Description
Technical field
The present invention relates to a kind of preparation method of composite fertilizer, particularly relate to a kind of nutritional type water conservation and to loosen the soil the preparation method of composite fertilizer.
Background technology
Because chemical fertilizer input amount increases year by year, the use of a large amount of fertilizer and pesticide, solves staple food supply problem, improves the output of grain.But the use of a large amount of chemical fertilizer brings very large environmental problem, and utilization rate of fertilizer declines, soil compaction year after year, water retention capacity declines, soil erosion, further the deterioration of aggravation soil physical chemistry environment, threaten the Sustainable development of agricultural to a great extent, threaten grain security.
At present, most of composite fertilizer enterprise produces water conservation soil-loosening function composite fertilizer by the mode of adding chemical floc, mainly containing two large classes: 1, inorganic chemistry class, mainly polymerize aluminum chloride, Tai-Ace S 150 etc., there is obvious large usage quantity in it, aluminium composition is high, there is certain toxic action to crop, have obvious enrichment effect, human health is produced and threatens, long-term application, produces secondary pollution to soil; 2, organic polymer class, mainly polyacrylamide, it loosens the soil, Water-saving effect better, but it uses industrial chemicals acrylamide polymerization to form, and residual a large amount of poisonous acrylamide monomer, to farm crop and all toxic effect of human body.In existing composite fertilizer production technique, clay or the wilkinite of adopting as binding agent more, and when consumption is few, effect is little, and consumption is large and reduce active constituent content, not easily dissolves in being manured into soil, and affects fertilizer release, little to soil use.
And solve the problem, can have again nutrient enriches, and reduces soil erosion, improve soil moisture content, increase the soil weight, chessom, significantly improve plant recovery of nutrient, the nutritional type water conservation of promotion agricultural production and income loosens the soil composite fertilizer, has no report in the prior art.
Summary of the invention
