Embodiment 1

[0058] A method for regulating the protection enzyme and malondialdehyde of tall fescue under drought stress by graphene oxide waste vegetation zone:

[0059] (1) Plant cultivation: A plastic flower pot 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; moderate stress Keep it at 50%~60% (W / W), and keep it at 30% (W / W) under severe stress. Weigh and water every day, and use 1 g of tall fescue seeds per pot; The humidity is 30%, the light is 10000 Lx of natural light penetrating into the room, and the pots are turned every day, and the shift ensures that the light is consistent;

[0060] (2) Preparation and production of waste vegetation strips: select waste from the same source as the carrier material of the vegetation strips, expose to the sun for a week, cut into 9 cm circles for later use; then use 1% (W / W) hydrogen per...

Embodiment 2

[0065] A kind of method that graphene oxide waste vegetation zone regulates drought stress tall fescue protective enzyme and malondialdehyde is characterized in that it is carried out according to the following steps:

[0066] (1) Plant cultivation: A plastic flower pot 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; moderate stress Keep it at 60% (W / W), and keep it at 40% (W / W) under severe stress. Weigh and water every day, and use 1 g of tall fescue seeds per pot; during plant cultivation, the indoor temperature is 29 °C, and the relative humidity is 48 °C. %, the light is 29000 Lx of natural light penetrating into the room, and the pots are turned every day, and the shift ensures that the light is consistent;

[0067] (2) Preparation and production of waste vegetation strips: select waste from the same source as the...

Abstract

The invention discloses a method for regulating and controlling drought stress festuca arundinacea protection enzyme and malondialdehyde by using graphene oxide and waste lawn nursery strip. Accordingto the method, a plastic flowerpot is mainly adopted and filled with campus soil, seeds are laid, the moderate stress is set to be 50%-60% (w / w), and the severe stress is 30%-40%. The method comprises the following steps: selecting waste as a carrier material of the lawn nursery strip, soaking for 10 minutes by using 1% hydrogen peroxide solution, taking out and drying, using waste newspaper as the lower layer of the lawn nursery strip planting building carrier, using waste gauze as an upper layer, uniformly spreading 1g of festuca arundinacea seeds in each lawn nursery strip, then uniformlyspreading the graphene oxide, wherein the use amount of the graphene oxide is 0.2-0.4 mg / g. The purpose of the invention is to compare the differences of influences on the growth and the physiologicalecology of the festuca arundinacea by the three plant buildings ways respectively including the lawn nursery strip, the graphene oxide and the lawn nursery strip loaded with the graphene oxide, the effects of lawn nursery strip and the graphene oxide on the lawn drought stress are discussed, and a technical support is provided for planting the high-quality lawn for the drought stress.

Description

technical field [0001] The invention belongs to the technical field of urban landscaping, and relates to a method for regulating and controlling drought stress tall fescue protective enzyme and malondialdehyde with graphene oxide waste vegetation belts. 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, incr...
