"You want to use the Plant Rapid Growth Circle?" Gwen stood up from her seat and looked at Li Wei'er with a frown, "If the plant grows quickly, it will quickly exhaust the earth's strength and cannot be replenished, and eventually cause the plant to die, you know?"

Although it was you, Gwen's eyes were staring at Li Weier tightly, her eyes were serious, even a little stern, perhaps she felt that Li Weier had forgotten such a simple common sense and felt a little angry.

Being looked at by Gwen so seriously, Li Weier was a little flustered, but quickly calmed down and organized her language a little.

She said: "Jiayi invented a soilless cultivation technology, using nutrient solution instead of soil to cultivate plants, only need to replenish the nutrient solution in time, so you don't have to worry about the soil fertility can't keep up." ”

"Nutrient solution?" Gwen wondered what the word literally meant, but she couldn't understand what it was.

And this thing is obviously a liquid, but some plants don't like waterlogging, and they are easy to die when they are flooded, but when they think of the elven rice that Jiayi and they cultivated, they are a little relieved.

After all, elf rice is also rice, and most of the rice is water-loving and drought-tolerant.

"The nutrient solution is an aqueous solution that is prepared according to the nutrients needed by the plant, instead of the soil to cultivate the plant, so that the roots of the plant can directly contact the nutrient solution to obtain nutrients.

Kaichi stepped forward and began to introduce Gwen to the basis of her soilless cultivation theory, for Gwen, a new magic may not be able to attract her, but a new theory she must have this interest in learning about.

After listening to Jiayi's theory, Gwen couldn't give any advice for a while, after all, she hadn't verified it, but it sounded like the foundation of this theory seemed very tight, and there were no omissions.

Seeing that Gwen was still a little suspicious in her words, Li Weier said: "Professor, why don't you go to our laboratory to take a look, Jiayi's no-picture cultivation effect is not bad, and the cultivated wheat seedlings look very good, well, at least for now, it still looks very good." ”

Jia Yi glanced at Li Weier helplessly, if only there was no last sentence, what does it mean that at least for now, there will be no problems in the future.

Gwen became interested, and regardless of Jia Yi and them skipping class, she said to them: "Let's go, let's go and see what is going on with your soilless cultivation, if it is really feasible, I will take care of the matter of the growth circle." ”

Gwen followed Jiayi and them to Jiayi's laboratory, as soon as they entered the door, Gwen frowned slightly, the laboratory was too messy, and some rows were full, the most conspicuous place was the shelf next to the window, which was green.

Gwen walked in and saw that it was all wheat, and she looked at the roots of the wheat, and saw that there was no dirt in it, but a layer of liquid, and the roots of the wheat floated in it, like a white beard.

She turned her head to look at Jia Yi and the others, and said, "Is this your soilless cultivation?

Jiayi took Gwen to see the vat where the nutrient solution was configured, and then showed her how to prepare the nutrient solution

Gwen looked at Jiayi's operation and said approvingly: "I didn't expect you to invent the no-picture cultivation technique, which is indeed very good." ”

After seeing these wheat seedlings grown with soilless cultivation, Gwen realized the benefits of no-figure cultivation, which can more easily control the demand for climate, water and fertilizer in the process of plant growth, and it is easier to adjust.

In particular, the demand for space for no-picture cultivation is greatly reduced, and with the greenhouse to regulate the temperature, even some magic plants with harsh growing conditions are much easier to cultivate.

Not to mention that soilless cultivation can also cooperate with plant growth circles, and can even greatly reduce the time required for cultivation. However, there is one point, it is inconvenient to cultivate tall plants or plants with developed root systems, and it is not possible to use no-picture cultivation techniques.

Gwen glanced at the nutrient solution that Jia Yi had concocted, and suddenly asked, "Is this nutrient solution also available to the rest of the plants in the field to make them grow better, for example, the medicinal herbs in the medicine field." ”

Jia nodded: "Theoretically, this is true, but you can't water too much at a time, and the concentration of the solution can't be blamed for being too strong, otherwise the seedlings will be burned." ”

This is actually a chemical fertilizer, but it is a more primitive chemical fertilizer.

However, Gwen's idea of increasing the growth of medicinal herbs, although theoretically feasible, but the medicinal properties of medicinal herbs are closely related to the growth period, the cycle of the four seasons, and the magical elements absorbed during the growth process, which cannot be achieved through fertilization and accelerated growth, even if it can make the medicinal herbs grow more full and robust, but it cannot enhance the medicinal properties of many medicinal herbs.

But this is not without use, although it cannot enhance the medicinal properties of the herbs, but strong plants are still very good for resisting diseases.

After carefully visiting Jiayi's cultivation without a picture, Gwen said: "Originally, I thought that it would be good if your plant classification could be done well, and I thought that you would fail in the cultivation of elven rice, but now it seems that there is still a good possibility of success."

"Your no-figure cultivation potential is good, you sort it out, write a paper and publish it, all the mages who refine plant cultivation will thank you, perhaps, this can make some of the more precious medicinal materials more popular, and all mages can benefit from it." ”

After speaking, Gwen flipped over her hand, and a small crystal bottle appeared in her hand, which looked very small, but it was only ten or twenty milliliters, and she handed the crystal bottle to Jiayi.

Said: "This is a vitality potion, specially configured for the growth of plants, containing strong vitality, or the use of the elf island of the moon spring water configuration, you before planting elf rice, drop a drop in the water, put the seeds into the soak, can increase the germination rate of seeds, should be helpful for you to plant elf rice." ”

"Thank you, teacher. Jia Yi hurriedly took this vitality potion, or to be precise, the plant vitality potion, listening to the abbreviated name, it sounded like it was for people to drink.

For anything that can increase the chance of success in the cultivation of elf rice, Jia Yi will not let it go, especially when he hears that it contains elf spring water, and it is produced on the same elf island as elf rice, maybe there will be some surprises when it is matched.

Gwen came here, and it can be regarded as checking the progress of Jiayi's work, and Gwen can be said to be very satisfied with the current results.

It's just that after sending the vitality potion, she felt a little distressed again, and hurriedly said, "I'll go to Orlando and see the plant growth circle you need to design, you guys hurry up and go to class." ”

With that, she turned around and walked out the door.

At this time, she thought that Jia Yi and they should go to class, but it was not early, and it looked like it was almost the end of class, and the day's classes were about to end.
