Compound fertilizer production technology

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...

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.
