Background

The tide seedbed which is often used in the current agricultural production can only singly carry out plug seedling and potted plant production, or can only singly carry out hydroponic vegetable production, and the use scene is limited.

The traditional ABS tide seedbed has poor heat preservation effect, can only be used in a greenhouse with a covering material capable of absorbing ultraviolet rays, has the advantages that residues such as turf are easy to remain in a water flow channel of the seedbed, the cleaning is difficult, pipelines are easy to block, and the propagation and the installation of plant diseases and insect pests are complicated; difficult to disassemble; the water leakage is easy to occur in the subsequent use process.

The traditional water planting seedbed has the application prospect limited to water planting crops, and can not cultivate potted plants and carry out seedling raising.

The tide seedbeds conventionally used in production mainly comprise an ABS tide type irrigation seedbed and a traditional water planting seedbed, and the method is as follows:

ABS tide type irrigation seedbed:

1.1 mode of operation:

the cultivation groove in the seedbed is made of ABS material, a plurality of criss-cross water flow channels are arranged at the lower part of the groove, water flows out from the water inlet during irrigation, and is accumulated to a proper height (called as "tide rise") in the cultivation groove and is retained for a certain time, the plants absorb water from the bottom by utilizing the siphon principle, and the water is returned from the water return port after irrigation is completed (called as "tide fall").

1.2 the seedbed has the main problems:

1) The ABS material is easy to degrade under the action of ultraviolet light, so that the service life is shortened, and the seedbed is required to be used in a space with ultraviolet irradiation resistance, namely, the seedbed can only be used in a greenhouse with a covering material capable of absorbing ultraviolet light, otherwise, the service life is reduced, and the limitation of space use is caused;

2) The thickness of the wall of the cultivation groove of the ABS seedbed is only 3mm, the heat insulation effect is poor, the heat dissipation speed is high, and when the temperature of the cultivation small environment is raised by combining a method of erecting a small arch shed on the seedbed and irrigating with high-temperature irrigation water in winter and spring, the ideal heating effect cannot be achieved due to the characteristics of the material, so that the heat insulation effect of the seedbed is poor;

3) Criss-cross water flow channels arranged at the bottom of the cultivation groove are narrow, residues such as matrixes, fallen leaves and petals are easy to accumulate in the channels, cleaning is difficult, and the residues are easy to rot and grow plant diseases and insect pests after being soaked in irrigation water for a long time;

4) When the seedbed is spliced, the cultivation groove of one seedbed is formed by splicing a plurality of sub-master plates, the sub-master plates are required to be adhered by glue to prevent water leakage, and the process of glue adhesion is very labor-consuming, tedious in installation and time-consuming; if part of the positions are damaged after bonding or the positions of the seedbed need to be replaced, the disassembly is difficult, the glue adhesion parts are aged after long-time use, water leakage is easy, and the repair is difficult;

5) The liquid inlet pipeline and the liquid return pipeline on the ABS seedbed share one connecting piece for liquid supply and liquid return, the number of filter meshes arranged on the connecting piece is low, impurities such as matrixes and the like are easily brought into the pipeline, and the smoothness and cleanliness of the liquid return are affected;

6) The seedbed will not return liquid when supplying liquid, and the liquid will not return until the liquid supply is stopped. The liquid level of the liquid supply is controlled by controlling the water supply time, the relation between the liquid supply time and the liquid level is required to be carefully calculated before use, the liquid supply time is required to be newly calculated when the liquid level of the liquid supply is regulated each time, the liquid level cannot be kept constant for long-time irrigation, and if the liquid supply time is set too long or the liquid supply is forgotten to be closed during manual operation, water flow can overflow the seedbed;

7) The seedbed is not provided with a matched water planting device (a field planting plate and the like), water exists only in the time of tidal irrigation, the requirement that the seedbed is required to always keep a certain liquid level for water planting crops cannot be met, the production of plug seedling and potted plants can only be carried out singly, and the use scene is limited.

Traditional water planting seedbed:

2.1 mode of operation:

such seedbeds are generally divided into two modes, deep-liquid hydroponics and nutrient film hydroponics:

2.1.1 deep liquid hydroponic modes: the whole seedbed is kept in a horizontal state, irrigation water flows out from a water inlet at the front end of the seedbed during irrigation, and overflows from an overflow port at the other end of the seedbed after accumulating to a certain height in a cultivation groove, and the liquid level is always kept below the overflow port after the irrigation is finished;

2.1.2 nutrient solution film hydroponic modes: the whole seedbed keeps a certain proportion of slope, water enters from a water inlet at the relatively high end of the seedbed during irrigation, and water flows to the relatively low end of the seedbed under the action of gravity and flows into a liquid return pipeline;

2.2 the seedbed has the main problems:

1) In order to enable part of root systems of hydroponic crops to be soaked in irrigation water all the time, the seedbed is arranged to maintain a certain liquid level of water depth in a cultivation groove all the time, the design ensures that the seedbed is always in a water state and cannot be completely drained, the requirements that potted crops or plug seedlings cannot have ponding except the irrigation time on the seedbed cannot be met, and the seedling bed cannot be used for plug seedling or potted plant cultivation;

2) Nutrient solution film hydroponic seedbed in order to keep the irrigation water shallow flowing, from one end of the seedbed to the other end, the seedbed will set 1: (75-100) a drop, which is designed such that the seedbed cannot accumulate a level of height to provide sufficient and uniform moisture to the trays and potted plants;

3) Simultaneously, the two planting modes all require a user to walk back and forth in the seedbed to perform fixed planting, harvesting and other works, so that the labor efficiency of staff is reduced;

4) The use scene of the traditional water planting seedbed is limited to water planting crops due to the factors, and the traditional water planting seedbed cannot be used for the production of potted plants and plug seedlings; the automatic planting and harvesting work cannot be performed by combining the automatic planting and harvesting equipment, and the production efficiency is seriously lowered.

(1) Realizing the heat preservation function of the seedbed:

the cultivation groove and the field planting plate 500 which are made of EPS heat preservation materials, and a soil engineering film which is arranged as a waterproof film are used for realizing the heat preservation of the cultivation groove of the seedbed, and can prevent condensed water from occurring on the frame of the seedbed, and a small arch shed can be erected on the upper part of each seedbed in cold winter, and the cultivation film and the non-woven fabric are matched for multiple heat preservation.

(2) Simple and convenient structural design of seedbed installation and dismantlement:

the cultivation groove is not required to be connected, only needs to be placed on the seedbed bottom support in sequence and tightly, a waterproof film is paved on the cultivation groove, the film is clamped between the seedbed frame and the plastic buckle, all the components are also required to be disassembled in sequence during disassembly, and the operation is very simple and convenient and cannot cause the damage of the components.

(3) Prolonging the service life and reducing the limit to the field:

the ultraviolet-resistant waterproof membrane can resist the adverse effect of ultraviolet rays on the seedbed, the seedbed can be used in a protected area with ultraviolet rays, and the service life of the seedbed is not affected while the seedbed is more beneficial to the growth of cultivated crops; because the waterproof membrane 700 is fixed with the cultivation groove by using the buckle, after the waterproof membrane is aged or damaged, the buckle is only required to be loosened, the new waterproof membrane 700 is replaced, no influence is caused on other parts of the seedbed, and the service life of the seedbed is greatly prolonged.

(4) The height of the irrigation liquid level is adjustable, the liquid supply time is not influenced by the height of the liquid level, and the problem of seedbed overflow is solved:

the function is realized through the cooperative operation of the water falling groove 900, the water falling device 1000 and the overflow port 1100, after the water falling device is arranged on the seedbed, liquid return can be automatically carried out when liquid supply reaches the high liquid level of the water falling device, and the liquid supply time is not required to be tested for changing the liquid level.

The specific method for water level adjustment is as follows: the overflow port 1100 is set to the highest water level, the water level at which the water falling device 1000 starts to operate is set to the high water level, and the water level at which the operation is stopped is set to the low water level:

when the tidal irrigation of the hydroponic crops is carried out, a ball valve 1020 of the water falling device 1000 is required to be opened, and the position of the water falling device 1000 is controlled by rotating the top cover of the water falling device 1000, so that a specific liquid level interval during the irrigation in a seedbed is controlled;

after irrigation is started, irrigation water uniformly flows into the cultivation groove from the water distributor at the water inlet, when the liquid level exceeds the top cover of the water falling device and reaches a high water level, the water falling device 1000 is started to perform quick liquid return, and when the liquid level is reduced to the lower part of the top cover and reaches a low water level, the water falling device 1000 stops working and stops liquid return;

through the working principle, the water falling device can keep the irrigation liquid level in a fixed range, so that the root system can fully absorb moisture and nutrients and quickly update the air in the seedbed, thereby being beneficial to root system growth.

When the plug seedling and the potted plant cultivation are carried out, the water on the seedling bed needs to be completely drained after the irrigation is finished, and no ponding exists; the aim of realizing the effect is realized by only adjusting the height of the low water level to be lower than the upper surface of the EPS cultivation bed and matching with the water flow channels on two sides of the cultivation groove; when the liquid returns, the water in the middle part flows to the water flow channels on the two sides due to gravity, and then flows back to the water falling groove 900 from the two sides, so that no accumulated water on the bed surface is realized;

when the highest water level is required, the ball valve 1020 of the water falling device 1000 is closed, so that water cannot flow out of the water falling device but flows out of the overflow port 1100.

The irrigation water can be kept between constant liquid level differences only by adjusting the height of the water falling device before liquid supply, and the relation between the liquid supply time and the liquid level is not required to be calculated; the additionally arranged overflow port 1100 can also ensure that the seedbed can not overflow irrigation water when the water falling device 1000 fails and water can not return; even in a group of seedbeds with uniform liquid supply, the height of the water falling device 1000 can be adjusted to meet the liquid level requirements of different crops, so that the seedbed is flexible and changeable, and the application range is wide.

(5) Switching of usage scenarios:

through the adjustment of liquid level and the use of field planting board 500, can switch among the use scene such as deep-flow hydroponic crop, irrigation water film hydroponic crop (special arc cultivation groove setting can reach the standard of irrigation water film cultivation under the condition that the seedbed does not have the slope), cultivated plant production, morning and evening tides plug seedling, can in time adjust the use scene according to the change of market quotation, reaches maximum economic benefits.

(6) The seedbed is simple to clean and is not easy to accumulate impurities:

the cultivation groove and the waterproof membrane surface are smooth curved surfaces, so that the quantity of water flow channels is reduced while water flow is smooth and free of ponding, less impurities are accumulated and easy to clean, after each cultivation operation is finished, running water can be used for flushing, and surface impurities are easy to clean.

(7) The residue is difficult to flow into the liquid return pipeline:

the impurities in the return liquid are filtered by placing a piece of filter cotton with the same width as the seedbed and the same height as the overflow port 1100 in front of the water falling groove 900, so that the impurities cannot flow into the return liquid pipeline.

(8) The fixed-point operation mode can be realized when the water planting crops are in water planting, and the fixed-point operation mode is organically combined with the automatic equipment:

two buckles are arranged in the middle of each field planting plate 500, and the special buckle parts are used for connection, so that all field planting plates 500 on the whole seedbed are connected into a whole: when fixed-point transplanting or harvesting is needed, the irrigation liquid level needs to be the highest, and the irrigation water can flow back to the highest liquid level through the overflow port by closing the ball valve 1020 at the lower part of the water falling device 1000.

Because EPS material's characteristic, when the liquid level reached the highest water level has exceeded the height of field planting board, can make the field planting board float on the irrigation surface of water, resistance significantly reduces, because the board has even as an organic whole between the board, can drive all field planting boards on the whole seedbed through pushing/pulling field planting board of seedbed one end this moment, realizes fixed point operation.

The tidal type heat preservation seedbed has the beneficial effects that:

by using the EPS cultivation tank, the ultraviolet-proof one-step one-film waterproof film, the special seedbed frame and the plastic buckle structure, compared with the seedbed used at present, the novel seedbed has the advantages of simplifying the mounting and dismounting steps, prolonging the service life, expanding the space adaptability and increasing the heat preservation performance;

by using a unique cultivation groove water flow guiding design, a large number of water flow channels are reduced under the condition that water flow is smooth and no water accumulation exists in the seedbed, so that the possibility of impurities accumulated in the channels is reduced, and the seedbed is cleaned conveniently and thoroughly;

the liquid supply and the liquid return are arranged at two ends of the seedbed, so that irrigation water uniformly flows through the seedbed, the small environment in the seedbed is kept uniform, and the situation that crops grow unevenly due to large rhizosphere environment difference is avoided;

the filter cotton is arranged at the front end of the seedling bed water outlet to prevent impurities from flowing into the water outlet, so that the water flow is smooth and the cleaning of returned liquid is ensured;

through the cooperation among the water falling groove 900, the water falling device 1000 and the overflow port 1100, the liquid level of the seedbed can float among the highest water level 930 of the overflow port, the high water level 920 of the water falling device and the low water level 910 of the water falling device, only the height of the water falling device 1000 is required to be adjusted, the liquid supply time is not required to be measured and calculated, the liquid supply time length can be set according to the specific use scene and the requirements of variety characteristics, no upper limit exists, and the risk of overflow of the seedbed is avoided;

through the adjustment of the liquid level and the use of the field planting plate 500, the switching of various use scenes such as plug seedling, potted plant production, water planting crop cultivation and the like is realized, and the limitation that the traditional seedbed can only meet one of the limitations is solved. The production direction can be timely adjusted by a user according to market changes, so that the income is maximized;

through the adjustment of the liquid level and the connection of the field planting plate 500, the fixed-point harvesting/transplanting function is realized, the land utilization area is increased, the labor intensity of workers is reduced, and preconditions are provided for the organic combination with the automation equipment.
