preparation example Construction

[0029] A preparation method of special fertilizer for nano carbon eucalyptus, comprising the following steps:

[0030] Step 1. Weigh and mix urea, diammonium, calcium magnesium phosphorus, white phosphorus, potassium chloride, borax, zinc sulfate, peat soil, medical stone, and nano-carbon according to the proportion, and send them into a conical mixer for stirring for 1-2 hours;

[0031] Step 2. Send the functional bacteria liquid into the conical mixer, fully stir with other raw materials, and mix evenly;

[0032] Step 3. Send the mixed raw materials to the disc granulator for granulation, and after polishing with film hanging, use the primary vibrating screen to screen out qualified fertilizers with a particle size of 0.1-1.5mm, and send unqualified fertilizers to the secondary granulator. Granulator for secondary granulation;

[0033] Step 4. Send the qualified fertilizer into the dryer with the hoist for drying for 20-40 minutes, and then send it to the cooler to cool dow...

Abstract

The invention relates to the field of fertilizers, in particular to a nanocarbon-containing fertilizer special for eucalyptus. The fertilizer comprises the following raw materials in part by weight: 20-40% of urea, 5-16% of diamine, 5-16% of calcium magnesium phosphate, 5-16% of white phosphorus, 18-45% of potassium chloride, 1-10% of borax, 1-10% of zinc sulfate, 3-16% of peat soil, 20-40% of medical stone, 1-10% of functional bacterial liquid and 1-10% of nanocarbon. The invention further provides a preparation method of the nanocarbon-containing fertilizer special for eucalyptus. The fertilizer can not only improve the quality of eucalyptus, but also improve the soil, preventing cadmium pollution and reduce the production cost of the fertilizer special for eucalyptus.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a special fertilizer for nano-carbon eucalyptus and a preparation method. Background technique [0002] The protection of the ecological environment has a special sense of urgency in China. Since the reform and opening up, my country's agriculture has made great progress, with 7% of the land feeding 22.5% of the population, creating a miracle in the world. However, the long-term application of chemical fertilizers has led to serious negative problems such as soil structure damage, water pollution, decreased fertilizer utilization efficiency, and reduced quality of agricultural products. Green is a passport to the world. At present, my country's food safety situation is still severe, mainly in the four aspects of production, processing, distribution, and sanitation, and the source pollution of agricultural products ranks first. "Soil is the mother of crops", not only the supplier of n...
