Animal excrement fermented fertilizer and preparation method thereof

Abstract

The invention discloses an animal excrement fermented fertilizer and a preparation method thereof. The animal excrement fermented fertilizer is characterized by being prepared from the following raw materials in parts by weight: 75-85 parts of urea, 60-80 parts of potassium dihydrogen phosphate, 65-70 parts of saltpeter, 60-75 parts of potassium persulfate, 20-35 parts of cane sugar, 100-200 parts of rabbit excrement, 100-200 parts of pig excrement, 35-50 parts of plant ash, 2-3 parts of an EM bacterium agent, 15-25 parts of magnesium chloride, 20-30 parts of magnesium acetate, 50-85 parts of calcium nitrate and 10-12 parts of a soil activator. According to the invention, a soil improver comprises a jade composition, which contains a large number of micro elements good for a human body, and is beneficial for the human body; in addition, noxious heavy metal elements in the soil can be effectively absorbed and cured, and accordingly the heavy metal elements absorbed by the crop can be reduced; moreover, the nutrition facts of the rabbit excrement and the pig excrement are mutual complementary, as a result, the fermentation fertilizer combining the rabbit excrement and the pig excrement has more comprehensive, reasonable and uniform fertilizer nutrient compared with a single fermentation fertilizer, and crop absorption law can be better met.

Description

technical field [0001] The invention relates to a fermented fertilizer, in particular to a fermented animal manure fertilizer and a preparation method thereof. Background technique [0002] With the rapid development of my country's national economy and the continuous improvement of people's living standards, people's demand for meat, eggs and milk has gradually increased, which has led to the rapid development of my country's aquaculture industry. According to the latest report of the Food and Agriculture Organization of the United Nations, at the end of May 2010, the number of live pigs in my country reached 430 million. The rapid development of the breeding industry has played a great role in improving the lives of urban and rural people and increasing the income of farmers. However, the pollution of chicken and pig manure to the environment is becoming more and more serious. If effective measures are not taken to solve it, it will seriously affect the environment.

Problems solved by technology

Pig manure is fine in texture and poor in air permeability. Separate fermentation requires the addition of a large amount of straw powder, rice bran and other substances, and excessive addition of these substances will reduce the nutrient content and fertilizer efficiency of the fertilizer.

In addition, fermenting pig manure and rabbit manure separately and then mixing them in proportion requires additional fermentation sites, additional fermentation equipment, and additional production personnel, which will inevitably increase the cost of fertilizer production.
