Embodiment Construction

[0011] A special machine-applied controlled-release fertilizer for winter wheat, made of the following raw materials in parts by weight (kg):

[0012] Ammonium bicarbonate 30, urea 12, monoammonium phosphate 15, potassium chloride 4, ammonium molybdate 2, manganese sulfate 3, borax 1, ferrous sulfate 1, bamboo charcoal powder 4, sepiolite powder 4, barite powder 2, silane Coupling agent KH550 2, humic acid 2, waste engine oil 2, chlorinated paraffin, appropriate amount of wintergreen oil.

[0013] A method for preparing a controlled-release fertilizer applied by a special machine for winter wheat, comprising the following steps:

[0014] (1) Melt urea, mix borax, ferrous sulfate, sepiolite powder, bamboo charcoal powder and waste engine oil evenly, add to the melted urea, stir evenly, granulate, cool and crush into coarse powder;

[0015] (2) Mix other ingredients such as ammonium bicarbonate other than dechlorinated paraffin with the coarse powder described in step (1), stir...

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

technical field [0001] The invention relates to a fertilizer, in particular to a special machine-applied controlled-release fertilizer for winter wheat and a preparation method thereof. Background technique [0002] In my country, wheat is one of the main food crops. At present, there is a serious shortage of labor force in rural areas in our country. Field management in wheat planting areas mainly relies on the elderly and women. It is urgent to realize the mechanization and simplification of operations such as sowing, harvesting, and fertilization. Loss, improve utilization efficiency. Existing slow-release fertilizers suitable for machine-applied wheat have not been reported yet. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a controlled-release fertilizer applied by a special machine for winter wheat and a preparation method thereof. The present invention fertilizes once, does not need topdressing, has ...
