"The carbon-nitrogen ratio is just two things. You just need to judge which one is worse and make up for it in time."
Ma Tianzao nodded seriously.
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 and nodded seriously.
Gu Ying held the letter and looked over.
"Lu Miao, are your chemistry scores good?"
Lu Miao shook his head, "No, I just understand 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, the more unstable it is.
When the compost is large enough, even if it fails in the early stage, it can be replenished 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 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 Itchy 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. 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 he analyzes them in exactly the same way. Gu Ying and others find it strange.
Lu Miao also responded to this.
For example, I wasn't sure about the theoretical knowledge I read in books at first. After experiments, I felt it was feasible, so I took everyone to do it together.
Apart from 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.
He knows many words and understands many principles.
Unlike her, she could only listen in embarrassment while squatting on the edge.
This batch of fertilizer was piled on November 4th, unless it happened to be the day of light snow during 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 always burning, and Lu Miao gradually didn't like to go out and move around.
Chen Guifen came over occasionally and first brought her a vest and cotton-padded jacket filled with cotton, and then gave her autumn clothes made of cashmere material.
At this stage, wearing a cotton-padded jacket was too exaggerated, 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 and asked Fu Jingyou to turn on the lamp before going to bed at night. She took out the money and counted out twenty yuan neatly.
"The cashmere material is one piece for five 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, buy some more."
Lu Miao also had some coupons in her hand. Fu Jingyou usually went to buy things, so she simply took them out.
First count all the cloth tickets. There are nine feet in total.
Then I counted out some expiring coupons, including gas coupons, snack coupons, and milk powder coupons.
After picking and counting, I found that apart from cloth tickets and expiry tickets, there were not many tickets left that I could keep in my hands.
"These are cloth tickets. There are nine-foot cloth tickets. These are the tickets that are due soon. This one is a miscellaneous one."
Lu Miao divided the three piles of votes and pushed them to Fu Jingyou:
"If you still have some cloth tickets, take them out together and make a twelve-foot-long one. While you're not busy now, let Auntie make you some autumn clothes."
Lu Miao thought that twelve feet of cashmere fabric would cost eighteen yuan, and the remaining two yuan would definitely not be enough.
She counted the money and took out a scattered twenty yuan from the colorful bills.
"Take this together and use those expiring bills."
"I can't wear cashmere material. I think the green checkered material I bought for you earlier is fine."
Fu Jingyou accepted the money ticket 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 ask my aunt to make a replacement set for you. I'll buy the rest from other materials and ask the town Those bad guys, let’s see if they can still get some cotton.”
"If I can, I might as well make a coat, what do you think?"
she says?
What the hell is she talking about?
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."
A piece of cashmere fabric costs 51 feet, which is enough to buy two kilograms of pork at the meat shop.
Fu Jingyou was willing to give this money to Lu Miao and use it on himself, but he was reluctant to part with it.
Lu Miao fell back in anger.
Could 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 first this year. Obviously I'm preparing."
Fu Jingyou sat by the bed and hugged her to coax her.
"You may not be able to adapt to the winter in the south the first year. You should be more prepared. I grew up here and have already adapted."
Lu Miao pouted and was unhappy.
"You're not afraid of the cold now that you've adapted to it? Are you not afraid of the cold anymore?"
"It's warm just by doing the work. Besides, it's different now than before. I have you warming up the bed with me at night. Why is it so cold?"
Fu Jingyou tried to take over the topic jokingly.
Lu Miao snorted and glared at him, pinching 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 I'll look at getting some cotton. I'm sure I'll have a cotton-padded jacket for winter."
Lu Miao knew Fu Jingyou's thoughts and persistence. After making a fuss for a while, she put her arms around his neck and compromisingly put her face on his shoulder:
"It's not just for this year, but also for next year. Don't be reluctant to part with it..."
