Chapter 593: Blacksmith need its own hardware

After the improvement of Liu Ruian's purple alfalfa, its developed root system can provide a large amount of organic matter for the soil.
At the same time, it can also absorb calcium and decompose phosphate from the deep layer of the soil.
It is left in the cultivated layer, which is decomposed to form organic colloids, which can form stable aggregates in the soil, thereby improving the physical and chemical properties of the soil.
The nodule of alfalfa can also fix the nitrogen in the atmosphere to improve the fertility in the soil.
Each nodule of alfalfa grass contains 35 kg of nitrogen, 5.5 kg of total phosphorus, and 15 kg of total potassium.
Each mu can fix 50 kg of nitrogen from the air every year, which is equivalent to 150 kg of ammonium nitrate.
It is precisely because of this fertile field capacity that the farmland grows purple alfalfa grass during fallow, under normal circumstances, the field can be stably yielded without fertilization for three consecutive years.
The rate of production increase is usually 50% to 100%, and the higher one can be more than 2 times.
"Two times ..."
Although I don't understand professional terms such as nitrogen and total phosphorus and potassium, Liu Bocheng grasped the key immediately.
"Wouldn't it be said that after planting this purple alfalfa grass, the current acre yield can be doubled again?"
When I thought that the output of five kilograms per mu could be doubled again, no matter whether it was Liu Bocheng or Ke Qingshi, it was inevitable that he was on the spot.
"Theoretically this is the case, but in fact, it is impossible to achieve such a good effect." Liu Ruian shook his head, splashing cold water.
"Why is this again?" Ke Qing could not help asking.
"Xingdao 1 does have an excellent adaptability to soil, climate, temperature and other conditions." Liu Ruian said happily:
"But even so, if you want to get a high output, the conditions in all aspects can't be worse."
"The better the planting environment, the higher the output of Xingdao No. 1. On the contrary, the output will naturally decrease."
"Planting purple gold alfalfa grass during fallow period can quickly restore the fertility of the farmland where Xingdao 1 was planted."
"In this way, minus the coldest two months, Xingdao No. 1 can be planted for at least two seasons without worrying about lack of field power."
"As for output, it will indeed be improved, but it is difficult to really reach twice the theoretical value."
Faced with this answer, Liu Bocheng and Ke Qingshi were very disappointed.
No way, if the output can be doubled, can the output of Xingdao No. 1 per mu reach about 15,000 kg.
Even if the roughness ratio is 88%, about 13,000 kilograms of polished rice can be harvested.
According to the scale of Tangquan Farm, which is almost 15,000 mu, the planting of Xingdao No. 1 this season is almost 200 million catties, 100,000 tons!
Coupled with at least two seasons a year, it means that Tangquan Farm can produce 200,000 tons of rice every year.
No more, such a farm doubles 10,000 times, which is an annual output of 2 billion tons.
Putting such figures in the era of 1950 was enough to support the food consumption of the new Chinese population.
As for ten thousand times easier? It's really not difficult!
Ten thousand times as much as fifteen thousand mu, but only 150 million mu.
According to the statistics of the real world in 1996, the output of grain, cotton, oil and vegetables among the main agricultural products in Jinling City was 179.46, 0.37, 14.08 and 1.232 million tons respectively.
The total sown area of ​​crops is 6.399 million mu, of which the sown area of ​​grain crops is 4.3394 million mu.
Well, the area of ​​arable land in this period in 1950 must not be as much as it was in 1996, but with a little effort to reclaim, 1.5 million mu always has land.
According to the annual output of 15,000 mu of 20 tons, 1.5 million mu is 20 million tons.
Okay, I just said that doubling is unlikely, but what about doubling? This can always be achieved.
The annual output of 20 million tons is cut in half, and there are as many as 10 million tons.
This is just a city! Looking at the whole province, and even the whole country, how high will the output be? !
Looking at the coincidence and falling into contemplation, that is, the two people in the later generations commonly known as yy, Liu Ruian did not bother.
Instead, he asked Li Aiguo to let the other party run again and prepare lunch for him.
After a while, Liu Bocheng and Ke Qingshi came back one after another.
After the two looked at each other, a complex smile appeared on their faces.
"Before, I thought that if the grain in this area could be more than 1,000 kilograms per mu," Liu Bocheng said with emotion when looking at the farmland still harvesting grain:
"Whoever thinks about it, is now not satisfied with the production of five kilograms per mu. This person, sometimes just lacks the blessing."
"Yes, old Liu, we all think too much." Teacher Ke Qing on the side also smiled with emotion.
"The two leaders don't have to think too much. A country's strength and weakness can't just look at agriculture." Liu Rui'an, who was half-consolation and half-reminder, said:
"Even if the output of Xingdao 1 is high, it is true that there is no agricultural instability, but no matter how good it is, it is only stable."
"As the saying goes, it takes hard work to strike iron! Only if the country's military power is completely strong, Chinese talents can really stand up."
"Okay! Well said! Ironing also needs to be hard, which is quite good!" Liu Bocheng, a flash of polished eyes blocked by the glasses, praised.
"Truth, you are really good." Ke Qing, who was standing beside him, said with a smile on his face:
"But you also know that it wasn't long before New China was established, and you can say that everything is missing."
"If you want to make the military force completely strong, you need a lot of people with lofty ideals to throw their heads and sprinkle blood on it ~ EbookFREE.me ~ Uh ..." I found myself seeming to put myself in the pit, Liu Ruian's face How exciting the expression is.
"Haha ... Let me see, just let others do it by throwing their blood on their heads." Liu Bocheng, who reacted in an instant, said with a smile:
"If you are virtuous, I think it is most important to find ways to pour some good things into the country. Are you right, Master?"
"Yes, that's right!" Ke Qing replied with a smile.
Seeing that the two cooperated so well, Liu Ruian had to secretly praise his acting skills.
"The two leaders, do you know why I did this farm?" Liu Ruian asked with a wry smile, pointing at the farmland that was still harvesting.
"Instability without agriculture?" Liu Bocheng quickly uttered the answer he thought of.
"Yes, there is no farming instability!" Liu Ruian nodded and said seriously:
"It didn't take long for the country to be established. What we need now is not to become stronger, but to stabilize the internal situation first."
"Only by stabilizing the interior first, there will be no opportunity for enemy agents and imperialism."
"When the national situation slowly stabilizes, it will be time for us to show the Chinese muscles to the world !!"
