Urea-ammonium nitrate water-soluble fertilizer and preparation method thereof

Abstract

The invention discloses a urea-ammonium nitrate water-soluble fertilizer and a preparation method thereof, and belongs to the technical field of crop water-soluble fertilizers. The urea-ammonium nitrate water-soluble fertilizer adopts ammonium nitrate, urea, water, free ammonia and a corrosion inhibitor as raw materials. The water-soluble fertilizer can be individually applied or can be applied together with other chemical pesticides and fertilizers, has quick acting and long acting effects, greatly widens the absorption and utilization rate of the nitrogen element, and improves the quality of crops; the water-soluble fertilizer contains plant rapid growth factors, and nutrients can rapidly reach root, stem and leaf cell tissues of plants, so the urea-ammonium nitrate water-soluble fertilizer provides rapid and lasting nutrition supply for plants; and the urea-ammonium nitrate water-soluble fertilizer has the water solubility of 100%, has no impurities, has a utilization rate reaching 90% or above, is especially suitable for sprinkling, drip irrigation and foliar fertilization, and has the advantages of water saving, time saving, environmental protection and high efficiency.

Description

technical field [0001] The invention belongs to the technical field of water-soluble fertilizer for crops, and in particular relates to a urea-ammonium nitrate water-soluble fertilizer. Background technique [0002] Some problems brought about by the rapid development of water-soluble fertilizers should also be rationally understood. The main problems in the production, sales and use of water-soluble fertilizers in my country are: [0003] (1) Some liquid foliar fertilizers will produce flatulence and precipitation during the storage process, which will cause pollution and other hazards caused by the outflow of fertilizers, and precipitation will occur during the storage process, which will cause inconvenience to use; [0004] (2) The formula is single and unreasonable: In order to reduce production costs and pursue higher economic benefits, some enterprises do not follow the characteristics of fertilizer requirements of crops in the formula of products, but just randomly ...

AI Technical Summary

Problems solved by technology

[0003] (1) Some liquid foliar fertilizers will produce flatulence and precipitation during the storage process, which will cause pollution and other hazards caused by the outflow of fertilizers, and precipitation will occur during the storage process, which will cause inconvenience to use;

[0004] (2) The formula is single and unreasonable: In order to reduce production costs and pursue higher economic benefits, some enterprises do not follow the characteristics of fertilizer requirements of crops in the formula of products, but just randomly mix soluble raw materials physically, or refer to registered The formula, type and proportion of nutrients are unscientific, and the quality of the product cannot be guaranteed;

[0005] (3) The products in the market are chaotic and the pass rate is low: the number of manufacturers producing liquid fertilizers is gradually increasing, and the product effects are uneven. In recent years, although the product pass rate has relatively improved significantly, the absolute value of the pass rate is still not high;

[0006] (4) Fertilization is unscientific, and farmers lack awareness of water-soluble fertilizers: most farmers do not know how to apply water-soluble fertilizers or rarely use water-soluble fertilizers, let alone scientific fertilization, and even improper use causes bad seedling burning, thereby reducing Economic benefits of water-soluble fertilizers;
