Green mixed fertilizer and preparation method thereof

Abstract

The invention discloses a green mixed fertilizer. The green mixed fertilizer is prepared from the following raw materials in parts by weight: 80-90 parts of rape seed cake, 50-55 parts of biogas residue, 10-12 parts of tobacco waste, 20-23 parts of zeolite powder, 40-45 parts of ammonium chloride, 24-27 parts of potassium phosphate, 35-38 parts of urea, 12-14 parts of potassium sulphate, 2-3 parts of magnesium sulfate, 2-3 parts of polyethylene glycol, 1-2 parts of polyvinyl alcohol, 1-2 parts of tween 80, 3-4 parts of EM bacterial agent, 4-6 parts of film coating agent and a proper amount of water. The fertilizer, which is prepared by means of mixing organic raw materials like rape seed cake, biogas residue and tobacco waste with inorganic raw materials and then fermenting, not only has inorganic nutrients like nitrogen, phosphorus and potassium, but also has a plenty of microelements and organic substances, contains beneficial microorganism, can improve soil structure, has functions of absorbing water, retaining water and fertilizer, breathing freely and improving the ecological environment of local soil, can improve the utilization rate of the fertilizer, increase plant yield, improve plant quality, realize the high quality and yield of plants, and has remarkable social, environmental and economical benefits.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a green mixed fertilizer and a preparation method thereof. Background technique [0002] Nowadays, with the continuous growth of the population and the continuous improvement of people's living standards, people's requirements for the quality of crops are also getting higher and higher. Among them, fertilizer is the key factor determining the quality of crops. my country is a big country in the production and use of fertilizers. Its output Both fertilizer and consumption rank first in the world, but product quality needs to be further improved. The main problems are low fertilizer utilization rate, short fertilizer effect period and single function, and easy to cause environmental pollution. At present, the fertilizers produced in my country mainly include inorganic fertilizers and organic fertilizers. fertilizers and biofertilizers. Perennial application of inorganic fertiliz...

[0002] Nowadays, with the continuous growth of the population and the continuous improvement of people's living standards, people's requirements for the quality of crops are also getting higher and higher. Among them, fertilizer is the key factor determining the quality of crops. my country is a big country in the production and use of fertilizers. Its output Both fertilizer and consumption rank first in the world, but product quality needs to be further improved. The main problems are low fertilizer utilization rate, short fertilizer effect period and single function, and easy to cause environmental pollution. At present, the fertilizers produced in my country mainly include inorganic fertilizers and organic fertilizers. Fertilizers and Biofertilizers

Perennial application of inorganic fertilizers will cause soil compaction and poor ventilation and water permeability, which will make it difficult for crops to produce high yields. It is also difficult to meet the requirements of farmers for output by applying organic fertilizers or biological fertilizers alone. It will pollute the environment and have a pungent smell. Now the concept of green environmental protection
