Description
Technical field
The present invention relates to proportion of crop planting field irrigation water supply and sewage technical field, especially a kind of rice farmland water-saving irrigation supply and discharge
Water installations.
Background technology
It is well known that China is the country that rice cultivation is most ancient in the world, rice made history there are about 7000, was world's cultivation water
One of rice area of origin.500,000,000 mu or so of the existing Monitoring of Paddy Rice Plant Area in China, accounts for the 30% of cereal crops sown area, is China
Staple food crop.Meanwhile China is also the country that a water resource extremely lacks, gross amount of water resources is 2.8 hundred million sides.Only account for generation
The 5.6% of boundary's gross amount of water resources is one of 13 poor-water states in the world.Heilungkiang is big agricultural province, mainly produces cereal crops.
Usual Rice Cropping is blocked up or is discharged water with soil, waste water resource, and time-consuming and laborious.With this problem, search and
It retrieved many relevant informations and find that agricultural water accounts for the 88% of national total water consumption, and rice accounts for agricultural water with water
70% or so, therefore, Study On Rice water-saving irrigation water supply and sewage method and its facility or device, the production for improving irrigation water are imitated
Rate, to ensureing that sustainable utilization of water resource, promotion national economy continue high-efficient development, realize social stability and progress etc.,
All have highly important meaning.Current water-saving irrigation research is concentrated mainly in the research of the anti-seepage of channels and irrigation program,
The former is mainly studied from the angle for how reducing water conveyance loss, and the latter is studied from the irrigation method of rice
To reduce irrigation quantity.Currently, China's Rice Cropping is planted as unit of each family mostly, when Rice Cropping, usually
It is blocked up or is discharged water with soil or knitting bagged soil, time-consuming and laborious, labor intensity is big, and woven bag is easy to aging, pollutes environment, special
Be not in water channel, sunning water pool and to divide the flow of direct current water moat infall big, it is stifled or discharge water more difficult, run, emit, seepy question more
Seriously.Although having occurred irrigation ditch gate currently on the market, most of irrigation ditch gates can not arbitrarily adjust control
The angle of check door can not thus adjust the size of control irrigation advance flow, inconvenient to use.Currently, newest statistics
Show 1,800,000,000 mu of China's cultivated area, but cultivated area occupation problem very severe, in the cultivated area of 500,000,000 mu of existing paddy field, because
Road, water channel, the floor spaces about 8-10% such as ridge, traditional branch canal（Or lateral canal）Floor space is more about 5%.Reduce arable land
Effective usable floor area.Peasant largely uses artificial during planting season row irrigation simultaneously, becomes and restricts peasant household's expansion growing surface
One of long-pending bottleneck, in addition existing paddy field or farmland lateral canal irrigation and drainage mode also result in a large amount of water moneys every year because of leakage, flood irrigation problem
Source wastes and is lost in.Therefore, a kind of rice farmland water-saving irrigation supply and discharge water installations are developed and have become urgent problem to be solved.
