Abstract
The present invention relates to a method for preparing a red algae polyphenol stress-resisting growth regulator. Abundant red algae resources in China are fully utilized, and the red algae polyphenol stress-resisting growth regulator is prepared by means of the following basic technological processes: cleaning red algae with seawater, cutting up the red algae, soaking the cut red algae in an alcohol solution for 1 to 2 days, filtering so as to obtain mother liquor, evaporating at vacuum and concentrating. Products of the present invention can promote the absorption of moisture and nutrients of crops, can promote the development of root systems and can enhance drought resistance and disease resistance so as to improve the yield and quality of crops. The present invention is widely used for soaking seeds of crops and vegetables, spraying and pouring roots, and yield can be increased by 10 to 20%. With the advantages of simple process, convenient use and low price, the red algae polyphenol stress-resisting growth regulator is a natural effective stress-resisting plant growth regulator which is expected for a long time by people.
Description
The present invention relates to a kind of preparation method of resisting growth regulator of red alga polyphenols
The flourishing countries of marine alga chemical research such as the existing U.S., Britain utilize marine alga unique biological chemical constitution to prepare seaweed fertilizer, make the mainstay industry that seaweed fertilizer is produced has become seaweed industry, and usefulness is peculiar obviously, makes its product application very extensive.But still be not reported so far to utilizing the resisting growth regulator of red alga polyphenols that contains rich functions activeconstituents polyphenolic compound comparatively in the marine alga and using.As the China of the large agricultural country of one of four abundant powers of world's marine algae resource, the large-scale economical alga class of existing spontaneous growth has the marine alga of propagating artificially again, develops new product and will produce wide prospect to China's agricultural development.
What the objective of the invention is to make full use of China enriches the red algae resource, the production method of the active high-effect biological organic fertilizer of a kind of pure natural type---the preparation method of resisting growth regulator of red alga polyphenols is provided, to improve the quality and yield of crop, the further expansion of reduction chemical fertilizer.
The elite of product enrichment red algae of the present invention, the concentration height, fertilizer efficiency is long, can replenish plant fast the edge of nutritive ingredient is lacked, stimulates the absorption of crop to nitrogen, phosphorus, potassium, promote root system development, improve the effect of root system vigor, make crop absorb more moisture and nutrient, strengthen its drought-resistant ability; Can improve plurality of enzymes activity and chlorophyll content in the plant materials again, make metabolism vigorous, photosynthesis is strengthened, and sugar part and dry-matter increase, thereby have improved the yield and quality of crop; Also have anti-oxidant activity and the biological activity of resisting microorganism, improve the crop disease-resistant ability.Its technology is simple, and is easy to use, cheap.
Accompanying drawing is a process flow sheet of the present invention.
Preparation method of the present invention is as follows:
(1), red algae is clean with seawater flushing, and shred with shredding machine;
(2), the red algae of chopping is used the alcohol immersion (1-2 days) of 70-80%;
(3), filter soak solution, filter residue soaked 1 day with the ethanol secondary, filter residue discards.
(4), secondary filtration liquid is merged as mother liquor, carry out vacuum-evaporation at 40-60 ℃ then and be concentrated into finite concentration or volume.
Above-mentioned red algae has aquatic foods, thousand branch, selects for use bright product to be advisable.Should be good as the red algae raw material in addition, as multitube algae, Rhodomela confervoides and concave crown algae etc. with the kind that is rich in polyphenol.
Above-mentioned soaking solution ethanol should select in the 70-80% scope, and the weight ratio of alcohol immersion solution and red algae raw material is about 2: 1.
Being widely used on agricultural soaked seed the concentrated solution dilution of resisting growth regulator of red alga polyphenols for 200-300 times to farm crop and vegetables; Spray, irritate root dilution 400-500 doubly.Its effect, increasing crop yield 12-18%; Vegetables volume increase 15-25%.Main crop varieties comprises: farm crop wheat, corn, beans, paddy rice etc.; Greengrocery such as rape, spinach, Chinese cabbage, cucumber, tomato, radish, celery, potato etc.
Most preferred embodiment 1: get 50 kilograms in fresh multitube algae, use the seawater cleaning and chopping, put into container, the alcohol immersion 2 days that adds 100Kg70%, filter then, filter residue adds 70% ethanol again and soaked 1 day for 60 kilograms, after the filtration twice soak solution is merged, and carries out vacuum-evaporation at 40-60 ℃ and is concentrated into about 5L.
Claims (3)
1. the preparation method of a resisting growth regulator of red alga polyphenols, its characterization method is:
(1), fresh algae is clean with seawater flushing, and shred with knife mill;
(2), with the red algae of chopping with 70～80% alcohol immersion (1-2) sky;
(3), filter soak solution, its filter residue soaked 1 day with ethanol secondary, filter residue discards;
(4) secondary filtration liquid is merged as mother liquor, carry out vacuum-evaporation and concentrate getting final product at 40～60 ℃ then.
2. method according to claim 1 is characterized in that above-mentioned red algae should be a raw material with multitube algae, Rhodomela confervoides and the concave crown algae of being rich in polyphenol.
3. method according to claim 1, get 50 kilograms in fresh multitube algae, use the seawater cleaning and chopping, put into container, the alcohol immersion 2 days that adds 100Kg70% is filtered then, and filter residue adds 70% ethanol again and soaked 1 day for 60 kilograms, after the filtration twice soak solution merged, carry out vacuum-evaporation at 40-60 ℃ and be concentrated into about 5L.
