Description
Technical field
This utility model relates to irrigation of paddy fields water saving art field, is specifically related in a kind of paddy soil
Moisture Control facility.
Background technology
Oryza sativa L. is to need water crops, and the paddy growth of hydropenia will be affected, but the rice field water yield
It is not The more the better yet, on the one hand waste water resource, on the other hand affect the growth of Oryza sativa L.,
Keep rational water layer extremely important to the potentiality playing rice yield at different period of duration.?
The a lot of irrigation methods occurred in conventional farming operation, such as intermittent irrigation, aerobic irrigation etc. all
Be according to growth period duration of rice needed for the water yield irrigate.On the one hand these irrigation methods improve
The utilization ratio of farmland irrigating water, on the other hand plays the climatic environment of reply high temperature and little rainfall
Rice field water-saving, the effect of Scientific irrigation；But these irrigation methods are all surface irrigation, a side
Face is uneven due to rainfall spatial and temporal distributions, and the implementation of these irrigation methods is affected greatly by weather, another
Aspect is substantially flat owing to being difficult in rice field to accomplish, field pipe-net is difficult to uniformity, to irrigation
The application of method also functions to certain inhibition.
Water consumption in China agricultural accounts for the 70% of whole nation total water consumption, reaches 400,000,000,000 m3
Above, and at present Farmland Water utilization rate and WUEL all ratios of China are relatively low, wherein
The utilization rate of farmland irrigating water is averagely only 40%～45%, and the utilization ratio of farmland irrigating water is only
There is 1.0kg/m3Left and right, well below developed country 70%～80% and 2.0kg/m3Above level.
And Oryza sativa L. is the cereal crops that China is main, planting widely distributed, long-term sown area is about
2867km2, Oryza glutinosa annual production about 1.8 hundred million t, account for the 29% of Grain in China agricultural crop sown area respectively
With the 40% of total grain output, and during Rice Production, water consumption is huge, accounts for agricultural water
70%, even if in the southern china Oryza sativa L. main producing region of water resource relative abundance, water resource is to Oryza sativa L.
The restriction effect produced is also apparent from.Current global irrigated area major part is surface irrigation,
In order to make traditional surface irrigation improve the utilization rate of irrigation water equally, save irrigation water, state
The most mainly change fill continuously as Surge Irrigation on border, accelerate water flow velocity in irrigation ditch, subtract
Few current filter loss in irrigation ditch.External another water saving advanced person in terms of Surface irrigation
Technology is exactly that laser is leveled land, and makes the highness change in whole plot within 2～3cm.Cross
The technology such as laser is smooth, pulse is poured water, tail water recycling improves field and infiltrates the uniformity and realize
Water saving.Japanese Rice water-saving irrigation technique emphasizes that early stage is based on dew, middle and late stage shallow irrigation knot
The former positive irrigation method closed and covering with ground sheeting dry farming etc..India is many employing Oryza sativa L. in terms of rice water-saving
Intermittent irrigation technology.But Mountain In China complexity is various, Land leveling technology can difficult large-area applications.
Intermittent irrigation serves water saving effect on very great achievement face, but compared with external water-saving irrigation,
Irrigation water using efficiency is the lowest.So, use pond (field) end pipe laying, pond (field) head
Irrigation method at the bottom of the ponds such as upper water-retention connection, allow irrigation water from penetrating into surface soil at the bottom of pond, native
Earth effectively absorbs, and loss and the transpiration of irrigation water are greatly decreased, and can not only accurately control rice field institute
Need water layer, moreover it is possible to improve water using efficiency, reach water-saving and yield-increasing effect.

Go out following several Rice irrigation new techniques and method, and promoted in larger area and succeed.
(1) shallow wet dry irrigation.The shallow wet alternate of tiller early stage, jointing-booting stage, full heading time, often
Secondary pour water 30～50mm, pour water again during to face, field no water layer；Tiller later stage dry field；Milk stage
Shallow, wet, dry, solarization replaces, and after pouring water, water layer is 10～20mm deeply, drops to soil moisture content
Pour water again to about the 80% of field capacity；The yellow phase cuts off the water, and naturally falls dry.(2) Surge Irrigation
Irrigate.Period of seedling establishment keep 20～60mm water layers, tiller later stage dry field, yellow maturity falls dry, remaining time
Between take shoaling layer, irrigation method that open field (no water layer) is alternate.(3) semi dry is irrigated and (is controlled
Irrigate).After turning green or after tiller early stage, water management uses no water layer to irrigate, with
Root layer soil moisture content, as Con trolling index, determines irrigation period and irrigating water quota.(4) aerobic
Irrigate.Master according to rice plant of tillering stage and Spike development to the formation of these two rice roots in florescence
Want period, implement " three water three wet one dry " water management pattern.Be i.e. " very little water cutting seedling,
Very little water fertilizing and weeding controls worm, and very little water booting is bloomed, moistening moisture tiller, moistening water ear differentiation,
Moistening water Grain Filling, field control tiller is done in enough Seedling drainings " water management method.(5) " three droughts "
Water-saving culture.Use dry rice seedling, drought wholely and the management of land for growing field crops drought, within after seedling three days, fill a water,
Even filling twice, keeps ground moistening after turning green, and i.e. fills if being spaced not rainfall in 7～10 days during this
Water, each mu is poured water 30m3, filling 2～3 times after heading, 6-8 time altogether, land for growing field crops, the year of great drought fills 10
Secondary.(6) Dry seeded rice.Under the situation of nonirrigated farmland, live, non-irrigated length in seedling stage, middle and late stage utilize rainwater
A kind rice method of water requirement is needed meeting rice strain with suitably irrigating.(7) rice mulching cultivation.
Based on transplanting rice, the material of covering has straw and mulch film two kinds, and the method for plantation is according to covering
The difference of material of lid and different, with covering with ground sheeting, punching transplanting after covering.Use straw
Cover, can be before transplanting or after transplanting.(8) paddy drought seedling.Dry farming seedbed is used to cultivate
Rice shoot, it has water-saving, saving of labor, province's kind, province rice seedling bed, abridged edition, increases production, the advantage such as increases income.
Reasonably irrigation method, not only reduces frequency of irrigation and duty, decreases
Between evaporation and field seepage is ecological and transpiration water consumption.But flatness and the soil due to rice field
Loamy texture ground and by problems such as weather are affected, need water water layer accurately to control there is certain difficulty, lead
Cause irrigation water using efficiency and crop water productivity ratio still exists certain gap compared with abroad.
Irrigation method intermittent irrigation in the current Rice Production of China, wetting irrigation for paddy field, aerobic filling
Irrigate, semiarid cultivation etc., these irrigation practices have played the biggest work to saving Rice Production water
With, but all of irrigation method is all by irrigation canals and ditches, enters land for growing field crops, uses ground flood irrigation, fills
Irrigate efficiency of water application low, and need abundance water source and the supporting of irrigation canals and ditches just can carry out.And fill
Irrigating water many, evaporation seepage is many, waste water resource, irrigates efficiency of water application the lowest；Irrigation water is few,
The soil moisture uniformity is inconsistent, and such as irrigation canals and ditches engineering aging, one meets arid, without irrigation water
Oryza sativa L. hydropenia is caused in source, and plant diminishes, setting percentage reduction, mass of 1000 kernel decline, Biomass and product
Amount reduces, and causes the Oryza sativa L. underproduction even to be had no harvest.Overflow accordingly, it would be desirable to new irrigation method solves ground
Fill the problem that efficiency of water application is the lowest.Therefore, new irrigation method is needed season at paddy growth
Controlling water layer, the problem of solution soil water-containing uniformity has become those skilled in the art and has needed
Solve the technical problem that.
