Abstract

The invention discloses an organic fertilizer applied to crops and relates to the technical field of chemical fertilizers. The organic fertilizer applied to the crops is prepared from the following raw materials: 20-30 parts of leonardite, 20-30 parts of organic matters, 18-25 parts of rotten and fermentative silkworm excrement, 2-4 parts of gluconic acid, 10-15 parts of carbamide and 0.1-1 part of trace elements. A method for preparing the organic fertilizer applied to crops comprises the following steps: firstly preparing the rotten and fermentative silkworm excrement; then putting the leonardite and gluconic acid in water to react; and finally, uniformly mixing with carbamide, the trace elements and the organic matters to prepare the organic fertilizer. The organic fertilizer is capable of providing comprehensive nutrition for the crops, improving the fertilizer efficiency, increasing and updating the organic matters in soil, promoting reproduction of microorganisms, greatly improving the nutrition conversion rate of the cultivation material, improving the biochemistry activity of the soil, promoting photosynthesis of chlorophyll of the crops, shortening the growth periods of the crops, reducing plant diseases and insect pests and improving the yield of crops.

Example Embodiment

[0020] Example 1:

[0021] This crop organic fertilizer is made from the following quality raw materials:

[0022] Weathered lignite 100Kg, organic matter 100Kg, decomposed and fermented silkworm excrement 90Kg, gluconic acid 10Kg, urea 50Kg, trace element 0.5Kg, trace element contains zinc 0.2Kg, iron 0.15Kg, boron 0.05Kg, copper 0.1Kg;

[0023] The preparation method is:

[0024] A. Preparation of decomposed and fermented silkworm excrement: Spread the silkworm manure flat on the ground with a thickness of 18-20 cm; mix 20% oligosaccharides and dry yeast at a ratio of 300:1 and stir to obtain fermentation. Spray the fermentation broth on the spread silkworm excrement until the silkworm excrement is completely wet, and then cover it with a plastic film for fermentation. After 20 days of fermentation, open the film and turn the pile, and then cover the pile and continue fermentation for 15 days. , That is;

[0025] B. Add 100Kg of weathered lignite and 10Kg of gluconic acid into a reactor filled with 200Kg of water, stir evenly, and proceed with the reaction. The reaction temperature is kept at 25°C;

[0026] C. After the reaction time of step B reaches 2 hours, mix with 50Kg of urea, 0.5Kg of trace elements, and 100Kg of organic matter, then add it to the 90Kg of decomposed and fermented silkworm excrement obtained in step A, granulate, and dry to obtain this crop organic fertilizer.

Example Embodiment

[0027] Example 2

[0028] This crop organic fertilizer is made from the following quality raw materials:

[0029] Weathered lignite 150Kg, organic matter 150Kg, decomposed and fermented silkworm excrement 125Kg, gluconic acid 20Kg, urea 75Kg, trace element 5Kg, trace element contains zinc 2Kg, iron 1.5Kg, boron 0.5Kg, copper 1Kg;

[0030] The preparation method is:

[0031] A. Preparation of decomposed and fermented silkworm excrement: Spread the silkworm manure flat on the ground with a thickness of 18-20 cm; mix 20% oligosaccharides and dry yeast at a ratio of 300:1 and stir to obtain fermentation. Spray the fermentation broth on the spread silkworm excrement until the silkworm excrement is completely wet, and then cover it with a plastic film for fermentation. After 20 days of fermentation, open the film and turn the pile, and then cover the pile and continue fermentation for 15 days. , That is;

[0032] B. Add 150Kg of weathered lignite and 20Kg of gluconic acid into a reactor filled with 250Kg of water, stir evenly, and proceed with the reaction, keeping the reaction temperature at 25°C;

[0033] C. After the reaction time of step B reaches 2 hours, mix with 75Kg of urea, 5Kg of trace elements, and 150Kg of organic matter, then add to the 125Kg of decomposed and fermented silkworm excrement obtained in step A, granulate, and dry to obtain organic fertilizer for this crop .
