Embodiment 1

[0058] (1) Weigh 300g of vermicompost, compost or vermicompost-compost mixture (wherein the vermicompost:compost weight ratio is 1:1) and place it in a tall beaker, with the ratio of water:soil (raw material)=2:1 Add 600mL of distilled water, shake the beaker on a constant temperature oscillator for 2 hours, let it stand overnight, and filter to obtain pure vermicompost, pure compost or pure vermicompost-compost mixed extract, which is set aside.

[0059] (2) Ryegrass, tall fescue or bluegrass seeds are sun-dried for 2-3 days before soaking, then take the full and uniform seeds respectively, and sow them in the petri dish of vermicompost, compost or vermicompost-compost mixed extract , the amount of the extract is twice the weight of the seeds.

[0060] (3) Place the petri dish on the laboratory plant culture platform to germinate, the temperature is 18.5°C, the average humidity is 52.5%, the soaking time is 48 hours, the continuous soaking method is adopted, the natural light...

Embodiment 2

[0064] Source of raw materials: The domestic waste compost in Xiaodian, Tianjin was used as the test substrate. The lawn plants are perennial ryegrass (Lolium perenne L.) and tall fescue (Festuca arundinacea L.).

[0065] Earthworms were Eisenia fetida provided by Tianjin Ninghe Jia Liming Earthworm Breeding Company.

[0066] Preparation:

[0067] (1) Weigh 500g of vermicompost and place it in a container (beaker), add 600mL of distilled water at a ratio of water: vermicompost=2:1, place the beaker on a constant temperature shaker for 5 hours, place it overnight, and filter to obtain pure Vermicompost extract, for later use.

[0068] (2) Sun-dry the seeds for 3 days before soaking the seeds, then take the full and uniform seeds of ryegrass, tall fescue or bluegrass, and sow them in the petri dish of vermicompost extraction solution. The amount of extraction solution is the weight of the seeds. 2 times.

[0069] (3) Put the petri dish on the laboratory plant culture platfor...

Embodiment 3

[0073] Source of raw materials: Same as before

[0074] Preparation:

[0075] (1) Weigh 300g of compost and place it in a container (beaker), add 600mL of distilled water at a ratio of water:compost=2:1, place the beaker on a constant temperature shaker for 4 hours, place it overnight, and filter to obtain pure compost extraction liquid, spare.

[0076] (2) Sun-dry the seeds for 3 days before soaking, then take ryegrass seeds with plump and uniform grains, and sow them in a petri dish with compost extract, and the amount of extract is 3 times the weight of the seeds.

[0077] (3) Put the petri dish on the laboratory plant culture platform to germinate, the temperature is 20°C, the soaking time is 72 hours, the natural light is used to transmit, and the water is managed in equal amounts every day, so that the seeds can absorb enough water evenly and keep the substrate in the original water state .

[0078] (4) When the seed radicle grows out and exceeds half of the seed leng...

Abstract

The invention discloses the applications of earthworm cast, dunghill, and mixing leaching liquor soaking seeds of the earthworm cast and the dunghill in the aspect of improving the early-stage growing vitality of a lawn plant which improves the early-stage growing vitality of the lawn plant through 3 methods of soaking seeds by water extract; thereby reaching the target of improving excellent lawn building at the early-stage of the lawn. A test result shows that the earthworm cast, the dunghill, and the mixing leaching liquor soaking seeds of the earthworm cast and the dunghill can improve the seed bourgeon rate of the lawn plant and the leaching liquor with a certain proportion has remarkable promoting effects on increasing the biomass on a land of ryegrass and tall fescue; wherein, the effect of the earthworm cast is the most remarkable; meanwhile, the water extract also increases the chlorophyll content of the plant, promotes the photosynthesis and growth of the plant and improves the capacity of the lawn plant to compete with weeds; thereby reaching the target of improving the excellent lawn building at the early-stage of the lawn.

Description

technical field [0001] The invention belongs to the technical field of urban environmental protection, and relates to the application of various extracts for soaking seeds in lawn plants, more specifically, the application of vermicompost, compost or vermicompost-compost mixed extracts for soaking seeds in improving the initial growth vitality of lawn plants. application. Background technique [0002] With the continuous acceleration of urban construction, urban greening projects are becoming more and more important, and the corresponding lawn industry is showing great vitality. Urban lawns can purify the air and absorb toxic and harmful gases such as carbon dioxide, sulfur dioxide, hydrogen fluoride, ammonia, and chlorine in the atmosphere. Urban lawns can also adjust atmospheric temperature and humidity, have the functions of purifying air, retaining water and fighting drought, beautifying the environment, regulating climate, reducing noise, adjusting air temperature, and...
