Abstract

The invention relates to the field of crop fertilizers, in particular to a fertilizer special for millet and an application method thereof. The fertilizer is special for the millet and is prepared from urea, superphosphate and potassium sulphate. Compared with an existing fertilizer, the composition is simpler, the fertilizer is matched with the special fertilizer application method, the fertilizer quantity is reduced, and under the condition that the fertilizer invested cost is reduced, it is ensured that the millet is high in yield, economic benefits are increased, and environment friendliness is achieved.

Description

technical field [0001] The invention relates to the field of crop fertilizers, in particular to a special fertilizer for millet and an application method thereof. Background technique [0002] As the first of the five grains, millet is known as the nurturing crop of the Chinese nation. It is a characteristic miscellaneous grain crop in my country.
