Sulfur-nitrogen fertilizer using ammonium bicarbonate as nitrogen sources

Abstract

The invention belongs to the field of a soil fertilizer, in particular to a sulfur-nitrogen fertilizer using ammonium bicarbonate as nitrogen sources. Ammonium bicarbonate, ammonium sulphate and calcium carbonate with low price are used as major raw materials for producing the fertilizer with the advantages that the nitrogen content is up to standard, at the same time, the sulfur content also reaches the requirement of the soil, the crop growth can be promoted, the crops have luxuriant foliage and are green, and the sulfur element in the fertilizer can promote various kinds of chemical reaction in plant bodies. The fertilizer can neutralize the redundant alkali in the soil and has the effect of regulating the acid base balance. The raw materials have low price, the fertilizer with the sufficient nitrogen content and with the sulfur content reaching the requirement of the soil can be used by farmers, and in addition, the plant cost of the farmers is also reduced.

Description

technical field [0001] The invention belongs to the field of soil fertilizers, in particular to a sulfur-nitrogen fertilizer using ammonium bicarbonate as a nitrogen source. Background technique [0002] The growth of various food crops, vegetables, fruit trees, tobacco and other economic crops requires the application of fertilizers, but most farmers only know nitrogen, phosphorus and potassium fertilizers when purchasing and using chemical fertilizers, and very few know about sulfur nutrients. Sulfur element can promote many chemical reactions in plants. It can neutralize excessive alkali in the soil and play a role in regulating acid-base balance. When plants lack sulfur, old and new leaves will turn yellow. According to relevant reports, about 30% of the cultivated land in my country is deficient in sulfur, covering an area of ​​600 million mu, and more than 20% of the soil is potentially deficient in sulfur, covering an area of ​​about 360 million mu. Most elemental fer...

According to relevant reports, about 30% of the cultivated land in my country is deficient in sulfur, covering an area of ​​600 million mu, and more than 20% of the soil is potentially deficient in sulfur, covering an area of ​​about 360 million mu. Elemental fertilizers mostly use potassium sulfate as raw material to increase the sulfur content. Potassium sulfate is expensive and costly, and the price of the manufactured fertilizer is relatively high, which causes a great economic burden on farmers
