The Traverser of Marvel World

The developed root system of the alfalfa grass improved by Liu Rui'an 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.

Let it be left in the cultivation layer, and form organic colloid after decomposition, which can make the soil form stable aggregates, thereby improving the physical and chemical properties of the soil.

The root nodules of alfalfa grass can also fix nitrogen in the atmosphere to improve the fertility of the soil.

The root nodules of alfalfa per mu contain about 35 kg of nitrogen, 5.5 kg of total phosphorus, and 15 kg of total potassium.

Each mu can fix 50 kilograms of nitrogen from the air every year, which is equivalent to 150 kilograms of ammonium nitrate.

It is precisely because of this ability to fertilize the field that alfalfa grass is planted on the farmland when it is fallow. Under normal circumstances, the field can not be fertilized for three consecutive years and have a stable and high yield.

The yield increase range is usually 50% to 100%, and the higher one can reach more than 2 times.

"Twice..."

Although he didn't quite understand the technical terms such as nitrogen, total phosphorus and potassium, Liu Bocheng grasped the key immediately.

"Doesn't that mean that the current yield per mu can be doubled after planting this alfalfa grass?"

Thinking that the original 5,000-jin yield per mu could be doubled again, regardless of whether it was Liu Bocheng or Ke Qingshi, they couldn't help being stunned on the spot.

"That's the case in theory, but in reality, it's impossible to achieve such a good effect." Liu Ruian, who shook his head, poured cold water on it.

"Why is that?" Master Ke Qing couldn't help asking.

"Xingdao No. 1 does have excellent adaptability to soil, climate, and temperature conditions." Liu Rui'an talked eloquently:

"But even so, if you want to get a high output, the conditions in all aspects should not be bad."

"The better the planting environment, the higher the yield of Xingdao 1. On the contrary, the yield will naturally decrease."

"Planting alfalfa grass during the fallow period can quickly restore the fertility of the farmland that has been planted with Xingdao No. 1."

"In this way, minus the coldest two months, Xingdao No. 1 can be planted for at least two seasons without worrying about insufficient field strength."

"As for the output, there will indeed be an increase, but it is difficult to achieve twice the theoretical value."

Faced with such an answer, Liu Bocheng and Ke Qingshi were a little disappointed.

There is no way, if the yield can be doubled, wouldn't the yield of Xingdao No. 1 per mu reach about 15,000 catties.

Even if the roughness rate is 88%, about 13,000 catties of polished rice can be harvested.

According to the scale of Tangquan Farm, which is about 15,000 mu, the amount of Xingdao No. 1 planted this season will be nearly 200 million catties, or 100,000 tons!

Coupled with the ability to plant at least two seasons a year, it means that only Tangquan Farm can produce 200,000 tons of rice every year.

Not too much, if such a farm is doubled 10,000 times, it will have an annual output of 2 billion tons.

Such a figure was enough to support the food consumption of the new Chinese population in the era of 1950.

As for 10,000 times easier? It's really not difficult!

Ten thousand times 15,000 mu is only 150 million mu.

According to the statistics of the real world in 1996, among the main agricultural products in Jinling City, the output of grain, cotton, oil, and vegetables were 1,794,600, 0.37, 140,800, and 1,232,000 tons respectively.

The total sown area of ​​crops is 6.399 million mu,

Among them, the sown area of ​​food crops is 4.3394 million mu.

Well, the area of ​​arable land in this period in 1950 was certainly not as much as in 1996, but with a little effort to reclaim and reclaim, 1.5 million mu of land can always be found.

Based on an annual output of 20 tons per 15,000 mu, 1.5 million mu equals 20 million tons.

Well, I just said that doubling is unlikely, but what about doubling? This can always be won.

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, or even the whole country, how high will the output be? !

Looking at the two who coincided with each other and fell into deep thought, Liu Rui'an didn't disturb them either.

Instead, he called Li Aiguo and asked the other party to make another trip to prepare the lunch.

After a while, Liu Bocheng and Ke Qingshi came back to their senses one after another.

After the two looked at each other in blank dismay, complex smiles appeared on their faces in unison.

"Before, I thought it would be great if the grain in this field could produce more than a thousand catties per mu." Looking at the farmland that was still harvesting grain, Liu Bocheng said with emotion:

"Who would have thought that the yield of 5,000 catties per mu is not enough. This person, sometimes he is not blessed enough."

"That's right, old Liu, we all think too much." Master Ke Qing beside him also smiled with emotion.

"The two leaders don't need to think too much. The strength of a country cannot be determined only by agriculture." Liu Ruian, who was half comforting and half reminding, said:

"No matter how high the output of Xingdao No. 1 is, it is true that there is no stability without agriculture, but no matter how good it is, it is only stable."

"As the saying goes, you need to be strong to strike iron! Only when the military power of the country is completely strengthened can the Chinese truly stand up."

"Okay! That's a good point! You need to be strong to strike an iron, and that's a good point!" Liu Bocheng, whose eyes were covered by his glasses, flashed his eyes, and praised.

"Dezhi, what you said is indeed very good." Master Ke Qing, who was standing aside, said with a smile after his expression changed:

"But you also know that the founding of New China has not been long, and it can be said that everything is lacking."

"If you want to make the military power completely stronger, you need a lot of people with lofty ideals to throw their heads and blood."

"Uh..." Realizing that he seemed to have tricked himself into it, the expression on Liu Ruian's face suddenly became more and more wonderful.

"Haha... In my opinion, let others do the thing of throwing your head and blood." Liu Bocheng, who reacted instantly, said with a smile:

"In terms of virtue, I think it's most important to find a way to dump more good things into the country. Are you right, Master Qing?"

"Yes, that's right!" Ke Qingshi replied with a smile.

Seeing how these two cooperated so tacitly, Liu Rui'an had to secretly praise his acting skills.

"Two leaders, do you know why I started this farm?" Liu Ruian asked with a wry smile, pointing to the farmland that was still being harvested.

"There is no stability without agriculture?" Liu Bocheng quickly said the answer he thought of.

"That's right, no farming is unstable!" Liu Ruian nodded, and said earnestly:

"The country has only been established for a short time. What we need now is not to become stronger, but to stabilize the internal situation first."

"Only by stabilizing the interior first, will we not be taken advantage of by enemy agents and imperialism."

"When the situation in the country gradually stabilizes, then it will be time for us to show the muscles of the Chinese people to the world!!"
