Harvesting methods of breeding earthworms

Earthworms raised to a certain extent, in addition to a part for continued reproduction, the rest of the harvest used to raise centipedes, different breeding methods harvest methods are also different, roughly can be used in the following methods.

1) Light driving method This method is suitable for indoor breeding beds, breeding boxes and breeding ponds. Most of the earthworms in the breeding bed reach 400~600 mg, and under the condition that the density reaches 1.5~ 20,000 per square meter, a part can be harvested to avoid affecting the proliferation. The harvesting method can utilize the earthworms 'light-proof property, scrape the materials layer by layer with a scraping plate under the light, drive the earthworms to drill to the lower layer of the feeding bed, and gather into clusters. Then earthworms are placed on a large basket with an aperture of 5 mm, and the basket is placed under a collecting container. Under the illumination, earthworms automatically drill into the container under the sieve. Earthworms adhere to the surface of the dung particles and organic matter, residue on the screen. 2) Red light night catching method This method is suitable for the collection of earthworms raised in the field. It uses the habits of earthworms crawling to the ground at night to feed and move. At 3~4 o 'clock in the morning, carry a red light or a weak flashlight and collect them in the field. 3) Trap method This method is used in indoor breeding beds, and can also be used for harvesting earthworms in the field. Before harvesting, put a layer of food that earthworms like to eat on the surface of the old feed, such as rotten fruits, etc. After 2 to 3 days, earthworms gather in a large number of rotten fruits. At this time, quickly take out the earthworms in groups and clean up impurities through a sieve. In the field, the feed that earthworms like to eat can be selected, stacked near the feeding tank, and collected in the feed pile in the early morning of the next day. Also can dig a groove below 10 cm deep along the edge of the breeding pool or breeding pool, bury two ceramic vats about 30 cm deep at both ends of the groove, or dig two pits, some earthworms crawl along the groove at night, enter the ceramic vats or pits, and can be collected before dawn.
