Embodiment 1

[0015] Location: Under the forest on the side of the staff dormitory in Building 37, South China Botanical Garden, Chinese Academy of Sciences, with a shading rate of 30-50%.

[0016] First, the experimental plot is prepared to remove the weeds in the soil, and then the seeds of the small flower dew seed are pressed by 10g / m 2 Sow at a certain density and water for one to two days after sowing. Then cultivate and manage according to conventional methods to ensure sufficient water and nutrients. After two weeks, the lawn will take shape. After long-term observation, the lawn grows well in the sample plot, and the quality of the lawn is high. It can grow to a height of 10-50cm within a year, and generally does not need pruning. In the future, the height of pruning depends on the needs. If there are many weeds during this period, they should be removed in time. After that, they can be pruned every four months or so.

Embodiment 2

[0018] Location: Under the bamboo forest in the South China Botanical Garden of the Chinese Academy of Sciences, the shading rate is 70-80%.

[0019] First, the experimental plot is prepared to remove the weeds in the soil, and then the seeds of the small flower dew seed are pressed by 15g / m 2 Sow at a certain density and water for one to two days after sowing. Then cultivate and manage according to conventional methods to ensure sufficient water and nutrients. After two weeks, the lawn will take shape. After long-term observation, the lawn grows well in the sample plot, and the quality of the lawn is high.

Embodiment 3

[0021] Location: Under a viaduct in Guangzhou, shading rate: 80-90%.

[0022] First prepare the experimental plot to clear the weeds in the soil. Since the soil is relatively poor, apply a certain amount of organic fertilizer as the base fertilizer, and then transplant the seedlings of S. chinensis into the plot and water for one to two days. Then cultivate and manage according to conventional methods to ensure sufficient water and nutrients. After two weeks, the lawn will take shape. After long-term observation, the lawn grows well in the sample plot, and the quality of the lawn is high.

Abstract

The invention discloses a method for building a shade-resisting lawn by using ottochloa malabarica, which comprises the steps of: sowing seeds of ottochloa malabarica or planting the ottochloa malabarica in soil of a shaded zone with a shading rate of 30-90 percent in a sprout transplanting manner, then carrying out cultivation management according to a conventional method, and growing the ottochloa malabarica in the soil of the shaded zone into the lawn. The ottochloa malabarica has strongest shade tolerance, can keep normal growth under the degree that the shading rate reaches 90 percent, is easy to plant and survive as well as manage, rapid in growth and quick in covering the earth's surface, and can form a compact lawn within shorter time; and the ottochloa malabarica is planted in the soil of the shaded zone, the lawn can be formed for about two weeks after managed through conventional cultivation, has strongest shade resistance, and grows better in the shaded zone, such as around city tall building and below a greenbelt and a viaduct bridge.

Description

Technical field: [0001] The present invention relates to a kind of planting method of shade-tolerant lawn in the construction of urban green space, in particular to a kind of method of using shade-tolerant grass species Ottochloa nodosa (Kunth) Dandy var.micrantha (Balansa) Keng f. ) to establish a shade-tolerant lawn. Background technique: [0002] Lawn green space is a common form of green space in urban greening. It can absorb dust, purify air and fix CO 2 and release O 2 It plays an important role in increasing the landscape effect. At present, the construction of lawns and green spaces in cities and towns in my country is developing rapidly. However, there are not many shade-tolerant lawns, and there are fewer grass species used in green forests, resulting in the formation of weeds or bareness under many trees and shrubs, and more under the viaducts or in the shade of buildings. bare ground. The most important reason is that there are different degrees of shading i...
