As shown in FIG. 11, the water circulation flow chart of the present invention is that the first production is realized by externally adding tap water to a constant temperature water tower, the constant temperature water tower maintains the water temperature at 25-30 ℃, the water flow enters into a water inlet pipe through a water supply system, warm water is sprayed onto sprouting vegetables through a spray head, a small amount of loss is generated in the water flow spraying process, a part of water is used for maintaining the indoor humidity constant, a part of water is lost along with ventilation, the water flow enters into a seedling raising tray and enters into a base plate 1 of the seedling raising tray through small holes 7 on a partition plate 2, the water flow discontinuously washes the roots of water spinach seedlings, a part of water is stored in the base plate 1, the part of water is discontinuously updated, a large amount of germs cannot be bred in the water in the seedling raising tray, the other part of water overflows onto a layer plate 11 through holes 4 on the base plate 1, and the water on the layer plate 11 is collected into a branch drainage pipe 26 and a main drainage pipe 25 through a vertical water collection groove 20 and a horizontal water collection, the collected wastewater is pumped into a water treatment system through a water pumping pipe for treatment, and because a large amount of solids do not exist except a small amount of seed coats in the wastewater and the wastewater has good water quality, the wastewater can be recycled only through disinfection and simple filtration, and the water quality of the water treatment system can be fed into a constant-temperature water tower after reaching the standard of tap water, a small amount of tap water needs to be intermittently replenished in order to complete the recycling due to the loss of water in the production process, so that the water level of the constant-temperature water tower is kept constant;

as shown in fig. 12, in order to make the temperature of the air blown into the seedling raising workshop by the blower device proper and prevent the cold air from directly blowing to the sprouts to cause slow growth and even freezing injury of the sprouts, the heat exchanger is arranged between the blower device and the air inlet, the heat source is warm water in the constant temperature water tower, the air flowing through the heat exchanger is simply preheated by forced circulation, and the warm water in the constant temperature water tower is stirred by forced circulation, so that the situation that the temperature of the water measured at the temperature measuring point is too low, the constant temperature water tower is continuously heated, and production accidents are caused is prevented; the preheated air enters the seedling raising workshop through the air inlet to replace the air in the seedling raising workshop, is discharged through the air outlet to take away carbon dioxide and the like generated by the growth of the bud seedlings, maintains the content of oxygen in the air in the seedling raising workshop stable, adjusts the humidity of the seedling raising workshop through the blast volume and maintains the humidity constant at 70-80%;

through the above steps, can realize water spinach sprouting vegetable production process green, do not have the interpolation, and can ripe about 13 days, production cycle is short, growth process management is simple, degree of automation is high, but the large-scale production, and do not receive natural condition's restriction, realize the anniversary supply, can produce according to the order, set up the workshop of growing seedlings in different growth stages respectively, can also be through removing the support, three-dimensional planting, incessant output sprouting vegetable, sprouting vegetable growth cycle on same support is the same promptly, there is the sprouting vegetable of different cycles in the same workshop of growing seedlings, can realize the incessant supply to big customer, the input-output ratio is high.

Example 2

Example 2 is the same as example 1 except for the following parts:

the distance between the laminated plates is 0.5m, and an included angle of 30 degrees is formed between the laminated plate 11 and the horizontal plane;

the back surface of the layer plate 11 is not provided with a fluorescent lamp;

the base plate and the top cover are made of lightproof food-grade safe plastics, and the partition plate is made of food-grade hard PVC;

the seedling tray that educates of embodiment 2 is applicable to the sprouting vegetable that needs whole shading growth such as soybean sprouts, and this kind of sprouting vegetable sees the light after, can produce the chlorophyll, and the sprouting can afforest, and produces a large amount of fibre, and the taste that leads to the sprouting vegetable is not good, only need keep temperature and humidity, intermittent type water spray, ventilation in the growth process can, the chassis can satisfy the requirement of growth and packing with the material of top cap for the safe plastics of opaque food level.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification or equivalent substitution made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
