Problems solved by technology

The application of vegetation strips is different from traditional sowing, which improves the salt and drought resistance of turfgrasses. However, there are few studies on the effects of vegetation strips and graphene oxide on the growth of tall fescue under drought stress.

Embodiment 1

[0054] A graphene oxide waste vegetative belt increases the chlorophyll content of tall fescue under drought stress:

[0055] (1) Plant cultivation:

[0056] Plastic flowerpots with a diameter of 11 cm and a height of 8 cm were used to fill 250 g of campus soil, and covered with 50 g of campus soil after planting seeds; the drought gradient was divided into moderate and severe, and the moderate stress was maintained at 50%%( w / w), weighing and watering every day;

[0057] Described moderate stress refers to that the weight ratio of soil moisture content is 50% (w / w).

[0058] (2) Tall fescue planting: the amount of tall fescue seeds per pot is 1 g, the indoor temperature during plant cultivation is 18°C, the relative humidity is 30%, the light is 12000 Lx of natural light penetrating into the room, and the pots are changed every day, and the shifting ensures that the light is consistent ;

[0059] (3) Preparation and production of waste vegetation belt: select waste from th...

Embodiment 2

[0063] A graphene oxide waste vegetative belt increases the chlorophyll content of tall fescue under drought stress:

[0064] (1) Plant cultivation:

[0065] A plastic flowerpot with a diameter of 11 cm and a height of 8 cm was used, filled with 250 g of campus soil, and covered with 50 g of campus soil after planting seeds; the drought gradient was divided into moderate and severe, and the severe stress was maintained at 400% (w / w), weigh and water every day;

[0066] Severe stress refers to soil moisture content in the weight ratio of 40% (w / w).

[0067](2) Tall fescue planting: the amount of tall fescue seeds per pot is 1 g, the indoor temperature during plant cultivation is 25°C, the relative humidity is 48%, the light is 19000 Lx of natural light penetrating into the room, and the pots are changed every day, and the shifting ensures that the light is consistent ;

[0068] (3) Preparation and production of waste vegetation belt: select waste from the same source as the...

Abstract

The invention discloses a method for improving a content of chlorophyll in festuca arundinacea under drought stress by a graphene oxide waste sodded strip. The method comprises the following steps: waste is mainly selected as a carrier material of the sodded strip, the waste is exposed for one week under the sun, and the waste is used after being treated; waste newspaper is used as the lower layerof a sodded strip planting carrier, and 1 g of seeds of the festuca arundinacea are uniformly sown; waste gauze is used as the upper layer, graphene oxide is uniformly sprinkled, wherein a using amount of the graphene oxide is 0.2-0.4 mg / g, and in each sodded strip, paste and an upper carrier material are bonded and fixed to form a festuca arundinacea waste sodded strip; and after 60 days of cultivation, a plant height and biomass are measured. The method disclosed by the invention discusses influence of the graphene oxide waste sodded strip on the content of the chlorophyll in the festuca arundinacea under the drought stress, and provides technical support for planting of high-quality lawns under the drought stress.

Description

technical field [0001] The invention belongs to the technical field of urban landscaping, and relates to a method for increasing the chlorophyll content of tall fescue under drought stress in a graphene oxide waste vegetation strip. Background technique [0002] The continuous advancement of the urbanization process has enabled the rapid development of urban landscaping, which occupies an important position. As an indispensable lawn in urban landscaping, it not only has significant ecological benefits such as water and soil conservation, but also beautifies the environment, has high aesthetic value, and provides people with a place for leisure and entertainment. Due to the ecological benefits, aesthetic value and entertainment function of lawns, more and more people pay attention to them. There are many difficulties in the process of planting and management of turfgrass, such as high cost of planting and maintenance, high construction requirements, increasing soil salinizat...
