Description
Technical field
The utility model belongs to water-saving irrigation technique field, particularly relates to a kind of greening seedling shallow embedding formula irrigation and drainage facility.
Background technology
China's water resource spatial and temporal distributions is extremely uneven, and along with population increase, the raising of economic development and the level of urbanization, the contradiction of supply and demand for the water resource is becoming increasingly acute, agricultural arid lack of water and shortage of water resources have become the important restriction factor of China's economy and social development, therefore, Development of Water-Saving Irrigation technology is extremely urgent.
Water-saving irrigation technique mainly comprises engineering and agronomic technique, and water-saving irrigation project technology refers to that the water yield reduced in irrigation canal system (pipeline) water delivery process is evaporated and filter loss, improves the technology of the utilization rate of farmland irrigating water.Mainly comprise (1) channel seepage technique, be water penetration for reducing channel or set up not easily permeable overcoat and every technical measures of taking, soil compaction, tabia mask, masonry lining, cement lining can be divided into according to the material used, plastic sheeting is anti-blends pitch mask antiseepage etc.; (2) low-pressure pipe irrigation technology, is called for short " pipe filling ", is a kind of irrigation method utilizing low pressure pipeline to replace channel hydraulic pipeline." pipe filling " one-time investment is few owing to having, equipment is simple, than native canal water-saving 40%, saving of labor, province ground, save time, and yield increase effect is remarkable, and peasant is easy to the advantages such as grasp, is quite paid attention to; (3) sprinkler irrigation technique, is utilize special equipment to be sprayed onto by press water to form fine liquid particles in the air, and drops to the irrigation method in field equably, and obvious advantage of spraying is poured water evenly, accounts for arable land less, saves manpower, to the strong adaptability of landform.Major defect is large by wind effect, and equipment investment is high; (4) drip irrigation technique, drip irrigation technique is the soil moisture needed for plant growth and various nutrient are transported to timely and appropriately near crop root, has significant water saving, effect of increasing production; (5) infiltration irrigation technology, infiltrating irrigation is after sprinkling irrigation, drip irrigation, a kind ofly novel effectively descend irrigation technique, under the condition meeting plants physical growth demand, directly irrigated changing into the irrigation in soil in the past root system of plant, domestic at present have low pressure infiltrating irrigation and gravity infiltrating irrigation two kinds of modes.Because infiltrating irrigation ubiquity seepage hole was easy to blocking, the problems such as the field uneven, the gradient is larger should not adopt of pouring water in the past, the development of infiltrating irrigation once met obstructions; (6) rainwater catchment utilizes technology, is in arid, semiarid Mountainous Areas, the surface runoff produced is collected compared with Heavy rain, and supply the technology of crop utilization when needing most.Water-saving irrigation agronomic technique mainly contains Crop Regulated Deficit Irrigation technology, crop Controlled root divided alternative irrigation technology, improves Ground Irrigation Techniques, the shallow wet solarization irrigation technology of Rice Thin, irrigation with saline water technology.Through years of researches and Demonstration And Extension, China's water-saving irrigation technique has had significant progress, but water-saving irrigation technique to apply difficulty still very large, being not only technical problem, is much socioeconomic problem in addition.
Field drainage measure mainly contains gutter drainage system and covered conduit (pipe) drainage system, current main application for gutter drainage system, there is obvious shortcoming in gutter drainage, excavation project amount greatly, is easily subsided, deposit, take up an area many; Closed drainage is with the obvious advantage, is mainly to take up an area few, be conducive to tractor-ploughing, without caving in, manageability, quantities is little, but shortcoming to be cost high, one-time investment is large.
Research about greening seedling draining irrigation rig and technology also has a lot of reports, a kind of water saving water supply facility of planting trees as Ruan Tai state utility model, a kind of Water-saving desert forestation device of gentle and quiet utility model, bang worships a kind of big tree transplanting draining of utility model gas permeable devices, a kind of arbor Day water irrigating device of Hu Hongjun utility model etc., these devices, to fresh-water-saving resource, improve efficiency of water application, prevent waterlogging disaster from having obvious effect.But sub-irrigation, the research of oozing row are also weak, ubiquity seepage hole are easy to blocking, the problem such as uneven of pouring water, and by also rare for the device that draining is integrated with irrigation.
Utility model content:
The utility model, for the deficiencies in the prior art, provides a kind of shallow embedding formula subdrainage irrigation rig, can effective fresh-water-saving resource when the utility model is irrigated, raising efficiency of water application; During draining, the generation of waterlogging disaster can be prevented.The utility model can significantly improve plant percent, and solve seepage hole be easy to blocking and uneven problem of pouring water.
The utility model for achieving the above object,
A kind of greening seedling shallow embedding formula irrigation and drainage facility, it is characterized in that: have tank and sump, tank connects sump by pipeline, water distributor between sump connected row, water distributor connects each district's seepage ring.
Wherein in the ranks water distributor: be divided into supervisor, arm and side pipe, predominant tube diameter 4-6cm, one end connects tank and sump, other end connecting branch; Arm in the ranks distributes along tree, diameter 3-5cm, and the left and right sides is connected with side pipe; The all corresponding side pipe of every one tree, tube diameter 2-3cm, is connected with root district seepage ring.Supervisor, arm, side pipe and root district seepage ring, underground buried depth is 20-30cm, and at same level line.
Wherein root district seepage ring is made up of soakaway trench and threeway, soakaway trench is connected with two delivery ports of threeway, form ring-type, lay around tree well edge, soakaway trench has inside and outside two-layer formation, and internal layer is diameter 2-3cm, be covered with and have PPR, PE of water seepage hole or the tubing of rubber, outer for thickness 0.5-1cm, seep water the effective and anti-blocking filtering layer of not easily degrading, threeway inlet opening is connected with water distribution side pipe, and delivery port is connected with pipe two ends in soakaway trench.
Beneficial effect:
Drought and water-scarce area water scarcity, evaporation is large, and afforestation water requirement is large again, therefore develops water-saving forest planting method and seems particularly necessary.The utility model effectively can improve WUEL, reduces moisture evaporation, fresh-water-saving resource, and effectively can solve seepage hole blocking and uneven problem of pouring water.Meanwhile, rainy season, rainfall was more concentrated, and easily produce waterlogging disaster, this device also can discharge field excessive moisture, avoided root system to cause nursery stock dead by waterlogging.
