Description
Technical field
The invention belongs to nursery stock sexual reproduction technique fields, are related to the method for culturing seedlings of Hainan wind nanmu, and in particular to a kind of
The method for cultivating seedlings of Hainan wind nanmu.
Background technique
Hainan wind nanmu (Horsfieldia hainanensis Merr.) is that Myristicaceae wind Phoebe arbor fallen leaves are tall
Wood is distributed in China Hainan, south Guangxi, south of Yunnan, is born in 400-450 meters of height above sea level of mountain valley, the dark and damp thick forest in hills, is
National Top-rated protected wild plants, Chinese endemic plant.Hainan wind nanmu is a kind of extraordinary medicinal plant, bark and
Leaf can treat infantile malnutrition, and civil steep in wine with its bark or leaf of the Li nationality can be used as the tonic that women enriches blood, invigorates blood circulation in postpartum,
It is locally known as " celestial being's blood ", " blood tree "；Generally have from the alcohols in the ethereal oil extracted in its leaf and makes us emerging
The harmonicity smell put forth energy and there are the characteristics such as anti-corruption, anti-filterable virus；Terpenoid have refresh oneself, antibacterial anti-inflammatory and town
The effects of pain；Its seed oil content is high, and main fatty acid component is myristic acid and lauric acid.Wind nanmu seed oil is machine
Tool lubricating oil increasing stick pour point depression dual-purpose additive, " win honour for tree " is known as in the special age, is also to provide lauric acid and nutmeg
The important source material of acid has preferable value of exploiting and utilizing.Its timber cerise, can make noble furniture, and decoration, box timber etc. are used
On the way, it grows very fast, can cultivate one of big-diameter wood and torrid areas fast-growing commerical tree species, and therefore, Hainan wind nanmu is a kind of
With the energy, precious material and the multipurpose tree species such as medicinal.
Since wind nanmu resource in Hainan is considerably less, seed is rare, and it is endangered species that natural regeneration is difficult.Therefore, to Hainan wind
It blows nanmu seeding and seedling raising technology to be studied, improves seed germination rate and nursery stock rate, explore a kind of effective Hainan wind nanmu
Seeding growing seedlings method has great importance.
Currently, it is few to the research of Hainan wind nanmu nursery both at home and abroad, the seedling fostering of Hainan wind nanmu is reported, at present
Only Qinzhou City's forestry scientific research carries out this research.
Summary of the invention
The purpose of the present invention is establishing a kind of method for cultivating seedlings of Hainan wind nanmu, improves seed germination rate and nursery stock goes out
Garden rate is solved the problems, such as since germ plasm resource is few, seed seldom causes breeding difficult.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of method for cultivating seedlings of Hainan wind nanmu, including seed treatment, the outfit of matrix, sowing, small transplantation of seedlings, shifting
The step of managing and protecting after cultivation specifically comprises the following steps:
Step 1) seed treatment: it after Hainan wind nanmu seed adopted back is removed crust and aril, is put into clear water clear
Wash clean is placed in interior and dries in the air to epidermis drying, then uses fenaminosulf or liquor potassic permanganate by seed immersion treatment, after draining
For use；
Step 2) matrix is equipped with: after carbonized rice husks and the peat soil sterilized are mixed thoroughly in proportion, being respectively charged into seedling-growing container
With it is spare in Seedling bag；
Step 3) sowing: the seed handled well is seeded in and has been already equipped in mixed-matrix seedling-growing container, shade is placed in
It is inside cultivated, and covers film and carry out moisturizing, and observe the humidity of matrix daily；
The small transplantation of seedlings of step 4): as the small height of seedling 5cm that the seed for being seeded in seedling-growing container is grown, and there are two true leaf expansion
When, seedling is moved on in the Seedling bag being already equipped in mixed-matrix, water of drenching after transplanting is placed in negative canopy and is cultivated；
It is managed and protected after step 5) transplanting:
Daily water drenching after small transplantation of seedlings keeps seedling medium wet, it is ensured that seedling survives；
10 days after transplanting, seedling all goes out new root, carries out first time fertilising at this time, and fertilising is primary weekly, and with seedling
It grows up and increases fertilising concentration；
Pay attention to the prevention and control of plant diseases, pest control, periodically sprays；
Cleaning dead leaf, dead leaf and weeds in time, keep nursery sanitation and hygiene, reduce germ and breed, and guarantee nursery stock health
Growth.
It is with fenaminosulf or height with fenaminosulf or liquor potassic permanganate by seed immersion treatment described in step 1) of the present invention
For potassium manganate solution by seed immersion treatment, fenaminosulf concentration is 800 times of liquid, and liquor potassic permanganate is 1.5 ‰, soaking time 5-
10 minutes.
Matrix described in step 2) is equipped with, and the carbonized rice husks and the peat soil sterilized are according to volume in proportion
Ratio, carbonized rice husks+peat soil is 3:1, carbonized rice husks+peat soil is 1:3.
Seedling-growing container specification described in step 2) are as follows: length × width × height=50 × 30 × 7cm, Seedling bag specification are as follows: long × wide
=18 × 25cm.
The humidity of daily observation matrix described in step 3), is half dry and wet.
It is managed and protected after the step 5) transplanting, is:
Daily water drenching after small transplantation of seedlings keeps seedling medium wet, it is ensured that seedling survives；
10 days after transplanting, seedling all goes out new root, carries out first time fertilising at this time, and the fertilizer used that applies fertilizer for the first time is N:P:K
For the compound fertilizer of Finland or compound fertilizer of Denmark of 15:15:15, fertilising requires to follow the principle of " a small amount of multiple ", and fertilising is primary weekly,
And increasing fertilising concentration with growing up for seedling, the concentration of top dressing is the rich water solution of 0.3-0.5%；
Pay attention to the prevention and control of plant diseases, pest control, periodically spray, carries out pest control with 90% metrifonate, 1500 times of liquid sprinklings, use first
1000 times of liquid progress diseases prevention processing of base thiophanate, carbendazim, octicin solution；
Cleaning dead leaf, dead leaf and weeds in time, keep nursery sanitation and hygiene, reduce germ and breed, and guarantee nursery stock health
Growth.
Compared with prior art, the present invention has the advantage that
1, in the prior art, sowing average germination rate is 91.6%, sows average germination rate using the method for the present invention and reaches
98.6%, the germination rate than the prior art improves 7%.
2, it in the prior art, transplants in seedling culture, seedling growth is poor, and leaf color is partially yellow, and the outplanting rate for seedling of afforesting is
92.1%；Using in the small transplantation of seedlings culture of the method for the present invention, seedling robust growth, leaf color are dark green, and semi-annual height of seedling is
56.5cm, the height of seedling than the same seedling age of the prior art have been higher by 7cm, and the seedling outplanting rate that can afforest is up to 98.0%, compare the prior art
It has been higher by 5.9%.
