Embodiment 1

[0025] Example 1 The cultivation tank of the present invention for efficiently and accurately regulating nutrient solution

[0026] The cultivation trough for high-efficiency and precise regulation of nutrient solution of this embodiment is shown in cross section figure 1 , The structure diagram of the short side with the liquid inlet and the liquid outlet is shown in figure 2 . The cultivation trough of this embodiment is a rectangular trough with a length of 9 meters, a width of 0.6 meters and a height of 0.15 meters; the upper edges of the two long sides 1 are rolled inward to form a groove with a gap with the long sides and opening upwards , The top of the groove is not closed, that is, one side of the cross section of the inner roll part is a G-shaped opening downward, and the other side is a left and right mirror image of a G-shaped opening downward; the two grooves formed are divided into the liquid inlet groove 3 And the liquid outlet groove 4, a short side of the groov...

Embodiment 2

[0032] Example 2 Method of using the present invention to efficiently and accurately adjust the nutrient solution cultivation tank

[0033] Refer to Example 1 for the cultivation tank used in this example for high-efficiency and accurate nutrient solution adjustment.

[0034] The method of using the present invention to efficiently and accurately adjust the nutrient solution cultivation tank includes the following steps:

[0035] Start to infuse the nutrient solution so that it flows into the liquid inlet groove 3 through the liquid inlet 6 along the liquid inlet pipe. When the liquid inlet groove 3 is filled, the nutrient solution flows down the edge of the liquid inlet groove 3 in the form of a water curtain and is poured into the cultivation On the bottom of the tank, when the liquid level is raised to the edge of the outlet groove 4, the nutrient solution is poured into the outlet groove 4 in the form of a water curtain in a short time, and flows out from the outlet pipe through ...

Abstract

The invention provides a cultivation tank capable of high-efficiently and accurately regulating nutrient solution. The cultivation tank is a cuboid tank, the upper edges of two long side faces are inwards coiled to form grooves which reserve gaps with the long side faces and are opened upwards, the tops of the grooves are not closed, namely one side of the cross section of the inward coiling part is G-shape which is downwards opened, and the other side is a left and right mirror image of the G-shape which is downwards opened; two formed grooves are a liquid feeding groove and a liquid discharging groove, one short side face of the tank is provided with a liquid inlet and a liquid outlet which are respectively connected with a liquid feeding pipe and a liquid discharging pipe, the liquid inlet and the liquid outlet are respectively aligned to the liquid feeding groove and the liquid discharging groove, and the liquid inlet is higher than the liquid outlet slightly. The invention further provides a using method for the cultivation tank capable of high-efficiently and accurately regulating nutrient solution. The cultivation tank is used so that the circulation process of the nutrient solution in the cultivation tank is changed from the original longitudinal flow along the length to the transverse flow along the width, the flow distance is greatly shortened, the whole cultivation tank is injected with the nutrient solution at the same time along the edges of the liquid discharging groove in the manner of water screen, and the nutrient solution can be uniformly replaced during the short time.

Description

Technical field [0001] The invention relates to the field of facility cultivation, in particular to a cultivation tank for efficiently and accurately regulating nutrient solution and a method of use thereof. Background technique [0002] As one of the main methods of soilless cultivation, hydroponics is widely used in vegetable and flower production because of its outstanding advantages such as avoiding continuous cropping obstacles, accurately controlling the nutrient composition, facilitating cropping arrangements, and saving water and human resources. It has become an important cultivation method in plant factories with multi-layer three-dimensional cultivation. [0003] Hydroponics usually includes pipe cultivation, nutrient liquid film cultivation, deep flow cultivation and other methods, all of which ensure the normal growth of plants by providing circulated nutrient solutions. Although the cultivation devices (pipes, tanks, etc.) used in the above various hydroponic methods...
