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
The invention belongs to crop Water soluble fertilizer technical field, be specifically related to a kind of urea-ammonium nitrate Water soluble fertilizer.
Background technology
Some problems that water-soluble fertilizer brings while fast development also should the understanding of rationality, and China's water-soluble fertilizer has producing, selling and uying the subject matter existed in process:
(1) meeting that has in storage process of liquid-type foliar nutrient produces flatulence and precipitation, fertilizer can be caused like this to flow out produce pollutions to wait harm, and produces in storage process and precipitate, and the impact such as to make troubles to use;
(2) fill a prescription single, unreasonable: higher economic interests are pursued to reduce production cost by some enterprises, the formula of product does not follow the nutrient uptake feature of crop, just by physics mixture random for the raw material of solubility, or with reference to the formula that oneself registers, the kind of nutrient and ratio not science, the quality of product can not be guaranteed;
(3) market product is chaotic, and qualification rate is low: the producer producing liquid fertilizer increases gradually, and product effect is uneven, and in recent years, although conforming product rate is significantly improved relatively, qualification rate absolute value is still not high;
(4) to apply fertilizer not science, peasant lacks about the consciousness of water-soluble fertilizer: most of peasant does not understand how to go use or seldom use water-soluble fertilizer, let alone apply fertilizers scientifically, even occur that improper use causes and burn seedling bad phenomenon, thus reduce the economic benefit of water-soluble fertilizer;
(5) in liquid-type macroelement water-soluble fertilizer, potassium content is generally on the low side.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of urea-ammonium nitrate Water soluble fertilizer and preparation method thereof.
Present invention process is as Fig. 1, urea soln in urea plant after treater process by urine pump in proportion demand be transported to mixing reactor, ammonium nitrate solution from ammonium nitrate device enters anti-crystallization by ammonium nitrate solution transferpump after the process of ammonium nitrate solution treater, then, after batching regulates serial-connection system adjustment proportioning, mixing reactor is entered.Urea soln and ammonium nitrate solution are delivered in mixing reactor by given proportioning, and by pH-meter adjustment product pH in indication range, then enter finished product treater through finished product transferpump, finally deliver to finished product storage tank.
Technical scheme of the present invention is as follows:
Table 1 raw material specification
