Example 3
The main roots and the lateral roots of the broussonetia papyrifera seedlings are increased in length and quantity along with the gradual growth of the broussonetia papyrifera seedlings, the main roots and the lateral roots are soaked in the nutrient solution for a long time under the condition that the height of the culture solution is unchanged, and because the solubility of oxygen in the nutrient solution is limited, in order to ensure that the main roots and the lateral roots of the broussonetia papyrifera can absorb more oxygen, part of the main roots and the lateral roots generally need to be lifted above the nutrient solution, so that the oxygen is directly absorbed by the part of the main roots and the lateral roots to increase the oxygen absorption amount of the broussonetia papyrifera, and the sound growth of the broussonetia papyrifera is facilitated. For this reason, the relevant parts of the device are further improved.
As shown in fig. 2, a distance measuring sensor 19 is arranged on the outer wall of the sliding base 3, a scale 21 corresponding to the distance measuring sensor 19 is arranged on the single box 8, and the distance measuring sensor 19 measures the distance from the sliding base 3 to the scale 21 and transmits the distance to the controller; the height of the distance measuring sensor 19 is not higher than that of the scale 21, so that the distance measuring sensor 19 can smoothly measure the distance from the distance measuring sensor 19 to the scale 21.
When a paper mulberry is cultured in a nutrient solution, the diameter of a trunk of a paper mulberry seedling gradually becomes thicker along with the growing of the paper mulberry seedling, the trunk of the paper mulberry tree extrudes the fixed ring sleeve 5, the branches 4 and the push seat 2 through the rubber convex pad 7 on the fixed ring sleeve 5 and the rubber convex pad 7 on the upper end of the electric telescopic rod 6 to drive the sliding seat 3 to move, when the sliding seat 3 moves outwards, the sliding seat 3 drives the distance measuring sensor 19 above the sliding seat 3 to move outwards, so that the distance measuring sensor 19 is close to the scale 21, the distance from the distance measuring sensor 19 to the scale 21 is gradually reduced, the diameter of the trunk of the paper mulberry is gradually increased at the moment, the number and the length of main roots and side roots of the paper mulberry are correspondingly increased, and the demand of the paper mulberry for oxygen is increased at the moment; in order to increase the amount of oxygen absorbed, on one hand, when the sliding base 3 moves, the sizes of the staggered holes are reduced and the discharge amount of the oxygen is reduced according to the description in the embodiment 2, so that the oxygen is retained in the seedling raising box 12 to the maximum extent and sufficient oxygen is provided for the main roots and the lateral roots; on the other hand, when the distance value measured by the distance measuring sensor 19 received by the controller is reduced, the controller starts the electric telescopic rod 6 to extend, and then pulls the trunk of the paper mulberry through the rubber convex pad 7 at the upper end part of the electric telescopic rod 6 to drive the paper mulberry to move upwards, and controls the height of the upward movement of the paper mulberry by controlling the extension length of the electric telescopic rod 6 and the depth of the culture solution, so that part of main roots and side roots of the paper mulberry can be lifted out of the nutrient solution and exposed to the air with higher oxygen content, and thus, part of the main roots and the side roots can directly absorb oxygen, the absorption amount of the paper mulberry to the oxygen is increased, the problems that the oxygen supply amount is insufficient due to limited oxygen solubility in the nutrient solution and the healthy and strong growth of the paper mulberry is influenced are solved, the growth speed and quality of the paper mulberry are increased to the greatest extent, and the effect is remarkable.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
