Description
Technical field
The invention belongs to organic nutrient soil technical field, and in particular to a kind of organic battalion of the composite modified sulfate of fermentation of seaweed
Support the preparation method of soil.
Background technology
Marine alga is the original producer of marine organisms, with powerful adsorption capacity, can concentrate equivalent to itself 44
Equilibrium is extremely enriched in ten thousand times of ocean material, nutrition.Contain protein, polysaccharide, food fiber, vitamin, inorganic member in marine alga
The materials such as element, amino acid, aliphatic acid, are all widely used in the field such as industry, agricultural, medicine, beauty, also with very high
Food therapy value.
Chitin is the natural macromolecular material as obtained from shrimp, crab or insect shell pass through soda acid working process, and shell
Glycan is the derivative of chitin, therefore, and preparing chitosan-based compound bio using accessory substance-shrimp shell of cray adsorbs
Material, can be achieved to turn waste into wealth, twice laid, embody the theory of recycling economy.
In recent years, with the adjustment of agricultural planting structure, agriculture multiple crop index is improved constantly, the increase of crop yield,
China's agricultural infrastructure condition, crop allocation, planting system, fertilization structure, farming etc. there occurs larger change, soil nutrient
Larger change also occurs with farmland quality.Because soil bottom is unclear, blindly fertilising causes crop yield and quality to reduce, and applies
Fertile decline in benefits, farmland quality is degenerated, and corps diseases generally occur, and a large amount of N and P losses cause agricultural non-point source pollution to aggravate,
Some areas body eutrophication degree of progress speed, the deterioration of the ecological environment, overall agricultural productivity reduction seriously governs agriculture life
The sustainable development and raising of production.
The content of the invention
The present invention provides a kind of preparation method of the composite modified sulfate organic nutrient soil of fermentation of seaweed, prepared by the present invention
Product can greatly increase production efficiency, and can kill harmful microorganism in raw material, disease pest ovum etc., while having retaining
Water retention, it is biodegradable.
The present invention is achieved by the following technical solutions：
A kind of preparation method of the composite modified sulfate organic nutrient soil of fermentation of seaweed, it is characterised in that comprise the following steps：
（1）Marine alga is degraded
After 30-40 parts by weight marine alga is crushed, the sodium hydroxide for adding 10-20 parts by weight 10-40% carries out after boiling 20-30 points
Zhong Hou, after 30-50 DEG C of reheating is kept for 0.5-3 hours, is cooled to after room temperature, in the hydrochloric acid progress for then adding appropriate 10-40%
After extremely neutrality, filter residue is collected by filtration, it is stand-by；
（2）Modified kraft
10-15 parts by weight shrimp shell meals are dissolved in 50-100 parts by weight 2wt% acetic acid solution, addition is dissolved with 1-3 parts by weight
The acetone soln of maleic anhydride and 1-5 parts by weight of acrylic acid, 5-15 parts sulfuric acid salt is added to the water, and controls the solution ph to be
4.5-5.5, adds 2-5 parts by weight of silica superfine powders, stirs 30-50 minutes, and regulation solution ph is 10-12, crosses and is filtered dry
After dry 6-12 hours, powdery is ground to form by grinder, modified barium sulphate is obtained, it is stand-by；
（3）Ferment in greenhouse
To step（1）Gains are added after 2-10 parts by weight of bentonite and strong stirring make it well mixed, then add 1-3 weights
Measure part activated carbon and step（2）Gains, mix rear greenhouse thoroughly and ferment 5-7 days, fermentation temperature is controlled at 55-65 DEG C, fermentation is completed
Afterwards, it is stand-by after being sterilized；
（4）The preparation of Nutrition Soil
By step（3）The tunning of gained with, 5-10 parts by weight calcium superphosphate, 1-5 parts by weight expanded vermiculite, 1-5 parts by weight
Expanded perlite, 10-25 parts by weight water input into mixer stirring, are transported in twin rollers and are squeezed into after stirring
Grain, low temperature sterilization and drying are carried out by particle, are packed after cooling, both obtain the composite modified sulfate organic nutrient soil of fermentation of seaweed.
Described sulfate is selected from：Potassium sulfate, ammonium sulfate, calcium sulfate, magnesium sulfate, one kind or many of zinc sulfate and copper sulphate
Kind, described regulation pH is the hydrochloric acid or sodium hydroxide solution using 20-40%.
The step（3）It is temperature control at 80-130 DEG C to sterilize, and the high temperature that fermentation raw material is carried out 10-60 minutes is gone out
Bacterium.
Described fermentation is fermented using taper, is banked up and is shaped as taper, and time interval is to be stirred once for 2-3 days.
The step（4）Sterilize as in swinging sterilization stove, temperature control is at 60-100 DEG C, and time control is in 30-90
Minute.
It is an advantage of the invention that：
（1）The present invention adds sodium hydroxide after being crushed first with marine alga and carried out after boiling, and hydrochloric acid is used after insulation a period of time
Filtered after being neutralized, then shrimp shell meal is dissolved in acetic acid and added after maleic anhydride and acrylic acid reacted, by sulfuric acid
Salt is scattered with after regulation pH dispersed silicon dioxide superfine powders in the solution, obtaining modified barium sulphate, is then carried out with marine alga filter residue etc.
It is stirred after mixing extruding sterilization treatment and was both obtained with other dispensings after greenhouse fermentation, marine alga is steamed in sodium hydroxide solution
After boiling, accelerating the chitin in the degraded of marine alga, filter residue and bentonite, shell powder can be connect with maleic anhydride and acrylic acid
It is acylated after chitin grafting in branch, shrimp shell meal, gel can be formed in the basic conditions is wrapped in sulfate and silica
The surface of superfine powder, forms stable microcapsule structure, and the Active sites on silicon dioxide ultrafine powder surface are more, can be with gathering
Compound is combined closely, and forms stable microcapsule structure, promotes cross-linked structure, slowly release can kill harmful micro- life to sulfate
Thing, disease pest ovum, and marine alga degraded filter residue are well mixed the quality and rotten degree height of the tunning of after fermentation, rich in crop
The nutrients such as the nitrogen, phosphorus, the potassium that need, can greatly increase the content of organic matter, after extruding, form the particle of an entirety,
Keep the nutritional ingredient in Nutrition Soil not to be lost in, be conducive to nitrogen, phosphorus, potassium, trace element and the organic matter nutrients in Nutrition Soil
Matter slowly discharges, it is ensured that the nutrition required for crop growth, so makes heavy metal ion when entering in crop body, is collected
In in the root of crop and stem, can be degraded by biology, can strengthen the water holding capacity of soil, reduction soil moisture
Evaporation and loss.
（2）Product prepared by the present invention can greatly increase production efficiency, and can kill harmful micro- life in raw material
Thing, disease pest ovum etc., while there is retaining water retention, it is biodegradable.
