Description

Technical Field

[0001] The embodiments of the present invention belong to the technical field of hydroponic equipment, and specifically relate to a hydroponic strawberry planting device and method. Background Art

[0002] At present, strawberry cultivation at home and abroad is mainly based on greenhouse soil cultivation. Due to the influence of climate, continuous cropping of land, etc., it is difficult to achieve year-round production, and pests and diseases are serious, and product quality and output are difficult to guarantee. With the rapid development of facility agriculture, soilless cultivation technology is becoming more and more widely used. Facility agriculture + soilless cultivation technology can achieve high yield and high quality of plants, which can increase production by 2 to 3 times compared with ordinary traditional cultivation; at the same time, it can ensure the balance of water and nutrients, and is a water-saving cultivation mode; it can achieve hygienic cleaning of the planting environment and fruits, and reduce pests and diseases; during the cultivation process, it can reduce the cultivation process, save labor, and realize modern technical operations. Therefore, facility agriculture + soilless cultivation technology meets the development requirements of modern agriculture.

[0003] In the field of strawberry cultivation, the main planting forms of facility agriculture + soilless cultivation technology are rectangular trough NFT hydroponics and trapezoidal trough substrate culture. At this stage, the cultivation of strawberries in my country is still mainly based on substrate cultivation, and only a small part of it is based on nutrient solution hydroponics. Among them, the substrate cultivation technology uses the substrate as a fixed substance in the process of plant growth, and mainly uses nutrient solution as nutrient supply. The planting system is complex. In addition, in order to save costs, growers repeatedly use the substrate, which greatly increases the incidence of strawberry diseases and pests. It is difficult to achieve true hygiene and cleanliness in the planting environment. The use of nutrient solution hydroponics for strawberries can solve these problems because the site is better selected and the nutrient solution can be replaced at any time. However, whether it is rectangular trough NFT hydroponics or trapezoidal trough substrate cultivation, the roots of strawberries are completely immersed in water or buried in the substrate, and the ventilation and respiration of the roots are very difficult, resulting in many root diseases and the quality and yield of strawberries are still difficult to guarantee.

[0040] The hydroponic strawberry planting device 100 according to the present invention comprises a planting trough 10 and a planting plate 20, wherein the planting trough 10 cooperates with the planting plate 20, and the planting trough 10 has a receiving chamber 101 for receiving nutrient solution, and a liquid supply hole 102 is provided at the bottom of the planting trough 10, and the liquid supply hole 102 is connected with the receiving chamber 101, so that the nutrient solution is pumped into the receiving chamber 101 through the liquid supply hole 102, and a liquid return pipe 11 is also provided at the bottom of the planting trough 10, and the liquid return pipe 11 connects the receiving chamber 101 with the outside of the planting trough 10, so that part of the nutrient solution in the receiving chamber 101 is discharged through the liquid return pipe 11. The arrangement of the liquid supply hole 102 and the liquid return pipe 11 can realize the replacement of the nutrient solution in the receiving chamber 101 and the conversion of the liquid level. A plurality of planting grooves 21 are also provided on the planting plate 20, and the planting grooves 21 are used to place strawberry plants. Along the height direction of the hydroponic strawberry planting equipment 100, the bottom plate of the planting groove 21 is located above the liquid return port 111 of the liquid return pipe 11, that is, there is a certain distance between the bottom plate of the planting groove 21 and the liquid return port 111. The strawberry plant is located in the planting groove 21, and the root of the strawberry plant extends into the accommodating cavity 101 through the hole in the bottom plate of the planting groove 21. The root system located between the bottom plate of the planting groove 21 and the liquid return port 111 is exposed to the air, and part of the root system below the height of the liquid return port 111 is located in the nutrient solution, that is, an air layer is formed between the bottom plate of the planting groove 21 and the liquid return port 111, and the root system of the strawberry plant is partially located in the air and partially located in the nutrient solution, thereby ensuring ventilation, respiration and nutrient supply of the strawberry root system, reducing diseases of the strawberry root system, and improving the product quality of the strawberry plant.

[0041] In addition, the present invention also has the following advantages:

[0042] 1. The planting environment of pure hydroponic mode produces clean and sanitary fruits;

[0043] 2. The planting environment is clean, the roots of the strawberry plants are well ventilated, and the nutrient solution has a high concentration of dissolved oxygen, making it difficult for the strawberry plants to be susceptible to diseases and insect pests;

[0044] 3. The roots of strawberry plants absorb water fertilizer and air fertilizer alternately, and the combined effect makes the nutrition of strawberry plants more balanced;

[0045] 4. Achieve early maturity and increase yield of strawberries to ensure fruit quality;

[0046] 5. Pure hydroponics avoids continuous cropping obstacles and ensures year-round production;

[0047] 6. The nutrient solution is recycled to save energy and reduce investment and operating costs;

[0048] 7. The strawberry plant process operates scientifically and intelligently, which is conducive to the mechanization and intelligence of strawberry planting.

[0049] In some embodiments of the present invention, the hydroponic strawberry planting device 100 further includes: an anti-overflow structure, which is arranged in the planting trough 10, and is located above the liquid return port 111 along the height direction of the hydroponic strawberry planting device 100. When the liquid level of the nutrient solution in the accommodating chamber 101 rises to the position of the anti-overflow structure above the liquid return port 111, the anti-overflow structure can control the electromagnetic valve of the liquid supply hole 102 to be closed through the controller, and at the same time, part of the nutrient solution in the accommodating chamber 101 is discharged to prevent the nutrient solution from entering the planting trough 21 from the hole at the bottom of the planting trough 21.

[0050] In some embodiments of the present invention, along the height direction of the hydroponic strawberry planting equipment 100, the anti-overflow structure is located below the planting groove 21 to ensure that the liquid level of the nutrient solution in the accommodating chamber 101 is always lower than the bottom of the planting groove 21, preventing the nutrient solution from entering the planting groove 21 from the bottom of the planting groove 21.

[0051] In the first embodiment of the present invention, the hydroponic strawberry planting equipment 100 also includes a controller (not shown in the figure), and the overflow prevention structure includes an electronic liquid level meter 31, which is electrically connected to the controller, and the controller is electrically connected to the electronic valve of the liquid supply hole 102 (not shown in the figure). When the nutrient solution level in the accommodating chamber 101 reaches the position of the electronic liquid level meter 31, the electronic liquid level meter 31 alarms and transmits the information to the controller, and the controller controls the electronic valve of the liquid supply hole 102 to close, controls the power supply of the constant pressure water pump to close, and controls the electromagnetic valve on the pressure-dividing drainage branch (not shown in the figure) of the liquid supply pipeline of the liquid supply hole 102 to conduct pressure-dividing drainage. When the nutrient solution level in the accommodating chamber 101 is at the intermittent liquid level 120, that is, when the nutrient solution level is at the height of the liquid return port 111 of the liquid return pipe 11, the electronic valve of the liquid supply hole 102 can be controlled by the controller to open, and the nutrient solution is pumped into the accommodating chamber 101 through the liquid supply hole 102 by the constant pressure variable frequency water pump.

[0052] In the second embodiment of the present invention, the anti-overflow structure includes an anti-overflow port 32, which is provided on the side wall of the planting trough 10, and is located between the bottom plate of the planting trough 21 and the liquid return port 111, and the anti-overflow port 32 connects the accommodating chamber 101 with the outside of the hydroponic strawberry planting device 100. When the liquid level of the nutrient solution in the accommodating chamber 101 rises to the height of the anti-overflow port 32, that is, when it rises to the anti-overflow water level, the nutrient solution overflows from the anti-overflow port 32 to ensure that the liquid level of the nutrient solution in the accommodating chamber 101 does not rise to the bottom plate of the planting trough 21, thereby reducing the influence of the nutrient solution on the strawberry plants in the planting trough 21.

[0053] In the third embodiment of the present invention, the overflow prevention structure includes an overflow prevention pipe 33, which is connected to the liquid return pipe 11 and is arranged at the top of the liquid return pipe 11. Specifically, the axis of the overflow prevention pipe 33 coincides with that of the liquid return pipe 11, and the overflow prevention pipe 33 and the liquid return pipe 11 have the same size and shape. An overflow prevention port 32 is arranged at the top of the overflow prevention pipe 33, and the overflow prevention port 32 is connected to the inner cavity of the overflow prevention pipe 33. When the liquid level of the nutrient solution in the accommodating chamber 101 rises to the height of the overflow prevention port 32 at the top of the overflow prevention pipe 33, that is, when the liquid level of the nutrient solution rises to the overflow prevention water level, the nutrient solution enters the inner cavity of the overflow prevention pipe 33 from the overflow prevention port 32 of the overflow prevention pipe 33, and enters the inner cavity of the liquid return pipe 11 through the inner cavity of the overflow prevention pipe 33, and finally the overflowed nutrient solution is discharged through the inner cavity of the liquid return pipe 11. In order to ensure the reliability and sealing of the connection between the anti-overflow pipe 33 and the liquid return pipe 11, the anti-overflow pipe 33 and the liquid return pipe 11 are integrated into one structure in this embodiment.

[0054] Based on the third embodiment described above, at least two liquid return ports 111 are provided at the top of the liquid return pipe 11. When the liquid level of the nutrient solution in the receiving chamber 101 is higher than the height of the liquid return port 111 and lower than the height of the anti-overflow port 32, the nutrient solution enters the cavity of the liquid return pipe 11 from the liquid return port 111 and is discharged from the planting trough 10 through the liquid return pipe 11. When the liquid level of the nutrient solution is higher than the height of the anti-overflow port 32, the nutrient solution enters the anti-overflow pipe 33 from the anti-overflow port 32, then enters the liquid return pipe 11 through the anti-overflow pipe 33, and finally is discharged from the liquid return pipe 11. When the liquid level of the nutrient solution is lower than the height of the liquid return port 111, the nutrient solution continues to enter the receiving chamber 101 through the liquid supply hole 102, and the liquid level of the nutrient solution continues to rise.

[0055] Specifically, at least two liquid return ports 111 are spaced apart along the circumference of the liquid return pipe 11 and evenly arranged on the side wall of the liquid return pipe 11 to ensure that the nutrient solution evenly enters the liquid return pipe 11 along the circumference of the liquid return pipe 11 .

[0056] In some embodiments of the present invention, the supply speed of the nutrient solution pumped into the containing chamber 101 through the liquid supply hole 102 by the constant pressure water pump is greater than the return speed of the liquid return pipe 11 to ensure that the liquid level of the nutrient solution can continue to rise.

[0057] In some embodiments of the present invention, a plurality of rows of planting grooves 21 are provided on the planting board 20, and the utilization rate of the planting board 20 is improved by the plurality of rows of planting grooves 21, so as to provide a fixed structure for a plurality of strawberry plants. Two adjacent rows of planting grooves 21 are arranged in a staggered manner so that more planting grooves 21 can be accommodated on the planting board 20. The plurality of planting grooves 21 in each row are spaced and evenly arranged to ensure that the planting board 20 is more evenly stressed. The planting grooves 21 are distributed in a triangular positioning to ensure that the growth space and ventilation of the strawberry plants are more suitable.

[0058] In some embodiments of the present invention, the liquid supply hole 102 and the liquid return pipe 11 are arranged at both ends of the planting trough 10 along the length direction of the planting trough 10. The nutrient solution flows from one end of the receiving cavity 101 of the planting trough 10 to the other end, and then discharges from the planting trough 10, so that the nutrient solution flows the longest distance in the receiving cavity 101, ensuring that the nutrient solution can flow at all angles in the receiving cavity 101.

[0059] A second aspect of the present invention provides a hydroponic strawberry planting method, which is implemented according to the hydroponic strawberry planting device of any of the above embodiments, and the hydroponic strawberry planting method includes:

[0060] S1: Control the solenoid valve of the liquid supply hole to open, and then control the water pump to pump the nutrient solution into the receiving cavity of the planting tank through the liquid supply hole;

[0061] S2: When the liquid level in the containing chamber rises to the anti-overflow level 110, the solenoid valve of the liquid supply hole is controlled to close until the liquid level in the containing chamber drops to the intermittent level 120;

[0062] S3: Repeat the above liquid supply and discharge process multiple times;

[0063] The anti-overflow liquid level is located above the intermittent liquid level 120, and the intermittent liquid level 120 is located above the liquid supply hole.

[0064] According to the hydroponic strawberry planting method of the present invention, first, the electromagnetic valve of the liquid supply hole is opened by controlling the control pump to pump the nutrient solution into the receiving chamber of the planting trough through the liquid supply hole. When the liquid level in the receiving chamber rises to exceed the intermittent liquid level 120, the nutrient solution discharges part of the nutrient solution from the receiving chamber through the liquid return port. As the water pump continues to pump the nutrient solution into the receiving chamber, the liquid level continues to rise. When the liquid level exceeds the anti-overflow level 110, the electromagnetic valve of the liquid supply hole is closed. At the same time, the nutrient solution exceeding the anti-overflow level 110 is discharged from the receiving chamber. As the liquid level of the nutrient solution drops to the intermittent liquid level 120, the liquid level no longer drops and remains at this position. At this time, the root system of the strawberry plant is partially in the air, and the rest is in the nutrient solution. By repeating the above-mentioned liquid supply and drainage process at intervals for multiple times, the absorption and breathing ventilation of the nutrient solution by the strawberry root is improved, the bottom disease is reduced, and the strawberry yield is increased. Specifically, in summer, 4 to 6 cycles are circulated every day, and in winter, 2 to 4 cycles are circulated every day, which can also be set according to the strawberry seedling age.

[0065] It is to be understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present invention, but the present invention is not limited thereto. For those of ordinary skill in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
