In terms of seed rate, 300 times the growth ratio, resulting in a high yield of corn, planting in the experimental field, with ordinary density calculation, this number is very amazing, even if it is cultivated in the experimental field, it has not been completely harvested, and I don't even know how much it is dry, but even if it is calculated at the lowest, 8 stone is certain, 10 stone is possible.

Hearing is false, seeing is believing, before this corn is not placed in front of you, no matter how you say it before, there is no truth that you have seen directly.

These first batch of corn agricultural experts came into contact with only then did they know why Zhao Xin spared no effort to promote the exploration of the Americas, which is thousands of miles away, even far away to the edge of the sky, is really a good place, even if it costs a huge amount of money for this, so that many people impeach and oppose it, they are unswerving.

In the thinking system of the Dinghai Navy, food is always the most important thing, and the entire Dinghai Navy, from the foothold, to the development, and then to the follow-up series of measures, to ensure the development of food, to ensure that the residents have enough food to eat, this is the most important thing, has never changed.

People have to eat, so that they will not panic, hungry people, anything can be made, in the time of famine, easy children and food abound, tiger poison does not eat children, let alone people, are all pro, why easy children to eat, isn't it their own children can't do it, in order not to starve to death, everything can be done.

In the research institute, some of them joined the Dinghai Navy at the beginning of the Dinghai Navy, and they were all at the bottom of the world, especially those who suffered misery in Lianghuai, they had already escaped, and they wanted to find a way to live, but could they really survive, all he asked for was so few opportunities.

If you stay here, you will definitely die, go out, and maybe you will be able to live, but this probability is very slim, some people have been affected by the disaster and escaped for a long time, not to mention Yizi and eaten, they have reached the verge of collapse.

Later, those who studied hard and joined the agricultural college were also able to increase their grain production and allow them to produce a little more grain, which for ordinary people, represented a reduction in the possibility of famine.

Over the years, Zhao Xin has been a huge investment in the College of Agriculture, and put forward a lot of theories, these scholars and experimenters, with great efforts, finally completed a lot of topics, not to mention, the entire Northern Song Dynasty's grain yield per mu, an average increase of 2 stones, is their efforts, and the navy itself, after occupying the Liao State, is directly used in the Northern Song Dynasty advanced experience, immediately let the Liao State per mu yield, from 2 stones, increased to 6.5 stones, this is more powerful than the Northern Song Dynasty.

It's a pity that this is already the limit, from 1 stone to 2 stones, and then to 3 or 4 stones, this promotion is easy, but when it comes to more than 6 stones, it is extremely difficult to improve without a little improvement.

For a student, it is relatively easy to go from 0 to 50, 50 to 70, it is not very difficult, but once it is higher, for example, if it reaches 90 points or more, it may not improve by one point, and the effort required is much more difficult than all the efforts before 70 points.

The agronomists of the Dinghai Navy, in such excellence, keep working hard, and pursue maybe one or two catties, or ten catties of improvement, there is a grain with such a large base, appearing in front of them, starting with 8 stones, the limit may be 8 stones, this grain production, directly let everyone down, some have had a tragic experience, and even think, if there were such crops a few years ago, or more than ten years ago, their tragic fate may not appear.

But soon, they came to their senses, stayed in the Northern Song Dynasty, not to mention whether there is such a crop, even if there is, what can it be, under the inherent class, they may be able to rely on this new food crop to achieve a full stomach, and the ability to resist risks is stronger, but the system does not change, they are destined to have no future, what about filling their stomachs, and how to resist natural disasters, if natural disasters exceed expectations, they still can't resist.

It is only when they come to Dinghai that they can develop steadily in this new system, or even in a special environment, from having no food and clothing to having enough food and clothing, being well-off, and even being rich, and only with sufficient foundation and savings can they withstand risks.

The emergence of corn is tantamount to letting the navy, on the basis of the original guarantee, add a layer, the land reclaimed by the navy itself, compared with the time of the Liao country, there is much more, and the grain output planted is also a lot, food security is guaranteed, and the corn is suddenly jumped to a catty and multiple times, which is more stable as a rock for food security.

Looking at the corn in the experimental field, it is becoming more and more mature, gradually approaching the corn of the harvest season, and at the same time, in some other experimental fields, it is also planted, a little later corn, these corns, and these are about to mature, forming a little difference, ranging from 10 days, to 20 days, 30 days, but the same rise is gratifying.

On the American continent, the area of corn cultivation is very large, after the initial acquisition of a few tons, and subsequently, along with the exchanges with the Indians, especially through some exchanges, a considerable amount of corn was obtained, at least about 50 tons.

This is more than 10 times the amount originally shipped back, if it is placed in the experimental field, it can be guaranteed to be planted for a long time, and the planting area is expanded to 300,000 mu, which is no longer experimental planting, it is a certain large-scale planting.

Not to mention the multiplier of 300 times, even if it is 120 and 150 times, the average yield per mu of 9 stones, the final output may be 2.7 million stones, that is, 270 million catties.

If 7 catties of land are planted per acre, 40 million mu of land can be guaranteed, which is already a fraction of the cultivated land area of Liao, and the purpose of promotion is basically achieved.

In fact, there are not so many of them, and these corn have been transported back to China one after another, and they have not encountered any danger, and they have all been successfully transported to the Dinghai Navy, and there has not been a little incident, but it is not quite in season, and it is impossible to plant them all.

Planting grain needs to be planted according to the time of day, and if it does not depend on the time of day, the yield will be reduced, and the grain will not be harvested at the worst, even if the income is high, it is unacceptable that the grain will not be harvested.

Except for a few areas, most of the areas should be in high latitudes, and after entering September, the outside temperature is already extremely low.

Corn characteristics are very good, drought resistance, but it is impossible to survive in the wild land of eastern Liaodong in winter, these have been transported back to China, except for a small part in the second batch, the third batch of planting, so that the number of corn in the experimental field, increased to 18,000 acres, there is no more planting, only a small part, placed in the laboratory constant temperature field, a series of experiments.

In the past few years, Dinghai has laid the foundation of science and technology, and also formed a set of agricultural science and technology research, which has been applied to the breeding and cultivation of corn one by one, further judging some characteristics of corn, and strengthening Dingjun's understanding of corn.

The planting plan that Zhao Xin came up with, of course, is the 21st century, after years of cultivation, summing up experience, and finally forming the planting technology, to say that there is no problem at all, it is also a lie.

Not to mention the gap between thousands of years, the gap between seeds, the degree of industrialization, and the in-depth research on chemical fertilizers for pesticides, this point, the Navy is greatly inferior, maybe the planting method can be compatible, but there will definitely be some omissions, or deficiencies, which need to be gradually run in by the Institute, and even make adjustments and modifications.

Just a few months of planting, the yield of corn, has shocked everyone, as for its characteristics, for example, drought resistance, as well as in high latitudes, as well as the advantages of planting in the north, these all show the terrible corn is terrible, not to mention, his taste, is also very good, the use of considerable diversity, it can be said unceremoniously, huge investment, after the corn was found, after returning to China, has earned back, this is a long-term planting, and for food, there is a huge supplement to the crop.

Even the laboratory personnel thought that this was already the limit of corn, Zhao Xin came up with a new task half a month before the first batch of corn was about to be harvested, that is, to study how to make comprehensive use of corn stalks, and also put forward some plans, for example, the use of corn stalks, to make feed, for breeding.

In Dinghai, from the beginning, when the beginning of the development of breeding, has put forward the method of green storage, although it is said that ordinary grass, can also be green storage, but among all the things that can be stored green, corn is the most suitable, corn, rich in a variety of substances, through the green storage, reduce harmful things, increase the beneficial things, and finally get out of the things, is the most suitable feed, for feed, the efficiency is very high.

To be honest, before this, the whole institute was attracted by the high yield of corn, and he didn't notice it at all, not to mention the yield of corn itself, just the plant, the corn plant is also very terrible, a corn seed, can grow into corn like a small tree, the growth efficiency is very terrible.

Green storage, as well as the study of feed this topic, once it was raised, it immediately caused a sensation, although it is said that the corn is not fully mature, but in the laboratory, there are some mature, at the same time, the study of plants, small batches, can not wait for maturity, the immature plants are also taken into account.

First of all, of course, it is the Qingchu, which is the most mature method used by the Dinghai Navy, and it is also the most widely used method, which began to be tried long before taking the Western Xia, and after that, the large-scale promotion in the northwest of Han Qi has produced great results, and the northwest can lay the foundation for the current breeding, and the Qingchu has played a great role.

Later, after the Dinghai Navy took the Liao State, the green storage was really applied, which can increase the utilization efficiency of forage grass and can be stored for a longer time, which is stronger than hay, and has a very good effect on the wintering of animals.

It is precisely because of the huge effect that in the Animal Husbandry Research Institute, the research on the green reserve has never stopped, and Ding Haijun is also very familiar with the green reserve, which is nothing more than using a certain temperature and humidity to ferment these plants and grow more and easier for livestock to digest the feed, so as to improve the efficiency of breeding.

Corn is natural, is the standard of feed, many feed mills in later generations, most of them are using corn plants to produce feed, such feed is inexpensive, and it is also good for the growth of livestock.

A little green storage, you can, these very mature things, and corn is simply a perfect match, this as long as this is made according to this, the final data in all aspects, are very perfect, is the best source of feed.

Feed, this is the real effect of corn, grain is only a part of it, feed is the end, I thought that the effect of corn, will only be the role of food, but I did not expect that there is such a feed, this time, enhance the comprehensive use of corn.

With this, the comprehensive effect of corn should be far more than wheat and rice, which is the key to the final promotion, and these are all the uses of corn.

The method of green storage feed is very simple, and even before, in the northwest, in the grassland of the current Dinghai Navy, there is also an application, and a considerable method has been summed up, and after the full use of it, the corn will soon be used for feed.

Relative to corn, the weight of corn stalks is greater, the general output is about 3 tons to 3.5 tons, not to mention the comprehensive utilization and production of feed, just say the simplest green storage feed, even if there is no mechanical equipment, a family can carry out, after a period of green storage fermentation, the overall weight will be reduced by 10% to 20%, that is to say, in this sense, not to mention the output of corn itself, an acre of corn, can produce 3 tons of feed.

This is an extremely terrible number, according to an ordinary cow, 32 kilograms of forage per day, as long as the green storage feed is used about 18 to 25 kilograms, the saving is about 40%, but the effect will be better.

In this way, the consumption of a cow should be more than 9 tons in a year, that is to say, after 3 acres of straw storage, a cow can be fed.

After this number came out, the person in charge of the research first felt that the number could not be calculated wrongly, but all the records were made in the most scientific way, and even the cattle were eaten for a month, not only did they have no problems, but they also grew meat, and the effect was very good.

Knowing that corn stalks can be used as feed, but after the green storage, the number is so large, the effect is so good, they absolutely did not expect, in this sense, in the eyes of everyone, the role of corn has been improved again, before it was already a strategic height, and now it has reached the level of pricelessness.
