Abstract
A method for seedling cold-resistant cultivation is changed the invention discloses a kind of cold drought-hit area coniferous tree, to solve the winter issue of Northwest arid district coniferous tree seedling.This method comprises the following steps：Nursery lot selection, conventional field management, filling winter water 2 times, chemical agent are cold-proof.In August early and middle ten dayses and early November, sprayed respectively with Handilong nutritional agents before blade face, frozen soil, prepare copper sulphate, the ratio of lime adds starch emulsion spray needle leaf tree to change a seedling for 1: 1.5 2 Bordeaux mixture.The inventive method significantly improves Coniferous seedling resistance and adaptability, strengthen seedling winter resistance, improve nursery stock survival rate of seedlings, it is to avoid winter survives the winter because burying the tree-like destruction made with local methods, shortens seedling-slowing stage, time and labour saving, seedling cost, enhancing seedling winter resistance and adaptability are saved, shortens seedling-slowing stage, the surrival rate of afforestation and the sight and commodity performance of coniferous tree are greatly improved, cold drought-hit area production of forestry and ecological construction is can be widely applied to.
Description
Technical field
The invention belongs to planting tree field, and in particular to the cold drought-hit area coniferous tree in northwest changes the wintering method of a seedling.
Background technology
Coniferous species is evergreen due to its whole year, tree-like grace, is widely used in afforestation and ecological construction, especially
It is drought-hit area of being trembled with fear in northwest, greening evergreen species are few, and winter landscape is single, and coniferous tree sends out in afforestation and Ecological Project Construction
Wave important function.
Because northwest cold very long drying of cold drought-hit area winter is windy, temperature Change is violent, winter to early spring nursery stock easily meets with
By freeze injury or " physiological drought ", plant is locally drained, gently then part branch is aggrieved, it is heavy then can complete stool it is dead, have a strong impact on
Nursery stock normal growth, changes in coniferous tree and shows more universal in a seedling.
Survived the winter method more than current Coniferous Seedling-raising seedling overwintering at initial stage using burying soil, i.e., by seedbed seedling whole earthing 20-30
Cm, treats that spring fetches earth again.As long as suitable operation, seedling bed seedling can safe overwintering, more than 30 centimetres coniferous tree seedling change bed
Field planting primary growth resistance is poor, and growth potential is weak, and seedling-slowing stage is long, if the freeze prevention measure of surviving the winter without safety extremely preferably causes nursery stock to freeze
Evil, suffers heavy losses；Production is upper to survive the winter cold-proof method, to prevent nursery stock winter from air-drying and freeze injury, raising Survival rate of nursery stock frequently with burying soil
Rate.But nursery lot largely changes a seedling and investigation mission outside the city or town seedling and taken a lot of work at field planting initial stage using mounding is not only time-consuming, and hold to tree-like
Very big destruction is easily caused, seedling is also easily injured when spring fetches earth, its sight is reduced, influences commodity performance.
The content of the invention
A method for seedling cold-resistant cultivation is changed it is an object of the invention to provide a kind of cold drought-hit area coniferous tree, is done with solving northwest
The winter issue of drought-hit area coniferous tree seedling.
To solve above technical problem, the technical solution adopted by the present invention is as follows：A kind of cold drought-hit area coniferous tree changes a seedling
Cold-resistant method, comprises the following steps：
（1）Nursery lot is selected：A seedling selection is changed to carry out in the nursery lot that forest network perfects；
（2）Conventional field management：In late April, coniferous tree seedling is carried out to change bed field planting, field planting water is filled, and be spaced 7-
In 10 days, make-up water again, to ensure Survival rate of nursery stock；
（3）Science fills winter water：Enter after the winter, 1 permeable, less than 0 DEG C temperature of ground temperature was filled before ground temperature is less than 5 DEG C, then fill 1
Secondary water；
（4）Chemical agent is cold-proof：In August early and middle ten dayses and early November, blade face, soil are sprayed with Handilong nutritional agents respectively
Before freezing, copper sulphate is prepared, the ratio of lime adds starch emulsion spray needle leaf tree to change a seedling for 1: 1.5-2 Bordeaux mixture.
It is preferred that, conventional field management step strengthens rich water in spring, promotes young sprout growth, shortens seedling-slowing stage, improves light
The efficiency of cooperation, it is ensured that tree body is healthy and strong；Autumn Controlled irrigation, using phosphorus potash fertilizer, deep ploughing is hoed up weeds, and promotes branch to terminate life early
It is long, be conducive to tissue to enrich, extend the integration time of nutriment, so as to preferably carry out Cold Acclimation.
It is preferred that, the collocation method of the Bordeaux mixture is：Copper sulphate is dissolved with 2/3 water, with 1/3 water
Lime is opened into milk of lime, then pours into copper sulfate solution in milk of lime, and is stirred continuously, is well mixed two liquid, you can to match somebody with somebody
Into Bordeaux mixture.
Trembled with fear more than 30 centimetres of drought-hit area present invention relates particularly to northwest（Or three, lifes in 4 years）Pinus sylvestris var. mongolica, Chinese juniper, needle juniper, dragon spruce
The overwintering technology of a seedling, new afforestation coniferous tree seedling is changed Deng coniferous tree.
This method key technology be perfect protection forest net, science fill winter water and chemistry it is cold-proof, referred to as " 123 " cold-proof method.“1”
Being colonized coniferous tree changes a seedling with selecting the sound garden of a protection forest net；" 2 " enter after the winter, in ground temperature 2 winter water are filled
Before less than 5 DEG C fill 1 time it is permeable, ground temperature be less than 0 DEG C, soil freezes because aqueous, then fills 1 water, to keep root system not taken out by wind
It is dry.When the temperature is lower, water is frozen in root can release latent heat, improve temperature；" 3 " refer to that to spray 3 chemical agents cold-proof.That is August, 11
In the first tenday period of a month moon, 400 times of Handilong liquid twice is sprayed on blade face, to improve before the resistance of coniferous tree, frozen soil, prepares and increases amount of lime
Bordeaux mixture sprinkling coniferous tree changes a seedling.
Beneficial effects of the present invention are as follows：The cultural method of forming a complete and comprehensive system for collecting real estate fees of the present invention, efficiently solves the cold drought-hit area pin in northwest
The problem of Ye Shu changes a seedling and poor new afforestation seedling winter resistance, significantly improves Coniferous seedling resistance and adaptability, strengthens
Seedling winter resistance, improves nursery stock survival rate of seedlings, it is to avoid winter survives the winter because burying the tree-like destruction made with local methods, shortens seedling-slowing stage, time saving province
Work, saves seedling cost, enhancing seedling winter resistance and adaptability, shortens seedling-slowing stage, greatly improve the surrival rate of afforestation and needle
The sight and commodity performance of tree, can be widely applied to cold drought-hit area production of forestry and ecological construction.
