Speaking of fertilizer, Su He remembered what he thought before.

Originally, he planned to invite someone to go to the back mountain to pick up the tung zi, but since he said this, Su He smiled and said.

"As for fertilizer, don't worry."

Su He's words made Ye Zhenhan roll his eyes: "There is no shortage of fertilizer everywhere in China now, do you think there is no need to worry?"

Su He said naturally: "Of course, I remember there was a tung tree in the back mountain, and we were wasting all the tung seeds. The previous ones fell to the ground. These tung seeds are a good thing."

As he said that, he looked at the grandpas with a smile.

Ye Zhenming slapped his head: "Indeed, this thing is a good thing. Tung oil can not only be burned, but also the oil produced by tung seeds, and the remaining residue seems to be a good fertilizer. We have ignored it."

Ye Zhenbin also suddenly realized: "As the saying goes, thousands of brown trees, thousands of tung trees, and their descendants are endless."

The truth of this sentence is that if you plant these two kinds of trees in your family, your descendants will not be poor without working.

The whole body of the palm tree is full of treasures, and brown hair is widely used, and the straw raincoat is made of brown hair.

In addition, mattresses, hats, brown ropes, insoles, fans, etc. can all be used for brown hair.

The wood of palm trees is relatively corrosion-resistant and is often used to build bridges.

Even the leaves of palm trees are very practical and can be used to bind a lot of things. Moreover, palm trees have strong vitality and long lifespan, so they can thrive without any management.

Let’s talk about tung trees, which was also a very important economic plant in ancient times.

One of the biggest uses is to use the fruits of tung trees to squeeze tung oil.

It is a very important industrial oil. In the past, every household in rural areas had to make furniture, so they needed to use tung oil to protect the furniture.

This is a very good anti-corrosion coating. Many cold weapons can also be used as protection.

Because tung oil has the advantages of fast drying, anti-humidity and corrosion resistance, glossiness, and light specific gravity.

The price on the market is also not low.

Tung oil can also be widely used in industries such as industry, agriculture, and fishery.

Moreover, the tung cake after oil-pressing of the barrel of oil is a very efficient farm fertilizer, which is very useful to farmers.

Ye Zhenhan was stunned, then patted his head and said, "I am still true. I am a little blind when I keep my treasures in sight."

However, Ye Zhenming said: "We have this palm tree here, but not many. Next, I think we can plant some palm trees ourselves."

Su He opened his mouth and finally did not refute.

Ye Zhenbin noticed his hesitation and asked with a smile: "If you have anything to say, we are all your elders. If you say it wrong, can you scold you?"

Su He pursed his lips. Didn’t grandfather scold me just now?

Ye Zhenhan frowned and stretched out his hand. Su He quickly said, "The economic value of palm trees is still OK. But if we don't consider the subsequent production materials ourselves and consume them ourselves. It will be difficult for people to find someone to acquire these materials.

From now on, everyone uses umbrellas and raincoats, who still uses a straw raincoat?"

It’s not that the straw raincoat is bad, it’s just that there are more convenient tools, and probably no one will use them again.

Unless you take a tourist route, tourists can come to experience it at most. Who really buys a straw raincoat and goes back?

When to collect it?

However, Su He changed his mind: "If the furniture factory of Grandpa Fifth can be opened, it can also be used for mattresses or something in the future. Brown hair can still be used."

Ye Zhenming's eyes were deep: "No more care, let's get stuck for the time being. But we can always expand the planting of this tung tree, right?"

Su He nodded: "This is OK, and I remember that in "Ye's Medical Classic", there are methods and formulas for making fertilizers with residues from tung oil fruits after oil extraction. This is our strength. But we must keep it confidential, this formula,

It is possible to build a factory. In the future, we can buy tung oil fruits outside and make a lot of fertilizers. Maybe it will sell well across the country."

If you use too much fertilizer, it will actually have an impact on the land.

In addition, the vegetables that have used chemical fertilizers are not as good as vegetables that use farm fertilizers.

People in later generations all pursued these pure natural vegetables that had never been used for fertilizers.

More nutritious and healthier.

This natural fertilizer is much better than chemical fertilizer.

Ye Zhenming nodded and told Ye Zhenhan with a serious expression: "From the future, no one else will go to your study. We all..."

After thinking for a long time, Ye Zhenming suddenly said, "Let's give those books to He Jiezi."

As he said that, he turned around and said to Su He: "We will give you those books. Although you are not from the Ye clan, you are also the grandson of the Ye clan, and you are considered to be our family. All those books will be entrusted to you.

.If someone from the Ye clan is willing to study medicine in the future, he can go to your place to read books. But if no one is willing to study medicine, all those books will be given to you."

As he said that, Ye Zhenming sighed: "After all, no one is willing to inherit the wisdom of our ancestors. It's pitiful, it's a pity."

Su He wanted to say something, but Ye Zhenhan nodded directly and replied: "Then He Jiezi, you can find time to move all the books away and save them properly. You can give them all in the future.

It is inevitable that someone will have ideas if it brings huge wealth.”

If you are a human, you have your own ideas. People from Nanzhu Village are still quite obedient at present.

Most people are quite simple.

But what about the future?

Will anyone not be able to figure it out when they become rich in the future?

In addition, some people may have ideas that if they sell the recipe, they can get a lot of money, and some people will be willing to do so.

If others don’t say it, Aunt Lele will definitely be willing.

Ye Zhenbin said in a deep voice: "In the future, when we get married in our village, we must look at their character more. The people in Shanlan Village are greedy and are the most unfair."

Ye Zhenming waved his hand: "Shanlan Village is not all like that. It's just that a few of them are not good, we have all married them. Besides, it's their own business for the villagers to marry, and we can still do arranged marriages.

Can't it be done?"

After this topic was revealed, Su He also sighed that at least the grandfathers today are old, their thinking is not worse than that of young people.

The speed of accepting new ideas is no slower than that of young people.

Even more enlightened than young people.

How could Nanzhu Village not be rich under their leadership?

Afterwards, he said something, Ye Zhenhan took the money into account and kept the account.

Afterwards, Su He followed Ye Zhenhan back and moved some books and left.

Su He naturally put these books in the library in his portable warehouse.

What else is more hidden and safer than your own warehouse?
