The invention relates to the field of aquaculture, in particular to a device and method for three-dimensional seedling culture and bottom sowing proliferation of buried shellfish, the device comprises a culture frame and a culture disc, the culture disc comprises side plates, placing strips, seedling attaching devices and connectors, the side plates define a rectangular frame, the top and the bottom of the rectangular frame are both open, and the placing strips are arranged on the rectangular frame. A plurality of water permeable holes are formed in the side plates, the shelving strips are arranged on the outer sides of the side plates in parallel, the seedling attachment device is supported and blocked at an opening in the bottom of the rectangular frame, the seedling attachment device is connected with the opening in the bottom through the connector, and the breeding frame comprises a three-dimensional frame and shelving strip frames. The placing strip frames are arranged in the three-dimensional frame in parallel, and the placing strips are placed on the placing strip frames. By using the device provided by the invention, the density of the fries during attachment can be adjusted, so that the density of the attached fries tends to be reasonable, and the density suitable for the growth of the fries is obtained.

The present application relates to the field of aquaculture, and particularly relates to a device and method for vertical seedling and bottom sowing and propagation of sessile shellfishes, comprising a culture frame and a culture tray, wherein the culture tray comprises a side plate, a shelf, a seedling attachment device and a connector, the side plate forms a rectangular frame, the top and bottom of the rectangular frame are open, a plurality of water-permeable holes are arranged on the side plate, the shelf is arranged in parallel on the outer side of the side plate, the seedling attachment device is arranged to block the opening at the bottom of the rectangular frame, the seedling attachment device is connected to the opening at the bottom through the connector, the culture frame comprises a three-dimensional frame and a shelf frame, the shelf frame is arranged in parallel inside the three-dimensional frame, and the shelf is arranged on the shelf frame. By using the device, the density of the seedlings during attachment can be adjusted, the density of the seedlings is made to be reasonable, and the suitable density for the growth of the seedlings is obtained.

The invention discloses application of aconitic acid in inhibition of browning of fruits and / or vegetables and inhibition of microorganisms. The use method of the aconitic acid is simple, and the aconitic acid only needs to be added into fruit and vegetable pulp or prepared into an aconitic acid aqueous solution to be used for soaking fresh-cut fruits and vegetables which are cleaned, disinfected, peeled and cut. Experiments prove that aconitic acid can effectively inhibit browning of apple, potato and snow pear slurry, fresh-cut apple slices and shredded potatoes, maintain the original color and flavor of the apple, potato and snow pear slurry, fresh-cut apple slices and shredded potatoes, maintain the original flavor of fresh-cut cucumbers and inhibit the total number of bacterial colonies of fresh-cut fruits and vegetables; the medicine has the advantages of safe use and no toxic or side effect. The treatment method for inhibiting browning and microorganisms of the fresh-cut fruits and vegetables by using aconitic acid provided by the invention is simple, easy to operate and popularize, low in cost and suitable for large-scale production and use.
