Embodiment 1

[0045] (1) Preliminary preparation: Domestic waste compost comes from Tianjin Xiaodian Composting Plant. The basic physical and chemical properties are: pH 7.62, saturated water content 0.76ml / g, bulk density 0.85g / ml, total nitrogen 5.18%, available phosphorus 77.92mg / kg , organic matter 12.12%. Tall fescue (Festuca arundinacea L.) was selected as the lawn plant.

[0046] The soil of the experimental field is a loamy meadow soil with fertile soil and uniform soil fertility. The test area is 10×22m 2 , after fully preparing the ground, spread the domestic waste compost with a total weight of 50t on the experimental ground, and then press it to make the compost compact and flat, and the average thickness of the compost matrix is ​​20cm. The sowing method is spring sowing, and the seeds germinate under the condition of proper amount of watering, and the seedlings begin to emerge after one week, and the emergence is basically stable after 40 days.

Embodiment 2

[0052] The preliminary preparation is the same as in Example 1.

[0053] The above-mentioned domesticated tall fescue seeds were selected as experimental materials, and the properties of the soil required for cultivation were: pH 7.44, organic matter content 4.68%, total nitrogen 0.21%, available phosphorus 22.03mg·kg -1 , saturated water content 0.58ml.g -1 . Plastic pots were used for pot experiments. The soil substrate in each pot was 200g, the sowing amount of tall fescue was 0.8g, and the soil was repeated 3 times. The control temperature is 22°C and the relative humidity is 35%. At the beginning of sowing, each pot was fully watered to ensure the smooth germination of the seeds and the initial growth of the seedlings; two weeks later, water was given quantitatively according to the degree of water stress, reaching 60% of the field water capacity (severe drought stress), and the experimental period was 38 days. The plant height was measured, and 3 plants were determin...

Embodiment 3

[0055] The preliminary preparation is the same as in Example 1.

[0056] The above-mentioned domesticated tall fescue seeds were selected as experimental materials, and the properties of the soil required for cultivation were: pH 7.44, organic matter content 4.68%, total nitrogen 0.21%, available phosphorus 22.03mg·kg -1 , saturated water content 0.58ml.g -1 . The pot test adopts a plastic pot with a diameter of 7 cm and a height of 10 cm. The soil matrix in each pot was 200g, the sowing rate of tall fescue was 1g, and the soil was repeated 3 times. The control temperature is 26°C and the relative humidity is 30%. At the beginning of sowing, each pot was fully watered to ensure the smooth germination of the seeds and the initial growth of the seedlings; two weeks later, water was given quantitatively according to the degree of water stress, reaching 65% of the field water capacity (severe drought stress), and the experimental period was 38 days. The plant height was measur...

Abstract

The invention relates to a method for enhancing the drought resistance of festuca arundinacea by adopting domesticated plant seeds. The process of domesticating the festuca arundinacea by a domestic garbage compost substrate comprises the following steps that: the domestic garbage compost substrate is flatly spread on a sample plot, then the compost becomes compact and flat by press, and the average thickness of the compost substrate is 20cm; the sowing mode is spring sowing, water in the compost substrate, which is used for domesticating the festuca arundinacea in each year, only depends on natural precipitation, and the seeds of the festuca arundinacea are harvested after 4 domestication years; then, the seeds of the domesticated festuca arundinacea are sown in a soil substrate according to 130/m2 in spring, the temperature is controlled at 20 to 26 DEG C, the relative humidity is 30 to 50 percent, the seeds are fully watered at the initial stage of sowing, and the conditions that the seeds can successfully germinate and seedlings grow at the initial stage are ensured; water is quantitatively supplied according to the stress degree of the water content after two weeks, 55 to 65 percent of the field moisture capacity is reached, and the experimental period is 38d; and the festuca arundinacea and the substrate are mown after being cultured for 38d, the festuca arundinacea is cleanly rinsed by using distilled water, and the index of the drought resistance of the domesticated festuca arundinacea is measured.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and relates to a reasonable and safe use method for composting municipal domestic garbage. More specifically, it is a method of improving the drought resistance of tall fescue using seeds of domesticated plants. Background technique [0002] Lawn refers to the lawn lawn that is formed by artificial planting of herb plants and artificial transformation of natural grassland, which has aesthetic and ornamental effects, and can be used for people's leisure, entertainment and moderate sports. Fertilization treatment is one of the most important management methods in the lawn maintenance and management system. In order to supplement the shortage of nutrient supply in the lawn soil in time, fertilization is often used to maintain the quality of the lawn at a high level. However, urban artificial turf is not as drought-tolerant as natural grass, especially poor thirst tolerance. The ro...
