Embodiment 1

[0010] First, weigh the following components and their respective weight ratios: 2-10 bio-organic fertilizers, 150 kg of weathered coal, 200 kg of grass carbon, 30 kg of vermiculite, 40 kg of black humic acid, 2 kg of zinc sulfate, 400 kg of urea, 150 kg of potassium dihydrogen phosphate, and 28 kg of water-retaining agent, then crush grass carbon, weathered coal, vermiculite, and urea to a particle size of less than 3 mm, and then mix with black humic acid, zinc sulfate, and potassium dihydrogen phosphate , water-retaining agent for mixing, according to the proportion of the appeal formula, put the larger proportion first and then the smaller proportion of the components, and add them to the mixer in turn, after stirring and mixing evenly, use extrusion granulation method to make the diameter of The particles of 2-5 mm are polished, dried, sieved, measured, and packaged to become the finished water-retaining fertilizer.

Abstract

The invention belongs to the technical field of fertilizers, and relates to a water-retaining organic-inorganic composite fertilizer comprising, by weight: 2-10% of a bio-organic fertilizer, 5-20% of weathered coal, 5-20% of grass carbon, 1-8% of vermiculite, 1-30% of humic acid, 0.1-0.3% of zinc sulfate, 2-60% of urea, 2-50% of potassium dihydrogen phosphate, and 1-10% of a water-retaining agent. According to the invention, grass carbon, weathered coal, vermiculite, and urea are crushed until a particle size is below 3mm; the particles are well mixed with humic acid, zinc sulfate, potassium dihydrogen phosphate, and the water-retaining agent, such that particles with diameters of 2-5mm are prepared; and polishing, bake-drying, sieving, measuring, and packaging are carried out, such that water-retaining organic-inorganic composite fertilizer finished product is obtained. The fertilizer provided by the invention has multiple functions such as water retaining, fertilizer retaining, fertilizer saving, ground temperature adjusting, soil improving, substantial production increasing, fertilizer-efficiency sustained-release, stress resistance improving, low cost, high efficiency, and the like. With the fertilizer, seed germination rate, seedling emergence rate, and seedling transplantation survival rate can be effectively improved, and grain, cotton, fruit, and vegetable production can be increased by 20-45%.

Description

technical field [0001] The invention relates to a fertilizer formula, in particular to a water-retaining organic-inorganic compound fertilizer which has the functions of retaining water, retaining fertilizer, regulating ground temperature, improving soil and effectively increasing the output of agricultural products. Background technique [0002] Agriculture is a major player in water use, water scarcity and water conservation. According to statistics, agricultural water accounts for more than 70% of the country's total water consumption each year, of which 90% is irrigation water. On the one hand, the country’s annual agricultural irrigation water shortage is 30 billion m 3 On the other hand, because most of the national agriculture adopts the traditional method of flood irrigation, the water utilization rate is only 40-45%, and more than 200 billion m is lost or volatilized. 3 water. In addition, in the west of our country, especially in the desert areas, there is gener...
