"Have you calculated that per capita can cultivate land?" Huo Gang knocked on the table and asked.

The arable land that Huo Gang asked was not how much arable land there was, but how much land a person could cultivate if he could take care of all the land.

"Looking back at the leader's words, according to our exchanges with Minister Yang Wu and Minister Wang Shan, our seeder can be put into use in the spring next year, so that if the per capita arable land is calculated, if the wheat is simply planted, the field that can be planted by each person can be planted at least 30 acres or more! Mainly limited by the harvest period. Shi Wannian immediately spoke.

Huo Gang raised his head in some surprise: "Did the seeder come out?" ”

The wheat planter is actually not difficult, and in fact, its technical difficulty is not so high, Huo Gang vaguely remembered that when he was a child, the seeder for planting wheat was pulled by a horse, as if planting seven rows of wheat at one time, the first three and the last four have a total of seven mouths, and the middle trough is put into the wheat and mixed fertilizer base fertilizer, and then when sowing, the wheat is sown along the groove opened by the 7 legs to complete the sowing.

This is actually not very difficult, Huo Gang remembered that most of them were made of iron and wood, including the wheels on both sides were iron, the only difficulty might be the chain, but the chain was nothing more than a little heavy, which did not affect its sharing.

But Huo Gang didn't know much about this, but he could roughly tell Lu Mu and them, but what made Huo Gang a little surprised was that Lu Mu told Huo Gang that there was actually such a seeder, called a cocoon car, made of pure wood, and probably had two legs.

What Huo Gang described is nothing more than the advancement of the cocoon, for the big man who has the initial finishing ability of steel, it is not difficult to make this kind of one-time planting of 7 ridges, or even more cocoons.

But he didn't expect this thing to be developed so quickly.

If the seeder is developed, then it is really not difficult for a person to plant 30 acres of land.

First of all, there is no interplanting in this era, it is all single wheat, and most of the interplanting wheat can only be carried out with sunflowers and corn, but these two crops are not currently available here in Huo Gang, and other crops can hardly be interplanted, as if soybeans (that is, soybeans, and some areas in the north call broad beans soybeans) can also be interplanted.

For example, wheat is harvested in July, but in the Western Regions, it is perfectly acceptable for maize, which grows until October, and the weather conditions permit. In this way, the wheat fields will not be completely empty.

Of course, according to Huo Gang's practice last year, it is also possible to plant Chinese cabbage immediately after the wheat is harvested, so as to enrich the people's table food.

But the problem of planting is that it will prolong the time for farmers to cultivate the land, not that Huo Gang wants farmers to rest, the Chinese have been incomparably industrious since ancient times, not to mention that now, even if the farmers are more than a thousand years later, most of them are mechanized, and they do not say that they will rest directly after harvesting.

But Huo Gang wants them to work, now in the industrial city, the number of workers required for coal mines is increasing, it is foreseeable that the number of workers in Dahan will inevitably be seriously insufficient, of course, the use of machines is one aspect, but in 628 this year, the number of workers needed in construction alone is a massive number.

The main thing is that the road from Yumen Pass to Yiwu City will complete the construction of concrete roads this year, as well as the roads from coal mines and iron mines to the Industrial City, as well as the roads from the Industrial City to Loulan City, Loulan City to Yanqi City, and the official roads of several counties near Yanqi will all be built.

Yumen Pass to Yiwu City, the road linking the coal mine and the iron mine has completed the preliminary roadbed paving, and the laying of the concrete pavement will be left next year, the speed should be very fast, and the other roads are starting from scratch, and the official road between Yiwu City and Loulan is also to be built.

According to Huo Gang's estimates, there will be at least 50,000 to 80,000 young construction workers on these roads alone.

With so much manpower, land cultivation is bound to be a problem.

Of course, although it is nothing to reduce the planting area of grain, it will definitely be enough for them to eat anyway, but the reason why Huo Gang grows more grain is that he wants to take advantage of the natural disasters in Datang in the next few years, and wants to sell grain to Datang at a low price, or even at a low price!

As for why it is sold so much, it is very simple, as long as Datang can be fully supplied with enough grain, then it means that those people in Datang find that they can buy more grain from planting cotton and other cash crops than they can earn from growing grain, then they will naturally choose to plant cotton.

At least the real big landlords of Datang will choose this way, when they grow cotton, and their textile industry is not comparable to the Han, then the cotton Dahan can import, after importing all kinds of cotton cloth, and then attach high-value, high-output value cloth to sell back to Datang.

In the process, it is estimated that anyone in future generations will know what this behavior is like.

Therefore, the grain must be guaranteed, and as long as the grain is guaranteed, Datang will not be short of grain, with Li Shimin's next method, he estimates that he will start to control the north in large quantities and implement the plan that Huo Gang said.

Because all the wealth in the state of technology addition, will eventually flow to the big man.

And in this process, in fact, Datang will become more and more prosperous, at least the population will increase, and it is inevitable that the people will live and work in peace and contentment, but to put it bluntly, if you develop faster, I will develop faster, this is the gap.

Then if you plant wheat alone, you can solve the problem of human labor, because the main labor demand for single wheat is in several time points such as sowing and harvesting, and Huo Gang can directly call on the national power to carry out centralized harvesting in these seasons.

However, interplanting soybeans is also very tempting, because soybeans can be squeezed for oil, and the leftover from oil can be fed to pigs and increase meat, and then after having oil, then stir-fry can be put on the agenda, of course, it is also possible to eat meat oil, but it is unlikely that meat oil will supply everyone.

It seems like...... Huo Gang thought of another thing, it seems that sugar beets can also be grown, right? Beet Huo Gang remembers correctly, the stems and leaves of this thing can always be used to feed pigs, and when the beet Akita is harvested, it can be used to make sugar, so the leaves can always be fed to pigs with the bran of wheat, which is also a good thing for raising pigs.

However, beets seem to have originated near the Mediterranean Sea, and this point in time is definitely there, this Huo Gang can inquire with the merchants of Dashi, these things Huo Gang feels that they can be handed over to the people to choose, for example, sugar beets, if they only plant two or three acres per household, it is almost not a problem to feed pigs, and it is not a problem to feed pigs with wheat bran in winter.

Of course, the biggest role of beet is to make sugar, as for its other by-products, such as methanol, ethanol, butanol, glycerin, monosodium glutamate, etc., Huo Gang has that kind of chemical method now, and it is estimated that it will not be able to be used in a short time.

But is it certainly possible to feed pigs as a by-product of sugar beet sugar to farmers, or sell them to pig farms on a large scale?

Huo Gang's mind began to think wildly, and the ministers below looked at each other a little, they didn't know what their leader asked, and after they didn't speak, they began to think alone.

But they didn't bother, for they all knew that many things in the Han had come from the leader's careless thinking.

After pondering for a moment, Huo just raised his head and said: "In this way, next year, we must ensure that at least 10 million mu of arable land can be cultivated, and in addition, ensure that after the wheat harvest is completed, all the people can plant some Chinese cabbage. ”

"It's already spread in some areas, and we'll do it again this spring when we promote different seeds." Wang Shan immediately said, this is a matter for their Ministry of Agriculture.

"Well, you can record this matter, by the way, introduce soybean seeds from Datang, as well as different radish seeds, which can be tentatively planted after the wheat harvest, but before it is promoted to the people, the Ministry of Agriculture will set up an agricultural research institute after this year." Huo Gang thought for a while and said.

"Agricultural Research Institute?" Wang Shan was a little confused.

"The main task of the Institute of Agricultural Sciences is to study various varieties of seeds, such as selecting excellent seeds, looking for longer ears of wheat from various wheat fields for seed retention, and then cross-planting with some wild wheat varieties such as drought resistance, disease and pest resistance, etc., so as to breed more excellent wheat varieties." Huo Gang thought about it for a while and gave an example.

Hearing Huo Gang say this, Wang Shan immediately quickly lowered his head and recorded, now the entire Han has begun to promote the fountain pen, although it is the most elementary dipping ink fountain pen, but the speed of writing is much faster than that of a brush.

"Chief, do I think this agricultural research institute should select some people with more professional cultural knowledge to come in?" Mingyue thought for a while and asked.

"This is for sure, but in the early stage, we can't focus on these people, and select some old farmers with rich planting experience in the early stage, these old farmers may not have cultural knowledge, but their lifetime experience is enough for them to know how to increase crops, what kind of situation can avoid pests and diseases, etc., these are experiences. Some talented students in this area can be selected in the early stage, and the children will be apprentices to these old farmers. Huo Gang said seriously.

"Let them learn and practice at the same time, and when the time comes, after completing the basic learning, the school will offer a biology course." Huo Gang added.

"Yes!" Wang Shan and Wu Ping hurriedly agreed, although Wu Ping is the prime minister, Wu Ping is still the minister of the Ministry of Education, and this matter is naturally related to him.
