Description

A kind of reusable fruit and vegetable seedling medium
Technical field
The present invention relates to a kind of nutrition cultivation matrix of fruit and vegetable, more particularly to a kind of repeatable nursery base for utilizing Matter, belongs to organic cultivation field of fruit and vegetable.
Background technology
Organic mass cultivation refers to use the implantation methods of nature raw material completely during plant growth -- including soil Improvement, fertilising and injurious insect control improve yield so as to improve nursery growth cycle.Without chemical protective agent or other additions Agent, these foods are also referred to as healthy food.
It is that the root system of plant is fixed in the middle of organic matrix, by required for organic substrate supply development of plants Nutrient and moisture, seedling medium are the indispensable raw materials of organic raising seedling, and it is to need the special of configuration according to plant seedling growth development With matrix, formed with one or more organic material mixed configuration.
Existing seedling medium main raw material(s) is sand, rock wool, vermiculite, expansion ceramic, bark, wood sawdust, foamed plastics Deng.Its major defect often contains excessive salinity and calcium carbonate, and structure is unbalanced, and the cultivation initial stage occurs that alkalescence is reacted.
The content of the invention
To solve the above problems, the present invention provides a kind of reusable seedling medium, and the seedling medium can improve plant The yield of thing, shortens plant growing cycle, and can suppress pest and disease damage, and the crop that cultivation is obtained is organic plant.
To achieve the above object, the technical scheme is that being accomplished by the following way:
A kind of reusable fruit and vegetable seedling medium, is made up of following components according to parts by volume:The earth soil 13- 20 parts, peat soil 12-20 parts, microorganism fertilizer 10-30 parts, vermiculite 15-30 parts, compost made of stalks 5-10 parts, perlite 10-30 parts, stove Slag 5-10 parts, coir fibre 10-20 parts, carbonization rice husk 5-10 parts.
Further, the water content of the seedling medium is 35%-40%, and total porosity is 75%-90%, organic content >=60%, total nutrient content is 4%-8%, and capacity is 0.5-0.8g/cm3, gas-water ratio is 1:2-5, EC value≤2.2mS/cm, pH It is 5.6-7.5.
Further, the earth soil is the earth regolith, mellow soil of the thickness in more than 30cm.
Further, the peat soil is organic soil.
Further, the total nutrient is N+P2O5+K2O。
Further, the compost made of stalks is with adding farm manure, the maize straw and farm manure after corn straw smashing Addition mass ratio be 15:1, it is thoroughly mixed fermentation 60 days, N+P in the compost made of stalks2O5+K2O content is about 5.2%.
Further, the farm manure is chicken manure or duck excrement.
Compared with prior art, the beneficial effects of the invention are as follows:
Raw material coir fibre of the invention, slag are all debirs, and quantity is more, and purposes is few, and peat etc. is replaced no with it Reproducible raw material resources, for producing seedling substrate for soilless culture for vegetables, it is possible to reduce environmental pollution, turn waste into wealth, and change evil It is profit;The coir fibre for being used, can increase fiber content in matrix, contribute to microorganism fertilizer to develop breeding;Microorganism fertilizer is adopted With imported raw material, can pre- preventing disease and pest, improve production capacity, shorten the growth cycle of plant;
Coarse size slag, vermiculite, the perlite mix and match of any is made the existing retentiveness of matrix have ventilative again by the present invention Property, change the deficiency of acid-sludge matrix retentiveness difference.Meanwhile, the use of alkalescence carbonization rice husk higher is auxiliary material, not only can be with The acid-base value of buffer matrix, and its potassium content is higher, also abundant trace element, is well suited for the growth hair of vegetable seedling Educate, and it is organic plant to cultivate the crop for obtaining.

The earth soil is the earth regolith, mellow soil of the thickness in more than 30cm in the present embodiment.
Peat soil is organic soil.
Compost made of stalks is that with adding chicken manure after corn straw smashing, the maize straw is 15 with the addition mass ratio of chicken manure: 1, it is thoroughly mixed fermentation 60 days, N+P in compost made of stalks2O5+K2O content is about 5.2%.
Microorganism fertilizer is purchased from Qi Wei companies of the U.S. hundred.
By above-mentioned each component mixed fermentation, stack 15 days, the turning of 1-2 days summer once, once, make by the turning of 6-7 days winter Into seedling medium, above-mentioned seedling medium and generic media raise crop eggplant, capsicum, tomato and cucumber, cultivation side is respectively adopted Method such as following step:
First, milpa protection facility
According to season, the difference of weather conditions, from vinyl house and beam-connected greenhouse protection breeding and seedling nursing with equipment.Winter-Spring nursery is adopted It is incubated with " curtain of two film one " and is covered, from dust-proof without the multi-functional agricultural film of drop;Summer and autumn and autumn and winter nursery use " net of a film one " or " one The net of film two " is covered, and plays windproof, rain-proof, insect prevention and cooling effect.Winter-Spring nursery night can be using ground hot line heating, beam-connected greenhouse Should be equipped with and heat and cooling installation.
2nd, seedbed prepares:
Using ground ridge-up bed:Ridge-up bed 115cm~120cm wide (two length of hole tray), length is not limited, and leveling makes real bed Face, bed surface upper berth layer of plastic film, ridge-up bed surrounding begins to rehearse ditch.Beam-connected greenhouse can configure seedling raising bedstead, and bedstead north and south is placed, Frame 80cm~100cm high, frame 115cm~120cm wide, length is not limited, and 45cm~50cm pavements wide are stayed between bedstead.
Germinating cabinet:
Double-deck brick wall germinating cabinet, brick wall central hollow or filling thermal insulation inorganic material can be built in beam-connected greenhouse, with heating Equipment, it is also possible to which plastic foil is divided into a houselet, there is provided enough temperature conditionss.Configuration nursery plate rail, plate rail 1.8m high is long 2.2m, 1.1m wide, if three layers of dividing plate, bottom 20cm, plate spacing 75cm from the ground.
4th, hole tray specification
The present embodiment selects American hole tray, and external form size is 54.9cm × 27.8cm, mainly uses 3 kinds of Different Nutrition volumes Hole tray, according to selecting suitable seedlings nursing plate the need for different vegetable species and physiology seedling age.
128 hole disks:Aperture is 3.0cm × 3.0cm, it is adaptable to which leaf vegetables, wild cabbage class, short seedling age tomato, capsicum etc. educate Seedling.
72 hole disks:Aperture is 4.0cm × 4.0cm, it is adaptable to the nursery such as solanaceous vegetables, melon, beans.
5th, contrast matrix (embodiment generic media)
Use all nutrition type organic seedling raising matrix.Such as organic reed roots, straw substrate or edible fungi leftovers matrix.
