Second, the method of collecting earthworms

1, irrigation capture method

Earthworms are afraid of stagnant water. Generally speaking, they can be caught after they are dug out of holes by irrigation, or they can be caught in rice fields during spring ploughing.

2, accumulation and capture method

It is necessary to pile fermented feed in fields, vegetable gardens and other places, mainly for attracting earthworms. The height of the pile is 30-40 cm, the width is 40-50 cm, and the length is not limited. Earthworms usually gather after 3-5 days. If 50% soil is added as feed, the trapping effect will be better.

3. Excavation method

Earthworms can be caught by digging nails and iron rakes. The method is simple, but the effect is not very good. This method is suitable for small-scale agriculture.

4, chemical capture method

You can use 0.55% formaldehyde solution (13.7L/m2) or 15% potassium permanganate solution (7L/m2) to spray at the place where the earthworm is collected, and the earthworm will soon climb to the ground, so it is more convenient to collect at this time.

Third, the distribution range of earthworms

Earthworms exist in most ecosystems in the world, but the ocean is the natural barrier of earthworms, and it is also rare in desert areas and snow-covered areas all year round. Earthworms are mainly distributed in the surface layer of soil, where organic matter is rich. General soil structure, pH, aeration and water content are all factors that limit the distribution and quantity of earthworms.
