Based on the above general structure principle, an exemplary structure of the device for raising seedlings by using sponge of the present embodiment is shown in fig. 1 in combination with fig. 2 and fig. 3, and mainly includes a seedling raising tray 3 and a sponge 5 flatly laid in the seedling raising tray 3, wherein a plurality of seedling raising grooves 501 are formed on the sponge 5; the device also comprises a seedling raising water tank 1, a plurality of water inlet holes 301 which are communicated with the bottom plate 30 of the seedling raising plate 3 and an isolation pad 4.
Wherein, the seedling raising water tank 1 is filled with seedling raising liquid, supports the placement of the seedling raising tray 3 and enables the bottom plate 30 of the seedling raising tray 3 to be immersed in the seedling raising liquid; the water inlet holes 301 are a plurality of through holes arranged on the bottom plate 30; the isolation pad 4 is disposed between the sponge body 5 and the bottom plate 30, and has a through hole 401 avoiding the position of the water inlet 301. Under the condition that the gravity of the sponge body 5 above the isolation pad 4 and the pressure of the seedling culture solution below the isolation pad 4 jointly act, the isolation pad 4 can enable the seedling culture solution to flow into the seedling culture tray 3 through the water inlet hole 301 and can form isolation of the flow.
As shown in fig. 4, the isolation pad 4 may be a thin plate having a surface closely attached to the upper surface of the base plate 30, and preferably, may be cut from a plastic plate. The isolation pad 4 is preferably sized and shaped to be capable of being fully paved on the upper surface of the bottom plate 30, and a plurality of through holes 401 are formed in the isolation pad 4 to allow the seedling raising solution to flow from the lower part of the isolation pad 4 to the upper part of the isolation pad 4 and further to be immersed in the sponge body 5, avoiding the positions corresponding to the water inlet holes 301.
In order to make the shape of the seedling raising water tank 1 more reasonable and facilitate processing and manufacturing, in the embodiment, the seedling raising water tank 1 is designed to be rectangular. Two relative basin lateral walls 102 of seedling culture basin 1 and connect overflow boundary wall 103 and the intake end boundary wall 104 between two basin lateral walls 102 enclose jointly and construct and form the lateral wall of seedling culture basin 1, can set up support or landing leg in the bottom plate below of seedling culture basin 1 to make the device arrange more rationally. The seedling raising tray 3 placed on the seedling raising water tub 1 is erected on the water tub side walls 102 on both sides by the seedling raising tray flanges 302 constructed on the side plates of the seedling raising tray 3. Set up seedling tray 3 on the basin lateral wall 102 of seedling tray 1 through its seedling tray turn-ups 302, form seedling tray 1 and to the bearing of seedling tray 3, make the placing and taking out of seedling tray 3 on seedling tray 1 more convenient and fast.
In order to improve the oxygen content of the seedling culture solution and to enable the seedling culture solution to form stable inflow pressure at the water inlet hole 301 of the seedling culture tray 3 immersed in the seedling culture solution, the seedling culture water tank 1 is provided with a circulating water pipe 201 for the seedling culture solution to flow in, and the circulating water pipe 201 and the overflow side wall 103 cooperate to enable the seedling culture solution which is in constant liquid level and circularly flows in the seedling culture water tank 1 to be maintained.

As shown in FIG. 5, an inflow pressure of the seedling raising liquid 6 is formed at the water inlet holes 301 due to the immersion of the seedling raising tray 3 in the seedling raising liquid 6, and the spacer 4 can form a block at the water inlet holes 301. When the sponge body 5 on the isolation pad 4 is immersed in the seedling culture solution 6 to a certain amount, the gravity of the sponge body 5 is increased, and a large downward pressure can be formed on the isolation pad 4, so that the isolation pad 4 is tightly attached to the upper surface of the bottom plate 30, the water inlet hole 301 is sealed, and the seedling culture solution 6 is prevented from further flowing in.
When the water in the sponge 5 is absorbed by the seeds or seedlings or evaporated to lower the water holding capacity of the sponge 5, the weight of the sponge 5 is reduced and the pressure applied to the mat 4 is reduced. At inlet opening 301 department, when the liquid 6 inflow pressure of growing seedlings of isolation pad 4 below was greater than the gravity that comes from isolation pad 4 itself and top cavernosum 5, the lower surface of isolation pad 4 can with the upper surface separation of bottom plate 30 to the liquid 6 of growing seedlings flows in through inlet opening 301 and educates seedling tray 3 in, and flows to the top of isolation pad 4 through dodging the through-hole 401 of opening inlet opening 301 position, and then permeates in the cavernosum 5.
It should be noted that the inflow pressure of the seedling raising liquid 6 at the water inlet 301 is related to the immersion depth of the seedling raising tray 3 in the seedling raising liquid 6, and by adjusting the depth, the amount of the sponge 5 immersed in the seedling raising liquid 6 can be changed, i.e., the water holding capacity of the sponge 5 can be adjusted. Aiming at the water preference degree of the seeds and the seedlings thereof, the water holding capacity of the sponge body 5 is adjusted and changed, so that the device has good applicability. For the above purpose, in the present embodiment, as shown in fig. 1, the seedling raising tray 3 may be disposed in a plurality of rows on the two side walls 102 of the water tank, and an adjusting mechanism may be disposed between the flange 302 of the seedling raising tray and the side wall 102 of the water tank. The height adjusting mechanism can adopt the forms of cushion blocks with different thicknesses, threaded holes, lead screws and the like, and is used as a common mechanism application method, and the details are not repeated. Thus, the adjusting mechanism can adjust the depth of the seedling-raising tray 3 immersed in the seedling-raising liquid 6.
In order to collect the seedling culture solution 6 overflowing from the overflow side wall 103 in time and facilitate the recycling of the seedling culture solution 6, a water receiving tank 101 can be arranged below the overflow side wall 103, and the seedling culture solution 6 overflowing through the overflow side wall 103 can flow into the water receiving tank 101. In addition, a circulating water pump 2 is arranged in the water receiving tank 101, and an outlet of the circulating water pump 2 is communicated with a circulating water pipe 201; the circulation flow of the seedling culture solution 6 in the seedling culture water tank 1 can be formed, thereby achieving the purposes of improving the oxygen content of the seedling culture solution 6 and keeping the liquid level.
In order to increase the seedling amount of the device and facilitate the observation of seedlings in the seedling process, as shown in fig. 3, the seedling raising grooves 501 are a plurality of grooves which are uniformly arranged on the sponge body 5 at intervals, and preferably, the seedling raising grooves 501 are densely and regularly arranged.
In addition, the upper part of the seedling raising groove 501 can be in a cylindrical shape so as not to contain the stems and leaves of the seedlings; and a through cross-shaped cutting seam can be constructed between the bottom of the seedling raising groove 501 and the bottom surface of the sponge body 5, so that the root of the seedling can grow and spread below and around the sponge body 5 through the cutting seam.
The device that adopts sponge to grow seedlings of above-mentioned embodiment, will grow seedlings 3 part and soak in liquid 6 of growing seedlings, make liquid 6 of growing seedlings flow in through the inlet opening 301 on the bottom plate 30 and supply cavernosum 5 to adsorb and hold water in growing seedlings dish 3, and through the setting of isolation pad 4 between cavernosum 5 and the bottom plate 30, when cavernosum 5 holds water and increases and make self gravity increase, isolation pad 4 can be because of pressure-bearing shutoff inlet opening 301, prevent the further inflow of liquid 6 of growing seedlings, thereby can prevent that cavernosum 5 from adsorbing and grow seedlings liquid 6 too much, in order to improve the gas permeability of sponge 5 of growing seedlings in-process.
