What are the farming techniques for earthworms?

1. Farming method: ten years of building, we have been insisting on open composting farming, I think, this method of low cost, is the best method of large-scale production of earthworm products, without any investment equipment, the use of all the vacant land, as long as the unfermented cow dung, horse dung, pig manure made into a height of 15-20 centimeters, width of 1-1.5 meters, the length of any length, into the earthworm species, covered with straw, shading and moisturizing, on the breeding.

2. We started feeding from a few square meters, until now, more than two hundred acres of land expansion with this method, the advantage is that the operation is convenient, eliminating the need for a series of heap fermentation work, the bait to maintain the nutrients are not lost to improve the growth rate of earthworms, easy to promote the use of rural areas. This method also has its drawbacks: once the bait heat, earthworms dead body, summer rainy days and heavy rain, the bed is not breathable, there is the phenomenon of escape.

3. The way to avoid this is to have new bait in each breeding bed. The bait to engage in the pile block, for earthworms to create good bottom-up conditions. The key to this method is to keep the bait at 60-70% moisture content, not too dry or too wet, otherwise the bait will heat up and cause death.

Earthworms like wet, afraid of drying: earthworms in the body of water content of about 80%, the requirements of the bait water content of 60% -80% (to hold the material in the hand, fingertips dripping water shall prevail), so the requirements of the culture of the bed water content of more than 60%, so that every day or every other day or 1-2 days, you must watering, water should not be too big, but to water through the lower layer of the material to catch up with the time of pouring for the winter at noon to pour, summer evening watering, spring and fall seasons, can be watered during the day. You can water during the day.

Like air, like static, loose bait is favorable to the growth of earthworms, we have many years of experience is to feed the bed before turning the support once (about 20 centimeters thick) to increase ventilation. This is very important, over the years, we found that the bottom of the bed soil, the number of earthworms is very small, but the bait is still there, mainly because of the lack of air, which is unfavorable to the growth of earthworms.
