Abstract
The invention discloses a method for quickly raising oak seedlings, which includes: soaking ripe high-quality oak seeds in cold water early on October, using drugs to kill pests and burying the seeds in sand for cold storage for reserve; sieving the yellow sand and tussah silkworm nursery soil with bacteria prior to packaging with humus pots early the next March, wherein the yellow sand is above the tussah silkworm nursery soil with bacteria; burying the treated oak seeds in the yellow sand in the humus pots, and sowing two to three oak seeds in each pot; placing the humus pots with sowed seeds in a greenhouse in order; controlling the interior greenhouse temperature to be 10-15 DEG C on March; controlling the interior greenhouse temperature to be 18-22 DEG C from the beginning of April; conforming the interior greenhouse temperature to the exterior natural temperature when the daily average exterior temperature reaches 20 DEG C; and transplanting the oak seedlings to a hill in the rainy season when the seedlings grow to 30-50cm high and roots grow to 10cm long after July. By means of the method, the root systems of the oak seedlings can grow fast, lignification degree of the seedlings is high, maturity time of the oak trees is shortened, and the tussah silkworm nursery can form soon.
Description
Technical field
The present invention relates to the seedling-cultivating method of a plant species, especially a kind of method of toothed oak tree fast seedling growing.
Background technology
The toothed oak tree is the main feed of tussah, is the basic living resources that the development tussah produces, and simultaneously, also is the important vegetation of China's Northeast Mountain Areas, is the fine tree species of greening and water and soil conservation.In recent years, along with the mass development utilization of tussah cocoon, toothed oak tree resource was obviously not enough, the tree vigo(u)r decline, and degenerate in the silkworm field.Therefore, increase silkworm field toothed oak stump number, increase output and be significant, also can increase vegetation simultaneously, prevent erosion, also have ecological significance for improving load silkworm amount.Rubber kind direct seeding technique is all adopted in existing construction silkworm field, owing to be open-air live, bud ratio is very low; The back seedling growth of sprouting receive factors such as temperature, moisture to influence survival rate very low; Even become to live, forming big tree also needed for 10 years, can not satisfy the needs that tussah is cultured and afforests.
Summary of the invention
The technical problem that invention will solve: a kind of toothed oak tree fast seedling-cultivating method is provided, adopts this method that toothed oak sapling root system is formed fast, seedling is done degree of lignification and is improved, and shortens the one-tenth tree time of toothed oak tree, forms tussah silkworm nursery early.
The technical scheme that the technical solution problem is taked: a kind of toothed oak tree fast seedling-cultivating method, the toothed oak tree is grown seedlings according to the following steps:
1) at the beginning of 10 months, get ripe good rubber kind with cold water soak after, behind the with medicament desinsection, it is subsequent use to be embedded in the sand refrigeration;
2) at the beginning of 3 months next years, the nutritive cube of packing into after yellow sand and tussah silkworm nursery mycorhiza soil sieved, the upper strata is a yellow sand, lower floor is a tussah silkworm nursery mycorhiza soil;
3) the rubber kind of the preceding step being handled well is imbedded 5cm depths in the yellow sand of nutritive cube, 2-3 rubber kinds of every alms bowl sowing;
4) place booth to put neatly nutritive cube after planting;
5) March, temperature of shed is controlled at 10-15 ℃;
6) rise April, temperature of shed is controlled at 18-22 ℃;
When 7) treating that the outer daily mean temperature of canopy reaches 20 ℃, suitably ventilate, make temperature of shed consistent with extraneous natural temperature;
8) after July,, when root length reaches 10cm, utilize rainy season that the toothed oak sapling is transplanted on the mountain when sapling highly reaches 30-50cm.
As improvement of the present invention: in step 1), the temperature of cold water is 0-5 ℃, and soak time is 36-48 hours, and refrigerated storage temperature is controlled at-10--15 ℃.
As further improvement of the present invention: in step 2) in, yellow sand and tussah silkworm nursery mycorhiza soil are by the volume ratio of the 1:1 nutritive cube of packing into, and the thickness of yellow sand layer is 8-12cm, and tussah silkworm nursery mycorhiza the thickness of the layer is 8-12cm.
Further improve again as of the present invention: in step 5), 6), 7) in, the relative moisture in the canopy is controlled at 60-70%.
Beneficial effect: owing to utilize the booth technology, built the microclimate that is suitable for rubber kind germinating growth in the present invention, employing method of the present invention is grown seedlings can more common mountain region direct sowing and seedling method be sowed in 3 months in advance; The people makes the toothed oak sapling increase by vegetative period of 3 months then in sowing, therefore, and when natural benign climate seedling growth; The toothed oak sapling that this method is cultivated reached for 3 monthly ages, can better absorb nutrition, carried out photosynthesis; And root system is formed fast, seedling is done degree of lignification and is improved, and just can transplant then and go up a hill; And common seedling nursery can be transplanted after taking 2 years at least and gone up a hill; Through 100 mu of tussah silkworm nursery tests in Venus township, Xifeng County, Liaoning Province, adopting the inventive method to cultivate the toothed oak sapling only needed for 5 years just can form the required Cheng Shu in silkworm field, live 5 years in advance of more common mountain region.Owing to adopt the method for raise seedling in greenhouse, be convenient to carry out artificial liquid manure centralized management, make the survival rate of sapling higher, growing way is better, normal growth rapidly after the transplanting.Owing to reasonably define the temperature and time of soaked in cold water, help killing the parasite in the rubber kind, and the rubber kind can be germinateed fast; Since reasonably define yellow sand and mycorhiza native cooperate ratio and soil thickness; Utilize the gas permeability of preserving moisture of upper strata yellow sand; The environment that is suitable for germinateing is provided for the rubber kind; Utilize the abundant nutrition of lower floor's mycorhiza soil, impel seedlings root to grow fast, make the toothed oak sapling of adopting this method to cultivate to grow fast; Owing to rationally define the air humidity in the booth, created more advantageous conditions for the quick growth of toothed oak sapling, the toothed oak sapling that has further promoted the inventive method to cultivate becomes a useful person early.
Embodiment
Do further explain in the face of technical scheme of the present invention down:
