The arrival of Shen Jihua and Shi Yudan was welcomed by everyone in the "Red Famous Village Base". They were almost sent to the depths of the "Red Village Base" by two columns of people who lined up to clap and applaud. When they reached the depths, the two of them froze at the same time. They did not expect that in such a deep mountain, there would really be such a military base.

At the dome of the cave, some light bulbs emit a not-so-bright glow. But this is enough to make people see the road clearly, and not to hit the hanging bells. In the largest part of the stone wall, which has both a training ground and an arsenal space, there are already quite a few other facilities at this time.

For example, the automatic water supply device is simply a hand-cranked water pump that is common in China and is attached to a rotating log. This gives it the power to pump the water upwards and upwards. At the height of the face wall, a wooden water tank is built. Some bamboo pipes with similar diameters carry clean water wherever it is needed.

"I'm sorry, the conditions here are poor, please eat a little bit for the two generals!"

The daily food of the "Red Famous Village Base" is nothing more than some rice, noodles, oil, canned meat from Japanese munitions, and other foods that can be found in nearby cities and villages, like snot. Although it doesn't look good, it's well nourished.

Like Jin Tao and Charlene. Luo, eat something like this as well. Bread is the only staple food, and at most there is a vegetable soup made from wild vegetables found on the hillside with a little salt. So everyone's cutlery is basically a plate with "snot", a cup with wild vegetable soup and a piece of bread.

However, the food eaten by the newcomers Shen Jihua and Shi Yudan today is more normal. The two of them had more bread than the others, and there were beaten eggs in the wild vegetable soup, and as for the plate, it was the result of two people sharing a Japanese military can.

"Where, where, the two of us are here, all to follow the commander to do great things against Japan, it doesn't matter what we eat!"

When speaking, Shi Yudan habitually shook his goose feather fan, and with the other hand, he stroked his own three-way long hair with fairy wind bones. For food, apparently there is not much interest. Presumably, people like him are more interested in vegetarian food.

So I just ate bread and occasionally took a sip of wild vegetable soup. However, because Shen Jihua lives in Germany, he is no stranger to the combination of bread and canned meat in front of him. For the eyes Charlene. Luo replaced Jin Tao's politeness, and his answer was full of honesty.

"You're welcome, I know it's not easy here, I just want to see what the commander said about the planting system."

Jin Tao is not polite, and he is often not polite to people he trusts. Probably this is not always what politicians should have to say, so Charlene. Luo often said these kind words for him on such occasions. Shen Jihua's words aroused Jin Tao's interest, because he asked Shen Jihua to come here, not only to solve the total amount of the current "Red Famous Village Base", but also to solve the total amount of food for the Chinese in the future.

There is not much gossip, and after eating, as a medical worker, it is natural to go to the hospital. Thinking about Shi Yudan, who is quite immortal, wants to have a relationship with that American medical doctor David. Dr. Holden was a good dealer. Jin Tao hopes that there can be unbiased exchanges with each other, and that China's traditional medicine can be integrated with the world's "advanced medicine" at the moment, and form an "advanced medical system" that China will have in the future. For this he wants Charlene. Luo compiled the information about Chinese medicine on his EEEPC.

But there is really not much information, and Jin Tao also feels that in addition to the progress of traditional Chinese medicine preparations in the future, in fact, the research of traditional Chinese medicine may shrink and regress after the founding of the People's Republic of China. As a kind of medicine based on health preservation and disease prevention, it is obviously two medical methods that belong to different paths and the same end as the Yankees' "cure" medicine.

The person who discusses who is good and who is bad in the two types of medicine is a 2b in Jin Tao's eyes.

His question is very simple, who is good and who is bad in the palm of the hand and the back of the hand? If the person who discusses such a question has not been kicked in the head by a donkey, he must have been caught by the door!

However, this matter is not urgent at the moment, what is urgent is the problem of eating. This is the question that Shen Jihua, who left the dinner table with Jin Tao, is eager to understand.

As we mentioned earlier, the "Red Village Base", which has a huge space with a training ground and an arsenal up to several tens of meters high, is undergoing the construction of future "farmland". The so-called farmland is that Jin Tao has seen the three-dimensional cultivation technology, and this technology simply frightened Shen Jihua, a German student in front of him, for a moment.

Three-dimensional wooden frames with some waterproof canvas from open holes, apparently from the Japanese. At the top of these square pillars, water pipes formed by bamboo pipes act as a watering system. And the three-dimensional cultivation prepared by Jin Tao is to use simple things. Shen Jihua faced an open column and looked at the system inside in detail. Inside are many layers, built into a thin bamboo pipe with the word "well", and under Jin Tao's introduction, Shen Jihua finally figured out how it operated.

"Mr. Shen, our fertilizer water enters the column through these thin bamboo pipes, and then re-enters the system through the return pipe below. It was filled with rice husks and scraps of sand, gravel and other light materials, and then we planted crops like potatoes and sweet potatoes in it. My concern is that the effectiveness of these fertilizers will gradually decrease, which will affect the growth of crops......"

Listening to Jin Tao's introduction, Shen Jihua's eyes widened and widened. Wearing glasses, he couldn't help but take a good look at the system in front of him, and then looked at Jin Tao again. is still the same sentence, he doesn't believe that in this world, a general who can fight can actually make such an advanced three-dimensional cultivation.

The reason why it is advanced is because if it can be planted with pillars built on a shelf on a stone wall, then one day if there is a large piece of land, it will be possible to carry out such three-dimensional cultivation as well. This would maximize the use of the land, and such a system would obviously not depend on the fertility of the land itself, i.e. any land that could be leveled could be used for such agricultural production.

――――――――――――――――――――――――――――――――――――― believe that modern people have no doubts about stereoculture, but in 1937 as a branch of hydroponics, stereoculture had not yet been used. There is no one like Jin Tao to do such a thing in a cave in the enemy's war zone. When Shen Jihua came here, he was still thinking that perhaps the most suitable thing in the cave was to grow mushrooms, but he didn't expect that Jin Tao planned to grow everything like this.

"Fertilizer is our processed manure and straw, grass and fallen leaves on the hills outside. We first crush them and then produce biogas to meet our fuel and chemical needs. The residue of the biogas and the water then form a fertilizer for infiltration, and the residue forms a substrate with the lightweight material just mentioned, which is placed into these columns to act as soil. In that case......"

Shen Jihua is worthy of being a figure who studied agriculture and animal husbandry in Germany, and he quickly understood Jin Tao's masterpiece of painting cats and tigers. With the substrate, osmosis is mainly supplemented with water, and at the specific growth stage of the plant, the biogas residue is used as a supplementary water fertilizer. If the whole system works well, then it will be able to provide a considerable amount of food to the entire "Red Village Base".

Especially for plants with a lot of starch, such as potatoes and sweet potatoes, he can almost foresee that in the future, the branches and leaves of these plants will be mixed with human excrement to form the raw material of biogas. As for what biogas can be used for, it is believed that there are many places in the cave that need lighting and fuel.

Even if Jin Tao has the ability to do so, he can even use biogas to generate electricity. After all, this is a car that uses gas in China, and it is believed that the engine that can use gas can be used to generate electricity using biogas with a little modification. Although Shen Jihua felt that these things that Jin Tao showed him had greatly expanded his thinking about agriculture and animal husbandry, and he had even seen agricultural production based on industrial standards.

"My God, what kind of head can come up with this!"

Yes, three-dimensional cultivation can be said to be the absolute development direction of human beings in the future, for example, if you are interested, you can search for vegetable factories, according to the understanding of not smiling, an Austrian vegetable company can produce 1000 kilograms of vegetables per square meter in a year. Undoubtedly, it is definitely the result of three-dimensional cultivation, otherwise it would not have been possible to have such a yield.

And humans can build a building to 800 meters or more, so what is the yield?

These are the things that Shen Jihua can think of based on what he has learned, but Jin Tao's following words can make him understand that the scope of his thinking is still narrower. He was able to understand that this would solve the problem of feeding the "Red Village Base", but he did not know that what he was going to carry out was to solve the problem of feeding one-third of the people in this world in the future.

This is obviously a huge challenge, both for German agricultural technology and for the agricultural technology of any other country in the world. But standing on the shoulders of giants, humans are often able to do more and solve more problems!
