Embodiment 1

[0037] Example 1 (manual control experiment in greenhouse)

[0038] 1. Cultivation of tall fescue materials

[0039] Select a special medium for horticultural plants and fine sand, mix thoroughly according to the ratio of 2:1, select a plastic flower pot with a diameter of 18 cm, put it into the substrate, pour enough water, and evenly sow the seeds, cover with a layer of previously mixed Substrate, then pour enough water. Cover with newspapers for shading treatment, and open after the seeds germinate. Water regularly every day, and compound fertilizer can be applied regularly at the same time, and the height of the seedlings should be controlled at about 8cm. The above cultivation process was carried out in an artificial climate cultivation room, the temperature was maintained at 22 / 18°C (day / night), and the humidity was maintained at 85%.

[0040] 2. Determine the optimum concentration of spermidine

[0041] To determine the concentration of spermidine, four concentratio...

Embodiment 2

[0044] Embodiment two: (under the natural environment condition of Daejeon)

[0045] 1. Tall fescue lawn establishment

[0046] Before planting, carry out deep plowing. Apply 150 kg / mu of compound fertilizer as the base fertilizer, and use a rotary tiller to plow and harrow the land. Spray 2 kg / 100m before sowing 2 , the concentration is 2% ferrous sulfate solution to disinfect the soil, and cover the surface layer with a layer of river sand with a thickness of 3cm, sow tall fescue in autumn, and the sowing rate is 20kg / mu. After sowing, rake the ground so that the seeds are covered with sand. At the beginning of sowing, water every morning and evening to keep the lawn bed moist. After the seedlings have emerged, reduce the number of watering, and cut the grass when the seedlings are 8cm high, and the stubble height is 4.5-5.5cm. After the turf is formed, water it 1-2 times a week and trim once a week according to the weather.

Abstract

The invention discloses a method for improving heat resistance of cool-season tall fescue turfgrass by externally applying spermidine, and relates to the technical field of management for landscaping turfs. The method comprises the following steps: 1, planting a tall fescue turf; 2, determining the optimal concentration of spermidine, wherein a 0.5mmol / L spermidine solution is used, so that the injury effect of high temperature to the tall fescue turf can be obviously improved, and the quality of the turf and the photosynthetic capacity are improved; 3, externally applying the spermidine solution, wherein the 0.5mmol / L spermidine solution is sprayed on leaf surfaces of the tall fescue turf when the high temperature is equal to or higher than 35 DEG C at the high-temperature initial stage of summer, the spraying amount is 85kg / mu, and spraying is supplemented for one time after one week if the high temperature lasts. According to the method disclosed by the invention, spermidine is externally applied, so that the injury of the high temperature to tall fescue is obviously reduced, and the quality of the turf is improved; the method has shorter period and faster effect than breeding for a heat resistant variety; spraying on the leaf surfaces is realized, and the operability is strong; the cost is low.

Description

technical field [0001] The invention relates to the technical field of landscaping and lawn management, in particular to a method for improving the heat resistance of cool-season lawn grass tall fescue by externally applying spermidine. Background technique [0002] Tall fescue, a perennial ground cover of the Poaceae family, can be planted in North China and Northwest, central and southern regions without extreme cold winters, East and Central China, and high-altitude cooler regions in Southwest China. It is the most widely used cool-season turfgrass in China one. Tall fescue can be used in home gardens, public green spaces, sports lawns such as parks and football fields, obstacle areas of golf courses, full sun or half shade in free areas and low maintenance areas. As a lawn grass, tall fescue can not only absorb CO 2 , release O 2 , fresh and purify the air, but also beautify the environment, reduce dust, absorb harmful gases and so on. Therefore, tall fescue plays an...
