Abstract
The invention relates to a compound fertilizer, and the compound fertilizer comprises, by weight (percentage) ratio: 20% of urea, 33% of monoammonium phosphate, 8% of potassium chloride, 32.5% of ammonium chloride and 8% of attapulgite, wherein the accuracy of the above components is of plus or minus 5%. The compound fertilizer is rich in phosphorus, free of pollution, lodging-resistant, frost-resistant, and pest-resistant, and can adjust soil compaction, adjust the pH value of the soil, protect the soil moisture, and improve crop yields and product quality; and the effective granulation rate of the compound fertilizer can be improved, reducing production cost thereof, and the production process is simple, so the compound fertilizer is easy for popularization.
Description
Technical field
The present invention relates to a kind of agricultural-food dedicated fertilizer, specifically a kind of composite fertilizer that contains attapulgite, is rich in phosphoric.
Background technology
At present, the composite fertilizer kind is a lot, but these composite fertilizers all can not effectively be improved hardening due to the soil that single fertilizer is caused, can not effectively regulate the potential of hydrogen of soil, can not make farm crop improve production output and quality product, brought loss greatly for the good harvest of agricultural, and people healthy caused certain harm.In addition in compound fertilizer pelletizing technique, the common clay mineral are as binding agent, carrier and amendment.Because most of compound fertilizer factories are determined mostly by rule of thumb to kind and the ratio of clay mineral used, so not high unsettled phenomenon usually appears in effective granulating rate of its Chemical Mixed Fertilizer, cause returning charge too many, had a strong impact on the production cost of Chemical Mixed Fertilizer.Therefore research and develop that granulating rate is high, the potential of hydrogen that can regulate soil, the moisture of soil protection, composite fertilizer resistant to lodging, freeze proof, disease and insect resistance be very necessary.
Summary of the invention
In order to solve existing chemical fertilizer existing problem in processing and application.The purpose of this invention is to provide a kind of composite fertilizer; the employing china natural resources is abundant, reserves are large; widespread attapulgite, thus effective granulating rate of raising Chemical Mixed Fertilizer reduces its production cost; to overcome existing weak point in existing compound fertilizer pelletizing technique; be rich in addition phosphoric, pollution-free, can regulate soil compaction; the potential of hydrogen of soil, the moisture of soil protection, resistant to lodging, freeze proof, disease and insect resistance can be regulated, crop yield and quality product can be improved.
Composite fertilizer of the present invention, (per-cent meter) proportioning is by weight: urea 20%, monoammonium phosphate 33%, Repone K 8%, ammonium chloride 32.5%, attapulgite 8%; The tolerance range of above composition is positive and negative 5%.
Attapulgite is as composite fertilizer's binding agent, and the granulating and forming rate is high, and the time is short, and institute's granule strength of making is high, and surface smoothness is good, and the fertilizer conservation time is long, can improve throughput, reduces power consumption, can also save the consumption of the high price raw materials such as talcum powder, ammonium chloride.
The monoammonium phosphate that composite fertilizer of the present invention is rich in is a kind of water soluble quick-acting composite fertilizer, and the ratio of available phosphorus and total nitrogen content is 5.44:1 approximately, is one of principal item of high-concentration phosphate compound fertilizers.Monoammonium phosphate is widely used in various food crop and the cash crop such as paddy rice, wheat, corn, Chinese sorghum, cotton, melon and fruit, vegetables, can provide efficiently crop required nutrient.
Composite fertilizer of the present invention can adopt the mixing granulation method to make.Through material choice, determine the ratio of each element, calculate the weight of each raw material, the technical process such as pulverizing, ammonification, mixing, granulation, quality examination, packing obtain composite fertilizer of the present invention.
The invention has the beneficial effects as follows: this composite fertilizer; be rich in phosphoric; pollution-free; can regulate soil compaction, regulate the potential of hydrogen of soil, the moisture of soil protection, resistant to lodging, freeze proof, disease and insect resistance, can improve crop yield and quality product; can improve effective granulating rate of Chemical Mixed Fertilizer; reduce its production cost, manufacture craft is simple, easily promotes.
Embodiment
Embodiment 1
This composite fertilizer is by weight percentage with 20% urea, 33% monoammonium phosphate, 8% Repone K, 32.5% ammonium chloride, 8% attapulgite was through pulverizing the 120-150 mesh sieve, putting into stirrer fully mixed it in 20 minutes, bring the disk steam granulation into by conveying, cause grain to enter dryer and dry, more cooling through cooler, then screen through screen-dividing machine, then send into polishing machine and carry out polishing and be shaped as round shape 2.5-4.5 millimeter, finished product, metering packing.
This composite fertilizer granulating rate improves 10%, after being used in the soybean experiment field of 3 mu, compares with using common fertilizer, and soybean yields improves 24%, and quality of agricultural product also improves, and fertile soil power increases.
Embodiment 2
This composite fertilizer (kilogram) is by weight counted 20 kilograms, urea, 33 kilograms of monoammonium phosphates, 8 kilograms, Repone K, 32.5 kilograms of ammonium chlorides, 8 kilograms of attapulgites were through pulverizing the 120-150 mesh sieve, putting into stirrer fully mixed it in 20 minutes, bring the disk steam granulation into by conveying, cause grain to enter dryer and dry, more cooling through cooler, then screen through screen-dividing machine, then send into polishing machine and carry out polishing and be shaped as round shape 2.5-4.5 millimeter, finished product, metering packing.
This contains the composite fertilizer granulating rate and improves 11%, after being used in the wheat experiment field of 2 mu, compares with using common fertilizer, and wheat yield improves 24%, and quality of agricultural product also improves, and fertile soil power increases.
