Description

A kind of solid pharmaceutical preparation containing alginic acid and trace element built and preparation method thereof and Purposes
Technical field
The present invention relates to fertilizer field, has and be related to a kind of solid pharmaceutical preparation and its preparation method and application more particularly to one Solid pharmaceutical preparation and its preparation method and application of the kind containing alginic acid and trace element built.
Background technology
Seaweed acids foliar fertilizer be integrate nutritional ingredient, antibiotics, plant hormone new-type fertilizer.It is by special Different biochemical process processing, essence substance is efficiently extracted out from natural seaweed, natural activity component is greatly remained, contains Various mineral matter elements such as a large amount of non-nitrogen containing organic matter, terrestrial plant incomparable K, Ca, Mg, Fe, Zn, Cu, B and abundant Vitamin, especially rich in specific algal polysaccharides, alginic acid, highly unsaturated fatty acid and a variety of natural plants in seaweed Growth regulator.Therefore, liquid seaweed manure is a kind of novel and multifunctional liquid fertilizer.
Trace element, especially Zn, Mg, Fe, B element are one of trace elements necessary to plant.Zn is with cationic Zn2+Shape State is absorbed by plants.Mobility of the Zn in plant belongs to medium.Zn affects the synthesis of auxin indirectly in crop body, as Growth cellulose content when object lacks Zn in stem and bud is reduced, and growth stays cool, and plant is short and small;Zn is also many enzymes simultaneously Activator by generating wide influence to plant carbon and nitrogen metabolism, therefore contributes to photosynthesis;Zn can also enhance plant simultaneously The resistance of object;Kernel weight is improved, the ratio of seed and cane is changed.Mg is the micro battalion needed for plant normal growth development Element is supported, is the constituent of chlorophyll and plant element, lacking Mg chlorophyll cannot form, and photosynthesis can not carry out;Mg is a variety of The activator of enzyme can promote conversion and its metabolic process of carbohydrate, to the respiration in the metabolism of carbohydrate, crop body Play an important roll;Mg can promote the synthesis of fat and protein, can make phposphate enzyme activation, moreover it is possible to promote vitamin A and C Formation, improve vegetables and fruit quality.Although Fe is not the ingredient of chlorophyll, when ferro element subalimentation, leaf can be made The synthesis of green element is hindered, and chlorosis phenomenon occurs for blade, influences the formation of photosynthesis and carbohydrate, is photosynthesis Essential element;Fe is the indispensable cytochrome oxidase of plant aerobic respiration, catalase, peroxidase Deng group ingredient;Ferredoxin (Fd) is an iron-containing electron transfer protein, is present in chloroplaset (full iron in plant 80% be contained in chloroplaset), take part in the electron transmission of photosynthesis, nitrate reductase, biological nitrogen fixation etc..Boron element promotes thin Born of the same parents extend and tissue differentiation, accelerate enzyme metabolism and lignin is formed, carbohydrate transport and protein metabolism, promote root system life Long development, enhances crop anti-adversity, promotes early ripening of the crops modification, promotes pollen germination and pollen tube growth.
It has been investigated that alginic acid and trace-element fertilizer (micro- fertilizer) collocation are more preferable using fertilizer efficiency, there is synergistic function, Especially zinc fertilizer can more effectively inhibit the generation of virosis.However alga fertilizer and micro- fertilizer currently on the market is water solubility Liquid fertilizer.Mixed in use, since water-soluble alga fertilizer is different from water-soluble micro- adipic acid alkalinity matter in bucket, alga fertilizer shows alkali Property, micro- fertilizer is aobvious acid, is susceptible to precipitation, while reducing the fertilizer efficiency of alginic acid and micro- fertilizer, and the sediment of formation also has blocking to filter The possibility of net and nozzle, makes troubles to user, reduces alga fertilizer and micro- fertile possibility used of arranging in pairs or groups.
CN103044162B discloses a kind of organic water soluble fertilizer containing alginic acid;Wherein 40~50 parts of alginic acids, 15 ~25 parts of humic acid, 10~20 parts of compound amino acids, 3~5 parts of vitamins and trace element mixture, 3~5 parts of urea, 5~8 Part P2O5, 5~8 parts of K2O, 300~500 parts of water compositions.Wherein the vitamin and trace element is that kelp crushes liquid extraction institute ?.Although the patent is alginic acid and trace element built product, but still be liquid fertilizer, and thoroughly solve alga fertilizer with it is micro- Fertilizer may lead to the problem of precipitation because of acid-base value difference.
Invention content
It is water-soluble liquid fertilizer to overcome alga fertilizer on the market and micro- fertilizer, bucket mixes use and is likely to occur precipitation, blocks Mister head and reduce alginic acid and micro- fertilizer fertilizer efficiency defect, the present invention provides one kind can overcome the above problem and The solid pharmaceutical preparation and its preparation method and application of alginic acid and trace element built that is easy to process, storing and use.
For this purpose, present invention employs following technical schemes:
In a first aspect, the present invention provides a kind of solid pharmaceutical preparation containing alginic acid and trace element built comprising sea Alginic acid and solid-state trace element.
The present invention is to provide a kind of solid pharmaceutical preparation containing alginic acid and trace element built, i.e. said preparation is with solid Can be specifically wettable powder or water dispersion granule existing for the form of composition.
Use the composition containing alginic acid and trace element built obtained in the form of solid pharmaceutical preparation, the solid pharmaceutical preparation The defect present in previous Water-soluble liquid fertilizer can effectively be overcome, for example, being needed to it when using Water-soluble liquid fertilizer It carries out the mixed dilution of bucket, and precipitation is easy tod produce due to the incompatibility between alginic acid and trace element when the mixed dilution of bucket, from And the fertilizer efficiency of alginic acid and trace element can be not only reduced, while the precipitation can also block sprayer strainer and nozzle, cause to set Standby abrasion;However when solid pharmaceutical preparation using the present invention, then there is no the generation precipitated when dilution is blended, sea is improved The fertilizer efficiency of alginic acid and trace element;Since it is mixed without bucket, mobility is more preferable, keeps storage transport more convenient.
In the solid pharmaceutical preparation, mass percentage shared by alginic acid is 20~70%, such as 20%, 22%, 25%, 28%, 30%, 32%, 35%, 38%, 40%, 42%, 45%, 48%, 50%, 52%, 54%, 58%, 60%, 62%, 65% or 70%, the mass percentage shared by solid-state trace element is 3~30%, such as 3%, 5%, 8%, 10%, 12%, 15%, 18%, 20%, 22%, 25%, 28% or 30%.
