feed field culture method: open a groove with a width of 15 cm in the feed field and put earthworms in it. Vegetable garden cultivation method: after the vegetable seedlings are unearthed, the earthworm is put into the soil for cultivation. Orchard culture method: pile up cow dung piles under fruit trees as a breeding bed for earthworms. Mulberry garden cultivation method: dig a groove in mulberry garden and put earthworm into it for cultivation.
How to breed earthworms
1. Breeding in feed field
Choose the soil where cyan feed is planted all the year round to breed earthworms, open a trench with a width of 15 cm and a depth of 2 cm on the land where feed is planted, add decomposed organic fertilizers, such as dead leaves, weeds, cattle and sheep manure, etc. into the trench, then fill in about 1 cm of soil, put earthworms in it, and water appropriately to keep the soil water content at 3%.
2. Vegetable garden cultivation method
Vegetable garden soil is fertile and most suitable for earthworm growth and reproduction. Apply organic fertilizer or decomposed vegetable leaves and cow manure to the soil for earthworm cultivation, with an amount of 75-1 kg per mu. After the vegetable seedlings are unearthed, put the earthworm into the soil for cultivation, and reduce the use of nitrogen fertilizer and pesticides.
3. Orchard culture method
Culturing earthworms in orchards makes rational use of land, and can also promote the increase of fruit tree yield. Under the fruit trees, a pile of decomposed pigs and cow dung, which is 1.5-2 meters wide and .4 meters high, is piled as a breeding bed for earthworms, and the breeding bed is covered with straw to keep the humidity of the breeding bed at 6%-7%.
4. Mulberry orchard breeding method
To raise earthworms in mulberry orchards, it is necessary to choose mulberry orchards with relatively flat terrain and strong drainage capacity, dig a groove with a width of 4 cm and a depth of 2-25 cm along the mulberry trees, then add decomposed farmyard manure, cover with soil with a thickness of 1-15 cm, and put in earthworms for breeding.
