Description
Technical field
The invention belongs to technical field of fertilizers, and in particular to a kind of vegetables sustained release liquid fertilizer and preparation method thereof.
Background technique
Vegetables occupy an important position in human lives, and status is only second to cereal crops.Currently, scale vegetable is planted
It quickly grows, but fertilizer practice falls behind relatively, vegetable grower's fertilising is blindly applied by rule of thumb completely, and fertilizer waste is serious, while can draw
The problems such as playing soil acidification, secondary salinization, high groundwater azotate pollution and nitrate salts content of vegetable.Wherein, tubers vegetable
Dish is a major class for vegetables.Potato is planted as a kind of most important rhizome vegetable in northern China large area, with
The starting of potato staple food grainization strategy, cultivated area is by further expansion.
Vegetable castoff refer to leaf vegetables during greenhouse or Production of Large Fields, solanaceous vegetables, melon and beans seedling, rattan, it is climing,
The waste or vegetable distribution that root, stem and leaf generate vegetables carry, it is discarded surplus to arrange the various victuals that link generates
Excess.Fast-developing vegetables industry brings a large amount of vegetable castoffs, and " waste dish is tired " becomes one that city currently faces
Worried problem.Cattle and sheep can not digest the waste dish of these substantial amounts, and useless dish rotten leaf is directly gone back to field as fertilizer and needs one again
A slow putrefaction process, and this putrefaction process generates stench and a large amount of germs, returns in field to the yield of vegetables, product
Matter can all have an impact.
Summary of the invention
The present invention proposes that a kind of vegetables sustained release liquid fertilizer, the sustained release liquid fertilizer not only solve the benefit of vegetable castoff
With problem, moreover it is possible to improve utilization rate of fertilizer, also reduce the generation of pest and disease damage.
The technical scheme of the present invention is realized as follows:
A kind of vegetables sustained release liquid fertilizer, is prepared from the following raw materials in parts by weight:
26~32 parts of vegetable castoff extract, 17~23 parts of Cordyceps militaris solid medium residue treatment object, polyvinyl alcohol 7
~9 parts, 2~3 parts of 4~6 parts of sprouted unpolished rice, polyvinylpyrrolidone, 0.6~1.3 part of the alcohol of C2-C4, seaweed for boiling processing
6~13 parts and 65~75 parts of water of sugar；The preparation method of the vegetable castoff extract is to be added after smashing vegetable castoff
Into dilution biogas slurry, decomposed 15~20 days with corn stover.
Preferably, the extension rate of the dilution biogas slurry is 9 times, and the dilution biogas slurry refers to anaerobic fermentation biogas slurry and water
It is mixed according to 1:8.
Preferably, the Cordyceps militaris solid medium residue treatment object is to use after smashing Cordyceps militaris solid culture based draff
Cellulase is digested to obtain with polysaccharase.
Preferably, the alcohol of the C2-C4 is ethyl alcohol, propyl alcohol or 1,3-BDO.
It is a further object to provide a kind of vegetables preparation methods of sustained release liquid fertilizer, including following step
It is rapid:
1) by polyvinyl alcohol, boil the sprouted unpolished rice of processing and water is stirred at 90 DEG C~95 DEG C and solution is made, obtain
Polyvinyl alcohol liquid；
2) polyvinyl alcohol liquid is cooled to 65~70 DEG C, then adds polyvinylpyrrolidone and trehalose stirs
Uniformly, it then is cooled to room temperature and joins remaining material and stir evenly.
Beneficial effects of the present invention:
1) vegetables of the invention select vegetable castoff extract and Cordyceps militaris solid medium residual with sustained release liquid fertilizer
Vegetable castoff extract is prepared as primary raw material, by the decomposed fermentation of dilution biogas slurry in Slag treatment object, passes through cellulose
Enzyme and polysaccharase are digested to obtain Cordyceps militaris solid medium residue treatment object, and amino abundant can be provided for vegetable growth
Acid, polysaccharide and biological enzyme etc., convenient for the absorption of vegetables, can be used as foliar fertilizer and apply fertilizer.
2) vegetables of the invention are with sustained release liquid fertilizer using polyvinyl alcohol, the sprouted unpolished rice and polyethylene pyrrole that boil processing
Pyrrolidone carries out coated slow-release to primary raw material, forms reticular structure, can effectively adsorb the active constituent in primary raw material.Fertilizer
Also added in material trehalose its can play the role of to the water tariff collection of root system and blade face cell it is good, to promote fertilizer living
Property ingredient is in transmission and absorption wherein.
