Chapter 182 The second generation of earthworms (second update)

When the earthworm seedlings were harvested, there were more than [-], but this earthworm has a small characteristic, that is, after being divided into two parts, it can still survive.

Earthworms are special annelids with a head and a tail and certain organs.

However, its entire body is like two tubes sleeved together, the outer layer wraps the inner muscle system.What runs through the body is the entire digestive tract, which contains a lot of body cavity fluid.

When an earthworm is cut into two parts, its muscle tissue will start to contract, allowing some cells to dissolve automatically and become new cell clusters.

In this way, the cut surface will be blocked to ensure that the wound on the body will not bleed too much.

As the wound heals, the muscle cells begin to migrate and then form regenerative shoots to grow brand new parts.

Of course, not all earthworms can regenerate after being cut off, and there is also an element of luck.

In the phylum of earthworm annelids, it is a relatively complicated existence.It has a digestive system and a circulatory system, and a large number of blood vessels are also distributed.

If the cutting position is wrong, the muscle will not be able to block the cutting wound during the contraction process, and the earthworm will lose too much blood and die.

Generally speaking, it depends on whether the cutting position is correct. If the position is correct, regeneration will be easier.

Xiao Jinli carefully selected a batch of strong and vigorous earthworms, cut them off manually, and then put them into the nutrient soil that she carefully prepared. Even if the cutting position is wrong, there is enough spiritual spring water in the nutrient soil, which can Allow the worms to heal the wound quickly.

These truncated earthworms quickly changed from one earthworm to two earthworms.

Therefore, there were 20 earthworms at the beginning, but now they have doubled, and together with the self-reproduction of earthworms, it has become more than [-].

Earthworms are very capable of reproduction.It is a hermaphrodite, and lays eggs once a month, and many earthworms emerge from one egg.

Due to the large base number of earthworms, the total reproduction rate is still very large.

Xiao Jinli took the earthworms he bought back then as the first generation.

The first generation of earthworms was bred and raised entirely by watering Xiao Jin carp with spiritual spring water.

When they reproduce by themselves, the earthworms produced come from the nutrition of the mother. Their growth size, nutrient base, and survival base are higher than the mother's, and they are marked by Xiao Jin as the second generation.

However, the second generation of earthworms reproduced became a new batch of seedlings.

As the mother of the second generation of seedlings, Xiao Jinli carefully selected it again.

These mother bodies were placed in another piece of nutrient soil.

Mature earthworms can reproduce once a month, and in three to four months, one earthworm can reproduce twenty or thirty earthworms.

Xiao Jinli looked at this huge breeding land of more than five acres, and felt that it might not be enough at all if it went on like this.

Therefore, in the second year, she expanded the earthworm breeding ground and built another greenhouse.

After Xiao Yucheng became the general manager of Xiaojia Village Green Fresh Company, he has a special future plan for the earthworm farming of Xiaojin carp, which is the most important key project.

After all, the development of planting in the whole village and the hope of getting rich all depend on these earthworms.

Therefore, [-] mu of land was specially set aside for the construction of greenhouses for future earthworm breeding.

Except for the first five acres of land, which is used for Xiaojin carp research is a private base, and the next five acres of land also belong to her research base. The company compensates for the earthworms and seedlings she raised for the company.

After the [-] mu of land was set aside, it was subdivided by Xiao Jinli and used to breed the second and third generation earthworms respectively...

Since these earthworms are bred from the mother body, their physique is better than the first generation from the very beginning.

Therefore, the value of these earthworms is actually higher than that of the first generation, and they are survival of the fittest. They inherit all the advantages of the previous generation and remove all impurities. They are better than the first generation. They are used for planting, and the quality of the things grown must be better. good.

Of course, Xiao Jinli hasn't told the villagers yet.

Now, everyone is working together to pour the first generation of earthworms into the ground one after another. Each earthworm is as thick as an adult's finger and as long as a chopstick. Those who are afraid of crawling soft animals have dense fear People with the disease are very scared when they see it.

It's only the second month of the lunar calendar, with nearly [-] mu of land, and the weather is still very cold, but the villagers have already planted all the seedlings that can be planted, such as peppers, eggplants, cabbage, watermelons, etc.

The remaining land is more than [-] mu. In addition to the planned rice planting, there are [-] to [-] mu of land for flexible use.

From plowing the land to planting earthworms, the whole village has been busy for more than 20 days, because according to the company's requirements, pure green vegetables and fruits are planted. Therefore, this fertilizer, except for the earthworms, is all organic farmers. Fertilizer, without using any chemical fertilizer mixture or the like.

"Yucheng, what are pure green vegetables? And what about this green food?"

A villager asked.

Xiao Yucheng explained, “Green vegetables refer to non-polluting, safe, non-polluting vegetables that follow the principle of sustainable development, are produced in accordance with a specific quality standard system under the premise of a good ecological environment in the place of origin, and are certified by a special agency to allow the use of green food labels. A general term for high-quality, nutritious vegetables.

Green vegetables refer to the indicators of pesticide residues left in vegetables after the use of pesticides in the production process of vegetables, which are lower than the national or international standards.

We not only want to create green vegetables, but also try our best to create green food, such as the chickens and ducks we raise.

Green vegetables are just one type of green food.

5 criteria that green food needs to meet:
Standard [-]: Products or product raw materials must meet the quality standards of green food ecological environment.

Standard [-]: crop planting, livestock and poultry breeding, aquaculture and food processing must comply with the operating procedures for green food production.

Standard Three: Products must comply with green food and hygiene standards.

Standard [-]: The outer packaging of the product must comply with the general standards for national food labels.

Standard [-]: Comply with the specific packaging, decoration and labeling regulations of green food.

Green food ratings are further divided into two categories: Class A and Class AA.

Grade A green food

In addition to meeting the above standards, it is necessary to limit the use of limited chemical synthesis production materials, and actively adopt biological methods to ensure that the product quality meets the requirements.

In addition to meeting the above standards, AA. grade green food uses organic fertilizers, green manure planting, crop rotation, biological or physical methods and other technologies in production to fertilize the soil and control diseases, insect pests and weeds. "

"So, our goal is to make the things created by our village into AA-class green food, sell them all over the country, and make them our green brand!"

Most of the villagers did not have much education and could not understand Xiao Yucheng's explanation, but they still understood the last sentence.

passionate!
