Description

A method for rapid greening using ryegrass Technical Field

[0001] The present application relates to the technical field of urban greening, and in particular to a method for rapid greening using ryegrass. Background Art

[0002] With the development of social economy, people pay more and more attention to the environment. A large number of parks and community greening constructions have made grass carpet greening a common measure. Existing grass carpets are all planted through artificial soil. For example, the patent with publication number CN105594419B discloses a grass carpet cultivation method, which includes the following steps: (1) Sunbathing: Sunbathe the soil on the ground until it is dry, and the dry soil thickness is 4-8 cm; (2) Plowing: Plow the dry soil on the surface of the ground until it is crushed; (3) Screening and concentrating the crushed soil: Then collect the crushed soil and screen it with a sieve, and throw away the larger soil blocks; (4) Build a canal: Build a canal for drainage and irrigation on the land; (5) Lay straw: Lay wheat straw evenly on the ground; (6) Watering and soaking: Pour water into the ground, then soak the soil and wheat straw for 2-3 days, then drain the water, and then use a stone roller to roll the wheat straw layer and the ground; (7) Lay straw chips: Sprinkle the wheat straw chips evenly on the rolled wheat straw layer; (8) Spread the crushed soil: Sprinkle the collected crushed soil evenly on the wheat straw chips; (9) Sow the seeds: Sow the grass seeds evenly on the crushed soil; (10) Sprinkle the crushed soil again: Sprinkle a thin layer of crushed soil on the grass seeds and completely cover the grass seeds; (11) Irrigate: Supply water to the canal until the water surface is 5mm-10mm lower than the upper end of the land, and then let the land fully absorb the water; (12) Cultivate and manage: Provide the necessary irrigation and pest control for the growth of the grass mat; (13) Water before harvest: Water the grass mat after it is fully mature. The watering operation is: water the grass mat until the crushed soil above the wheat straw layer is moist; (14) Split the grass mat: Split the grown grass mat into blocks with a machine; Using this technology to make grass mats is more difficult, and the steps are more complicated. Most of them are manual work, which requires a lot of manpower cost and takes a long time to complete. Summary of the Invention

[0132] S22: Lay 2 cm of planting sand in the planting box using a straw carpet production line and scrape it flat, then spray fungicide;

[0133] S23, laying the cultivated ryegrass blanket on the planting sand;

[0134] S24, using a straw blanket production line to cover the ryegrass blanket with 0.5 cm thick planting sand to completely enclose the straw blanket root system;

[0135] S25, sowing perennial grass seeds at a time according to a proportion and sowing amount, and reseeding;

[0136] S26, using the grass carpet production line to cover the grass seeds with a layer of planting sand;

[0137] S27. Use the straw carpet production line to water, maintain and prune the grass, and it can be used on the 9th day.

[0138] Moreover, in step S13, the temperature in the greenhouse is 22-25° C., the humidity is 40% rh, and a fill light is provided in the greenhouse. The fill light has a fill time of 2.5 h / d and a light intensity of 3500 LX.

[0139] Moreover, in step S25, the perennial grass seeds are bluegrass and tall fescue; the mass ratio of bluegrass and tall fescue is bluegrass: tall fescue = 5:5, and the sowing amount of the perennial grass seeds is 35g / m 2 .

[0140] The straw carpet production line is the same as that in Example 1.

[0141] Comparative Example 1

[0142] This comparative example is the same as Example 3 except that the ryegrass seeds are not soaked in water.

[0143] Comparative Example 2

[0144] This comparative example is the same as Example 3 except that in step S12, the grass seeds are spread evenly on the hydroponic seedling tray, the particles are sparse and there are gaps therein, and the thickness is 0.3 cm.

[0145] Experimental part

[0146] On the 4th day, the germination rates of the ryegrasses of the embodiment and the comparative example were counted, the mat formation time of the embodiment and the comparative example was counted, and the mat formation status of the ryegrasses was observed. The specific results are shown in Table 1.

[0147] Table 1 Ryegrass germination and mat formation

[0148]

[0149] As can be seen from Table 1 above, the germination rates of Examples 1-3 and Comparative Example 2 on the third day were 96%-98%, and the mat formation time was 6-7 days. After the mat was formed, the seedlings of Examples 1-3 grew dense and lush, with no exposed soil. However, the germination rate of Comparative Example 1 was only 85%, and the mat formation time increased to 9 days. After the mat was formed, the seedlings were sparse, and some leaves turned yellow. This is because Comparative Example 1 did not soak the ryegrass seeds in water, which can promote seed germination and accelerate the formation of the ryegrass mat. The present invention uses water soaking to increase the seed germination rate and also accelerate the formation of the ryegrass seed mat. The seedling trays of Comparative Example 2 were sparse with gaps and insufficient thickness, resulting in sparse seedlings, yellowing of some leaves, and exposed soil.
