Some crops, such as tobacco, need to be subjected to drip irrigation under a film during planting, and the drip irrigation under the film is a novel water-saving technology. The drip irrigation technology under the film has the advantages of saving irrigation water, high fertilizer utilization rate, obvious yield increasing effect, low labor cost and low engineering cost.

Mulching film, i.e., ground covering film, is usually a transparent or black PE film, and is used for ground covering to increase the temperature of soil, maintain the moisture of soil, maintain the structure of soil, prevent pests from attacking crops and diseases caused by certain microorganisms, etc., and promote the growth of plants.

Drip irrigation belts are used for local irrigation by sending water to the roots of crops through orifices or drippers on capillary tubes with the diameter of about 10mm by using plastic pipes. Through a very small inflow of the outflow opening, a drip emitter or drip tape, the water is dripped, drop by drop, uniformly and slowly into the soil near the root of the crop.

In the process of implementing the utility model, the inventor finds that at least one of the following problems exists in the prior art:

1. the drip irrigation tape or the drip irrigation capillary is covered with a layer of mulching film, and the working procedure is not simplified enough.

Detailed Description

The following description is made with reference to the accompanying drawings and a specific embodiment.

In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings of the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention. Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the utility model, as claimed, but is merely representative of selected embodiments of the utility model.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

See fig. 1-6. The drip irrigation mulching film described in the embodiment comprises a mulching film 100 and a drip irrigation film with the same length as the mulching film 100. In this embodiment, the number of the drip irrigation films is two, and the drip irrigation films are the first drip irrigation film 200 and the second drip irrigation film 300, and the first drip irrigation film 200 and the second drip irrigation film 300 are arranged below the mulching film 100 in parallel. The mulching film 100 is provided with a plurality of planting holes 101, and the planting holes 101 are positioned between the first drip irrigation film 200 and the second drip irrigation film 300. The planting holes 101 are closed holes, namely the planting holes 101 are closed holes in a normal state, films on the planting holes are processed in advance through cutting and scribing, and the planting holes 101 can be easily torn when plants are transplanted. The planting hole 101 interval can set up according to the row plant spacing of different plants, for example flue-cured tobacco planting density, row spacing 120cm, plant spacing 50cm, single file ridging, the width of drip irrigation plastic film refers to the width of ridge, and planting hole 101 interval is flue-cured tobacco plant spacing 50 cm. Of course, the planting distances of different crops are different, and the distance of the planting holes 101 is preset according to the planting modes of different plants, so that the popularization of the standard planting mode is facilitated, and the planting technology of farmers is improved.

The first drip irrigation film 200 is disposed in the same manner as the second drip irrigation film 300. In this embodiment, the manner of disposing the second drip irrigation film 300 will be described in detail.

In this embodiment, the second drip irrigation film 300 is attached to the lower surface of the mulching film 100 in parallel, and forms a drip irrigation belt with the mulching film 100. Drip irrigation holes are formed in the drip irrigation belts and are located below the mulching film 100. The drip irrigation holes may be small holes directly pierced in the second drip irrigation film 300, or may be the drip irrigation flow paths 301 as described in the present embodiment.

Specifically, two long sides of the mulching film 100 are connecting parts 310, and the connecting parts 310 are connected with the mulching film 100. The drip irrigation flow channel 301 is disposed between the mulching film 100 and the connection part 310. The drip irrigation flow channel 301 is a curved path, so that the resistance of the flow channel to fluid is increased, and the uniformity of the drip irrigation speed of the drip irrigation belts in different sections is facilitated. The drip irrigation flow path 301 is printed on the connection portion 310 area by embossing in advance, and then the connection portion 310 is connected with the mulching film 100.
