Embodiment 1

[0023] A kind of nutrient soil for landscaping nursery stock planting, comprises the following steps:

[0024] S1. Pretreatment: crush the municipal domestic sludge, pass through a 300-500 mesh sieve to remove large particles in the domestic sludge, add water to cover the domestic sludge, add slaked lime and sodium thiosulfate, and expose to oxygen The gas is kept at the first temperature and stirred for the first time to obtain deodorized sludge;

[0025] S2. Composting fermentation: dehydrate the deodorized sludge to the first water content ratio, add active microorganisms to the deodorized sludge, and put in straw and biochar, control the first temperature and ferment for the second time;

[0026] S3, decomposing: dehydrating the fermented sludge prepared in S2 to the second water content ratio, adding modified substances and mixing, and finally putting it into the decomposing bin until the temperature drops to the second temperature to obtain nutrient soil;

[0027] S4. D...

Abstract

The invention discloses nutrient soil used for planting of ornamental tree seedlings. The nutrient soil is prepared by the following steps of S1, pretreatment S2, composting fermentation, S3, decomposing; S4, detection and S5, granulation, wherein, in the step S1, municipal domestic sludge is crushed, and the crushed municipal domestic sludge passes through a 300-500 mesh screen to remove large granules in the domestic sludge; in the step S2, deodorized sludge is dewatered to a first water content ratio, active microorganisms are added into the dewatered deodorized sludge, straw and biologicalcarbon are put into the dewatered deodorized sludge, and temperature is controlled to be first temperature and fermentation is performed for second time; in the step S3, fermented sludge prepared inthe step S2 is dewatered to a second water content ratio; in the step S4, the content of phosphorus, acid and potassium and the content of organic matter in nutrient soil are detected, and the nutrient soil is adjusted by adding lots of elements including the phosphorus, the acid, the potassium and the like; and in the step S5, the adjusted nutrient soil is put into a granulator and is made into granules. The nutrient content of the prepared nutrient soil is 2-3 times more than that of common soil; the nutrient soil is green and environment-friendly; and when the nutrient soil is used for agriculture and forestry production, production efficiency can be greatly increased, and the economic income is increased.

Description

technical field [0001] The invention relates to the technical field of planting seedlings, in particular to a nutrient soil for planting seedlings in landscaping. Background technique [0002] With the rapid development of urban landscaping, the requirements for planting are becoming more and more stringent, and the demand for nutrient soil for planting seedlings is also increasing. Gardeners often have to go to the mountains to dig nutrient soil with high humus content, but this Such resources are limited and the damage to 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 sources of pollution...
