A kind of peat vermicompost slow-release organic fertilizer and preparation method thereof

Abstract

The invention relates to a slow-release organic fertilizer containing peat, vermicompost and various plant humus. It is composed of a coating and a fertilizer body. The fertilizer body is a mixture containing peat, vermicompost and various plant humus. The coating is 5% of the total weight of the fertilizer. The main body of the fertilizer is composed of the following components in the following parts by weight ratio: peat: vermicompost: humus = 18-33: 106-142: 22-43. The invention makes full use of the characteristics of the nutrients contained in the peat, vermicompost and plant humus, and makes the slow-release organic fertilizer through configuration process, temperature control, ultrafine pulverization and mixing processing. The fertilizer can improve the quality of agricultural products and increase production and income. Controlled-release fertilizers can change the traditional method of fertilization. Most crops can only be fertilized once a season, reducing the number and frequency of fertilization, saving costs, saving time and effort and reducing waste.

AI Technical Summary

Problems solved by technology

[0003] my country is a large agricultural country. Due to the long-term and large-scale use of traditional chemical fertilizers, the demand for a single nutrient in the soil is constantly increasing, which not only increases the amount of fertilizer applied, but also increases the cost of agricultural production. It also destroys the soil structure and reduces the quality of agricultural products.

In addition, the effective utilization rate of traditional chemical fertilizer nutrients is low, and long-term use will not only cause a large loss of fertilizer nutrients

What is more serious is that the long-term large-scale application of traditional chemical fertilizers has led to increased nitrate content in groundwater, eutrophication of lake water, and increasingly serious greenhouse effects.
