Abstract
The invention provides a natural organic fertilizer extracted from seaweed and its preparation method, wherein the organic fertilizer is prepared from sea weed as raw material through the steps of raw material preliminary treatment, leaching, neutralization, concentration, dialysis, and drying.
Description
Technical field
The present invention relates to a kind of natural organic fertilizer material that extracts by marine alga and preparation method thereof.
Background technology
In order to prevent and treat disease and increasing both production and income, chemical fertilizer is used for proportion of crop planting in large quantities.But the life-time service chemical fertilizer can reduce soil quality, destroy ecotope, finally influences production of high-quality farm crop and people's health.Substituting chemical fertilizer with natural organic fertilizer is to improve soil regime, antipollution favourable measure.The fertilizer that uses mainly is by domestic refuse, animal excrement, wheat straw, humic acid, mud etc. are used after simple process at present; Someone studies with seaweed powder and other material mixing as fertilizer, and they are to increasing soil organic matter content, improve the soil property situation certain help is arranged, but then needs long period of time just can show to the effect of plant growth, and effect is not given prominence to; Also there is the people that the activeconstituents of one or two marine algas is added in the composition of fertilizer, though certain effect is arranged, but still fail to make full use of a large amount of activeconstituents that contains in the marine alga.
Summary of the invention
The objective of the invention is to develop a kind of natural organic fertilizer material that extracts by marine alga and preparation method thereof.
The present invention is raw material with the marine alga, by raw materials pretreatment, lixiviate, neutralization, concentrate, technological processs such as dialysis, drying, prepare safety, the non-harmful natural organic fertilizer material that extracts by marine alga fully, thereby realized purpose of the present invention.
So the technical characterictic of the natural organic fertilizer material that the present invention is extracted by marine alga is at the material that is obtained by following preparation method, described preparation method comprises following several steps:
(1), dries or dry, pulverizing in 50～80 ℃ with marine alga raw material shakeout;
(2) above-mentioned seaweed powder is mixed with water, and transfer liquid pH value to 1～2, carry 6～10 hours in 40～50 ℃ of heat with acid;
(3) separate slagging-off, get supernatant liquor with adjusting PH with base value to 4～6;
(4) above-mentioned clear liquid vacuum concentration to solubility is contained thing content admittedly and reach massfraction 3%～10%;
(5) with above-mentioned concentrated solution water dialysis 0.5～24 hour;
(6) get dialyzate concentrate, dry, pulverize, promptly get organic fertilizer of the present invention.
Marine alga raw material described in the described step (1) is sargassun [Sargassum (Turner) C.Agardh], wakame [Undaria pinnatifida (Harvey) Suringar], sea-tangle (Laminaria japonica Areschoug), Sargassum fusiforme [Sargassum fusiforme (Harvey) Setch] etc., is generally commercially available dry product.
Water consumption does not have strict restriction in the described step (2), but can not too much can not be very little, and extraction rate is low very little, too many back concentrates difficulty, be preferably 20～40 times of marine alga raw material dry powder quality, described acid can be hydrochloric acid, sulfuric acid, phosphoric acid, citric acid etc., preferably hydrochloric acid; Separation described in the described step (3) with conventional method for example filter, centrifugal etc., described alkali can be sodium hydroxide, potassium hydroxide, yellow soda ash, salt of wormwood, sodium bicarbonate, saleratus etc., preferably sodium hydroxide; Clear liquid described in the described step (4) preferably is concentrated into solubility and contains thing content admittedly and reach massfraction 5%～8%; Dialysis described in the described step (5) is in order to remove small-molecule substance, preferably to dialyse 10～20 hours.
The preparation method of the natural organic fertilizer material that marine alga of the present invention is extracted comprises above-mentioned (1), (2), (3), (4), (5) and (6) six steps; Experiment condition best in each step is the same.
Organic fertilizer use cost of the present invention is low, solvability good, and plant is had the effect of promotes growth, nutrition, and is harmless to people and animals and physical environment.Plant plant strain growths such as flowers through this organic fertilizer pouring are fast, tall and straight, and the blade face is glossy glossy, and flower is bright-coloured, and prolong flowering period, especially are fit to ornamental plant.The continuous use promptly had significant results in 3 days, and often use is very useful to raising plant disease resistance ability, prolongation life cycle, and the effect that improves edatope is arranged.Water was made into suitable mass concentration (be generally 10～100g/L) and directly water crop, the pouring frequency is with the daily frequency of watering when organic fertilizer of the present invention used.
