As He Zilong, who is a young man, the Chinese of the same era are counted three generations upward, basically including Taizu, who is not a farmer?

Even, He Zilong's family, who became workers, will have a busy farming festival every year, and they have to go back to their hometown to help with farming.

If we say that China's peasants have a population of 800 million, then at least 600 million people's planting income is related to these three varieties -- their audience is far larger than that of fruits, grains, oilseeds, vegetables and other agricultural products, and the groups they face are also diverse.

According to the results released by the Corn High Yield Competition (NCYC), the highest yield of corn in the United States in recent years is 2,269 kilograms.

Maybe some people who don't farm will listen to it and say that this is nonsense.

In fact, under the guidance of modern technology, the yield level of corn has been on the rise since the 20th century, and the highest yield of corn in China is currently 1.5 tons. This is still the nineties, if in the past twenty or thirty years, to reach the level of the United States, that is, 4000-5000 catties per mu of output.

Of course, not all fields are suitable for corn production, and some fields are planted by you, and the yield is not too high.

But if you include the whole country, on average, the yield per mu is 600-800 kilograms. Of course, the cost of paying for high yield is also high, that is, with various costs and labor costs, the cost of corn planting is about 1083.72 yuan per mu.

This is also the reason why in the good world, a corn cob costs a few dollars a piece.

Of course, if it weren't for a full stomach, He Zilong would prefer to grow ginger rather than worthless corn. After all, in today's continuous progress in agriculture, simply growing food can no longer keep up with the pace of development of the times, and it is found that such cash crops as ginger, cotton, potatoes, and garlic are very popular and expensive in the market and life.

The yield of ginger per mu is mostly more than 7,000 catties, the price is high (about 2 yuan a catty in the storage cellar), and the income of 20,000 yuan per mu is not a big problem.

On the other hand, the income of planting corn per acre is only 1,600 yuan. The cost of planting corn per mu is 1100-1200 yuan (150 yuan for machinery, 250 yuan for fertilizer, 50 yuan for seeds, 100 yuan for watering, and 500 yuan for labor).

The main thing is that after the country joined the international commercialization, more and more cheap corn was imported.

Of course, now it's the underground world, and it's not about the economy, where money is worthless, it's useless. Survival and a full stomach are the primary concerns.

As He Zilong thought, sure enough, after living here temporarily, he didn't wait to build his own temporary house.

He Zilong and his entourage received a job, a so-called exercise, saying that they would help take care of the acres of corn land next to He Zilong and others. If it is possible to ensure that there will be no large-scale destruction and yield reduction when the results are reached, 20% of the yield can be supplied to them.

"The yield is counted in ten days......," said the messenger.

"Ten days or so, so fast, it's not mature, it's only such a short ......time," He Zilong and the others exclaimed.

"Hmm, you haven't planted golden beans, they all ripen every ten days,......" The messenger looked at He Zilong with eyes like looking at soil buns, and after discovering that they really didn't understand, he briefly explained a few times.

Watching the envoy go away, He Zilong and his friends glanced at each other, they never expected it. The corn in the underworld, which is called the golden bean, only takes about ten days on average from growing, flowering to fruiting.

No wonder, looking at this fruiting rate, knowing that the yield is not high, will insist on planting, instead of going to the forest to find wild vegetables, wild fruits as the staple food. So against the sky?

You know, in the outer surface world, it takes 35-45 days for corn to mature from flowering to fruiting. This is three or four times faster here, so even if the yield per mu is only about 100 kilograms, but because it can bear fruit three times a month, it seems that it is not much worse than the yield of the garbage outside the soil.

"Maybe it's just something like corn, or maybe it's a mutant corn......," one employee said.

"You mean genetically modified corn, but genetically modified corn is not so fast, this TM has become super genetically modified, right......?" someone complained.

The word genetically modified was not considered negative in the nineties, unlike twenty or thirty years later, when people heard about genetically modified organisms, people thought that it was garbage and a food with hidden dangers, but the price was indeed cheap.

Of course, there is no scientific proof that genetically modified food mouths are harmful.

"I see that the people here are tall and big, and they have a lot of strength, and the fertility rate is not low, and they are still making people on the street in the daytime, and there are babies on the side, if there are genetically modified products that mature in ten days, there is this effect, I would rather eat genetically modified food......" He Zilong's heart was also crazy and complaining.

Of course, before he was reborn in his previous life, he had been eating genetically modified food, whether he was active or not, you couldn't avoid it.

Because, as long as you order fast food and takeout, or go to a restaurant to eat, those places must be made with cooking oil made from genetically modified foods.

Looking back, he looked at the acres of corn fields that his people were in charge of.

It's just that it matures so quickly, and then look at the corn in front of you, most of them are ready to flower, if you say that 20% of the yield belongs to yourself and others, then you have to use dim sum, this is to work for yourself, not for others.

"Come, divide half of the people to build temporary houses, and the other half prepare them, build soil clothes, and control the weeds and layout of the cornfield. If we can't increase the yield, then divide 20% of the corn, I'm afraid we will have to go out hunting every day. It's monsters, it's dinosaurs, it's hostile forces, it's really a day where people can die......" He Zilong shouted to his friends.

When everyone heard this, compared to the tiredness of labor, people may die when they go out, and in contrast, everyone knows what to do.

So, under the command of He Zilong and the captain, some people went to build temporary houses.

Others have started to build soil fertilizers, but if the corn matures so quickly, as long as the fertilizer is applied properly, the results can be seen in a few days, and the effort will pay off.

The so-called soil fertilizer is soil ammonium sulfate!

The raw materials of self-made soil fertilizer are extensive, the method is simple, economical and practical, and its fertilizer efficiency is no less than that of chemical fertilizer. The formula is, 50 kg of fresh cow dung in ammonia (here it is replaced by animal feces of the surrounding warriors), 50 grams of soybean flour, (with similar plants, there are some around), 5 kg of cooked gypsum powder (this is still easy to find), sealed and placed below 25 °C for 3 days (only a test is required here, and it is OK to put it for about a day), and the fertilizer efficiency is higher than that of ammonia when applying 3 times the water.

Steamed bone meal (also known as defatted bone meal) is a bone extracted from fat by solvent, and then crushed by high temperature steaming, which contains 1.50%~5% nitrogen. It contains 16%~25% phosphorus pentoxide, and its fertilizer efficiency is also high.

When the soil and chemical fertilizer were applied, He Zilong smiled at the captain Lao Niu and said: "You said that you can increase the grain yield per mu by one or two times, or even more, and 20% is almost equivalent to the current yield per mu, if this thing spreads, we are afraid that we will immediately become the status of the great druid Yuan Xping in the minds of the underground natives, right? How much is this worth......?"
