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
The present invention relates to the seedling-cultivating method of a kind of trees, particularly the seedling-cultivating method of fir.
Background technology
Fir has been put into endangered plants in China, and as the constructive species of high altitude localities, fir is extremely important to the recovery of vegetation.Because fir generally is by seminal propagation, seedling and young growth phase growth fraction are slower, have therefore seriously limited the quick genetic improvement of fir.
At present, existing fir seedling-cultivating method mainly adopts the high bed of open country to broadcast sowing, and purpose is to cultivate nursery stock afforestation.Wherein the major technique measure comprise that nursery lot is selected, the technology of five aspects in whole ground, seed treatment, sowing, nursery bed management (comprise shade, weeding, antifreeze, anti-late frost, diseases prevention worm, prevent physiological drought and transplanting etc.).Domestic abies seeds germination rate is very low, be generally 10-25%, through outdoor sowing, survive the winter, the harm of sick worm, living time-division bed transplanting in 2 years etc., depositing the seedling rate when causing the garden does not only wait for 30%-70%, 3 years living Abies recurvata heights of seedling are 6.72cm (referring to " Gansu forestry science and technology " 1998.04.17-20) only, and just can go out garden (referring to " forestry science and technology communication " 2000.11:37-38) during height of seedling 25cm, and as seen need cultivate 4-5 at least, just have the part nursery stock and reach the garden requirement.Existing fir seedling-cultivating method program is too loaded down with trivial details, and natural environmental condition is uncontrollable, and has a lot of natural conditions that there is threat in the survival of fir seedling; And growing-seedling period is long, and is all unfavorable concerning the afforestation of the protection of fir resource in imminent danger and fir forest.
Summary of the invention
The purpose of this invention is to provide a kind of seedling-cultivating method that impels the fast rapid-result seedling of fir,, in the greenhouse, utilize light source seedling to be shone light filling, promote the early nutrition growth of seedling at night by in fir growth of seedling process, thus fast rapid-result seedling.
In order to realize the object of the invention, after the semen-Abietis-Deliavayi fast seedling-nursing method that one aspect of the present invention provides is included in the fir planting seed, when cotyledon launches, seedling is carried out light filling every night.
The semen-Abietis-Deliavayi fast seedling-nursing method that the present invention provides on the other hand is included in after planting, and when cotyledon launched, to seedling light filling every night, the time of light filling was 8～10 hours every night.
Particularly, prior to seeding seed is carried out preliminary treatment vernalization, it is showed money or valuables one carries unintentionally or radicle is sowed when growing at least 1mm.Preliminary treatment comprises the fir seed with 0.3% liquor potassic permanganate seed disinfection, 4 ℃ of seed soaking husky Tibetan 10-20 days after 7-14 days down.
Particularly at the seedbed upper seeding wheel, wherein the seedbed preparation process comprises and chooses sheep excrement and peat composed of rotten mosses mixture as matrix, with liquor potassic permanganate it is sterilized, and scattering after vexed at least one week teds, the pot for growing seedlings of then this matrix being packed into, and matrix is watered permeable.Seed is broadcast covering liver moss on the back on the matrix in seedbed, after waiting to emerge liver moss is removed; Regularly water, apply fertilizer, temperature remains on 11～29 ℃ therebetween, and relative moisture remains on 50-70%.
Wherein, light filling employing artificial light source is one or more in sunlight color dysprosium lamp, high-pressure sodium lamp and the incandescent lamp.The light filling light intensity is 8-16 μ molm
-2S
-1, preferred light intensity is 12 μ molm
-2S
-1The light filling cultivation is at least 10 months period, is preferably 10 to 12 months.After preferably stopping light filling, seedling is practiced in beginning outside the greenhouse at the beginning of 5 months, in the afforestation in September then of practicing seedling.
The advantage of semen-Abietis-Deliavayi fast seedling-nursing method of the present invention is: greatly promoted the height growth of nursery stock by artificial light filling, experimental data shows: the height of seedling when adopting the inventive method to cultivate 20 months is more than 2 times of fir seedling height of seedling that adopt the same period common seedling-cultivating method to cultivate, therefore make growing-seedling period shorten to 1.5 to 2.5 years, and the growing-seedling period of existing fir seedling-cultivating method is generally 4-5, the growing-seedling period of the inventive method has shortened at least 1.5 years by contrast, has therefore saved human and material resources and time loss greatly.
