiment 1

[0019] The seedling raising and grafting method of metasequoia aureus, comprises the following steps:

[0020] 1. Prepare the nutrient solution: the components are calculated by weight percentage, including 3% auxin, 2% sucrose, 1% acetylacetone, and 2% α-methyl tert-butyl methyl ether, mixed and prepared for later use;

[0021] 2. Prepare the scion: choose Metasequoia aureus with a length of 4cm as the scion, soak it in the nutrient solution of step 1 for 0.5h, take it out and filter it;

[0022] 3. Prepare the rootstock: select the metasequoia with a trunk diameter of 2 cm as the stock, cut off the part of the trunk that is more than 8 cm from the root, flatten the fracture, and then cut obliquely from the top of the stock to the range of 3 cm from the top to form the grafting surface of the stock;

[0023] 4. Grafting operation: During November to December, graft the scion on the rootstock grafting surface, use gauze to soak the nutrient solution in step 1, wrap it at the g...

Embodiment 2

[0026] The seedling raising and grafting method of metasequoia aureus, comprises the following steps:

[0027] 1. Prepare the nutrient solution: the components are calculated by weight percentage, including 1% auxin, 3% sucrose, 0.5% acetylacetone, and 2% α-methyl tert-butyl methyl ether, mixed and prepared for later use;

[0028] 2. Prepare the scion: choose Metasequoia aureus with a length of 4cm as the scion, soak it in the nutrient solution of step 1 for 0.5h, take it out and filter it;

[0029] 3. Prepare the rootstock: select the metasequoia with a trunk diameter of 3 cm as the stock, cut off the part above the root 8 cm on the trunk, flatten the fracture, and then cut obliquely from the top of the stock to the range of 3 cm from the top to form the grafting surface of the stock;

[0030] 4. Grafting operation: During November to December, graft the scion on the rootstock grafting surface, use gauze to soak the nutrient solution in step 1, wrap it at the grafting interfa...

Embodiment 3

[0033] The seedling raising and grafting method of metasequoia aureus, comprises the following steps:

[0034] 1. Prepare the nutrient solution: the components are calculated by weight percentage, including 2% auxin, 1% sucrose, 1.5% acetylacetone, and 1.5% α-methyl tert-butyl methyl ether, mixed and prepared for later use;

[0035] 2. Prepare the scion: choose Metasequoia aureus with a length of 3cm as the scion, soak it in the nutrient solution in step 1 for 0.5h, take it out and filter it;

[0036] 3. Prepare the rootstock: select the metasequoia with a trunk diameter of 3 cm as the stock, cut off the part of the trunk that is more than 8 cm from the root, flatten the fracture, and then cut obliquely from the top of the stock to the range of 2 cm from the top to form the grafting surface of the stock;

[0037] 4. Grafting operation: During November to December, graft the scion on the rootstock grafting surface, use gauze to soak the nutrient solution in step 1, wrap it at t...

Abstract

The invention discloses a method for seedling and grafting metasequoia glyptostroboides GoldRush in the technical field of forestry plant culture. The method comprises the following steps: preparing a nutrient solution which is prepared from the following components in percentage by weight: 1-3 percent of plant hormone, 1-3 percent of cane sugar, 0.5-1.5 percent of acetylacetone and 1.5-2 percent of alpha-methyl tert-butyl ether, mixing for later use; preparing scion and stock; grafting the scion on the grafting surface of the stock from November to December, coating the grafting position with gauze soaked with the nutrient solution, and binding with a belt; and covering the stock and scion with a mulching film after grafting is completed, and tearing an opening in the mulching film corresponding to a bud when the bud grows for 3-4cm to facilitate growth of the bud. The method has the beneficial effects of maintaining the physiological activities of the stock and scion, promoting formation of a dredging tissue and benefiting nutrition and moisture transmission, and overcomes the technical problem in the prior art that the grafting opening cannot be easily healed and the scion grows slowly since the stock does not supply sufficient moisture and nutrition to the scion.

Description

technical field [0001] The invention relates to the technical field of forestry plant cultivation, in particular to a method for seedling raising and grafting of metasequoia aureus. Background technique [0002] Grafting is a method of vegetative reproduction in asexual reproduction, including root grafting, branch grafting and bud grafting. Grafting is carried out by utilizing the ability of plants to heal after injury. During grafting, the cambiums of the two injured surfaces are brought close together and tightly bound together, through the proliferation of cells, they heal each other and become vascular tissues to connect together to form a whole. [0003] Plant grafting is the use of wounded plants, which can form calluses around the wound and have the characteristics of regeneration ability. The size of this regeneration ability is closely related to the affinity of root scion and rootstock and the healing effect of cambium. Consider factors such as selection and han...
