Earthworm summer farming requires good cooling work

Building a shed for shade: Through practical comparison, a curtain made of wheat straw or rice straw on the shed gives better shade than other methods (such as growing climbing plants, placing rapeseed baskets, etc.). Build the shed low in the south and high in the north. Hang the straw curtain first from the center of the shed roof. Cover the worm bed with a straw curtain, preferably with water hyacinth, alligator weed, green grass, etc. Tests showed that when the air temperature was 34°C, on a worm bed covered with a straw curtain inside the shed, the temperature 6 cm below the surface of the worm bed was 30°C; when covered with 40 cm to 50 cm of alligator weed, the temperature was 28°C; with no shed and only an old mat, the temperature was 35°C. Therefore, after building the shed, covering the worm bed with a straw curtain, especially covering it with water hyacinth or alligator weed for cooling, not only makes the earthworms grow faster but also greatly increases egg production.

Covering the worm bed with grass: As the temperature gradually rises, a straw curtain must be placed over the shaded worm bed, preferably covered with water hyacinth, alligator weed, green grass, etc. Watering for cooling: During high-temperature periods, water once every afternoon to help the earthworms crawl to the surface of the worm bed at night to feed in a moist environment. If conditions permit, watering twice, morning and evening, has an even better effect. Never use paddy field water that has been heated very hot by the sun or seriously polluted industrial wastewater. Using the above comprehensive cooling measures during high-temperature periods, combined with annual greening, can reduce the worm bed temperature to within 30°C, avoiding earthworms entering high-temperature dormancy and affecting yield. In short, raising earthworms should be based on local climate conditions, adopting suitable warming or cooling measures so that the worm bed temperature throughout the year is controlled within the range most suitable for earthworm growth and reproduction.
