Description
Technical field
The present invention relates to agricultural technology fields, more particularly to a kind of to utilize the control of multifunctional natural biostatic agent
The method of water silk floss in rice field processed.
Background technique
For many years, in the rice cultivation process, the dosage of chemical fertilizer is being continuously increased, and especially a large amount of of phosphate fertilizer make
With so that the Water Eutrophication degree in rice field is on the rise, leading to the large area deposition of rice field water silk floss, affect the good of rice
It is quite long and solid.Simultaneously because the use of chemical fertilizer and pesticide, the resistance of rice weakens, and the generation of pest and disease damage is increasingly
Seriously, rice quality is caused to decline；These factors seriously constrain the Green Sustainable of China's rice industry.With multiple
The use of the green agriculture input (pesticide, fertilizer) of effect is the inevitable choice of agriculture cycle development.
Stalk resource is the most abundant resource of reserves in the world, the comprehensive utilization of agricultural crop straw more and more attention has been paid to,
Charcoal, the multi-products such as vinegar liquid and biological flue gas can be obtained in stalk after pyrolysis.Pile up like a mountain for house refuse, affects cities and towns
Change construction and beautiful rural construction, is raw material using fresh plant waste, handling through microbial fermentation can be obtained fermentation liquid
And fermentation solid.The use of environmentally protective input is to promote the key point of its sustainable development during Rice Cropping.
Therefore it provides a kind of method using multifunctional natural biostatic agent control rice field water silk floss is those skilled in the art
The problem of member's urgent need to resolve.
Summary of the invention
In view of this, utilizing stalk vinegar the present invention provides a kind of method using biostatic agent control rice field water silk floss
Liquid and fresh plant fermentation liquid can not only realize that the high value of stalk utilizes as water silk floss inhibitor, while can push rubbish point
Class and decrement, moreover it is possible to promote greenization, the environmental protection of Rice Cropping.
To achieve the goals above, the present invention adopts the following technical scheme:
A method of it is continuous using biostatic agent control rice field water, the specific steps are as follows:
(1) crops stalk crushing is dried, is pyrolyzed after compression in pyrolysis oven, cooling collection pyrolysis liquids are quiet
It only places 20-30 days, takes middle layer, obtain stalk vinegar liquid；
(2) plant waste and the buckwheat of crushing are mixed by the weight ratio of 8-9:1, obtains blends of plant materials；
(3) blends of plant materials and molasses and water obtained step (2) is mixed in the ratio of 3:1:10, is sufficiently stirred
It mixes, after aerobic fermentation 30 days, carries out anaerobic fermentation being fully sealed 60 days, fermentation is completed to be separated by solid-liquid separation, and takes supernatant, obtains
Plant fermented liquid；
(4) plant fermented liquid that stalk vinegar liquid and step (3) that step (1) obtains obtain is filled according to the ratio of 1:1-5
Divide mixing, the water that 5-8 times of volume is added is uniformly mixed, and obtains biostatic agent, is sealed cool place and is kept in dark place；
(5) biostatic agent that step (4) obtain is diluted to 100-200 times, Irrigated paddy field 2-3 times avoids rainy days
It irrigates.
Further, step (1) specific steps for crushing drying are as follows: by crops stalk crushing to 1-2 centimetres, 100-
105 DEG C dry 4 hours.
Further, step (1) pyrolysis temperature is 400-500 DEG C, pyrolysis time 3-5h.
Further, step (2) described plant waste includes a variety of fresh samples such as dish leaf, pericarp.
Further, step (2) described plant waste is switched to 1-2 centimetres, and the buckwheat crushed 50 meshes.
Further, step (3) described separation of solid and liquid can be using modes such as solid-liquid separating machine, centrifuge separation or filterings.
Further, application of the stalk vinegar liquid in control rice field water silk floss.
Further, application of the plant fermented liquid in control rice field water silk floss
It can be seen via above technical scheme that compared with prior art, utilizing biology suppression the present disclosure provides a kind of
The method of preparation control rice field water silk floss can not only be realized using stalk vinegar liquid and fresh plant fermentation liquid as water silk floss inhibitor
The high value of stalk utilizes, while can push garbage classification and decrement, moreover it is possible to promote greenization, the environmental protection of Rice Cropping；This
The water silk floss inhibitor of invention has the characteristics that natural, environmental protection, production are simple；Acids, alcohols, phenols, enzyme are included in inhibitor
Many kinds of substance and microorganism are waited, not only has the characteristics that inhibit the growth of water silk floss, while there is disease-resistant, expelling parasite, growth promotion, water quality is net
The multi-efficiency of change.Stalk vinegar liquid of the invention and plant fermented liquid are used alone, and can also achieve the effect that control water silk floss.
