Description
Technical field
The present invention relates to the agricultural fertilizer field, specifically, relate to a kind of nitre sulfenyl organic-inorganic compound fertilizer.
Background technology
Current, the development of China's fertilizer develops to directions such as efficient, compound, slowly-releasings, because granular fertilizer can provide multiple nutritional components, and nutrient is balanced, and aspects such as uses, transportation are convenient and swift, and therefore, development comparatively fast.In addition, the combination of organic-inorganic also makes and has obtained complementation between the nutrient, has reduced the nutrient loss in the fertilizer, simultaneously, utilizes fertilizer to improve soil.
For a long time, because the unreasonable use of macroelement chemical fertilizer has caused the waste of fertilizer and has absorbed unbalanced.Although the peasant strengthens the usage quantity of fertilizer every year, but still can not satisfy the demand of crop growth, even cause crop production reduction.The physiological development of plant nutrition makes balance fertilizing and economic fertilization, becomes the effective means that the world today boosts agricultural yield.Simple common compound fertilizer can not satisfy the needs of farm crop.
Moreover because fertilizer structure is unreasonable, crop absorption, utilization ratio are low, cause the part hardening soil, even cause the underproduction, also bring very big influence to agriculture prodn.
Summary of the invention
The technical problem that the present invention will solve is to overcome above-mentioned defective, and a kind of absorption and utilization ratio height, the permanent nitre sulfenyl organic-inorganic compound fertilizer of fertilizer efficiency are provided.
For addressing the above problem, the technical scheme that the present invention adopted is:
A kind of nitre sulfenyl organic-inorganic compound fertilizer; It is characterized in that: it is made up of following raw material: urea, ammonium sulfate, nitrophosphate fertilizer, vitriolate of tartar, humic acids and dilute sulphuric acid, wherein the weight part of urea, ammonium sulfate, nitrophosphate fertilizer, vitriolate of tartar, humic acids is urea 100, ammonium sulfate 200, nitrophosphate fertilizer 300, vitriolate of tartar 100, humic acids 300.
Say further: the nitrogen content of said urea is 46.3%, and the nitrogen content of ammonium sulfate is 20%, and the nitrogen content of nitrophosphate fertilizer is 11.5%, phosphorus content is 26.5%, K in the vitriolate of tartar
2The content of O is 50%, and content organic in the humic acids is 68%.
Press the above-mentioned raw materials formulated; The nitre sulfenyl organic-inorganic compound fertilizer of producing; Can reach through detecting index: one ton of nitre sulfenyl of every production organic-inorganic compound fertilizer, the nutrient of nitrogen can reach 12.08%, the nutrient of phosphorus can reach 7.95%, the nutrient of potassium can reach 5.0%, organic nutrient 20.4%.
Effective ingredient of the present invention:
Nitrogen, phosphorus, potassium, organic matter, sulphur.
In the prescription of the present invention, the effect of each raw material is following:
Urea is used in right amount and can be promoted that the crop cauline leaf is in great numbers, tillers and increases, and full seed improves the output protein contnt of crop.
Nitrophosphate fertilizer can pass through ammonium nitrogen, nitric nitrogen; The organic assembling of water-soluble phosphorus, inflexible dissolubility phosphorus; Both satisfied the needs of plant different steps growth, and can reduce the waste of fertilizer again well, also having an important effect is exactly the resistance that it can increase crop.
Vitriolate of tartar can make long strong of farm crop cane, can prevent lodging, promotes farm crop to bloom with solid, and can the enhancing crop drought resisting, the ability of cold-resistant, disease and insect resistance.
Humic acids has another name called and is agron, has moderate cohesiveness, can make clay loose or form a unity structure, and the guarantor that can improve soil is fertile, water retention capacity, the variation of buffering soil acidity or alkalinity.
The content that dilute sulphuric acid can increase sulphur can improve the granulation environment again.
In sum, the present invention has following effect:
The present invention is a desirable fertilizer of producing green food, has the yield and quality that improves crop, can reduce residue and the nitrate salt of chemical fertilizer in the agricultural-food, agricultural chemicals, the content of nitrite; Improving nutrient composition contents such as protein, amino acid, is the first-selected product of development pollution-less agriculture, and this product has the reduction environmental pollution; Optimize planting environment, help the sustainable and healthy development of the ecological agriculture and high-efficiency agriculture, can reduce the generation of disease and pest in the soil; Has degeneration-resistant, anti-continuous cropping; Increase the photosynthesis of plant, promote that growth and development of plant makes fruit attractive in appearance, characteristics such as fresh-keeping anti-storage, anti-transportation.Culture fertility is improved the soil, and helps the enhancing of the soil organism after the use, and it is good to make soil form the crumb structure performance, and drought resisting, water conservation, guarantor's fertilizer promote that the well developed root system stalk is sturdy, keep soil from packing together effects such as activating soil nutrient.
The present invention is applicable to the soil that basicity is too high; Has the too high effect of adjustment soil alkalinity; To wheat, corn, peanut, vegetables, 1,000 mu of experiments of fruit tree warp; The grain farm crop are on average increased production more than 20.8%, and economic farm crop are on average increased production more than 23.5%, and vegetables are on average increased production more than 34% by farm crop.
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Description of drawings
Accompanying drawing is technological process of production figure of the present invention.
Embodiment
Embodiment:
A kind of nitre sulfenyl organic-inorganic compound fertilizer; Formed by following preparation of raw material: urea, ammonium sulfate, nitrophosphate fertilizer, vitriolate of tartar, humic acids and dilute sulphuric acid, wherein the weight part of urea, ammonium sulfate, nitrophosphate fertilizer, vitriolate of tartar, humic acids is urea 100, ammonium sulfate 200, nitrophosphate fertilizer 300, vitriolate of tartar 100, humic acids 300.
