Abstract

The invention relates to a multifunctional synergistic nitrogen fertilizer and a preparation method thereof, and is applied in the field of agriculture and forestry production. The product comprises medium trace elements, a plant nutrition conditioner and a nitrogen fertilizer synergist. The product is rich in the medium trace elements, such as calcium, magnesium, sulfur, boron, manganese, zinc and the like, required by crop growth and guarantees full absorption of crop nutrition. The plant nutrition conditioner and the nitrogen fertilizer synergist can effectively promote plants to absorb nutrient elements and improve the utilization ratio of the nitrogen fertilizer. The multifunctional synergistic nitrogen fertilizer is prepared by the following steps: mixing urea, ammonium sulfate, ammonium chloride, bentonite, zinc sulfate, manganese sulfate, calcium chloride, magnesium sulfate, disodium octoborate tetrahydrate and the like according to a certain scientific ratio; adding a certain dose of plant nutrition conditioner and the nitrogen fertilizer synergist; mixing completely; and pelletizing. The multifunctional synergistic nitrogen fertilizer can prolong the useful life of the nitrogen fertilizer by 90 to 120 days, increases the utilization ratio of the nitrogen fertilizer by over 30 percent, increases yield by 15 to 20 percent, and enhances resistance, such as drought resistance, cold resistance, disease resistance and the like, of crops.

Description

technical field [0001] The invention relates to a multifunctional synergistic nitrogen fertilizer, in particular to an environment-friendly multifunctional synergistic nitrogen fertilizer mixed with ammonium nitrogen fertilizer and urea and a preparation method thereof. Background technique [0002] Traditional nitrogen fertilizer has the characteristics of easy leaching and volatilization, so the fertilizer effect period of nitrogen fertilizer is short and the fertilizer utilization rate is low. The data show that the seasonal utilization rate of nitrogen fertilizer in developed countries is 60-70%, the world average is 45-55%, while our country is only 25%-33%. A large amount of nitrogen fertilizer lost pollutes soil, groundwater and the atmosphere, thereby affecting people's lives, and also causing a huge waste of resources and an increase in agricultural costs. Extensive application of nitrogen fertilizers has also led to a decline in the quality of agricultural product...
