Abstract

The utility model relates to a water-saving drip irrigation pipe for a mountain land film. The water-saving drip irrigation pipe for the mountain land film is that a rain collecting field, a desilter, and a reservoir which are mutually communicated are built on a cultivated land, and the interiors of the rain collecting field, the desilter, and the reservoir are paved with anti-seeping materials, which makes the ground surface runoff water in a pluvial period is collected and stored. The lower side of the reservoir is connected with a water-draining pipe by a connecting disk. A water flow control valve is arranged on the water-draining pipe. The outlet of the water-draining pipe is connected with a plastic drainage pipe. Drip irrigation pipes which are inserted into the mountain land film and are provided with a plurality of heads are respectively connected on the plastic drainage pipe by three-way pipes. Current controllers are respectively arranged on the drip irrigation pipes.

Description

Mountain field above film water-saving drip irrigation tube

Technical field

The utility model belongs to the technological improvement that the mountain region is irrigated, and is specifically related to a kind of mountain field above film water-saving drip irrigation tube.

Background technology

Along with the enforcement of country to west area conceding the land to forestry (grass) policy, the agricultural structure of North Shaanxi and planting technology are also adjusted and are improved, under the guidance of government, with past 15-25 ℃ based on the plantation hillside fields of crops and the narrow terraced fields of part kind of the grass of conceding the land to woods comprehensively, minimizing along with the per capita area of cultivated farmland of conceding the land, the ever-increasing pressure of population, people are more and more higher to the agricultural planting output requirement of unit are, and agricultural planting has to pursue high production with the input of new technologies and methods.But loess plateau, northern Shensi water is the main restricting factor of agricultural, the local area natural precipitation is less, average annual rainfall 400-450mm, and spatial and temporal distributions inequality, 60% above rainfall concentrated on 7-9 three months, with crop growth phase serious dislocation, drought and water shortage has become the major obstacle of restriction northern Shensi conceding the land to forestry policy execution and agricultural sustainable development and social progress.In order to obtain the grain high yield in unit are, government subsidy has developed a large amount of cellar for storing things kiln collection rain agriculturals, because cellar for storing things kiln building cost height lacks the high-efficiency water-saving irrigation technique again, cellar for storing things kiln rainwater collection project only can solve arid area human livestock drinking water problem, is difficult to be applied to field irrigation.

Summary of the invention

In order to overcome the deficiency of existing irrigation technique, the scheme that the utility model solves, be to utilize hillside fields, production road, garden or roof etc. to repair Ji Yuchang, sedimentation basin and the storage cistern of establishing intercommunication on the top of cultivated land, and lay impervious material within it, make the rainwash water collection storage in rich Pluvial, water with storage cistern drains into irrigated land with plastic flexible pipe then, be connected to the threeway drainage tube on the aqueduct, the outlet of this pipe is connected to drip irrigation pipe respectively, and connects a water quantity controller on each drip irrigation pipe.Because film ridge, mountain region is uneven, aqueduct pocket current pressurized on film is irregular, and high and low place dripping irrigation water flow velocity is unbalanced, and the available water quantity controller that is connected on the drip irrigation pipe is regulated and reached even drip irrigation.

Advantage of the present utility model: the one, rain collecting water storing can reduce the water and soil loss that local plot rainwash causes, and greatly improves the ecological environment; The 2nd, the water source of drip irrigation is to utilize natural precipitation fully on the film, utilize the hillside fields nature discrepancy in elevation that water is directly guided to the production land used again, irrigate with drip irrigation pipe, do not need power from collection rain, water storage to water conveying and drip irrigation overall process, so water saving, power saving, take things easy, production-increasing function is remarkable, has good social benefit and economic benefit; The 3rd, drip head is a plastic flexible pipe, can insert when dripping under the film, and water is directly delivered to plant root, does not destroy the surface soil structure after the irrigation, keeps soil from packing together, and the interstices of soil rate is higher by 25% than flood irrigation, and soil aeration is good, helps plant growth.

Description of drawings

The utility model embodiment is illustrated by the following drawings.

Fig. 1 is the utility model overall structure schematic diagram.

Embodiment

By mountain field above film water-saving drip irrigation tube shown in Figure 1, be to utilize the hillside fields on the top of cultivated land, the production road, the Ji Yuchang (1) that establishes intercommunication is repaiied on garden or roof etc., sedimentation basin (2) and storage cistern (3), and lay impervious material within it, make the rainwash water collection storage in rich Pluvial, the downside of storage cistern is connecting aqueduct (6) by tie-plate (4), water flow control valve (5) is housed on the aqueduct, outlet is connecting plastics drainage tube (7), can be connected to a plurality of tributary pipes (10) respectively by three-way pipe (8) on this drainage tube, water flow control valve (9) is housed on the pipe of tributary, and connecting the bull drip irrigation pipe (13) of insertion mulch film (12) by a plurality of threeways (11) of being equipped with, water flow controller (14) is housed respectively on this drip irrigation pipe, because film ridge, mountain region is uneven, aqueduct pocket current pressurized on film is irregular, high, lower dripping irrigation water flow velocity is unbalanced, and the available water quantity controller that is connected on the drip irrigation pipe is regulated and reached even drip irrigation.

Claims

1, a kind of mountain field above film water-saving drip irrigation tube, be by Ji Yuchang, sedimentation basin, storage cistern, aqueduct, water flow control valve and bull drip irrigation pipe are connected to each other composition, it is characterized in that: utilize the hillside fields to repair on the top of cultivated land and establish the Ji Yuchang (1) of intercommunication, sedimentation basin (2) and storage cistern (3), and lay impervious material within it, make the rainwash water collection storage in rich Pluvial, the downside of storage cistern is connecting aqueduct (6) by tie-plate (4), water flow control valve (5) is housed on the aqueduct, outlet is connecting plastics drainage tube (7), can be connected to a plurality of tributary pipes (10) respectively by three-way pipe (8) on this drainage tube, water flow control valve (9) is housed on the pipe of tributary, and connecting the bull drip irrigation pipe (13) of insertion mulch film (12) by a plurality of threeways (11) of being equipped with, water flow controller (14) is housed respectively on this drip irrigation pipe.
