For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] See also Figures 1 to 5 In an embodiment of the present invention, a film for intensive planting of flower production includes a film 1 and a heat-insulating film 2, wherein the film 1 consists of an inhibition layer 3 and a light-isolating layer 4, wherein the light-isolating layer 2 adheres to the outer surface of the inhibition layer 3, and the inhibition layer 3 includes polyethylene, phosphite, heat-insulating agent, sodium polyacrylate and herbicide, wherein 500 parts of polyethylene, 30 parts of phosphite, 20 parts of heat-insulating agent, 50 parts of sodium polyacrylate and 30 parts of herbicide are fully stirred and mixed, and then introduced into a film-making machine for conforming, extrusion, blow molding, and then pulling and winding to obtain the inhibition layer 3, wherein the film-making machine uses an existing general film-making machine, which is a prior art, so it is not repeated here, and the inhibition layer 3 made by the above-mentioned processing has good anti-aging and anti-weed functions, and the herbicide components contained therein can effectively inhibit the growth of weeds. At the same time, the light-isolating layer 4 includes polypropylene, metallocene polyvinyl chloride, high-density polyethylene powder, phosphite, calcium stearate, reflective glass beads and ultraviolet absorbers, wherein 500 parts of polypropylene, 200 parts of metallocene polyvinyl chloride, 150 parts of high-density polyethylene powder, 10 parts of phosphite, 8 parts of calcium stearate, 10 parts of reflective glass beads and 30 parts of ultraviolet absorbers are fully stirred and mixed, and then introduced into a film-making machine for conforming, extrusion, blow molding, and then traction and winding to obtain the light-isolating layer 4. The light-isolating layer 4 made by the above processing has good anti-aging and light-isolating properties. The reflective glass beads and ultraviolet absorbers added inside increase the reflective performance of the light-isolating layer 4 to sunlight, reduce the light transmittance of the coating 1, and then weaken the photosynthesis of weeds in the soil inside the film, thereby inhibiting the growth of weeds.

[0025] Among them, the thermal insulation film 2 is composed of a thermal insulation layer 5 and an antifreeze layer 6, wherein the antifreeze layer 6 adheres to the outer surface of the thermal insulation layer 5, and the thermal insulation layer 5 includes polypropylene, high-density polyethylene, thioether, drip agent and plant fiber, wherein 500 parts of polypropylene, 200 parts of high-density polyethylene, 3 parts of thioether, 5 parts of drip agent and 50 parts of plant fiber are fully stirred and mixed, and then passed into a film making machine for conforming, extrusion, blow molding, and then traction and winding to obtain the thermal insulation layer 5. The thermal insulation layer 5 made by the above processing has good thermal insulation function. Processing plant fiber therein greatly increases the thermal insulation performance of the thermal insulation layer 5, keeps seeds warm and ripens, and improves the germination rate of seeds. In addition, the hardness of the thermal insulation layer 5 is relatively low, which is convenient for flowers to break out of the thermal insulation film 2.

[0026] Among them, the antifreeze layer 6 includes an epidermis 61, an elastic layer 62 and an adhesive layer 63, wherein the epidermis 61, the elastic layer 62 and the adhesive layer 63 are bonded together end to end in sequence, wherein the epidermis 61 and the elastic layer 62 are made of polypropylene fiber, and the elastic layer 62 is made of polyurethane material, and a plurality of lower semicircular grooves 64 are opened at the bottom of the elastic layer 62, and a plurality of upper semicircular grooves 65 are opened at the top of the elastic layer 62, and the upper semicircular grooves 65 are symmetrically arranged with respect to the lower semicircular grooves 64, and the interiors of the lower semicircular grooves 64 and the upper semicircular grooves 65 are filled with antifreeze, and the antifreeze is a polyol mixed solution.

[0027] See also Figures 4-5 When the temperature in the incubation room is low, when ice first forms, an ice layer 7 will form on the outer surface of the epidermis 61. At this time, the temperature of the ice layer 7 does not reach the freezing point of the antifreeze liquid, and the shape of the epidermis 61 will not change significantly. Figure 4 As shown; when the ice is formed, the temperature of the ice layer 7 drops to the freezing point of the antifreeze, the antifreeze freezes and deforms, and the phase change expansion of the antifreeze drives the lower semicircular groove 64 and the upper semicircular groove 65 to push upward, causing the epidermis 61 to deform concavely and convexly, as shown Figure 5 As shown, the deformation of the skin layer 61 directly acts on the ice layer 7, causing the ice layer 7 to break or reducing the ice adhesion strength, thereby preventing the ice layer from damaging the thermal insulation film 2.

[0028] Preferably, a plurality of through holes 66 are provided in the thermal insulation film 2, and the through holes 66 are arranged between two adjacent upper semicircular grooves 65. The through holes 66 increase the air permeability of the thermal insulation film 2, thereby ensuring the normal growth of flowers.

[0029] A method for using film covering to prevent weeds in intensive flower production, the specific operation steps are as follows:

[0030] Step 1: Select a flat land with less weeds, use herbicides to weed, level the land after weeding, and then renovate the land downwards to a depth of 30 cm, evenly spread the improved fertilizer on the surface of the land to a thickness of 5 cm, fertilize the soil, and cover the film 1 on the surface of the land, and continue fermenting for 24 hours;

[0031] Step 2: The prepared land is cut into holes in the film 1 according to the width of the flower planting and the spacing between plants and rows for intensive cultivation, and a number of planting grooves 8 are opened;

[0032] Step 3: Plant flower seeds or seedlings into the planting trough 8, evenly sprinkle high-quality farmyard manure and urea at a ratio of 1000:1 on the surface of the crop to apply topdressing to the plant, and then cover the surface of the film 1 with the insulation film 2 to heat and ripen the crop; when the temperature is high in summer, you can choose not to cover with the insulation film;

[0033] Step 4: When the flowers grow to a certain height, they will break out of the thermal insulation film 2. At this time, normal crop cultivation can be carried out, and the plants can be watered, fertilized and topped in time to complete the crop cultivation.

[0034] Preferably, the improved fertilizer in step one comprises decomposed organic fertilizer, corn stalk powder, oxalic acid, potassium chloride, urea, and fish pond mud, wherein 20 parts of decomposed organic fertilizer, 30 parts of corn stalk powder, 5 parts of oxalic acid, 8 parts of potassium chloride, 20 parts of urea, and 20 parts of fish pond mud are mixed, dried, and ground to obtain improved fertilizer, which can greatly improve the fertility of the soil without any pollution to the environment and can maintain the fertility of the soil.

[0035] Preferably, with respect to the above embodiment, the following plant spacing and row spacing for flower cultivation are provided:

[0036] Among them, the growth rate of ornamental grass is similar to that of weeds, but in order to ensure the growth and tillering and germination of ornamental grass seedlings, the seedbed is covered with black breathable planting film. For example, holes are cut according to the row spacing of 15cm*15cm, and the ornamental grass seedlings are planted in the weed-proof film with the holes cut. After planting, the soil is covered around the roots of the seedlings. This can make the ornamental grass seedlings grow uniformly after transplanting and reduce the cost of weed removal.

[0037] Among them, lily is a bulbous flower. When breeding edible lily bulbs, the bulbs need to be planted densely. In order to prevent weeds from affecting the expansion and nutrient absorption of the bulbs, black breathable planting film can be used. For example, holes can be cut according to the plant spacing of 10cm*10cm for planting.

[0038] Among them, succulents have thick roots, stems and leaves. When they are planted in the seedbed, in order to prevent the stems and leaves of the succulents from breaking due to manual weed removal, black breathable planting film can be used. For example, holes can be cut according to a 12cm*12cm plant row spacing to ensure that the succulents grow neatly and evenly.

[0039] Among them, cut gerbera is a perennial plant. When seedlings are planted in the open field, they are overgrown with weeds. Moreover, as they grow in the later stage, the old leaves need to be removed. Before planting the seedlings, they are covered with black breathable planting film. For example, holes are cut according to the row spacing of 20cm*20cm. When the old leaves of cut gerbera are removed in the later stage, the pathogen spores on the diseased old leaves can be prevented from falling and contaminating the soil, reducing manual weeding, keeping the bed clean and reducing the spread of diseases.
