1. Which one is more profitable, planting Gastrodia elata or earthworms?

A word of caution to friends who are interested in the animal husbandry industry: Be vigilant in the face of advertisements promoting the breeding of various animals, so as not to be deceived! ! ! . . [They are all difficult to serve. . . ]

2. What are the benefits of earthworm farming?

The profit of earthworm breeding is generally 1:3. Because it is a traditional Chinese medicine, the breeding prospects are promising.

Earthworm breeding technology

The living habits of earthworms. Earthworms are suitable for living in dark, moist, loose humus soil. In the wild, earthworms live in humus soil and gravel under kitchens, corners, and deciduous trees. They can burrow into the soil to a depth of 0.5 to 0.6 meters. They rest in the soil during the day and move around, forage, and mate after dusk. Earthworms are omnivorous insects with a wide range of diets. In addition to a small amount of concentrated feed, most of their feed is wheat bran, fine bran, and green fodder. They also eat various grains, animal residues, feces, etc.

2. Hatching earthworm eggs. Spring is the best time for earthworms to lay eggs and breed offspring. Choose a plastic basin with a smooth inner wall and a diameter of 50 to 80 cm, place 4 kg of eggs in the basin, mix in breeding soil that accounts for 1/2 of the volume of the eggs, and keep the humidity of the breeding soil at 40% (it is required to form a ball by hand and break when it falls freely). The thickness of the basin, including the eggs and soil, is 8 to 10 cm.

The breeding soil should be prepared in advance and placed in the incubator for preheating. The temperature difference should not exceed 5℃. During the incubation period, the temperature should be maintained at 25-30℃ (the best incubation temperature is 28℃). Turn the eggs by hand 2-3 times a day. The movements should be gentle to avoid damaging the earthworm eggs. After 35-40 days of incubation, a large number of larvae will break out of the shells. At this time, the larvae can be sieved out (using a 4 mm sieve). The sieved eggs are re-mixed with the breeding soil. The sieved larvae can be placed in a pool of 10 cm thick breeding soil for breeding. The larvae are sieved every two days.

Note:

The soil for feeding can be the topsoil from the vegetable garden, sieved with a 4mm sieve, and then mixed with 50% burnt rice husk (rice husk) ash. If you add some livestock manure or crushed crop straw and sawdust to make the soil more fertile and loose, the effect will be better. The standard of soil humidity for feeding is that it can be grasped into a ball by hand and will break into pieces when it falls freely. [Edit this section] Feeding and management of earthworms.

(1) Larvae feeding and management Larvae begin to eat after they have shed their first skin (about ten days) after hatching. At this time, they can be fed with wheat bran, fruits, pumpkin flowers, green vegetables, pumpkin shreds, etc. During the larval period, some nutritious food such as soybean powder, eggs, and milk should also be added. When feeding, just sprinkle the feed on the surface of the breeding pool, and the temperature should be kept between 25 and 32 degrees Celsius.

(2) Feeding and management of Chinese worms Chinese worms are managed in a relatively extensive manner and there are no special requirements for feed, as long as they can eat enough.

(3) Feeding and management of egg-laying worms Egg-laying worms require the soil to be 12 to 15 cm thick, and the feed requires green fodder and concentrated feed to account for 50% each. It would be better if a little soybean powder or animal meat scraps could be added to supplement the nutrition of the earthworms. The feeding amount is sufficient so that there is not much feed left on the surface of the earthworm pond by the next morning. The temperature in the breeding pond is maintained at around 25°C, and the humidity of the breeding soil is 60% to 70%. If the humidity is not enough, a pesticide-free sprayer can be used to humidify it, and the requirement is to use small amounts and multiple times.

3. What are the benefits of breeding earthworms?

The earthworms that come based on the scale and market conditions are not a violent industry. It is impossible to invest a few thousand dollars and make hundreds of thousands of dollars. The main thing is to see if you have an empty house, then do a good job of insulation, and then breed.

4. Benefits of breeding earthworms

The benefits are many times higher than other breeding and planting industries. Of course, as a long-term development project, farmers cannot sell all the finished products, but can select the best for breeding, and the benefits will naturally double year by year, and the breeding scale will be full of stamina. The earthworms of Zhengzhou Jinzun Technology Co., Ltd. can live up to 3 years and can produce offspring for 3 consecutive years. This is a one-time investment with long-term benefits. The annual profit of ordinary farmers can reach more than 100,000 yuan.
