Embodiment 1

[0021] A nitrogen fertilizer, consisting of the following components by weight: 30 parts of fertilizer substrate, 15 parts of urea, 15 parts of ammonium chloride, 5 parts of boron moist soil, 5 parts of humic acid, 5 parts of microbial bacteria, 22 parts of white stone powder, nitrogen-fixing 3 parts of bacterial agent.

[0022] The raw material components are measured and pulverized, passed through a 120-250 mesh sieve, put into the mixer, mixed and stirred for 20 minutes, and sent to the disc steam granulation through the conveyor belt; the resulting granules enter the dryer for drying, and then cooled by the coolant, and finally Measured packaging.

[0023] After the nitrogen fertilizer was used in a 3-acre soybean experimental field, compared with the application of ordinary nitrogen fertilizer, the application amount of nitrogen fertilizer was reduced by 40%, the soybean yield was increased by 20%, the quality of agricultural products was also improved, and the soil was l...

Embodiment 2

[0025] A nitrogen fertilizer, consisting of fertilizer base, urea, ammonium chloride, boron bentonite, humic acid, microbial bacteria, white stone powder and nitrogen-fixing bacterial agent, is composed of the following components in parts by weight: 40 parts of fertilizer base, 20 parts of urea , 10 parts of ammonium chloride, 6 parts of bentonite, 3 parts of humic acid, 4 parts of microbial bacteria, 16 parts of white stone powder, and 1 part of nitrogen-fixing bacterial agent.

[0026] The raw material components are measured and pulverized, passed through a 120-250 mesh sieve, put into the mixer, mixed and stirred for 20 minutes, and sent to the disc steam granulation through the conveyor belt; the resulting granules enter the dryer for drying, and then cooled by the coolant, and finally Measured packaging.

Abstract

The invention relates to a nitrogenous fertilizer, and relates to the agricultural fertilizer field. The nitrogenous fertilizer is composed of the following ingredients: a fertilizer matrix, urea, ammonium chloride, bentonite, humic acid, microorganism bacteria, white stone powder and a nitrogen-fixing bacterium agent. The nitrogenous fertilizer has an effect of slow and long-acting release of nutrients, the loss rate of the nitrogen nutrient element in soil is lowered, the absorption utilization rate of crops is raised, the nitrogen amount required by the plant growth stage is met through combined action of ammonium chloride and urea, multi-time additional fertilization is not needed, resources are saved and investment is saved. The microorganism bacteria improve the soil structure and promote activity of soil microorganisms, thus soil is loose, the conversion rate of organic and inorganic fertilizers in soil is raised plant chlorophylls are increased, the plant photosynthesis is raised, and soil hardening and desertification and environment pollution caused by application of excess inorganic fertilizers are prevented.

Description

technical field [0001] The invention relates to the field of agricultural fertilizers, in particular to a nitrogen fertilizer. Background technique [0002] my country is a big agricultural country, which feeds 22% of the world's population with 7% of the world's arable land. It can be said that fertilizer plays a decisive role. Fertilizers account for about 40%-60% of the total contribution to crop yield enhancement. Among them, nitrogen fertilizer plays a very important role in the growth of crops. It is a component of amino acids in plants, a component of protein, and a component of chlorophyll that plays a decisive role in photosynthesis of plants. Nitrogen also helps crops disperse. However, many times of fertilization may be required during the entire growth and development of crops. Long-term application of large amounts of nitrogen fertilizers will cause serious land salinization. The reason is that the effective utilization rate of chemical fertilizers is very low...
