Water-saving and water-retaining environment-friendly mulching film

Abstract

The utility model belongs to the technical field of agricultural mulching film equipment, and particularly relates to a water-saving and water-retaining environment-friendly mulching film, which comprises a mulching film provided with a plurality of water inlet films and a plurality of planting holes. By arranging the water inlet film, when manual water irrigation or natural rainfall occurs, due to the fact that the water inlet film framework opens the upper end of the water inlet film bag, water flow can enter in a one-way mode, obstruction caused by water permeation is avoided, and then uneven humidity and water waste are avoided; in the non-irrigation time, the water inlet film is naturally closed under the action of gravity, so that water infiltrated under the film can be retained, and reverse osmosis evaporation is controlled; air enters the mulching film along with water in the irrigation process, so that respiration of root systems of crops can be ensured, and adverse effects on the root systems are avoided; the longitudinal tensile strength of the mulching film is basically the same as that of a conventional mulching film, and the normal manual mulching or mechanical mulching process is not affected.

Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural mulch film equipment, in particular to an environmentally friendly mulch film that saves water and retains water. Background Art

[0002] Mulch can effectively reduce soil moisture evaporation, maintain soil moisture, extend crop growth cycles, save irrigation water, and enable crops to thrive even in drought conditions. In addition, mulch can also increase soil temperature, promote early growth of crops, reduce soil erosion, improve soil structure, and effectively inhibit weed growth and reduce the occurrence of pests and diseases.

[0003] However, traditional mulch uses drip irrigation tape under the film, which is only suitable for well water. It will hinder the penetration of river water, rainwater and other irrigation methods, and cannot fully utilize the water outside the film, resulting in uneven humidity and water waste; it will also compress the soil and affect root development, hinder soil gas exchange, and affect root health.

[0004] Therefore, it is necessary to design a water-saving and water-retaining environmentally friendly mulch film that can be used for irrigation with well water, river water and rainwater at the same time, and will not hinder water penetration, avoid uneven humidity and water waste, so as to reduce its adverse effects on crop growth. Utility Model Content

[0005] In response to the existing problems, the utility model provides an environmentally friendly mulch film that saves water and retains water, aiming to solve the problems mentioned in the background technology that the existing mulch film will hinder water penetration, cause uneven humidity and water waste, and will compress the soil and thus affect root development, hinder soil gas exchange, and affect root health.

[0006] In order to solve the above problems, the utility model provides an environmentally friendly water-saving and water-retaining mulch film, including a mulch film, on which a plurality of water inlet membranes are arranged, and a plurality of planting holes are opened on the mulch film and between the water inlet membranes. The water inlet membrane includes water inlet holes arranged on the mulch film, the lower end of the water inlet holes is connected to a water inlet membrane frame, and the lower end of the water inlet membrane frame is connected to a water inlet membrane bag.

[0007] Furthermore, the water inlet membranes and the planting holes are arranged in rows, and each row of water inlet membranes and each row of planting holes are arranged at intervals.

[0008] Furthermore, the water inlet membrane frame props up the upper end of the water inlet membrane bag.

[0009] Furthermore, the upper end of the water inlet membrane bag is connected to the water inlet hole through the water inlet membrane frame, and the lower end of the water inlet membrane bag is an opening.

[0010] Furthermore, the ground film and the water inlet film bag are both black PE films.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The utility model sets a water inlet membrane. When artificial irrigation or natural precipitation occurs, the water inlet membrane skeleton holds the upper end of the water inlet membrane bag open, so that water can enter in one direction, avoiding obstacles to water penetration, thereby avoiding uneven humidity and water waste; during non-irrigation time, the lower end of the water inlet membrane bag closes naturally under the action of gravity, so that the water that infiltrates under the membrane can be retained and reverse osmosis evaporation can be controlled.

[0013] 2. In the utility model, during the irrigation process, air enters the inside of the ground film along with water, which can ensure the breathing of the crop roots and avoid adverse effects on the root system; at the same time, it has a certain cooling effect. In spring or seasons with lower temperatures, the local film has the same heat preservation and warming effect as the conventional ground film. In midsummer and high temperature seasons (temperature>35°C), the ground temperature under the local film is lower than that under the conventional ground film.

[0014] 3. The longitudinal tensile strength of the ground film of the utility model is substantially the same as that of conventional ground films, and does not affect the normal artificial or mechanical covering process. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The water inlet membranes 2 and the planting holes 3 are arranged in a row, and each row of water inlet membranes 2 and each row of planting holes 3 are arranged at intervals.

[0025] The water inlet membrane frame 202 props up the upper end of the water inlet membrane bag 203 .

[0032] Among them, by setting up the water inlet membrane 2, in the non-irrigation state, the lower end of the water inlet membrane bag 203 is naturally closed under the action of gravity, which can retain the water that infiltrates under the membrane and control reverse osmosis evaporation; and when artificial irrigation water or natural precipitation occurs, the water inlet membrane skeleton 202 holds the upper end of the water inlet membrane bag 203 open, so that water can flow in from the water inlet hole 201, and the water opens the lower end of the water inlet membrane bag 203 and enters the interior of the ground film 1, avoiding obstruction to water penetration, thereby avoiding uneven humidity and water waste; at the same time, during the irrigation process, air enters the ground film with water, which can ensure the breathing of crop roots and avoid adverse effects on the roots; in spring or seasons with lower temperatures, local films have the same heat preservation and warming effect as conventional films. In midsummer and high temperature seasons (temperature>35°C), the ground temperature under the local film is lower than that under the conventional film.
