Embodiment 1

[0034]Choose a plot with sufficient sunlight, no water accumulation, and nearby water sources as the ear picking nursery, dig drainage ditches around the nursery, and build a kui surface with a width of 1.0 m and a height of 5-10 cm. The distance between kui and kui is 40 cm; in February, high-quality tissue-cultured seedlings of Chinese fir were selected as the mother plant for ear picking, and the trunk of the mother plant was planted at an angle of 65-70 degrees to the ground toward the center of the Kui surface. Before planting, 40-50 g of compound fertilizer was applied to each plant as a base fertilizer. The row spacing of the mother plant is 60 cm, and the plant spacing is 40 cm. After the mother plant is planted, the fungicide is sprayed every 20-30 days, and the carbendazim, thiophanate-methyl, dexazone, mancozeb, and Use fungicides such as bacteria clear in turn; use compound fertilizer to fertilize the mother plant every month, spread dry fertilizer before or before ...

Embodiment 2

[0036] Choose a plot with sufficient sunlight, no water accumulation, and nearby water sources as the ear-picking nursery, dig drainage ditches around the nursery, and build a Kui surface with a width of 1.2 m and a height of 5-10 cm. The distance between Kui and Kui is 60 cm; in February, high-quality tissue culture seedlings of Chinese fir were selected as the mother plant for ear picking, and the trunk of the mother plant formed an angle of 60-65 degrees with the ground and planted obliquely toward the center of the Kui surface. Before planting, 40-50 g of compound fertilizer was applied to each plant as a base fertilizer. The row spacing of the mother plant is 60 cm, and the plant spacing is 40 cm. After the mother plant is planted, the fungicide is sprayed every 20-30 days, and the carbendazim, thiophanate-methyl, dexazone, mancozeb, and Use fungicides such as bacteria clear in turn; use compound fertilizer to fertilize the mother plant every month, spread dry fertilizer b...

Embodiment 3

[0038] Choose a plot with sufficient sunlight, no water accumulation, and nearby water sources as the ear-picking nursery, dig drainage ditches around the nursery, and build a Kui surface with a width of 1.2 m and a height of 5-10 cm. The distance between Kui and Kui is 60 cm; in February, high-quality tissue-cultured seedlings of Chinese fir were selected as the mother plant for ear picking, and the trunk of the mother plant was planted at an angle of 65-70 degrees to the ground toward the center of the Kui surface. Before planting, 40-50 g of compound fertilizer was applied to each plant as a base fertilizer. The row spacing of the mother plant is 80 cm, and the plant spacing is 30 cm. After the mother plant is planted, the fungicide is sprayed every 20-30 days, and the carbendazim, thiophanate-methyl, dexazone, mancozeb, and Use fungicides such as bacteria clear in turn; use compound fertilizer to fertilize the mother plant every month, spread dry fertilizer before or before...

Abstract

The invention discloses a seedling-to-seedling method using tissue culture seedlings of cunninghamia lanceolata. The method has the advantages that a standard cutting orchard is built, two rows of stock plants are arranged symmetrically and are planted and cultivated by enabling trunks to obliquely incline to the center of the ridge surface to form angles of 60-75 degrees with the ground, the stock plants are layered towards the center of the ridge surface by hooking portions, 30-50cm in height, of the stock plants by steel hooks after 7-8 months of stable growth of the stock plants, and angles of 33-50 degrees are formed between the trunks of the stock plants and the ground, so that damage to the stock plants is avoided, the stock plants do not affect one another, illumination is reasonable, and management is facilitated; hormones are sprayed to the roots of the stock plants to promote germination, so that substantial high-quality coppice shoots uniform in specification can be obtained to serve as cutting slips, orderly cutting nursery stocks can be cultivated, and propagation coefficients of the nursery stocks are increased effectively; special seedling cultivation equipment is not needed, simplicity and easiness in operation are achieved, technical requirements are low, and seedling cultivation cost and time are greatly saved; seedling cultivation is performed by vegetative propagation of cuttings, so that excellent inheritable characters of excellent varieties of the cunninghamia lanceolata are kept well, and high economic, social and ecological benefits are achieved.

Description

Technical field: [0001] The invention belongs to the technical field of plant asexual reproduction, and relates to a method for multiplying seedlings by adopting Chinese fir tissue culture seedlings. Background technique: [0002] Chinese fir( Cunninghamia lanceolata ) belongs to the genus Chinese fir, is one of the unique evergreen coniferous timber tree species in my country, and is also one of the main afforestation tree species in southern my country. Chinese fir has a history of more than one thousand years of cultivation and plays an important role in the development of forestry. It can be called the "king of trees" in southern China. Chinese fir grows fast, has high yield, and is widely distributed. Its wood material is light and tough, uniform in structure, straight in texture, and easy to process. It is not only a good furniture material and building material, but also an excellent pulp material. It is loved by the masses. Chinese fir is the main tree species f...
