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

[0024] 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. Statistics on 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 cm will...

Embodiment 2

[0026] 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. Statistics on 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 10 cm will...

Embodiment 3

[0028] 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

The invention discloses a method for greening and purifying green fields under trees in a residence community by using setaria plicata. The method comprises the steps of immersing setaria plicata seeds for 5-8 minutes by using a leaf extract liquid of cajeput leaf blades; sowing the immersed seeds in the soil of the green fields under various trees in the residence community at a density of 8-12 g / m<2>; and controlling water content within 25-30% during a seed germination period, so that the seeds germinate and grow. By using the leaf extract liquid of the cajeput leaf blades to treat the setaria plicata seeds, the seed germination rate and survival rate of setaria plicata are increased, wherein the seed germination rate is over 86%; and the survival rate is over 60%. By sowing the seeds in the soil of the green fields under various trees in the residence community and controlling the water content within 25-30% during the seed germination period, so that the seeds germinate and grow. After the seeds are germinated, a dense molding grass layer with a height of 10 cm can be formed in generally about a week, without cultivation and management. The grass layer is in no need of trimming. The height of the grass layer can reach 20-30 cm after two weeks. According to observations in a year, the grass layer grows well in a sample area, forms a beautiful view and has no mosquitoes.

Description

[0001] The patent application of the present invention is a divisional application with the filing date: September 10, 2012, the application number: 201210333138.4, and the title of the invention: a method for greening and purifying green spaces under trees in residential quarters using Setaria rugosa. Technical field: [0002] 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: [0003] Undergrowth green space is a common form of green space in urban residential quarters. It plays an important role in absorbing dust, purifying air, fixing CO2 and releasing O2, and enhancing landscape effects. However, there are not many shade-tolerant grass layers in the green space under the forest in resi...
