Problems solved by technology

The disadvantages of the first type are obvious, without any coverage, it is easy to raise dust, water is easy to evaporate, and even hurt pedestrians, which is not conducive to urban environmental protection requirements and humanized demands of urban residents
Although the second method covers the bare planting pits, the ecological competitiveness of turf is higher than that of trees, which is a contradictory relationship with the growth of trees
In the later stage of tree growth, the pruning of the turf is very labor-intensive and time-consuming due to its sporadic distribution
Insufficient pruning affects the appearance
The third method fully considers the aesthetic requirements of urban citizens, but ignores 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

example 1

[0017] Example 1: Get twigs, grind and screen 80 kilograms of wood chips whose three-dimensional size is no more than 2.5cm, 4 kilograms of compound fertilizer, ZnSO 4 0.5 kg, FeSO 4 0.5 kg, 4 kg of phosphogypsum, 5 kg of acidic chemical modifier, 1 kg of green dye, stir well, spray 5 kg of adhesive, and mix thoroughly. Heating and molding with a pebble-shaped mold to make tree pit treasures with a minimum diameter of 3cm and a maximum diameter of 5cm, packed in a bag of 12kg. After being transported to the construction site, pave according to the specific depth of the planting pit, and 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 2

[0018] Example 2: Get 80 kilograms of cotton stalks for pulverization, 4 kilograms of compound fertilizer, ZnSO 4 0.2 kg, FeSO 4 0.1 kg, CaCO 4 2 kg, stir evenly; then add 6 kg of phosphogypsum, 2.5 kg of dyeing agent, stir thoroughly, add 7 kg of adhesive, mix and mold it into wood chips with a diameter of no more than 4 cm, and pack it in a bag of 12 kg after drying. 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

[0019] Example 3: Take 30 kg of wheat straw, 30 kg of tree branches, 18 kg of wood processing residue (sawdust), crush and mix, 4 kg of compound fertilizer, ZnSO 4 1 kg, FeSO 4 1 kg, CaCO 4 1 kg; then add 5 kg of phosphogypsum, stir evenly, then add 3 kg of dyeing agent and stir thoroughly, add 7 kg of adhesive, mix, heat and mold it into a star-shaped tree pit treasure with a diameter of 8 cm, and pack it in a bag of 12 kg. After being transported to the construction site, a 10cm tree pit treasure is first paved in the planting pit, and then an iron tree fence is added on it.

Abstract

A filler for tree pit is made up of natural biological material (twigs, straw, stalk, wood leftover, etc), and slow-releasing organic and microbial fertilizer through breaking off and hot die pressing to obtain plates, blocks or particles. Its advantages are high effect on preventing generation of gly dust, and directly under the blazing sun, providing fertilizer, and retaining water in soil, and beautifying environment.

Description

[0001] 1. Technical field: street tree planting pit filler and its manufacturing method 2. Background technology: [0002] With the rapid development of urban road construction, reconstruction and expansion, the scale and quality of street tree planting are getting higher and higher, which has become an important part of urban ecological environment construction. Regrettably, on the one hand, there is a large-scale increase in urban green space; on the other hand, after the planting of street trees is completed, a large number of planting pits are left, and the dust generated by them continues to become a source of urban pollution. [0003] Under the current technical conditions, after the urban street trees are planted, it is generally necessary to leave a planting pit with a certain area lower than the planting surface at the base of the trunk. Improve the survival rate and vitality of trees. [0004] For the post-treatment of street tree planting pits, the current methods ...
