Problems solved by technology

[0003] In order to pursue high yields, farmers often use a large amount of single chemical fertilizers such as urea and ammonium bicarbonate, coupled with relatively backward production facilities and management measures, resulting in low fertilizer utilization efficiency, secondary salinization of soil, groundwater pollution and crop quality. A series of environmental pollution and food safety issues such as decline

Embodiment

[0051] Example :Preparation of multi-form nitro compound fertilizer (22-10-10)

[0052] The raw material components are as follows:

[0053] 100 parts of urea,

[0054] 425 parts of ammonium nitrate,

[0055] 98 parts of ammonium sulfate,

[0056] 200 parts of potassium sulfate,

[0057] 175 parts of monoammonium phosphate,

[0058] 2 parts of medium and micro-fertilizer;

[0059] Among them, the nitrogen content in monoammonium phosphate is 10%, and the phosphorus pentoxide content is 50%.

[0060] production method:

[0061] (1) Mix urea and ammonium nitrate phosphorus at the bottom of the tower, add them to the ammonium nitrate melter after mixing, melt at a high temperature of 140°C, the molten slurry enters the buffer tank, pressurize by the transfer pump, and send it to In the first-level mixing tank at the top of the tower;

[0062] (2) Put potassium sulfate, ammonium sulfate, and medium and micro-fertilizer into a mixer for thorough mixing. After crushing and sieving, the mixed raw m...

Abstract

The invention discloses a polymorphic nitro-compound fertilizer, relating to the technical field of agricultural fertilizers. The polymorphic nitro-compound fertilizer comprises the following raw materials in parts by weight: 30-150 parts of urea, 160-600 parts of nitramine phosphorus, 0-120 parts of ammonium sulfate, 180-250 parts of potassium sulphate, 100-200 parts of monoammonium phosphate and 1-10 parts of medium and micro fertilizers. The polymorphic nitro-compound fertilizer is produced by mixing, granulating and cooling the raw materials. The polymorphic nitro-compound fertilizer adopts scientific proportion, has complete nutrition, can continuously nourish crops at gradient so as to be more beneficial to the full absorption of the vegetable crops, and can remarkably promote the growth and high and stable yield of the crops, thus having strong market competitiveness.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to a polymorphic nitro compound fertilizer. Background technique [0002] At present, the excessive and unreasonable use of chemical fertilizers has caused a series of negative effects. In our country, the phenomenon of excess and abuse of chemical fertilizers is very common, and the utilization rate of ordinary chemical fertilizers is relatively low. A large number of investigation and research results show that the seasonal utilization rate of nitrogen fertilizer is only 30% to 35%, that of phosphorus fertilizer is 10% to 20%, and that of potassium fertilizer is 30% to 50%. [0003] In order to pursue high yields, farmers often use a large amount of single chemical fertilizers such as urea and ammonium bicarbonate, coupled with relatively backward production facilities and management measures, resulting in low fertilizer utilization efficiency, secondary saliniza...
