Biological organic fertilizer and preparation method thereof

Abstract

The invention discloses a biological organic fertilizer prepared from the following raw materials in parts by weight: 100-120 parts of dry chicken manure, 40-45 parts of castor pomace hulls, 10-12 parts of peanut shells, 30-34 parts of cotton seed hulls, 20-24 parts of xylitol dregs, 10-12 parts of castor pomace, 30-34 parts of apple pomace, 20-23 parts of biogas residues, 20-23 parts of grass carbon, 10-12 parts of shell powder, 50-55 parts of urea, 30-34 parts of potassium sulphate, 24-28 parts of ammonium chloride, 12-14 parts of zinc sulfate, 6-8 parts of ammonium molybdate, 2-3 parts of ceric ammonium nitrate, 3-4 parts of EM (Effective Microorganisms) preparation, 4-6 parts of coating agent and a proper quantity of water. The fertilizer disclosed by the invention is reasonable in formula, balanced in nutrient, safe, pollution-free and capable of meeting the requirement for nutrients required by plant growth through the effective combination of an organic fertilizer, medium trace elements and a quick-acting inorganic fertilizer; and meanwhile, the biological organic fertilizer is also provided with the grass carbon and the shell powder which both take the effects of improving the soil and slowly releasing the fertilizer efficiency. The fertilizer disclosed by the invention can be used for increasing the utilization ratio of the fertilizer, prolonging the fertilization time and reducing the application amount of the fertilizer and can also be used for increasing the yield of crops, keeping the quality of plants safe, reducing the pollution of chemical fertilizers, protecting the ecological environment and promoting the modern agricultural production.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a bio-organic fertilizer and a preparation method thereof. Background technique [0002] From ancient times to the present, agriculture has played an important role in our country, and fertilizers play a decisive role in the growth of crops, so our country is also a big country in the use of fertilizers. At present, my country mainly uses chemical fertilizers, and the amount of chemical fertilizers used is also increasing, and the varieties used are mostly unit nitrogen fertilizers, while the use of multi-element fertilizers containing phosphorus and potassium elements is relatively small, resulting in soil hardening and the ability to retain water and fertilizer. Phenomena such as weakening not only waste fertilizers, but also increase the burden on farmers, and also have a certain impact on the environment. Our country has always advocated the rapid and sustainable developm...

Problems solved by technology

At present, my country mainly uses chemical fertilizers, and the amount of chemical fertilizers used is also increasing, and the varieties used are mostly unit nitrogen fertilizers, while the use of multi-element fertilizers containing phosphorus and potassium elements is relatively small, resulting in soil hardening and the ability to retain water and fertilizer. Phenomena such as weakening, not only waste fertilizers, but also increase the burden on farmers, and also have a certain impact on the environment

Our country has always advocated the rapid and sustainable development of agriculture, but due to various reasons, the utilization rate of fertilizers in our country has been kept at a low level
