Abstract
The tree-grass complex formula that afforestation effect can be optimized the present invention relates to one kind digs dibbling seedling-growing method, grass seeds with nitrogen fixation of the sowing Jing Guo seed treatment on the loosened soil on the cave surface of planting seedlings for transplanting sapling, or the turf cultivated using the grass seeds with nitrogen fixation is laid on the cave earthing that plants seedlings for transplanted sapling, after kind grass or grass planting process, i.e. realization tree-grass complex formula digs dibbling seedling.This dibbling seedling-growing method that digs can not only prevent from planting seedlings the loss of soil moisture in cave, but also can inhibit weed invasion, can also increase the increase in standing timber, actual effect is very good.This method has broken the traditional concept for the grass that afforestation must be removed in cave of planting seedlings, and it is utilized in the grass seeds being sown into cave of planting seedlings with nitrogen fixation or is implanted into the turf cultivated using the grass seeds with nitrogen fixation, to reaching cave water conservation of planting seedlings, preventing weed invasion and increasing the target of the increase in standing timber, have the effect of ideal, popularization and application foreground is considerable.
Description
Technical field
The present invention relates to forestry afforestation technologies, and in particular to the tree-grass complex formula that one kind can optimize afforestation effect digs cave
It plants seedlings method.
Background technique
In existing Technical regulations for afforestation, digging dibbling seedling is the forest planting method that most of areas use, and is constituted this
The essential step of forest planting method are as follows: clear woods, site preparation such as dig cave, plant seedlings and foster at the processes.The shortcomings that this method is
The original ecological environmental condition in cave of planting seedlings is changed during afforestation, causes vegetation stability and soll layer structure by broken
It is bad, to further result in soil moisture loss and weed invasion in cave of planting seedlings.2-5 must be carried out after especially planting seedlings
Foster, to guarantee final afforestation survival rate and retention rate.Along with afforestation place is mostly forest land and wasteland, nursery stock after afforestation
Nutrition supply can only be from the nutrient in the original soil of nursery stock.The defect of this forest planting method never obtains gram
How clothes, guarantee that nursery stock well grows and increase afforestation survival rate and retention rate, be always the afforestation technology personnel head to be solved
Want problem.
Summary of the invention
The object of the present invention is to provide a kind of losses of soil moisture in cave that can not only prevent from planting seedlings, but also can inhibit weeds
Invasion, the tree-grass complex formula for optimizing afforestation effect that can also increase the increase in standing timber dig dibbling seedling-growing method.
The technical solution of the invention is as follows:
It is a kind of optimize afforestation effect tree-grass complex formula dig dibbling seedling-growing method, it the following steps are included:
(1), site preparation: sundries is disposed into the soil that preparation is used for planting by stock and is handled smooth；
(2), dig cave of planting seedlings: the size on the forest land of smooth mistake according to sapling digs out the cave of planting seedlings of appropriate depth and shape；
(3), it plants seedlings: the sapling cultivated is transplanted to planting seedlings in cave of having dug, fill out after half soil and mention seedling and tread, then fill out another
Half soil is treaded, last covered one layer of loosened soil；
(4), kind grass or grass planting: sowing has fixed nitrogen by seed treatment on the loosened soil on the cave surface of planting seedlings for transplanting sapling
The grass seeds of effect, then be covered with earth mulch and live grass seeds, earthing is stepped on, gently then to guarantee close contact and the grass seeds hair of grass seeds and soil
Bud, or be laid with the turf cultivated using the grass seeds with nitrogen fixation on the cave earthing that plants seedlings for transplanted sapling, plant grass or plant
After careless process, i.e. realization tree-grass complex formula digs dibbling seedling.
Site preparation step includes removing shrub, weeds, logging residue and leveling land.
Used grass seeds is locally can overwintering, the rapid grass seeds with nitrogen fixation of growth.
Grass seeds with nitrogen fixation should be full, mature, no disease and pests harm grass-seed.
The used grass seeds with nitrogen fixation grow up after maximum height be no more than sapling height half or
(clover may be selected when Yun Lengshan, Korean pine afforestation in one third；Alfalfa, sweet clover etc. may be selected when poplar, willow afforestation
Grass seeds).
The method of seed treatment is the disinfecting solution of potassium permanganate first with 5%, and the higher seed of hard seed rate is needed using dense
Sulfuric acid is pulled clear water out after impregnating 10-20 minutes and is rinsed well, and no hard seed rate and the lower seed of hard seed rate are without using the concentrated sulfuric acid
Impregnate, and need to pull out after being impregnated 6-24 hour with clear water, the seed by above-mentioned processing be blended into a small amount of wet fine sand and
Grass seeds is puddled uniformly.
The method of sowing grass seeds is to broadcast sowing, drilling, mixed seeding or sow grass seeds by duster.
It is laid with shading net after planting to guarantee the germination as early as possible and good growth of grass seeds.
The solution have the advantages that: this dibbling seedling-growing method that digs can both prevent from planting seedlings the loss of soil moisture in cave,
It can inhibit weed invasion again, the increase in standing timber can also be increased, actual effect is very good.This method has broken afforestation must
The traditional concept of the grass in cave of planting seedlings must be removed, and is utilized in and is sown into grass seeds or implantation benefit with nitrogen fixation in cave of planting seedlings
The turf cultivated with the grass seeds with nitrogen fixation, to reach cave water conservation of planting seedlings, prevent weed invasion and increase tree growth
The target of amount, has the effect of ideal, and popularization and application foreground is considerable.
Tree-grass complex formula of the present invention digs the advantages of dibbling seedling-growing method:
1, this method effectively reduces scattering and disappearing for soil moisture in cave of planting seedlings, thus Survival rate of nursery stock caused by solving because of spring drought
The low problem of rate.
2, this method can accelerate the speed of emergence of grass-seed, improve the emergence of grass-seed by carrying out seed treatment to grass-seed
Uniformity.
3, after rapid, a lower height of grass seeds of growth is introduced in cave of planting seedlings according to this method, the grass seeds energy in cave of planting seedlings
It is enough quickly to form population advantage in a short time, the invasion of weeds can be inhibited, so that the subsequent number fostered is further reduced,
Even without the environmental condition that can improve nursery stock periphery by fostering.
4, this method is chosen, and there is the grass seeds of nitrogen fixing capacity to be introduced into cave of planting seedlings, improve the nutrition of soil in cave of planting seedlings at
Point, nitrogen needed for providing seedling-nourishing growth to a certain extent, so as to improve the increment of nursery stock.
Although 5, mode that this method introduces grass seeds increases cost of forestation in afforestation early period, after application this method by
In the cost that can reduce afforestation later period tending ot young growth, and the surrival rate of afforestation and the increase in standing timber are effectively increased, so comprehensive
From the point of view of, cost of forestation of the present invention and effect are with greater advantage.
6, this method is simple and easy, and operating cost is low, can promote on a large scale, provides for afforestation a kind of complete
New operational means is worth promoting and applying in national most area.
