Production method of garden planting soil

Abstract

The invention provides a production method of garden planting soil, construction mud and riverway mud can be effectively recycled, the wastes are turned into treasure, not only are the ecological problems produced by accumulation of the construction mud and riverway mud solved, but also significant economic benefits can be produced. Oxalic acid, acetic acid, citric acid, nitric acid, sulfuric acidor hydrochloric acid is added to a high alkaline solidified mud cake for acid neutralization, and the mud cake is stabilized in a neutral state and adapts to the growth of garden plants; by additionof an organic matter, ferrous sulfate heptahydrate and the like in the neutral mud cake, the nutrition required for the garden plant growth is met, and high-quality garden planting soil is prepared; the quality of the planting soil is better than that of planting soil actually adopted by 95% or more of garden projects; the social need is large, the transportation distance is short, the cost is extremely low, enterprise and social benefits are high, and the problem of water and soil loss caused by excavation of mountain slopes and the problem of agricultural cultivated land destroyed by excavation of farmland topsoil can be avoided.

Description

technical field [0001] The invention relates to the field of resource utilization of solid-liquid mixed-phase waste, in particular to a production method of garden planting soil. Background technique [0002] With the rapid development of the national economy and the continuous acceleration of urbanization, the construction mud and river mud in large and medium-sized cities across the country have increased sharply. How to deal with the mud? At present, some local governments and private companies have joined forces to solidify the mud into mud cakes for construction. However, relying solely on building backfill can not digest a large amount of mud waste, and secondly waste precious soil resources. On the other hand, the sources of soil for urban greening are in short supply: some rely on excavating mountains to obtain soil, which results in destruction of mountain vegetation and causes soil erosion; Therefore, using mud to solidify mud cake to modify and produce garden pl...
