Embodiment 1
[0018] A kind of compound fertilizer production technique of the present embodiment is characterized in that, its processing step is as follows:
[0019] (1) Selection of organic raw materials; by weight percentage, 35-45% of crop straw, 25%-30% of pig manure, and 25-40% of organic domestic waste are selected as raw materials, and the organic domestic waste includes leftovers, fruit peels and Waste paper, of which, by weight percentage, leftovers are 55%, fruit peels are 15%, and waste paper is 30%;
[0020] (2) Grinding and drying: Grinding and mixing the organic raw materials selected in step (1), adding deodorant solution, deodorizing for 3~5min, adding active silica gel, putting it in a centrifuge for centrifugal dehydration for 3~5min, and then performing cyclone drying , and the drying temperature is 80~100°C to make organic fertilizer;
[0021] (3) Inorganic fertilizer preparation; fully mix and stir ordinary calcium superphosphate, urea and potassium chloride, then ad...
Embodiment 2
[0026] Embodiment 2: the rest is the same as the above-mentioned embodiment 1, the difference is that certain ingredients are removed from the inorganic nutrition prepared in step (3) to meet the specific needs of different plants. In this embodiment, the cost is relatively low, But the scope of application is narrow.
Embodiment 3
[0027] Example 3: The rest are the same as in Example 1, the difference is that in step (4), the ratio of organic and inorganic raw materials is changed to 2:1. In this example, the organic nutrition is high, and the plants receive more nutrition. However, it is difficult for plants to absorb it.
[0028] The invention completes the production process of organic-inorganic compound fertilizer through six steps of organic raw material selection, crushing and drying, inorganic fertilizer preparation, metering and mixing, fertilizer granulation and product packaging. The source of raw materials is wide, and at the same time, it can bulk up the soil and increase the ventilation of the soil. In addition, the fertilizer effect time is long and the moisture absorption capacity is strong. In the selection of organic raw materials, domestic waste has a wide range of sources, and the daily output is large, which meets the requirements of fertilizer production and effectively solves the pr...
