Description

Technical Field

[0001] The invention relates to the technical field of seedling cultivation, and in particular to a forestry seedling cultivation device. Background Art

[0002] Trees are very important in reducing land erosion and adjusting climate. Trees can absorb carbon dioxide from the air and store a large amount of carbon in their tissues. Trees and green plants continuously carry out photosynthesis, consume carbon dioxide and produce fresh oxygen. More than 60% of the oxygen in the air comes from trees and green plants on land, so people compare trees and green plants to "oxygen factories" and "fresh air processing plants." Many trees can secrete bactericides to kill various pathogens in the air; they can also absorb toxic gases emitted by industrial production, retain smoke and dust that pollute the atmosphere, and eliminate noise pollution that is harmful to humans.

A plurality of guide members 5 are arranged on both sides of the top of the cultivation support 1, and a transmission rack 3 is slidably installed inside the guide member 5. Rectangular holes 7 matching the transmission rack 3 are arranged at both ends of the cultivation support 1. The support seats 4 on the same side rotate synchronously through the transmission rack 3. A heater 17 is installed on the inner wall of the liquid storage tank 9, and a ventilation mechanism 12 is installed inside the liquid storage tank 9. A transparent one-way valve 15 is installed between the ventilation mechanism 12 and the liquid replenishment mechanism 2. The one-way valve 15 is located on the outer side of the cultivation support 1. A cultivation barrel 13 is clamped on the top of the cultivation bracket 14, and an isolation mesh cover 8 is arranged inside the cultivation barrel 13, and the spiral tube assembly extends to the inner position of the isolation mesh cover 8.

[0020] In the present invention, a plurality of cultivation barrels 13 and isolation net covers 8 are provided for cultivating seedlings. The outer sides of the cultivation barrels 13 and the isolation net covers 8 are provided with spiral tube components, and part of the structure of the spiral tube components extends to the inner position of the isolation net covers 8. Gravel is laid on the bottom of the cultivation barrel 13, and the isolation net covers 8 are placed inside the cultivation barrel 13 and then filled with cultivation soil. At this time, part of the structure of the spiral tube components is buried in the inner position of the isolation net covers 8, and the tree species are buried in the center position of the isolation net covers 8. The liquid replenishment mechanism 2 and the ventilation mechanism 12 are used to alternately replenish nutrients for the inner part of the isolation net covers 8. Liquid and air, when the tree seeds take root and sprout, the stepper motor 6 drives the support seat 4 to rotate through the transmission rack 3, and then drives the spiral tube assembly to be gradually withdrawn from the isolation mesh cover 8. When the spiral tube assembly is withdrawn, the moisture and air distribution area in the soil inside the isolation mesh cover 8 is changed, and the water and air tropism of the root system are utilized to gradually induce the root system of the seedling to spread in a spiral shape along the direction of the isolation mesh cover 8, so as to avoid the root system of the seedling from agglomerating. Secondly, the multi-directional diffusion of the root system increases the dispersion of the root system, increases the contact area between the seedling and the soil during transplanting, and improves the survival rate of the seedling.

[0021] As a further solution in the present invention, the isolation mesh cover 8 includes a mesh cover body 81 of a cylindrical structure, and three spirally extended extensions 82 are arranged on the outer side of the mesh cover body 81, and a plurality of inner guide grooves 84 are arranged at the outer end of the extension 82.

When the tree seeds germinate, the spiral tube components are gradually withdrawn from the extensions 82 of the isolation mesh cover 8, guiding the roots of the seedlings to grow into the extensions 82 and dispersing the roots. When transplanting, the isolation mesh cover 8 is taken out of the cultivation barrel 13 as a whole. When transplanting, the three extensions 82 are simultaneously unfolded, and the seedlings are pushed to the central part of the pit under the elastic force of the extensions 82 to prevent the seedlings from tipping over or tilting. After filling, the roots extend in three directions to enhance the stability of the roots.

In the present invention, three climbing hole portions 83 are provided around the mesh cover body 81. When the roots of the tree species grow, the three climbing hole portions 83 are covered on the outside of the root system. The climbing hole portions 83 are provided with three through grooves with different apertures. When the root system of the tree expands outward, the pores attached to the climbing hole portions 83 are extended. When the mesh cover body 81 is taken out, the extension portion 82 is wrapped around the outside of the mesh cover body 81 in a spiral direction and tied. The extension portion 82 covers the outside of the climbing hole portion 83, and the root system of the seedling is wrapped in the extension portion 82, which effectively protects the root system from damage and improves the survival rate of seedling transplanting.

[0023] As a further solution in the present invention, the cultivation barrel 13 includes a barrel body 131, and a plurality of air permeable holes 133 are arranged at the bottom of the barrel body 131, and an outer guide groove 132 adapted to the spiral tube assembly is arranged on the outer side of the barrel body 131.

According to the growth cycle of the root system of the seedling, the spiral tube assembly is gradually pulled outward during the rotation movement.

[0024] As a further solution in the present invention, the cultivation bracket 14 includes a bracket body 141 installed on the side of the door-type isolation frame 11, and an annular enclosure 142 arranged on the outside of the bracket body 141. A sterilization heater 143 is installed on the top of the bracket body 141. In the present invention, after the cultivation barrel 13 is filled with soil, the sterilization heater 143 is started to heat the cultivation barrel 13, and the heat is used to sterilize and kill insects on the cultivation soil, thereby improving the survival rate of the tree species.

[0025] As a further solution in the present invention, the fluid replenishment mechanism 2 includes a delivery pump 24 installed at the bottom of the liquid storage tank 9, and a solenoid valve 25 installed at the outlet end of the delivery pump 24. The end of the solenoid valve 25 is installed with a distribution main pipe 26 connected to the one-way valve 15, and the spiral tube assembly is installed on both sides of the distribution main pipe 26 through a hose. In the present invention, when water replenishment is needed, the delivery pump 24, the solenoid valve 25 and the distribution main pipe 26 are used to distribute the nutrient solution to each spiral tube assembly. After the water replenishment is completed, the delivery pump 24 and the solenoid valve 25 are closed, and the ventilation mechanism 12 is opened to introduce air into the distribution main pipe 26, and the air is evenly delivered to each spiral tube assembly, completing the ventilation operation in the isolation mesh cover 8.

[0026] As a further solution in the present invention, the spiral tube assembly includes a triangular tube 21 arranged between the cultivation bracket 14 and the support seat 4, three vertical tubes 22 are installed on the top of the triangular tube 21, and the sides of the three vertical tubes 22 are installed with arc tubes 23 extending to the inside of the isolation mesh cover 8. In the present invention, the three arc tubes 23 are spirally distributed in the isolation mesh cover 8, and the arc tubes 23 serve as the supporting skeleton around the isolation mesh cover 8 to maintain the shape of the isolation mesh cover 8. The arc tubes 23 are used to evenly supplement nutrient solution and breathing air to the three sides of the root system during the growth stage of the seedling root system. The three arc tubes 23 are gradually pulled outward under the action of external force to guide the root system to expand in the direction of the extension part 82, and during the germination process of the tree seeds, the reciprocating motion of the arc tubes 23 is used to automatically loosen the root soil, increase the air permeability around the seeds, and further improve the seed survival rate.

[0027] As a further solution in the present invention, the ventilation mechanism 12 includes a blower 121 installed on the top of the liquid storage tank 9, and a serpentine coil 122 installed between the blower 121 and the one-way valve 15. In the present invention, the blower 121 blows air to one end of the one-way valve 15 through the serpentine coil 122. The one-way valve 15 is arranged on the outside of the device. When the one-way valve 15 is turned on, it is in an air replenishment state. When the one-way valve 15 is cut off, it is in a water replenishment state. The water replenishment and air replenishment states in the soil can be observed by the state of the one-way valve 15.

[0028] As a further solution in the present invention, the serpentine coil 122 is immersed in the interior of the liquid storage tank 9, and a plurality of vibration rods 123 are arranged below the serpentine coil 122. In the present invention, the water stored in the liquid storage tank 9 is utilized to control the temperature inside the liquid storage tank 9 to maintain a constant temperature cultivation environment inside the device. When the air is replenished, the serpentine coil 122 is immersed in the interior of the liquid storage tank 9 to adjust the temperature of the air entering the root system to maximize the respiratory activity of the root system. When the serpentine coil 122 is ventilated, the vibration rods 123 are driven to vibrate to stir the nutrient solution inside the liquid storage tank 9 to avoid precipitation of fertilizers inside, thereby improving the efficiency of fertilization and water replenishment.

[0029] When in use, gravel is laid on the bottom of the cultivation barrel 13, and the isolation mesh cover 8 is placed inside the cultivation barrel 13 and filled with cultivation soil. At this time, part of the structure of the spiral tube assembly is buried in the internal position of the isolation mesh cover 8, and the tree species is buried in the center position of the isolation mesh cover 8. The liquid replenishment mechanism 2 and the ventilation mechanism 12 are used to alternately replenish nutrient solution and air for the isolation mesh cover 8. When the tree species take root and sprout, the stepper motor 6 drives the support seat 4 to rotate through the transmission rack 3, thereby driving the spiral tube assembly to be gradually withdrawn from the isolation mesh cover 8. When the spiral tube assembly is withdrawn, the moisture and air distribution area in the soil inside the isolation mesh cover 8 is changed, and the root system of the seedling is gradually induced to spread in a spiral shape along the direction of the isolation mesh cover 8 by using the hydrotropism and gas tropism of the root system, so as to avoid the root system of the seedling from agglomerating. Secondly, the multi-directionally diffused root system increases the dispersion of the root system, increases the contact area between the seedling and the soil during transplanting, and improves the survival rate of the seedling.
