Embodiment 1

[0037] The present embodiment provides a kind of micro-nano carbon long-acting environment-friendly compound magnetic fertilizer. In 2014, a corn fertilizer experiment was carried out at the Liaoning Provincial Soil and Fertilizer General Station. The composition of the compound magnetic fertilizer according to the weight percentage is: micro-nano carbon 0.03%, magnetic Iron slag powder 1.5%, humic acid 15%, ammonium bicarbonate 3.3%, rare earth 0.25%, catechol 0.02%, nano silicon powder 1.5%, the rest is chemical fertilizer, and the element content is: nitrogen 14%, phosphorus 5.2%, potassium 14%, calcium 1.2%, magnesium 0.7%, zinc 0.6%, manganese 0.6%, iron 0.4%, copper 0.4%, boron 0.3%.

[0038] Use 50 kilograms of micro-nano carbon long-term environmental protection compound magnetic fertilizer per mu (the application rate of conventional fertilizer is 66.7 kilograms). After application, the yield per mu is 797.32 kg, which is 757.46 kg per mu compared with commercially av...

Embodiment 2

[0040] The present embodiment provides a kind of micro-nano carbon long-acting environment-friendly compound magnetic fertilizer. In 2014, a rice fertilizer effect experiment was carried out at Liaoning Provincial Soil and Fertilizer General Station. The composition of the compound magnetic fertilizer according to the weight percentage is: micro-nano carbon 0.03%, magnetic Iron slag powder 1.5%, humic acid 15%, ammonium bicarbonate 3.3%, rare earth 0.25%, catechol 0.02%, nano silicon powder 1.5%, the rest is chemical fertilizer, and the element content is: nitrogen 14%, phosphorus 5.2%, potassium 14%, calcium 1.2%, magnesium 0.7%, zinc 0.6%, manganese 0.6%, iron 0.4%, copper 0.4%, boron 0.3%.

[0041] Apply 40 kilograms of micro-nano carbon long-term environmental protection compound magnetic fertilizer per mu (the application rate of conventional fertilizer is 27.3 kilograms). After application, the yield per mu is 683.96 kg, which is 649.23 kg per mu compared with commercial...

Embodiment 3

[0043] This embodiment provides a kind of micro-nano carbon long-term environment-friendly compound magnetic fertilizer. In 2018, a rice fertilizer effect experiment was carried out at Wutonghe Farm in Heilongjiang. The composition of the compound magnetic fertilizer according to the weight percentage is: micro-nano carbon 0.04%, magnetic iron Slag powder 1.1%, humic acid 13%, ammonium bicarbonate 3.8%, rare earth 0.26%, catechol 0.03%, nano silicon powder 1.6%, the rest is chemical fertilizer, and the element content is: nitrogen 15%, phosphorus 5.2 %, Potassium 14%, Calcium 1.6%, Magnesium 0.82%, Zinc 0.65%, Manganese 0.61%, Iron 0.4%, Copper 0.4%, Boron 0.3%.

[0044] Apply 360 kg of micro-nano carbon long-term environmental protection compound magnetic fertilizer per hectare (the application rate of conventional fertilizer is 500 kg). After application, the yield per hectare is 8,800 kilograms, compared with 8,033 kilograms per hectare of commercially available conventiona...

Abstract

The invention relates to a micro-nano carbon long-lasting environment-friendly mixed magnetic fertilizer which comprises the following components in percentage by weight: 0.03-0.05% of micro-nano carbon, 1-1.5% of magnetic iron-ore slag powder, 11-15% of humic acid, 2.8-4.2% of ammonium bicarbonate, 0.1-0.3% of rare earth, 0.01-0.07% of catechol, 1.5-1.7% of nanometer silicon powder and the balance of a chemical fertilizer, wherein the chemical fertilizer comprises nitrogen, phosphorus, potassium, calcium, magnesium, zinc, manganese, iron, copper and boron. According to crops, 20-50kg of the mixed magnetic fertilizer is applied to each mu of farmlands. The mixed magnetic fertilizer is tested in cereal crops such as corn, wheat, rice and various coarse cereals and economic crops such as cotton, watermelons, sweet melons and vegetables, the yield increase is high, the per unit yield of field crops is increased by 5-15%, the per unit yield of vegetable crops is increased by 20-40%, and fertilizers can be saved by 20-30%.

Description

technical field [0001] The invention belongs to the technical field of fertilizer preparation, and in particular relates to a micro-nano carbon long-acting environment-friendly compound magnetic fertilizer and a preparation method and application thereof. Background technique [0002] In the past two decades, the fertilization of field crops (such as: rice, corn, etc.) in my country and the rapidly developed facility agriculture, as long as it is flush fertilization or soilless cultivation, almost all use purified fertilizers or compound fertilizers, or continue In the chemical farming mode, fertilizer nutrients are not complete, not only the yield of crops is low, but also the taste generally loses its original ecological flavor. [0003] At present, the country has been advocating: reducing chemical fertilizer input, reducing environmental pollution, increasing the absorption of C02 by crops, and reducing greenhouse gas emissions in agricultural production are important for...
