Embodiment 1

[0029] (1) Preparation of waste planting carrier materials

[0030] Select waste from the same source as the material for cultivating the planting carrier, including waste cotton cloth; waste newspaper; waste gauze; waste facial tissue; expose each material to the sun for a week, then soak in 1% hydrogen peroxide solution for 10 minutes, take out Dried in the sun; then use discarded newspapers and discarded cotton cloth as the lower layer of the planting carrier for the planting tape, waste gauze and discarded facial tissue as the upper layer of the planting carrier as the planting tape, and sow 0.5g of ryegrass seeds on a round 8 cm in diameter The area is fixed with the upper carrier to make a ryegrass planting belt to ensure the uniformity of the seeds; the method of carrier fixation refers to: edible wheat flour is put into boiling water at 100 °C and fully stirred to make a paste, then it is made Carrier fixative, and adhesive fixation; the ratio of wheat flour to water i...

[0038] 1.1.1 Preparation of waste planting carrier materials

[0039] Select waste from the same source as the material for cultivating and planting carriers, including waste cotton cloth, which is simplified as C below; waste newspaper, which is simplified as N below; waste gauze, which is simplified as G below; waste facial tissue, which is simplified as below T to simplify the representation. Expose each material to the sun for a week, then soak in 1% hydrogen peroxide solution for 10 minutes, take it out and dry it in the sun to disinfect and ensure the normal germination of turfgrass seeds. Respectively, discarded newspaper and waste cotton cloth were used as the lower layer of the vegetation belt establishment carrier, and waste gauze and discarded facial tissues were used as the upper layer of the vegetation belt establishment carrier.

Abstract

The invention discloses a method for regulating proline and malondialdehyde of Festuca elata Keng subjected to water stress by adopting sodded strips. The method comprises the steps of: using waste newspaper and cotton cloth as the lower layer of a carrier on which sodded strips are planted, and using waste gauze and tissue paper as the upper layer of the carrier on which the sodded strips are planted; by adopting the pot-culture method, adding dried raw soil in a container, then flatly laying the sodded strips on the raw soil, guaranteeing the amount of water required by seed germination after sowing until germination; beginning to stress after 5d of germination, and controlling the soil water content at 35 percent to 50 percent of the saturated water-holding capacity; and after 40 days of germination, measuring various physiological and biochemical indicators of young seedlings of Festuca elata Keng, cutting the part of the Festuca elata Keng on the ground, continuing to culture for 40 days, and harvesting the second-crop grass and the underground part, wherein the total culture period is 80 days, the average temperature is 18-22 degrees, and the average humidity is 30-40 percent. As proven by the experimental result: when plants are subjected to water stress, the sodded strips planted on wastes have good regulating effect on the growth of lawn grass.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and relates to a method for regulating tall fescue water stress proline and malondialdehyde by harvesting vegetation belts. Background technique [0002] With the increasing shortage of water resources, how to use water resources economically and rationally in urban green spaces has become a hot research issue. Water is an important part of plants, whether it is a long-term drought or a short-term water deficit will have adverse or even harmful effects on the growth and development of plants. The area of ​​lawns and green spaces in today's cities continues to grow, and its water use issues have also attracted more and more attention. The traditional water-saving methods of lawns are realized through the selection of drought-resistant varieties, the selection of lawn economical irrigation amount and irrigation methods, etc. At present, the application of water-retaining agents a...
