Problems solved by technology

Traditional BB fertilizers also have shortcomings, that is, "heavy inorganic fertilizers, light organic fertilizers", "heavy macronutrients, light medium and trace elements", "heavy instant dissolution and quick effect, light slow release and controlled release", "heavy nitrogen fertilizers, light phosphorus and potassium fertilizers"" Emphasis on high nutrient content, light on low nutrient content", "emphasis on particle blending, light on powder blending", "emphasis on external quality, light on internal quality", etc., deviate from the true meaning of scientific formula fertilization of BB fertilizer, resulting in waste of resources , pollute the environment, make the cost of agriculture too high, farmers increase production without increasing income
[0003] The conventional BB fertilizer preparation method is simply blended and packaged, which is heavy in water and easy to agglomerate, which affects farmers' application

example 1

[0126] A kind of ecological function BB fertilizer, the proportioning by weight of its raw material is:

[0127] N46 functional urea 350

[0128] N30S8 Controlled Release Sulfur-Containing Urea 350

[0129] N11P 2 o 5 44 monoammonium phosphate 140

[0130] K 2 O40 granulated potassium sulfate 150

[0131] S21Mg27 Granular Agricultural Magnesium Sulfate 10

[0132] The specific preparation method is as follows:

[0133] The qualified formula granules are automatically measured by electronic scales (various special formula metering programs are pre-designed and stored in the computer), enter the mixer for mixing, and then enter the fluidized bed dryer for drying. After drying, enter the fluidized Bed cooler (an air dehumidifier is added to remove the moisture in the cooling air), after cooling, it enters the coating machine and coats with a layer of anti-cleaning block agent (paraffin). After coating, it enters the automatic metering packaging machine for packaging and st...

[0136] A kind of ecological function BB fertilizer, the proportioning by weight of its raw material is:

[0137] N46 functional urea 90

[0138] N30S8 Controlled slow-release sulfur-containing urea 222

[0139] N18P 2 o 5 46 diammonium phosphate 400

[0140] K 2 O40 Granulated Potassium Chloride 250

[0141] S21Mg27 granular agricultural magnesium sulfate 38

[0142] The "cotton-specific" ecological function BB fertilizer product is prepared through the above formula, with a total nitrogen content ≥ 18%, a phosphorus pentoxide content ≥ 18%, a potassium oxide content ≥ 10%, a total sulfur content ≥ 2.5%, and an available magnesium content ≥ 0.75%, trace elements ≥ 2%, nitrogen fertilizer utilization rate increased by 25 percentage points, the fertilizer effect can be achieved in three days at first, and it can reach 100 days at a long time, reducing the amount of fertilizer by about 30%, and increasing cotton production by about 15%.

example 3

[0144] A kind of ecological function BB fertilizer, the proportioning by weight of its raw material is:

[0145] N46 functional urea 180

[0146] N30S8 Controlled slow release sulfur urea 100

[0147] N11P 2 o 5 44 monoammonium phosphate 340

[0148] K 2 O50 Granular Potassium Sulphate 200

[0149] Organic Matter 50% Granular Organic Fertilizer 150

[0150] S21Mg27 Granular Agricultural Magnesium Sulfate 30

[0151] The "fruit-specific" ecological function BB fertilizer product is prepared through the above formula, with a total nitrogen content ≥ 15%, a phosphorus pentoxide content ≥ 15%, a potassium oxide content ≥ 10%, a total sulfur content ≥ 5.5%, and an effective magnesium content ≥ 0.8%, trace elements ≥ 1%, nitrogen fertilizer utilization rate increased by 25 percentage points, fast fertilizer effect can be seen in seven days, and long can reach 150 days, reduce fertilizer consumption by about 30%, and increase fruit production by about 20%.

Abstract

The invention discloses an ecological BB fertilizer, relating to a mutifunctional ecological environment friendly compound fertilizer, which is formed by mixing functional urea, controllable slow release sulfurcoated urea, monoammonium phosphate, diammonium phosphate, potassium sulfate particle (or potassium chloride), agricultural magnesium sulfate particle, ammonium sulfate, bio-organic inorganic compound fertilizer, endophytic PASP fertilizer synergist DA-6, plant growth regulator and trace elements. Special ecological BB fertilizer for different plants can be prepared by soil testing formula, according to different farm crops and different soil structure. The ecological BB fertilizer can take effect for 3-120 days, the nutrition release is balanced, biological stress of the farm crop such as drought resistance, cold resistance, salt resistance, or the like can be improved. The product of the invention has great operation significance for increasing yield of grain, reducing production cost, steadily increasing grain production, keeping rural incomes growing, improving utilization rate of the fertilizer, reducing fertilizer waste, protecting ecological environment, guaranteeing farm crop quality and safety, and ensuring sustainable development of the agriculture.

Description

technical field [0001] The invention relates to a fertilizer, in particular to an ecological function BB fertilizer. Background technique [0002] BB fertilizer is usually called a blended fertilizer, which refers to a fertilizer made of nitrogen, phosphorus, and potassium in which at least 2 nutrients are marked by a dry blending method, and it is a type of compound fertilizer. BB fertilizer can "make up what is lacking" for the soil, and is a carrier of balanced fertilization. Traditional BB fertilizers also have shortcomings, that is, "heavy inorganic fertilizers, light organic fertilizers", "heavy macronutrients, light medium and trace elements", "heavy instant dissolution and quick effect, light slow release and controlled release", "heavy nitrogen fertilizers, light phosphorus and potassium fertilizers"" Emphasis on high nutrient content, light on low nutrient content", "emphasis on particle blending, light on powder blending", "emphasis on external quality, light on ...
