On the eighth day of Zhang Jun's death, the Zhang family finished the first seven, according to the customary ordinary lord should be buried in his hometown, the coffin went out of the city on the same day, the king of Xian took dozens of people to see him off in plain clothes, and allowed him to go around the palace wall and return to Dingyang through the north gate, for which a four-wheeled carriage was also prepared as a temporary carriage to transport Zhang Jun's coffin back to Dingyang City.

At noon on the same day, the newspaper published a supplement, praising the merits of the Marquis of Ding Yang from a fair standpoint, and giving him the nickname "Mourning Wu", but the full text did not mention anything about the events before 630.

On the ninth day of the first month of May, the prince stayed in the tomb to preside over government affairs, Bailiyan, Lu Gao and others accompanied the king of Xian on patrol, the team walked slowly, inspected the growth of crops and the people's sentiments along the way, and worked hard for many years, and the effect of the new policy gradually penetrated into the grassroots, and the results became more and more significant.

In the carriage, looking at the rice fields growing happily outside the window, King Xian said to Bailiyan:

"Such an acre of paddy field, in the summer, there will be a harvest of three stones."

"Back to the king, at least four stones, the current yield per mu of the capital county is basically between four and five stones, and the fields in Wuping can reach seven stones, and even the latest good varieties, and the high-yield ones can have nine stones."

King Xian smiled and nodded, and after a moment of thought, he said:

"Can the yield per mu of counties outside the capital county also have four stones?"

"Some have, some don't. Most of the prefectures are guaranteed to be 4 or 5 koku, and 1/2 of the prefectures are between 3 and 4 koku, and the situation in the rest of the prefectures is different.

For example, about 20% of the land in Beihai County can produce 4 stone of rice, 50% of the land can get 3 stone, and the rest hovers between 2 and 3 stone, while most of the new four counties are less than 3 stone, and a few are more than 3 stone.

In addition, the promotion of the new policy in Jiangdong and Suidang counties is unfavorable, and farmers lack the willingness to grow grain, and there are almost few yields of three stones per mu, and most of them are less than two stones. ”

Hearing this, King Xian's eyes sank, and he clenched his fists and said:

"When will the agricultural policy of the capital be promoted to the whole country?"

"It's not easy to say, the reason why the grain production of the capital county is so high, one is that the breeding is good, the second is the accumulation of fertilizer, and the exploration of the open sea has found that there is a natural good fertilizer, and the eldest grandson produces volcanic soil, which is also an excellent fertilizer, and the ministers ordered a large number of people to transport it back and mix it with straw ash and sell it to the farmers, and the grain production of the capital county depends on this kind of fertilizer.

Not only is the material less, but also the fertility is retained in the field for a long time, and the human and animal fertilizer is used together, only a small amount of input can be used to reap the effect of two or three years. But it is still a bit difficult to promote it to the whole country. Especially the volcanic soil, which is only produced by the eldest grandson, and the minister ordered someone to steal it, so he can't get too much back at a time. ”

Hearing the news that Baili Yan was stealing fertilizer from his eldest grandson, King Xian was surprised and hurriedly asked:

"Does the eldest grandson know the mystery?"

"The king can rest assured, no one in the world knows the benefits of this volcanic soil, and he has lived under the volcano for a long time, and there are eruptions and earthquakes all year round, so people are afraid, so the eldest grandson country plays a role in billions of wealth, but does not know the benefits.

However, the king does not have to worry about grain production, Beihai, Dongyuan and Xianbei Northwest, Jiangdong County and coastal areas, are successively promoting three crops of rice, the next year can be planted three seasons, even if there are only two stones per mu, six stones of rice can be harvested a year, if it is three stones per mu, one mu is nine stones and ten stones a year.

And Qiunan and the new four counties, in autumn and winter, can be used to plough a large number of winter wheat, and in a few years the harvester is used in large quantities, one person and two cows, a day can harvest ten to twelve acres of wheat or rice, if it is not a year of great disaster and famine, the people will no longer worry about eating and drinking. ”

"Well, if the people of the widow do not worry about food and clothing, the widow will not go through this life in vain."

"Hehe, the king's wish is too low, but there are other new problems without worrying about food and clothing, such as a large increase in grain in the future, the price of grain will drop sharply, and such a cheap price will hurt the people.

According to Chen's calculations, in 30 years, even if it is a thin field, the yield per mu will reach a minimum of four or five stones, and twelve stones of such an excellent land as Wuping may not be unexpected, and by that time, the price of grain will fall to half to two-fifths of what it is now. ”

As he spoke, a flying insect broke into the car window and hit King Xian in the face, and King Xian was shocked:

"The little bug actually bullied the head of the widow, hehaha......"

King Xian laughed, and Bai Liyan answered:

"This is a worm, whose name is 'Grass Leaf Fly', and it is a good insect that specializes in eating crop pests."

"Oh, insects are good and bad like people?"

"Insects are not absolutely good or bad, compared to people, those who eat crops, poisonous insects are pests, but for insects that eat insects for a living, some pests are food."

"Aiqing's words, but it reminds the widow that a few years ago, the countries have had insect plagues one after another, and the widow remembers that there was a report last year, and there was an outbreak of insect plague after the summer planting in the land south of Qiu Nan and Suidang bordering Zhiguo, and Aiqing should pay attention to it."

"Please rest assured, the minister has been properly dealt with last year, and the insect plague will never spread to my hinterland this year. The minister is worried that if all countries do not pay attention to the insect plague, there will be progress and the threat of instability in the Central Plains, which will affect the supply of China's trade materials, and then indirectly harm China's interests. ”

The insect plague has always been a big problem, since the locust plague swept the Central Plains more than 20 years ago, the locusts have left a deep shadow on this generation, affected by this, the public sentiment intensified, and the black towel was able to flourish.

After several years of good times after the promotion of the new agricultural policy in Xianguo, there have been small-scale insect plagues, which affected the harvest, when the chemical industry was not yet developed, and pesticides could not be used, Baili Yan had to find another way, using biological control methods, to control crop pests.

Through the cultivation and breeding of a large number of pests natural enemies beneficial insects, regular fixed-point release of a large number of animals, supplement the ecology, and at the same time breed peregrine falcons, spotted herons and other insectivorous birds to kill insects. Due to its location in the north, the winter temperatures are high, so many birds do not need to overwinter, but there is no need to worry about these birds migrating and flying away.

In addition, Bailiyan also has a big killer, the "Black Feather Gong Chicken" brought back from Qiu Bigong, this chicken has strong adaptability, can eat cockroaches, millipedes, longhorns and other medium and large insects, and also eats locusts.

Because it is a pheasant, it can fly more than 10 meters high. There are a large number of breeding farms throughout the country, which can be released in large quantities intensively when necessary to extinguish locusts. Combined with other control methods, in order to achieve the purpose of reducing insect infestation.

After years of governance and institutionalized operation, the effect of biological control is not worse than that of pesticides, and the economic cost and social comprehensive cost are cheaper than pesticides.

Although there are shortcomings such as lag and insufficient biological populations in biological control, pesticide control will bring more serious food chain pollution, the burden of social medical costs brought about by the increase of malignant diseases, and even the emergence of drug-resistant insects, which is undoubtedly a greater harm to the geographically connected Central Plains countries.

So today, even though it has the capacity to produce pesticide chemicals, Bailiyan is still very cautious.

Last year, the insect plague that was introduced to Xianguo through Zhiguo was reported to the imperial court as soon as possible, and Bailiyan immediately released insects and birds in the local area, so as to establish a barrier to curb the spread of pests to the north, and at the same time increase the release of insects into the hinterland, so as to speed up the formation of a protective barrier in the hinterland.

Wang drove all the way to stop and stop, on May 12 received an urgent report from the border pass, the patriotic envoy Lu Jia and two days ago landed in Ganfu, was hurrying to the Lingling, the king of Xian ignored it, the itinerary remained unchanged, the car arrived at the mausoleum in the south of Miaotian Mountain on May 13.

Mausoleum in the month, including the burial goods and the sealing of the soil backfill and other work is fully completed, the surface building is basically completed after the autumn of this year, the building atmosphere is exquisite, the craftsmanship is solemn and elegant, the temple, the public hall, because it is located on the prime meridian, the center of the mausoleum erects the "meridian obelisk" of five zhang high

A hundred years later, King Xian will set up a stele under the obelisk, and set up an incense case for future generations to pay homage to. If there is no accident, after the Xian State unifies the Central Plains, the mausoleum of Jiang Hai, the king of Xian, will become the imprint of an era.

After staying in the mausoleum for three days, King Xian inspected the surrounding terrain and proposed to wait for Miaotian Mountain to observe the sky, and return to Ruitian, Wuping, and Xuanyun on the 17th to inspect production and education.

After several years of operation, Ruitian has built a large number of government-run enterprises, and with the approval and support of Bailiyan, individuals from Yongxing City and clean relations are allowed to use the accumulated capital and interest-free long-term loans provided by Bailiyan to open private private enterprises to fill the market demand.

At the same time, they are allowed to seek the development of other blank industries or technical fields by themselves, and encourage them to put forward technical requirements, feedback to the Technology Agency, and after demonstration, if the technology is feasible, the government can first advance funds to manufacture sample machines, so as to encourage private technological inventions, and can obtain the protection of the patent law.

Xuanyun moved in place last year, and it has been less than a year since this year, and it is still in the transition stage, and there are not many people, but the local academic atmosphere is strong, and King Xian stayed here for three days, during which he met with representatives of various factions and outstanding talents in the professional academic field, and also asked a lot of questions. Especially in the field of medicine, he even asked Jiang Can about the topic of immortality at one time.

However, this dream that human beings in ancient and modern times, China and foreign countries, and even different time and space have been tirelessly pursuing, is still unrealizable today, let alone the present, when the earth's life sciences are highly developed.

But fortunately, the current ecology is intact, a large number of rare animals and plants have been preserved and continued, and more medicines can be obtained.

In the case of the ice velvet flower, its powerful effects are almost beyond the reach of any medicine in the plants known on the planet, and if it were not for the ecological damage caused by human overexploitation and social development, more species would have been spared destruction.

The diversity of biological populations brings more room for choice, more drugs to improve the quality of human health, and it is entirely possible to prolong life expectancy, Xianwang and the domestic elite class are excellent typical representatives, including Xianwang, the average life expectancy has reached more than 60 years old, and even 70 years old, which was almost unimaginable 30 years ago.

You must know that the quality of life of the elite class is not worse than that of modern people, food, clothing, housing and transportation are extremely exquisite, in addition to the dishes are not enough, regardless of what tricks Bailiyan has made, the current aristocracy is not less involved in meat, protein, and oil than modern people, and the current medical conditions are much worse, under the huge gap, the powerful and wealthy classes are more likely to suffer from the three highs and malignant diseases, so most of the life expectancy is not long.
