Chapter 171: The Old Master Who Loves His Wife
"Carbon and nitrogen ratios are just two things. You just need to determine which one is better or worse and make up for it in time."
Ma Tianzao listened carefully and nodded.
Lu Miao thought for a moment and added, "Every time you add new ingredients, you must stir them as evenly as possible."
Ma Tianzao said “hmm” twice and nodded seriously.
Gu Ying looked over holding the letter.
"Lu Miao, are your chemistry grades good?"
Lu Miao shook his head. "No, I just know some simple everyday things."
She was a liberal arts student in school, and she only had a superficial understanding of things like chemistry.
The chemical reaction of Berkeley composting is mainly the interaction between water, carbon dioxide and oxygen.
While the reaction is taking place, an environment for microbial growth is created in the compost, promoting the reproduction of aerobic microorganisms and the decomposition of materials.
There's nothing else.
The smaller the compost pile, the less stable it is.
When the compost pile is large enough, even if it is not successful in the early stage, you can make up for it in the later stage. After creating a good growth environment for the itchy organisms, no matter what is thrown into it later, it will be quickly decomposed and fermented.
When Lu Miao first attended this open class, the instructor had explained it in detail.
For a mature compost with a volume of more than one cubic meter, you can throw something like a pineapple into it later without even cutting it. It will be completely decomposed and turned into fertilizer in two or three days.
This is Haoyang compost, an organic fertilizer made by fermenting various materials.
It produces fertilizer quickly, but "organic fertilizer" also has a relatively fatal problem.
It's storage.
Organic fertilizers are generally easily soluble in water. Once damp or wet, they are very likely to carbonize and clump, which seriously affects the fertilizer efficiency.
There are certain requirements for storage. If it is exposed to wind, sun or rain, the fertilizer will lose its effectiveness.
Taking the present as an example, the best thing is to ferment the fertilizer in winter and use it directly when spring plowing begins.
These were things he thought of on the spur of the moment and were not on the letter paper. Lu Miao told them about them separately with Gu Ying and the others.
Agricultural fertilizers are directly linked to farm work and crops. Lu Miao is not good at the work normally, but he can analyze it very well now. Gu Ying and others find it very strange.
Lu Miao also responded to this.
For example, I was not sure about the theoretical knowledge I read in books at the beginning. It was only after trying it out that I felt it was feasible and then I brought everyone to do it together.
Apart from this, there is no other more suitable excuse.
Everyone thought about it and believed it to be true.
Gu Ying estimated that Lu Miao should be the most educated among them.
Ma Tianzao stood aside and looked at the female educated youth, feeling extremely envious.
Ma Tianzao had only one thought in his mind: if he could study, he should study more and see how capable the educated youth were.
The more words you recognize, the more principles you understand.
Unlike her, I could only squat on the side and listen awkwardly.
This batch of fertilizer was piled up on November 4th, unless that day happened to coincide with the day of Xiaoxue, the solar term.
The weather was getting colder. After the composting was successful, Lu Miao took Gu Ying and the others to spread a thick layer of dry straw on the compost pile as a cover.
After that, we just had to wait for He Hongjin to find some free time to come and check the results.
The stove in the small kitchen was always burning, and Lu Miao gradually became less and less interested in going out.
Chen Guifen came over occasionally, first bringing her vests and cotton-padded jackets filled with cotton, and later bringing her autumn clothes made of cashmere.
At this stage, wearing a cotton-padded jacket is too exaggerated, so Lu Miao wears long-sleeved shirts and long trousers inside.
Cashmere material is much softer and warmer than thin coats and clothes.
Lu Miao felt good wearing it, so she asked Fu Jingyou to turn on the light before going to bed at night. She took out the money and counted out twenty yuan neatly.
"Cashmere material costs $1.50 a foot. I can make a six-foot suit and still have some left over. If you make it, it should be just right."
She handed the money to Fu Jingyou:
"Go back tomorrow and see if they still have it. If they do, buy some more."
Lu Miao also had some tickets in her hand. Fu Jingyou usually went shopping, so she simply took them all out.
First count all the cloth coupons, there are a total of nine feet of quota.
Then he counted out some expiring tickets, including oil tickets, snack tickets, and milk powder tickets.
After picking and counting them, I found that there were only a few tickets left that I could keep, except for the cloth coupons and the impending coupons.
"These are cloth coupons. There are nine feet of them. These are the ones that are about to expire, and these are other miscellaneous items."
Lu Miao pushed the three piles of votes he had sorted out to Fu Jingyou:
"If you still have some cloth coupons, take them out and make a twelve-foot long coat. Since it's not busy now, let your aunt make you a coat too."
Lu Miao thought that twelve feet of cashmere fabric would cost eighteen dollars, and the remaining two dollars would definitely not be enough.
She counted the money and took out another twenty yuan from the colorful bills.
"Take this and use up those near-due bills."
"I can't wear cashmere. I think the green plaid material I bought for you earlier is very good."
Fu Jingyou accepted the money honestly, but shook his head and said:
"With the money I spent on the cashmere, I could make several sets of clothes like that... I'll buy you another six feet and have my aunt make you a replacement set. With the rest, I'll buy some other material and ask the traders in town if they can get me some cotton."
"If I could, I might as well make a coat, what do you say?"
She said?
What the hell is she talking about!
Lu Miao rolled his eyes at him and said, "Wild boars can't eat fine bran, so you can't use good things, right?"
Fu Jingyou laughed and nodded calmly:
"yes."
Cashmere fabric costs one dollar and fifty cents per foot, which is enough to buy two kilograms of pork at the meat shop.
Fu Jingyou was willing to give this money to Lu Miao, but he was reluctant to use it on himself.
Lu Miao was so angry that he fell backwards.
Wouldn't she know his little thoughts?
It’s not that I can’t afford it, it’s just that I’m reluctant to spend the money.
"I really don't care about you anymore!"
"You come first this year, and I'll prepare next year."
Fu Jingyou sat beside the bed, holding her and coaxing her gently.
"It's your first winter in the south, so you might not be able to adapt. You should be more prepared. I grew up here and have adapted a long time ago."
Lu Miao pouted and looked unhappy.
"If you adapt, you won't be afraid of the cold? You won't be afraid of the cold anymore?"
"I'll feel warm after working. Besides, things are different now than before. I have you warming the bed with me at night, so how can I be cold?"
Fu Jingyou tried to take over the topic jokingly.
Lu Miao snorted and glared at him, then pinched his waist several times.
Fu Jingyou obediently let her pinch him, but she felt even angrier. She leaned over his shoulder and bit him hard again before she gradually calmed down.
"Then don't buy cashmere fabric. Buy some cotton cloth and then find some cotton. You definitely need a cotton-padded jacket for winter."
Lu Miao knew Fu Jingyou's thoughts and persistence. After a while of making a fuss, she put her arms around his neck and put her face against his shoulder in obedient compromise:
"You're not just going to wear it this year. You'll still wear it next year. Don't be so reluctant..."
