Embodiment 1

[0013] A long-acting slow-release and controlled-release corn special fertilizer, which is prepared from potassium chloride, monoammonium phosphate, ammonium chloride, urea, boron mud, humic acid, fermented edible fungus residue, and biological functional fungus raw materials. The weight of raw materials is: 5% potassium chloride, 7% monoammonium phosphate, 20% ammonium chloride, 20% urea, 11.1% boron mud, 17% humic acid, 19.65% fermented edible fungus residue, biological Functional bacteria 0.25%.

[0014] Stir, granulate, dry, pass through the raw materials of each proportioned component, pass through a reciprocating vibrating sieve with an aperture of 1.5 mm, and screen to obtain particles with a particle size less than or equal to 1.5 mm.

[0015]

[0016] As can be seen from Table 1, the application of the long-acting slow- and controlled-release corn special fertilizer described in Example 1 has little difference in the impact of different fertilizer varieties on th...

Embodiment 2

[0018] A long-acting slow-release and controlled-release corn special fertilizer, which is prepared from potassium chloride, monoammonium phosphate, ammonium chloride, urea, boron mud, humic acid, fermented edible fungus residue, and biological functional fungus raw materials. The weight of raw materials is: 6% potassium chloride, 9% monoammonium phosphate, 18% ammonium chloride, 19.65% urea, 10% boron mud, 15.1% humic acid, 22% fermented edible fungus residue, biological Functional bacteria 0.25%.

[0019] Stir, granulate, dry, pass through the raw materials of each proportioned component, pass through a reciprocating vibrating sieve with an aperture of 4.0 mm, and screen to obtain particles with a particle size smaller than or equal to 4.0 mm.

[0020]

[0021] As can be seen from Table 2, the long-acting slow-release corn special fertilizer described in application example 2 and the application of 45% western compound fertilizer and corn special fertilizer can improve co...

Embodiment 3

[0023] A long-acting slow-release and controlled-release corn special fertilizer, which is prepared from potassium chloride, monoammonium phosphate, ammonium chloride, urea, boron mud, humic acid, fermented edible fungus residue, and biological functional fungus raw materials. The weight of raw materials is: 7.7% of potassium chloride, 9.1% of monoammonium phosphate, 13% of ammonium chloride, 22% of urea, 10% of boron mud, 20% of humic acid, 18% of fermented edible fungus residue, biological Functional bacteria 0.2%.

[0024] Stir, granulate, dry, pass through the raw materials of each proportioned component, pass through a reciprocating vibrating sieve with an aperture of 2.5 mm, and screen to obtain particles with a particle size smaller than or equal to 2.5 mm.

[0025]

[0026] As can be seen from Table 3, the long-acting slow-release controlled-release corn special fertilizer described in application example 3 and the use of 45% western compound fertilizer and corn spe...

Abstract

The invention provides a special long-acting controlled-release fertilizer for corns. Potassium chloride, monoammonium phosphate, ammonium chloride, urea, boric sludge, humic acid, fermented edible mushroom dreg and biological functional bacteria are mixed in proportion, pelleted, dried, cooled, and screened to obtain particles with particle sizes less than or equal to 4.0mm. The fertilizer is novel green and environment-friendly fertilizer, the component collocation is reasonable; all nitrogenous fertilizer, phosphate fertilizer, potash fertilizer, microelements and beneficial biological bacteria meeting fertilizer demands of the corns during an entire breeding season are combined to be applied into soil prior to seeding; topdressing is not required any longer; the fertilization quality can be ensured; the fertilization effect is improved; the inconvenience arising from the topdressing at high temperature in midsummer is avoided; the labor intensity is reduced; the labor employment is saved; and the fertilizer has a very important significance in protecting grain planting enthusiasm of farmers, national grain safety and socialistic new rural construction.

Description

[0001] technical field [0002] The invention relates to the technical field of agricultural fertilizers, in particular to a special fertilizer for long-acting slow- and controlled-release corn. Background technique [0003] Corn is a food and feed crop. With the continuous extension of its industrial chain, it has become a strategic resource for agricultural product processing. Among the cereal crops in the world, the planting area and total output of corn ranks third after wheat and rice, and the average yield per unit area ranks first. my country's corn cultivation area and total output both rank second in the world. [0004] In the process of corn planting, fertilization is one of the most important agricultural production measures. In the proverb, "there is no harvest due to water, and more harvest and less harvest are due to fertilizer", which vividly shows the importance of fertilizer on the increase and decrease of yield and the improvement of quality. At present, ...
