Sulfur-humic acid-containing fertilizer with alkaline soil conditioning effect and production method

Abstract

The invention relates to sulfur-humic acid-containing fertilizer with an alkaline soil conditioning effect. The sulfur-humic acid-containing fertilizer with the alkaline soil conditioning effect is directly prepared through the steps of spraying a binding agent solution on the surface of granulated fertilizer in a film coating machine by adopting a wrapping method, adding sulfur powder and humic acid powder which are uniformly mixed, and uniformly coating a film, wherein the adding amount of the sulfur and the humic acid accounts for 0.1 to 50 percent of the weight of potassium fertilizer respectively. According to the sulfur-humic acid-containing fertilizer provided by the invention, a process of spraying and coating the film on the surface of granules is adopted and the process adopts acoating and wrapping technology, so that potential dangers of the sulfur in a sulfur-containing granulated fertilizer production process are reduced; the sulfur and the humic acid in the granules of the sulfur and humic acid containing fertilizer are uniformly distributed on the surface of the fertilizer granules; the sulfur-humic acid-containing fertilizer is easily absorbed by plants in the soil, and also can have a conditioning effect on alkaline soil, so that the sulfur-humic acid-containing fertilizer is the humic acid-containing fertilizer combining an alkaline soil conditioning agent and value-adding and synergistic effects.

Description

technical field [0001] The invention relates to an alkaline soil conditioner coating fertilizer and a production method thereof, in particular to a sulfur- and humic acid-containing fertilizer capable of conditioning soil and a production method thereof. Background technique [0002] Due to people's pursuit of high economic benefits, driven by planting experience and market, and excessive application of chemical fertilizers, the phenomenon of monoculture cultivation is common, and the problem of soil degradation is becoming more and more prominent. Soil salinization, acidification, and element imbalance seriously affect the The sustainable development of my country's agriculture. [0003] Sulfur is one of the essential nutrient elements for crops and constitutes the basic nutrient elements of sulfur-containing amino acids and proteins. It can also synthesize other important biologically active substances and participate in physiological activities such as enzyme activation. ...
