Problems solved by technology

[0009] In the actual engineering application of plant-growing ecological concrete, there are many disadvantages that lead to poor final greening effect: ①Lack of nutrients during plant growth, and the root system cannot penetrate the concrete pores to take root in the soil; ②Drought weather and water shortage lead to low seed germination rate; ③ The high alkalinity of concrete will cause the roots of plants to turn yellow or necrotic, and the leaves to lose green, which will not achieve the greening effect

preparation example Construction

[0037]The preparation method of described soil conditioner is specifically:

[0038] The first step, organic modification of attapulgite, take 400g of attapulgite and suspend in 4L with a concentration of 0.01g / ml -1 In the dehydrated ethanol solution of cetyltrimethylammonium bromide, stir at a constant temperature of 70°C for 8h and then filter with suction, then wash the free quaternary ammonium salt with a large amount of ethanol, and the solid isolate is vacuumed at 40°C drying and grinding to obtain organic attapulgite;

[0039] In the second step, add 700g of acrylamide to the reaction vessel, add 2L of water to dissolve, add 70g of the organic attapulgite prepared in the first step and 25g of N,N'-methylenebisacrylamide after the dissolution is complete, Raise the temperature to 40°C and add 30g of ammonium persulfate to react for 3h, then add 2L of NaOH solution with a molar concentration of 1mol / L, raise the temperature to 95°C and react for 1h, after the reaction, ...

Embodiment 1

[0062] The preparation of embodiment 1 organic compost

[0063] 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% to 50%, and control the C / N ratio at 20:1 to 30:1, and put the mixture into a closed space The first fermentation is carried out in the room, the fermentation time is 14h~20h, and then the ventilation is started in stages, the ventilation time is 15min~20min per hour, and the air flow rate is 0.1m 3 / min·m 3 , lasted for 10d-15d, then placed the obtained product outdoors, turned the pile once a day, and piled it for 18d-20d to obtain organic compost.

Embodiment 2

[0064] The preparation of embodiment 2 Chinese herbal medicine nutrient

[0065] Mix 500g of Codonopsis, 400g of Atractylodes macrocephala, 250g of Caulis Spatholobus, 300g of Dendrobium, 400g of Cnidium, 300g of Acanthopanax, 200g of saponins, 250g of neem bark and 150g of Sanbaicao, and add 0.9kg of ethanol with an alcohol concentration of 95%. , heating to reflux for extraction for 3 hours, filtering, adding ethanol with an alcohol concentration of 95% relative to its mass to the filter residue again, heating and refluxing for 3 hours, filtering, combining the filtrates, concentrating to remove ethanol, and drying to obtain a Chinese herbal medicine nutrient.

Abstract

The invention provides a plant nutrient substrate special for promoting plant growth. The raw material components of the plant nutrient substrate include organic composts, turfy soil, wood powder, peanut shells, polyacrylamide soil conditioners, Chinese herbal medicine nutritional agents and antalkalies. Due to the fact that the polyacrylamide soil conditioners, the antalkalies and the Chinese herbal medicine nutritional agents are added, plant growth ecological concrete has the water absorption function, the water retention function, the fertilizer maintenance function, the soil structure improving function and the like, and the difficult problem that concrete is not suitable for growth of most plants due to the fact that the concrete is too high in alkalinity is solved.

Description

technical field [0001] The invention relates to the technical field of ecological restoration engineering, in particular to a novel special plant nutrient substrate for promoting plant growth. Background technique [0002] Concrete has the characteristics of abundant raw materials, low price and simple process, and is one of the most important civil engineering raw materials in contemporary times. [0003] River bank slope protection refers to the general designation of various paving and planting on the slope to prevent the river bank slope from being scoured. River bank slope protection works are divided into traditional slope protection projects and ecological slope protection projects, but both slope protection projects inevitably require concrete. [0004] However, in actual engineering construction, due to the lack of nutrients and water for plant growth in concrete, the pH value is about 13, the alkalinity is too high, and the soil moisture in the construction area i...
