How to use cow dung manure fertilizer equipment production
Cattle excretion of cattle breed, age, weight, raising management condition and there are differences, different according to the check, cattle emissions an average of 8703 kg, is that every pig breeding period excretion of 3.8 times.National cow urine volume can reach 1.07324 billion t accounted for 34.10% of total manure resources, second only to the pig urine resources, putting it in second spot.According to cow urine nutrient content, each cow's faeces and urine can provide 1 year of 38.0 kg nitrogen, phosphorus removal and 5.3 kg, 47.6 kg potassium, the cow urine resources provided by nitrogen, phosphorus and potassium, respectively, 4.701 million t, 629000 t, 5.855 million t, total 11.185 million t, equivalent to 33.71% of the total national investment fields of inorganic nutrients, at the same time also can provide thick 99.687 million t of organic compounds;Copper, zinc, iron, manganese, boron, molybdenum 656000 t.The nutrition element such as calcium, magnesium, sulfur, silicon 25.45 million t.
Quality evaluationCow urine composition is similar to pig urine, mainly of cellulose, hemicellulose and protein and its decomposition product and all kinds of inorganic salt.Cow is a ruminant feed after repeated chewing, fine quality, the dung and water, high water content in fecal, air to flow, difficult to decompose the organic matter in manure, rotten slower, cold organic fertilizer.After fermentation, without applied rotten cow urine low, rotten, can improve the effectiveness.Application of cow urine can cause the soil loose, easy cultivation, improvement of clay has a good effect.According to the national organic fertilizer quality classification standard, divided into cow dung category, the nutrient content of medium.
Fresh cow dung average total nitrogen content is 0.38%, total phosphorus, total potassium, 0.10% and 0.23%, 75.0% moisture content, crude organic matter 7.1% 14.9%, crude ash powder, C/N23.2, PH7.9-8.0;Average content of various trace elements: copper zinc 5.7 mg/kg, 22.6 mg/kg and 943 mg/kg of iron, manganese, 139 mg/kg, 3.2 mg/kg, mo 0.30 mg/kg;Chlorine, sodium, calcium, magnesium, sulfur, the average content of silicon is respectively 0.43%, 0.11%, 0.07%, 0.04%, 0.07% and 3.7%.
How to use cow dung processing organic fertilizerCow dung drying or drain in the first place, make its moisture control under 85%, then add in the end of the straw, ratio of 7:3, the raw material (cow) accessories (straw) at the end of the carbon ratio control in 23 ~ 28, moisture content control in 52% ~ 68%.Finally, add the organic manure fermentation agent of rotten.
Raw materials and auxiliary materials and bacteria agent, can be on the heap fermentation, the requirement of the heap is mixture on the fermentation field into bottom 1.8 meters to 3 meters wide, 0.8 meters wide above ~ 1 m, 1 m to 1.5 m high of trapezoidal buttress, the crib between 0.5 meters.After a crib heap, in 24 to 48 hours the temperature will rise to more than 60 degrees, to keep temperature for 48 hours to start over.
Turn the heap is sure to uniform thoroughly, will lower material as far as possible into the heap in the upper, so as to fully decomposed.After first time turns mow, later will turn heap every week.However, when the temperature over 70 degrees, must immediately turn heap, or beneficial microorganism and fermentation bacteria can be killed in great quantities, is not conducive to rotten fermentation.
All standard of rotten fermentation
a is to see color, the color of general fertilizer will become brown or dark brown, ammonium nitrogen content significantly increased.
the second is the leaching liquid, rotten organic fertilizer and water (1:5) after mixing, placed leach liquor color 5 minutes.
three is to look at the volume, the volume of finished compost, than just of 1/3 ~ 1/2 pile collapse.Finally, the fermentation of organic fertilizer evenly on the drying field unfold, the thickness of not more than 20 centimeters, and often make water content below 32%.
