Embodiment 1

[0025] Example 1 The cultivation tank for highly efficient and precise adjustment of nutrient solution of the present invention

[0026] For the cultivation tank for highly efficient and precise adjustment of nutrient solution in this embodiment, the cross-section is shown in figure 1 , the structural schematic diagram of the short side with the liquid inlet and the liquid outlet is shown in figure 2 . The cultivation tank of this embodiment is a rectangular tank body, 9 meters long, 0.6 meters wide, and 0.15 meters high; the upper edges of the two long sides 1 are all rolled inward to form a groove with a gap with the long sides and an upward opening. , the top of the groove is not closed, that is, one side of the cross-section of the inward rolling part is a G shape with an opening downward, and the other side is a left and right mirror image of a G shape with an opening downward; the two grooves formed are divided into liquid inlet groove 3 and the liquid outlet groove 4...

Embodiment 2

[0032] Embodiment 2 The method of using the cultivation tank of the present invention to efficiently and accurately adjust the nutrient solution

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

[0034] Use the method for the cultivation tank of the present invention to efficiently and accurately regulate the nutrient solution, comprising the following steps:

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

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 precisely regulating nutrient solution and a method for using the same. Background technique [0002] As one of the main methods of soilless cultivation, hydroponics is widely used in the field of vegetable and flower production because of its outstanding advantages of avoiding continuous cropping obstacles, precisely controlling the composition of nutrient solution, facilitating stubble arrangement, and saving water resources and human resources. It has become an important cultivation method in the plant factory of multi-layer three-dimensional cultivation. [0003] Hydroponics usually includes pipe cultivation, nutrient liquid film cultivation, deep liquid flow cultivation, etc., all of which provide recyclable nutrient solution to plants to ensure their normal growth. Although the cultivation devices (pipes, tanks, etc.) used in the a...
