Description

A siphon irrigation pipeline and an energy-saving irrigation method for crops based on the pipeline

technical field

The invention relates to an irrigation pipe for agriculture and an irrigation method.

Background technique

Irrigation is the use of water other than rainwater to grow crops and other plants. At present, the main irrigation forms are flood irrigation, sprinkler irrigation, hourly sprinkler irrigation, and drip irrigation. Flood irrigation needs to dig ditches, which wastes water resources, requires more labor, and makes you deliberately cause the groundwater table to be too high, which makes the soil salinized; it is not easy to irrigate the entire irrigation area evenly with sprinkler irrigation, and it is easy for water to flow on the leaves If there is chemical fertilizer in the irrigation water, it will cause burns on the leaves in hot and sunny weather; drip irrigation is easy to block, and in severe cases, the entire system will not work normally, or even scrapped. So how to solve the restrictive conditions of modern irrigation such as avoiding sprinkler irrigation and drip irrigation is a technical problem that needs to be solved urgently.

Contents of the invention

The technical problem to be solved by the patent of the present invention is to overcome the problem that the traditional drip irrigation emitter is easy to block and the cost is high, and to provide a method based on siphon irrigation pipe and its infiltration irrigation.

The present invention adopts following technical scheme for solving above technical problem:

A siphon irrigation pipeline, one end of the pipeline is a water diversion end, the other end is an irrigation end, and a pipe filler is included in the pipeline, and the pipeline filler is a water-absorbing material; the water diversion end pipeline adopts a PVC water pipe, and the irrigation end pipeline The pipe wall adopts permeable pipe wall.

Preferably, in the siphon irrigation pipe of the present invention, the water-absorbing material is made of highly water-absorbent fibers capable of realizing siphon phenomenon.

Preferably, in the siphon irrigation pipe of the present invention, the superabsorbent fiber adopts anti-corrosion sponge.

The present invention also provides a method for energy-saving irrigation of crops, comprising the following steps:

Step A, making a siphon irrigation pipeline, the siphon irrigation pipeline is filled with water-absorbing materials, including a water intake end and an irrigation end, the water intake end pipeline adopts a PVC water pipe, and the pipe wall of the irrigation end pipeline adopts a permeable pipe wall;

Step B, placing the water intake end of the siphon irrigation pipe completed in step A in the water intake tank, and burying the irrigation end in the roots of the crops in the soil;

In step C, when the crops are irrigated, water is injected into the water intake pool to complete the siphon type automatic irrigation.

Furthermore, in the aforementioned method for energy-saving irrigation of crops, the water-absorbing material is made of superabsorbent fibers that can realize siphon phenomenon.

The present invention adopts the above technical scheme to have the following advantages:

Water-saving: The drip irrigation system is all delivered by pipelines, and there is little leakage and evaporation loss along the way; drip irrigation is a partial irrigation, and generally only wets part of the soil near the roots of the crops during irrigation. The irrigation flow is small, and surface runoff and deep seepage are not easy to occur. In addition, drip irrigation can supply water in a timely and appropriate amount according to the needs of crop growth. Compared with other irrigation methods, the water utilization rate is higher.

Energy saving: This energy-saving irrigation method uses no external force to achieve the purpose of diverting water into the field for irrigation, which saves the energy consumption of using water pumps in irrigation. Because infiltration irrigation is more holy water than surface irrigation, the utilization rate of irrigation water is high, which is good for water-lifting irrigation. This means reduced energy consumption.

Uniform irrigation: This irrigation method can effectively control the effective use of each irrigation end, and design the pipe placement method according to their respective characteristics, so that the irrigation uniformity is high.

Specific implementation plan:

The realization of irrigation in the patent of the present invention can be divided into three steps: the manufacture of siphon irrigation pipes, the placement of siphon irrigation and the completion of irrigation.

As shown in Figures 1 and 2, one end of the pipe is the water diversion end, and the other end is the irrigation end. The pipe includes a pipe filler, which is a water-absorbing material; the water diversion end pipe is made of PVC water pipe, and the pipe wall of the irrigation end pipe is made of permeate the pipe wall.

The water-absorbing material adopts high water-absorbing fiber that can realize the siphon phenomenon, and anti-corrosion sponge or other organic water-absorbing materials can be used to achieve the purpose.

The siphon pipe is divided into a water diversion pipe and an irrigation pipe, that is, the water diversion part is completed to divert water into the field, and the irrigation part is completed to realize irrigation through the characteristics of the permeable pipe wall. After the other end is placed at the root of the soil, due to the effect of the height difference, water can be diverted into the field without external force.

As shown in Figure 3, when placing the pipe, you only need to place one end in the water intake tank, and the other end is buried in the roots of the crops in the soil, requiring a certain height difference;

The irrigation method is shown in Figure 3, which can be realized through irrigation control, that is, water is injected into the storage tank. Due to the effect of height difference, the height of the storage tank is controlled according to the amount of water required for irrigation. There is water in the storage tank, irrigation starts, and the storage tank When the reclaimed water is exhausted and the irrigation is over, water can be diverted into the field without external force.
