Embodiment 1

[0035] Example 1, a functional zinc-rich nitrogen-fixing biological fertilizer, including the following components in parts by mass: zinc-rich minerals: 26%, EM bacteria: 33%, humic acid: 41%.

[0036] Zinc-rich minerals are calcined at 1600-1800°C. After calcination, harmful heavy metals are removed by extraction, EM bacteria are added to the extracted minerals and fermented for 7 days. After the fermentation, zinc and organic matter are activated. neutral minerals, grind the neutral minerals to a particle size of 30 mesh, add humic acid, mix evenly, and obtain functional zinc-rich nitrogen-fixing biological bacterial fertilizer.

Embodiment 2

[0037] Example 2, a functional zinc-rich nitrogen-fixing biological fertilizer, including the following components in parts by mass: zinc-rich minerals: 35%, EM bacteria: 25%, humic acid: 40%.

[0038] Zinc-rich minerals are calcined at 1600-1800°C. After calcination, harmful heavy metals are removed by extraction. EM bacteria are added to the extracted minerals and fermented for 8 days. After the fermentation, zinc and organic matter are activated. neutral minerals, grind the neutral minerals to a particle size of 50 mesh, add humic acid, mix evenly, and obtain functional zinc-rich nitrogen-fixing biological bacterial fertilizer.

Embodiment 3

[0039] Example 3, a functional zinc-rich nitrogen-fixing biological bacterial fertilizer, including the following components in parts by mass: zinc-rich minerals: 25%, EM bacterial agent: 25%, humic acid: 50%.

[0040] Zinc-rich minerals are calcined at 1600-1800°C. After calcination, harmful heavy metals are removed by extraction, and EM bacteria agent is added to the extracted minerals and fermented for 9 days. After the fermentation, the zinc and organic matter are activated. Grinding the neutral minerals to a particle size of 80 mesh, adding humic acid, and mixing evenly, to obtain a functional zinc-rich nitrogen-fixing biological fertilizer.

Abstract

The invention provides functional zinc-rich and nitrogen-fixation biological bacterial fertilizer, belongs to the technical field of biofertilizer and can solve the problems of pollution caused by fertilizer application as well as low effective utilization rate of existing biofertilizer. The functional zinc-rich and nitrogen-fixation biological bacterial fertilizer comprises components by mass asfollows: 25%-35% of mineral substances with zinc content being 5 mg / kg, 25%-35% of an EM bacteria agent and 40%-50% of humic acid; the zinc-rich mineral substances are calcined at the temperature of 1600-1800 DEG C, harmful heavy metal is removed through extraction after calcination, the EM bacteria agent is added to the extracted mineral substances, fermentation is performed for 7-10 days, neutral mineral substances with activated zinc and organic matter are obtained after the fermentation and are ground, then humic acid is added and mixed uniformly with the neutral mineral substances, and the functional zinc-rich and nitrogen-fixation biological bacterial fertilizer is obtained. According to the biological bacterial fertilizer, zinc absorption of plants can be greatly promoted.

Description

technical field [0001] The invention belongs to the technical field of biological fertilizers, in particular to a functional zinc-rich nitrogen-fixing biological bacterial fertilizer. Background technique [0002] For a long time, the use of chemical fertilizers and pesticides has become commonplace. Most of them use single-acting pesticides or chemical fertilizers. The amount of application is increasing year by year and the effect is becoming less and less obvious. This has brought about well-known problems: food, soil, groundwater, rivers and lakes, The sea and the air are heavily polluted by chemicals. At the same time, the pollution caused by the accumulation of heavy metals in the soil in some areas of our country is also quite serious, causing some cultivated land to be used for planting flowers and grass instead of grain. [0003] In the past ten years, biological fertilizers have been used in more and more ways. However, the use of bio-fertilizers is still very si...
