Farmyard manure and preparation method thereof

Abstract

The invention discloses farmyard manure. The farmyard manure is prepared from the following raw materials in parts by weight: 30 to 50 parts of pig manure, sheep manure, 10 to 15 parts of oil cakes and 0.01 to 0.05 part of EM bacteria; the farmyard manure is prepared by adopting secondary fermenting, drying and granulating, aims to replenish the fertility of soil instead of chemical fertilizer, reduces soil hardening, promotes the development of crop roots, and facilitates the fertilization of crops.

Description

Technical field [0001] The invention relates to the technical field of fertilizers, in particular to a farmhouse fertilizer and a preparation method thereof. Background technique [0002] There are many kinds of farmyard manure, and the source is wide, and the quantity is large. It is convenient to obtain local materials and the cost is relatively low. Organic fertilizers contain comprehensive substances. It not only contains nitrogen, phosphorus, potassium, but also calcium, magnesium, sulfur, iron and some trace elements. Most of these nutrients are in the state of organic matter and are difficult to be directly absorbed by crops. The chemical and physical effects of the soil and the fermentation and decomposition of microorganisms cause the gradual release of nutrients, so the fertilizer effect is long and stable; although chemical fertilizers have replaced farm manure to a certain extent, the existence of chemical fertilizers often destroys the soil quality, especially in It...

AI Technical Summary

Problems solved by technology

The substances contained in organic fertilizers are relatively comprehensive. It not only contains nitrogen, phosphorus, and potassium, but also contains calcium, magnesium, sulfur, iron, and some trace elements. These nutrients are mostly in the state of organic matter, which is difficult to be directly absorbed by crops. The chemical and physical effects in the soil and the fermentation and decomposition of microorganisms make the nutrients gradually released, so the fertilizer effect is long and stable; although chemical fertilizers have replaced farmyard manure to a certain extent, the existence of chemical fertilizers often damages the soil quality of the soil, especially in the Used in greenhouses, the crops in the greenhouse need to be planted several times a year, the soil quality is more likely to be damaged, and the soil is easy to compact, and the root system of the crops is underdeveloped

[0003] In recent years, with the development of the economy and the improvement of people's living standards, the demand for poultry and livestock products has continued to increase, and the production scale has continued to expand. The degree of intensification of poultry and livestock breeding in my country has become higher and higher. The discharge of poultry and livestock manure seriously affects the health of humans and animals and the sustainable development of poultry and livestock breeding. The serious harm to the environment has become the main factor facing pollution in rural areas. Safely eliminate a large number of animals, insects, bacteria, etc. that endanger human health in residential areas, exacerbating the lack of natural ability to decompose human excrement in cities. At present, the utilization of poultry and livestock manure mainly includes feed and energy. and fertilizer, and used as fertilizer in the planting industry, many application methods are direct application or simple ditch application, but due to the high moisture content in poultry manure, it is very inconvenient to apply a large amount, so now poultry manure Administration of manure
