Succulent plant growth matrix and preparation method thereof

Abstract

The invention discloses succulent plant growth matrix and a preparation method thereof. The growth matrix is prepared from radix isatidis residues, activated sludge, a fermenting agent and particularmatter and is loose in structure, good in breathability, high in water retention capability and capable of prevent roots of succulent plants from getting rotten because of infection of infectious microbe. The problems of high content of lignin of a large accumulation of the radix isatidis residues and the difficulty in fermentation are solved with addition of the activated sludge, the C / N ratio isadjusted, the prepared matrix has balanced nutrition, has the nitrogen content larger than 2.8% and the content of total phosphorus larger than 1.4% and the content of organic matter larger than 49%.Two solid wastes of the activated sludge and the radix isatidis residues are recycled, the environmental protection pressure of cities is relieved, and the cost is saved; the preparation process is simple and easy to operate, and the prepared succulent plant growth matrix can be widely applied to the planting field of succulent plants.

Description

Technical field [0001] The invention belongs to the technical field of waste reuse, and specifically relates to the preparation of succulent plant growth substrates by using Radix Isatidis composite activated sludge. Background technique [0002] The growth of succulents requires high soil permeability, water retention and fertilizer substrate, otherwise the roots will easily lead to root rot. The root causes of succulents are divided into physiological rot and pathological rot. The so-called physiological rot is mostly caused by poor air permeability of the cultivation substrate and poor ventilation, resulting in root rot, or caused by the use of excessive fertilizer or inappropriate organic matter. Burning roots"; the so-called pathological decay is caused by infection by pathogenic bacteria. The soil and surrounding environment, water and fertilizer, as well as the tools used for reproduction, all have pathogenic bacteria and fungi. If you don't pay attention to disinfection ...

AI Technical Summary

Problems solved by technology

[0004] Industrial solid waste, such as traditional Chinese medicine slag from traditional Chinese medicine factories and activated sludge generated from domestic sewage treatment, is generally disposed of by long-term land-occupied stacking for natural decomposition or degradation, open-air stacking of residues, or digging pits for landfill and incineration. It not only causes secondary pollution to the environment, but also takes up a lot of land resources, and also causes a lot of waste of resources

For example, domestic traditional Chinese medicine factories produce more than 30 million tons of dregs each year, which contains a large amount of isatidis dregs. Isatidis dregs contain a large amount of amino acids and some trace elements, which are very beneficial to the growth of succulents. The natural decomposition time is long, and the Radix Radix dregs are difficult to ferment and cannot be used in a large number of industrial applications; similarly, industrial solid waste such as domestic sewage treatment contains rich nitrogen, phosphorus, potassium, and organic matter. However, due to the fact that it is easy to harden during the process of composting activated sludge, when used as a plant substrate, the air permeability is poor, which is not conducive to the growth of succulents
