Problems solved by technology

Fertilizer elements lack internal protection measures, fertilizer nutrient elements are less, fertilizer release time is concentrated, release speed is fast, release loss is large, and fertilizer efficiency is low, resulting in crops that "can't eat when they are you

Embodiment Construction

[0037] A kind of nanometer super compound fertilizer of the present invention and its manufacture method are as follows: One or several kinds of bulk ores (kaolinite, rare earth, montmorillonite, diatomite, volcanic rock, etc.) containing natural nontoxic nanomaterials are pulverized into more than 100 meshes, dissolve in 6 to 20 times the weight of water, filter out the insolubles, add 2-chloroethyltrimethylammonium chloride or potassium alum as a nanomaterial extractant, and then control the temperature between 0-80 degrees In between, add phosphoric acid (phosphate fertilizer, potassium dihydrogen phosphate, ammonium phosphate), potassium fertilizer, magnesium fertilizer, and nitrogen fertilizer in a certain proportion, stir and combine, react for 2-3 hours, and add trace element fertilizer (molybdenum, boron, zinc, iron, etc.), and finally add plant growth regulators (naphthalene acetic acid and red enzyme), granulate, and dry to obtain the finished product.

Abstract

The invention discloses a nanometer composite fertilizer and the manufacturing method in the chemical industry technique field, which produces the nanometer super composite fertilizer with the nanometer material and the sea fertilizer in place of P, K. The method comprises the following steps: purifying the nanometer material by extracting the effective material from magnesium hydrogen fertilizer, phosphate fertilizer and accelerant; neutralizing by adding N; adding the plant regulator and trace fertilizer; manufacturing different grade nanometer super composite fertilizer. The nanometer composite fertilizer has innocuous, pollution-free, the abundant material, which is fit for the root and leaf, has the good availability ratio, and has no way to estimate the social benefit.

Description

technical field [0001] The invention belongs to the field of agricultural chemical technology. Background technique [0002] At present, "Nitrogen, Phosphorus and Potassium" two-element or three-element compound fertilizers at home and abroad are products developed in the 1960s and 1970s. The technology is backward and the nutrients are monotonous. Long-term use of this formula fertilizer will make the crops "partial eclipse" And prone to insects and diseases, resulting in long-term stagnation in grain production. Furthermore, due to the large amount of phosphorus and potassium used in the fertilizer formula, the resources of phosphate rock and potassium mineral in my country are becoming more and more extensive, and the average annual market volume is less than 15%. The scarcity of raw materials has gradually increased the cost of producing compound fertilizers. On the one hand, it has reduced the manufacturer's already meager profits, and on the other hand, it has indirec...
