Abstract
The invention discloses an organic and inorganic fertilizer for improving the high and medium nutrient contents of soil and a preparation method thereof. The fertilizer is prepared in such a way that raw materials containing humic acid, large granular urea, ammonium phosphate and blood attapulgite powder are uniformly mixed and then granulated, baked, cooled, sieved, recycled and packaged by a conventional method, or the raw materials are granulated, baked, cooled, sieved and recycled by the conventional method to obtain a granulated intermediate good, then 10 percent of the total amount of humic acid is sprayed onto the measured large granular urea, and the granulated intermediate good and the large granular urea sprayed with humic acid are mixed, uniformly stirred, and packaged after the moisture content H2O is detected to be not more than 2 percent to obtain the finish product. Powdery potassium chloride and ammonium chloride or powdery potassium sulfate can be also respectively added into the raw materials as required, so as to be prepared into the fertilizer containing chlorine or the fertilizer containing no chlorine. The organic and inorganic fertilizer can improve the soil, the soil organism fertility and the utilization ratio of nutrients containing phosphorus, potassium, and the like in soil, and has the advantages of environment protection, safety and simple preparation process.
Description
Technical field
The present invention relates to fertilizer, especially relate to the organic and inorganic fertilizer and the preparation method of senior middle school's nutrient content of improving the soil of a kind of green, environmental protection, safety.
Background technology
Fertilizer is supplied with big or middle, the micronutrient nutrient of agriculture farm crop, forestry trees flowers, aquaculture forage feed.With animal excrement, riverway sludge and industrial available waste residue prepared organic-inorganic complex fertilizer, its (N+P
2O
5+ K
2O) content is not high, and general all 15%～25%, plant recovery of nutrient is not high, and the composite fertilizer that makes with mineral manure not only plant recovery of nutrient is not high, and use improper polluting the environment, make soil compaction.And, be difficult to also accomplish that the low balance formula that drops into of saving of labor applies fertilizers scientifically.
Summary of the invention
The object of the present invention is to provide and a kind ofly can improve the soil, improve the soil organisms fertility, improve the organic and inorganic fertilizer and the preparation method of senior middle school's nutrient content of utilization ratio, the environmental protection safety of nutrients such as phosphorus potassium in the soil.
The object of the present invention is achieved like this:
A kind of organic and inorganic fertilizer of senior middle school's nutrient content of improving the soil, feature is: contain following raw material in weight part:
Humic acids (butt, You Ji Zhi ≧ 60%; H
2O=35%): 35～40
Granular urea (N ≧ 46%): 0～40
Attapulgite: 0～40
Ammonium phosphate: 7～35.
In above-mentioned fertilizer, also be added with following raw material in weight part, to make chloride type fertilizer:
Repone K (K
2O ≧ 60%): 4～50 ammonium chlorides (N ≧ 25%): 0～40.
Or, in above-mentioned fertilizer, also can add following raw material in weight part, to make the non-chloride type fertilizer that is applicable to fear-chlorion crop:
Vitriolate of tartar (K
2O ≧ 60%): 4.5～45.
First kind of preparation method of the present invention (not adding urea) is: after powdered humic acids, ammonium phosphate and attapulgite are measured respectively; mix; stir, carry out granulation, oven dry, cooling, screening, returning charge, water content H after testing more according to a conventional method
2O ≦ 8% gets product after the packing.
Second kind of preparation method of the present invention (adding Bi Li ≦ 5% that urea accounts for the fertilizer gross weight) is: earlier with the granular urea pulverize; after again powdered granular urea, humic acids, ammonium phosphate and attapulgite being measured respectively; mix; stir; carry out granulation, oven dry, cooling, screening, returning charge, water content H after testing more according to a conventional method
2O ≦ 2% gets product after the packing.
The third preparation method of the present invention (adding Bi Li ≧ 5% that urea accounts for the fertilizer gross weight) is: after powdered ammonium phosphate, attapulgite and the humic acids that accounts for total amount 90% are measured respectively; mix; stir; carry out granulation, oven dry, cooling, screening, returning charge, water content H after testing more according to a conventional method
2O ≦ 1.5%, product in the middle of the granulation, be sprayed on the granular urea after the metering with 10% of humic acids total amount then, after testing water content H
2O ≦ 2.2%, at last with product in the middle of the granulation with spray humic acids after granular urea mix, stir, after testing water content H
2O ≦ 2% gets product after the packing.
In above-mentioned three kinds of preparation methods, also can add powdered Repone K and ammonium chloride or powdered vitriolate of tartar as required respectively, to make chloride type fertilizer or non-chloride type fertilizer.
The present invention is on the basis of balance fertilizing, adds the humic acids of significant quantity, can reduce soil to quick-acting phosphorus fixations with the humic acids of natural brown coal association, promotes absorbing of phosphorus; Humic acids can absorb and store potassium ion, both can prevent that soil potassium from losing with current, and can avoid clay mineral again, certain corrosion arranged containing potassium-bearing minerals such as potassium silicate, potassium felspar sand to potassium fixation, can slowly decompose and increase the release of potassium, improve the level of the effective potassium content of soil; Humic acids is a kind of organic colloid, can promote the formation of coacervate in soil, helps to improve Soil structure, regulates the soil water, fertilizer, gas, thermal conditions; Humic acids can promote the soil microorganisms activity, makes cellulase in the soil, Phosphoric acid esterase, protease activity improve 6%～42%, and visible humic acids is being improved the soil, improved the soil organisms fertility, improving in the soil plant recovery of nutrient such as phosphorus potassium and have vital role.Attapulgite is the binding agent in the as fertilizer sources, and it also can replace with bentonite in powder or zeolite powder.
Therefore, the present invention has utilization ratio, environmental protection safety, the simple advantage of preparation technology that can improve the soil, improve the soil organisms fertility, improve nutrients such as phosphorus potassium in the soil.
