Abstract

The invention relates to a sulfur-based compound fertilizer and a method for preparing the same. The sulfur-based compound fertilizer is characterized by comprising, by weight, 5-10 parts of ammonium sulfate, 5-10 parts of potassium sulfate, 5-10 parts of urea, 5-7 parts of ammonium phosphate, 8-10 parts of calcium sulfate and 70-80 parts of straw fermentation materials. The sulfur-based compound fertilizer is a granular fertilizer. The granular fertilizer is divided into structures of inner layers and outer layers, the outer layers are the straw fermentation materials, and the ammonium sulfate, the potassium sulfate, potassium-magnesium fertilizers, plant ash, the urea, the ammonium phosphate and the calcium sulfate are positioned on the inner layers. The sulfur-based compound fertilizer and the method have the advantages that nutrients in the sulfur-based compound fertilizer can be prevented from being lost along with irrigation, and accordingly downstream water can be prevented from being contaminated while planting nutrients are guaranteed.

Description

technical field [0001] The invention relates to the biological field, in particular to a sulfur-based compound fertilizer and a preparation method thereof. Background technique [0002] Vegetable production is a highly intensive planting system, and excessive application of fertilizers is a common phenomenon. Due to the high planting efficiency, vegetable farmers use super-high amounts of nitrogen and phosphorus fertilizers in order to pursue benefits. The average pure nutrient consumption of single-season crops is 569-2000kg / hm2, which is several times or even dozens of times that of ordinary field crops. Many studies have shown that long-term and large-scale application of nitrogen and phosphorus fertilizers will lead to excessive accumulation of nitrogen and phosphorus nutrients in the soil. Excessive soluble nutrients in vegetable field soil enter the environment through farmland surface runoff, drainage, and underground seepage, resulting in eutrophication of groundwat...
