Abstract
The invention relates to a method for preparing a desert plant seedling raising substrate. According to the method, the seedling raising substrate is prepared from sandy soil, magnesium sulfate, thoroughly-decomposed cow dung and a water retention agent and is prepared through the steps of selecting the sandy soil with water permeability and moisture retention, carrying out salt content determination on the selected sandy soil so as to obtain the content of magnesium sulfate in the sandy soil, determining the added amount of desulfurization magnesium slag according to the content of magnesium sulfate in the sandy soil, adding the thoroughly-decomposed cow dung into the sandy soil, uniformly stirring and mixing, adding the high-hygroscopicity water retention agent, and uniformly stirring and mixing, thereby obtaining the desert plant seedling raising substrate. The method has the advantages that the moisture absorption and water retention properties of desulfurization magnesium slag are utilized, so that the moisture content of the seedling raising substrate is increased, the seedling emergence rate and survival rate of seedlings are increased, the seedling emergence cycle is shortened, and the quality of the seedlings is improved; through carrying out seedling raising by using the seedling raising substrate prepared by the method provided by the invention, the seedling emergence rate can reach 95%, the survival rate can reach 90%, the seedling raising is not subjected to seasonal restrictions, and the seedlings can be supplied all the year, so that the method has an important practical significance in the large-scale production of desert plant seedlings and the restoration and reconstruction of vegetation in desert vegetation damaged areas.
Description
Technical field
The invention belongs to eremophytes seedling growing process field, be specifically related to the compound method that culture matrix is bred in a kind of eremophytes nursery.
Background technology
In NORTHWEST CHINA Desert Area, ecotope is very fragile, although deserta species are less, cover degree is lower, constitutes the main body of desert ecosystem, to resisting the natural calamities such as dust storm, stablizes arid biogeographic zone environment and plays a part can not be ignored.But mankind's activity is violent all the more on the impact of natural environment, and large-area desert ecosystem is destroyed, makes natively very fragile desert ecosystem impaired or degenerate, cause a series of ecological environment problem.For improving natural environmental condition; natural disaster reduction; the living safety of the protection mankind; large-area vegetation restoration and reconstruction engineering has all been carried out in various places; eremophytes species become first-selected reproducting tree species; but too low owing to applying existing eremophytes seedling growing process emergence rate, nursery stock quality is not high, can not meet the nursery stock demand of current reconstruction engineering far away.
In the seedling medium of existing routine; not containing water-loss reducer and desulphurizing magnesium slag; the emergence rate of eremophytes nursery only has 30%-50%, and the seedling medium prepared by the present invention carries out nursery, and emergence rate can reach 95%; survival rate can reach 90%; and be not subject to seasonal restrictions, can be annual for seedling, for large-scale production eremophytes nursery stock; carry out vegetation restoration and reconstruction in deserta damaged zone, there is important practice significance.
Existing report desulphurizing magnesium slag was only applied in artificial afforestration.
Summary of the invention
Order of the present invention is, a kind of compound method of eremophytes seedling medium is provided, the method is made up of sandy soil, magnesium sulfate, the cow dung become thoroughly decomposed and water-loss reducer, adopt and choose the sandy soil with water penetration and moisture retention, salinity mensuration is carried out to the sandy soil chosen, obtain the content of magnesium sulfate in sandy soil, the amount adding desulphurizing magnesium slag is determined again according to the content of magnesium sulfate in sandy soil, the cow dung become thoroughly decomposed is added in sandy soil, be uniformly mixed, add high-hydroscopicity water-loss reducer again, be uniformly mixed and namely obtain eremophytes seedling medium.The method utilizes the moisture-absorption water-retention performance of desulphurizing magnesium slag, increases the moisture of seedling medium, improves seedling emergence rate and survival rate, shortens and emerges the cycle, improves seedling quality.The seedling medium prepared by the method for the invention carries out nursery; emergence rate can reach 95%; survival rate can reach 90%; and be not subject to seasonal restrictions; can be annual for seedling; for large-scale production eremophytes nursery stock, carry out vegetation restoration and reconstruction in deserta damaged zone, there is important practice significance.
The compound method of a kind of eremophytes seedling medium of the present invention, in the method, seedling medium is made up of percentage by weight sandy soil 76-84%, magnesium sulfate 0.5-1.5%, the cow dung 15-21% become thoroughly decomposed and water imbibition water-loss reducer 0.5-1.5%, and concrete operations follow these steps to carry out:
A, choose the sandy soil with water penetration and moisture retention;
B, salinity mensuration is carried out to the sandy soil chosen: sampled by sandy soil, after drying in the shade, sieving, analyze the SO measured wherein according to a conventional method
4 2-, Mg
