Method for increasing seed germination rate and survival rate of setaria plicata

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 the under-arbors of residential quarters by using Setaria vulgaris. Technical field: [0002] The present invention relates to a method for planting a shade-tolerant lawn in the construction of green spaces in urban residential quarters, in particular to a method for greening and purifying houses by using the shade-tolerant grass species Setaria plicata (Lamk.) T. Cooke The method of green area under the arbor of the community. Background technique: [0003] Forest green space is a common form of green space in urban residential quarters. It plays an important role in adsorbing dust, purifying air, fixing CO2 and releasing O2, and enhancing landscape effects. However, there are not many shade-tolerant grass covers in the understory greens of residentia...

AI Technical Summary

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.
