"What are you doing here?"

Although he was wearing a raincoat and a gas mask, Lei Ming Han Xiaolei still recognized Lu Yuan who was squatting next to those big basins for the first time, and walked over and asked. Ran Wen ???? ?? ? ?ｅｎ`ｏｒｇ

"Do experiments, or whatever!"

Lu Yuan happily looked at those big pots and said, "Do you see the soil and crops here?" We took samples from the fields in each area of Muma County, and then applied ammonia fertilizer to see how it grew, after all, the soil quality is different, and the types of fertilizer needed are also different, and in some places ammonia fertilizer is to increase nutrients, and in some places it is equivalent to poisoning......

These words, listening to the thunder Han Xiaolei one by one, said that they could still catch up in the war, saying this, they were like listening to a book from heaven.

"Hey, I'm confused, talking to you two old people about botany......"

Lu Yuan patted his head when he looked at the appearance of the two, and he was a little disappointed that the cow played the piano and the cow chewed the peony.

"What are you proud of? What, what, what, biology, is it amazing? Can you eat it? ”

Lei Ming Han Xiaolei suddenly crooked his nose when he heard this, a kind of shame of being despised, and a kind of annoyance of being shown off in front of him.

"Hey, don't say it, you can eat it!" Lu Yuan said with a smile.

"This is the ammonia fertilizer I make from the ammonia extracted from the exhaust gas of the steel mill and the coking coal plant!"

An Leping, a doctor of chemical engineering, explained with a smile: "Botany, a developed country in Europe and the United States, has long been studied, and the help of various trace elements to plant growth has also been determined, but it is still in the exploration stage, and the research equipment in all aspects is not perfect, and of course we don't have it in Trojan County now, so we can only follow the meaning of the head of the road, use soil methods, and carry out sampling experiments little by little, and strive to experiment that the soil quality in those places in the county is suitable for applying ammonia fertilizer, how much dosage is needed, and so on......."

"Does it work?"

Hearing this, Lei Ming and Han Xiaolei became excited, now is the most difficult stage in the base area, although it has not yet reached the level of starvation, but almost everyone is full of vegetables.

If this ammonia fertilizer experiment is successful and greatly increases the grain yield, it will be of great significance to the base area!

"Of course it works, you see!"

Lu Yuan proudly pointed to the seedlings in those big pots and said: "Did you find that the seedlings in these dozen pots, the growth of the grain is obviously better than that in other pots?" ”

The seedlings in those pots, the seedlings in the grain, are obviously several times better than the next few pots, and it is conceivable that if this growth can be maintained, the yield will definitely increase a lot in the future!

"Lu Yuan, you kid can do it!"

Han Xiaolei excitedly punched Lu Yuan and said: "Not only can you fight, but you can also improve guns, make penicillin, and now make fertilizer, even you know what gringos don't understand, is there anything you can't do?" ”

"I just provide a research direction, but the specific grasp is completed by Dr. An, if I want to be myself, I can only talk on paper, I can't figure it out at all......"

Lu Yuan said modestly, but the smug look was almost like it was about to overflow from behind the gas mask.

"Commander, you can't say that!"

An Le hurriedly waved his hand and said: "Although the specific operation is what I did, but if there is no research direction for you, I will break my head, and I will never think that the ammonia extracted from the exhaust gas can be made into fertilizer, and at the same time increase the production of food To be honest, when I see you, I feel that I have studied and studied chemical industry for so many years, and I have lived to ...... dogs."

"Dr. An, I can't afford to say that......"

Lu Yuan smiled dryly, and said in his heart that you are really capable, and I just occupy the height of the times, and I have nothing to show for it.

"Doctor, don't praise him, you have to praise him again, I think his tail is going to rise to the sky!"

Lei Ming glanced at Lu Yuan stupidly, and then said: "Let's talk first, this fertilizer can't be divided like the things produced by the steel factory and arsenal, and the matter of making money is on the sidelines, first of all, we must ensure that we supply ourselves, this is a question related to whether the people and soldiers in our base area can eat!" ”

"I don't need you to teach me this kind of thing!"

Lu Yuan nodded and said: "Over there, you will also sample the soil in the field, and first make sure that the field is indeed suitable for ammonia fertilizer, as I said, this fertilizer is good to use it is a rain from the sky, and the yield and income will increase, but if you don't use it well, it will be poison!" ”

"You don't need to say it, it's about millions of mouths to eat, who dares to mess around?"

Lei Ming, Han Xiaolei, and Liu Minghui nodded again and again, and then asked carefully: "If you use this fertilizer well, will the production capacity per mu reach two hundred and fifty catties?" ”

"Two hundred and fifty pounds? Is that all you have to offer? ”

Lu Yuan glanced at the three of them and said: "This fertilizer is a product of science, and it only increases the income of one mu and dozens of catties?" At the very least, you have to produce more than 300 catties per mu! ”

"Isn't that more than the yield per acre?"

Hearing this, the three of Lei Ming trembled with excitement and screamed: "Isn't that a few years later, we will have rice and white noodles to eat every day?" ”

"The head of the regiment is a conservative estimate, if my calculation is correct, I dare not say that the production capacity per mu cannot exceed 500 catties, but it is not a big problem to exceed 400 catties!" An Leping threw a bombshell again.

"Four hundred pounds? Oh my God......"

Hearing this answer, Lei Ming, Han Xiaolei, and Liu Minghui looked happy, exaggerated as if they were about to faint.

At the time of the summer harvest, the yield per mu in Mulma County reached about 200 catties, and the yield was unbearable.

But in fact, the yield per mu in Trojan County is already considered high, and the yield per mu in the Eighth Route Army is even lower.

The reason why this is the case is because there are more than 10,000 people in Trojan County, and the fields are intensively cultivated, while most of the troops of the Eighth Route Army are semi-full-time, and the devils pick up guns to fight when they come, and pick up hoes to farm when the devils leave.

In this case, they can only adopt extensive planting, exchanging quantity for yield.

Now with chemical fertilizer, the yield per mu may jump several times from one hundred and fifty catties to three or four hundred catties, that kind of shock, it really makes Lei Ming and other people who are used to eating bran and swallowing vegetables, and eating a meal is the same as the New Year, and the guy who has never seen the world can't think about it.

In fact, not only them, but almost for the Chinese people whose first priority in this era is to make a living, they will die of happiness when they hear such a yield per mu.

Looking at the appearance of the three of them, Lu Yuan wanted to laugh and felt sad at the same time.

The funny thing is that even such a yield per mu, in his eyes, is a piece of cake, after all, after a few decades, the large-scale use of chemical fertilizers and the emergence of improved varieties, the yield per mu is thousands of catties at every turn, it is not a yes, the performance of the three people, in his eyes, is purely that the dog in the countryside has not been on the street, has not seen the world.
