Abstract
The invention provides a preparation method of an environment-friendly composite chemical fertilizer and a composite chemical fertilizer. The preparation method comprises: (1) mixing, by weight, 180 parts of gelatin, 120-140 parts of soybean lecithin, 140-160 parts of vegetable oil, 40-60 parts of soybean meal powder and 60-70 parts of sodium dodecyl benzene sulfonate, and ultrasonically dispersing at 120-130 DEG C for 50-60 min to obtain a mixed liquid; (2) applying the prepared mixed liquid to the surface of dried chemical fertilizer master batch by pneumatic spraying, drying at 60-70 DEG C,cooling to room temperature to obtain chemical fertilizer particles; (3) mixing the coated chemical fertilizer particles with castor oil, drying, and cooling to room temperature to obtain the composite chemical fertilizer. The chemical fertilizer prepared herein is stable and reliable and has low cost and suitable contents of nitrogen and phosphorus.
Description
technical field [0001] The invention relates to the technical field of chemical industry, in particular to a preparation method of an environment-friendly compound chemical fertilizer and the compound chemical fertilizer. Background technique [0002] Chemical fertilizers are referred to as chemical fertilizers. Fertilizers made by chemical and (or) physical methods containing one or several nutrient elements needed for the growth of crops. Also known as inorganic fertilizers, including nitrogen fertilizers, phosphorus fertilizers, potassium fertilizers, micro-fertilizers, compound fertilizers, etc. They have the following common characteristics: simple ingredients, high nutrient content; quick fertilizer effect, strong fertilizer; some fertilizers have acid-base reaction; generally do not contain organic matter, and have no effect of improving soil and fertilizing. There are many types of chemical fertilizers, and their properties and application methods are quite differe...
