Irrigation device

Technical Field

The invention relates to the technical field of irrigation, in particular to a water conservancy irrigation device.

Background

Irrigation, namely watering the land with water. The irrigation principle is that the irrigation quantity, the irrigation times and the irrigation time are determined according to the water requirement characteristics, the growth stage, the climate and the soil conditions of the medicinal plants, and the medicinal plants are irrigated in a proper time and in a proper amount and reasonably. The water irrigation method mainly comprises the technical measures of irrigating water before sowing, accelerating seedling irrigation, irrigating water in a growing period, irrigating water in winter and the like, and the water required by crops is supplemented for the land. In order to ensure the normal growth of crops and obtain high and stable yield, the crops must be supplied with sufficient moisture. Under natural conditions, the water requirement of crops cannot be met due to insufficient precipitation or uneven distribution. Therefore, irrigation must be done manually to compensate for the lack of natural rainfall.

In irrigation and water conservancy irrigation, the flood irrigation mode is rural field irrigation's the leading mode of carrying on, and the flood irrigation is from the water source excavation channel, and the water source flows into in to the farmland through the channel, and if the channel is longer, the delivery channel is the soil property channel, and today at the water resource shortage, can make enlarged waste like this, and now, the water resource is extremely deficient, and the supply and demand contradiction is also outstanding day by day, and to the rational utilization of water resource, it is crucial to promote irrigation and water use rate.

In order to reduce the waste of water resources and reasonably utilize water resources, many areas adopt a drip irrigation or spray irrigation mode for irrigation, the spray irrigation technology is to spray pressurized water into the air by utilizing special equipment such as a spray head and the like to form a method for dripping water onto the surface of crops on the ground, but the spray head is laid beside the plants, so that a large amount of spray heads are needed, the spray head is positioned on one side of the plants, the inconvenience is caused for subsequent crop harvesting, and the later maintenance and viewing are not facilitated.

Drip irrigation refers to a type of irrigation in which low-pressure water is delivered to an irrigation area using special piping and equipment and slowly dripped into the soil at the roots of crops. The drip irrigation has the advantages of strong water saving, fertilizer saving and labor saving. This kind of technique can effectual improvement agricultural product's quality, but this kind of mode arouses easily to block up, has increased the trouble for the maintenance in later stage, therefore needs according to actual demand, can provide one kind and neither hinder crops to plant and reap, also can improve irrigation water rate's irrigation device.
