Problems solved by technology

However, there are not many shade-tolerant grass layers in the green space under the forest in residential quarters, and there are fewer grass species used under the green space, resulting in the formation of weeds or bareness under many trees and shrubs, especially in residential areas. In the public green space of the community, herbaceous plants in the shade-tolerant environment under the forest are expensive to plant, slow to grow, and easy to breed mosquitoes and flies
The main reason is that there are different degrees of shading in these places, and it is difficult for ordinary sun-growing turfgrass species to survive, resulting in the generally poor quality of such understory green spaces.

Embodiment 1

[0023] Collect the fallen leaves of Melaleuca leucadendra Linn, add per kilogram of fallen Melaleuca leucadendra Linn into 3 kg of water, boil for 10 minutes, and filter to obtain the leaf extract of Melaleuca leucadendra Linn. Soak the seeds of Setaria rugosa with the leaf extract of Melaleuca mellifera leaves for 5min, and then add 10g / m 2 The density was sown into the soil under the arbor in the South China Botanical Garden (the shading rate was 40%), the weeds in the soil were removed before sowing, and the moisture content of the soil was controlled by watering during the seed germination period (generally 3 days after sowing). Between 25 and 30%, the seeds germinate and grow, and the statistics of the seed germination rate and survival rate show that the seed germination rate is 86%, and the survival rate is 60%. After the seeds of Setaria rugosa germinate, there is no need for cultivation and management. After 1 week, a dense grass cover layer with a height of nearly 10...

Embodiment 2

[0025] Collect the fallen leaves of Melaleuca leucadendra Linn, add per kilogram of fallen Melaleuca leucadendra Linn into 3 kg of water, boil for 10 minutes, and filter to obtain the leaf extract of Melaleuca leucadendra Linn. Soak the seeds of Setaria rugosa with the leaf extract of Melaleuca mellifera leaves for 8min, and then add 12g / m 2 The density was sown into the soil under the arbor in the South China Botanical Garden (the shading rate was 40%), the weeds in the soil were removed before sowing, and the moisture content of the soil was controlled by watering during the seed germination period (generally 3 days after sowing). Between 25% and 30%, the seeds germinate and grow, and the statistics of the seed germination rate and survival rate show that the seed germination rate is 87%, and the survival rate is 62%. After the seeds of Setaria rugosa germinate, there is no need for cultivation and management. After 1 week, a dense grass cover layer with a height of nearly 1...

Embodiment 3

[0027] Collect the fallen leaves of Melaleuca leucadendra Linn, add per kilogram of fallen Melaleuca leucadendra Linn into 3 kg of water, boil for 10 minutes, and filter to obtain the leaf extract of Melaleuca leucadendra Linn. Soak the seeds of Setaria rugosa with the leaf extract of Melaleuca mellifera leaves for 8 minutes, then mix 10g of humic acid per kilogram of seeds, and then add 10g / m 2 The density is sown into the soil under the arbor in the South China Botanical Garden (the shading rate is 40%), and the weeds in the soil are removed before sowing. During the seed germination period, it is generally 3 days after sowing) and the moisture content of the soil is controlled to 25% by watering. Between ~30%, the seeds germinate and grow, and the statistics of the seed germination rate and survival rate show that the seed germination rate is 95%, and the survival rate is 90%. After the seeds of Setaria rugosa germinate, there is no need for cultivation and management. Afte...

Abstract

A method for greening and purifying green fields under trees in residential areas by using Setaria plicata comprises: soaking Setaria plicata seeds for 5 to 8 minutes by using the leaf extract of dead leaves of Melaleuca leucadendra; sowing the Setaria plicata seeds with the density of 8-12 g / m2 in the soil under various trees in residential areas; controlling the soil moisture content at 25-30% for the seeds to germinate and grow. The method increases the seed germination rate and survival rate.

Description

Technical field: [0001] The present invention relates to a planting method of shade-tolerant lawns in the green space construction of urban residential districts, in particular to a greening and purifying residence using shade-tolerant grass species Setaria plicata (Lamk.) T. Cooke The method of green space under the trees in the community. Background technique: [0002] Undergrowth green space is a common form of green space in urban residential quarters. It absorbs dust, purifies air, and fixes CO2. 2 and release O 2 It plays an important role in enhancing the landscape effect. However, there are not many shade-tolerant grass layers in the green space under the forest in residential quarters, and there are fewer grass species used under the green space, resulting in the formation of weeds or bareness under many trees and shrubs, especially in residential areas. In the public green space of the community, the herbaceous plants in the shade-tolerant environment under the ...
