"The carbon-nitrogen ratio is two things, as long as you judge which one is good or worse, you can make up for it in time."

Ma Tianzao nodded seriously when he listened.

Lu Miao thought for a while, and then added: "Every time you add new ingredients, you have to stir them as evenly as possible. ”

Ma Tianzao said "uh-huh" twice and nodded seriously.

Gu Ying held the letter paper and looked over.

"Lu Miao, are your chemistry grades very good?"

Lu Miao shook her head, "No, I just know some things that are relatively simple in daily life." ”

She went to school as a liberal arts student, chemistry and stuff, and she really only knew about the skin.

The chemical reaction of Berkeley composting is mainly the interaction of water, carbon dioxide and oxygen.

At the same time, the reaction creates an environment for microbial growth in the compost, which encourages aerobic microorganisms to multiply and decompose the material.

Nothing else.

The smaller the compost, the more unstable it is.

The compost body is large to a certain extent, even if it is not successful in the early stage, make up for it in the later stage, and almost create a good growth environment for the itchy creatures, no matter what you throw into it later, it can quickly decompose and rot.

When Lu Miao first listened to this open class, the tutor explained it from a distance.

If you throw something like a pineapple into it in the later stage, you don't even need to cut it, and it can be completely decomposed into fertilizer in two or three days.

This is 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 fertilizer is generally soluble in water, and it is easy to carbonize and agglomerate after being damp or wet, which seriously affects the fertilizer efficiency.

There are certain requirements for storage, and if it is exposed to the wind or sun or rain, it will lose its fertilizer effect.

Take the present as an example, in fact, the best thing is to ferment the fertilizer well in winter, plough in spring and spring, and use it directly.

These are all things that came to mind temporarily, not on the letterhead, Lu Miao told Gu Ying and them alone.

Farm fertilizer is linked to agricultural crops in a straight line, Lu Miao is usually not good at work, but at this time, it is analyzed in a set of sets, Gu Ying and others feel very strange.

Lu Miao also responded to this.

For example, the theoretical knowledge I read in the book was not sure at first, but after experimentation, I thought it was feasible, so I took the big guys to do it together.

There is no other excuse for interpretation.

Everyone thought about it and believed it.

Gu Ying estimated that Lu Miao should be the one with the highest level of Chinese among them.

Ma Tianzao stood aside and looked at the group of female intellectuals, and she was so envious.

Ma Tianzao had an idea in his heart, can he read or read more, and see how powerful other people's educated youth are?

I know a lot of words, and I know a lot of truth.

Unlike her, she can only listen awkwardly when she squats on the side.

This batch of manure was piled up on November 4th, unless the day coincided with the light snow of the solar term.

The weather was getting colder and colder, and after the composting was successful, Lu Miao took Gu Ying and a few of them to spread a thick layer of dry straw on the compost pile to cover up.

After that, I waited for He Hongjin to take time out to come and test the results.

The stove in the small kitchen was often burning, and Lu Miao gradually didn't like to go out and walk around.

Chen Guifen came over occasionally, first bringing her a vest and cotton jacket that had been filled with cotton, and then bringing her autumn clothes and pants made of cashmere.

At this stage, it is too exaggerated to wear a padded jacket, so Lu Miao wears autumn clothes and pants inside.

I don't know how much softer and warmer the material of cashmere is much softer and warmer than the gowns and pants like thin sheets.

Lu Miao felt good dressed, and asked Fu Jingyou to turn on the light before going to bed at night, and she took out the money and counted twenty yuan neatly.

"The material of cashmere is five and five feet a piece, and I can still have a little left after I make a set of six feet, if you do it, it should be just right."

She handed the money to Fu Jingyou:

"Tomorrow you make a trip to see if you haven't already, and if you do, buy some more."

Lu Miao also had some tickets in her hand, and she usually went to buy things by Fu Jingyou, so she simply took them out.

Count out all the cloth votes first, and there are nine feet in total.

After that, I counted out some expiring tickets, such as oil tickets, snack tickets, and milk powder tickets.

After picking and counting, in addition to the cloth ticket and the expiring ticket, there are only a few tickets left that can be left in the hand to continue to save.

"This is a cloth ticket, and there is a nine-foot cloth ticket. This is the ticket that is about to expire, and this is a miscellaneous matter. ”

The three piles of tickets that Lu Miao sorted out were pushed to Fu Jingyou together:

"If you still have a cloth ticket there, take it out together, make a twelve-foot one, and let your aunt make you an autumn coat while it's not busy yet."

Lu Miao thought that the twelve-foot cashmere fabric would cost eighteen yuan, and the remaining two yuan would definitely not be enough to spend.

She counted the money, and from the colorful tickets, she drew another twenty scattered pieces.

"Take this one together and use those expiring tickets."

"I can't wear cashmere, I think the kind of green grid I bought for you earlier is very good."

Fu Jingyou honestly accepted the money ticket, but shook his head and said:

"With the money to buy cashmere fabrics, I can make several clothes like that...... I'll buy you another six feet and come back, and let my aunt make you a set of replacements, and I'll buy other materials for the rest, and then ask the old men in the town to see if I can get cotton." ”

"If I could, I might as well make a jacket, you say?"

She said?

She's a ghost!

Lu Miao glanced at him, "The boar can't eat fine bran, so you can't use good things, right?" ”

Fu Jingyou smiled and nodded calmly:

"Yes."

A piece of cashmere fabric is five feet long, which is enough to buy two catties of pork on the meat shop.

Fu Jingyou was willing to give Lu Miao flowers to use this money on himself, but he was reluctant.

Lu Miao was so angry that she fell back.

Could she not have known his thoughts?

Where you can't wear anything, you just can't afford to pay for it.

"I'm too lazy to care about you!"

"I'm coming with you this year, obviously I'm preparing."

Fu Jingyou sat on the edge of the bed and hugged her and coaxed her.

"You spent the winter in the south in the first year, you may not be able to adapt, you should be more prepared, I grew up here since I was a child, and I have long adapted to it."

Lu Miao pouted very unhappily.

"Aren't you afraid of the cold when you get used to it? Not afraid of freezing? ”

"It's hot when I work, and it's not the same now as before, I warm the bed with you at night, where is it cold?"

Fu Jingyou tried to jokingly take over the topic.

Lu Miao glared at him with a snort and pinched him several times on the waist.

Fu Jingyou obediently let her pinch her, but she felt even more angry, lying on his shoulder and biting hard before gradually quieting down.

"Then don't buy cashmere fabrics, you buy more cotton cloth and come back, and then look at getting some cotton, there must be a cotton jacket for winter."

Lu Miao knew Fu Jingyou's thoughts and insistence, and after making a fuss for a while, she put her hands around his neck and obediently compromised her face to his shoulder:

"It's not just this year, it's going to be worn next year, don't be reluctant to ......"
