The preparation method is novel and controllable, and the consumption is low.
Description
Technical field
The present invention relates to the afforestation technology field, be specifically related to arid area short of rain afforestation with soil culture medium and preparation method thereof.
Background technology
China's arid is vast in territory, is to receive desertification to influence one of the most serious country in the world.Afforestation, it is very urgent to improve the ecological environment.The dry has the soil property desertification mostly, nutrient is poor, rainfall is rare, the characteristics of antecedent soil moisture.Dull with soil culture medium and preparing method's method to dry-land afforestation at present, technology content is lower, and the surrival rate of afforestation is not high.
CN1305696 discloses a kind of drought-resistant water-preserving nutritive soil, and its composition by weight is: 80～90 parts of vegetable mould, the base soil of 10～20 parts of formations of vegetable garden soil adds 2～3 parts of composite fertilizers again, 1～1.5 part of water-holding agent, 0.07～0.155 part of trace element.
CN101543178 discloses a kind of environment-friendly method for drought-resistant afforestation on sandy land, and step is: the plantation hole is opened in (1) on sand ground, its density is decided according to the difference of local rainfall amount; (2) one deck degradable plastics film in lower floor shop, hole spreads one deck agricultural crop straw on the film, after the treelet of planting; (3) the degradable plastic sheeting for farm use is covered in the tree planting back on the hole, stops up sand on the film, and the while is beaten irrigation hole in lowest concave; (4) the preparation diammonium phosphate aqueous solution is loaded in the irrigation tank, through aqueduct and drip irrigation pipe water is caused irrigation hole; (5) treelet is watered when fostering, and the drip irrigation pipe outlet is inserted in the irrigation hole, opens water control valve and waters, and controls certain flow velocity.This method needs the later stage maintenance.
The defective that above prior art exists is: (1) disposable water storage is low, is difficult to keep lastingly the demand of arid region plant to moisture; (2) the soil culture medium physical structure is unreasonable, and the disposable water excess that adds can cause root system death by suffocation; (3) nutritive ingredient is unbalanced, and fertilizer efficiency is short, lacks the auxiliary agent of taking root.
Summary of the invention
The purpose of this invention is to provide a kind of afforestation with soil culture medium and preparation method thereof, to solve the above-mentioned technical problem that prior art exists.
The technical scheme that the present invention taked is that a plant growth soil culture medium is made up of the material of following volume ratio: clay 25～30%; Wilkinite 2～3%; Organic 30～35%; Vegetable fibre 10～15%; Granule agent 0.03～0.05%; Water-holding agent 0.1～0.3%; Controlled-release compound fertilizer 0.5～0.8%; Root-inducing powder 0.0005%; Clear water 17～32%.
Described clay is one of main carrier of plant-growth, is common table soil in locality or deep layer clayey soil.
Described wilkinite is to be master's the sodium base or the moisture clay pit of calcium base type with the smectite; Smectite content is at 85-90%; Have stronger water absorbability and swelling property, adsorbable 8～15 times to the water yield of own vol, help promoting substratum to form crumb structure with granule agent effect.
Described organic matter also is one of main carrier of plant-growth, except playing getting fat, water conservation, gas-pervious effect, suitable suitable living environment can also be provided for the mikrobe in the substratum.This organic matter is that in stalk, trees brush wood, rice husk, saw powder, industrial plant class tankage such as vinasse, the dregs of a decoction etc. of selecting farm crop for use one or more are as raw material, through link preparation productions such as primary election, pulverizing, fermentation reactor system, dry metering, packings.This organic matter C/N ratio is controlled between 20～30:1.
Described vegetable fibre is the flocculence lignocellulose.Vegetable fibre also has the adsorption fertilizer effect except playing water conservation, function of fertilizer retention.
Described agent is polyacrylic ester; Mainly be in this preparation method, to make the mud compound that the granuleization reaction takes place, let substratum form good crumb structure.
Described water-holding agent is a kind of nontoxic, harmless Powdered polymer organic polymer, does not pollute plant, soil and underground water, finally is decomposed into carbonic acid gas, water, ammonia too nitrogen and sodium or potassium ion, does not have any residual.Water-holding agent can absorb the moisture from about 400 times of weight, has quick suction, slowly discharges, and promotes the characteristics of plant absorbing, and the water-saving that therefore can preserve soil moisture effectively suppresses the effect of moisture evaporation.
Described controlled-release compound fertilizer total nutrient content (being meant the content of " nitrogen, phosphorus, potassium ") is 40～45%, and nitrogen, phosphorus, potassium ratio are 1:1:1.The slow release of may command fertilizer, the validity that prolongs fertilizer satisfies the nursery stock nutrient and supplies with for a long time.
Described root-inducing powder is No. 3, ABT, and the concentration range of its aqueous solution is 10mg/kg～50mg/kg.Root-inducing powder is a kind of compound efficient, broad-spectrum plant root-inducing promoter, the vigor field planting early that helps improving root system of plant.
The clear water pH value that the present invention uses is 6.5～7.5, must not use salt and alkali component content height to the deleterious water of plant-growth.
A kind ofly prepare the above-mentioned method that is suitable for the soil culture medium that dry-land afforestation uses, comprise the following steps:
A, the clay with said ratio, wilkinite, organic matter, vegetable fibre, water-holding agent, root-inducing powder, fertilizer join and fill in the proper amount of clear water container, evenly stir 6～12 minutes, obtain the mud compound.
B, in another container, inject earlier proper amount of clear water (temperature is advisable at 15 ℃～30 ℃), the granule agent that adds formula rate was again stirred after 10～15 minutes, obtained an agent solution.Put into the clear water total amount in this A, the B step for twice and should meet the requirement of described " clear water 17～32% " (accounting for the volume ratio of prescription total amount).
C, the granule solution gradation that the B step is made add in the mud compound of A step, fully mix, and till obviously seeing soil and water sepn, this reaction process is the soil granular reaction;
The excessive moisture that occurs in the granuleization reaction of D, the C step of draining, the soil that obtains are and are suitable for dry-land afforestation and use soil culture medium.
Described soil culture medium physical and chemical index is: substratum unit weight 0.6～1.2/cm
3The effective water holding capacity volume ratio of substratum>=50%; Porosity: 55～65%; Organic matter>=40g/kg; Full nitrogen>=1.3g/kg; Full phosphorus>=1.3g/kg; Full potassium>=8g/kg; PH value is 6.0～7.5; Specific conductivity (EC) is 1.5～3.0ms/cm; Cation exchange capacity>=18me/100g.
Each related component uses the volume ratio of soil culture medium to be with the dry-land afforestation that is suitable for that makes: clay 25～30%; Wilkinite 2～3%; Organic 30～35%; Vegetable fibre 10～15%; Granule agent 0.03～0.05%; Water-holding agent 0.1～0.3%; Controlled-release compound fertilizer 0.5～0.8%; Root-inducing powder 0.0005%; Clear water 17～32%.
The present invention is fit to the soil culture medium of dry-land afforestation, and it has the nutrient abundance, good water conservation, fertile, the permeability of guarantor; Has good crumb structure; Contain the auxiliary agent of taking root, can promote the new root of nursery stock and premature eruption; Used fertilizer is the slowly-releasing state, and the nursery stock nutrient can be provided lastingly.Be fit to very much dry-land afforestation and use culture substrate.This soil culture medium can be used general spray seeder preparation, afforests with culturing pot (grant number is ZL 200910017663.3) in conjunction with a kind of afforestation that our company announces, more helps improving the working efficiency of dry-land afforestation and the surviving rate of nursery stock.
Embodiment
Below in conjunction with concrete afforestation embodiment to the detailed description of the invention.
