Description

Technical Field

[0001] The present invention relates to the technical field of seedling cultivation, in particular to a device for generating a soilless melon seedling cultivation matrix and a seedling cultivation method. Background Art

[0002] At present, when conducting relevant experiments on soilless seedling cultivation of melon agricultural products, enzyme fertilizers are usually used as the source of nursery growth. However, research has shown that the enzymes added to agricultural enzyme preparations and enzyme fertilizers are absorbed by melons and transmitted to the human body, and their safety has not been proven. At the same time, the types of synthetic enzymes are limited and their functions are not comprehensive. Although they can promote the rapid growth of melon agricultural products, they will cause the taste of melon agricultural products to fade and lose their natural high-quality flavor.

[0003] Green manure is a clean organic fertilizer source, which is processed into green agricultural materials containing a large amount of natural enzymes and full nutritional value. However, in the laboratory environment, the production of green manure mainly depends on Figure 1 The reactor shown includes a base 1, a column 2, a cover opening mechanism 3, a kettle body 4 and a kettle cover 5, wherein the kettle body 4 is installed on the base 1, and the kettle cover 5 is connected to the column 2 which can be adjusted up and down by the cover opening mechanism 3 to realize anaerobic fermentation of fresh green plant materials.

[0004] However, during the green manure fermentation process, material compression and refining are also required. This reactor alone cannot complete all the steps. This means that the intermediate products from the reactor need to be transferred to other equipment for further reaction.

[0047] Figure 2 Schematic diagram of a device for generating a melon soilless seedling matrix according to an embodiment of the present invention. Figure 2 As shown, and reference Figure 3 and Figure 4The embodiment of the present invention provides a generating device, comprising a reactor 100, a central tube 200, a pressing plate 300, a lower grinding plate 400, an upper grinding plate 500 and a driving device 600, wherein: the reactor 100 comprises a reactor body 110 with an upper opening and a reactor cover 120 provided on the opening, the reactor cover 120 being reciprocatingly arranged up and down relative to the reactor body 110, and a discharge port 130 being formed at the bottom of the reactor body 110; the central tube 200 is coaxially fixed to the reactor cover 120 and its lower end extends into the reactor body 110; the pressing plate 300 is rotatably sleeved on the lower end of the central tube 200, and is arranged between the pressing plate 300 and the central tube 200. An electromagnetic clutch (not shown in the figure) is arranged between the lower grinding disc 400 and the pressure plate 300; the lower grinding disc 400 is rotatably sleeved on the central tube 200 and abuts against the top of the pressure plate 300, and a grinding head mechanism 700 for controlling the extension and retraction of the grinding head at the bottom of the pressure plate 300 and a locking mechanism 800 for locking the lower grinding disc 400 and the pressure plate 300 are arranged between the lower grinding disc 400 and the pressure plate 300; the upper grinding disc 500 is rotatably sleeved on the central tube 200 and is arranged above the lower grinding disc 400; the driving device 600 is arranged on the kettle cover 120, and connects the lower grinding disc 400 and the upper grinding disc 500 in relatively reverse transmission.

[0048] During use, the material and the awakened anaerobic composite bacterial solution are loaded into the kettle chamber through the upper opening of the kettle body 110. The lower grinding disc 400 is then rotated to expose the grinding head from the bottom of the pressure plate 300. The pressure plate 300 is then rotated to knead and crush the material. After the material has been crushed for a period of time, the lower grinding disc 400 is rotated counterclockwise, causing the grinding head to retract and pressing the pressure plate 300 downward to compress and ferment the material. After compression and fermentation, the lower grinding disc 400 is rotated clockwise again, and the pressure plate 300 is rotated clockwise and the upper pressure plate 300 is rotated counterclockwise. This allows the high-fiber material to be refined at a high concentration below the pressure plate 300, while the low-fiber material is refined at a medium concentration between the upper and lower grinding discs 500 and 400. The bacterial solution for fermentation is injected into the lumen of the central tube 200.
