Abstract
The invention discloses an irrigation area canal system suitable for water culture of the Tibetan region. The system comprises a water source, a main canal, branch canals, and a drainage system of a field irrigation region, wherein the water source is communicated with the main canal and is arranged at a high place; the main canal is communicated with the drainage system via the branch canals; the irrigation area canal system also comprises wetland system; the wetland system is communicated with the main canal and the drainage system via the branch canals; closure gates are respectively arranged at the joint of the wetland system and each branch canal and the joint of the drainage system and each branch canal. The irrigation area canal system disclosed by the invention has the advantages of effectively increasing the utilization rate of water, increasing the irrigation area and realizing high yield and stable yield of agriculture. After irrigation return water is accumulated and stored by utilizing engineering measures, drainage systems which are mutually communicated in series are used for sending water to fields and lands, which is quite beneficial for dispersedly-flowing water lifting facilities and water lifting irrigation, so the water irrigation period is greatly shortened. After the irrigation return water is developed and utilized in the downstream of the irrigation area, water is saved for maximum proper irrigation of the upstream farmlands, so water contradiction of the upstream and downstream is mitigated.
Description
Technical field
The present invention relates to irrigation and water conservancy field, particularly relate to the irrigated area canal system of a kind of applicable Tibetan area aqueous culture.
Background technology
Water resources shortage has been global problem, the key constraints of water arid and semi-arid area agricultural production especially.The recycling of waste water and recycling are the effective ways solving this contradiction.Return water could be used further to irrigate or other aspects, the composition of harmful substances and concentration contained by return water and determine.
The planning principles of general irrigation canal system is: 1) trunk canal is arranged in eminence, to control larger area; 2) arrange make engineering quantity and engineering cost minimum; 3) consider administrative division, use water unit and channel as far as possible independently; 4) lateral canal, field ditch meet mechanized farming requirement; 5) comprehensive utilization of water resource is considered; 6) irrigation canal system is arranged and must be combined with arrangement of Drainage; 7) irrigation canal system and land use planning match, to improve land utilization ratio, and convenient production and life.
Tibetan area is mainly distributed in arid and semi-arid area, generally dry and rainless, and climate change makes China's Arid&semi-arid area water resource spatial and temporal distributions uneven, and the contradiction of supply and demand for the water resource is given prominence to.China's Arid&semi-arid area generation agricultural arid number of times is increase trend, and agricultural arid greatly constrains China's Arid&semi-arid area agricultural development.
The principle of China's semiarid zone agricultural water resources Appropriate application should be that effective maintenance of water and the efficiency utilization of water are laid equal stress on, and " maintenance " is prerequisite, and " utilization " is crucial.Solve semiarid zone agricultural water shortage problem and and then the key link realizing limited water resources efficiency utilization be agricultural water conservation.Therefore, the combination collecting rain supplement irrigation and modern dry farming is the inevitable choice of semiarid zone agricultural development.The common difficulty that the water-saving irrigation of semiarid zone and dry farming and water-saving irrigation will be captured how to improve utilization rate and the utilization ratio of natural precipitation and irrigation water.
Summary of the invention
Object of the present invention is just to provide one to solve the problem, and is the efficient technique of rainwater utilization approach realizing semiarid zone agricultural limited water resources, is applicable to the irrigated area canal system of Tibetan area aqueous culture by raising farmland rainwater use efficiency and utilization ratio.
To achieve these goals, the technical solution used in the present invention is: the irrigated area canal system of a kind of applicable Tibetan area aqueous culture, comprise water source, trunk canal, branch canal and be positioned at the drainage system in field irrigation district, described water source is communicated with trunk canal, and being arranged in eminence, described trunk canal is communicated with drainage system by branch canal, also comprises wet land system, described wet land system is communicated with trunk canal and drainage system by branch canal, and the junction of described wet land system, drainage system and branch canal is equipped with the gate that dams.
As preferably, described wet land system is between water source and field irrigation district.
As preferably, the branch canal be connected with wet land system has two, and described two branch canal are respectively inlet channel and outlet canal, and described inlet channel and outlet canal are equipped with the gate that dams.
As preferably, described inlet channel is positioned at wet land system top, and outlet canal is positioned at wet land system bottom.
As preferably, described wet land system has multiple, and described multiple wet land system is communicated with branch canal respectively.
Compared with prior art, the invention has the advantages that: the present invention effectively can improve the utilization rate of water, brings more land under irrigation, realize high yield, the stable yields of agricultural.The surface runoff utilizing the gate that dams that rainfall can be made to produce is unlikely to be pooled to the same period in downstream, alleviates water drainage burden, rainwater storage can also be utilized simultaneously.After having poured water, according to the situation such as weather, crop water, the irrigation return flow of remainder can be stored.After utilizing works measure stores irrigation return flow, by the heat-extraction system of mutually ganging up, water is delivered to field, the extracting water facility being very beneficial for dispersion flows launches irrigation by pumping simultaneously, and irrigation frequency is shortened dramatically.After downstream, irrigated area develops irrigation return flow, vacate the water yield and the farmland of upstream can be made in good time to obtain farthest irrigating, what alleviate upstream and downstream uses water contradiction.
