Embodiment 1

[0013] 1) The North American fir seeds, No. 8871100 provenance, were collected in 1988, produced in Yellow Point, British Columbia, Canada, with longitude 123.5 and latitude 49.03. Sterilize the seeds with 0.3% potassium permanganate solution, soak the seeds at 4°C for 7-14 days, and then store them in sand for 10-20 days, until they are white or the radicle grows more than 1-2mm;

[0014] 2) Select the mixture of sheep manure and peat as the matrix, disinfect it with potassium permanganate solution, disperse and turn it in the sun after a week of stuffiness, then put the matrix into a hexagonal honeycomb container seedbed, and water it thoroughly;

[0015] 3) At the beginning of February of the first year, sow the prepared seed embryo in step 1) on the substrate in the seedbed prepared in step 2), then cover with moss, remove the moss after emergence, and water regularly 1. Fertilization, during which the temperature is maintained at 11-29 ° C, the relative humidity is mainta...

Embodiment 2

[0020] The North American fir seeds, provenance No. 8270002, were collected in 1988 and produced in Vedder Mountain, British Columbia, Canada, at longitude 122 and latitude 49.05. In addition, others are all identical with embodiment 1, when afforestation by the end of September in the second year, the average seedling height of 30 strains of measurement is selected to be up to 22.31cm.

Embodiment 3

[0022] Choose the North American fir seed, 8870059 provenance, gather seed in 1988, produce from Buckley Bay, British Columbia, Canada, longitude 124.45, latitude 49.38, other are all identical with embodiment 1 except that, when afforestation by the end of September in second year , the average seedling height measured by 30 plants was 20.18.

Abstract

The present invention relates to a method for quickly cultivating seedling of fir. Said method includes the following steps: in the course of cultivating seedling making the young seedling undergo the process of light-supplementing treatment by adopting artificial electro optic light source, then making seedling-training treatment outside of greenhouse. Besides, said invention also provides the concrete requirements of the above-mentioned every step.

Description

technical field [0001] The invention relates to a tree seedling raising method, in particular to a fir seedling raising method. Background technique [0002] Abies has been listed as an endangered plant in my country. As a constructive species in high-altitude areas, fir is very important to the restoration of vegetation. Because Abies are generally propagated by seeds, the growth of seedlings and young stands is relatively slow, which severely limits the rapid genetic improvement of Abies. [0003] At present, the existing fir seedling raising method mainly adopts sowing in high beds in the open field, and the purpose is to cultivate seedlings for afforestation. The main technical measures include five aspects: nursery site selection, soil preparation, seed treatment, sowing, and nursery management (including shading, weeding, antifreeze, late frost prevention, pest control, physiological drought prevention and transplantation, etc.). The germination rate of domestic fir ...
