Agriculture Idol

Chapter 103 Soil and Earthworms

Although everyone knows that Geyue Entertainment's top floor project still has a lot of work to do, Qi Lanting and Brother Xiaoyong really don't have time to spare.

Qi Lanting, as a popular idol who is gaining momentum, can run 30 announcements a week.

As for Brother Xiaoyong, a newcomer, he had reserved two new films before, but due to the return of Li Chengxin's parents, he skipped the ticket for two months.Fortunately, Yuan Zhao was very capable and Geyue Entertainment was powerful, so he was not kicked out of the crew. Now that he is back, he has to busy filming a lot of scenes.

Therefore, Li Chengxin was the only one who performed the live broadcast in the end.

Li Chengxin just released an album at the beginning of this year and is still saving new songs for the next album.

Then because his parents came back, he missed the most popular period of variety shows, so Yuan Zhao postponed his activities to the next year. Therefore, now in the two months of October and November, Li Chengxin is unexpectedly free, only Need to do this live show on the top floor of Geyue Entertainment.

But on the other hand, such heavy physical work as construction is the activity least suitable for Li Chengxin, a literary young man.

So Zhou Hao, a tool man, was finally pushed in front of the camera, mainly used to help Li Chengxin do physical work.

"Fortunately, it's not a show about singing, dancing or acting. I feel like it's a fitness show. My father can still accept this." Zhou Hao comforted himself silently. Before he became Li Chengxin's tool man, he opened a gym and occasionally posted some workout videos.

Before Brother Xiaoyong said goodbye to Li Chengxin and went to the crew, he explained in detail to Li Chengxin and other crew members the issues he mentioned before about how to deal with the soil excavated from the release pond.

The soil they dug out from the release pond before was deemed "unusable" by Brother Xiao Yong after it was dried in the sun.

Due to the richness of fine sand, the dried mud at the bottom of the pond cracked into very hard and solid lumps. Even if it was broken with a hammer, it would only turn into fine sand dust.

In such hard soil, it is difficult for plant roots to grow.

According to Brother Xiaoyong, there needs to be gaps in the soil.

Brother Xiaoyong and Li Chengxin have been exposed to various soils in various agricultural live broadcasts, and they can tell whether the soil quality is good or not.

In addition, because of the fine texture of these soils, the excessively dense clay soil between particles will not only cause poor drainage, but will also become hard once it dries again.

Li Chengxin and the program team immediately felt the seriousness of the situation when the soil that had been produced after spending so much energy and battle was not usable.

The mud at the bottom of the pond must be very nutritious, but is there any way to change the soil quality?

The answer given by Brother Xiaoyong is "yes".

The purpose of soil itself is to cultivate organisms. The more organisms living in the soil, the better the soil quality will be.

Earthworms are an organism needed for healthy soil. In the process of eating soil, earthworms can improve the soil.

It can gather fine soil particles, form the so-called aggregate structure through the mucus in the body of the earthworm, and then be excreted by the earthworms to become large soil particles.

This is the agglomeration of soil, which is the result of Darwin's research.

The last book in the life of Darwin, who is famous for his theory of evolution, was "The Production of Humus and the Function of Earthworms", which also became the first important work in the field of soil bioturbation.

Recent studies have shown that the aggregated soil species excreted by earthworms also contain water and nutrients, which are conducive to the reproduction of bacteria in it.

In "The Production of Humus and the Function of Earthworms", Darwin wrote that "the earth was created by earthworms". Therefore, in theory, no matter how difficult to use the soil, after being improved by earthworms, it will become suitable for biological survival.

However, they previously collected more than 600 kilograms of soil, and it would take 100 years to complete the improvement of 10 earthworms.

Fortunately, using some modern additives, the same effect as earthworms can be produced artificially.

With this conclusion given by Brother Xiaoyong, the hearts of several people who were suspended by "ten years" were finally relieved.

These dry soils like now need to add some sticky additives, and the source of this additive, natural products will naturally be better than chemical additives.

"Actually, kelp or seaweed is a very good natural sticky substance." Brother Xiaoyong scratched the back of his head with a smile, "The copper algae, a special product of Hongming Village, was very good in the past. Its sticky component is alginic acid."

Alginic acid is a component that kelp or seaweed stores for self-protection and does not dissolve even in water.Because of its strong viscosity, it is now often used as a raw material for some foods and cosmetics.

However, almost 600kg of kelp is needed to change 100kg of soil.

Although Lanhai City is close to the sea, it does not have the conditions for kelp or seaweed farming. After going around for a while, Li Chengxin planned to go back to Hongming Village.

Hongming Village used to specialize in a kind of algae called copper algae. Copper algae often form seaweed forests and can reproduce in large numbers in late winter and early spring every year. They can grow about one meter in height every day and can reach up to ten meters in length.In addition, copper algae can be used as a compost or seasonal food, and can even be developed into a raw material for bioethanol.

Copper algae are mainly distributed in the temperate seas in the north, and the sea area near Hongming Village. In recent years, copper algae forests have been eroded by sea urchins that multiply.But as sea urchin farming began, copper algae forests began to reappear in the waters adjacent to the village.

This time back to the village and getting off the bus at the entrance of the village, Li Chengxin felt an obvious difference.

Not only have there been more faces from other villages, but several families from this village have also moved back from other places. Old houses that have been vacant for a long time have been demolished and new houses are being built.

Li Chengxin saw Uncle Zhengwen and Uncle Zhengwu, with a few young workers, building a new house not far from the village.

The lively scene on the construction site and the crowd watching and chatting near the construction site brought popularity and vitality to the village.

Li Chengxin really felt the changes in the atmosphere and the main people in the village, and felt that the village changed from old age to middle age in the blink of an eye.

Li Chengxin, a young worker, also met them. They were migrant workers who helped Zhou Hao build the resort. They were supposed to leave with the foreman after the resort was completed to take on new jobs.

Unexpectedly, various construction activities were also going on in the village. Uncle Zhengwen and Uncle Zhengwu thought that they were too busy, so they recruited these workers as well.

Li Chengxin went up to greet them, then turned and walked towards the resort outside the village.

He didn't bring anything home this time, and he didn't need to go home to put his luggage first, so he planned to go directly to the resort to meet his parents who were working there.
