Biogas slurry humic acid type liquid organic fertilizer and preparation technology thereof

Abstract

The invention discloses a biogas slurry humic acid type liquid organic fertilizer and a preparation technology thereof. The biogas slurry humic acid type liquid organic fertilizer comprises the following raw materials by weight: 600-700kg of biogas slurry, 140-160kg of potassium fulvic acid, 95-105kg of potassium nitrate, 18-22kg of magnesium sulfate, 1.5-2.5kg of a regulator, 1.5-2.5kg of zinc sulfate and 95-105kg of sodium humate. The preparation technology of the biogas slurry humic acid type liquid organic fertilizer comprises four steps of bacterium culture and deodorization, precipitation and filtration, deep processing and filling. The technology is simple in equipment, low in cost, easy to operate and intelligent, and human resources are saved. According to the biogas slurry humicacid type liquid organic fertilizer disclosed by the invention, a liquid organic fertilizer is used for replacing a traditional chemical fertilizer to be applied, so that the growth and the development of crops are promoted, the yield and the quality of the crops are increased, the immunity of the crops for plant diseases and insect pests can be enhanced, besides, environmental pollution can be greatly reduced, and the biogas slurry humic acid type liquid organic fertilizer has good popularization and application prospects.

Description

technical field [0001] The invention belongs to the technical field of liquid organic fertilizers, and in particular relates to biogas slurry humic acid liquid organic fertilizers and a preparation process thereof. Background technique [0002] With the rapid development of my country's economy, chemical fertilizers have become an indispensable means of production for agricultural production. Today, chemical fertilizers are the most widely used fertilizers, which are divided into nitrogen fertilizers, phosphorus fertilizers, and potash fertilizers. As the pressure of China's agricultural intensification continues to increase, the input volume and application intensity of chemical fertilizers continue to increase, which directly leads to the continuous aggravation of non-point source pollution caused by chemical fertilizer input, and environmental problems have become increasingly prominent. In agricultural production, our country is facing several major problems. First, the...

Problems solved by technology

In agricultural production, our country is facing several major problems. First, the yield does not increase after increasing the application of fertilizers; second, excessive application of chemical fertilizers;

For more than 20 years, due to excessive input of farmland chemical fertilizers and backward fertilization technology, the utilization rate of chemical fertilizers in my country is generally low, and a large amount of nutrients flow into water bodies through rainfall erosion and leaching, forming a relatively serious problem of non-point source pollution, which seriously damages the The ecological environment is damaged, and it has a relatively large negative impact on the rural environment, agricultural production and income, and farmers' lives. Water eutrophication has a great relationship with agricultural non-point source pollution.
