Description
Technical field
The invention belongs to agricultural planting matrix technology fields, and in particular to a kind of solid growth using sawdust manufacture is with gently
Matter Nutrition Soil.
Background technology
Various flowers, seedling, high added value vegetables cultivation field, using three-dimensional greenhouse plantation be most main
The plantation form wanted, this mode are conducive to accurately control planting conditions, improve survival rate and the production of plantation product
Raw rate, shortens implantation time, and efficiently use to space, to improve productivity effect.
Solid growth needs to use plantation frame and cultivation box, by the way that cultivation box to be suspended in plantation frame, and using artificial
The mode that light source carries out cultivation box implants illumination meets the growth demand of plant, and is maximized to the indoor space of temperature
Utilization, middle planting matrix can directly affect the growth of plant in cultivation box, in conventional planting matrix containing a large amount of river sands,
The particle matrixs such as rural area soil, volcanic rock, medical stone, although the planting effect of matrix can be improved, the heavier-weight of matrix,
Larger burden is caused to plantation frame and cultivation box using meeting in spatial planting technology, in some instances it may even be possible to can be by plantation frame be collapsed.
Invention content
In view of the above problems, the purpose of the present invention is to provide a kind of solid growth lightweight nutrition manufactured using sawdust
The nutritional ingredient of soil, the type Light nutritional soil is uniform, is retained good permeability, and planting effect is excellent, and lighter weight, very suitable
Greenhouse solid growth is closed to use.
A kind of solid growth Light nutritional soil manufactured using sawdust, according to mass fraction, the Light nutritional soil at
Divide and contains：27-30 parts of perlite cures 40-60 parts of sawdust, 15-25 parts of pine soil, 26-34 parts of fertile soil, peat soil 14-18
Part, 3-6 parts of a great number of elements composite slow-release fertilizer, 2-4 parts of bacteria remover, 3-4 parts of insecticide, 2-4 parts of lime.
Preferably, according to mass fraction, the ingredient of the type Light nutritional soil contains：28-29 parts of perlite cures sawdust
50-53 parts, 20-22 parts of pine soil, 29-30 parts of fertile soil, 16-17 parts of peat soil, 4-5 parts of a great number of elements composite slow-release fertilizer removes
2-3 parts of microbial inoculum, 3-4 parts of insecticide, 2-3 parts of lime.
Wherein, the preparation method for curing sawdust is：40-60d is stacked by curing room is sent to after sawdust watering wetting, is stacked
Period carries out turning every 13-15d, while continuing to carry out watering wetting to sawdust；Sawdust is sent to after the completion of maturation process
Drying room high temperature drying is sterilized, and the temperature in drying room is 130-150 DEG C, and the drying process time is 3-4h, after the completion of drying
To required curing sawdust.
Preferably, the temperature of curing room is 30-35 DEG C, air humidity 45-60%.
Preferably, the grain size of perlite is 3-4mm.
Preferably, the mass ratio of n-p-k element is 3 in a great number of elements composite slow-release fertilizer:4:3.
Preferably, the intermixture of bacteria remover selection thiophanate methyl, Bravo and carbendazim, the 1 of the mass ratio of three:1:
1, insecticide selects gamma cyhalothrin.
The preparation method of the Light nutritional soil of the present invention includes the following steps：
A, water content humous is adjusted to 40-50% by way of water spray, by the aqueous of peat soil and pine soil
Amount is adjusted to 30-35%.
B, prepare each material composition according to mass fraction, by perlite, curing sawdust, a great number of elements composite slow-release fertilizer and remove
Microbial inoculum is pre-mixed uniformly.
C, the mixture after the dry pack of step B and step A humidifications is added to together in mixing tank, in mixing tank
In be uniformly mixed with the rotating speed of 60-80r/min stirring 10-15min.
D, insecticide is diluted with water according to 300-400 times, then solution is added in mixing tank and continues to stir 3-
5min, while lime being added to the pH value that Nutrition Soil is adjusted in mixing tank, Nutrition Soil is taken out after stirring, is stacked naturally
2-3d obtains required Light nutritional soil；The pH value of the Light nutritional soil is 7.4-8.2.
A kind of solid growth Light nutritional soil manufactured using sawdust provided by the invention, compared with prior art, tool
It has the advantage that：
The type Light nutritional soil has used the particle matrixs such as perlite, pine soil and gas permeability matrix so that the nutrition
Soil is more loose, more ventilative, while it is more uniform to also use nutritional ingredient, the better fertile soil of planting effect and peat soil
Further to improve the Water-saving effect and root guard effect of matrix.
Most of all, in the type planting matrix, also uses and largely cure sawdust, the property of sawdust after maturation process
It is fluffy, it is loose ventilative, and also there is good water imbibition, can be prevented after maturation process sawdust in the soil exothermic oxidation to planting
Object root causes to damage, in addition, the density of the matrix such as curing sawdust, perlite and pine soil is relatively low so that remodeling nutrition
The lighter weight of soil, the matrix for being highly suitable as greenhouse solid growth use.
It also added compound disinfectant, slow-release fertilizer and insecticide in the Nutrition Soil so that the fertilizer efficiency of the Nutrition Soil is more equal
Weighing apparatus is lasting, has good deinsectization bactericidal effect, and the pH value of the matrix is adjusted by lime so that it is more suitable for plant life
It is long.
