The whole family travels through time: escape from famine! No cheat codes yet!

After the seeds are collected, they should be placed in a ventilated and cool place to dry, and not exposed to direct sunlight. The same applies to the bark.

However, when planting, if it is planted directly without germination treatment, the germination rate is very low, only about 60%. If it undergoes a germination treatment process, the germination rate can reach more than 80%, or even 90%.

This is because the seeds of the Eucommia ulmoides tree are in a state of shallow dormancy. The current technical treatment methods include sand storage, warm water soaking, and of course a plant hormone treatment method. She cannot get the things she needs for the time being, so I won't go into details.

The sand storage method is also rather troublesome, so if she were to plant the seeds, she would rather use the warm water soaking method.

You just need to soak the dried seeds in hot water at 50 to 60 degrees, stirring while pouring. After the water cools down, change it to warm water at 20 to 30 degrees. Change the water once or twice a day. After two or three days, take out the seeds after they swell, dry them slightly until the seeds can naturally disperse, and then you can plant them.

Of course, you can also use cuttings, layering, root suckers, root retention, root cuttings, grafting and other seedling raising methods.

But now they are fleeing from famine and don't know when they can settle down. It is not a good idea to carry branches with them, so they can only wait and see.

The most important thing is that the bark of the Eucommia tree is not the only one that can be used as medicine. The roots, flowers, leaves and fruits all have medicinal value, but many people today don’t know this yet.

Its leaves and flowers can actually be fried and made into tea.

After being dried, the leaves and flowers of the Eucommia tree have a unique color and refreshing fragrance. They not only have the effects of clearing away heat and detoxifying, moistening the lungs and relieving coughs, but are also a good product for quenching thirst and maintaining health in summer.

In particular, the male flowers of Eucommia ulmoides, that is, the flowers of the Eucommia ulmoides tree, have a mellow taste and fragrant aroma. It has calming, sedative and analgesic effects. Long-term use can significantly improve sleep.

The bark can be used as medicine, tea, wine, food therapy, and many other uses. The seeds can also be used to extract oil, not to mention the rubber. For them, it is a treasure.

"Yo yo, what are you doing? Why are you grinning like an idiot? Hurry up, the basket is full."

Shen Dabao was standing on a tree branch, lowering a bamboo basket tied with a straw rope.

Shen Youyou came to her senses and quickly took it and poured it into the sack in front of her. Dabao pulled it up again.

The seeds and fruits are separated. Pull up the basket for seeds, and put down the bamboo basket for fruits.

Shen Youyou poured the fruits into another bag.

Shen Zhiqiu, who had just finished cutting one bark, came over and prepared to cut this one. As he moved his knife, he asked Shen Youyou, "What were you thinking about just now? Dabao called you several times but you didn't hear him? Why do you always want to be happy every day? Can you tell Dad about it?"

"I think the whole body of Eucommia ulmoides is a treasure, and it's worth buying a barren hill to plant it."

Shen Youyou said it so lightly that Shen Zhiqiu was so scared that he almost cut his hand with a knife.

"My daughter, you will spend money in the future. Planting Eucommia trees will take at least ten years to grow. Don't think about it."

“The leaves and flowers of the Eucommia tree can be made into tea in ten years.”

The corner of Shen Zhiqiu's mouth twitched: "Isn't ten years long?"

"Just plant it first, and you can harvest it in ten years. You can't eat hot tofu in a hurry."

Shen Zhiqiu said nothing. He was worried about the future livelihood of this group of people. He was crazy to spend money to buy a mountain in advance and start reaping the benefits 10 years later.

Seeing that his father didn't say anything, Shen Youyou knew that he didn't agree, so he thought, "Forget it. I'll make more money when I get to the place and buy it myself."

As a result, Shen Youyou remained silent. Shen Zhiqiu thought his daughter was angry, so he coaxed her in a gentle voice: "My daughter, it's not that I won't buy you one. Just ask daddy to wait for a while and let him earn some money. Once you have solved the housing and food problems, I will definitely buy you a big house."

Knowing that her father had misunderstood, Shen Youyou tried to comfort him: "I plan to cooperate with my mother and grandmother to make a lot of money and buy a mountain of my own."

Shen Zhiqiu was stunned. Was she going to give up on him so easily? Was she not going to play with him anymore?

Could it be that providing him with retirement benefits was a lie?

"You, then tell Dad what big business you are planning to do?"

"Shoe soles, rain boots, snow boots, crystal shoes, sandals, slippers, any kind of shoes will do."

"You are really going to fight with the shoes, why don't you cooperate with your father?"

"We can work together, the whole village, to expand the scale and sell to every county." Shen Youyou talked about her shoe business.

Shen Zhiqiu narrowed his eyes in a smile. His daughter was quite ambitious, but: "It will take fifteen years for your business to be successful, and you have to sell the hilltops and plant trees as soon as you settle down. To put it bluntly, you still have to plant trees first. Even if we collect all the raw materials here for you to make rubber, your output will not be enough to sell for long, right?"

Shen Youyou rolled her eyes and gave her father a proud look: "Who told you that I can only use Eucommia ulmoides rubber as raw material?"

This time Shen Zhiqiu was really interested and asked, but Shen Youyou didn't intend to say anything.

On the women's side, they were sticking their butts out collecting dry leaves from under the trees. They didn't know what to do with these leaves. Could they sell them for money?

Shen Youyou took the opportunity to take a look and started thinking about making rubber shoes. The more she thought about it, the more annoyed she became.

When I first saw the Eucommia tree, my head felt hot, but when I saw the dry leaves, I cooled down and became sober.

When she came back dejectedly, her father had already started moving to the next tree.

Shen Youyou was worried. Under the current conditions, it was very difficult to extract rubber. There was nothing she could get. She could only go through more complicated steps.

Forget about efficiency. It is impossible to obtain strong alkalis such as pure sodium hydroxide, but you can try to use natural alkaline substances such as wood ash to prepare alkali solution.

In the step of extracting rubber, it would be very difficult because there were no modern chemical solvents and extraction equipment in ancient times.

In theory, you could try soaking and stirring with natural solvents like vegetable oil or animal fat, but the results might not be ideal.

Another possible approach is to try to separate the rubber component by repeated boiling and filtering. But this would be a long and inefficient process.

After the rubber components are extracted, they are purified and collected. Let’s talk about purification first. Under ancient conditions, this may mean removing impurities through further filtration, washing and drying.

Eventually, the purified rubber is collected and used to make a variety of items.

It should be noted that the above steps are only proposed based on modern knowledge and speculation about ancient conditions.

As for actual operation, due to the limitations of ancient technology and resources, extracting rubber from Eucommia seed skin may be more difficult and inefficient.

If fresh leaves are used, extracting rubber may be easier, but she doesn't have that many containers for fermentation.

They are fleeing famine now, and the situation is getting worse and worse. I don't know when I can make a pair of shoes for them all. It's really annoying.

Shen Youyou felt her scalp itchy and scratched it for a while. Suddenly she stopped and said, "Ah!"

A scream was heard, and Dabao on the tree was startled. He lost his balance and slipped, and fell directly from the tree more than two meters high.

"Plop!" It sounds very painful.

But he didn't care about the pain in his body. He quickly stood up, jumped over and pulled Shen Youyou's arm: "What's wrong, Youyou, were you bitten by a snake? Where was it bitten?"

"Where was you bitten?" Li Jingshu and Shen Zhiqiu, who rushed over first, asked in unison.
