Description

The sweetened liquid fertilizer method of preparation and use of marine alga-earthworm hydrolyzate efficient bio-active
Technical field
The present invention relates to technical field of agricultural fertilizers, more particularly to a kind of marine alga-earthworm hydrolyzate efficient bio-active increases The method of preparation and use of sweet liquid fertilizer.
Background technology
Marine alga fertilizer is the bio-feritlizer being processed into through science using sea-plant marine alga as primary raw material, mainly into Point be extracted from marine alga be conducive to the natural bioactivity substance of growth and development of plants and marine alga to be absorbed from ocean and richness The mineral nutrient element of collection in vivo, including algal polysaccharides, phenols poly-compounds, mannitol, glycine betaine, plant growth regulating Material and nitrogen, phosphorus, potassium, iron, boron, molybdenum, iodine etc. are micro.Therefore, marine alga fertilizer have it is nutritious, active it is strong, easily absorbed, can The features such as improved soil, safety nuisance free.Because with above-mentioned a series of advantage, marine alga fertilizer is increasingly becoming people competitively The focus of research and development.But, although existing marine alga fertilizer rich in nutrition content, active component is poor, function is single, application field Still there is certain limitation.
Amino acid is the accelerator of synzyme and catalyst in plant, and plant metabolism is played an important role.Grind Study carefully discovery, amino acid is acted in growing process three:(1)The supplement source of organic nitrogen nutrient;(2)The chela of metal ion Mixture, amino acid has complexing(Chelating)The effect of metal ion, easily by the moderate-element and trace element needed for plant(Such as Calcium, magnesium, manganese, zinc, copper, molybdenum, boron, selenium etc.)It is carried in plant, improves utilization rate of the plant to various nutrients;(3)Enzymatic enters Agent.The raw material used in production amino acid fertilizer is mainly hair, cotton dregs etc. at present, the hydrolysate of above-mentioned albumen, except containing Amino acid, but other active components lack.
Also there are other active fertilizer of increase, a kind of earthworm as disclosed in Application No. 201410178045.8 in the prior art Earthworm hydrolysate and rare earth composite reactive blade face liquid fertilizer, its method of preparation and use, it uses agricultural rare-earth and earthworm hydrating solution It is used as primary raw material, although so that the other active components in addition to amino acid are improved, but is due to it in preparation process Directly it is hydrolyzed after earthworm is homogenized, causes the amino acid concentration of hydrolysis degree and release still not ideal enough.
The content of the invention
In view of the defects and deficiencies of the prior art, the present invention intends to provide a kind of marine alga-earthworm hydrolyzate is efficient The method of preparation and use of the sweetened liquid fertilizer of bioactivity.
To achieve the above object, the present invention uses following technical scheme.
The sweetened liquid fertilizer preparation method of marine alga-earthworm hydrolyzate efficient bio-active, comprises the following steps:
(1)The preparation of earthworm hydrolyzate:
Fresh and alive earthworm is cleaned up, after freezing, pulp is crushed, addition is 1.5~2.0 with earthworm weight ratio:1 water is mixed It is even, its pH value is then adjusted with citrate solution to 4.5~6.0,1000U/g acid protease is added, in 28~35 It is hydrolyzed at a temperature of DEG C, the earthworm liquid after hydrolysis is separated by filtration, sterilized, earthworm is made by hydrolysis time 12~24 hours afterwards Earthworm hydrolyzate, it is stand-by;
(2)The preparation of liquid seaweed extract:
The complex enzyme and 2 ‰ complex micro organism fungicide of addition 2 ‰ in liquid are crushed in marine alga, aerobic hair is carried out in fermentation tank Ferment, to control fermentation temperature be 30~50 DEG C, pH is 6~7, and fermentation time 3~7 days is filtered, sterilized, marine alga is made afterwards Liquid fertilizer, it is stand-by;
(3)It is mixed with:
By above-mentioned steps(1)In obtained earthworm hydrolyzate and step(2)In obtained liquid seaweed extract respectively using volume ratio as 2:3 Ratio be transferred in reactor, under normal temperature react 1.5~3 hours, afterwards release, stand, detection, it is filling, be made liquid fertilizer into Product.
Further, step(2)Described in complex enzyme be cellulase and pectase mixture.
Further, step(2)Described in complex micro organism fungicide be the mixed of bacillus subtilis and bacillus licheniformis Compound.
The sweetened liquid fertilizer application method of marine alga-earthworm hydrolyzate efficient bio-active:
If subject is legume crop, suitable whole growth period uses, using when, liquid fertilizer finished product is diluted 600~1000 Times, interval is repeated once for 10~20 days, at least 2~3 times;
If subject is cereal crops, suitable whole growth period uses, using when, liquid fertilizer finished product is diluted 600~1000 Times, interval is repeated once for 10~20 days, at least 2~3 times;
