Embodiment 1
[0027] Taking the clay-heavy soil in the park of Zengcheng District, Guangzhou as the experimental soil, the experiment was carried out according to the treatment method described in the present invention.
[0028] Preparation of decomposed green plant waste products: recycle green plant waste and crush it to 2-5mm fine powder, place the fine green plant waste in a closed greenhouse with a drainage tank; then mix Enter the fermented water containing Bacillus subtilis and Trichoderma; the fermentation mixture is fermented in a closed environment with a temperature of about 60°C; during the fermentation process, the green plant waste has a water content of 40-50%, and it will be fermented for 16 days to form a decomposed product.
[0029] S1: Select a sticky and heavy soil area for planting, and dig out an area of 0.04m in the area 2 , a deep pit with a depth of 0.5m, and place about 50kg of clay-heavy soil excavated in a concentrated manner;
[0030] S2: Mix 15kg of decompo...
Embodiment 2
[0033] The soil in the park selected in Example 1 was used as the experimental soil, and the experiment was repeated, the only difference being that in step S2, the amount of decomposed green plant waste, carbide slag and polyacrylamide was 25kg, 2.5kg and 0.5kg respectively.
