Problems solved by technology

Although the improved variable temperature stratification treatment can further shorten the dormant period of seeds, it is easy for bacteria to breed during the warm temperature treatment, causing the seeds to rot before germination

Embodiment 1

[0038] This embodiment is carried out in the Songlinpo area of ​​Jianshan Mountain in Shangzhai, Luzhang Town, Lushui County, Nujiang Prefecture.

[0039]In mid-to-late October, collect mature yew fruits, mix and rub the seeds with coarse sand to thin the seed coat, and rinse them clean. Then mix the seeds with wet river sand in a ratio of 1:2 and store them in an earth pit. The earth pit is selected in a shady, dry, and water-free place, and the size of the pit cavity is proportional to the amount of seeds. The seeds were taken out in February of the following year, soaked in a mixture of 55°C white wine and 50°C warm water with a volume ratio of 1:1 for 20 minutes, then soaked in 0.4% gibberellin solution for 20 hours, and moved to a 20°C greenhouse for germination at the end of March. Sow when the seeds are white. Deeply plow the land, select seedbeds, apply fermented farmyard manure 375t / mu, and make furrows, with two furrows along the length and slightly lower in the mid...

Embodiment 2

[0041] This embodiment is carried out in the Songlinpo area of ​​Jianshan Mountain in Shangzhai, Luzhang Town, Lushui County, Nujiang Prefecture.

[0042] In mid-to-late October, collect mature yew fruits, rub the seeds repeatedly on the rough concrete floor to thin the seed coat, and rinse them clean. Then mix the seeds with wet river sand at a ratio of 1:3.5 and store them in an earth pit. The earth pit should be in a shady, dry place without water accumulation, and the size of the pit cavity is proportional to the amount of seeds planted. The seeds were taken out in February of the following year, soaked in 0.15% mercuric chloride solution for 10 minutes, then soaked in 0.2% Fengxianbao for 22 hours to accelerate germination, and moved to a 20°C greenhouse for acceleration in March, and the seeds can be sown when the seeds are white. The land is plowed deeply, the seedbed is selected, and 480t / mu of fermented farmyard manure is applied to make a furrow. The two furrows are ...

Embodiment 3

[0044] This embodiment is carried out in the Songlinpo area of ​​Jianshan Mountain in Shangzhai, Luzhang Town, Lushui County, Nujiang Prefecture.

[0045] In late September, collect mature yew fruits, mix and rub the seeds with coarse sand to thin the seed coat, and rinse them clean. Then mix the seeds with wet river sand in a ratio of 1:5 and store them in an earth pit. The earth pit is selected in a shady, dry, and water-free place, and the size of the pit cavity is proportional to the amount of seeds. In March of the following year, the seeds were taken out, soaked in 0.15% potassium permanganate solution for 15 minutes, and then soaked in 0.5% gibberellin solution for 24 hours to germinate. In April, they were moved to a greenhouse at 25°C for germination, and they could be sown when the seeds were white. The land is plowed deeply, the seedbed is selected, and 600t / mu of fermented farmyard manure is applied to make a furrow. The two furrows are along the length and slightl...

Abstract

The invention discloses a seedling culturing method for a Chinese yew. The seedling culturing method includes the steps of seed collection, seed storage, seed processing, soil preparation and seedling, seedling management, transplantation, interplanting and the like. Firstly, seed coats of seeds are thinned through a rubbing method, then the seeds are mixed with wet sand and stored in a soil pit, in the next spring, the seeds are taken out and sequentially soaked in disinfectant and plant growth regulator, then, the seeds undergo accelerating germination in a greenhouse, and the seeds can be planted when the seeds become white. Farmyard manure is added after deep ploughing and soil preparation, the seeds are planted on a seedbed, covered by thin soil, watered and receive moisturizing processing, and 50-70% of the seeds are shaded in a seedling stage. In the process of transplantation, neutral and acidulous properly-thick soil layers with the height of 1500-3500m are selected, base fertilizer is added, roots of sprouts are soaked in wet earth containing organic fertilizer, and then the sprouts are planted in a three-dimensional growth environment in an interplanting mode, wherein the tree of overstory in the three-dimensional growth environment is pinus yunnanensis, and ground flora of the three-dimensional growth environment is fern. Tests show that according to the seedling culturing method for the Chinese yew, dormancy periods of Chinese yew seeds can be shortened greatly, bud ratios and transplantation survival rates are improved, and the Chinese yew is quick in growth, early in fruiting and suitable for being popularized and planted in a large area.

Description

technical field [0001] The invention belongs to the technical field of tree cultivation, and in particular relates to a yew seedling raising method which can greatly shorten the dormancy period of seeds and improve the germination rate and transplanting survival rate. Background technique [0002] The species of the genus Taxus in the family Taxaceae are large evergreen trees, and five of them are national first-class key protected plants. The active substance has high medicinal development value. However, the development of the anticancer drug paclitaxel has led to the predatory destruction of the natural resources of this plant. In order to protect the precious species resources of Taxus and ensure the sufficient, stable and balanced supply of Taxol, Taxus should be actively cultivated Plantation resources. [0003] It is an effective way to alleviate the shortage of paclitaxel supply and the serious shortage of precious timber forest resources by using seeds to propagat...
