Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of agricultural equipment, especially relates to a high-cold mountainous area corn planting rain collecting and heat preserving device. BACKGROUND

[0002] In 2022, Lv Zhongyu emphasized the following points in the high-cold mountainous area corn high-yield cultivation technology: selecting hybrid seeds, selecting and preparing land, reasonable close planting, real-time sowing, mulching and strengthening field management. Among them, it is mentioned that the mulching cultivation can increase temperature, conserve soil moisture, inhibit weeds and effectively reduce the impact of disastrous weather. Artificial mulching is currently used in high-cold mountainous areas. Due to the strong wind in spring in mountainous areas, one bay is covered with one bay when mulching, and the film around the bay is compacted with the land to prevent human and animal trampling and damage to the mulch. If there is damage, it should be covered immediately. The mulch put into the field is picked up and collected in time after harvesting to prevent soil pollution.

[0003] The above document records that mulching has the functions of increasing temperature, conserving soil moisture and inhibiting weeds, but does not mention the problem of rain collection. Irrigation facilities are lacking in high-cold mountainous areas, and artificial irrigation is time-consuming and labor-intensive, so a device that uses mulching to collect water and increase soil moisture is needed to combine the two. UTILITY MODEL CONTENT

[0004] The utility model aims at solving the defects of the prior art, and provides a high-cold mountainous area corn planting rain collecting and heat preserving device which realizes the functions of heat preservation and rain collection by using mulching.

[0005] The utility model adopts the following technical scheme:

[0006] A high-cold mountainous area corn planting rain collecting and heat preserving device, the device comprises a shed pole, a transparent heat preservation film and a film pressing rope, the shed pole is inserted on both sides of the ridge surface of the land block, the transparent heat preservation film is covered on the shed pole, the transparent heat preservation film is compacted with soil at the contact position to form a closed space, the transparent heat preservation film is pierced at the contact position, the film pressing rope is arranged along the middle part of the shed pole and perpendicular to the shed pole, the transparent heat preservation film is pressed down, the both ends of the film pressing rope are fixed in the soil on both sides, and a top film hole is formed at the position corresponding to the seed sowing hole of the transparent heat preservation film.

[0007] Further, the black mulch is covered on the seed sowing hole, the seed sowing hole is punched in the land block, and a hole is formed at the position corresponding to the seed sowing hole covered by the black mulch.

[0008] Further, the shed pole is in the shape of " " and has a recess at the top.

[0009] Further, the recess is provided with a top film hole.

[0010] Further, a shed pole is arranged every 100 cm parallel to the ridge, and the height of the shed pole is 0.4 m.

[0011] Further, the diameter of the top film hole is 1 cm.

[0012] The utility model discloses the beneficial effect:

[0013] 1. The present application solves the problem of poor climate in high-cold mountainous area, long-term low temperature, little light, cold, and insufficient accumulated temperature, which causes many crops to be unable to grow. By using and popularizing the device, the utilization efficiency of abandoned cultivated land resources in high-cold mountainous area can be improved, and corn lodging can be prevented.

[0014] 2. The black mulch film can suppress weeds and quickly absorb light and heat. The lamp-like seed sowing hole can collect the rainwater leaked from the transparent heat preservation film hole and the rainwater flowing into the seed sowing hole along the plant after the seedling emerges from the film, and the rainwater can infiltrate into the soil. The black mulch film can lock the water in the soil for a long time, and achieve the effect of water retention.

[0015] 3. The transparent heat preservation film can fully transmit sunlight, and the black film can quickly absorb light and heat to increase the ground temperature while blocking the temperature loss in the shed, so that the effect of long-time heat preservation is achieved. The top hole of the film can not only collect rainfall, but also regulate the temperature and humidity in the film (when the temperature is too high, the hole can be used as a heat dissipation hole for hot air, so that seedling burning is avoided), and can also block the freezing damage of low temperature and cold wind to the crop seedling stage.
