Polycarburizer and polycarburized urea and its polycarb series fertilizer

Abstract

The invention relates to a polycarbon agent and polycarbon urea and polycarbon series fertilizer, and provides preparation methods of the polycarbon agent, polycarbon urea and polycarbon series fertilizer and an application of the polycarbon agent, polycarbon urea and polycarbon series fertilizer agriculturally. The polycarbon agent is prepared by mixing three or five of sodium sarcosinate, 35% methyldiethanolamine liquid (MDEA), nanoscale calcium-based (CaO), ammonium, N-methyl diethanolamine (DIPA), monoethanolamine (MEA), diethanol amine (DEA), triethanolamine (TEA), diethylenetriamine (DETA), triethylene tetramine (TETA) and tetraethylenepentamine (TEPA) according to mass ratio in different proportions. The polycarbon urea is obtained by mixing the polycarbon agent with urea according to the proportion of 0.015-18%:99.985-82% (mass ratio). As well, the polycarbon series fertilizer is obtained by mixing the polycarbon agent with other fertilizers respectively. The polycarbon series fertilizer is used for field crops, economic crops and fruit and vegetable in agriculture, and the efficiency of the fertilizer can be improved by about 30-70%.

AI Technical Summary

Problems solved by technology

[0002] Now widely use urea and compound fertilizer (compound fertilizer), blended fertilizer, diammonium phosphate, monoammonium phosphate, nitrate phosphate fertilizer, nitrate phosphorus potassium fertilizer and other chemical fertilizers. Since scientific fertilization is not yet possible, more than 10 million tons of fertilizers are produced every year The loss of resources not only causes a great waste of resources but also pollutes the environment, the atmosphere and water bodies

In order to reduce the pollution of chemical fertilizers to the soil and the environment and improve their utilization efficiency, those skilled in the art have made many modifications to fertilizers such as urea, such as the development of dihydroamine urea, formaldehyde urea, polymer-coated urea, sulfur-coated Urea, slow-release compound fertilizers, etc. are all for slow-release and controlled-release of urea. So far, the results have not been great, and they cannot be widely used in agriculture.

The reason is that most of the slow and controlled room urea produced in the world do not have a relatively stable controlled release time, and the coating material of the coated urea accounts for 3 to 8% of the weight of the urea, which not only affects the normal nitrogen content of the urea, but also causes some difficulties. Chemicals of biodegradable polymer materials cause secondary pollution to the soil, and there is no unified evaluation of their effects, making it difficult to promote their use on a large scale
