Israel- water owned by the state Agriculture Irrigation Technology advanced

things in the world can not do without water, most of our people do not have to worry about drinking water, and then for some countries in the world, the water is extremely valuable, Israel is one of them. Since a large area of ??desert land, less annual rainfall, water is extremely scarce in Israel, but Israelis simply by virtue of advanced science and technology, to overcome the difficulties of water shortage. my country is the lack of water resources in the country, Israel's water-saving irrigation techniques and ideas are worthy of our deep reflection and learning.

Israel: all water is a national agricultural water-saving irrigation advanced technology (picture from the network)

water as a public resource use quota system [123 ]

because of the extreme water shortage, after the founding of Israel as a strategic water resources belong to the state, to ensure water security has naturally become a top priority of successive governments. Also it proved to unified management of national water resources policy, to ensure the proper protection and efficient use of limited water resources, Israel's success on the road to modern ecological agriculture of the premise.

Israel in 1959 to develop the "Water Law" in the ownership, management rights and other mining rights and national water resources, made detailed provisions. According to this law, the country's water resources in the public domain, using the unified allotted by the State, any unit or individual shall not be allowed to exploit. The Act also specifically provides water resources on private land also belongs to the public. Israel subsequently enacted a series of water-related laws and regulations, "Act well," "River Law."

According to these provisions, digging wells and rainwater retention are required to apply to the government and pay the appropriate taxes, well depth and quantity of water per year are required for approval. Over the years, these laws are strictly fulfilled in practice, provides a legal guarantee for the development of water-saving agriculture.

Israel's National Water Commission is responsible for the centralized management of water resources. Water Authority addition to developing national water policy on the macro, but also responsible for regulating the price of water, allocating water resources, soil protection, pollution prevention and waste recycling and reuse and so on. In addition to the water committee, there is an "inter-ministerial committee" to assist in the development of water resources, supervision, management and use of. Israel's National Water Wastewater responsible for the country's three large urban agglomerations and water recycling.

Water Authority water annually quota allocated to the collective farm village or the country, then the farmAssigned to the farmer or village, the quota will be cut during every drought. Quota system in favor of farmers on agricultural production and long-term planning, including the selection of crops and determine acreage and so on. With the support of the quota system is a ladder-type water. Israel will be divided into natural fresh water, desalination of seawater, saline groundwater, recycled water (waste water recycling) and intercept rainwater and several other categories, different types of water prices. In the water quotas, tariff divided into three levels, the excess water would have been heavily fined.

clear legal system, strict water quotas and water price ladder, after a long practice, the majority of farmers in Israel established a strong awareness of water conservation. According to a survey of the Israeli Water Commission show that since 1989 quotas, most farmers used up the annual water quota.

to develop the total amount of agricultural water saving irrigation technology significantly decreased

Israelis continue to study and promotion of new water-saving technologies and equipment, and proposed a "watered crops instead of watering the soil," the advanced irrigation concept. Israeli engineers in the 1960s invented the drip irrigation technology, which opened an irrigation technology revolution.

is a pressure drip irrigation techniques, have other advantages unmatched irrigation methods: First, a significant saving of water directly to the root crop through a pressure tube, can greatly reduce the amount of evaporation; second applicable strong, since the uniform amount of each dripper drip tube on the same side, even in terraces, steep topography and a greater distance can also be used, and do not contribute to soil erosion; three integration can be achieved fertilizer, manure added water, through the plant roots directly emitter, substantial increase in utilization of fertilizer, fertilizer effect is equally remarkable; Fourth available desert subterranean salt water or brackish water treated drip irrigation, the water contained in the salt solution around the roots of crops stay close to the accumulation of other issues, making it possible to brackish water for irrigation; Fifth, avoid fertilizer contamination of deep groundwater, and reduce weed growth.
