Compound microbial fertilizer and preparation method thereof

Abstract

The invention discloses a compound microbial fertilizer, comprising the following raw materials in parts by weight: 40-50 parts of crop straws, 50-60 parts of swine wastes, 20-24 parts of bean pulp, 12-16 parts of egg shells, 10-15 parts of vinasse, 20-25 parts of attapulgite, 18-22 parts of medical stones, 6-8 parts of schaumgyps, 10-12 parts of humus, 4-5 parts of lupulus, 5-6 parts of sophora alopecuroide, 3-4 parts of radix isatidis, 4-6 parts of sweet wormwood, 1-2 parts of EM fungicide and a proper amount of water. According to the compound microbial fertilizer disclosed by the invention, agricultural and sideline products such as the crop straws, the swine wastes, the bean pulp and the like are taken as main raw materials, so that the compound microbial fertilizer not only is available in materials, low in price and cost, and abundant in nutrient, but also can improve the soil structure; the added vinasse contains a plurality of organic compounds, vitamins B and cellulose, also contains abundant crude proteins and crude fat, can be used as an energy source fertilizer, and assisted with multifunctional natural raw materials with abundant nutrients, such as the attapulgite, the medical stones and the like, so that the compound microbial fertilizer has the advantages that the water-retaining property, the adsorbability and the like of the soil are increased. By adopting the fertilizer disclosed by the invention, resources are fully utilized, productive investment is reduced, the pollution caused by a chemical fertilizer is reduced, and the compound microbial fertilizer has certain environmental and economic benefits.

Description

technical field [0001] The invention mainly relates to the technical field of fertilizers, in particular to a microbial compound fertilizer and a preparation method thereof. Background technique [0002] my country is a large agricultural country. For a long time, chemical fertilizers have been applied to crops to achieve the purpose of adding nutrients and increasing production. As a determinant of crop production, chemical fertilizers play an important role in my country's agricultural production. However, although chemical fertilizers can greatly promote the growth and development of plants, chemical fertilizers pollute the environment, soil compaction, and soil structure are destroyed, and many beneficial microorganisms in the soil are gradually extinct, resulting in a decline in soil fertility and poor crop quality. defect. In addition, the application of organic fertilizers on the soil where chemical fertilizers have been applied, due to the lack of decomposition of b...

Problems solved by technology

However, although chemical fertilizers have a great role in promoting the growth and development of plants, chemical fertilizers pollute the environment, soil compaction, and soil structure are destroyed, making many beneficial microorganisms in the soil gradually extinct, resulting in a decline in soil fertility and poor crop quality, etc. defect

In addition, the application of organic fertilizers on the soil where chemical fertilizers have been applied, due to the lack of decomposition of beneficial microorganisms, the nutrients cannot be released for absorption and utilization by crops, so the fertilizer and absorption rate is low, and the fertilizer efficiency is poor.

Improving soil fertility has to increase the application of chemical fertilizers. If things go on like this, a vicious circle will inevitably form, and it will also lead to an increase in agricultural investment costs.
