Everyone followed the teacher into a garden with a pond, and Teacher Runqing opened the classroom channel of the liaison and began to explain it eloquently. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

"Our farms are not simply raising and sowing seeds, but have their own imitation ecosystem." She paused slightly, and just as she wanted to continue, a student asked a question.

Runqing gave the student the right to speak, and a bright boy sounded in the channel: "Ask the teacher, what is an imitation ecosystem?" ”

"Imitation ecosystem is to establish a simulation system based on the original living environment of alien beasts and plants. Including elemental energy, water, soil, light, temperature, humidity, dependent biological and microbial reactions, system operation laws and many other aspects. After praising the students who asked the questions, Teacher Runqing explained gently.

"It's just that, due to the complexity of the elemental energy, the imitation ecosystem is very limited. For example, at present, only monophyletic element imitation ecosystems can be established. Or use the native environment to establish an ecological farming system for the native planet. She shook her head with a little regret.

"Teacher, I heard that the breeding garden can only cultivate low-level materials, right?" Another student took the floor to ask questions.

"Of course not. Some primary materials can also grow into intermediate materials as long as they have sufficient energy. Runqing smiled slightly, the students in this class are very active.

"Low-grade materials are cultivated because they have a short growth period, are less dangerous, and the consumption and output can be in line with economic value, while allowing more children to receive adequate nutrition. Generally, the farm will be divided into three or seven, that is, 70% of the low-grade materials, and 30% of the remaining materials will continue to grow to the medium-grade materials. However, high-grade materials cannot be cultivated on a large scale. ”

Runqing looked at the time and ended the topic, "Okay, now I'll let your assistant head take you around." If you have any questions, you can ask them, and if you can't answer them, I will focus on explaining. ”

The four assistant teachers led their teams to practice separately. The teaching assistant of Dor's group is a lively and cheerful senior sister who speaks humorously and interestingly, and is very popular with new students.

She took everyone to the pond and asked the robot at the water's edge to dig up a complete water lotus for everyone to see. "You see, the alien plants in the water are water lotus, which is a species of ancient earth. Its roots are in the underwater silt, and it bears fruit after flowering. Guess where our food is? ”

"I'll take the test!" A student took out a detection instrument and was about to insert a probe.

"Huh! I said it was a guess, are you going to cheat? The senior sister looked at him with wide eyes and asked, and everyone laughed good-naturedly.

"Definitely not the root!" A girl said with disgust as she looked at the muddy clump of roots.

"It's certainly not a seed." A boy also comically learned from the girl just now that all the fruits that can be eaten these days are the flesh.

Duo'er laughed out loud, and the assistant sister glared at her, "What are you laughing at, guess!" ”

"The two of them said they couldn't eat the ingredients." Duo'er smiled, if this is really an ancient earth species, they have already collected it in Lefeng Star, and the food is still roots and lotus seeds.

The TA laughed too, "Looks like you know this." What this heterogeneous plant can eat are roots and lotus seeds. After speaking, she put a ball of mud into the pond and washed it, revealing the white and tender lotus root inside, took the first classmate's testing instrument for testing, and showed the data to everyone.

Then, the teaching assistant showed them several kinds of fish in the pond that live on water lotus leaves, as well as shrimp and crabs, water frogs hiding under lotus leaves, other aquatic plants by the pond, water birds, and water fruit trees on the shore.

There are about 80 species of organisms in this ecosystem, which produce more than 100 kinds of ingredients.

Duo'er wondered in her heart, "Senior sister, why can't you concentrate on planting one or several different plants, and you must use the method of ecological garden?" ”

"Alien plants and alien beasts are also wise! They all have their own territory, and no matter how many seeds you scatter and how many young animals you put in, there is still only so much survival in the survival of the fittest. Therefore, the establishment of a food chain and the cultivation of more varieties can make more profits. The assistant teacher told her very responsibly.

"However, if the alien beast wants to eat the alien plant, the yield of the alien plant will be less." Duo'er was still confused, although she was a cook, she didn't know anything about how to farm.

"Huh! For example, for example, the water lotus, which can only grow 100 seeds in this pond, raises fish, and they eat the leaves and flowers of the water lotus, which does not affect the harvest of the water lotus. But we have more fish to catch. ”

As soon as she said this, Duo'er understood that the creatures in the breeding system are dependent, not natural enemies.

The students also looked at the elemental energy system of the ecological breeding garden, which is to use instruments to slowly release the energy of elemental crystals at several equally spaced locations in the garden.

"When the ingredients reach the energy level, they can be picked. The ingredients we pick are not the ones we buy at the mall, and they need to be sorted and processed. "The assistant teacher took everyone into the underground of the farm, which is a food processing plant, and all the robots are working.

Everyone visited one by one according to the order of food processing, and listened to the introduction of the teaching assistant: "First, tidy up and cut the edible parts; Then detect and sort, and grade according to the energy level; Secondly, clean the labeled packaging, which becomes a saleable ingredient. ”

"Do you know what kind of ingredients are best?" Finally, the assistant teacher asked everyone a question.

"The purest energy!" The students replied in unison that this was an important idea that they had been instilled in the past few days.

"You're right." The teaching assistant laughed, "The freshness of the freshly picked food has a good taste and full of energy; Not to mention the deterioration of the taste after a long time, there is still a loss of energy, even if it is stored in the crisper box, there is a change, but it is much slower. ”

"The energy of alien plants and alien beasts is the same as that cultivated by humans. The primary level is the energy that has just been promoted, which is unstable and needs to be precipitated for a while. The energy of the higher level is like that of a human being when facing a breakthrough, and it is the purest. ”

"Heterogeneous plants of the same level, with strong vitality, absorb energy well, and have better energy purity. Alien beasts of the same level, strong ones have better energy purity. ”

Duo'er listened to it with relish, but she didn't expect so many ways to choose ingredients.

The afternoon tour ended quickly, and in the evening, Duo'er still had to go to the Combat Academy to take a basic mecha training class.

She connected Yang Shengtong's video on the flying car: "Xiaotong, I have to do mecha training at night, so I won't go back, I will go to Wuweifang for dinner." ”

"Got it. How about a few guys who are bothering you? Yang Shengtong was sweating profusely and lying on the floor of the practice room, his voice still carrying the wheezing after intense exercise.

"It's still the same, always probing the brain with bad intentions, but I'm not making any small moves." When it comes to the trouble that makes Duo'er upset, she is a little depressed, and she is not afraid of thieves stealing, but she is afraid of thieves, what is going on? Psychological warfare?

"I found someone to check them, but I didn't find any connection between them and Yu Huanjiao and Song Qingtao. But they applied to join the Mingxuan group during this time, and they had more contact with the people there. Yang Shengtong's words were vague and seemed to be meaningful. (To be continued.) )
