Abstract

The invention discloses a rapidly disintegrating sulfur granule composition and a preparation method thereof. The rapidly disintegrating sulfur granule composition consists of 60-90% sulfur, 5-30% magnesium aluminum silicate, 0.5-5% Dispersant, 0.5-2% dispersing aid, 0.5-2.5% thickener, 1-20% substances containing medium and trace elements. The sulfur granule composition prepared by the invention can disintegrate rapidly when meeting water, and the disintegration fineness is small. At the same time, the addition of substances containing medium and trace elements can promote root growth, chlorophyll synthesis and improve crop quality; the sulfur particle composition of the invention can effectively improve the utilization rate of phosphorus and potassium, enhance the stress resistance of crops, and the effect of increasing yield is quite obvious.

Description

technical field [0001] The invention relates to a fast disintegrating sulfur particle composition and a preparation method thereof, belonging to the technical field of fertilizers. Background technique [0002] At present, the world's agricultural sulfur deficiency will reach 11 million tons, while Asia and the United States are the regions with the most serious soil sulfur deficiency in the world. Due to limited land resources, in order to achieve food self-sufficiency, China, the most populous country in the world, has experienced a serious deficit in soil sulfur balance while strengthening agricultural production. According to preliminary estimates, China's soil sulfur deficiency will reach 3 million tons. [0003] Use of sulfur for soil improvement as an alternative to pest prevention and control, for eco-friendly organic farming of food crops such as edible fruits, vegetables and bulbs. Sulfur is one of the most important essential nutrients in agriculture. It is used...
