The production of pleated oysters with seedlings and the setting of seedlings

Shell string production should be selected larger pleated oyster bottom shell, hole in the top of the shell, with a 45-60 monofilament polyethylene into a small rope, wear knots to the shell string, wear a knot note when the knot slip, make two The shell is flat and expanded with Miaokong and it varies depending on the cultivation method. Shelf type farming is generally 1.6-1.8m in length, and the shell distance is 8-9cm; the floating bench is 3m long and shell distance 10-12 centimeters, 20 centimeters at the two ends of the rope are used as tethers. Each 5-10 string has two ends of the rope tied together to form a bundle, avoiding entanglement. The total length of the shell string is 2000 mu for 1 mu.
Seedlings are used to place shells to collect seedlings. In order to set the seedling rack, it is necessary to first select the area where the seedlings are to be planted. Generally, it is appropriate to select a tide area with a dew-drying time of 1.5-2 hours in the low tide area, or a sea area with a relatively stable seedling volume after long-term seedling verification. Picking frame structure: using bamboo or wood for the frame bar, erected into a rectangular rack, width 1-1.2 meters, depending on the number of rotating shell strings long-term coexistence of the terrain of the sea, the height control at about 50 cm from the ground. It can also be drawn into a rope frame with a polyethylene rope. The erection of picking frames should be solid and safe, and the vertical wind direction should be set to prevent cross-winds from falling. When the shell string is placed on the shelf and the seedlings are picked, the string is firmly sealed with a small string to prevent storms from escaping.
