Problems solved by technology

The disadvantages of the first type are obvious, without any coverage, which is not conducive to the city's environmental protection requirements
The second method makes the surface temperature of the bare land higher than that of the surrounding environment during the day, which strengthens the evaporation of water on the surface, which is not conducive to the growth and development of trees
and it's not pretty
The third method only considers the aesthetic requirements of urban citizens, while ignoring the biological and ecological characteristics of trees, and the cost is too expensive
Under the current economic conditions in our country, there is no promotion value
[0005] However, the bare land in the middle of the green space is generally unable to be dealt with, leaving it exposed

example 1

[0019] Example 1: Take 80 kg of wood chips, 4 kg of compound fertilizer, 4 kg of urea, 0.5 kg of bioactive bacterial fertilizer, ZnSO 4 0.2 kg, FeSO 4 0.1 kg, CaCO 3 1 kg, stirred evenly, piled up on the ground, and rotted under aerobic conditions for 8 days; then added 4 kg of phosphogypsum, 5 kg of acidic chemical modifier, 0.4 kg of evaporation inhibitor, 0.3 kg of water-retaining agent, and 0.5 kg of dyeing agent Stir well and pack in 12 kg bags. After being transported to the construction site, pave according to the specific depth of the planting pit, the pavement thickness shall not be less than 15CM, and the workers are required to step on it with their feet so that the coverage is slightly lower than the ground.

example 2

[0020] Example 2: Take 75 kg of cotton stems, 4 kg of compound fertilizer, 4 kg of urea, 0.5 kg of bioactive bacterial fertilizer, ZnSO 4 0.2 kg, FeSO 4 0.1 kg, CaCO 3 1 kg, stirred evenly, stacked on the ground, and rotted under aerobic conditions for 8 days; then added 7 kg of phosphogypsum, 5 kg of acidic chemical modifier, 0.4 kg of evaporation inhibitor, 0.3 kg of water-retaining agent, and 2.5 kg of dyeing agent Stir well and pack in 12 kg bags. After being transported to the construction site, pave directly in the planting pit. The pavement thickness shall not be less than 15CM. After the workers are required to step on it with their feet, the coverage is slightly lower than the ground.

example 3

[0021] Example 3: Take 70 kg of wheat straw, 4 kg of compound fertilizer, 5 kg of urea, 1.5 kg of bioactive bacterial fertilizer, ZnSO 4 1.2 kg, FeSO 4 1.1 kg, CaCO 3 1 kg, stirred evenly, piled up on the ground, and rotted under aerobic conditions for 8 days; then added 8 kg of phosphogypsum, 5 kg of acidic chemical modifier, 1.4 kg of evaporation inhibitor, 1.3 kg of water-retaining agent, and 0.5 kg of dyeing agent Stir well and pack in 12 kg bags. After being transported to the construction site, pave the 10CM covering in the planting pit, and then add the covering 10CM made of wood chips on the covering. Because the capacity of treated wood chips is greater than that of wheat straw mulch, it can reduce the damage to the mulch site caused by external factors such as wind and manpower. Manually stepped on.

Abstract

A covering material for the garden or park to shield to exposed ground is prepared from natural biological material (such as tree twigs, straw, stalk, etc) through mixing with pigment, slow-releasing fertilizer and water preserving agent, and shaping to become flakes, small blocks, or particles. It can be spread on the exposed ground in garden or park for beautifying environment, providing fertilizer to trees or other plant, and preserving soil moisture.

Description

[0001] 1. Technical field: covering mixture for covering the bare soil surface of urban green space and its manufacturing method 2. Background of the invention: [0002] After the formation of urban green land, due to the ecological needs of the organism itself or the limitation of natural conditions, it is inevitable that there will be bare plots. For example, after the urban street trees are planted, a certain area of ​​bare land (planting pit) should be left at the base of the trunk. The purpose is to keep the street trees in contact with the external environment through the bare land and serve as a medium for water, fertilizer and nutrients, thereby improving the survival rate and vitality of the trees. . But the bare surface is prone to dust, affecting the appearance. [0003] In the middle of the green space, the phenomenon of bare plots sometimes appears. For example, after planting shrubs or tall trees, due to the shade effect of the canopy, the surrounding ground wi...
