Abstract

The utility model discloses a PVC (polyvinyl chloride) aquiculture pipeline with an elliptic cross section and belongs to the field of the facility horticulture. The aquiculture pipeline comprises an elliptic pipe body, a water return pipe and a water inlet pipe, wherein planting holes with diameters of 1.2-2.5 cm are arranged at intervals of 10-25 cm along one side of the top of the axis of the elliptic pipe body; the water return pipe is arranged at the bottom of one end of the elliptic pipe body and penetrates into the elliptic pipe body to be perpendicular to the axis of the elliptic pipe body; and the water inlet pipe is arranged at the side part of the other end of the elliptic pipe body to be perpendicular to the water return pipe. The aquiculture pipeline is used for culturing vegetables, thereby being more beneficial to the growth of roots of the vegetables and expanding of growing space of the roots and saving the PVC consumable.

Description

A kind of water planting pipeline

Technical field

The utility model belongs to the facilities horticulture field, and being specifically related to a kind of cross section is oval-shaped PVC water planting pipeline.

Background technology

At present, the vegetables hydroponic device that is used for using in horticultural facilities such as greenhouse or booth mainly contains: slot type (as DFT, NFT etc.), bed surface formula, duct type, column type etc.With regard to the duct type hydroponic device, mainly adopt the draining or the feedwater piping of civilian PVC material, assemble by glue and conduit coupling, be not specifically designed to the pipeline of nutrient fluid cultivation.

The draining of civilian PVC material or feedwater piping, its cross section is circle, and the general nutrient solution degree of depth therein accounts for the 1/2-2/3 of caliber, and its complementary space is an air.Though this planting type can allow the vegetable plant of the more anti-weak oxygen of some root systems grow, but usually the phenomenon of Chu Xianing is that the root system colors of vegetables is darker, be brown, white root system and tiny fine hair root system seldom, this has been the performance of root system of plant anoxic in fact.In order to solve top problem, also can enlarge the contact area of root system of plant and air simultaneously, having designed the cross section is oval-shaped PVC water planting pipeline.

The utility model content

At present vegetables water planting more and more by people accepted, cultivated area is increasing, and existing water planting pipeline has root system and the air contact area is little, the easy oxygen and produce the problem of brown stain for want of of root system, and it is oval-shaped PVC water planting pipeline that the utility model provides a kind of cross section.

A kind of water planting pipeline is characterized in that, described water planting pipeline is made up of oval body 1, liquid back pipe 2 and feed tube 3; Along top one side of oval body 1 axis, every the distance of 10-25cm, leaving diameter is the field planting hole 4 of 1.2-2.5cm; Liquid back pipe is installed in the bottom of oval body 1 one ends and gos deep into its inside, perpendicular to oval body 1 axis; Feed tube 3 is installed in the sidepiece of oval body 1 other end, perpendicular to liquid back pipe 2.

Described oval body 1 length is 5-7 rice, and the oval cross-section major axis is 16-25cm, and minor axis is 7-15cm, and major axis is 1 with the length ratio of minor axis: (0.4-0.6), and thickness of pipe wall 1.5-2.5cm.

The height that liquid back pipe 2 gos deep into oval body 1 is 4-5cm.

The beneficial effects of the utility model: 1, adopt oval pipeline after, the PVC material of use still less, so cost is lower, more economical.2, the contact area of ducted liquid level and air is bigger, thereby the dissolved oxygen amount in the nutrient solution can be more, more helps the growth of root system.3, root system is in oval-shaped major axis position, and root system will have bigger space development growth.

Fig. 2 is the field planting hole schematic diagram;

Fig. 3 is the utility model water planting pipeline general illustration;

Fig. 4 is the scheme of installation of liquid back pipe in oval body;

Wherein, the oval body of 1-, 2-liquid back pipe, 3-feed tube, 4-field planting hole, φ D-major axis, φ d-minor axis, φ M-field planting hole diameter.

Embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described further:

Embodiment 1: utilize oval water planting pipeline, plant romaine lettuce in greenhouse by solar heat

The oval water planting pipeline (Fig. 3) of present embodiment is made up of oval body 1, liquid back pipe 2 and feed tube 3; Along top one side of oval body 1 axis, every the distance of 20cm, leaving diameter phi M is the field planting hole 4 (Fig. 2) of 2cm; Liquid back pipe is installed in the bottom of oval body 1 one ends and gos deep into its inside, perpendicular to oval body 1 axis, highly is 5cm (Fig. 4) deeply; Feed tube 3 is installed in the sidepiece of oval body 1 other end, perpendicular to liquid back pipe 2; Oval body 1 length is 7 meters, and major axis φ D is 20cm, and minor axis φ d is 12cm, thickness of pipe wall 2cm, and its cross section is as shown in Figure 1.

Field planting hole 4 is used for the field planting romaine lettuce; Liquid back pipe 2 is used for ducted nutrient solution is drawn back the nutrition liquid pool, and its height that gos deep into oval body 1 is controlled the depth of liquid level in the pipeline; Feed tube 3 is used for the nutrient solution in the nutrition liquid pool is introduced oval body, its liquid inlet and field planting hole 4 homonymies.

It should be noted last that, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
