Embodiment 1

[0083]Example 1. Classification of garden plants

[0084]In this embodiment, garden plants are divided into three levels, and the specific process is:

[0085](1) Select representative artificial plant communities in urban gardens and green spaces, and screen out 70 species of plants with a frequency of more than 10% through a community survey;

[0086](2) Measure the root density characteristics of the above-mentioned 70 kinds of plants with a ground penetrating radar root scanner. Through the analysis of soil physical and chemical properties and principal component analysis, the initial permeability and stable permeability of the soil corresponding to the above-mentioned 70 kinds of plants and the garden plants are obtained. The relationship data rate, and sort the comprehensive infiltration promoting ability of the above 70 kinds of plants to the soil;

[0087](3) According to the above-mentioned relationship data between root density and soil infiltration capacity, as well as the root densi...

Embodiment 2

[0092]Example 2. Construction of a root system infiltration-enhancing garden plant community in a green space with a high pedaling frequency

[0093]This embodiment is implemented under the following implementation conditions and technical requirements:

[0094]1. In Shanghai Xinzhuang Meiyuan (total area is about 8000m2) To build a number of 20m×20m root penetration-enhancing garden plant communities.

[0095]2. The root infiltration-enhancing garden plant community is a multi-layered mixed plant community, which is divided into three parts: rainwater collection zone, leisure and recreation zone and root infiltration-enhancing zone in horizontal structure. The planting area is about 5m×20m and 7.5m respectively. ×20m and 7.5m×20m, the vertical structure is divided into upper, middle and lower layers.

[0096]3. The upper layer is composed of large and small trees.

[0097]Among them, the rainwater collection belt with a length of about 20m and a width of about 5m is planted at intervals in the up...

Embodiment 3

[0109]Example 3: Construction of a root system infiltration-enhancing garden plant community with a low frequency of pedaling

[0110]This embodiment is implemented under the following implementation conditions and technical requirements:

[0111]1. In Shanghai Zhabei Gongkang Greenland (with an area of ​​about 5000m2) To build a number of 20m×20m root penetration-enhancing garden plant communities.

[0112]2. The root infiltration-enhancing garden plant community is a multi-layered mixed plant community, which is divided into three parts: rainwater collection zone, root infiltration-enhancing zone and buffer transition zone in horizontal structure. The area is about 5m×20m, 7.5m× 20m and 7.5m×20m, the vertical structure is divided into upper, middle and lower layers.

[0113]3. The upper layer is a large tree layer;

[0114]Among them, the rainwater collection belt with a length of about 20m and a width of about 5m is planted at intervals in the upper planting area with small trees with strong in...

Abstract

The invention discloses a method for constructing a root system permeation enhancing landscape plant community. The method includes measuring root system data of common landscape plants and corresponding physical-chemical properties of soil, acquiring relation data between the landscape plants and soil permeation, ranking the comprehensive permeation enhancing ability of the landscape plants for the soil, and selecting landscape plant species having high permeation enhancing ability; dividing the landscape plants into a strong functional type, a intermediate functional type, and a weak functional type according to the comprehensive permeation enhancing ability of the landscape plants for the soil; and planting the landscape plants in a planting region in a complex manner, and forming a complex hybrid plant community. The complex hybrid plant community includes a landscape community suitable for high tread frequency green lands and a landscape community suitable for low tread frequencygreen lands. The constructed landscape plant community having high rainwater root system permeation enhancing ability can store permeated rainwater and reduce surface runoff, can generate ecological benefits and play an environmental function, and has an excellent landscape aesthetic function.

Description

Technical field[0001]The present invention relates to the technical field of gardening, in particular to a method for constructing a root system penetration-enhancing garden plant community.Background technique[0002]With the rapid development of urbanization, changes in urban land use and coverage methods have led to a continuous increase in the area of ​​impervious land coverage methods such as roads, squares, and buildings in the city, causing the original natural hydrological cycle to be interrupted, and then This has caused environmental problems such as acceleration of urban surface runoff, excessive load of gray infrastructure, unreplenishment of groundwater, loss of water resources, and even urban waterlogging. At the same time, it also increased the cost of urban garden green space maintenance. Urban gardens and green spaces are an important part of maintaining the urban ecological balance and creating a suitable living environment. It has ecological service functions such a...
