No agriculture is unstable, this sentence is a country, it is not wrong to say an island, although it is said that from Quanzhou, from the Dinghai Navy, a little faster, but they do not last, Ryukyu itself, is an island suitable for planting, located in the tropics, can be harvested twice a year, proper development, you can make Ryukyu, get strong support.

Although it is said that it is not a waste to start agriculture now, a little earlier, the fertile soil in the Taipei area, coupled with the excellent seeds of the Dinghai Navy, will definitely be able to obtain a good harvest, as long as a year, the Taipei Basin has the ability to undertake more than 100,000 people, that is the time for large-scale development.

Dingjun's agriculture is now very developed, because of the cost of synthetic ammonia, urea is temporary, there is still no way to produce it, but the combination of farm fertilizer and improved varieties has made Dingjun's agriculture out of another way.

In the greenhouse state of the laboratory, in a year, the improved varieties of the Dinghai Navy can grow for 3 seasons, and referring to the breeding of improved varieties in later generations, this is the simplest, just know the theory, you can implement the agricultural technology, has already been opened in the Dinghai.

Darwin's theory of evolution revealed the development of the natural world and thus promoted the development of plant technology.

In the same cultivated land, various plants show different characteristics, and the evolutionary method is constantly reinforcing the advantages.

This method itself is the method of the whole grain planting, and when the old farmers choose the seeds, they will not choose the worst, but choose the fullest and the best grains, which is itself a process of natural selection.

However, this is not enough for real plant technology, because strengthening one trait alone will have some shortcomings in other traits, and the progress of each generation is not obvious.

In the entire history of Chinese cultivation, whether it is wheat or rice, there has been a transformation from nature to artificial cultivation, and then slowly increase the yield, occasionally too much, and there will be a regression.

The cultivation of improved seeds is completely different from this artificial seed retention, and the yield is the most critical, but other items are not missed, such as resistance to pests and diseases, and lodging resistance.

The cultivation of a single item alone is easy to make this single item get a huge improvement, and then, it is hybridization, in the process of hybridization, leaving all or most of the dominant varieties, and then put into the market.

At present, the agricultural science and technology of the Dinghai Navy cannot achieve such a degree, but after several years of training, it has still achieved certain results.

You must know that under the premise of providing reasonable fertility without the use of chemical fertilizers, even if the seeds left by farmers look full, they may not have the best potential among the whole seeds.

In the planting of agricultural science and technology, all kinds of fertilizers are added according to the proportion, after the best calculation, the output is much higher than that of ordinary farmland, the best is selected from the middle, and through a series of hybrid means, so that this advantage is solidified, and then the advantage is obvious.

It is conservatively estimated that in terms of yield, the limit yield is at least about 30% higher than before, and after fertilization, the effect is even better.

At present, in the small fields of the Institute of Agricultural Sciences, the yield of wheat has even reached 7.5 stones, and when it is put in the field and carefully cared for, it can also reach an average of 5.5 stones.

For example, the fields of Miaojiazhuang in Baozhou, all the seeds that have been planted belong to the land of Renzong Huangzhuang, and they have been planted about 3 percent, and the rest are some businessmen who have a close relationship with the Dinghai Navy and have always had dealings.

It's not that it won't continue to expand, but that the land of the Agricultural Science Institute of the Dinghai Navy is limited, and the seeds produced each year may only be able to supply about 200,000 mu of land.

The development of the Taipei Basin is also a direction, among the first batch of personnel, 12 experts from the Institute of Agricultural Sciences, and more than 100 people who are familiar with farming, and even know the cultivation process of the Institute of Agricultural Sciences, their task, in addition to developing the land near Taipei as much as possible, and then expanding the Institute of Agricultural Sciences.

Zhao Xin has always been aware of one point, no work, no wealth, no farming, no stability.

With the wealth of the Northern Song Dynasty, industry only played the role of icing on the cake, and even at the level of industry like Britain, it was impossible to exchange industrial products for more grain by dumping them around.

Although it is said that around the Northern Song Dynasty, there are many grain-producing areas, but the people in those places are very lazy, and industrial products may be able to push them to carry out grain production, but the natural habit is not developed after they obtain a certain product.

By now, the Northern Song Dynasty has a population of 100 million, and with the passage of Zhao Xin, as well as the emergence of various products and technologies, the population of the Northern Song Dynasty must grow rapidly, which is a problem.

There is no way to do natural population growth even in the 21st century, and why family planning is practiced is considered anti-humanitarian in other countries of the world, but it has to be so.

China's arable land area is too small, if it were not for family planning, which controlled the explosive growth of the population, China's population, by the 21st century, and then hundreds of millions of people, would be a big trouble, simply solving the problem of food rations, is an absolutely big problem, population growth simply cannot wait for the progress of food science and technology, when the time comes, once the turmoil starts, everything will be over.

This is also Zhao Xin's Dinghai, based on industry, but has never relaxed agriculture, even if there is no farmland in Dinghai, and the land is very scarce, but he has also drawn at least 10 square kilometers of land for the construction of the Agricultural Science Institute, you know, this is one-thirtieth of the total area of the Dinghai.

After years of investment, the seeds are finally on the right track, and they have begun to produce initial income, with rice, wheat and cotton as the main body of seeds, began to gradually affect the agriculture of the entire Northern Song Dynasty, not to mention, the current wheat 200,000 acres of planting, 300,000 acres of rice, and nearly 1.2 million acres of cotton, will produce results in the next year, all the farmland planted with these, their yield, will rise on a large scale.

600 people, if according to the traditional model of the Northern Song Dynasty, one person died 10 acres of land, this is not intensive cultivation, but similar to extensive planting, such a planting method, one acre of land can produce 2 stones is already good.

However, the research of agricultural science and technology, in addition to seeds and fertilizers, also has agricultural technology.

In fact, in the event of a massive recruitment of workers, it is almost certain that industry will compete with agriculture for population, and if it becomes acute, it will even cause unrest.

After all, everyone is oriented to a good life, and the salary level offered by the navy is fixed, as long as they have come to the navy and can accept labor, in this case, it is very likely that the peasants will come to work in the navy in order to live a good life, and even give up planting.

Sufficient labor force is a good thing for the Dinghai Navy, but because of this, it affects the entire grain production, which is not a good thing.

No matter how developed the industry is in later generations, there is one most basic thing that can never be ignored, that is, the total amount of grain.

If there is not enough food, no matter how much money, no matter how much gold, what is the use, if industry does not have basic food as a support, it will become a tree without roots.

Of course, compared with industry, the total amount of agriculture is not high, as long as it is enough to feed the population and has a slight surplus, it is enough, and no amount of grain can only bring about depreciation, and nothing else.

In order to strengthen labor efficiency, Zhao Xin led the combination of the Academy of Agricultural Sciences and the iron and steel mill to develop new agricultural tools.

In Zhao Xin's opinion, the most suitable for development was tractors and combine harvesters, but unfortunately, under the premise that there was no large-scale breakthrough in the steam engine, even if the steam engine was made, it only had the effect of experimentation, but not the effect of practical use, and even if it was barely made, the cost was too high.

If you can't make a tractor, it may not be impossible, and you can modify the existing farm tools, for example, with harder, sharper tools, which can reduce the consumption of livestock when ploughing the land, and you can cultivate more land at the same time.

In the same way, referring to the methods of tractors and combine harvesters in later generations, a larger plough was made, for example, a plough that could be operated by eight or even ten oxen together, which may not have much effect on Jiangnan, which is divided into small plots, but for large plots, this is no problem.

The Taipei Basin, after clearing the aborigines, is a wilderness, and after cutting down trees and weeds, it is natural land.

There are many similar farming tools, and the development of science and technology in Dinghai, especially the research of basic theories such as mechanics, the in-depth study of physics and chemistry, and some small tools that can save labor.

It will take time for these tools to be implemented, and it may take more than ten or twenty years to fully promote them, and this is still under the premise of making substantial concessions and saving costs in the Dinghai Navy, but this problem does not exist in the Dinghai Navy itself.

The small island of the Dinghai Navy, that is, more than 300 square kilometers of land, even if all of it is turned into fertile land, it is only 450,000 mu, which sounds very high, but for the Dinghai Navy, it is not enough at all.

According to the peak era, the population of 10 million people in the navy is calculated, and the annual consumption alone is as high as 30 million stones, that is to say, it may take hundreds of stones to support the consumption of one acre of land.

In fact, the land may be hundreds of stones, unless it is planted with sweet potatoes, the yield of an acre of land is 8,000 catties, or even 10,000 catties of this, ordinary grain, the highest yield, is just corn, when the wheat barely reaches 1,000 catties, the yield of corn has already exceeded 1,000 kilograms, and the limit can even reach more than 1,300 kilograms.

Not to mention, if you grow food, you can't have so many people, this is a competing data.

At present, the development of the Taipei Basin, although it is said that the Taipei Basin is about the same size as the Dinghai Navy, that is, more than 300 square kilometers, but aside from the future settlements and cities, there is no problem in dividing 200 square kilometers of land, which means 300,000 mu.

A 300,000 mu of farmland, through the Dinghai Navy's scientific and technological planting, planted some high-yield crops, even if the average reaches 5 stones, that is, the output of 1.5 million stones, two crops a year, conservative is also 2.5 million stones, which can feed at least 800,000 people, this is the foundation of large-scale development.

When an island can meet the food self-sufficiency, large-scale immigration can be carried out, and the most obvious difference between Ryukyu and the Dinghai Navy is that Ryukyu is deep into the ocean, and the closest distance from the mainland is more than 100 kilometers.

In the ocean, twenty or thirty kilometers and one or two hundred kilometers, these are completely two concepts of things, one is the near sea, ferries and simple boats can pass, the other is the ocean, only real sea ships can, it seems that the distance is 6 times more, but the actual consumption is at least ten or twenty times.

In other words, if the Ryukyus are unable to produce their own food, even if the Navy spends all its efforts to develop it, the development of the Ryukyus will only be average, and when most of the food needs to be supplied from outside, it is destined to be unable to supply more people at this level of transportation for the Navy.

For example, in the Ryukyus, if the industrial strength of the Dinghai Navy is reproduced, then more than 2 million people will be needed, and if it is expanded, 3 million or 5 million people will not be able to beat it.

600 people, even with the help of many agricultural machinery, it is impossible to completely develop the entire Taipei Basin, let alone the wider Ryukyus.

Ryukyu is mountainous, and most of the entire island is mainly mountainous, and there are also unique races such as the Takayama people, but there is also a lot of arable land, according to later records, about 8,000 square kilometers.

That is to say, of the more than 30,000 square kilometers of land, cultivated land accounts for about a quarter, and there are 12 million mu.

The first group of peasants to go to the island was only a vanguard force, and they would adapt to the environment of the Ryukyus and develop as much land as possible, and with the help of tools and the efforts of the Gaoshan people, it should be possible to complete the development of 100 to 150 square kilometers of land, so that the calculation is 15 to 200,000 acres of land.

These are enough, according to the average yield of 5.5 stone per mu, as long as 4 months, when the first batch of grain is planted and harvested, more than 1.1 million stone of grain, enough to support 200,000 to 300,000 people, then is the beginning of large-scale migration.

Preparations have already begun, and when these peasants arrive, every other month, the same number or even more peasants will come to the island, and once the scale of agriculture expands enough to bear large-scale migration, it will be the real moment for the development of the Ryukyus, and that time is not far off.

In addition to these agricultural personnel and agricultural machinery, there are not many other things, and the transportation volume of the entire fleet is about to reach its limit, and some daily supplies have been added, and this fleet will start again, and the expansion of the navy will also start from here.
