Shed shading: In practice, straw shades made of wheat stalks and rice straw are better than other methods (such as climbing plants, and rapeseed pods). The shed is built to the south and low to the north, and the straw curtain is hung from the center of the shed, and the grass curtain is covered on the gong bed. It is best to cover the water hyacinth, water peanut and grass. After testing, when the temperature is 34°C, the temperature of the 6 cm below the surface of the boring machine is 30°C; the cover is 40 cm to 50 cm thick and the temperature is 28°C; The mat temperature is 35°C. Therefore, after the scaffolding, the trampoline is covered with straw curtains, and in particular, the water hyacinths and the water peanuts are cooled. Not only does the earthworm grow fast, but also the spawning capacity greatly increases.
Muddy Grass: When the temperature is getting higher, straw curtains must be covered on the shady trampoline. It is best to cover water hyacinths, water peanuts, and green grass.
Watering and Cooling: The high temperature period must be watered once a day in the afternoon to make it easier to crawl on the surface of the trampoline at night in a humid environment. Do not use very hot paddy field water or seriously polluted industrial wastewater. In the high-temperature period, the comprehensive cooling measures mentioned above, combined with the annual greening, can reduce the temperature of the trampoline to less than 30°C, so as to avoid the high temperature dormancy from affecting the yield.
In short, the conservation of earthworms should be based on the local climatic conditions, take appropriate measures to increase the temperature or cooling, making the trampoline annual temperature control in the most suitable range of growth and reproduction.
