First, the method of raising earthworms
1. Feed block culture method. A glass box about 30 cm square is used as a feeding box. The bottom of the box is covered with 10 cm soil, and the soil is covered with 5 cm thick straw soaked in water. Put 200 young earthworms in the box and keep the temperature at 25℃. 10 block feed with a diameter of 1 ~ 3 cm was put into the box respectively. This method saves labor and materials and is convenient for separating larvae.
2. Box culture method. Make a culture tank about 4 square meters. There is a partition in the water tank. The partition can be inserted into the culture box. There is a drain hole at the bottom of the box. Feed is spread in the box and earthworms are put in it. There are sprinklers and vents in the water tank. Earthworms are cultivated in this way, and a culture pond of about 3.3 square meters can cultivate 6,543,800+worms.
3. Plastic greenhouse cultivation method. Suitable for outdoor farming in winter. The shed is 2.4m high and 15 ~ 20m long. The plastic shed is arched, and vegetables can also be grown on the ground in the shed. Earthworms cultured in plastic greenhouses can not only survive the winter safely, but also breed in large numbers.
4. Soil hotbed cultivation method. This method can be used for winter breeding. The slope of the soil hotbed faces south. Spread 20 cm thick horse manure 4 cm below the topsoil in the bed and stamp it with your feet to increase the temperature. Cover the bed with glass or double blue plastic film to absorb sunlight and keep warm. When staying overnight, put a straw curtain on the bed.
5. Mulberry culture method. Mulberry garden row spacing is generally around 1.3 meters, and a ditch with a width of 35 cm and a depth of 1.5 ~ 20 cm is opened in the middle. The bait is spread on the bottom, covered with soil, watered and kept moist, and earthworm seeds are added. The advantage of this method is that it can not only raise earthworms, but also increase the yield of mulberry leaves, which is more suitable for raising green earthworms.
6. Green feed field, corn field or vegetable field cultivation method. This method is also suitable for raising green earthworms. The method is to dig a drainage ditch around the ground, plant crops in the field according to the row spacing of 35 cm, open a ditch with the width of 15 ~ 20 cm and the depth of 15 ~ 20 cm in the center of the row spacing, spread bait, then cover the soil, water it to keep the soil moist, and put earthworms.
7. Fat heap culture method. Stack the bait into a cuboid with a height of 3 ~ 10 m or a circular altar with a diameter of 5 m and a height of 0.5 m, splash water to keep a certain humidity, and put earthworms on it to raise. This method can be used in academic schools such as Tian tou, Tian bian, Fang Qian and Fang Hou.
Second, matters needing attention:
1. Earthworm farms need a good drainage system to prevent floods and rain. 2. The site is free of noise, smoke, gas and dust, far away from the fields where pesticides are used, well ventilated, with fresh air and no direct sunlight. 3. The four-season temperature of the breeding shed should be kept within the range of 5 ~ 35℃. In order to maintain proper humidity, water can be sprayed to adjust the temperature and humidity. 4. The breeding density should be reasonable. Generally, 40,000 larvae of about one month old are raised per square meter, and 2,000 to 4,000 adult worms are raised per square meter for the purpose of reproduction. 5. The bait should be loose, fine, cooked and rotten to prevent the bait from being too dry, with poor nutrition and incomplete fermentation. The collocation of bait should be combined with thickness to increase the permeability of bait bed. 6. To prevent earthworms from escaping, defend against the invasion of natural enemies such as maggots, ants, rats and toads, collect adult earthworms in time, expand breeding beds and avoid death. Earthworms feed on plant residues and eat a lot, and the daily food intake is about their own weight. All non-toxic natural organic matter can be used as artificial feed for earthworms after fermentation. Such as the feces of horses, cows, pigs, chickens and ducks. Leftovers of freshwater fish, rotten plants such as sawdust, straw, corn straw, rotten fruit, watermelon skin, vegetable edges, leaves, weeds, etc. Dry animal manure must be crushed, fresh manure should be diluted and fermented, and plant stems and leaves should be chopped and fermented. The method of fermentation is to mix bait with water and pile it up. The pile should be loose, trapezoidal or triangular in cross section, with a height of about 1 m, which takes about 2-3 weeks. The bait turns brown and loose, that is, it has been decomposed and can be used. The dosage of bait is based on the weight of earthworm. For example, if each adult earthworm weighs 0.4g, then 10000 earthworms can feed 4kg every day. It takes a long time to feed earthworm dung after recovery, and it can be fed in the morning and evening in summer, at noon in winter and day and night in spring and autumn. When there are few breeding beds, you can directly feed them, but there is more water at the bottom of the bed in this way, and earthworm eggs are not easy to hatch. A new bait bed can be set below or at one side of the original culture bed, so that earthworms can automatically enter the new bait bed from the original culture bed to eat.
Third, the source of breeding
Seed testers can make mixed fermentation piles with rich and fertile humus, feces, sawdust, straw, tea and rotten fruits. Lure earthworms out of a damp place suitable for earthworms to live in, and then raise them in the original pile, or pick them up before dawn the next day; Or catch earthworms in time after floods and rainstorms; Buy from wealthy families and farms that raise earthworms. Earthworms have degenerated heads, no eyes, adapt to burrowing, are hermaphroditic, and reproduce by cross fertilization, so reproduction is relatively easy and the reproduction rate is very high. In earthworm breeding, besides selecting excellent varieties, the temperature in the shed should be kept at 15 ~ 20℃ manually to ensure good ventilation and appropriate humidity, and 2 000 ~ 4 000 worms can be released per square meter, which can make earthworms mate and lay eggs all year round and further improve the fecundity of earthworms. Young earthworms look like a white line, young and weak, but their metabolism is vigorous, so the survival rate is high under suitable ecological conditions and no special artificial care is needed.
Fourthly, the collection and processing of wild earthworms
Wild earthworms are harvested from July to September. Generally, fresh Polygonum hydropiper grass is mashed, or tea oil cake is soaked in water, poured into a place where there are many earthworms, harvested and processed into dried earthworms when it escapes from the ground. The method of screen separation can be used to separate the earthworms raised in the field from the feces, that is, by using the characteristics that earthworms are afraid of light and heat, nets are placed below or above the feeding bed, and the earthworms are forced to separate through the screen through light or heat treatment, so that the small earthworms first pass through the small screen, and the big earthworms pass through the big screen, so as to achieve the purpose of separation. Earthworms can also be collected in an overturned wooden box, that is, when the weight of earthworms in the feeding bed is 0.4 ~ 0.5g, when the feeding box is placed in the sun or light, the earthworms will drill down, turn the box over, and the earthworms will be on it, so that they can be picked up by hand, which is relatively simple. After trapping earthworms, to process dried earthworms, you can first mix rice straw or plant ash, soak them in warm water, and wash away the mucous membrane outside the body, then nail one end of the earthworm to a board with an awl, and then use a knife or thin bamboo slices to break the abdomen. You can also grab one end of it by hand and laparotomy, wash the sediment in the body, dry it in the sun or distill it. The preparation method of earthworm powder is: the earthworm is washed with clear water, put into a vegetable basket and immersed in a container filled with boiling water. In order to burn the earthworm evenly, it is necessary to shake the vegetable basket constantly, and it takes about 4 ~ 5 minutes to burn the earthworm to death and cook it. Be careful not to take too long. After ironing, take the time to dry, break, grind and sieve until everything is fine. Earthworm powder is slightly thicker than flour. Generally, 2.5 kg of earthworm grinds 0.5 kg of earthworm powder.
