Vol 3 Chapter 2120: 1 tree produces 4 tons of watermelon per year

"We have inserted some vine plant genes into the watermelon gene sequence, so that its vines and roots are lignified. On the one hand, of course, this is to make the vines stronger and able to withstand heavier weights. On the other hand, On the other hand, it also prolongs the lifespan of the melon vine and changes the growth habit of the melon vine from annual to perennial.

This can change some of the watermelon's planting habits, allowing it to be managed like a fruit tree and continue to grow for many years. As for ordinary watermelon varieties, it takes a year to plant a new place, and we don't need to change the place to plant.

In addition, we also optimized the size of the watermelon, including the taste and taste. Because it is a hanging melon, the size of the watermelon should not be too large. The overall size is about 20 cm, and it is round.

The skin is golden or green, and the skin is thin but firm and not easily broken. That's what we've made specifically to improve. The purpose is to prevent the watermelon from being broken during transportation and avoid unnecessary losses and waste.

Melon pulp belongs to the kind of sand pulp with sufficient water content, and the sugar content of mature watermelons can reach more than 20 degrees, which is already very sweet among watermelon varieties. And we have also carried out seedless improvement, so that this watermelon has no watermelon seeds and is very convenient to eat. "

"Without seeds, how does this watermelon breed?" Zhang Jun couldn't help but wonder.

"Hehe, this involves the application of Fangmu's technology to artificially induce polyploidy. In fact, seedless watermelons are also grown from watermelon seeds, but seedless watermelons are triploids because of triploids. When cells undergo meiosis, synapses are disordered, so triploid watermelons cannot form seeds.

However, we can also use this technology to breed tetraploid watermelons and diploid watermelons. Every year, the tetraploid watermelon is the female parent and the diploid watermelon is the male parent.

Of course, there is a more convenient method, that is, the grafting method and the cutting method. The grafting technology is used to cut some young shoots and branches from the mother tree for cutting cultivation, or grafting for breeding. "

Seeing everyone nod, Yang Fang also led the crowd to introduce them as they walked. These are some fruits and vegetables, using the same technique as this watermelon tree. The biggest advantage of this is that the output is huge and it is easy to manage.

Like the watermelon tree above, a tree can grow four tons of watermelon a year, that is, 8,000 catties of watermelon, which is a very scary number (Note 1), and the yield of other melon and fruit trees is not bad. All around this figure, it can be said that the output is very amazing.

This also makes Wu Hao full of interest in this technology. Their biggest project at present is the lunar scientific research station preparation project. In the future, in order to allow astronauts, scientists and some resident tourists to live longer on the moon, it is necessary to adapt to local conditions and become self-reliant.

Therefore, it is also an inevitable trend to establish a lunar plant factory to grow and cultivate related agricultural products, fruits and vegetables. After all, it is only supplied from the moon. On the one hand, it is difficult to provide such long-term fresh vegetables and fruits to meet the dietary needs of the crew in the scientific research station. On the other hand, it is difficult to completely control the cost of this kind of earth-moon supply, even using Wu Hao's step-by-step transport technology.

Therefore, a lunar plant factory is bound to be established. What can be planted in this plant factory needs to be carefully studied and considered.

And these melon and fruit trees have huge output and are easy to manage. If they can be planted in the lunar plant factory, it will provide a very abundant and stable source of melons, fruits and vegetables for the lunar scientific research station.

Thinking of this, Wu Hao immediately asked Yang Fang.

After hearing his question, Yang Fang smiled and shook his head: "At present, we are not quite sure that this variety of vegetables, melons and fruits is suitable for growing in the lunar environment. Because this kind of vegetables, melons and fruit trees has a huge yield, it is very important for fertilizer nutrients. The demand is also huge.

The Moon is very barren, and it remains to be seen whether these varieties are suitable for growing. "

Hearing Yang Fang's answer, Wu Hao was not disappointed, but nodded and said to her: "In this way, based on this aspect, you can communicate with the lunar scientific research station project team of the aerospace department and see Can we cooperate on this.

I very much hope that these new technologies can also be applied to the construction and operation of lunar scientific research stations. In the future, we will survive in space and extraterrestrial planets for a long time, and food is a problem that we must solve. Close to the earth to supply, the efficiency is too low, and the cost is too high. And the delivery time is too long, even if it is produced by advanced refrigeration, it is difficult to store a large amount of fresh vegetable ingredients.

Therefore, the best way is to be self-sufficient, and grow it by yourself in space, on the moon, and even on Mars in the future, and even on some other planets. "

Everyone nodded when they heard his words, and Yang Fang responded with a smile: "You can rest assured that our cooperation with the aerospace department has continued. At present, our main research is assured that the circular construction of the space farm ecosystem is researched.

We have verified through the Oasis inflatable inflatable space experiment module that we can build a space farm and a simple space ecosystem, but whether this ecosystem really meets our needs, we still can't be sure in this regard.

Because this ecosystem is still very rudimentary and relatively fragile, and it is not acceptable to everyone~www.readwn.com~ For example, in our cultivation of mealworms, although it is a very good source of high-quality protein, it is not for everyone. If you can accept eating this kind of worm, and eat it every day, the taste is definitely not very good.

Therefore, we are currently researching to introduce some other animals in the entire ecosystem, so as to make the entire ecosystem more complete and provide astronauts with better and higher-quality meat and protein.

For example, our scientists have proposed to add bullfrogs and rabbits to it. Rabbits can be raised on forage plants, which are a very good source of meat. As for the bullfrog, it is the same. It grows up by eating mealworms, and the meat quality is also very good. Both of them grow and reproduce very quickly and do not need to take up too much space, making them very suitable for space breeding.

And like bullfrogs, we can transport some refrigerated fertilized eggs to the field for cultivation, which is more convenient to transport. Unlike mammals like rabbits, we need to transport live rabbits from Earth to breed. "

[Note, this figure refers to the tomato tree displayed at the West Farm Expo, which can grow 6,000 catties of tomatoes every year. Based on this, I made a reasonable imagination. 】12075/10529662
