Abstract
The invention relates to a preparation method for promoting crop growth by reducing organophosphorous residues. The preparation method provided by the invention further has remarkable characteristics that no exhaust gas and wastewater pollute environment in the production process, raw materials are easily available, process is simple, investment is small, and the like. Therefore, the preparation method not only is suitable for demand on technical improvement of the existing tea polyphenol plants and brown alga processing enterprises so as to improve the benefit, but also can be used for production and popularization and application in rural small and medium-sized enterprises. The preparation method is a novel technology which is imperative in current green food production.
Description
Technical field
The present invention relates to a kind of preparation method reducing machine phosphorus insecticide residue promotion plant growth.
Background technology
China has a large population in a small area, and how to ensure that size of food safety and quality safety are long-term and difficult task.With regard to plant resource food, no matter be large grain-production, or the production of vegetable and fruit, their growth busy season is also is mostly that the busy season occurs in insect pest.Present stage is the seed output and quality improving them, and peasant also needs to use chemical pesticide control insect pest.Along with the complete prohibition use of organo-chlorine pesticide and pyrethroid pesticide easily make insect develop immunity to drugs, current organophosphorous pesticide account for 70% of insecticide total amount.But long-term large-scale production and use organophosphorous pesticide, not only cause severe contamination to environment, residual in food and feed also have serious impact to people and cultivated animals.And carry out transgenic pest-resistant, the research of disease-resistant crop, construction, biopesticide and the exploitation of organophosphorous pesticide substitute and the superseded use of some organophosphorous pesticide of the base area of green food or reach in food hygienic standard and all need very strong science and technology and business models without detecting requirement etc.Therefore, develop a kind of can degraded and do the residual of organophosphorous pesticide in object, the biologic product of plant growth can be promoted again to be current and from now on institute in the urgent need to.
Summary of the invention
An object of the present invention is the deficiency overcoming prior art, provides a kind of and reduces the preparation method that machine phosphorus insecticide residue promotes plant growth.
Another object of the present invention is to the higher value application promoting tealeaves and brown alga industrial enterprise discarded object.
Preparation method 1: do not add rare earth and directly utilize the preparation method of tealeaves and brown alga industrial enterprise discarded object: A, directly utilize Tea Processing Tea Polyphenols and caffeine after adjust ph to 4 ~ 7 after to utilize after kelp processing mannitol, sodium alginate concentrated containing brown alga oligose waste liquid containing tea polysaccharide waste liquid and B, filter, and further concentrated liquid biologic product, dry solid-state biologic product
With the biologic product of said method processing, on the crop spraying organophosphorous pesticide, application can make organophosphorous pesticide degradation rate after a couple of days reach more than 80%, and crop yield rate is 3 ~ 20%, and crop yield probability is about 85%.In addition, this biologic product is a kind of natural medicine or the rare earth containing small amount, thus not only considerably reduces the usage amount of rare earth, improves the safety of rare earth application, and makes the tealeaves of China's abundant and brown alga resource obtain abundant higher value application.
The present invention also has production process without waste gas, contaminated wastewater environment, raw material is easy to get, technique is simple, invest the distinguishing features such as very little, therefore the technological transformation needs of existing Tea Polyphenols factory and brown alga processing enterprise are not only applicable to, improve its benefit, and can produce in rural area medium-sized and small enterprises and be applicable, be current pollution-free food production in the urgent need to a kind of new technology.
Embodiment
Tea polysaccharide or sea-tangle discarded object warm water dissolve, solubility control is 2% ~ 35%, then slowly add in advance with the rare earth of dilute nitric acid dissolution or directly use nitric acid rare earth, rare earth adding quantity controls 0.00% ~ 0.5%, pH controls 2 ~ 6, and after remaining on 25 DEG C ~ 35 DEG C reaction 24h, with acid, alkali fine setting reacting liquid pH value to 4 ~ 7.Concentrated liquid biologic product after filtering, or dry solid-state biologic product.The final products no matter prepared are liquid state or solid-state shape, and all should include active ingredient carbohydrate in their every mu of usage amount is 30g ~ 150g (by input raw material), and rare earth is 0.0001g ~ 20g (by input raw material).Rare earth used in above-mentioned preparation method directly can plant element or other arsenic determination by benefit, and this biologic product field using method is with conventional biologic product using method.

Embodiment 2
Be dissolved in 1000ml water with the waste liquid thing 50g after kelp processing mannitol, sodium alginate, slowly add 0.3g benefit and plant element, after remaining on 25 DEG C of reaction 24h, with nitric acid fine setting reacting liquid pH value to 6.5, concentrated liquid biologic product after filtering, or dry solid-state biologic product.No matter be liquid biologic product, or solid-state biologic product, sea-tangle discarded object content 500g, content of rare earth 3g in every mu of usage amount.
Embodiment 3
With after concentrated containing tea polysaccharide waste liquid after Tea Processing Tea Polyphenols and caffeine, after leaving standstill 24h, the biologic product filtering liquid, and then dry solid-state biologic product.Containing tea polysaccharide solid content 500g in every mu of usage amount.
Embodiment 4
After concentrated with the waste liquid after kelp processing mannitol, sodium alginate, with nitric acid fine setting pH value to 6, the biologic product filtering liquid, and then dry solid-state biologic product.Thallus Laminariae (Thallus Eckloniae) extract content 500g in every mu of usage amount.
Claims (2)
