Description
Technical field
The present invention relates to cultural control insect pest field, it is specially a kind of with prevention and treatment rice disease function formula soil and
Preparation method.
Background technique
In modern agricultural production, pesticide refers to agriculturally for preventing and treating the chemical agent of pest and disease damage and coordinate plant growth,
Epidemic prevention that it is widely used in agriculture forest and husbandry production, environment and domestic hygiene are removed the evil, industrial goods it is mould proof with it is mothproof etc..Obviously, pesticide
There is irreplaceable role in modern agricultural production.
Traditional pesticide in use, has the drawback that (1) is easy to change the original composed structure of soil, unfavorable
In the friendly sustainable development of environment；(2) bad dispersibility is unfavorable for the absorption of plant；(3) it has a single function, peasant household is caused to need
Apply various medicaments.
For this purpose, providing that a kind of formulation rate is few and new soil formula that pest control effect is good is for assisting plantation farming
Object is technical staff's urgent problem to be solved.
Summary of the invention
The present invention provides a kind of formula soil and preparation method thereof with prevention and treatment rice disease function, the formula soil
Has the advantages that Shaoshi multiple-effect.
To achieve the above object, the invention provides the following technical scheme:
A kind of formula soil with prevention and treatment rice disease function, based on parts by weight, including 25~35 parts of plant charcoal, it sticks
35~60 parts of soil, 10~20 parts of organic fertilizer and 2~8 parts of sustained release agent.
Preferably, the plant charcoal is selected from cymose buckwheat rhizome stem charcoal, cocoanut charcoal, China tree charcoal, in cassava charcoal and corncob charcoal
At least one.
Preferably, organic fertilizer includes bio-fertilizer and is produced by isolated secondary metabolism in fungal secretion
Object.
Preferably, the fungi of isolated secondary metabolite is selected from Armillaria luteo-virens, Russula vivesscens (Schaeff.) Franch and mangrove
At least one of rhizosphere soil fungi.
Preferably, the bio-fertilizer is selected from least one of cow dung, pig manure and chicken manure.
Preferably, the sustained release agent is selected from carboxymethyl chitosan, CoFe2O4Graphene nanocomposite material and diatom
At least one of soil.
Preferably, the formula soil is based on parts by weight, including 35~60 parts of clay, and 5~15 parts of cymose buckwheat rhizome stem charcoal, coconut palm
3~8 parts of sub- charcoal, 5~10 parts of China tree charcoal, 2~8 parts of cassava charcoal, 3~12 parts of corncob charcoal, Armillaria luteo-virens secondary metabolite 5
~7 parts, 3~6 parts of Russula vivesscens (Schaeff.) Franch secondary metabolite, 5~12 parts of mangrove plant rhizosphere soil fungi secondary metabolite, cow dung 5
~15 parts, 4~9 parts of chicken manure and 3~6 parts of carboxymethyl chitosan.
Preferably, the formula soil is based on parts by weight, including 45 parts of clay, and 10 parts of cymose buckwheat rhizome stem charcoal, cocoanut charcoal 6
Part, 7 parts of China tree charcoal, 5 parts of cassava charcoal, 8 parts of corncob charcoal, 6 parts of Armillaria luteo-virens secondary metabolite, Russula vivesscens (Schaeff.) Franch secondary metabolism produces
5 parts of object, 8 parts of mangrove plant rhizosphere soil fungi secondary metabolite, 12 parts of cow dung, 7 parts of chicken manure and carboxymethyl chitosan 4
Part.
Wherein, cymose buckwheat rhizome stem charcoal, China tree charcoal, cassava charcoal have bacteria resistance function, can reduce plant root disease microorganism
Breed breeding.Meanwhile by the way that cocoanut charcoal is added in plant charcoal, its mixed air penetrability of various plants charcoal can be increased, can be increased
The entrance of oxygen prevents rice from rotten illness occur.Meanwhile corncob charcoal can provide sufficient magnesium member for rice plant
Element promotes rice plant to carry out photosynthesis, the yield of paddy can be improved.
Also, Armillaria luteo-virens secondary metabolite, Russula vivesscens (Schaeff.) Franch secondary metabolite, mangrove plant rhizosphere soil fungi time
The special terpene substances contained, after being absorbed by rice plant, are storable in the vacuole of cell in raw metabolite, not only to edible
The body of person is harmless, and long-time service can reduce the probability for suffering from inflammation, influenza.Meanwhile terpene substances are stored in vacuole, can make water
Rice plants give out certain " smell ", drive away the natural enemy of rice, prevent pest from biting Rice Leaf.
The present invention also provides a kind of preparation method of formula soil with prevention and treatment rice disease function, the preparation methods
Include the following steps:
(1) plant charcoal for accurately weighing preset weight number, pulverizes, and crosses 200 meshes, obtains plant charcoal mixed-powder.
(2) plant charcoal mixed-powder is uniformly mixed with clay, obtains thick soil.
(3) secondary metabolite of preset weight number fungi is taken to be uniformly mixed with sustained release agent, and in 35~40 DEG C of temperature
It is stirred continuously 60~90min of stir-frying under the conditions of degree, obtains embedded object.The step is the process of chelating, can make carboxymethyl chitosan
Small-molecule substance (secondary metabolite) embedding is got up, sustained release is played the role of.Meanwhile carboxymethyl chitosan sugar also has itself
There is fungistatic effect, rice plant illness can be effectively prevent.
Wherein, Armillaria luteo-virens secondary metabolite the preparation method comprises the following steps:
A, Armillaria luteo-virens are inoculated in LB culture medium and cultivate 45~60 days, filter to the secretion of Armillaria luteo-virens
Processing, obtains filtrate.
B, filtrate is mutually extracted through petroleum ether, and liquid separation after extraction obtains petroleum ether phase.
C, ethyl acetate is added in petroleum ether phase, liquid separation after extraction obtains ethyl acetate phase.
D, ethyl acetate phase is rotated to medicinal extract shape to get Armillaria luteo-virens secondary metabolite is arrived.
The preparation method of Russula vivesscens (Schaeff.) Franch secondary metabolite is same as above.
Mangrove plant rhizosphere soil fungi secondary metabolite is same as above.
(4) obtained embedded object is uniformly mixed with thick soil, the formula soil can be obtained.
Preferably, the temperature for stirring stir-frying is 37 DEG C in step (3), the time for stirring stir-frying is 80min.
The invention has the benefit that
Plant charcoal selected by the present invention has bacteria resistance function, can reduce the growth breeding of plant root disease microorganism.
Meanwhile in added Activities of Some Plants charcoal, sufficient magnesium elements can be provided for rice plant, and cooperate organic fertilizer, can promote
Rice plant carries out photosynthesis, and the yield of paddy can be improved.Due to being also added with sustained release agent in the formula soil, suppression may make
Bacterium growth-promoting effect is more preferably lasting, is more suitable the growth cycle of rice.
