Abstract

The invention relates to a long-acting alkaline nitrogenous fertilizer and a production method thereof. The long-acting alkaline nitrogenous fertilizer is applied to the field of agriculture and forestry production and comprises trace elements, plant nutrition conditioners and stabilizing long-acting agents. The long-acting alkaline nitrogenous fertilizer is rich in secondary elements and trace elements which remarkably promote fast crop growth such as calcium, magnesium, sulphur, boron, manganese, zinc and the like necessary for crop growth and meets comprehensive requirements for crop nutrition. When the long-acting alkaline nitrogenous fertilizer is produced, urea, ammonium sulfate or ammonium chloride, pulverized fuel ash, magnesium calcium powder, zinc sulfate, manganese sulfate, disodium octoborate tetrahydrate and the like are prepared according to certain scientific proportions, plant nutrition conditioners and stabilizing long-acting agents of certain dosages are added then, and after full mixing and granulation, the long-acting alkaline nitrogenous fertilizer is produced. The long-acting alkaline nitrogenous fertilizer is simple in production process, easy in obtaining raw materials, overall in nutrition, and capable of providing secondary elements and trace elements while providing nitrogen for soil and plants, effectively improves utilization ratio, is suitable for acid soil due to the fact that potential of hydrogen (pH) value of the product is larger than 7, and has the advantages of improving soil and protecting the ecological environment and the like.

Description

technical field [0001] The invention relates to a long-acting alkaline nitrogen fertilizer, in particular to a long-acting alkaline nitrogen fertilizer with a pH value greater than 7, which can improve soil and protect the ecological environment and a preparation method thereof. Background technique [0002] The development of modern agriculture requires more and more nitrogen fertilizers. After nitrogen fertilizers are applied to the farmland, the part absorbed and utilized by crops only accounts for 40-60% of the total amount applied, and the rest is in the form of volatilization (NH3), leaching (NO 2 - and NO 3 - ) and denitrification are lost in vain, which not only wastes fertilizer, increases cost, but also leads to NO 2 - and NO 3 - Pollution of surface and ground water and atmospheric pollution by N2O (a product of nitrification and denitrification). The leaching and volatilization characteristics of nitrogen make the fertilizer effect period of nitrogen ferti...
