Technical field
The present invention relates to the water-saving fields of field irrigation, and specifically farmland underground, which fills, seeps water-saving new technique.
Background technique
China is the country of a water resources shortage, and water resources quantity per mu is about the 1/2 of world average level, per capita water
Stock number only has the 1/4 of world average level, and is distributed imbalance, it can be seen that the water volume that can be utilized in China is lower.Its
In as North China (Beijing, Tianjin, Hebei, Shandong, the Inner Mongol) water resources quantity account for the whole nation 4.54%, population and GDP difference
The 19% and 24% of the whole nation is accounted for, but water resource economics belong to the area of water resource critical shortage more than 70%,
With socio-economic development, water requirement increases, and the contradiction of supply and demand for the water resource will protrude increasingly.
In China's water total amount, 70% belongs to agricultural water, the north up to 80%, and the 90% of agricultural water is to irrigate to use
Water.About 400,000,000,000 m of China's agricultural irrigation year water consumption3, water efficiency of irrigation only has 0.3-0.4, the irrigation water of well-irrigated area
Also there was only 0.6 or so with coefficient, irrigation water waste is serious, if irrigation water usage factor is improved 10%, every year may be used
Save more than 400 hundred million m3。

Technology, sprinkler irrigation technique, micro irrigation technology.
Channel seepage technique is to reduce and prevent to penetrate into the water-saving technology that canal bed is lost water by channel, is that China's agricultural is total
The agriculture of water consumption 80% fills main water delivery means and channel.
Low-pressure pipe irrigation technology is to replace water delivery Tu Qu that water is straight using low pressure main conduits such as plastics or concrete
Field irrigation crop is picked, which is to reduce the technical measures that water occurs to leak and evaporate during transportation.
Sprinkling irrigation is a kind of mechanization efficient water-saving irrigation technology, it pressurizes or utilize water water using special equipment
Pressure water is sent to irrigated plot by natural-drop, is ejected by spray head and is dissipated into tiny water droplet in the air, is evenly distributed in field
Between irrigated.But sprinkling irrigation is affected by the wind, and big, evaporation loss is big, energy consumption, one-time investment is big, operation is difficult and may go out
The disadvantages of existing soil bottom moistens deficiency influences, these disadvantages limit the development of sprinkler irrigation technique.
Micro irrigation technology is the water for having pressure conveying to be assigned to field, by douche with small using irrigation system
Flow moistens a kind of local irrigation technique of soil near crop root.Slight irrigation can substantially be divided into trickle irrigation, microspray irrigation, tubule fill and
Four kinds of infiltrating irrigation.Primary disadvantage is that water outlet is uneven, water outlet is easily blocked, and high investment, and keeps it a wide range of for slight irrigation
It promotes.
