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.

Abstract

The invention provides a processing method for heavy soil in garden engineering. The method comprises the steps that S1,a heavy soil area for planting is selected, and heavy soil is dug out in the area and placed concentratedly; S2,greening plant waste decomposed products, carbide slag and polyacrylamide are mixed with the dug heavy soil; S3,the mixed soil obtained in S2 is subjected to backfilling in a soil body. According to the processing method for the heavy soil in garden engineering, long lasting improvement on the physicochemical property of the heavy soil is achieved, and the heavy soil becomes high-quality urban gardening soil which has good functions of water storage, fertilizer conservation and air permeability and meets the plant growth and greenbelt water resource conservationfunction.

Description

【Technical field】 [0001] The invention relates to the field of soil improvement, in particular to a treatment method for sticky and heavy soil in garden engineering. 【Background technique】 [0002] In recent years, with the construction and development of cities, the landscaping construction business has made great progress. Urban green space, as the only negative feedback regulation system in the city that bears the natural "pollution and spit out new", plays an important role in improving the urban ecological environment and beautifying the urban landscape. However, urban green land soil, which is the base of urban green land, suffers from the environmental pressure brought about by the process of urbanization and the serious interference of human activities. A large amount of original topsoil in the garden park has been continuously destroyed, and the soil matrix is ​​mostly artificial backfill soil, which contains a large amount of soil intrusions, such as gravel, lime,...
