Embodiment 1

[0025] Such as Figure 1-3 As shown, this embodiment provides a fruit and vegetable hydroponic tube, including a lumen 100, the lumen 100 is integrally formed by connecting the upper, lower, left, and right side plates end-to-end to form an isosceles trapezoid with a radial cross-sectional shape that is narrow at the top and wide at the bottom. structure. In addition, the radial cross-sectional shape of the lumen 100 of the present invention may also be other shapes, such as ellipse and the like.

[0026] The top wall of the lumen 100 is provided with a liquid inlet hole 11 for matching with the end of the nutrient solution supply tube and several planting holes 12 axially spaced along the top wall of the lumen 100 . In this embodiment, the liquid inlet hole 11 is arranged at one end of the long axis of the lumen 100, and the other end of the long axis of the lumen 100 is provided with a liquid outlet, and the several planting holes 12 are arranged at intervals in the liquid ...

Embodiment 2

[0030] Such as figure 1 , 4 As shown in , 5, this embodiment provides a fruit and vegetable hydroponic tube, including a lumen 100, the lumen 100 is integrally formed by connecting the upper, lower, left, and right side plates end-to-end to form a radial cross-sectional shape that is narrow at the top and wide at the bottom. Waist trapezoidal structure. In addition, the radial cross-sectional shape of the lumen 100 of the present invention may also be other shapes, such as ellipse and the like.

[0031] The top wall of the lumen 100 is provided with a liquid inlet hole 11 for matching with the end of the nutrient solution supply tube and several planting holes 12 axially spaced along the top wall of the lumen 100 . In this embodiment, the liquid inlet hole 11 is arranged in the middle of the lumen 100, the two ends of the long axis of the lumen 100 are respectively provided with liquid outlets, and the several planting holes 12 are arranged at intervals in the liquid inlet h...

Abstract

The invention discloses a fruit and vegetable water cultivation pipe, and an even flowing control method of a nutriment solution in the water cultivation pipe. A plurality of shallow grooves parallel to a long axis of a pipe cavity are formed in the bottom surface width direction of the pipe cavity of the water cultivation pipe at intervals; a solution feeding hole matching a tail end of a nutriment solution supplying pipe is formed in a top wall of the pipe cavity, and a plurality of planting holes are axially formed in the top wall of the pipe cavity; and even flowing grooves communicating with the shallow grooves in the width direction are formed in a bottom surface of the pipe cavity between the solution feeding hole and the adjacent planting hole. In the early stage of nutriment supplying, the nutriment solution falls into expanding grooves and evenly flows in the width direction of the pipe cavity, when the liquid level reaches to the shallow grooves, the nutriment solution flows to the shallow grooves and are evenly conveyed to all the plants in the axial direction, and in this way, the problem that in the early stage of nutriment supplying, even distribution of nutriment solution exists in different root positions of the same plant and between different plants in the conventional water cultivation pipes can be solved, and the utilization rate and the distribution evenness of the nutriment solution can be greatly improved in the supplying early stage.

Description

technical field [0001] The invention relates to the technical field of soilless cultivation, in particular to a method for controlling the uniform flow of fruit and vegetable hydroponic tubes and nutrient solutions in the hydroponic tubes. Background technique [0002] At present, plant hydroponic devices used in horticultural facilities such as greenhouses or greenhouses mainly include: trough type (such as DFT, NFT, etc.), bed type, pipeline type, column type, etc. As far as pipeline hydroponic devices are concerned, drainage or water supply pipes made of PVC material for civil use are mainly used. The drainage or water supply pipes made of PVC material for civil use are all round or oval in cross section. 1 / 2-2 / 3, but on the one hand, this kind of hydroponic tube is easy to cause hypoxia in the root system of the plant, and the root system is darker, brown, with few white roots and fine fluffy roots. On the other hand, this round tube or The radial middle of the elliptic...
