Embodiment 1
[0033] The first step is to carry out thermal desorption repair treatment on the contaminated soil to meet the landscaping soil utilization standard;
[0034] In the second step, the compound soil improver is mixed evenly by 90 parts of landscaping waste, 10 parts of fully fermented poultry manure and 1 part of commercial microbial fertilizer to obtain the compound soil improver;
[0035] The third step is to mix the compound soil improver, planting soil and treated thermal desorption restoration soil according to 1:1:2, and mix well and evenly.
[0036] The fourth step is to reasonably allocate the area in the planting box, plant herbs and shrubs respectively, and maintain and manage them. Record the initial data, record the data according to 60 days in the early stage of plant growth, and then collect data samples every 30 days, and the observation period of herbs and shrubs is 6 months and 8 months respectively. like Figure 3 to Figure 10 As shown, the growth state of th...
Embodiment 2
[0038] The first step is to carry out thermal desorption repair treatment on the contaminated soil to meet the landscaping soil utilization standard;
[0039] The second step is to apply the soil improver. The compound soil improver is mixed evenly with 90 parts of landscaping waste, 10 parts of fully fermented poultry manure and 1 part of commercial microbial fertilizer to obtain the compound soil improver. The application ratio is 2.02kg / m 2 ;
[0040] The third step is to mix the compound soil improver, planting soil and treated thermal desorption restoration soil according to the ratio of 2:1:2, and mix thoroughly and evenly.
[0041] The fourth step is to rationally allocate areas in the planting box, maintenance, management, data collection and observation are the same as in Example 1. Peacock grass vegetation is in good condition, with a growth cycle of 6 months, plant height growth of 0.39cm / month, flowering period of 5 months, flower diameter of 2cm, overall flowering...
Embodiment 3
[0043] The first step is to carry out thermal desorption repair treatment on the contaminated soil to meet the landscaping soil utilization standard;
[0044] The third step is to mix the compound soil improver and the treated thermal desorption restoration soil according to the ratio of 2:1, and mix well and evenly.
[0045] The fourth step is to rationally allocate areas in the planting box and plant herbs and shrubs respectively. The maintenance, management, data collection and observation are the same as in Example 1. The plant height of peacock grass increases by 0.21cm / month, and the flowering rate is lower than that in Examples 1 and 2. , the plant growth state is lagging behind, the flowering period is 5 months, the flower diameter is 2cm, the overall flowering rate reaches 60%, and the inflorescence state is average; the height of ryegrass increases by 2cm / month, and the overall coverage reaches 70%. The proportion of leaves is 60%, and the leaf color is slightly ligh...
