Background technology
Nitrogenous fertilizer is the fertilizer variety that in agriculture production, requirement is maximum, and it is to raising crop yield, and the quality improving agricultural-food plays an important role.Related data display in recent years, China's utilization rate of nitrogen fertilizer is only 30-35%, except part residues in soil, other then lose because of volatilization (ammonium nitrogen) and leaching loss (nitric nitrogen) and nitration and opposite nitration, therefore, how improving utilization rate of nitrogen fertilizer is fertilizer industry investigator problems faced always.Humic acids is a kind of natural organic high-molecular compound, its basic structure is aromatic ring and alicyclic ring, ring is connected with the functional groups such as carboxyl, hydroxyl, carbonyl, quinonyl, methoxyl group, also has the free radical of some amount, effectively can not only suppress soil urease liveness, delay fertilizer deenergized period, plant growth can also be stimulated, improve agricultural product quality; Boron, zinc, molybdenum etc. are the necessary trace elements of crop, have irreplaceable effect in growing process; The plant-growth regulator such as sodium nitrophenolate, have widespread use in foliage fertilizer, punching fertilising and base manure.In the work putting forth effort development of new, increment fertilizer, how these materials and fertilizer to be organically combined is then a significant problem.
Summary of the invention
The object of the invention is the feature for nitrogen fertilizer use, provide a kind of nitrogen fertilizer potentiating agent and application method thereof of nutrient efficient, this synergistic agent is used for, in formulation fertilizer containing nitrogen, can significantly improving utilization rate of nitrogen fertilizer, and then realizing the volume increase of farm crop.
For achieving the above object, the present invention adopts following scheme:
A nitrogen fertilizer potentiating agent for nutrient efficient, comprises following component (by weight): zinc sulfate 10-60, four water eight Sodium Tetraborate 15-45, humic acids 100-500 (powdery), beta-cyclodextrin 5-20, growth regulator 1-5, ammonium chloride 1-5, Resorcinol 1-3, Dyhard RU 100 1-3.
Preparation method: above-mentioned material is got product by after stoichiometry, mixing, pulverizing, screening, drying and processing.
Using method: synergistic agent after treatment can add in the formulation fertilizer containing nitrogen production system of urea, phosphorus ammonium, ammonium chloride, ammonium nitrate, carbon ammonium, make it fully mix with the fused solution of formulation fertilizer containing nitrogen, the granulation mode then through extruding, rolling into a ball ball or whitewashing obtains containing synergistic agent nitrogenous fertilizer; Also can carry out wrapping up or using after mechanically mixing with formulation fertilizer containing nitrogen.Synergistic agent and nitrogenous fertilizer weight ratio are 0.1-0.3:100.
Beneficial effect of the present invention:
Synergistic agent provided by the present invention is practical, obviously can delay nitrogen deenergized period, improves utilization rate of nitrogen fertilizer, supplement the middle and trace element needed for crop, promote crop yield, improve crop quality, realize saving time, saving the fertilising object of power, reduce farmer's burdens, improve agricultural performance.
