Example Embodiment

[0032] The preparation method of the soil conditioner is specifically:

[0033] In the first step, organic modification of attapulgite, 400g attapulgite was suspended in 4L at a concentration of 0.01g / ml -1 In anhydrous ethanol solution of hexadecyl trimethyl ammonium bromide, stirred at a constant temperature of 70 ℃ for 8 hours, and then filtered with suction, followed by washing the free quaternary ammonium salt with a large amount of ethanol, the solid separation was at 40 ℃ under vacuum conditions Dry and grind to obtain organic attapulgite;

[0034] In the second step, 700g of acrylamide was added to the reaction vessel, 2L of water was added to dissolve, and after the dissolution was completed, 70g of the organic attapulgite prepared in the first step and 25g of N,N'-methylenebisacrylamide were added. Add 30g ammonium persulfate to 40℃ to react for 3h, then add 2L NaOH solution with molar concentration of 1mol / L, heat to 95℃ and react for 1h. After the reaction, the product ...

Example Embodiment

[0068] Example 1 Preparation of organic compost

[0069] Fully mix 60kg of urban domestic sludge, 40g of waste plants and 50g of livestock and poultry manure, adjust the moisture content of the mixture to 45%-50%, control the C / N ratio at 20:1-30:1, and put the mixture into a closed space The first fermentation is carried out in the inside, the fermentation time is 14h-20h, and then the phased ventilation is started, the ventilation time per hour is 15-20min, and the air flow is 0.1m 3 / Min·m 3 , Last for 10d-15d, then put the obtained product outdoors, turn the pile once a day, and pile it for 18-20d to obtain organic compost.

Example Embodiment

[0070] Example 2 Preparation of Chinese herbal medicine nutrient

[0071] Astragalus 55g, Atractylodes 40g, Spatholobus spatholobus 25g, Dendrobium 30g, Cnidium monnieri 40g, Acanthopanax 30g, Saponaria spp 20g, Tangerine peel 20g, Honeysuckle 25g, Coptis 35g, Stemona 15g, Baijiu 20g, Mulberry 15g, Mix 25g of turmeric and 15g of Siegesbeckia serrata, add 1.3kg of ethanol with 95% alcohol concentration, heat and reflux for 3 hours, filter, and add 3 times the mass of the filter residue to ethanol with 95% alcohol concentration and heat reflux for extraction After 3 hours, filter, combine the filtrate, concentrate to remove ethanol, and dry to obtain Chinese herbal medicine nutrient.

Abstract

The invention provides special vegetation concrete for slope protection and greening. The special vegetation concrete comprises the following raw materials: cement, soil, plant fiber, a polyacrylamide soil improver, thin steel bars, an organic compost, plant seeds, a Chinese herbal medicine nutritional agent, an alkaline neutralizing agent and water. The thin steel bars are added in the vegetation concrete provided by the invention, so that the strength after setting is increased; furthermore, the using amount of the cement is reduced, the alkalinity of the concrete is reduced, and the vegetation concrete is more suitable for the growth of plants; by adding the polyacrylamide soil improver, the germination and emergence rate of crops can be improved, the growth and the development of the crops are promoted, and water-retaining and fertilizer-saving performances are simultaneously and obviously improved; and by adding the Chinese herbal medicine nutritional agent for providing nutritional ingredients for the growth of the seeds, the growth is promoted, pores of the concrete are increased, the alkalinity is reduced, and the final survival rate of the plants can achieve above 95%.

Description

technical field [0001] The invention relates to the technical field of ecological restoration engineering, in particular to a novel vegetation concrete. Background technique [0002] The research on vegetation concrete originated in the early 1990s. Japan first began to study greening concrete, won a patent, and established a greening design research committee on concrete structures. The United States and European developed countries have also carried out research and development of vegetation concrete since the end of the 20th century. [0003] The development and application of vegetation concrete in our country is getting more and more attention. The slope protection vegetation concrete developed by Beijing Urban Construction Engineering Research Institute is composed of cement, gravel, sand, ceramsite and water. Jilin Provincial Water Conservancy Company used construction waste bricks and stones as aggregates to develop an environmentally friendly stick-on-stick protect...
