CATDOLL : CATDOLL: Is it reliable to farm earthworms? Zhihu (Is it reliable to farm earthworms? Zhihu article)

1. Is earthworm farming a scam?

Not all of them are scams. It depends on whether you find the right channel.

Earthworms can be farmed. Wild ones can survive on their own, and artificially farmed ones are even easier. However, there are many scams in earthworm farming. In order to make a profit, some unscrupulous merchants generally exaggerate the profits of farming earthworms in order to sell earthworm seedlings at high prices to make a profit. They claim on-site technical guidance, recycling guarantees, and zero-yuan purchase of seedlings. We must pay attention to these. For some merchants, we can't find the people even after we have paid the money, or we can't find anyone when we need technology. Everything has to be done step by step. No one can eat a big fat man in one bite.

What are the main methods of breeding earthworms?

The methods of earthworm breeding include: ecological breeding, three-dimensional breeding, mixed breeding of earthworms and snakes, greenhouse breeding, etc.

1. Ecological farming

The three most common types of ecological farming are forest farming, field farming and ditch farming. We usually choose plots with fertile soil and close to water sources for irrigation, because earthworms are more suitable for growing in a moist and fertile environment. After selecting the land, we need to dig trenches in the forest or field, which are generally about 40 cm wide and one centimeter deep. Then put organic fertilizers such as livestock manure into the trenches, and then cover them with a thin layer of soil. Finally, you can put the earthworms in for breeding. The breeding land should always be kept moist, but the water should not be too much, otherwise the earthworms will stop growing, remain the same size, and eventually die.

2. Three-dimensional breeding

There are many types of three-dimensional farming, including overlapping box farming, louvered box farming, tank farming, multi-layer cement rack farming, nylon mesh bed rack farming, etc., but the most commonly used one is multi-layer cement rack farming. This type of three-dimensional farming has the lowest cost and the highest efficiency. The only bad thing is that the space that can be used is limited, because the space of each floor must be so large, and some places in the room cannot be fully utilized. Therefore, for three-dimensional farming, we can adopt a variety of three-dimensional methods for farming, which can not only save costs but also improve efficiency.

3. Mixed breeding of worms and snakes

The mixed breeding of earthworms and snakes is also a relatively common breeding model, and it is very popular because its breeding efficiency is much higher than that of single earthworm breeding. Secondly, the living environment of earthworms and snakes is similar, so we can save some costs. It’s just that the mixed breeding of earthworms and snakes requires stratification. Its mixed breeding does not mean that they live on the same plane. There needs to be a layer between them so as not to affect the growth of the snake, and the snake venom will not poison the earthworms.

4. Greenhouse cultivation

Greenhouses are very popular nowadays. Whether it is the planting industry or the breeding industry, many of them need to use greenhouse technology, so as to ensure the normal growth of plants and animals to a certain extent. Therefore, greenhouse breeding of earthworms is also a common mode. We can use greenhouses to breed earthworms in greenhouses, which can speed up the growth of earthworms and improve work efficiency. In addition, the cost of greenhouse breeding is very low, so it can save a lot of costs.

What are the earthworm farming techniques?

1. Breeding site construction

Earthworms are very flexible in the soil. In order to ensure the breeding effect, they are generally raised in breeding boxes. The height of each box does not need to be too high, 30-50 cm is enough, but the horizontal area should be as wide as possible. The filling inside can be farmyard manure such as cow dung and pig dung, or some rotten leaves mixed with soil. The filling soil fluctuates around half, and in some places even all of it is livestock manure. The breeding box can be plastic or iron, and plastic is recommended.

2. Many people are raising earthworms now. Is this reliable?

Earthworms can be farmed, there is no fraud involved, so why are some people still deceived? Generally, they are some unscrupulous farms. In order to pursue profits, they will exaggerate the profits of farming earthworms by any means. Things like buying earthworm seedlings for zero yuan and guaranteed recycling are the beginning of the scam. These farms generally sell earthworm seedlings to you at a high price, and then nothing happens. Therefore, when farming earthworms, you must be careful, do more investigations, make more comparisons, etc.

3. What are the ten major dangers of raising earthworms?

There are both advantages and disadvantages to raising earthworms. The advantages include improving soil, processing rotten plants and animals including livestock and poultry manure, etc. But there are also disadvantages. I don’t know if there are ten major hazards, but there are at least two disadvantages:

1/ Transmission of parasites, especially pig lungworm;

2/The reason is that the flowerpot is small and there is little soil in it, so it will eat the roots of the flowers.

4. Is it reliable to breed Dilong?

Reliable and can be cultivated.

The breeding technology is not very difficult, the main thing is to control the temperature and humidity. Generally, the temperature suitable for artificial breeding of earthworms is 20℃-25℃ and the humidity is 60%-80%. From the natural environment alone, artificial breeding is more suitable for the southern region, but it is not impossible to breed earthworms in the north, but it needs to be raised in a greenhouse. However, the cost per mu is about 3,000 yuan more than in the south - the cost of building the greenhouse.

In addition, under a standard living environment, earthworms can be put on the market for sale after growing for about 2 months. Taking natural field breeding as an example, March to September each year is the peak sales season. After entering autumn and winter, the temperature is relatively low, and earthworms do not like to eat feed, grow slowly, and sales enter the off-season.

5. How about earthworm farming? What are the prospects? How much does it cost to invest?

2019 Earthworm Farming Prospects and Investment Analysis

Raising earthworms can make money. Earthworms feed on soil with organic matter, and they play an important role in clearing the soil aggregate structure and improving the soil. Artificially cultivated earthworms can be used as animal protein to supply livestock, poultry, and fish farming. Traditional Chinese medicine uses the dried body of the whole worm as human medicine, which has the effects of relieving fever, calming the nerves, and diuresis. Earthworm farming has not only opened up a new source of animal protein feed for the development of livestock, poultry, and aquaculture, but also found a new way for cities to purify the environment and deal with public pollution. With the in-depth study of earthworms, it can also provide valuable raw materials for industries such as food and medicine. Therefore, earthworm farming is a good way to get rich.

The Prospects of Earthworm Farming in 2019

1. First of all, earthworms have made great contributions to ecological farming in my country. The concept of ecological and healthy diet has been deeply rooted in people's hearts, and environmentally friendly green and healthy food is a product that consumers urgently need in the market. In terms of the current market situation, taking native chickens as an example, the traditional native chickens fed with full feed have gradually lost the market, but the sales of "ecological insect chickens" are very popular. At the same time, there is such a big difference in the sales volume and consumer popularity of native chickens. Is this just because of the addition of the word "ecological"? Obviously not, the meat of ecological insect chickens is more delicate than that of ordinary chickens, the flavor is more unique, rich in nutrition, delicious and healthy. A large part of this credit is attributed to "worms". Earthworms are one of them. Earthworms are rich in nutrients. Using them as feed can not only promote the growth of chickens, but also avoid many harmful additives, reduce costs, and promote the development of ecological farming.

2. Secondly, earthworms are high-quality protein feed. Earthworms contain a lot of protein. The protein content in dry matter can be as high as about 70%. The general analysis results can also get 41.62-66% crude protein. It is reported that earthworm protein contains a lot of amino acids, which are necessary for the growth and development of livestock, poultry and fish. Among them, the highest content is leucine, followed by arginine and lysine. The content of arginine in earthworm protein is twice that of peanut protein and three times that of fish protein; the content of tryptophan is four times that of animal blood meal protein and seven times that of beef liver. Not only does the body of earthworm contain a lot of protein, but also its feces contain a certain amount of protein. The Japanese Food Analysis Center has analyzed earthworm manure. When the water content is only about 11%, the total nitrogen contained in the earthworm manure is about 3.6%, which is converted to crude protein of 22.5%.

3. Then, earthworms are very supportive of environmental protection. Why do you say that? Everyone should know that earthworms have a strong digestive ability and can decompose a variety of organic matter and use it themselves. Raising earthworms to deal with garbage has become an environmentally friendly way adopted by many developed countries. With the rapid development of modern industry and agriculture, many industrial wastes have been discharged, causing serious public hazards. The large-scale application of pesticides has polluted large tracts of farmland, and the human environment has been seriously polluted, directly affecting human health. Such environmental pollution problems have attracted international attention.

4. It is understood that breeding 330 million earthworms can process 100 tons of papermaking sludge every day. Japan uses earthworms to process up to 3,000 tons of these wastes per month, and the United States uses 500 million earthworms to process 200 tons of industrial waste every day. The number of earthworms required is huge, and it is conceivable how much breeding space there is for breeders to use. It not only drives economic development, but also effectively solves some of the problems of environmental pollution. Breeding earthworms is indeed a feasible breeding project.

6. Is earthworm farming a scam?

Small-scale earthworm farming usually finds sales channels by itself and sends them to fishing tackle stores, which have long-term demand for them. The price is also acceptable.

Most of the large-scale farmers have signed contracts with processing companies, which is order-based production.
