Problems solved by technology

However, with the large-scale use year by year, its negative effects on society and the ecological environment are becoming more and more obvious: on the one hand, due to the non-degradable rock wool, large-scale use will cause secondary pollution to the environment; on the other hand, grass peat is a non-renewable resource. , overexploitation risks depletion; moreover, they are relatively expensive if not of origin

Embodiment 1

[0017] 500kg of pharmaceutical waste residue, 50kg of alkali-making waste residue, and 100kg of mushroom culture waste residue are used for composting by mechanical stirring or manual mixing, so that the overall water content of the mixed material is about 60%, and the initial pH value of the composting material is adjusted to 8.5, and the carbon-nitrogen ratio It is 18:1. If the carbon content ratio is too high, it can be adjusted with ammonium bicarbonate or urea. The ratio of ammonium bicarbonate and urea is 15kg and 5kg respectively. The above-mentioned composting sequence is best to stir and mix several auxiliary materials first, mix them with the main material (pharmaceutical waste residue) immediately after mixing, and then place the fermentation tank for composting. The volume of compost depends on the size of the fermentation tank, but the height of the compost It should be 1.2-1.5m high, preferably slightly compacted; it is best to perform mechanical or manual turning...

Embodiment 2

[0019] 1000kg of pharmaceutical waste residue, 100kg of alkali-making waste residue, and 200kg of mushroom-growing waste residue. Use mechanical stirring or manual composting to make the overall water content of the mixed material about 65%. It is 19:1. If the carbon content ratio is too high, it can be adjusted with ammonium bicarbonate or urea. The ratio of ammonium bicarbonate and urea is 20kg and 7kg respectively. If you can operate according to the above requirements, it can be fully decomposed in 30 days in summer and autumn, and about 40 days in winter and early spring; every turn can shorten the decomposing time by 10 days, and the plant growth and survival rate is similar to that of using high-quality peat; Artificial planting soil or soil can be improved by about 10% and 20%.

Embodiment 3

[0021] 700kg of pharmaceutical waste residue, 80kg of alkali-making waste residue, and 150kg of mushroom culture waste residue are used for composting by mechanical stirring or manual mixing, so that the overall water content of the mixed material is about 65%, and the initial pH value of the composting material is adjusted to 8.5. It is 20:1. If the carbon content ratio is too high, it can be adjusted with ammonium bicarbonate or urea. The ratio of ammonium bicarbonate and urea is 25kg and 8kg respectively. If you can operate according to the above steps, it can be fully decomposed in 28 days in summer and autumn, and about 38 days in winter and early spring; every turn can shorten the decomposing time by 9 days, and the growth and survival rate of plants is similar to that of using high-quality peat; Artificial planting soil or soil can improve about 12% and 23%.

Abstract

The invention relates to a matrix special for greening and is made of Chinese herbal medicine pharmaceutical waste residue and preparation method thereof. The waste residue is the pharmaceutical residue from Chinese herbal medicine decoction pieces after being extracted with effective medical components. The matrix special for greening is obtained by that the pharmaceutical waste residue, alkali making waste residue and mushroom cultivating waste residue are mixed according to certain proportion and fully and evenly mixed after conditioner is added. The invention mainly aims at replacing prior non-renewable resources such as mineral wool and peat, etc. with pharmaceutical waste residues which is rich in cellulose, lignin and organic materials for making matrix special for greening. The material proportion of the invention is to make use of pharmaceutical waste residue and waste heat to produce quickly rotten, low cost and quality composting and realizes the using of organic solid waste in town, eliminates pollution to environment and waste of resources, further realizes the utility of social benefit, biological benefit and economic benefit and sustainable development.

Description

technical field [0001] The invention relates to the technical field of utilization of Chinese herbal medicine waste residue, in particular to a method for preparing a special greening substrate from Chinese herbal medicine waste residue. Background technique [0002] Guangdong is the hometown of Lingnan medicine and one of the main producing areas of Lingnan Chinese herbal medicine. According to statistics, there are more than 120 Chinese herbal medicine processing factories in Guangdong, processing nearly 500,000 tons of Chinese herbal medicine material (dry material) annually, and generating about 1.5 million tons (wet weight) of organic solid waste Chinese herbal medicine residue. Chinese herbal medicine uses woody and herbaceous roots, stems, leaves, flowers, and fruits as medicines. The medicinal ingredients are treated and purified, and the pharmaceutical waste residue is a high-quality organic material. At present, only a few places use a small part of herbal medicin...
