When the temperature rises, it becomes highly favorable for earthworms to grow and reproduce. However, during the intense summer heat, it is essential to implement cooling measures to keep the trampoline (bed) temperature below 30°C, which is crucial for maintaining high productivity during the summer season. Here are some effective methods:
1. **Shade Covering**: In practice, using curtains made from wheat stalks and rice straw proves more effective than other methods like climbing plants or rapeseed pods. The shed should be constructed with a southern orientation and a lower northern side. A straw curtain is hung from the center of the shed, and a grass curtain is placed over the bed. It is best to cover the area with water hyacinth, water peanuts, and grass. Testing has shown that when the outside temperature reaches 34°C, the temperature 6 cm below the surface of the trampoline is 30°C. With a 40–50 cm layer of water peanuts, the temperature drops to 28°C, while an old mat without a shed keeps the temperature at 35°C. Therefore, after setting up the structure, it’s important to cover the trampoline with straw curtains, especially using water hyacinth and water peanuts for better cooling. This not only speeds up earthworm growth but also significantly increases their reproductive capacity.
2. **Trampoline Grass**: As temperatures rise, it's necessary to cover shaded trampolines with straw curtains. Using water hyacinth, water peanuts, and green grass is recommended for optimal results.
3. **Watering for Cooling**: During hot periods, watering once daily in the afternoon helps create a humid environment at night, encouraging earthworms to climb to the surface for feeding. If possible, watering twice a day—either earlier or later—is even better. Avoid using very hot paddy field water or heavily polluted industrial wastewater. Combining these cooling strategies with annual greening efforts can bring the trampoline temperature below 30°C, preventing high-temperature dormancy that could reduce yields.
In summary, earthworm conservation must be tailored to local climate conditions, with appropriate measures taken to either increase or decrease temperature. Keeping the trampoline within the ideal temperature range for growth and reproduction is key to long-term success.
