A day at Hogwarts

Charles has too many things to do, such as planting Chinese kale, drawing a potion configuration process for potions class, discussing with the horsemen to kill a batch of acromantulas after the spring, Dumbledore's book list should be Look, the normal class... I'm so busy at the end of the day.

Professor Sprout is as busy as Charles. The training and competition of the potion championship team requires a lot of herbs, most of which are provided by the greenhouse, and they are not free until the first Saturday morning in February. Come over to Greenhouse 2 to see how the Chinese biting kale is doing.

Charles is fertilizing Chinese cabbage bites in Greenhouse No. 2. Professor Sprout is carefully studying the contents on a stack of A4 papers, and the laughter of students can be faintly heard in the distance.

Charles sent the soil samples in the flower pots to test the content of various nutrients every three days, and displayed the results during this period on the chart, and soon found the problem.

After reading the table, Professor Sprout said to Charles: "Can I understand that Chinese biting cabbage absorbs nutrients in the soil quickly, and as long as the supply of Muggle fertilizer can be maintained, they can grow bigger. "

Charles replied: "I speculate that this is also the conclusion. I used several pots of cabbage for comparison, and the cabbage without Muggle fertilizer is indeed smaller."

Professor Sprout nodded. Now the brightly colored cabbage leaves in the pots have spread out to the surroundings and have begun to enter the balling stage. Compared with the two pots of cabbage leaves without Muggle fertilizer in the control group, the leaves are much smaller , is also thinner.

Charles walked over to the control group, asked Professor Sprout to come over, and pointed to two pots of cabbage.

There is a sign in the soil of these two pots of cabbage, which says "2". The leaves are much larger than the two pots of No. 1 brand without Muggle fertilizer, but smaller than the other pots that were fertilized according to Charles' idea.

The lower ring of leaves of Chinese biting cabbage can be used as legs. It can run and jump, and now it moves when touched.

Charles touched several kinds of Chinese biting cabbage planted in different ways with his hand wearing a dragon leather glove. The two weak ones in pot No. 2 were more vigorous than those in No. 1 pot without Muggle fertilizer, while the others were more Energetic.

Professor Sprout pointed to the cabbage in the No. 2 pot and asked, "Are these two plants not fertilized enough?"

Charles nodded and replied: "Yes, the amount of dragon dung compost on No. 2 is the same as that of No. 1. I have increased the amount of others."

"I speculate that although the size of No. 2 is larger, there is relatively less magic fertilizer, which leads to its low concentration of magic power, so it does not have enough strength."

"Although the size of No. 1 is small, the magic fertilizer is relatively sufficient, and the concentration of magic power contained in it is normal, so the strength is stronger."

Then he pointed to the No. 3 pot of cabbage that looked indistinguishable from the others and said: "These two pots were the same as No. 2 at the beginning. I added more dragon dung compost and moon-crazy manure at noon, and they were already alive at night." Perfect."

"So I added magic fertilizer to the other kale, and they came alive very quickly."

"From the current results, the magic fertilizer can promote the vitality of Chinese biting cabbage, allowing them to absorb more Muggle fertilizers. From the detection point of view, the Muggle fertilizers in the soil decreased rapidly during that period."

"Then I added Muggle fertilizers. With more fertilizers, the kale will grow faster and absorb more magic fertilizers."

"It can be seen that the two fertilizers complement each other and can promote the absorption of the other fertilizer and accelerate plant growth."

After listening to it, Professor Sprout did not draw conclusions lightly, but said with satisfaction: "This is a good discovery. I suggest you continue your research and publish the paper on "Flower Hat."

Charles took off his gloves, scratched his head a little embarrassedly, and laughed.

"Flower Hat" looks like the name of a fashion magazine, but it is the most authoritative academic journal in the field of herbalism in the UK. It was founded 70 years ago by Professor Garrick, who was then a professor of herbalism at Hogwarts. There are in the hall.

Charles has seen Professor Garrick's oil painting in Professor Sprout's office, and the hat on her head has a circle of bright flowers, which is very conspicuous.

But what is more eye-catching is Professor Garrick's appearance. Among the professors in Hogwarts history, he is definitely at the T0 level.

Then Professor Sputrow said to Charles: "It's just that many stubborn wizards are very disgusted with the use of Muggle wizards, so I suggest you use a pseudonym to submit articles."

Charles nodded and agreed, he would naturally be careful about this kind of thing.

Professor Sprout sighed helplessly again, why didn't such a talented student of herbal medicine come from Hufflepuff College? If he couldn't beat Minerva, he would have started poaching him a long time ago.

Charles asked the professor for a soil test chart, found one of them and asked, "Professor, I found that the calcium and phosphorus in the soil suddenly decreased. Is it because the cabbage has started to grow teeth?"

Professor Sprout asked with a smile: "Can you tell me what they do?"

She doesn't know much about the research results of Muggles, but she won't pretend to understand, and she will ask what she doesn't know.

Charles began to explain: "According to Muggle research, the main component of our teeth is calcium phosphate..."

Chinese biting cabbage has "bite" in its name, indicating that they have teeth, and it is not surprising that they have animal teeth.

After hearing this, Professor Sprout replied: "It's okay to use teeth to understand the hard thorns on the leaves of Chinese gnawing cabbage. Then they will enter the ball stage and start to grow teeth."

"Next, we need to add some dried eggshell powder to the soil. If you have better fertilizer, you can try it."

Charles is not very familiar with fertilizers other than nitrogen, phosphorus and potassium, so he could only write a letter back and ask the old man to ask the experts.

After finishing today's work, Sprout said to Charles: "If you go to the horseman recently, you can take the branches of the flowers that were planted last year and reproduce them. Now they are planted in seedling pots, waiting for you to come back from Moon Mountain. It can be transplanted into the ground."

Charles immediately said happily: "Great, I just plan to go to the horseman's place after lunch."

Professor Sprout turned to look at the two of them in the greenhouse, and said, "Now that the weather is getting warmer, ask me if there is a purple mushroom that is as tall as a finger, I want it myself."

"If you want it back, I can help you within the scope of my authority."

Charles asked curiously, "Can that kind of mushroom be used as a medicinal material?"

Professor Sprout replied: "It's very delicious to put a tree in the stew. This is my secret recipe. Don't tell me!"
