Abstract

The invention discloses a machine-applied controlled-release fertilizer special for winter wheat and a preparation method thereof. The machine-applied controlled-release fertilizer special for the winter wheat is prepared from the following raw materials: by weight, 30-35 parts of ammonium bicarbonate, 10-12 parts of urea, 15-18 parts of monoammonium phosphate, 4-6 parts of potassium chloride, 1-2 parts of ammonium molybdate, 2-3 parts of manganese sulfate, 1-2 parts of borax, 1-2 parts of ferrous sulphate, 4-6 parts of bamboo charcoal powder, 3-4 parts of meerschaum powder, 1-2 parts of barite powder, 1-2 parts of silane coupling agent KH550, 2-3 parts of humic acid, 1-2 parts of waste engine oil, and proper amounts of chlorinated paraffin and wintergreen oil. In the formula of the machine-applied controlled-release fertilizer special for the winter wheat, the bamboo charcoal powder and the meerschaum powder can absorb trace elements and play a slow-release effect. The urea is melted and coats the trace elements, so that the urea and the trace elements can be simultaneously released so as to benefit synergy among fertilizers. The waste engine oil coats the trace elements so as to play the slow-release effect. When the fertilizer is applied, compared with a traditional fertilizer, the machine-applied controlled-release fertilizer special for the winter wheat can be used in single-dose application without additional fertilization. Wheat yield can be increased by 16% to 28%, and soil fertility also can be improved.

Description

The winter wheat special machine is executed release and release control fertilizer and preparation method thereof

Technical field

The present invention relates to a kind of fertilizer, specifically a kind of winter wheat special machine is executed release and release control fertilizer and preparation method thereof.

Background technology

In China, wheat is one of staple food crop.Present China rural laborer wretched insufficiency, the field management in wheat planting district mainly relies on old man and women, in the urgent need to realizing mechanize, the simplification of the operations such as sowing, results, fertilising, preferably can single-dose application, need not topdress, save labour cost, reduce fertilizer loss, improve utilising efficiency.The existing machine that is suitable for is executed the slow-release fertilizer of wheat special use and be yet there are no report.

Summary of the invention

For the deficiencies in the prior art, the invention provides a kind of winter wheat special machine and execute release and release control fertilizer and preparation method thereof, single-dose application of the present invention need not be topdressed, and fertilizer loss is few, and release period is long, can satisfy the wheat growth needs.

Technical solution of the present invention is as follows:

A kind of winter wheat special machine is executed release and release control fertilizer, it is characterized in that being made by the raw material of following weight part:

Bicarbonate of ammonia 30-35, urea 10-12, monoammonium phosphate 15-18, Repone K 4-6, ammonium molybdate 1-2, manganous sulfate 2-3, borax 1-2, ferrous sulfate 1-2, bamboo charcoal powder 4-6, sepiolite powder 3-4, ground barium sulfate 1-2, Silane coupling agent KH550 1-2, humic acids 2-3, used oil 1-2, clorafin, wintergreen oil are an amount of.

Described winter wheat special machine is executed the preparation method of release and release control fertilizer, it is characterized in that may further comprise the steps:

(1), with urea fusing, after borax, ferrous sulfate, sepiolite powder, bamboo charcoal powder and used oil mixed, join in the urea of fusing, after stirring, granulation is ground into meal after the cooling;

(2), will fall outer other compositions such as bicarbonate of ammonia of clorafin and mix with the described meal of step (1), stir, clorafin is sprayed in granulation more outward, after the cooling, sprays wintergreen oil again, and get final product.

Bamboo charcoal powder, sepiolite powder play the effect of absorption trace element in the present invention's prescription, play slow release effect, simultaneously, urea fusing peplos is outside trace element, so that urea discharges synchronously with trace element, be conducive to work in coordination with between the fertilizer, used oil is at micro-peplos, play slow releasing function, compare with conventional fertilizers, single-dose application need not be topdressed, wheat yield improves 16-28%, can improve soil fertility simultaneously.

Embodiment

A kind of winter wheat special machine is executed release and release control fertilizer, is made by the raw material of following weight part (kilogram):

Bicarbonate of ammonia 30, urea 12, monoammonium phosphate 15, Repone K 4, ammonium molybdate 2, manganous sulfate 3, borax 1, ferrous sulfate 1, bamboo charcoal powder 4, sepiolite powder 4, ground barium sulfate 2, Silane coupling agent KH550 2, humic acids 2, used oil 2, clorafin, wintergreen oil are an amount of.

The winter wheat special machine is executed the preparation method of release and release control fertilizer, may further comprise the steps:

(1), with urea fusing, after borax, ferrous sulfate, sepiolite powder, bamboo charcoal powder and used oil mixed, join in the urea of fusing, after stirring, granulation is ground into meal after the cooling;

(2), will fall outer other compositions such as bicarbonate of ammonia of clorafin and mix with the described meal of step (1), stir, clorafin is sprayed in granulation more outward, after the cooling, sprays wintergreen oil again, and get final product.

Compare with conventional fertilizers, single-dose application need not be topdressed, and wheat yield improves 16-28%, can improve soil fertility simultaneously.

Claims (2)

1. a winter wheat special machine is executed release and release control fertilizer, it is characterized in that being made by the raw material of following weight part:
