Description
Technical field
The present invention relates to enhanced fertilizer, specifically a kind of in ammonium fertilizer or urea blended environmental type Synergistic slow release nitrogen fertilizer and preparation method thereof.
Background technology
Common nitrogen manure fertilizer efficiency period is short, and the fertilizer nitrogen utilization efficiency is low, and quality of agricultural product is not improved.The overall utilization ratio of blood urea nitrogen has only 30～35%; Loss such as the leaching loss of nitrogen, volatilization, rainwash is more; The economic benefit that fertilizer applies is lower, causes the huge waste of resource and the increase of agriculture production cost, produces the pollution in underground water and soil face source simultaneously; Cause the eutrophication of greenhouse gases effect and water body, make the deterioration of the ecological environment.Using in a large number of nitrogenous fertilizer descends quality of agricultural product.For alleviating and addressing these problems, when improving agriculture prodn operation technical supervision, need through improving the self performance of fertilizer; Prolong the effective acting time of fertilizer; Slow down its conversion strength in soil, increase the effective acting time of fertilizer, promote crop effectively absorbing fertilizer; Thereby the utilization ratio of raising utilization rate of fertilizer, particularly nitrogenous fertilizer.
The production of industry at present all is instant fertilizer with ammonium fertilizer, common urea that agricultural is used, and dissolving transforms very fast in water and soil earth.Be converted into ammonium nitrogen very soon under the urase effect after urea is manured into soil in soil, a large amount of ammonium nitrogens is that soil pH value raises rapidly, and ammonia volatilization increases; In the good soil of aeration status; Issue caliche in the effect of soil nitrification bacterium and turn usefulness into; Ammonium nitrogen just is converted into nitrite nitrogen and nitric nitrogen in a short period of time, nitric nitrogen leaching loss very easily in soil, and nitrite nitrogen also can be gaseous loss with the form of nitrogen oxides; Cause a large amount of losses of fertilizer nitrogen, thereby reduced the utilization ratio of fertilizer nitrogen.
Prior art shows; At normal temperatures; After ammonium nitrogen was converted into nitric nitrogen, very soon by leaching loss or be gaseous loss, and nitrification inhibitor Dyhard RU 100 (Dicyandiamide DCD) can effectively suppress the conversion rate of ammonium nitrogen to nitric nitrogen; Prolong the RT of ammonium nitrogen in soil, increase the effective acting time of urea; Fertilizer synergist poly-aspartic-acid ((Polyaspartic acid PASP)) is efficient synergistic agent of a kind of fertilizer and novel plant dietetic alimentation promotor.Plant desired nutritional composition is had extremely strong huge legendary turtle close function, effectively nitrogen in the enrichment soil, phosphorus, potassium and trace element supply the plant absorbing utilization, especially to useful element in the absorption of zinc, iron, three kinds of elements of manganese and the enriching plant root surrounding soil; Effect is the most obvious, has advantages such as long-chain albumen and AS, promotes the absorption of plant to nutritive element; Promote the growth of root system; Healthy and strong plant strengthens resistance, improves quality; Can be used as good plant nutrient promotor, growth substance, seed soaking agent, foliage fertilizer, water retention agent, and have do not contain hormone, nontoxic, used characteristics such as noresidue; PASP is different from plant hormone, has that consumption is little, the high antiviral characteristics.
With DCD with process the fertilizer composite synergist after PASP combines through high-tech and can effectively prolong ammonium fertilizer or amide nitrogen fertilizer fertilizer efficiency period; Improve crop absorption of nitrogen is utilized effect; Increase plant to the absorption of nitrogen amount, improve fertilizer utilization ratio, increase concentrations of nutrient such as protein, amino acid and fat in the agricultural-food; Increase the effective enriching quantity of the required trace element of crop in soil simultaneously, promote the absorption of crop other nutritive element.
Summary of the invention
