At the same time, Liu Xin didn't know that Jia Xu, who was far away in Liangzhou, was already planning to take refuge in himself, otherwise Liu Xin would definitely jump up excitedly. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

In fact, Liu Xin has long lost confidence in recruiting Jia Xu, because Jia Xu is a smart person in Liu Xin's opinion, and he is proficient in protecting himself and will never stand under a dangerous wall.

So when Liu Xin exposed his ambitions in front of Jia Xu, Liu Xin felt that Jia Xu would choose neutrality nine times out of ten, that is, after the Taiping Dao really launched a rebellion, he would not necessarily come to take refuge in himself, but he needed to come out in person and ask Jia Xu to help him.

At this time, Liu Xin was talking to Su Jia about how to choose crop seeds.

First of all, Su Jia expressed her approval of the poppy seeds selected by Liu Xin, because this is a high-quality raw material for making sedatives, and Su Jia has always had no way to make sedatives because there are no suitable raw materials.

You must know that sedatives are Su Jia's most important attack methods, to be precise, one of the ways to counterattack, because Su Jia, as a future intelligent robot, is written into the code when it is produced and set up, and it cannot harm humans.

However, it is also to protect the self-interests of the robot and the rights and interests of the robot owner, and to prevent some idle people who have nothing to do to deliberately attack the robot, so the robot is allowed to use non-lethal and minimal damage when it is attacked or threatened by life.

Among these counterattack methods, there is the electric shock method used by Su Jia before, and Su Jia's electric shock is actually a kind of massage therapy, which can make people feel relaxed, numb and crispy all over the body, and have a fluttering feeling.

Of course, this feeling is like a nightmare for those thieves who broke into Liu Xin's mansion in the middle of the night and wanted to do something unsightly, and they were a little weak-hearted, after all, they suddenly felt like they were electrocuted, which was enough to make them fall into an ice cave, thinking that they would be electrocuted here.

Su Jia also has a way to fight back, that is, to release itchy powder, which can make people itchy and unbearable, of course, the packs of itchy powder that Su Jia gave Liu Xin at that time were processed and upgraded, and ordinary itchy powder does not have such a powerful effect, but after all, it is not Su Jia who uses itchy powder personally, so it is not against the relevant regulations to make itchy powder with strong effect.

The sedative is another way for Su Jia to fight back, using a highly purified version of the sedative made by special techniques, which can be directly shot into the human body at a very fast speed through the high-pressure jet gun in Su Jia's fingers, so as to quickly exert a sedative effect, which is also a counterattack method often used by intelligent robots in the future when they are responsible for security work.

However, Su Jia has been working in the research institute of the future, and it is strictly classified as an experimental assistant robot, and there are also intelligent robots in the research institute that are specifically responsible for security, so Su Jia is not equipped with sedatives.

But in the troubled times of the Three Kingdoms, in order to protect herself, in case someone attacks Su Jia, Su Jia can only use passive counterattack to protect herself due to the restrictions of her own rules, so at this time, Su Jia can have one more way to counterattack, and the situation will be better, so Su Jia decided to configure a suitable sedative.

No, in the list of sedative preparation materials stored by Sujia itself, the sedative ingredients extracted from the opium poppy are the best material and the most suitable material.

However, as mentioned earlier, the original factory of the opium poppy is not in Dahan, and it will have to wait at least a hundred years for the poppy to be brought into China as a flower by those Hu merchants from the Western Regions.

Although Su Jia can still afford to wait, after all, as an intelligent robot from the future, Su Jia has not been seriously injured, such as jumping from a mountain hundreds of meters high and landing directly, staying in a strait hundreds of meters deep for more than ten or twenty years, and jumping into an active volcano...

All in all, as long as there is no accident, Su Jia can almost be said to be longevity and Tianqi, and when the corresponding parts are damaged, Su Jia can also make suitable low-profile parts for replacement.

But to tell the truth, if you really have to wait until a hundred years later, then Su Jia will not need sedatives for a long time, after all, Liu Xin has already unified the world at that time, and Su Jia is already a high power, and when she is attacked, Su Jia has guards around her.

However, it is also important to note here that sedatives are not anesthetics and are fundamentally different from anesthetics.

Sedatives are a chemical agent that is specially used to reduce the function or activity of a certain part of the body, and sedatives help to relieve people's depression and anxiety, so they can also reduce people's aggression to a certain extent, so as to achieve the effect of surrendering without a fight.

In the field of modern medicine, sedatives are used in many aspects, of course, they are usually used to treat patients with mental stress, and sedatives are conducive to relieving patients' nervous emotions, and taking sedatives correctly is beneficial to health, and it will not be as some articles forwarded by WeChat Moments say, the use of sedatives will affect normal brain activity, thereby weakening the user's ability to use the brain.

Of course, sedatives can not be used blindly, for example, barbiturates, as a sedative-hypnotic drug, have poor safety, and often appear poisoning, and are highly addictive, so in recent years, sedative-hypnotic drug addiction and abuse have become one of the serious social problems in many countries.

Therefore, barbiturates were gradually replaced by drugs with low dependence in terms of sedation and hypnosis, and soon after the advent of methamphetamine, barbiturates were eliminated by some countries (including China, of course).

Moreover, if sedatives are used blindly, the consequences include damage to cognitive motor function.

So the tranquilizers are like the poppy, which is the raw material, half angel and half devil, depending on how you use them.

As for why Liu Xin knows so clearly, because an author surnamed Liu, who did not want to be named, almost failed the course because of this sedative during college, so Liu Xin had a profound impact on this.

Therefore, in the discussion between Liu Xin and Su Jia, they took the lead in deciding on the first crop seed - opium poppy.

Because he was still in Luoyang, there was no place for Liu Xin to grow poppies, so Liu Xin decided to wait until he returned to Yizhou to exchange the seeds.

As for the second crop seed, Liu Xin and Su Jia also talked for a few seconds before making a decision.

At that time, the conversation between Liu Xin and Su Jia was like this.

Liu Xin: "I think we can exchange the seeds of hybrid rice. ”

Su Jia: "Well, hybrid rice has a very big effect on us, not only because it has a high yield, which is conducive to promotion, but it is also a good material for winemaking. ”

As a result, Liu Xin and Su Jia decided on the second crop seed, hybrid rice, which is the series with the highest score in Tiandao.

As the origin of rice, the Chinese people's rice planting and cultivation history has been 14,000 to 18,000 years, and in the 5,000 years BC, the Yangtze River basin in China began to plant rice on a large scale, which also marks that the Chinese nation has become an agricultural civilization, and legend has it that after Yu ruled the water, he ordered his people from various tribes to start planting rice.

According to different classification methods, today's rice can be divided into indica rice and japonica rice, early rice and middle and late rice, glutinous rice and non-glutinous rice.

Rice is the fruit of rice, rice is called brown rice after removing the glume husk, brown rice can be obtained by grinding the rice bran layer, nearly half of the world's population is now fed on rice, this is because there are various ways to eat rice, there are rice, rice porridge, rice cakes, rice cakes, rice wine, etc., too many to list (of course, this is also because of the foodie attribute of Chinese civilization).

And in addition to being edible, rice can also be used for winemaking, sugar, rice husks, rice stalks, can be used as feed for livestock, so it can be said that the whole body is a treasure, so in various periods of China, the planting of rice has never been interrupted, and the harvest of rice every year also determines whether this year is a good year or a disaster year.

However, the locust plague is very fatal to the rice attack, because rice is an annual plant, summer and autumn have a decisive role in the growth and development of rice, so if a serious locust plague breaks out at this time, then the rice fields in this area can be said to have no harvest.

And now the rice planted by the Han Dynasty is still relatively low-yield native rice, of course, there are also fertilizers and cultivation methods, according to the relevant records, the yield of rice per mu in the Han Dynasty is only three stones, which is converted into about 250 catties in modern times.

At the same time, the yield of other grain crops in the Han Dynasty generally exceeded three or even four stones per mu, so the price of rice in the Han Dynasty was relatively expensive, and even some ordinary officials could not eat rice every day.

The first major event that changed the history of rice cultivation in China was the introduction of Champa rice in the Song Dynasty.

Champa rice is a high-yielding, early-maturing, drought-tolerant rice variety native to the Indochina Peninsula, which was introduced to China during the Song Dynasty and quickly spread in the Jiangnan region.

Cham rice is named after its place of origin, located in the south-central part of present-day Vietnam, and Champa rice, also known as Zaohe or Zhanhe, is an early indica rice that was first introduced to the Fujian region of China in the early years of the Northern Song Dynasty.

According to ancient Chinese records, Champa rice has many characteristics - first, it is "drought tolerant"; the second is strong adaptability, "born regardless of location"; Third, the growth period is short, only more than 50 days from planting to harvesting.

The emergence of Champa rice completely changed the pattern of grain cultivation in China, rice officially became the most important food crop in China, and the planting range of other food crops became smaller and smaller, and even millet, sorghum and other food crops that could once be called rice were also officially called miscellaneous grains, which were distinguished from rice.

Of course, in the history of rice cultivation in China, the most important event occurred in the 21st century, and the greatest invention in the history of human planting - the successful research of hybrid rice!

Hybrid rice is to select two rice varieties that have certain genetic differences, and their excellent traits can play a complementary role, and after hybridization, the first generation of hybrids with heterosis is produced, which is hybrid rice.

Heterosis is a common phenomenon in the biological world, and the use of heterosis to improve the yield and quality of crops is one of the main achievements of modern agricultural science, so all kinds of vegetables and grains we eat now are basically cultivated through hybridization.

Rice has obvious heterosis phenomenon, which is mainly manifested in vigorous growth, developed root system, large panicle and many grains, strong stress resistance, etc., therefore, the use of rice heterosis to greatly improve the yield of rice, which has always been the dream of breeders.

However, there is a problem in front of all breeders - rice is a self-pollinating plant, the male and female stamens are born in the same spikelet, because the spikelet is very small, and each flower only bears one seed, so it is difficult to produce a large number of first-generation heterogeneous seeds by artificial de-emasculation hybridization, so the heterosis of rice has not been applied for a long time.

With the unremitting efforts of our scientist Yuan Longping, we finally developed a three-line super hybrid rice (as for the three lines, I don't know too well, but I can Baidu by myself), so that the yield of hybrid rice per mu has reached nearly 1,000 catties, which is four times higher than the current rice of Dahan, and if the annual yield is calculated, the hybrid rice can be said to be more than ten times that of Dahan rice!

According to the analysis of Tiandao, as long as it is carefully managed, to ensure fertilizer, do not encounter pests and diseases, that is to say, in the most ideal environment, this hybrid rice can be harvested twice a year in the southern region of Dahan (that is, south of the Yangtze River), and the yield per mu is about 1,000 catties!

Liu Xin knew that he had picked up the treasure again, and as long as the hybrid rice with a yield of 1,000 catties per mu was successfully promoted, the probability of famine in Dahan would plummet.

The most important thing is that the seeds of this hybrid rice can be exchanged for the full amount of 10,000, which means that the time for cultivating seeds will be shortened by a few ******s: the first watch, today will be the third watch, but the time of the second and third shifts is uncertain.
