Chapter 595 591. Qi Ruomu, where is your face?

It’s okay to fail once, there will be many more failures in the future.

Afterwards, Qi Ruomu used the covering method, soil alternation method, water immersion method, and adjusted the proportions.

Anyway, I tried nine times in a row, using all kinds of tricks, but all 3,500 kilograms of earthworms were wasted, and it didn't work once.

The tenth time, he started to change his tactics. He stopped releasing earthworms and only released earthworm manure, but did not release it directly. Instead, he mixed it with clean soil to turn it back into earthworm soil, which he then poured into the surface of the saline-alkali field in large quantities.

Anyway, we just use earthworm soil to dilute the saline-alkali soil and reduce the salt content in the surface layer first.

Reduced from 1.5 to 1.0.

Then introduce various salt-tolerant plants.

After four more failures, the salt-tolerant wheatgrass was finally chosen.

By the way, it was also measured that this thing can grow in soil with a salt content of 0.6~1.02.

Then the ice grass planting failed three more times. Some did not grow well, some were underdeveloped, and some died halfway.

It wasn't until the seventeenth time that the seed was finally planted successfully.

This is how we get this little piece of green blooming in the vast white salt...

The next follow-up plan is to use the salt absorption property of ice grass to continue to reduce the salt content in the soil. When it is lower than 0.6, deep plowing of the bottom layer is carried out, and mixing and dilution are continued to repeat the previous actions.

After all the temperatures are below 0.6, add earthworms and earthworm castings back into the reactor for biological improvement.

The purpose of this step is to improve soil structure and the microclimate of farmland, reduce surface water evaporation and inhibit salt return.

Qi Ruomu also gave it a name, called the "upper covering and lower modification" salt control and fertilization technology.

After using biological methods to add ice grass and planting it repeatedly several times, the salt content is reduced to 0.3.

Ordinary salt-tolerant forage grasses can be planted, and then earthworms and earthworm castings can be added to start adding fertility to the soil.

The purpose here is to generate economic benefits and achieve a positive cycle.

Afterwards, use grass and earthworms to reduce the salt content to below 0.1 and restore it to normal farmland.

The process is cumbersome and troublesome, but the good thing is that this type of land that was originally destined to be abandoned can be saved. Even land with such a high salt content can be improved, let alone other lands.

As for the difficulty, Qi Ruomu failed sixteen times and just completed the first step...
-
"There is another question." Qi Ruomu mentioned the current difficulty after showing off, "What can the grown ice grass be used for?"

"Is this edible?" Luo Yihang asked.

"It's edible. It's both a vegetable and a forage, but the salt content is so high..." Qi Ruomu shook his head.

Luo Yihang looked Qi Ruomu up and down, "You, you northerners have a large population, so you sell them all to the people in the imperial capital to mix with noodles."

"Regional discrimination." Qi Ruomu raised his eyebrows and immediately retorted, "First sell your father-in-law's house. He eats noodles three times a day, and the whole family is not done. When your wife comes home and sees it, she will be surprised to see a demon in the house~~"

Qi Ruomu is such a chatterbox.

Wenying held her forehead with her hands after hearing this. These two people should not meet. If they meet, they will fight. One is a servile person and the other is looking for trouble.

Can I still work properly?

"You two should calm down and talk about business."

Qi Ruomu shut up immediately.

Luo Yihang apologized immediately, "Oops, I forgot that you are also from the north, Wenying. You also have a strong tongue, and I accidentally hurt you."

Wenying sighed, didn't respond, and changed the subject back to the main topic.

"It's not realistic for humans to eat it. It's too high in salt and rich in harmful ingredients. Let's look for livestock breeds in agricultural colleges and universities to see if there are any pig, cattle or sheep breeds with strong flavors..."

After saying this, Wenying took a dip in it and was infected. She also said that too much salt in the food made her taste heavy.

Fortunately, the two instigators didn't realize it at all.

Luo Yihang also asked, "Why do we need pigs, cattle and sheep?"

“Because the demand is high.”

This time it was Wenying who explained to Luo Yihang.

Qi Ruomu is very ambitious.

The target is not the thousands of acres in front of him, nor the 70,000 acres in Hainan that are assigned to him, but the more than 200 million acres of saline-alkali land across the country.

Now, the more than 0.6 million mu of saline-alkali land are basically severely salinized, with a salinity of more than .

Most of the moderate and mild cases can still be grown, and when statistics are taken, they are calculated based on the impact of salinity and alkali.

There are so many saline-alkali lands, especially in the northwest, northeast and coastal areas, which are flat and large. If they can be restored, they can be developed into farmland.

No matter how much food and crops can be produced, even if only grass can grow, it is worthwhile to reduce carbon emissions.

Chinese people have never been afraid of having too much farmland, they only worry about not having enough to plant.

There has been no large-scale improvement, partly because the cost is too high. According to the most commonly used, fastest and best irrigation method, the investment to transform so much land would probably be tens of billions.

Second, a large amount of water is needed, and water resources are too precious.

If there is a technology that has low cost, provides profit compensation during the period, and does not produce a large amount of wastewater.

This is the biological transformation method developed by Qi Ruomu.

Once the technology matures, improving 200 million mu of saline-alkali land will only require subsidies of several hundred billion or even hundreds of billions of yuan, or even no subsidies at all.

The country will certainly strongly support and promote it. Believe it or not, it will all be transformed into farmland and grassland in a few decades.

so.

The target is 200 million mu, and it is best to base it on this demand when finalizing the technology, while crop use during the improvement period is related to the benefits.

Whether you make a profit or a loss by doing this job depends entirely on it.

The first batch planted was the ice grass, which had accumulated a large amount of salt and various strange substances, and is definitely not edible for humans.

When used for breeding, it is best to use livestock or poultry with high consumption, even aquatic products are the first choice.
-
It's really not easy. There are so many things to consider.

At first glance, there are difficulties everywhere.

No wonder Qi Ruomu said he wanted to stay in Hainan for several years.

If it really succeeds in a few years, he still wants to go to the northwest, and when he gets there he will have to do it all over again, re-select salt-tolerant plants, and redefine the proportions.

It also depends on whether his earthworms can survive in the bitter cold of the northwest.

Ugh.

Every level is difficult but you can get through it.

Back to the present.

None of Luo Yihang and his three friends knew anything about poultry and animal husbandry, so it was useless to think about it for a long time.

At most, Luo Yihang suggested adding processing and industrial use as options, and he would call on people when necessary.

Hey, that’s the point.

Qi Ruomu's true colors were revealed and he started to mobilize people on the spot.

The ones being shaken are Wenying and Luo Yihang who came to the door.

"Senior Sister Wen, please take some time to see if this ice grass can be further optimized. It would be best if it could absorb salt faster or have stronger tolerance."

Wenying agreed readily without asking Luo Yihang, as Luo Yihang had no objection at all.

Qi Ruomu was extremely polite to Wenying.

But when it comes to Luo Yihang...

"I have to say, the earthworms you raise are really good. I also set up an earthworm farm, but the ones I raise are not as good as yours."

Luo Yihang was about to be polite.

Qi Ruomu's next sentence was held back by Luo Yihang.

polite?

No need.

"So after the New Year, give me earthworm seedlings. Give me 100 tons first. There's a lot of earthworm manure. I'll take as much as you can."

Just open your mouth and ask for it.

What about the face?

Qi Ruomu is shameless, but Luo Yihang can't give it up.

I could only sigh secretly and nodded, "Okay, I'll go back and expand production for you."

Think this is over?

It’s early.

Qi Ruomu said again.

"I heard that you have a kid over there who is very good at farm machinery. He has finished his rotation with you and is familiar with all the steps. Please send him to me."

Even people are needed?

Luo Yihang's fist hardened, and he squeezed out a few words from between his teeth, "What do you want to do?"

"Designing agricultural machinery. I need help." Qi Ruomu rambled, "I have contacted people in the agricultural machinery field at the Academy of Agricultural Sciences, the Chinese Academy of Sciences, Imperial Capital Agricultural University, and Huazhong Agricultural University. I need a large number of special machines and equipment."

He even started counting on his fingers.

"The machine for separating earthworms from earthworm soil needs to be modified. The current method is too inefficient and misses too much."

"Equipment for rapid feeding and monitoring needs to be developed. Manual feeding is too inefficient and not suitable for large-scale farming."

"There are also equipment for quickly building earthworm beds and equipment for grouping. There are a lot of gaps in this area. Too many processes are manual and need to be developed from scratch."

“It’s better to make it modular.”

He asked for a lot.

As he was talking, he remembered something new and quickly wrote it down.

"We also need to prepare the right feed for the earthworms so that they can reproduce quickly and in large numbers. We also need to hire a few scavenger experts."

The hands were recording but the mouth was still talking.

Assign Luo Yihang another job.

"I have too many supporting things to do. Your place is close and has an earthworm farm. If they want to visit or study, they can go to your place. You can help with reception and docking."

Luo Yihang was speechless. "I need to provide people, materials, and reception."

"That's right, the summary is very accurate. Please send the earthworm seedlings to me as soon as possible. I'm waiting to use them."

This person is so shameless.

Luo Yihang's fists were hard...
-
Forget it, forget it.

Qi Ruomu is a bad person with a very dark heart.

I won't play with him anymore.

Go find the old man.

Which old man?

Qi Ruomu's father.

Tell the parents...
