Enlightenment of agricultural development in Israel to other arid areas.

Israel's drip irrigation technology is in a leading position in the world. Its drip irrigation equipment can supply water 1 liter to 20 liters per hour, and the highest water utilization rate can reach 95%, which is very suitable for fine planting. For example, the low-flow drip irrigation nozzle used for soilless culture often consumes a lot of water for fine planting in greenhouse, while the drip irrigation system designed for greenhouse application uses low-flow nozzle, and the water supply is only 200 ml per hour. This method is unique.

80% of irrigated land in Israel is irrigated by water and fertilizer, which can complete irrigation and fertilization at the same time. Israel has developed a drip irrigation head for wastewater irrigation, which can control the flow of water and prevent clogging. The drip irrigation pipeline produced in Israel is equipped with a filter element, which is a plastic multi-tooth element. When the water flows through the filter cylinder, it will generate vortex, which will throw away the dust particles in it and prevent the narrow outlet of the drip irrigation head from being blocked.

(2) Underground irrigation technology

Israel has derived a new irrigation method from drip irrigation technology, that is, buried irrigation with a pipeline buried 50 cm underground. This irrigation method can keep the surface dry, and even irrigation will not affect the field work. In this buried drip irrigation system, a material called Tarplan is used, which can prevent the root growth near the emitter, thus preventing the drip irrigation system from being penetrated by tiny roots. When the water valve is closed and irrigation is stopped, the valve of the drip irrigation system will be opened to fill the pipeline with air to prevent foreign dust from being sucked into the drip irrigation head. A variety of drip irrigation emitters have been developed, such as pipeline emitters, adjustable and non-adjustable fixed emitters, and centralized emitters pre-cast on the wall of drip irrigation pipe.

(3) Sprinkling irrigation technology

In this way, each tree can be watered with a separate sprinkler. Israel has also developed a series of sprinkler supporting products mainly used for orchard and greenhouse irrigation. The water consumption of sprinkler irrigation is about 30-300 liters per hour. This irrigation method can make the effective utilization rate of water reach 85%.

Distributed irrigation technology

Spreader is mainly designed for irrigation of field crops, because this irrigation method is suitable for large-scale irrigation. Using the spreader can make the water utilization rate reach 70%-80% (traditional open irrigation, the water utilization rate is only about 40%).
