Problems solved by technology

[0003] At present, the main measures to control desertified land include: "five belts in one" sand-fixing technology, wind-proof sand-fixing forest construction technology, aerial seeding afforestation technology, etc., but the difficulties in implementing these technologies are the lack of topsoil, poor water retention capacity and lack of nutrition in desertified land, which make plants survive. The rate is low, the effect is not obvious
For the land damaged by mines, filling and non-fil

Example Embodiment

[0020] Example 1: Using coal-based biosoil A formula, the content of each component is: weathered coal 35%, fly ash 40%, coal gangue 14%, bentonite 10%, water retention agent 0.2%, and soil stabilizer 0.8%. Using this example as a substrate for planting alfalfa, the plant biomass increased by 20% compared with the western desertified soil.

Example Embodiment

[0021] Example 2: Using coal-based biosoil A formula, the content of each component is: weathered coal 55%, fly ash 8%, coal gangue 35%, bentonite 1%, water retaining agent 0.9%, and soil stabilizer 0.1%. Using this example as a substrate for planting alfalfa, the plant biomass increased by 25% compared with the western desertified soil.

Example Embodiment

[0022] Example 3: Using coal-based biosoil B formula, the content of each component is: weathered coal 35%, fly ash 35%, peat 28%, bentonite 1%, water retaining agent 0.9%, and soil stabilizer 0.1%. Using this example as a substrate for planting alfalfa, the plant biomass can be increased by 35% compared with the western soil.

Abstract

The invention relates to coal base biological soil for replacing topsoil which comprises (by weight percentage) wind-blown coal 30-60%, coal gangue 10-40%, coal ash 10-40%, alta-mud 1-10%, turfy soil 10-30%, water-loss reducer 0.1-1%, soil stabilizer 0.1-1%.

Description

technical field [0001] The invention belongs to the technical field of land reclamation and ecological restoration and the field of ecological environment materials, and in particular relates to a substitute material for topsoil in land reclamation and ecological restoration. Background technique [0002] Man-made activities such as mining and natural disasters have destroyed a large amount of land and regional environments, and are the main causes of land desertification and agricultural land reduction. On the one hand, the exploitation of mineral resources has played a huge role in promoting the economic development of our country. On the other hand, it will inevitably cause damage to the land and the environment, turning plains into uneven subsidence land, and fertile farmland into low-yield slopes. Swamps or reedy lakes, dense grasslands degenerate or become sandy land, and at the same time, the accumulation of coal gangue and other mine solid waste not only occupies lan...
