The rotating shaft 3 is driven to rotate through the matching between the chain 5 and the transmission gear 4. The rotating shaft 3 rotates to drive the heat preservation unit 2 to rotate.

Referring to fig. 1 and 2, when the driving assembly 6 drives the heat preservation units 2 to rotate to the horizontal state, the adjacent heat preservation units 2 are butted, and a closed shed roof is formed between all the heat preservation units 2. When the thermal insulation units 2 are turned to the vertical state, a distance is left between the adjacent thermal insulation units 2 to form a ventilation passage. At night, the driving component 6 controls the heat preservation unit 2 to rotate, so that the heat preservation unit 2 is in a horizontal state, and the lawn is covered below. When the temperature is higher and the sunlight is sufficient in the daytime, the heat preservation unit 2 is controlled to rotate to the vertical state, so that the lawn can be conveniently photosynthetic.

Referring to fig. 4, the insulating unit 2 includes a frame 21 and an inflatable airbag 22 covering the frame 21, and the inflatable airbag 22 is filled with insulating gas. The rotating shaft 3 is fixedly connected with the framework 21.

The embodiment of the application also discloses a lawn maintenance method, which comprises the following steps of:

step one, grass combing and pruning:

appropriate amount of grass combing is carried out on the lawn before overwintering, and hay, rotten grass and hay in the lawn are removed by using a grass combing machine. When the grass combing machine is used, the mechanical height is required to be lifted, the grass is cleaned, and the cleaned grass is bagged and transported out of the site.

The height of the lawn mowing is determined according to the specific situation of the lawn, and 1/3 principle is adopted when the lawn is mowed, namely 1/3 of blades or height of the mowing is cut off. The long and high lawn is trimmed for multiple times, the required height cannot be seen once, and if the lawn is trimmed to the required height once, the capability of the lawn assimilation product is reduced, and the lawn is easy to degrade and even die.

When the lawn grows too vigorously, the trimming height of the lawn should be increased as much as possible, and the trimming can be performed after adjusting to the normal height at intervals of 3-5 days so as to enable mature leaves to be trimmed in a buffering manner.

Step two, punching: and (3) punching holes on the lawn through a punching device, wherein the number of the holes punched on the lawn is 20-30 per square meter, and the depth of the holes punched on the lawn is 8-10 cm.

Harmful gas in soil can be released by punching the lawn; improving the wetting characteristics of soil or hydrophobic soil; the drying of the long-term moist soil is accelerated; the permeability of the soil with compact surface or too thick turnip layer is improved; promoting the growth of roots in the holes after the soil rolls are punched; the cation exchange capacity of the soil is improved, and the nutrient retention of the soil is improved; improving the water retention capacity of the soil; the decomposition speed of the organic residue is accelerated.

Step three, sand covering and rolling: and after the hole is punched, covering a layer of sand on the surface of the lawn, wherein the thickness of the sand is 1cm-1.5cm. By sand coating, sand is filled into the inside of the punched hole and fills the hole. The surface of the lawn is covered with sand, so that propagation materials such as seeds, seed stems and the like can be covered and fixed, the soil moisture conservation capability can be improved, and seedling emergence is facilitated. When the established lawn grass grows on vain, the sand can maintain the lawn with good section structure, water permeability, air permeability and nutrient condition. The lawn leveling machine can be used for leveling lawns with uneven surfaces. The sand is covered on the lawn before the lawn enters the winter, so that the overwintering capability of the Gaoping grass can be effectively improved, and the drought resistance and cold resistance capability can be improved.

And rolling immediately after sand covering, and pressing or flattening by using a roller or a wooden rammer to ensure that the turf is tightly connected with the soil without gaps. After the lawn is compacted by the roller, water is uniformly irrigated in a proper amount immediately to fix the lawn and promote the rooting and growth of root systems. The first watering is enough to irrigate thoroughly, and the watering and rolling are carried out once every other week until the lawn is completely flat.

Step four, irrigation and fertilization: before the lawn is frozen, organic fertilizer such as animal excrement, grass peat and humic acid is applied, and sufficient water for overwintering is irrigated to ensure that the root system of the lawn overwintering, and proper ridging is carried out to cover the lawn with sand or a mixture of soil and the organic fertilizer, so that the lawn has the functions of heat preservation, water holding and fertilizer supply.

Lawn fertilization attention points: the fertilizer is applied uniformly without causing color spots on the lawn. Before fertilization, lawn grass is trimmed, and after fertilization, water is irrigated immediately, so that fertilizer can be absorbed quickly.

The overwintering water should be poured when the ground surface is just frozen, freezing at night is preferably carried out, and the frozen water is preferably poured and sealed when the freezing is carried out at noon in the daytime. The overwintering water is needed to be irrigated in a large amount so as to fully wet a soil layer and be irrigated by flood irrigation, the watering depth can reach about 30cm generally, but the occurrence of an ice cover is to be prevented. In the soil of the sand terrace bed, the irrigation quantity and the irrigation frequency need to be increased. And if the whole winter is in a warm winter state, determining whether to re-chill the water according to the surface water capacity.

Spraying plant antifreeze solution at temperature of 10 deg.C or lower to provide nutrient substances for lawn, and spraying once every 7-10 days when cold tide comes.

Fifthly, building a thermal insulation shed: the disclosed thermal-insulation shed of this application is built, when night, will keep warm unit 2 and turn to the horizontality, thereby butt joint in proper order between the thermal-insulation unit 2 forms the shed roof, makes the lawn be located one and is close the confined space, keeps warm to the lawn. In daytime, the heat preservation unit 2 is turned to be in a vertical state, so that carbon dioxide generated by the lawn at night can be rapidly discharged, and the lawn is exposed, so that photosynthesis can be performed on the lawn.

When cold tide occurs, hot air can be filled into the heat preservation shed, so that the cold resistance of the lawn is improved.

Sixthly, dismantling the heat preservation shed: when the average daily temperature is stabilized to be more than 2-5 ℃, the heat preservation shed is dismantled.

Seventhly, pouring green-turning water: when the temperature is kept at about 3 ℃, the irrigation can be carried out, the water amount is proper when the irrigation is carried out, the irrigation is carried out when the frost disappears in the daytime, namely, a layer of ice is formed when the irrigation is carried out in the daytime, the ice can be melted in the next day, the irrigation is carried out uniformly and thoroughly, and the soil layer is guaranteed to be wetted to 10-15 cm.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.

The above are preferred embodiments of the present application, and the scope of protection of the present application is not limited thereto, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
