Liquid nitrogen fertilizer

Abstract

The invention provides a liquid nitrogen fertilizer. The liquid nitrogen fertilizer comprises a urea nitramine aqueous solution, magnesium sulfate, ferrous sulfate, rapin, calcium, zinc, boron, silicon, a plant growth regulator, a fertilizer inhibitor and water. The nitrogen fertilizer provided by the invention contains three nitrogen forms: nitro form, ammonium form and amide form, is compatiblewith quick acting and long acting (the lasting period is 45 days), and does not contain the biuret; the liquid nitrogen fertilizer is full in water-soluble nutrient, free from impurity and residue, and the utilization rate is up to 90%; the liquid nitrogen fertilizer can be used for spray-irrigating, drop-irrigating and irrigating the fertilizer, and can be used for foliage spraying.

Description

technical field [0001] The invention relates to the field of agricultural fertilizers, in particular to a liquid nitrogen fertilizer. Background technique [0002] Chemical fertilizers play an important role in ensuring and increasing food production. Due to the lack of relevant knowledge of farmers, in order to pursue crop production, the use of chemical fertilizers, urea and other fertilizers is increasing, which makes the energy consumption of my country's chemical fertilizer industry very high, resulting in fertilizer production. The waste is large, which not only increases the cost, but also pollutes the environment. [0003] In this case, there is a contradiction between fertilizers in increasing food production, saving energy, and protecting the environment. How to increase fertilizer production and save energy is an important problem that needs to be solved urgently. [0004] In view of this, there is a need in the prior art for a liquid nitrogen fertilizer that has...
