Problems solved by technology

[0007] The growth cycle of Taxus Mandia is long. Because the cutting seedlings of Taxus Mandia are affected by diseases such as stem rot, after transplanting in the field, the survival rate of Taxus Mandia is between 75-90%. high cost

Embodiment 1

[0028] The cultivation of cutting seedlings of Taxus chinensis, specifically:

[0029] (1) Nursery construction: use bricks to build a cutting seedbed in the Mandia yew nursery. The cutting seedbed is 1.0-1.5 meters wide, 10-20 meters long, and 10-15 cm high. Leave a 30-50 cm wide trail; the cutting matrix in the cutting bed is formed by mixing perlite and peat soil, the thickness of the cutting matrix is ​​20-25cm, the mass ratio of perlite and peat soil is 2-3:1, and Evenly spray carbendazim solution with a mass percentage concentration of 60-70% on the cutting substrate for disinfection; build plastic sheds and place sunshade nets on the seedbed;

[0030] (2) Cutting and management:

[0031] In spring, collect healthy and plump branches with annual terminal buds on a robust mother tree, and make the branches into cuttings with a length of 10-15cm, and the lower incision of the cuttings is an oblique incision; Soak in ABT1 rooting powder solution for 2-2.5 hours; insert th...

Embodiment 2

[0034] Torreya seedling cultivation, specifically:

[0035] (1) Germination: Torreya seeds are stored in wet sand. During the germination process before sowing, they should be sprinkled and turned frequently to keep the humidity so that the seed coats of the seeds will crack or buds will appear;

[0036] (2) Nursery construction: build a seedbed with bricks in the torreya nursery. The seedbed is 1.0-1.2 meters wide, 10-20 meters long, 10-15 cm high, and 30-50 cm wide between the beds. The footpath; the substrate in the seedbed is river sand, the height is 20-25cm, and the carbendazim solution with a mass percentage concentration of 60-70% is evenly sprayed on the substrate for disinfection; a plastic shed is built on the seedbed and a sunshade net is placed;

[0037] (3) Cultivation and management: Take the seeds that have buds or cracked seed coats and sow them in spring, with a row spacing of 30-40cm and a row spacing of 5-10cm;

[0038] Management: Keep the temperature in ...

Embodiment 3

[0040] The grafting cultivation of Mandia yew, specifically:

[0041](1) Soil preparation and ridging: Sprinkle farmyard manure at an amount of 3000kg / mu on the land to be cultivated, then make the land fluffy, and place a ridge width of 80cm and a height of 15cm on the selected land. Ridge with a width of 25cm; and cover the ridge with plastic film;

[0042] (2) Grafting in spring: collect healthy and full branches with terminal buds on the cutting seedlings of the annual Mandia yew, and make the branches into cuttings with a length of 10-15cm, and the lower incision of the cuttings is an oblique incision; Cut off the upper branches at a distance of 5-8 cm above the ground, dig out the rooted torreya seedlings at the lower part as rootstocks, and make an oblique incision at the top; graft the Mandia yew onto the rootstock, and stick the cutting surface of the scion to the rootstock First, tie it tightly with plastic strips and then smear the mud on the incision to get the gr...

Abstract

The invention provides a taxus media grafting cultivation method. The technical core is that Chinese torreya seedlings of 1-2 years are used as stocks; taxus media of 1-2 years are used as cutting seedlings for carrying out grafting; and a method that cultivating is carried out after grafting is used for grafting cultivation of the taxus media. According to the method provided by the invention, the Chinese torreya seedlings are innovatively adopted as the stocks for grafting the taxus media; the Chinese torreya seedlings are used for overcoming the deficiency of stem rot; a characteristic thatthe disease resistance and the adaptive capacity on a growth environment of Chinese torreya are stronger than the disease resistance and the adaptive capacity of taxus media is utilized, so that theadult rate of the taxus media is improved to 93-97%; and grafting is carried out before cultivation in a field, so that the problem that the labor efficiency is low because grafting is carried out bysquatting in the field after the cutting seedlings survive is avoided.

Description

technical field [0001] The invention belongs to the field of yew cultivation, and in particular relates to a grafting and cultivation method of yew mandia. Background technique [0002] Chinese yew, the paclitaxel content is generally between 0.004%-0.010%, and it is mostly distributed in the bark, so the utilization rate of the whole plant is low when extracting paclitaxel; while the growth rate of Mandia yew is faster than other yew species 3-5 times, the content of paclitaxel is 4-10 times higher than that of Chinese yew varieties, the whole plant of Taxus mandia can be used to extract paclitaxel, and the plant utilization rate is high. Because of the high paclitaxel content and high industrial development value of Taxus Mandia, this project chooses Taxus Mandia as the yew species for the construction of the raw material forest base. Due to the fast growth of Taxus Mandia and the high content of paclitaxel, planting 10,000 mu of Taxus Mandia is at least equivalent to pla...
