A kind of tomato seedling substrate and its preparation method
Technical field
The invention belongs to seedling medium field, particularly to a kind of tomato seedling substrate and its preparation method.
Background technology
The main component of traditional seedling medium is turf and peat, is generally acknowledge in the world comparatively ideal
Cultivation matrix.But with using in a large number year by year, it gives the negative effect that society and ecological environment bring
Also become clear day by day, as non-renewable resources, excessive exploitation can have a strong impact on the balance of ecosystem.
Therefore, the resource situation according to Hexi prefecture, works out a kind of more efficient, more economical, more
Plus the seedling medium of environmental protection is the task of top priority.
Mushroom bran, animal excreta and Terramycin-type waste water just due to containing organic in a large number and nutritional labeling, and
Effectively use can alleviate environmental pollution and the wasting of resources, widely studied and apply.As in
State's patent CN101433176 discloses a kind of seedling medium with mushroom slag as primary raw material and its system
Method, the mushroom slag of processing, Vermiculitum, perlite, leaven are mainly mixed to prepare by by a certain percentage,
Although the method instead of turf with mushroom slag, employ Vermiculitum in traditional matrices formula, Margarita
Rock, inconvenience of drawing materials, high cost.Chinese patent CN103342596 disclose a kind of using paper sludge,
The tomato seedling substrate that mushroom slag and sand are made into is although saved cost, but paper sludge decomposed period is long,
And nutritional labeling is single.Disclose in Chinese patent CN102850128 a kind of using corn straw,
Cattle manure, the seedling medium of bacteria residue, perlite and EM culture fluid composition, this matrix nutrition balanced composition,
Using agriculture waste resource, reusable, but do not consider the water retention property of substrate, permeability,
And the impact to seedling quality for the substrate, and high expensive.
Content of the invention
In order to solve above-mentioned technical problem, a kind of present invention nursery effect of offer is good, seedlings root
Prosperity, good water-retaining property, rich in nutrition content, cheap tomato seedling substrate.
Concrete technical scheme of the present invention is as follows:
The present invention provides a kind of tomato seedling substrate, and described substrate is mainly former by following weight portion
Material is prepared from:Decomposed cow dung 3-4, perlite 2-3, bacillus subtilises 0.03-0.08,
Terramycin-type waste water 3-4.
Tomato seedling substrate provided by the present invention contains the organic in a large number and battalion such as nitrogen, phosphorus, potassium
Foster element, nutritious and equilibrium, it is more beneficial for the well developed root system of tomato seedling thus promoting to give birth to
Long;Fructus Lycopersici esculenti seedling medium of the present invention can also suppress the harmful substances such as pathogenic bacteria and worm's ovum, has
Effect prevents it from entering pollution environment and food chain behind growth field with Seedling;Do not use peat and grass simultaneously
Charcoal, economizes on resources, and indirectly avoids the exhaustive exploitation to vegetation for the people, protecting ecology resource.
Prepare the raw material that described substrate also includes following weight portion:Pleurotus eryngii mushroom bran 2-5, sand
4-7, corn straw 3-5.
Described Pleurotus eryngii mushroom bran is 25 for Pleurotus eryngii waste residue adjustment C/N ratio:Obtain through fermentation after 1
's.
After adding mentioned component, each component synergism, effectively strengthen the porosity of substrate, increase
The breathability of big nutrient matrix and water suction, drainage, simultaneously facilitate soil microorganism and develop, change
The impact that kind single-matrix produces to plant in nature in physics and chemistry, improves tomato plant and substrate is fitted
Ying Xing, and then improve emergence rate and the seedling quality of tomato seedling;Avoid and use Vermiculitum in a large number,
Cheap and easy to get, recycling, reduce production cost.
Further improve, prepare described substrate, also to include the crosslinking that parts by weight are 0.5-1 poly-
Dimension ketone and the gelatin of 0.6-1.2.
After adding above-mentioned Crospovidone and the mixture of gelatin, mix with other raw material phases of substrate,
Improve substrate retain water and nutrients performance, buffer day and night temperature, and be beneficial to Soil ventilation, water conservation but
Non-rot root, improves the penetrating situation of soil further.
Improve further, the parts by weight preparing described base starting material are:Decomposed cow dung 3, Fructus Pruni Bao
Mushroom bran 4, Terramycin-type waste water 3.5, perlite 2.5, sand 7, corn straw 4, hay bud
Spore bacillus 0.05, Crospovidone 1, gelatin 0.8.
Preferably, in described substrate, the particle diameter of sand is 0.2-0.4mm.
The present invention provides the fermentation process of Pleurotus eryngii mushroom bran in example described Fructus Lycopersici esculenti substrate, and step is as follows:
1) Pleurotus eryngii waste residue will be dried it will be ground into the fragment of a diameter of 1-3cm, adjust C:N=25:1,
PH value is 6.5-7.5;
2) water content adjusting Pleurotus eryngii waste residue is 50%-60%, then piles centipede space, in 78-85 DEG C
Fermentation 2-3 days, turns over buttress daily;45-65 DEG C ferments 33-46 days, and period turns over and piles up neatly 3-5 time;
De-stacking after fermentation, dry in the sun, separating twice, cross 0.8mm sieve, Pleurotus eryngii mushroom bran of must becoming thoroughly decomposed.
On the other hand, the invention provides the preparation method of described Fructus Lycopersici esculenti substrate, described preparation side
Method is made up of following steps:
1) Pleurotus eryngii mushroom bran, decomposed cow dung and corn straw are pulverized respectively, mix homogeneously with sand
Afterwards, adjust EC value to 0.05-0.2ms/cm through the desalinization of soil by flooding or leaching, be aged in 50-70 DEG C of bar buttress formula
20-40 days, period turned over and piles up neatly 3-6 time, de-stacking after fermentation, and dry in the sun is crushed to 0.3-0.7mm,
Add bacillus subtilises mix homogeneously, obtain biological base;
2) Terramycin-type waste water is dried, be crushed to 0.1-0.4mm, obtain powder stand-by;
3) by step 1) biological base that obtains, step 2) obtain powder, Crospovidone,
Gelatin and perlite mix homogeneously, obtain described tomato seedling substrate.
The each component synergism of tomato seedling substrate of the present invention, makes nursery of the present invention
Substrate contains the organic in a large number and nutrient such as nitrogen, phosphorus, potassium, nutritious and equilibrium;Energy
Enough suppress the harmful substance such as pathogenic bacteria and worm's ovum, effectively prevent it from entering with Seedling and pollute ring behind growth field
Border and food chain;There is higher porosity, good breathability and water suction, drainage, with
When promote soil microorganism develop, improve single-matrix physics and chemistry in nature to plant produce shadow
Ring, improve tomato plant to substrate adaptability;After adding Crospovidone and the mixture of gelatin,
Mix with other raw material phases of substrate, improve the retain water and nutrients performance of substrate, buffer day and night temperature,
And it is beneficial to Soil ventilation, water conservation but non-rot root, improve the penetrating situation of soil further, significantly carry
The emergence rate of high tomato seedling and seedling quality.
On the other hand, tomato seedling substrate of the present invention does not use peat and turf, saves
Resource, avoids the exhaustive exploitation to vegetation for the people, protecting ecology resource indirectly;Avoid simultaneously again
Use Vermiculitum and perlite in a large number, all raw materials are cheap and easy to get, substrate repeats and utilizes, and reduces
Production cost it is achieved that making full use of of resource, has distinct economic and ecological benefits.
