Zoological planting method for producing economic forest and charcoal fertilizer based on sludge treatment

Abstract

The invention discloses a zoological planting method for producing an economic forest and charcoal fertilizer based on sludge treatment. The method comprises the following steps that the forest land is selected to plant eucalypt saplings; town sludge is transported to the eucalypt forest land, and sludge is laid along the single edge of the eucalypt; strong stems of Alfred Stonecrop and strong stems of alocasia (or pennisetum hydridum) are selected and transplanted to the town sludge laid on the eucalypt forest land; the Alfred Stonecrop and the alocasia (or the pennisetum hydridum) are respectively harvested. According to the three-dimensional ecological planting method, fertilizer nutrient and microelements in the sludge can be safely utilized, and qualified plant products can be produced; the economic forest and charcoal fertilizer are produced, and economic benefits are obtained; the advantages of carbon sequestration and air purification of planted eucalypt forest are brought into play, the characteristics of various ecologically planted plants are combined, water and soil loss is reduced, the environmental risk of non-point surface pollution due to nitrogen phosphate fertilizer loss is reduced, social benefits, economical benefits and ecological benefits are produced, and multiple environmental-friendly and economic targets are achieved.

Description

technical field [0001] The invention belongs to the field of environmental ecological protection, and in particular relates to an ecological planting method for producing economic forest and biochar fertilizer based on sludge treatment. Background technique [0002] The plantation area of ​​eucalyptus plantations in my country has reached 3.6 million hectares (ha or hm) in the past 20 years. 2 ). With the continuous expansion of the area of ​​eucalyptus plantations, all sectors of society are paying more and more attention to the negative problems that eucalyptus forests will cause serious degradation of forest land soil, reduction of regional water resources and water quality, and pollution of non-point source water, which pose a threat to environmental safety. These possible ecological problems Environmental problems have affected the development of eucalyptus plantations in some areas to a certain extent. Eucalyptus plantation grows fast, has high planting density, abso...

Problems solved by technology

[0006] The basic method of using urban sludge for plantation is generally to use sludge as a raw material to be processed by fertilizer companies into organic compound finished fertilizer, and then mixed into soil for application. This requires a certain production cost, while direct laying There is no report on the forestry application of sludge to exert its fertilizer effect

Application No. 200510126409.9 A method of using solid waste to grow plants to produce organic potassium fertilizer and Application No. 201310276718.9 A method of using imperial bamboo grass to transform urban sludge into plant products. Both of these patents introduce the use of urban sludge to produce potato And emperor bamboo grass is used as an organic potassium fertilizer, but in practical applications, large-scale planting of calla lily is often used as a potted plant for appreciation purposes, and large-scale production of emperor bamboo grass is generally used as a feed plant. Emperor Bamboo Grass) to produce fertilizer, considering the actual situation of covering a large area, it is difficult to promote in a large area
