Abstract
The utility model relates to water-pouring film used in a greenhouse. The water-pouring film is a new facility for irrigating vegetables in the greenhouse and a plastic tunnel. The utility model is mainly composed of a delivery pipe, a distributing pipe and permeable plastic film. The water flow flows on the water-pouring film from the distributing pipe through the delivery pipe. The water flows on the film, and infiltrates into the earth body arranged near the roots of the crops through certain water seepage holes (single row holes or double row holes) arranged on the plastic film under the action of gravity. Thus the deep infiltration and flow time of the water can be reduced. The water-pouring film used in the greenhouse has the advantages of heating, preservation of soil moisture, water saving, fertilizer saving, even irrigation, less investment, prematurity and yield increasing for the greenhouse crops. The water-pouring film used in the greenhouse can be used in the matrix soilless culture, and can be used for solving the problem of clogging of a dripper in a drip irrigation system.
Description
A kind of irrigating facility that is used for greenhouse and plastic tunnel.
At present greenhouse and plastic tunnel are general adopts traditional ditch, border irrigation to irrigate, but pour water cold winter in the north at every turn soil temperature is sharply reduced, and influence the vegetable crop growth, and irrigates inhomogeneously, produces deep percolation loss.Though some greenhouse adopts advanced little spray of irrigating facility and drip irrigation, big because of investing, managerial skills require high factor, influence slight irrigation large tracts of land promotion and application in the greenhouse.
The purpose of this utility model provides a kind of Plastic Film for Irrigation in Greenhouse, and it can not only improve the greenhouse irrigation condition, realizes heating, preserves soil moisture, economizes on water, irrigates evenly, and make the precocious and volume increase of crop.
The purpose of this utility model is achieved in that on the film-mulching cultivation basis, change traditional shop film mode, covering plastic thin film in ditch, is equipped with specific infiltration hole on the plastic film, its aperture is arranged in the single infiltration hole of film or apart from the double infiltration hole of crop root certain distance.Water flows to through porous pipes on the plastic film of each ditch by the water-supply-pipe water delivery, and under action of gravity, current flow on film, and near the soil body crop root is gone into to be seeped in the infiltration hole, moisture content is absorbed by crop by capillary.Owing to the water yield is easy to control, therefore flow process time weak point irrigates evenly, and plastic film gentle soil moisture conservation effect with having raising, helps plant growth.
Plastic Film for Irrigation in Greenhouse and drip irrigation structure compared are simple, low, the convenient management of investment; Compare water saving with traditional ditch, border irrigation, economize fertilizer, irrigate evenly, heat, preserve soil moisture, make the precocious and volume increase of crop.Plastic Film for Irrigation in Greenhouse is applied in the soilless culture, solved water dropper blockage problem in the substrate soiless cultivation irrigation, so Plastic Film for Irrigation in Greenhouse is the desirable surface irrigation facility of present greenhouse and plastic tunnel.
The utility model provides embodiment shown in the accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the Plastic Film for Irrigation in Greenhouse drawing in side sectional elevation.
7. double infiltration holes, 1. water-supply-pipes, 2. gate valve 3. sparge pipes, 4. apopore 5. plastic films, 6. single infiltration holes among the figure.
In Fig. 1, current are reconciled flow through water-supply-pipe (1) by gate valve (2) and are entered sparge pipe (3), flow on the plastic film (5) from apopore (4), water is gone up at plastic film (5) and is flowed under action of gravity, in the soil body, infiltration hole (6) pitch-row is determined according to crop spacing in the rows and soil property near crop root is gone into to be seeped in infiltration hole (6).
Among Fig. 2, water is gone up at plastic film (5) and is flowed, and through single infiltration hole (6) or double infiltration hole (7) infiltration, determines to adopt single infiltration hole (6) or double infiltration hole (7) according to the water demand of crop and soil property.The single infiltration of the employing that the clay and the water demand of crop are little hole (6); The double infiltration of the employing that the sand and the water demand of crop are big hole (7), infiltration aperture, hole is determined by going into film flow and soil property.
Claims (3)
1, a kind of Plastic Film for Irrigation in Greenhouse mainly comprises water-supply-pipe, sparge pipe, plastic film, it is characterized in that: sparge pipe is connected with water-supply-pipe, and the plastic film that is equipped with specific infiltration hole covers in the irrigation ditch.
2, Plastic Film for Irrigation in Greenhouse according to claim 1 is characterized in that: sparge pipe is the porous outflow tube.
3, Plastic Film for Irrigation in Greenhouse according to claim 1 is characterized in that being equipped with on the plastic film specific infiltration hole, and the infiltration hole is arranged in the single row of holes of film or apart from the double hole of root certain distance.
