Zhu Yijun took the ministers to his nursery room, at this moment, he stood in the light, let Daming be great again, starting from the nursery room.

Zhu Yijun led his ministers to a container full of water, which was a somewhat oddly shaped device.

It was only half a foot in size, and at the bottom was a glass bubble the size of an egg, and the glass bubble was soaked in water, and on top of the glass bubble was a finger-thick glass tube, and on top of the glass tube was a wooden cork, and a thin glass tube was inserted into the wooden stopper, about three or four needles thick.

The entire installation is filled with water, and the thin glass tube above the wooden stopper is marked with scales.

"This is a thermometer, which is specialized in measuring temperature, and I have people record the temperature of the glass bubble soaked in the ice-water mixture, and measure the height of the water surface in the slender glass tube, which is recorded as 0; The glass bubble was soaked in boiling water, and the height of the water surface in the slender glass tube was measured, which was recorded as 100. It is then divided into 100 equal parts. Zhu Yijun introduced his first gadget, measuring temperature.

This device is extremely simple, but it is already the best thermometer that Zhu Yijun can do in the first year of Wanli, he can't record the temperature below zero, because the sub-zero water will freeze, freeze and crack the test tube, this device is temporarily enough, if there is a high concentration of alcohol in the future, you can replace the glass soaked water with alcohol, and try to measure the sub-zero temperature.

Zhu Yijun didn't think of mercury, that is, mercury, this thing is not lacking in the royal family, but Zhu Yijun did not have a good way to solve the problem of mercury volatilization, mercury vapor not only poisoned people, but also may cause harm to seedlings.

For the research and development of thermometers, Zhu Yijun will not stop, but he will also move forward step by step.

This inaccurate thermometer records the temperature of potatoes and sweet potatoes turning green and germinating in detail, which provides a reference for the planting of potatoes and sweet potatoes in the north, and can also be reasonable to follow when promoting potato and sweet potato planting in the future.

The fire room is the nursery room, there is also a thermometer outside the fire room, Qingming is coming, the potatoes begin to germinate, the control group outside the fire room, under the two corresponding, Daming got the budding temperature of the potato sweet potato five to eight degrees, the sprout is the sprout, only when the temperature further rises to about fifteen degrees, it will thrive.

Zhu Yijun talked eloquently to the ministers, introducing the harvest of the glass fire room nursery room.

Ge Shouli's jaw was about to fall in surprise, he looked at it in a daze for a long time, and said sluggishly: "Your Majesty's whimsical ideas are really ingenious. ”

Thermal expansion and cold contraction is not unusual, as early as the pre-Qin period, Li Bing and his son used thermal expansion and cold contraction to open mountains and crack stones, but the use of this thermal expansion and cold contraction to this extreme is completely whimsical, and the craftsmen of the Ming Dynasty have realized the whimsy of the little emperor.

In fact, this is a degree bypass, which is mathematical thinking to be exact.

The thermometer is just a small design of his, and in the fire room of more than half an acre, there are thousands of small boxes with glass lids, each of which has a seedling, and these seedlings are lush and look full of life.

"Master Xu." Zhu Yijun shouted and motioned for Xu Zhenming to introduce these small boxes and what they do.

Xu Zhenming didn't expect that His Majesty the Emperor would bring the Ming courtiers to visit, he was not prepared at all, when the emperor called him, he was still observing the situation of the seedlings, he turned around blankly, and hurriedly came to everyone, only to remember, to salute the emperor.

"This is a seedling, pinch the tip, the tip..." After a period of scramble, Xu Zhenming was stuck, he was unprepared, so he didn't know how to make a summary at all.

Zhu Yijun looked at Xu Zhenming's honest appearance, but he was not angry, he could speak well on weekdays, let him behave, and he would not be useful if he was given a chance.

Zhu Yijun interrupted Xu Zhenming's words, motioned for Xu Zhenming to step aside, or he would have answered, he said with a smile: "This is a seedling box, water chestnuts, potatoes, sweet potatoes, these crops that are planted with tubers, accumulate toxins from generation to generation, resulting in lower yields from generation to generation, how to detoxify?" ”

"The old farmer who planted water chestnuts told me that if you pinch the tips, pinch the tips down and plant the seedlings, the yield will be much higher, and the seedlings on the left hand, each plant is pinched and then sent to the fire house over there, and after 15 days of growth, it will be taken out again."

"The soil in this seedling box is all soil after steam fumigation, which is to prevent poisoning of the tips pinched out."

Zhu Yijun did not enter the fire room, the temperature inside is about 38 degrees to 40 degrees, this is high temperature passivation, this is Xu Zhenming's idea, in fact, it is the finishing of the green tea production process, green tea in the preparation process, in order to stop the fermentation of green tea, it will be finished through steaming, blanching, drying and other methods.

Xu Zhenming thinks that it is all poison, can it be reduced by finishing the drug?

However, when the temperature is high, the seedlings will die, and when the temperature is low, it is useless.

Xu Zhenming succeeded, the new seedlings grown in the seedling box were fuller than the old seedlings outside that had not been finished, and there were no yellowing, ulceration and other diseases, which made Xu Zhenming particularly excited.

Zhu Yijun took a box of seedlings from the seedling box, and picked up another box, this box was not finished, that is, the seedlings that had not been passivated by high temperature, lifted it up, and put it on the table, the little emperor said with a smile: "The difference is huge." ”

The courtiers pointed around the two seedling boxes, and there were many discussions, the little emperor personally worked on agriculture and mulberry, and actually made so many results, looking at this posture, he really planned to plant it, instead of showing off and pretending.

The courtiers also thought that the Baoqi Hall of the Ming Emperor was just a symbol of the emperor's emphasis on agriculture and mulberry, even if it was harvested, there was not much harvest, and the eunuchs of the ceremonial eunuchs would not buy it? Plant the potatoes and sweet potatoes you bought in the ground, and when it's time to harvest, shout auspicious?

Song Renzong's Baoqi Palace, Qi is two, that is, two ears of wheat are planted on a wheat, which is regarded as auspicious.

When Song Renzong, those eunuchs in order to please the emperor, collected double-headed ears of wheat from the people, and secretly planted them in the field in front of the Baoqi Hall of Song Renzong at night.

The courtiers of the Ming Dynasty are all involved in the position of the Ming Duke step by step, and everyone is a fox for thousands of years, of course, this trick can be seen through.

Therefore, in the eyes of most courtiers, the matter of family affairs is just a copy of Song Renzong [Qi Mai Xiangrui].

It's just to fool the emperor, the ministers fool the emperor, aren't the eunuchs fooling?

To the surprise of the courtiers, the Ming Emperor didn't play this trick and played it himself! And the two boxes in front of me are placed in the sun, and the difference can be seen at a glance, which is the result of personal practice.

Zhang Juzheng and Xu Zhenming were talking on the side, most of them were Xu Zhenming talking, and Zhang Ju was listening.

Xu Zhenming mainly talks about what the little emperor does, nine out of nine heavy work is tiring, before the little emperor comes to the Baoqi Palace, Xu Zhenming has arranged for people to do it, only a little bit of work, after the little emperor learns martial arts, he will deliberately leave it to the little emperor.

It's not dangerous, it's not dirty, it's not tiring, and it's very engaging.

"Does Your Majesty come over every day?" Zhang Juzheng asked a very strange question.

Xu Zhenming didn't know why Yuanfu asked like this, he said quite accurately: "It rained the day before yesterday, and Your Majesty also came, and Your Majesty came every day." ”

Zhang Juzheng held his hands, clenched his fists, and looked at the back of the little emperor, the little emperor is not messing around, and he has no intention of giving up halfway, Hongyi, with the world in mind and perseverance, is Mingjun, is the lord of virtue, and is a warrior.

Zhang Juzheng has it for the first time, and the re-emergence of the Ming Dynasty is not a feeling of being in the mirror, this feeling is extremely certain and real.

"You did a good job, this is the waist card of the Quanchu Guild Hall, don't lose it if you take it, and don't lend it to others, in the future, if you have something to look for me." Zhang Juzheng picked up a waist card from his waist without a trace and handed it to Xu Zhenming.

"Xie Yuanfu appreciates!" Xu Zhenming was extremely surprised, and bowed to Zhang Juzheng's door, it was not silver, but also ability, and it had to be related.

To this day, Xu Zhenming doesn't know why he was recommended by Zhang Juzheng to be a bachelor by the emperor, and now he is even under Zhang Juzheng's door.

Zhang Juzheng said gently: "Bing Jing, carbon respect, you don't have to think of a way, you don't have that way, do things well by Your Majesty's side, plant the land well, and never let anyone destroy Your Majesty's agricultural affairs, whether it is a eunuch, a horseman, a guard, a person with a knife or an old farmer, absolutely not." ”

Zhang Juzheng knows that some people don't want to see the emperor get great results from farming, if they play the trick of [Qimai Xiangrui], no one will stop it, but the emperor does it himself, and he really wants to grow results, and some people will be unhappy and will make a hindrance from it.

Because if there is a result, it will consolidate the foundation of imperial power.

Xu Zhenming is actually not good at drilling, let alone corrupt and perverting the law, twice a year filial piety, to two thousand taels of silver, Xu Zhenming is a Jinshi with a bamboo strip bookcase, where to find two thousand taels of silver a year for filial piety?

Zhang Juzheng exempted him from filial piety, as long as he did what he did best, farmed, and was optimistic about the ten acres of land.

Planting potatoes and sweet potatoes well can really yield more than 1,000 catties per mu, and the weak state affairs of Daming can also increase a little vitality.

Zhu Yijun glanced at Zhang Juzheng and Xu Zhenming, and did not say anything to stop it, let alone interrupt, Xu Zhenming wanted to do something, he had to worship someone's name, Zhang Juzheng was willing to accept it, it was Xu Zhenming's opportunity.

Come out to mix, you have to talk about strength, but also about power, at least for more than ten years, Zhang Juzheng is the biggest backer of the Ming Dynasty.

Zhu Yijun pointed to the roots in the seedling box and said: "There are a lot of particulars in this seedling, after the tuber sprouts, a potato and sweet potato are cut into two to three parts, and then dipped in some plant ash, and placed in the drying for a quarter of an hour before they can be put into the seedling box. ”

"When we cut the pieces for the first time, we had no experience, and as a result, more than 100 were cut, more than 200 seedlings came out, and more than 100 died."

"Luckily, I found the right way."

"Mr. Motosuke taught me that there is no certainty in doing things, only half of everything is done, and when you encounter difficulties, you will retreat, you will lose the courage to face difficulties, and become timid, this is unfortunate, once a person is timid, everything will be accomplished."

Yang Bo has been silent, and after His Majesty showed some of his achievements with a little pride, he said quite sincerely: "Knowledge is the beginning of action, and action is the completion of knowledge!" Knowing the truth is practice; The practice of enlightenment and discernment. That is, to know. Your Majesty's knowledge and action are united, the minister is Da Minghe, and the minister is your Majesty! ”

Zhu Yijun was stunned for a moment, and asked seriously, "What do you mean?" ”

Everyone looked at Zhang Juzheng next to him, saying that the banquet was Zhang Juzheng's monopoly, and at this time His Majesty asked, asking Yang Bo, the leader of the Jin Party, but looking at Zhang Juzheng's posture, it seemed that he did not intend to stop it.

Zhang Juzheng's expression was extremely calm.
