Nitrogen fertilizer high-molecular composite synergist, and preparation method thereof

Abstract

The invention relates to a chemical fertilizer synergist, and especially relates to a nitrogen fertilizer high-molecular composite synergist and a preparation method thereof. The synergist comprises, by weight: 1-1.5parts of high-water-absorption resin, 6-10 parts of zeolite, and 0.5-0.8 parts of potassium humate. The method comprises the steps that: the high-water-absorption resin, zeolite, and potassium humate are screened; the high-water-absorption resin, zeolite, and potassium humate are bake-dried; the materials are well mixed; and the synergist is mixed with a nitrogen fertilizer with a ratio that the synergist to pure nitrogen fertilizer is 1:1-1.4. The synergist provided by the invention has the advantages that: with the synergist, an absorption effect is provided, nitrogen fertilizer release speed can be regulated, nitrogen fertilizer utilization rate can be improved, soil aggregate structure can be ameliorated, plant water-fertilizer absorption can be promoted, plant growth can be promoted, and the synergist can be repeatedly utilized. With the synergist, nitrogen fertilizer utilization rate of plant can be improved, peasant burden can be reduced, and environment pollution caused by nitrogen fertilizer loss can be reduced. With the synergist, agricultural production improvement, fertilizer saving, and environment protection can be combined.

Description

technical field [0001] The invention relates to a nitrogen fertilizer synergist, in particular to a nitrogen fertilizer polymer composite synergist and a preparation method thereof. Background technique [0002] Serious drought and water shortage have always been an important factor restricting the economic and social development of our country, especially in the arid and semi-arid areas of Northwest my country. As a large agricultural country, my country's current agricultural water consumption accounts for about 70% of the country's total water consumption, but the agricultural water production efficiency is less than 1.0kg / m 3 . At the same time, my country began to use a large amount of nitrogen fertilizers in the early 1970s, and has become the largest nitrogen fertilizer consumer in the world. While the crop yield has increased significantly, the application of excessive nitrogen fertilizers and only 30% to 35% of nitrogen fertilizer use efficiency have led to eutrop...

Problems solved by technology

However, in the application process of these materials, there are still problems such as high cost, complicated production and preparation process, and the inability of the enhancer itself to improve the soil nutrient environment.
