Description

Technical Field

[0001] The invention relates to the technical field of codonopsis pilosula seedling cultivation, in particular to a liquid fertilizer spraying device for garden planting. Background Art

[0002] Codonopsis seedling cultivation is mainly through sowing propagation. Select high-quality seeds, soak them for 24 hours, and then sow them in loose, well-drained soil. The sowing depth is about 1-2 cm. Cover with a thin layer of soil to keep it moist. Keep the temperature between 15-25℃ and the humidity appropriate to ensure seed germination. Regular weeding and fertilization are required during the seedling stage to prevent and control diseases and pests. It can be transplanted to the field after 6-8 months. Codonopsis prefers a shady and humid environment, and should be kept away from light during cultivation to ensure good root growth.

Placement plates are fixedly connected to the inner walls of both sides of the seedling box at equal intervals, and cultivation boxes are placed on top of each placement plate. A controller is provided on one side of the seedling box, and a wire is connected to the bottom of the controller. The tail end of the wire is connected to the soil moisture sensor, and the soil moisture sensor is located inside the cultivation box. A water tank is provided on one side of the seedling box. This patent, by installing a cultivation box, a controller, a soil moisture sensor, a water tank, a water pump, a water pipe, and a nozzle, uses an automatic water replenishment mechanism to promptly spray water on Codonopsis pilosula seedlings when water shortage is detected in the planting soil, eliminating the need for workers to constantly monitor the seedlings' condition and ensuring their normal growth. This effectively addresses the problems and shortcomings of existing devices.

[0004] However, the current seedling cultivation device has the following problems: when the seedling cultivation device is used to cultivate Codonopsis pilosula seedlings, if a large amount of liquid fertilizer is irrigated with Codonopsis pilosula, the personnel cannot discharge the excess liquid fertilizer from the cultivation box in time. The excessive liquid fertilizer will cause oxygen deficiency in the roots of Codonopsis pilosula, affect the respiration of the roots of Codonopsis pilosula, and then inhibit the growth of the roots of Codonopsis pilosula, thereby causing Codonopsis pilosula root rot. Therefore, we propose a liquid fertilizer spraying device for garden planting. Summary of the Invention

[0011] A cultivation method of a garden planting liquid fertilizer spraying device comprises the following steps:

[0012] S1. Place the cultivation box into the storage box, with the U-shaped telescopic handles placed on both sides of the storage box;

[0013] S2. Fix the fixed end of the U-shaped telescopic handle to the outer wall of the storage box through the fixing sleeve;

[0017] S6. At the same time, excess liquid fertilizer can flow into the storage box through the strip groove of the cultivation box.

[0018] The present invention provides a liquid fertilizer spraying device and method for gardening, which has the following beneficial effects:

[0019] (1) The present invention sets a water-proof device so that the motor, rotating rod, cam, cultivation box, and U-shaped telescopic handle cooperate to drive the cultivation box to swing back and forth up and down. The shaking can help the liquid fertilizer penetrate into each layer of the soil more evenly, avoid the liquid fertilizer accumulating in a certain position to cause waterlogging of the roots, and ensure that the root system of Codonopsis pilosula has a suitable moist environment. At the same time, excess liquid fertilizer can flow into the storage box through the strip groove of the cultivation box, thereby achieving the purpose of discharging excess liquid fertilizer from the cultivation box; at the same time, the cultivation box, slider, square rod, and hinged rod cooperate to drive the oblique elastic rod to loosen the culture soil in the cultivation box, so that the oblique elastic rod breaks the compaction of the culture soil, increases the gaps between the culture soil particles, helps to improve the air permeability of the soil, avoids the culture soil waterlogging and Codonopsis pilosula hypoxia caused by excessive liquid fertilizer, and after the culture soil is loosened, the liquid fertilizer can penetrate into the deep layer of the soil more evenly and quickly, avoid the liquid fertilizer accumulating on the surface, thereby reducing the influence of waterlogging on the roots of Codonopsis pilosula.

[0020] (2) The present invention sets a ventilation device so that the U-shaped telescopic handle, the cultivation box, the slider, the square rod, the slider, and the fixed plate cooperate to squeeze the folding bag, and the air in the folding bag is discharged from the one-way air outlet through the long air tube. The one-way air outlet will inject the air into the nutrient soil in the cultivation box. After the air is injected into the nutrient soil, it helps to increase the oxygen content in the nutrient soil. The root system of Codonopsis pilosula requires sufficient oxygen for respiration and metabolic activities. When there is too much liquid fertilizer, the oxygen in the nutrient soil will be exhausted, forming an oxygen-deficient environment, which will affect the growth of the root system. By injecting air, the root hypoxia can be effectively prevented, and the health and growth rate of the root system can be improved.

[0021] (3) The present invention arranges a spraying device so that the slider, the L-shaped protrusion rod, and the pressing piece cooperate to control the liquid medicine in the medicine storage box to be sprayed out from the spray head through the transmission pipe, thereby completing the spraying operation of Codonopsis pilosula. In addition, during this process, the cultivation box is shaken up and down. The shaking can promote the contact between the liquid medicine and the culture soil particles, enhance the diffusion speed of the liquid medicine in the culture soil, and make the effective ingredients more easily penetrate into the culture soil, thereby providing effective protection for the root system of Codonopsis pilosula and preventing and controlling underground diseases and pests.

After the air is injected into the nutrient soil, it helps to increase the oxygen content in the nutrient soil. The root system of Codonopsis pilosula needs sufficient oxygen for respiration and metabolic activities. When there is too much liquid fertilizer, the oxygen in the nutrient soil will be exhausted, forming an oxygen-deficient environment, which will affect the growth of the root system. By injecting air, the root hypoxia can be effectively prevented, and the health and growth rate of the root system can be improved.

[0035] When in use, the cultivation box 41 is placed in the storage box 1, and the U-shaped telescopic handle 42 is placed on both sides of the storage box 1. The fixed ends of the U-shaped telescopic handle 42 are fixed to the outer wall of the storage box 1 through the fixing sleeve 43, and the culture soil is poured into the cultivation box 41. Then, the codonopsis pilosula can be sown and propagated. When the codonopsis pilosula needs to be watered, the water pump 34 is started. The water pump 34 extracts the liquid fertilizer in the fertilizer storage tray 35 and transmits it to the water distributor 32 through the connecting pipe 33. The water distributor 32 will sprinkle the liquid fertilizer on the codonopsis pilosula. To realize the operation of watering liquid fertilizer of Codonopsis pilosula, if the amount of liquid fertilizer irrigated by Codonopsis pilosula is large, the motor 46 drives the rotating rod 44 to rotate, the rotating rod 44 drives the cam 45 to rotate, the cam 45 pushes the cultivation box 41 to move upward, and the cultivation box 41 drives the telescopic end of the U-shaped telescopic handle 42 to move upward. When the cam 45 does not push the cultivation box 41, under the elastic force of the U-shaped telescopic handle 42, the telescopic end of the U-shaped telescopic handle 42 drives the cultivation box 41 to reset and move downward, and so on, so that the cultivation box 41 shakes back and forth up and down, and shaking can help the liquid The fertilizer can penetrate into each layer of the soil more evenly, avoiding the accumulation of liquid fertilizer in a certain position to cause waterlogging of the roots, ensuring that the root system of Codonopsis pilosula has a suitable moist environment, and at the same time, the excess liquid fertilizer can flow into the storage box 1 through the strip groove of the cultivation box 41, thereby achieving the purpose of discharging the excess liquid fertilizer from the cultivation box 41; each time the cultivation box 41 moves upward, the slider 49 is subjected to the corresponding spring force, and the slider 49 will always be against the bottom of the cultivation box 41, and the slider 49 will move upward along the outside of the square rod 47, and the slider Block 49 pushes the hinged rod 410 to drive the oblique elastic rod 48 to swing slightly upward, so that the oblique elastic rod 48 loosens the culture soil in the cultivation box 41, thereby breaking the compaction of the culture soil and increasing the gaps between the culture soil particles, which helps to improve the air permeability of the soil, avoid water accumulation in the culture soil and oxygen deficiency of Codonopsis pilosula due to excessive liquid fertilizer, and after the culture soil is loosened, the liquid fertilizer can penetrate into the deep soil more evenly and quickly, avoiding the accumulation of liquid fertilizer on the surface, thereby reducing the impact of waterlogging on the roots of Codonopsis pilosula.

[0036] Each time the telescopic end of the U-shaped telescopic handle 42 drives the cultivation box 41 to reset and move downward, the cultivation box 41 will press the slider 49 to move downward along the outer wall of the square rod 47, and the slider 49 drives the fixed plate 51 to squeeze the folding bag 52, and the air in the folding bag 52 is discharged from the one-way air outlet nozzle 55 through the long air tube 54, and the one-way air outlet nozzle 55 will inject air into the nutrient soil in the cultivation box 41. After the air is injected into the nutrient soil, it helps to increase the oxygen content in the nutrient soil. The root system of Codonopsis pilosula requires sufficient oxygen for respiration and metabolic activities. When there is too much liquid fertilizer, the oxygen in the nutrient soil will be exhausted, forming an oxygen-deficient environment, which will affect the growth of the root system. By injecting air, the root hypoxia can be effectively prevented, and the health and growth rate of the root system can be improved. Each time the slider 49 moves upward along the outside of the square rod 47, the slider 49 stretches the folding bag 52 through the fixed plate 51. At this time, the folding bag 52 is aired through the one-way air inlet nozzle 53, thereby completing the replenishment of the internal air of the folding bag 52.

It should be noted that the working principle of the pressing piece 65 here is similar to that of a watering can. The pressing piece 65 is composed of a pressing part and a spring pump, so that Resetting is achieved by the action of the spring pump elastic force. A semi-arc protrusion is fixed on the outer wall of one side of the medicine storage box 61 below the L-shaped protrusion rod 64. The pressing end of the pressing piece 65 is semicircular, and the semicircular pressing end of the pressing piece 65 is located on the movement trajectory of the semi-arc protrusion of the L-shaped protrusion rod 64. Through the setting of the above structure, the pressing piece 65 controls the liquid medicine in the medicine storage box 61 to be sprayed out from the spray head 63 through the transmission pipe 62, thereby completing the spraying operation of Codonopsis pilosula, and in this process, the cultivation box 41 is shaken up and down. The shaking can promote the contact between the liquid medicine and the culture soil particles, enhance the diffusion rate of the liquid medicine in the culture soil, and make the effective ingredients more easily penetrate into the culture soil, providing effective protection for the root system of Codonopsis pilosula, and preventing and controlling underground diseases and pests.

[0038] During use, each time the Codonopsis pilosula needs to be sprayed, the medicine liquid is injected into the medicine storage box 61. Each time the slider 49 moves upward, the slider 49 will drive the L-shaped protrusion rod 64 to move upward.
