Organic fertilizer and preparation method thereof

Abstract

The invention discloses an organic fertilizer and a preparation method thereof, and relates to the field of fertilizers. The organic fertilizer is prepared from the following raw materials in parts byweight: 60-70 parts of dry sheep manure, 20-30 parts of humic acid, 10-20 parts of tobacco, 5-12 parts of peat soil, 10-15 parts of straw ash, 5-10 parts of egg shells, 4-9 parts of animal bone mealand 3-7 parts of Chinese prickly ash, wherein the tobacco is one or a mixture of more of tobacco leaves, tobacco powder and tobacco stems. The fertilizer is rich in mineral elements so that the soil restores vitality, and crop roots are promoted to absorb nutrients; soil gaps can be increased, and root group development is promoted; the water retention and fertilizer retention capabilities of thesoil can be improved; the soil organic fertilizer can be supplemented later, and nutrient elements needed by crop growth are slowly released; the soil permeability can be increased, and the irrigationand drainage benefits are improved; and the price is low and the organic fertilizer can be popularized and used.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to an organic fertilizer and a preparation method thereof. Background technique [0002] With the development of agriculture and the improvement of people's living standards, especially after my country's accession to WTO, improving product quality, enhancing product market competitiveness, reducing agricultural production costs, and improving product production efficiency are the key to agricultural development and farmers' income. Fertilizers Selection is an insurmountable and crucial part to achieve these goals. [0003] As green products are deeply rooted in the hearts of the people, the production of green products has become the necessity of social development and the choice of the market. Organic fertilizer is the guarantee for the production of green products and has become the code name of green products. [0004] But at present, in the process of planting crops and vegetables, a...

AI Technical Summary

Problems solved by technology

Soil acidification will lead to the release of toxic substances, or increase the toxicity of toxic substances, which will have adverse effects on organisms

Soil acidification can also dissolve some nutrients in the soil. Under the action of rainfall and irrigation, it will infiltrate downward to replenish groundwater, causing the loss of nutrients, resulting in barren soil and affecting the growth of crops.

The second is to cause soil compaction and decline in fertility

Poor permeability, ventilation, buffering, and exchangeability; excessive use of chemical fertilizers, a large amount of NH4+, K+ and cations such as Ca2+ and Mg2+ adsorbed by soil colloids will exchange, destroying the soil structure and causing soil compaction

Extensive application of chemical fertilizers, land use without cultivation, resulting in a decline in soil organic matter, chemical fertilizers cannot compensate for the lack of organic matter, further affecting the survival of soil microorganisms, not only destroying the structure of soil fertility, but also reducing fertilizer efficiency

Third, harmful substances pollute the soil

Fourth, the quality of crops has declined, and nitrite has seriously exceeded the standard, which seriously affects human health and the harmony between man and nature.

[0005] In addition, during the growth of crops, they will be attacked by diseases and insect pests. In order to reduce or eliminate the impact of diseases and insect pests on crops, various pesticides are used during the planting and growth stages of crops, which will not only pollute soil, water and air , and pesticides will be absorbed by crops, resulting in pesticide residues in agricultural products, which seriously threaten human life and health
