Abstract
The invention discloses a method of cold-resisting cultivation method of transplanting seedlings of needle-leaved trees in cold and arid regions, in order to solve an overwintering problem of the transplanting seedlings of needle-leaved trees in arid regions of northwest China. The cold resisting method comprises steps of nursery field selection, normal field management, two times of winter water irrigation and arranging chemical agent for cold resistance. In early and middle of August and early of November, the Handilong nutritional agents are used for spraying leaf surfaces. Before the soil is frozen, Bordeaux mixture containing copper sulfate and lime with proportion of 1:1.5-2 and starch emulsion are prepared to spray the transplanting seedlings of needle-leaved trees. According to the invention, resistance and adaptability of nursery stocks of transplanting seedlings of needle-leaved trees are remarkably improved; cold resistance of the seedlings is improved; survival rate of seedlings is increased; damage of tree forms caused by soil burying during overwintering in winter is avoided; seedling recovering period is reduced; time and labor are saved; cold resistance and adaptability of the seedlings are improved; survival rate of forestation, ornamental value of the needle-leaved trees and performance of commodities are greatly improved; and the cold resisting method is widely applicable for forestry production and ecological construction in cold and arid regions.
Description
Technical field
The invention belongs to planting tree field, be specifically related to the northwest drought-hit area coniferous tree that trembles with fear and change the wintering method of a seedling.
Background technology
Coniferous species due to its whole year evergreen, tree-like grace, is widely used in afforestation and ecological construction, particularly to tremble with fear in northwest drought-hit area, greening evergreen species are few, and winter, view was single, and coniferous tree plays an important role in afforestation and Ecological Project Construction.
Owing to trembling with fear in northwest, drought-hit area cold very long drying in winter is windy, temperature Change is violent, winter to early spring, nursery stock easily suffered freeze injury or " physiological drought ", plant local is drained, light then part branch is injured, heavy then can complete stool dead, had a strong impact on nursery stock normal growth, coniferous tree change in a seedling show comparatively general.
The many employings of current Coniferous Seedling-raising initial stage seedling overwintering are buried soil and to be survived the winter method, by seedbed seedling whole earthing 20-30 cm, treat that spring fetches earth again.As long as suitable operation, seedling bed seedling all can safe overwintering, and it is poor that more than 30 centimetres coniferous tree seedling change a field planting primary growth resistance, and growth potential is weak, and seedling-slowing stage is long, if do not have the freeze prevention measure of surviving the winter of safety extremely should cause nursery stock freeze injury, suffers heavy losses; In production, normal employing is buried soil and to be survived the winter cold-proof method, to prevent air-dry and freeze injury in nursery stock winter, improves plant percent.But nursery lot changes a seedling and investigation mission outside the city or town seedling in a large number and adopts at the field planting initial stage that mounding is not only time-consuming takes a lot of work, and easily causes very big destruction to tree-like, also easily injures seedling, reduce its sight, affect commodity performance when spring fetches earth.
Summary of the invention
The object of this invention is to provide the method that a kind of cold drought-hit area coniferous tree changes the cold-resistant cultivation of a seedling, to solve the winter issue of Northwest arid district coniferous tree seedling.
For solving above technical problem, the technical solution used in the present invention is as follows: a kind of cold drought-hit area coniferous tree changes the cold-resistant method of a seedling, comprises the following steps:
(1) nursery lot is selected: change a seedling and select the nursery lot forest network is sound to carry out;
(2) conventional field management: in late April, changes a field planting to coniferous tree seedling, fill with field planting water, and in interval 7-10 days, make-up water again, to guarantee Survival rate of nursery stock;
(3) science fill with winter water: after entering the winter, ground temperature is lower than 5 DEG C before filling 1 time permeable, ground temperature lower than 0 DEG C of temperature, then fills with 1 water;
(4) chemical agent is cold-proof: at early and middle ten days and early November in August, spray blade face respectively with Handilong nutritional agents, before frozen soil, the ratio of preparation copper sulphate, lime be 1: 1.5-2 bordeaux mixture add starch emulsion spray needle leaf tree and change a seedling.
Preferably, conventional field management step, strengthens rich water in spring, promotes young sprout growth, shortens seedling-slowing stage, improve photosynthetic usefulness, ensures that tree body is healthy and strong; Autumn Controlled irrigation, use phosphorus potash fertilizer, deep ploughing is hoed up weeds, and promotes that branch terminates growth early, is conducive to tissue and enriches, and the integration time of prolongation nutriment, thus carries out Cold Acclimation better.
Preferably, the collocation method of described bordeaux mixture is: by copper sulphate with 2/3 the water yield dissolve, the water yield with 1/3 melts lime and forms milk of lime, is then poured in milk of lime by copper sulfate solution, and constantly stirs, and two liquid is mixed, can be made into bordeaux mixture.
The present invention is specifically related to the northwest coniferous tree such as more than 30 centimetres, drought-hit area (or life in three, four years) pinus sylvestris var. mongolica, Chinese juniper, needle juniper, dragon spruce that tremble with fear and changes the overwintering technology of a seedling, new afforestation coniferous tree seedling.
This method key technology be perfect protection forest net, science fill with winter water and chemistry cold-proof, be called for short " 123 " cold-proof method." 1 " namely selects ground field planting coniferous tree in a protection forest net sound garden to change a seedling; " 2 " filling 2 winter water, after namely entering the winter, before ground temperature is lower than 5 DEG C fill with 1 time permeable, ground temperature is lower than 0 DEG C, and soil because of moisture and icing, then fills with 1 water, is not drained to keep root system by wind.When the temperature is lower, root freezes water can release latent heat, improves temperature; It is cold-proof that " 3 " refer to spray 3 chemical agents.I.e. August, early November, twice 400 times of Handilong liquid are sprayed on blade face, and to improve acerose resistance, before frozen soil, the bordeaux mixture sprinkling coniferous tree that preparation strengthens amount of lime changes a seedling.
Beneficial effect of the present invention is as follows: cultivation method of forming a complete and comprehensive system for collecting real estate fees of the present invention, efficiently solve the northwest drought-hit area coniferous tree that trembles with fear and change the problem of a seedling and new afforestation seedling cold resistance difference, significantly improve Coniferous seedling resistance and adaptability, strengthen seedling cold resistance, improve nursery stock survival rate of seedlings, avoid surviving the winter winter because burying the tree-like destruction made from local methods, shorten seedling-slowing stage, time and labour saving, save seedling cost, strengthen seedling cold resistance and adaptability, shorten seedling-slowing stage, greatly improve survival rate and acerose sight and commodity performance, the production of forestry of cold drought-hit area and ecological construction can be widely used in.
