Ammonium nitrogen stabilized nitric phosphate and preparation method thereof

Abstract

Ammonium nitrogen stabilized nitric phosphate. Common nitric phosphate is mixed with an inhibitor, wherein the inhibitor is DCD or 2-chloro-6-trichloromethylpyridine (Nitrapyrin). When the DCD is employed as the inhibitor, the ammonium nitrogen stabilized nitric phosphate is prepared by mixing 100 parts by weight of the nitric phosphate and 1.3 parts by weight of the DCD; when the 2-chloro-6-trichloromethylpyridine (Nitrapyrin) is employed as the inhibitor, the ammonium nitrogen stabilized nitric phosphate, in moisture soil, is prepared by mixing 100 parts by weight of the nitric phosphate and 0.13 part by weight of the Nitrapyrin; and when the 2-chloro-6-trichloromethylpyridine (Nitrapyrin) is employed as the inhibitor, the ammonium nitrogen stabilized nitric phosphate, in black soil, is prepared by mixing 100 parts by weight of the nitric phosphate and 0.065 part by weight of the Nitrapyrin. By means of the ammonium nitrogen stabilized nitric phosphate, a use efficiency of the nitric phosphate can be increased and pollutions of the fertilizer on body of water can be reduced.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a nitrophosphate fertilizer with stabilized ammonium nitrogen and a preparation method thereof. Background technique [0002] Soil nitrogen is one of the macronutrient elements necessary for plant growth and development. It is a component of important functional substances in plants such as proteins and nucleic acids, and is the most important component of plant cell protoplasm. In addition, nitrogen is also a component of chlorophyll in plant leaves. Therefore, nitrogen plays a crucial role in determining plant yield and quality. In order to enhance the soil's fertilization capacity and meet the plant's demand for nitrogen, the application of nitrogen fertilizer has become a necessary way for agricultural producers to obtain high yield. However, since the 1990s, due to people's blind pursuit of high crop yields, long-term excessive application of nitrogen fertilizers has...

AI Technical Summary

Problems solved by technology

But a new problem is that the nitrification of ammonium nitrogen makes nitrogen fertilizer more likely to be lost in the form of nitrate nitrogen, which reduces the utilization rate of nitrogen fertilizer. Therefore, the ammonium nitrogen contained in nitrophosphate fertilizer is stabilized and long-acting transformation is imperative
