Problems solved by technology

However, with the wide application of chemical fertilizers, environmental problems are becoming more and more serious. The chemical components contained in chemical fertilizers change the soil structure and pollute water sources. Traditional farmyard manures are not suitable for modern large-scale production. Therefore, combining chemical fertilizers with The advantage of farm manure is that organic-inorganic compound fertilizer is derived, and the application number is CN200910133810.3, which discloses a compound fertilizer production method, which comprises the following steps: setting the nutrient distribution ratio of the required compound fertilizer; using packaging The fertilizer raw materials in bags or containers are directly used as the feeding device of the compound fertilizer production equipment; the compound fertilizer production equipment includes a silo platform, a movable hopper, and a mixer, and the silo platform is equipped with a discharge port. The fertilizer in the packaging bag enters the movable hopper below the outlet of the silo platform through the outlet of the silo platform, and the fertilizer in the movable hopper is sent to the agitator for stirring and then discharged by the agitator The discharge port of the compound fertilizer production equipment obtains the compound fertilizer that meets the requirements. The invention can prepare the compound fertilizer according to the user's soil condition and crop demand, so it has strong pertinence, good quality and balanced nutrition. However, while the compound fertilizer exerts excellent effects, it also has some problems, such as short fertilizer effect time, poor soil aeration, weak water adsorption capacity, etc.

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...

Abstract

The invention discloses a compound fertilizer production technology. The technology comprises the following steps: (1) selecting organic raw materials, namely by weight percent, respectively selecting 35-45% of crop straws, 25%-30% of pig manure and 25%-40% of organic household garbage as the raw materials, wherein the organic household garbage comprises 55wt% of leftover, 15wt% of fruit peels and 30wt% of waste paper; (2) crushing and drying; (3) preparing inorganic fertilizer, namely fully mixing and stirring ordinary superphosphate, urea and potassium chloride, then adding zeolite powder and pulverized fuel ash, and continuously and uniformly mixing, wherein the mass ratio of the superphosphate, the urea and the potassium chloride is (1-2):1:(1-1.5), and the usage amounts of the zeolite powder and the pulverized fuel ash respectively account for 5-8% and 3-5%; (4) metering and mixing; (5) granulating the fertilizer; (6) packaging a product, namely packaging the produced granulated fertilizer with a polypropylene woven bag with a lining, wherein each bag contains 20-25Kg of the fertilizer, and putting the packaged fertilizer in a cool, dry and ventilated storehouse to store. The technology is reasonable and simple, and the raw materials can be widely obtained; in addition, the fertilizer can make the soil bulked, so that the air permeability of the soil is increased; moreover, the fertilizer has a long fertilizer effect period and strong water adsorption capability.

Description

technical field [0001] The manufacturing process of the agricultural chemical fertilizer that the present invention relates to, particularly relates to a kind of compound fertilizer production process. Background technique [0002] At present, chemical fertilizers have been widely used in the field of agricultural production. Because it can increase the output of agricultural products and improve the soil structure, chemical fertilizers have become necessary fertilizers for various crops. With the development of agriculture, especially the emergence of large-scale contracted farmland, the demand for chemical fertilizers is increasing day by day. However, with the wide application of chemical fertilizers, environmental problems are becoming more and more serious. The chemical components contained in chemical fertilizers change the soil structure and pollute water sources. Traditional farmyard manures are not suitable for modern large-scale production. Therefore, combining che...
