Description
Technical field
The present invention relates to technical field of agricultural cultivation, more particularly to a kind of wormcast seedling medium and preparation method thereof.
Background technology
Nursery at present mostly using non-renewable, non-degradable material the simple matrix of compounding such as peat, cotton rock, on the one hand by
Without specific matrix parameter and standard in production, the physicochemical character of seedling medium is poor, nutritional ingredient lack, cause nursery into
Motility rate is relatively low；The non-renewable, non-degradable materials such as another aspect peat, cotton rock are there are Resource exhaustion and cause environmental pollution
Problem, therefore it is extremely urgent to study a kind of excellent seedling medium of physicochemical property.
The content of the invention
The embodiment of the present invention provides a kind of wormcast seedling medium and preparation method thereof, a large amount of to solve existing seedling medium
Environmental pollution is caused using non-renewable, non-degradable materials such as peat, cotton rocks and there are problems that Resource exhaustion risk.
The present invention provides a kind of wormcast seedling medium, and the seedling medium is according to mass percent by following components group
Into：Wormcast 50%-60%, charcoal 10%-30%, ardealite 10%-20%, vermiculite 10%-20%, the wormcast are
Earthworm eats and digests the excrement discharged after earthworm feedstuff made of the stalk and cow dung.
In the wormcast seedling medium of the present invention, the earthworm feedstuff is 1 by mass percent:9 stalk and cow dung
It is mixed.
The present invention also provides a kind of wormcast seedling medium preparation methods, include the following steps：
Step 1：Process the earthworm feedstuff made of stalk and cow dung；
Step 2：Earthworm feedstuff feeding earthworm made of step 1 is used to prepare good wormcast；
Step 3：After earthworm is separated with wormcast, it is utilized respectively；
Step 4：Take by mass percentage wormcast 50%-60%, charcoal 10%-30%, ardealite 10%-20%,
Vermiculite 10%-20% is mixed and made into seedling medium.
Processing earthworm feedstuff in the wormcast seedling medium preparation method of the present invention, in the step 1 is specially：
Step 1.1：Stalk is ground into the particle that length is 5-8mm；
Step 1.2：By the stalk cut by 1:9 mass ratio stirs evenly with cow dung and earthworm feedstuff is made.
In the wormcast seedling medium preparation method of the present invention, the step 2 is specially：
Earthworm is fed with earthworm feedstuff 1.5-2 months, is treated that cow dung stench peculiar smell disappears, is just generated excellent earthworm at this time
Excrement.
In the wormcast seedling medium preparation method of the present invention, the step 4 is specially：
The wormcast of production is paved into thin layer progress natural drying to moisture and is down to less than 30%, takes earthworm by mass percentage
Earthworm excrement 50%-60%, charcoal 10%-30%, ardealite 10%-20%, vermiculite 10%-20% are stirred and evenly mixed and nursery base are made
Matter.
The beneficial effects of the present invention are：A kind of wormcast seedling medium of the present invention, using wormcast as main material
Material, stalk therein, cow dung, charcoal, ardealite are the regeneration of discarded object, not only turn waste into wealth but also solve to burn because of stalk
The environmental pollutions such as the atmosphere polluting problem brought and cow dung are burnt, this not only increases economic benefit, while has larger
Ecological benefits.Stalk can increase organic matter and aeration status in feeding earthworm；Biological carbon contains organic matter, carbon, potassium phosphorus,
Calcium and trace element, at the same permeability also preferably can loose texture, improve structure；Ardealite can also change structure, increase calcareous
And a small amount of phosphorus content；Vermiculite mainly increases permeability and plays improvement structure, and whole mellowness is ventilated, favourable germination, seedling
Seedling is grown.
With cow dung and stalk feeding earthworm, the wormcast of production is a kind of natural organic fertilizer, rich in nitrogen, phosphorus, potassium, is had
Machine matter and amino acid, it has tiny clean, sanitary, free from extraneous odour, particle, water imbibition, a water-retaining property energy consumption, and ventilating air permeability is strong
Advantage, wormcast can promote root system of plant to develop, and seed is promoted to sprout and yield positive results, and resist with enhancing seed and seedling
Sick antibacterial functions, additionally it is possible to improve the resistance of reverse of crop seedling, using seedling medium of the present invention carry out eggplant, capsicum,
The nursery such as tomato, rice, emergence rate, seedling growth are significantly better than market conventional substrate.
Description of the drawings
Fig. 1 is a kind of wormcast seedling medium preparation method flow chart of the present invention.
Specific embodiment
The present invention provides a kind of wormcast seedling mediums, and the seedling medium is according to mass percent by following components group
Into：Wormcast 50%-60%, charcoal 10%-30%, ardealite 10%-20%, vermiculite 10%-20%, the wormcast are
Earthworm eats and digests the excrement discharged after earthworm feedstuff made of the stalk and cow dung.
Wherein, earthworm feedstuff is 1 by mass percent:9 stalk and cow dung are mixed.
The present invention also provides a kind of wormcast seedling medium preparation methods, include the following steps：
Step 1：Process the earthworm feedstuff made of stalk and cow dung；
When it is implemented, stalk is ground into the particle that length is 5-8mm, by the stalk cut by 1:9 mass ratio with
Cow dung, which stirs evenly, is made earthworm feedstuff.
Step 2：Earthworm feedstuff feeding earthworm made of step 1 is used to prepare good wormcast；
When it is implemented, being fed with earthworm 1.5-2 months with earthworm feedstuff, treat that cow dung stench peculiar smell disappears, just generate at this time
Excellent wormcast.
Step 3：After earthworm is separated with wormcast, it is utilized respectively；
Step 4：Take by mass percentage wormcast 50%-60%, charcoal 10%-30%, ardealite 10%-20%,
Vermiculite 10%-20% is mixed and made into seedling medium.
Less than 30% is down to when it is implemented, the wormcast of production first is paved into thin layer and carries out natural drying to moisture, then
