Chapter 171 The old man who loves his wife
"The carbon-nitrogen ratio is two different things. Just judge which one is different and make up for it in time."
Ma Tianzao nodded seriously after hearing this.
Lu Miao thought for a while, and then added: "Every time you add new ingredients, stir them as evenly as possible."
Ma Tianzao said "hmm" twice, seriously nod.
Gu Ying held the letter and looked over.
"Lu Miao, are your chemistry scores very good?"
Lu Miao shook his head, "No, I only know some simple daily things."
She went to school as a liberal arts student, and she really only had a superficial understanding of things like chemistry.
The chemical reaction of Berkeley compost is mainly the interaction of water, carbon dioxide and oxygen.
While the reaction occurs, an environment for microbial growth is created in the compost, which encourages aerobic microorganisms to reproduce and decompose materials.
Nothing else.
The smaller the compost body, the more unstable it is.
When the compost body is large enough, even if it fails in the early stage, you can make amends in the later stage. After creating a good growth environment for the itchy organisms, no matter what you throw into it later, it will be decomposed and decomposed quickly.
When Lu Miao first listened to this open class, the instructor explained it in detail.
For a mature compost volume exceeding one cubic meter, if you throw something like a pineapple into it later, you don't even need to cut it. It can be completely decomposed into fertilizer in two or three days.
This is Good Itch Compost, an organic fertilizer made by fermenting various materials.
It produces fertilizer quickly, but "organic fertilizer" also has a relatively fatal problem.
It is storage.
Organic fertilizers are generally easily soluble in water. When exposed to moisture or water, they are easily carbonized and agglomerated, seriously affecting fertilizer efficiency.
There are certain requirements for storage. If it is left to be exposed to wind, sun or rain, it will lose its fertilizer effect.
Take the current example. In fact, the best thing is to ferment the fertilizer in winter, plow it in spring, and use it directly.
These were all things that came to mind at the last minute and were not on the letter. Lu Miao told Gu Ying and the others alone.
Agricultural fertilizers are directly linked to agricultural crops. Lu Miao is usually not good at work, but now she analyzes them in exactly the same way. Gu Ying and others find it strange.
Lu Miao also responded to this.
For example, I was not sure about the theoretical knowledge I read in books at the beginning. After experiments, I felt it was feasible, and I took everyone together to do it.
Other than this, there is no other excuse that is more suitable as an explanation.
Everyone thought about it and believed it to be true.
Gu Ying estimated that Lu Miao should be the one with the highest level of education among them.
Ma Tianzao stood aside and looked at the female educated youths with envy.
Ma Tianzao had an idea in her mind. If she could study, she should study more to see how good the educated youth were.
I know a lot of words and understand a lot of truths.
Unlike her, she could only listen in embarrassment while squatting on the edge.
This batch of fertilizer is piled starting on November 4th, unless it happens to coincide with the day of light snow in the solar terms.
The weather was getting colder and colder. After the composting was successful, Lu Miao took Gu Ying and the others and spread a thick layer of dry straw on the compost pile as a cover.
After that, I waited for He Hongjin to take some time to come over and check the results.
The stove in the small kitchen was often burning, and Lu Miao gradually stopped going out and walking around.
Chen Guifen came over occasionally and first brought her a vest and cotton-padded jacket filled with cotton, and later gave her autumn clothes made of cashmere material.
Wearing a cotton-padded jacket is too exaggerated at this stage, so Lu Miao wore autumn clothes and long trousers underneath.
I don’t know how much softer and warmer the cashmere material is than the thin sheets of jackets and underwear.
Lu Miao felt well dressed, so she asked Fu Jingyou to light the lamp before going to bed at night. She took out the money and counted out twenty yuan neatly.
"The cashmere material costs one and a half feet. If I make a set of six feet, there is still some left. If you make it, it should be just right."
She handed the money to Fu Jingyou :
"Go over tomorrow and see if there are any. If there are any, buy some more." Lu Miao also has some coupons in her hand. Fu Jingyou usually goes to buy things, so she simply takes them all. came out.
First count all the cloth tickets. There are nine feet in total.
Then I counted out some expiring tickets, including gas tickets, snack tickets, and milk powder tickets.
After picking and counting, except for cloth tickets and ex-dated tickets, there were only a few tickets left that could be kept in my hands.
"These are cloth tickets, there are nine-foot cloth tickets. These are the tickets that are about to expire, and this is other miscellaneous ones."
Three piles of tickets listed by Lu Miao Let’s recommend it to Fu Jingyou:
"If you still have some cloth tickets, take them out together and make a twelve-foot one. Before you are too busy, ask aunt to make autumn clothes for you."
Lu Miao was thinking about twelve feet. Cashmere fabric costs eighteen yuan, and the remaining two yuan is definitely not enough.
She counted the money and took out a scattered twenty yuan from the colorful bills.
“Take this together and use those expiring checks.”
“I can’t wear cashmere material. I think I bought the green checkered one for you earlier. The ingredients are very good.”
Fu Jingyou accepted the money note honestly, but shook his head and said:
“The money I spent on cashmere fabric can make several clothes like that...I’ll buy you another six feet and let my aunt make it for you. A replacement set, I will buy the rest of the materials and ask the dealers in the town to see if they can still get cotton."
"If I can, I might as well make a coat, what do you think?" >
She said?
She is talking nonsense!
Lu Miao rolled her eyes at him, "The wild boar can't eat fine chaff, so you can't use the good stuff, right?"
Fu Jingyou laughed and nodded calmly:
"Yes."
< br>One piece of cashmere fabric costs one foot, which is enough to buy two kilograms of pork at the meat shop.
Fu Jingyou was willing to give this money to Lu Miaohua, but he was reluctant to use it on himself.
Lu Miao fell back in anger.
Would she not know his little thoughts?
What I can’t wear is that I can’t bear to spend money.
“I’m too lazy to care about you!”
“I’ll stick with you this year, and I’ll prepare next year.”
Fu Jingyou sat by the bed and hugged her to coax her.
"You may not be able to adapt to your first winter in the south. You should be more prepared. I grew up here and have long since adapted."
Lu Miao pouted. Mouth is unhappy.
“You’re not afraid of the cold after you’ve adapted to it? Are you not afraid of the cold anymore?”
“It’s warm when you do the work. Besides, it’s different from before. I have you to warm the bed with me at night, so it’s not cold anymore. ”
Fu Jingyou tried to take over the topic jokingly.
Lu Miao glared at him and pinched his waist several times.
Fu Jingyou obediently let her pinch him, but she felt even more angry. She lay on his shoulder and bit him hard before gradually calming down.
"Then don't buy cashmere fabrics. Buy more cotton fabrics, and then we'll get some cotton. We must have cotton-padded jackets for the winter."
Lu Miao knew Fu Jingyou's thoughts and persistence, After making a fuss for a while, she held his neck with both hands and put her face on his shoulder in a compromising manner:
"It's not like I'm just going to wear it this year, I'll wear it next year too, don't be reluctant to part with it..."
