Flower planting nutrient soil and production method thereof

Abstract

The invention relates to a flower planting nutrient soil and a production method thereof. The method comprises the steps of 1) mixing municipal domestic sludge, food waste residues and yeast liquid waste according to the proportion of (75-85):(15-25):(0.5-1.5), and stirring uniformly; 2), adding a certain amount of active microorganisms into raw materials in the step 1), and conducting continuous fermentation for 15-18 days; 3), placing the raw materials after fermentation into a decomposition bin until the temperature is lowered to the room temperature, and obtaining the flower planting nutrient soil; and detecting N, P and K of the decomposed nutrient soil and the content of organic matters and adjusting the nutrient soil by adding a large amount of elements such as N, P and K. According to the production method of the flower planting nutrient soil, the sources of the raw materials are rich, the production period is short, the cost is low, and the produced flower planting nutrient soil is nutritious and capable of improving the survival of plantlets, prolonging the flower season and improving the quality of the flower.

Description

technical field [0001] The invention relates to the technical field of soil, in particular to a nutrient soil for planting flowers and a production method thereof. Background technique [0002] With the rapid development of urban landscaping, the requirements for flower seedlings and planting are becoming more and more stringent, and the demand for nutrient soil for flower planting is also increasing. Gardeners often have to dig out nutrient soil with high humus content in the mountains , but this resource is limited and the destruction of mountain vegetation is serious, so it cannot be applied on a large scale. [0003] With the development of the economy, the degree of intensification of industry and agriculture is getting higher and higher. The resulting solid waste has the characteristics of various types, large quantities, and concentration. Among them, urban domestic sludge occupies a considerable share and is the main source of ecological environment. one of the sour...

Problems solved by technology

According to statistics, the annual output of wet sludge (with a moisture content of 80%) in the world exceeds 100 million tons, and the annual output of sludge in my country is about 8 million tons dry weight (converted into wet mud cake is about 32 million tons), and the annual The speed of 10-15% is increasing. Most of these sludges are simply landfilled or discarded at will, which greatly offsets the environmental purification effect of sewage treatment plants and seriously restricts the healthy development of sewage treatment. The continuous generation of organic solid waste has become a major social problem that needs to be solved urgently
