Method for greening and purifying greenbelt under arbor in residential district by using Setaria plicata (Lamk.) T. Cooke

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 ...

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.
