Description
Technical field
The invention belongs to the composite fertilizer additive technical field, be specifically related to a kind of polar-molecule composite fertilizer additive.
Background technology
The farmland uses single nutrient chemical fertilizer to have many defectives, and the developing direction of China's chemical fertilizer industry at present and in the future is to greatly develop the compound manure of many nutrients.Along with significantly increasing of compound manure output and being extensive use of in the farmland, the research and development development of composite fertilizer additive is very fast, has several prods to come out one after another.But these additive effects are single, and the effect that has is also not satisfactory.On the basis of drawing domestic and international soil science, fertilizer science and Plant Nutrition newest research results, the scientific and technical personnel of Hua Yang company have developed the composite fertilizer additive with multiple remarkable efficacy.
Summary of the invention
The objective of the invention is for overcoming disadvantages of background technology, and a kind of activating soil is provided, strengthen fertilizer efficiency, promote the plant metabolism effect, promote crop precocious polar-molecule composite fertilizer additive.
To achieve these goals, the technical solution used in the present invention is: a kind of polar-molecule composite fertilizer additive is characterized in that raw material composition and the weight percentage of making this additive are:
Ammonium humate 28～43% soya-bean cakes 26～42% amino acid powders 5～15%
Seaweed powder 5～15% Tripotassium Citrates 5～15% fixed nitrogen catalyzer 0.5%
Plant-growth regulator 0.1%.
Humic acids content is greater than 20% in the ammonium humate among the present invention, and protein content is greater than 30% in the soya-bean cake, and the mixed amino acid content is greater than 40% in the amino acid powder, and phospholipids content is greater than 20% in the seaweed powder, and Tripotassium Citrate is industrial goods; The fixed nitrogen catalyzer is a cobaltous sulfide, and plant-growth regulator is a growth hormone.Humic acids, amino acid, protein, Tripotassium Citrate can promote photosynthesis of plant, improve sugar content in the agricultural-food; Humic acids, amino acid, protein, fixed nitrogen catalyzer can be improved the soil, and improve edatope, culture fertility; Humic acids, amino acid energy activating soil increase fertilizer efficiency; Amino acid, albumen mass-energy promote plant metabolism effect, increasing yield and improving quality; Phosphatide, amino acid, plant-growth regulator can be regulated plant vital activity, strengthen the drought resisting of crop, anti-adversity ability such as cold-resistant, resistant to lodging, can promote the crop precocity; Humic acids, amino acid, protein etc. can be eliminated the negative impact of chloride composite fertilizer to plant.
The present invention will contain the multiple material of polar molecule, as ammonium humate, amino acid powder, seaweed powder, Tripotassium Citrate, fixed nitrogen catalyzer and plant-growth regulator science compatibility by a certain percentage, be crushed to the 80-100 order with pulverizer, add again in the compound manure as additive.
The present invention compared with prior art has the following advantages:
(1) promotes photosynthesis of plant, improve sugar content in the agricultural-food
The organic substance that contains in this product is in decomposition course, except that generating the necessary nutritive element of plant growth, also produce the essential carbonic acid gas of photosynthesis, protein that contains in the product and organic potassium in addition, they can improve the activity of many enzymes in the photosynthesis, make plant can more effectively carry out the synthetic and conversion of carbon assimalation and sugar, thereby improved sugar content in the product.
(2) improve the soil, improve edatope, culture fertility
The organic substance that contains in this product is the one side mineralization in decomposition course, discharge nutrient, on the other hand, in the process of carrying out humify, can improve the soil and create good edaphic condition (, promote the formation of good soil structure, adjustment apertures state, change the acid-basicity of soil etc.) as the improvement quality; The fixed nitrogen catalyst vulcanization cobalt that contains in the product can quicken root nodule bacterium molecular nitrogen is reduced to ammonia; The humic acids that contains in the product, protein, amino acid etc. provide abundant carbon source for the life of soil organisms, thereby improved the living condition of soil microorganisms, activity, decomposition and release effective nutrient in soil by microorganism, culture fertility, simultaneously microbiological degradation and product in the biologically active substances such as amino acid, humic acids that contain, improved crop growth environment, the amino acid that contains in the product is the soda acid amphoteric substance, meet alkali and be acid, meet acid and be alkalescence, acid soil can be improved, also alkaline soil can be improved.
(3) activating soil increases fertilizer efficiency
The organic acid that contains in this product can make the insoluble material in the soil be converted into soluble nutrient, and the effect of explaining potential nutrient in the soil is arranged, and can reach 5-13.6%, 7-15.7% and 8-16.6% respectively to the transformation efficiency of nitrogen, phosphorus, potassium in the soil.
(4) promote plant metabolism effect, increasing yield and improving quality
The amino acid that contains in this product, protein etc. have biocatalysis (because often a certain specific metabolism of plant just has a kind of corresponding enzyme to participate in to various metabolic processes in plant materials, enzyme itself is exactly a protein), nitrogen in the product, phosphorus play an active part in the intravital metabolism of plant, potassium is again the activator of plurality of enzymes, various metabolic acceleration of plant and coordination undoubtedly can increasing yield and improving qualities.
(5) regulate plant vital activity, strengthen the drought resisting of crop, anti-adversity ability such as cold-resistant, resistant to lodging
The phosphatide that contains in this product is biomembranous important component part, and microbial film then is to guarantee and adjust the passage that material enters cell.Have selectivity because it is come in and gone out to material, thereby regulated vital movement: the phosphorus in the product, can improve protoplasma colloidal hydration levels and cyto-architectural water-filling in the cell, thereby improve the ability of protoplasma colloid maintenance water, make moisture be difficult for forfeiture.Simultaneously, phosphorus can promote the root system development, root is stretched in the darker moistening soil layer to be gone to absorb water, potassium in the product can accumulate more in crop cell liquid, the osmotic pressure of enchylema is increased, and moisture is moved to the root system of high density from the soil solution of lower concentration, make crop can effectively utilize soil moisture, and keep in vivo.Potassium can make protoplasma colloid water-filling expand, and improves the constraint ability of colloid to water, reduces the transpiration of moisture, has improved the drought-resistant ability of crop.Potassium in the product can also promote the fascicular growth of cane, increases the lodging tolerance of plant.Phosphorus can promote the metabolism of carbohydrate, improves the content of soluble sugar in the plant materials, makes plasmic freezing point decline in the cell, thereby makes the plant physical efficiency keep protoplasma to be in standard state at low temperatures, strengthens its winter resistance.
(6) promote the crop precocity
The crop growth regulator that contains in this product plays growth-promoting functions in process of crop growth, made crop precocious 7-10 days.
(7) the heavy metal ion effect that contains in amino acid that contains in this product and the compound manure generates insoluble chemical compound, has eliminated heavy metal ion to soil and Toxicity in Crops.
(8) protein that contains of this product has and regulates and katalysis, can eliminate in the chloride compound manure chlorion to the negative impact of crop.
(9) low input, high yield.
