Problems solved by technology

Therefore, organic fertilizer is an important fertilizer source, and the existing organic compost either has only about 6% nutrients or high phosphorus content, and the high phosphorus content is mainly organic fertilizer with high phosphorus content, which is mainly obtained by adding A large amount of phosphate-containing rock powder is used to increase the phosphorus content, and its potassium content is low; currently there is little or no potassium-rich organic fertilizer

Embodiment 1

[0014] 423 kg of dry chicken manure (water content 35%), wet chicken manure 1000 kg (water content 65%); 330 kg of edible mushroom residue (water content 45%); 1973 kg), add 1.98 kg of VT-200 composite bacterial agent, after two days, the temperature rises to 70 ° C, continue to turn and throw aerobic fermentation every day, until the 10th day, the temperature does not rise but begins to decline steadily, adding tobacco rod powder (organic matter 58.13 %, Potassium 7.26%, Nitrogen 1.51%, Phosphorus 0.75%) 400 kg, stir twice to mix, the temperature drops and then rises, stir once a day, after 7 days, the temperature begins to drop steadily, the fermentation enters post-ripening, and the color of the fertilizer turns brown brown. It is a mature organic fertilizer, its nutrient content is nitrogen 2.7%, phosphorus 3.5%, potassium 4.5%, total nutrient 10.7%, and organic matter content is 38.5%.

Embodiment 2

[0016] Dry chicken manure 850 kg (moisture content 35%), edible mushroom residue 340 kg (water content 45%); sawdust 250 kg (water content 35%), add water 200 kg, mix evenly (total weight 1640 kg), add VT- 1.6 kilograms of 200 compound bacterial agents, after two days, the temperature rose to 70°C, and continued to turn and throw aerobic fermentation every day, and the temperature no longer rose to the 10th day but began to decline steadily, adding tobacco rod powder (organic matter 61.0%, potassium 7.26%, nitrogen 1.71%, phosphorus 0.75%) 800 kilograms, stir twice to mix, the temperature rises again after falling, stir once a day, after 7 days, the temperature begins to drop steadily, the fermentation enters post-ripening, and the color of the fertilizer turns brown. It is a mature organic fertilizer, its nutrient content is 2.9% nitrogen, 2.9% phosphorus, 5.1% potassium, 10.9% total nutrient, and 39.5% organic matter.

Embodiment 3

[0017] Embodiment 3: 400 kilograms (moisture content 35%) of dry chicken manure, 1000 kilograms (moisture content 65%) of wet chicken manure; 300 kilograms (water content 45%) of edible fungus slag; Mix (total weight 1950 kg), add 1.95 kg of VT-200 composite bacterial agent, after two days, the temperature rises to 70°C, continue to turn and throw aerobic fermentation every day, until the 10th day, the temperature does not rise but begins to decline steadily, add tobacco rods Flour (organic matter 59.3%, potassium 6.6%, nitrogen 1.23%, phosphorus 0.73%) 500 kg, stir twice to mix, the temperature drops and then rises, stir once a day, after 7 days, the temperature begins to decline steadily, and the fermentation enters post-ripening. The color becomes tan. That is mature organic fertilizer, its nutrient content is nitrogen 2.7%, phosphorus 3.4%, potassium 4.8%, total nutrient 10.9%, and organic matter content is 38.8%.

Abstract

The invention discloses a K-rich organic fertilizer and a production method thereof. The K-rich organic fertilizer is prepared by following steps: taking the mixture of chicken manure, residue of edible fungi and filings as raw material; turning over piles at 55-75 DEG C under the effect of VT-200 compound microbial inoculums and aerobically fermenting for 8-10 days; and then adding K-rich tobacco stalk powders, and continuously turning over piles for aerobically ferment for 10-15 days to obtain the K-rich organic fertilizer. The product comprises various effective components according to the weight percent: more than 10.0 percent of total nutrient, 2.6-3.3 percent of nitrogen, 2.8-3.5 percent of phosphorus and 4.5-5.1 percent of potassium. The total nutrient of the nitrogen, the phosphorus and the potassium is more than or equal to 10 percent, wherein the content of the potassium reaches more than 4.5 percent and is equivalent to 1.5-2.5 times of the content of the potassium in common organic fertilizer. The vegetable organic potassium is not easy to loss, and can be slowly released, thereby greatly improving the utilization ratio, reducing the application of inorganic K fertilizer, and achieving the effects of increasing the production and saving resources.

Description

technical field [0001] The invention relates to a potassium-rich organic fertilizer and a production method thereof. Background technique [0002] At present, chemical fertilizers are still mainly used for fertilization in rural areas of our country, but among the three elements of nitrogen, phosphorus, and potassium in chemical fertilizers, potassium is highly soluble in water and is easy to lose, resulting in low utilization rate of potassium in fertilizers; more importantly, long-term large quantities of chemical fertilizers The input and unreasonable use will lead to changes in soil physical and chemical properties, such as soil compaction, and cause soil health degradation and soil-borne diseases to increase; in addition, it will also lead to a decrease in the total amount of soil microorganisms and beneficial organisms. Tests have shown that the total amount of microorganisms on the land where conventional chemical fertilizers and pesticides are used is more than 50% l...
