The output of feed has promoted the output of a large amount of meat, and it has also changed the best food for physique, milk and eggs, in large quantities throughout China, this emergence also has a process, in the early stage, there is no way to popularize it to everyone, eggs need to be produced, and the same is true for milk and goat milk, especially cow and goat milk, even if there is enough feed, there may not be enough dairy goat cows, which needs to be cultivated.

It was only a temporary satisfaction, and then, along with the large-scale planting of corn and the large-scale production of feed, under the premise of having enough raw materials, the entire Dinghai popularized the output of pigs and poultry, so that the dietary structure of the entire Dinghai was changed on a large scale.

The popularization of corn seems to be slow, but in fact, it is very fast, starting from the thirteenth year of Qingli and continuing until the fifteenth year of Qingli, reaching the limit in the fifteenth year of Qingli, and finally under the premise that there is no large-scale expansion of the territory of the Dinghai Navy, 700 million mu is already a limit.

With the large-scale expansion of corn planting area, the price of corn has also fluctuated greatly, and in more than two years, corn has begun to fall rapidly from a rarity that has just appeared, and the price drop is very terrible.

At the beginning, the price of a corn cob ranged from 1 to 3 runs, when 2 million acres of land, a total of 16.5 million stone of corn was produced, which was selected, more than 8 percent of the seeds should be retained, plus the loss, after all, in the selection process, only the grains are full, will be selected as seeds, under the premise of not enough seeds, those that are eliminated, basically, are all such and such problems.

If you remove the bad corn and remove some that are not suitable for food, it will be good to have one percent of the remaining corn in the end.

Nearly 9 percent of them are used as seeds, which are left for planting next year, that is, only 10 percent will enter the market, that is, 1.65 million stones.

The weight of corn is not small, if it is not dried, according to the calculation of two corn cobs per catty, that is, more than 300 million corn cobs, it sounds like a lot, and it has reached the level of 100 million, but when you think of the population of the Dinghai Navy, close to 100 million people, one-third of children, more than 30 million children, even if you remove the age of 2, there is no way to eat corn, and those over 2 years old have 10 or 20 million, and it is impossible for everyone to average 15.

The reason why food is food is because food is eaten every day, even if you are full at one meal, you also need to eat the next meal, so on the premise, the amount of corn that each child eats is a lot.

If you spend 2-3 yuan elsewhere, buy a meal for your child, which is unimaginable, two or three are difficult, but in Dingjun, under the premise of an average monthly salary of about 300 yuan, buy one or two for your child as a taste, which is completely acceptable.

Children eat, is just needed, but the taste of corn is very good, even ordinary people, they like to eat, as a rare thing, more people eat it, so on average, maybe each person eats a few more, it is not enough, which makes this corn more demanding.

Scarcity is expensive, there are fewer things, more people buy them, and of course the price soars, which is the last, dumbfounded price.

At the beginning, Zhao Xin set the price of 1 guan, in his feeling, it was already very high, according to the price of rice, he could buy 150 catties of rice, which is equivalent to the price of 450 yuan a corn in later generations, with more and more people buying, the price of 1 guan could not withstand it at all, and later rose to 2 guan and 3 guan.

After 3 times, it no longer rose, the reason is very simple, after a series of concentrated delivery, the corn has been eaten, a total of 1.65 million stone, that is, it has been supplied for almost 2 months, and it has not even waited for the New Year, and it has been sold out.

On the contrary, during the Chinese New Year, some people want to eat, but they don't eat, which is very troublesome, and finally things are getting bigger and bigger, getting to the cabinet, and even alarming Zhao Xin, there is no way, there are too many people, what has been produced, there is no way to eat it again, and the rest must be left in the large-scale popularization, of course, it is impossible to take it out and eat.

At this time, in the grain research institute, there are special greenhouses to grow corn, about 6,000 acres, itself is improved and seed research, this batch of seeds, because the heredity is not very good, can not exist as seeds, itself, is prepared for other uses, or as canned food, or processed into other food.

Now, in the corn cob, there is a huge demand under the premise that it can be taken out and used, 6,000 acres of corn, the yield per mu is about 9 stones, that is, 54,000 stones, close to 5.4 million catties, although this number is still not much, it is impossible to supply the entire demand, but in the New Year, it is a good choice.

This batch of corn that was urgently squeezed out was also sold at a very high price during the New Year's Festival, and one was as high as 5 yuan.

Even if it is only more than 2 million mu, even if it is only one-tenth of the output, the total amount is almost 350 million yuan, which is the advantage of the new product, but this advantage will not be able to be maintained soon.

If Zhao Xin is just a person who pursues just interests, he will not expand the yield of corn on a large scale, a certain amount of corn can create relatively high profits for a long time, once it is popularized on a large scale, the price of corn will definitely not be so high.

It seems that 1.65 million stones were sold at a high price of 3 times, but if it is increased by 10 times, will it be 3 times, 100 times, 1000 times, and the scarcity is expensive.

Zhao Xin, as the emperor of China, can unceremoniously say that the entire Dinghai Navy is his wealth, even if he does not use the method of harvesting power, it is some enterprises invested by Zhao Xin, and some enterprises he founded, and Zhao Xin's money in his hands can be countless.

Of course, Zhao Xin will not be short-sighted, for the sake of hundreds of millions of dollars, and ignore the huge role of corn, corn is one of the best things to change the human race and improve the structure of the human body, and it must be promoted on a large scale.

Under the premise of Zhao Xin's sparing no effort to promote on a large scale, the planting area of corn has expanded almost at a rate of nearly 100 times per year, from the first batch of 2 million mu, to the second batch of 140 million mu, and then to the third batch, reaching the limit, 700 million mu.

Corn is a high-yield crop, the rate is very terrible, which is also the root of high yield of corn, in order to expand the planting scale, the first batch of large-scale planting, most of the seeds are retained, but to the second batch, the total amount of planting is more than 140 million acres under the premise, this year's things, there is no need to keep the seeds.

According to the appearance of 100 times, that is, 14 billion acres of land are needed, which is more than ten times the total land for the current Dingjun, and it is impossible for the Dinghai Navy to plant corn comprehensively.

With the popularization of a large number of corn, in the fourteenth year of Qingli, the planting area has exceeded 140 million mu, and the income is 1 billion stones.

1 billion stones, if you say, the 100 million people in the Dinghai Navy, all eat corn, they can't eat it all, in the Northern Song Dynasty, because of the lack of oil and water, everyone eats a lot of food every year, but no matter how much, it will not exceed 600 catties, that is, more than 50 catties of grain per month, and this amount is close to 2 catties on average every day.

This is pure grain, not a finished grain, but an average of 10 stone per person, that is, 1000 catties, so that the average per day, it is more than 3 catties, this grain, no matter what, can not be eaten, not to mention, now the Dingjun has popularized all kinds of non-staple foods and meat, plus supplementary foods such as fruits, the intake of food has been greatly reduced, and 1 catty can be eaten a day, which is already very high.

The relationship between supply and demand is always an important factor in price, when there are many people who buy and the supply is insufficient, the price soars immediately, but when the supply is sufficient and the buyers are small, the goods are backlogged, and if you want to sell them, you must reduce the price.

In fact, this is the case, even if we do not consider the problem of enlarged production, it turns out that the price of corn immediately plummeted by 3,000 feet by expanding the yield by 1000 times and the actual supply by 1,000 times.

Although the overall price is several times more expensive than flour and rice when measured in terms of weight, it is almost a world away from the beginning, and the decline is very obvious.

This is not the end, to the fifteenth year of Qingli, the planting area of corn has finally reached the limit, in the entire north, including Japan and North Korea, a total of 700 million acres of corn have been planted, then the final harvest, as high as 6.7 billion stones, the total amount of planting, has been terrible to a considerable extent, corn has finally, from a rarity, quickly falling, into the most common food crops, the price reached 500 Wen per stone, and reduced by five or six times, becoming the cheapest grain.

This is a very reasonable price, because of the problems of transportation and labor costs, plus some taxes, the price of grain is relatively high, the price of flour is about 800 wen per stone, and the price of rice is about 1200 wen.

Rice is 2.4 times higher than corn, which is relatively high, but it is also a moderate price, after all, the yield of corn is too large, and the planting area is also very terrible.

At the beginning, the first test of planting, reached about 8 stone per mu, through two or three years of time, cultivate improved seeds, strengthen planting management, summed up a series of corn planting methods and methods, finally, let the mu yield begin to increase, in the best field, after a certain degree of breeding, the limit weight will reach 11 stone, the average also more than 9.5 stone,

Such a yield per mu, so that planting an acre of corn, equivalent to 2 acres of rice, this, although the yield of rice, is more than 5 stones, but after processing, threshing, polishing and a series of treatments, the total yield of rice, must be less than 4 stones, but corn, in addition to threshing, there is no other work to do, even to a certain extent, not drying, can also.

The emergence of corn, and large-scale popularization, but not the main food of the Dinghai, as a concoction can, as a staple food, that can't work, the Chinese occasionally try it is okay, if every day is corn cob, corn grits, corn kernels, I am afraid the stomach will not be able to stand it.

At the same time, the land occupied by the Dinghai Navy is about 180,000 mu or so, and the planting area of 700 million mu is already more than one-third.

In terms of food, the people of Dinghai still prefer to eat rice noodles, and they occasionally eat a little bit of grain, but it is okay to eat for a long time, and it is not the choice of many people.

Most of the corn is used as a raw material, such as winemaking, Dinghai is located in a high latitude, in order to keep warm, drinking has become an inevitable choice, and as a raw material for industry, a small number of them have also entered the field of food processing, although the taste of this corn is not very good, but through the processing of starch, there are other things, or edible.

After the corn planting area exceeds 700 million mu, the utilization rate of corn stalk is also declining, no way, all corn can not be made into feed, not to mention the added part, just say that the corn itself, 700 million mu, represents 2.1 billion tons of feed, even if it is a 10-to-1 proportion of roughage, 2.1 billion tons of feed, can also produce 210 million tons of meat.

Based on the current population of the entire Dinghai Navy and the Northern Song Dynasty combined, no one can eat more than a ton of meat on average every year, even if they eat all the meat.

Not to mention, it is unrealistic to complete such a huge corn stalk that is spread throughout the land area of the Dinghai Navy and processed into fodder.

Pick a better one, more suitable for processing processing, but also strengthen the distance relationship, some too far away from the feed mill in fact, is abandoned.

Of course, the method of green storage has also been publicized to everyone, if the workers, if they have leisure, they can save some of the green storage, for their own livestock to breed, this is also possible, but these utilization rates are not high, just sporadic, a person's ability is limited, even if there is a perfect, scientific method, but can only produce a small amount of feed, plus breeding, generally speaking, just the simplest breeding, one or two pigs, dozens of chickens.

For this, Zhao Xin has no way, can only popularize the crusher as much as possible, after crushing these straws, after a certain amount of fermentation, as a base fertilizer, put into the soil, although it is said that this will occupy a considerable number of people, and generate a certain cost, but it is the most suitable method to deal with corn stalks, otherwise, it must be the same as later generations, directly burned, that is the worst method, not only pollute the environment, but also have no way to produce any benefits.

The discovery of corn has made earth-shaking changes in the Dinghai Navy, which has also stimulated the exploration fleet from the side, the three major crops in the Americas, only one has been found, and the other two, they also need to work harder.
