Zhu Yijun brought his ministers to his nursery. At this moment, he stood in the light and made the Ming Dynasty great again, starting from the nursery.
Zhu Yijun led the ministers to a container filled with water. This was a device with a somewhat weird shape.
It is only half a foot in size. The bottom is a glass bubble the size of an egg. The glass bubble is in the water. On top of the glass bubble is a finger-thick glass tube. Above the glass tube is a wooden stopper. There is also a slender rod inserted into the wooden stopper. The glass tube is about three or four needles thick.
The entire device is filled with water, and the slender glass tube above the cork is marked with a scale.
"This is a thermometer, specially designed to measure temperature. I asked people to record the temperature of the glass bubble immersed in the ice-water mixture, and measured the height of the water surface in the slender glass tube, and recorded it as 0; immersed the glass bubble in boiling water, and measured the temperature inside the slender glass tube. The height of the water surface is recorded as 100. Then it is divided into one hundred equal parts." Zhu Yijun introduced his first small invention to measure temperature.
This device is extremely crude, but it is already the best thermometer Zhu Yijun could make in the first year of Wanli. He cannot record sub-zero temperatures, because sub-zero water will freeze and freeze the test tubes. This device is enough for the time being. If it is used in the future With a high concentration of alcohol, you can replace the water in the glass with alcohol and try to measure the subzero temperature.
It's not that Zhu Yijun didn't expect mercury, that is, mercury, which the royal family is not in short supply, but Zhu Yijun didn't have a good way to solve the problem of mercury volatilization. Mercury vapor is not only poisonous to people, but may also cause harm to seedlings.
Regarding the research and development of thermometers, Zhu Yijun will not stop, but will move forward step by step.
This less accurate thermometer records in detail the temperature at which potatoes and sweet potatoes turn green and germinate. This provides a reference for the cultivation of potatoes and sweet potatoes in the north. It can also be followed in a rational manner when promoting the cultivation of potatoes and sweet potatoes in the future. .
The fire room is a seedling room, and there is also a thermometer outside the fire room. When the Qingming Festival is approaching, potatoes begin to germinate. Outside the fire room is the control group. Under the two-phase correspondence, Daming obtained the germination temperature of potatoes and sweet potatoes, which is five to eight degrees. After germination, they will thrive only when the temperature further rises to about 15 degrees.
Zhu Yijun talked eloquently to the ministers and introduced the harvest of the glass fire chamber nursery.
Ge Shouli's jaw almost dropped in surprise. He stared at it blankly for a long time and said dullly: "Your Majesty's wonderful idea is really ingenious."
Thermal expansion and cold contraction are actually not unusual. As early as the pre-Qin Dynasty, Li Bing and his son used thermal expansion and cold contraction to crack mountains and crack rocks when treating floods. However, taking this thermal expansion and cold contraction to such an extreme is completely bizarre, and the Ming Dynasty The craftsmen realized the little emperor’s whimsical ideas.
In fact, this is degree bypass, and to be precise, it is mathematical thinking.
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 these small glass boxes contains a seedling, and these seedlings are lush and green and look alive. abundant.
"Scholar Xu." Zhu Yijun shouted, indicating to Xu Zhenming to introduce the functions of these small boxes.
Xu Zhenming didn't expect that His Majesty the Emperor would bring the Ming Dynasty court officials 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 in front of everyone. Remember, I want to pay tribute to the emperor.
"This is raising seedlings, pinch the tip, lift the tip..." After a while of fussing, Xu Zhenming got stuck. He was unprepared, so he didn't know how to make a summary.
Zhu Yijun looked at Xu Zhenming's honest and arrogant face, but he couldn't help but feel angry. He was usually eloquent, so it was useless to ask him to show off and give him a chance.
Zhu Yijun interrupted Xu Zhenming's words and motioned Xu Zhenming to step aside. It was better for him to answer the question. He smiled and said: "This is a seedling box. Water chestnuts, potatoes, sweet potatoes and other crops grown using tubers accumulate toxins from generation to generation, leading to The yield is getting lower from generation to generation, how to detoxify it?”
"The old farmer who grows water chestnuts told me that you can pinch off the tips. If you pinch off the tips to raise seedlings and plant them, the yield will be much higher. For the seedlings on the left, each one is pinched off and then sent to the fire house over there. Take it out after fifteen days of growth."
"The soil in this seedling box is all steam-fumigated soil to prevent the pinched tips from being poisoned."
Zhu Yijun did not enter the fire room. The temperature inside was around thirty-eight to forty degrees. This was high-temperature passivation. This was Xu Zhenming’s idea. It was actually the finishing process in the green tea making process. During the preparation process of green tea, in order to make the green tea After the fermentation is stopped, it will be cured through various methods such as cooking, blanching and drying.
Xu Zhenming thinks it is all poison. Can the poison be reduced by killing it?
However, if the temperature is high, the seedlings will die, and if the temperature is low, it will be of little use. Finally, after repeated experiments and determination, the specific range was determined.
Xu Zhenming succeeded. The new seedlings grown from the seedling box had plumper leaves than the old seedlings outside that had not been cured, and there were no symptoms such as yellowing or ulceration. This made Xu Zhenming particularly excited.
Zhu Yijun took a box of seedlings in the seedling box, and then picked up another box. This box had not been cured, that is, it had not been passivated by high temperature. He lifted it up and placed it on the table. The little emperor smiled. Said: "The difference is huge."
The courtiers pointed and talked around the two seedling boxes. The little emperor was engaged in farming mulberry trees, and he actually produced such results. Judging from this attitude, he really planned to plant them, rather than just showing off.
The court officials thought that the Ming Emperor's Baoqi Hall was just a symbol of the emperor's emphasis on agriculture. Even if there was not much harvested during the harvest, wouldn't the eunuchs in charge of rituals buy it? Plant the potatoes and sweet potatoes you bought into the ground, and when they are harvested, do you shout out auspiciousness?
In the Baoqi Hall of Emperor Renzong of the Song Dynasty, the Qi is two, which means two ears of wheat are grown on one wheat, which is regarded as auspicious.
During the reign of Emperor Renzong of the Song Dynasty, in order to please the emperor, the eunuchs collected double-headed wheat ears from the people and secretly planted them in the fields in front of Song Renzong's Baoqi Palace at night. When harvested, all the fields were filled with one wheat and two ears. Everyone came to congratulate and praise, God bless the Song Dynasty.
The court officials of the Ming Dynasty were gradually involved in the position of Duke Ming. Everyone was a fox for thousands of years. Of course, they could see through this trick.
Therefore, in the eyes of most courtiers, the marriage to Nongsang was just a replica of Song Renzong [Qimai Xiangrui].
It’s just to fool the emperor. If the ministers fool the emperor, won’t the eunuchs fool them too?
What the courtiers didn't expect was that the Emperor of Ming Dynasty actually stopped using such tricks and started practicing them! The two boxes in front of you are placed in the sun, and you can see the difference at a glance. They are the result of hard work.
Zhang Juzheng and Xu Zhenming were talking to the side. Xu Zhenming was mostly talking and Zhang Ju was listening.
Xu Zhenming mainly talked about what the little emperor did. Ninety-nine percent of the hard work was done. Before the little emperor came to Baoqi Hall, Xu Zhenming arranged for people to finish it. There was only a little bit of work. After the little emperor practiced martial arts, , will be specially reserved for the little emperor.
Not dangerous, not dirty, not tiring, and very engaging.
"Will Your Majesty come here every day?" Zhang Juzheng asked a very strange question.
Xu Zhenming didn't know why Yuan Fu asked like this. He said quite accurately: "It rained the day before yesterday, and His Majesty also came. His Majesty comes every day."
Zhang Juzheng held up his hands, clenched his fists, and looked at the back of the little emperor. The little emperor was not fooling around, and he had no intention of giving up halfway. He was ambitious, had the world in his heart, and persevered. He was a wise king, a virtuous master, and a warrior.
For the first time, Zhang Juzheng had the feeling that the revival of the Ming Dynasty was not a mirror image. This feeling was extremely certain and real.
"You did a good job. This is the badge of the Quanchu Guild Hall. Take it and don't lose it, and don't lend it to others. If you have something to do in the future, come to the Quanchu Guild Hall to look for me." Zhang Juzheng took a piece from his waist without leaving any trace. The waist badge was handed to Xu Zhenming.
"Thank you Yuanfu for your appreciation!" Xu Zhenming was extremely surprised and bowed to Zhang Juzheng. It is not just about money, but also about ability. Having ability is not enough, but also about connections.
To this day, Xu Zhenming doesn't know why she was recommended by Zhang Juzheng to serve as a bachelor at the emperor's side, and now she has become a disciple of Zhang Juzheng.
Zhang Juzheng said gently: "Bing Jing, Tan Jing, there is no need to think of a way, you don't have the means, just work well by His Majesty's side and cultivate the land well, and absolutely cannot let anyone ruin His Majesty's farming affairs. No matter it is a eunuch, a Tiqi, an honorary guard, a saber-wielding warrior or an old farmer, it is absolutely not allowed."
Zhang Juzheng knew that some people did not want to see the emperor reap great results from his farming. If he tried to play the trick of "Qimai Xiangrui", no one would stop him. However, if the emperor put his practice into practice and really wanted to reap the rewards, some people would not be happy and would Get in the way.
Because if there are really results, it will solidify the foundation of imperial power.
In fact, Xu Zhenming was not good at cheating, let alone taking bribes and bending the law. He paid two thousand taels of silver for filial piety twice a year. Xu Zhenming was a Jinshi who carried a bamboo book box, where could he find two thousand taels of silver a year to pay filial piety?
Zhang Juzheng exempted him from filial piety, as long as he did what he was best at, farming, and took good care of these ten acres of land.
Planting potatoes and sweet potatoes well can really yield more than a thousand catties per acre, and it can also increase the vitality of the weak state affairs of the Ming Dynasty.
Zhu Yijun glanced at Zhang Juzheng and Xu Zhenming, but did not say anything to stop them, let alone interrupt them. If Xu Zhenming wanted to do something, he had to get someone's name. Zhang Juzheng was willing to accept it, which was Xu Zhenming's opportunity.
When you come out to hang out, you need to focus on strength, and more importantly, power. For at least ten years, Zhang Juzheng will be the biggest backer of the Ming Dynasty.
Zhu Yijun pointed to the roots in the seedling box and said: "There are many things to pay attention to in this seedling raising. After the tubers germinate, cut a potato or sweet potato into two or three parts, then dip it in some plant ash and let it dry for a quarter of an hour before putting it into the seedling box. "You can't skip this step. If you skip the plant ash, the seedlings will easily get sick."
"The first time we cut into pieces, we had no experience. As a result, we cut more than 100 seedlings, more than 200 seedlings came out, and more than 100 died."
“Thankfully I found the right solution.”
"Mr. Yuan Fu taught me that there is no certainty in doing things, only do half of everything, and shrink back when encountering difficulties. You will lose the courage to face difficulties and become timid. This is not perseverance. Once a person is timid, nothing will be accomplished. "
Yang Bo remained silent. After His Majesty showed some of his achievements with a little complacency, he said sincerely: "Knowledge is the beginning of action, and action is the completion of knowledge! The true and true nature of knowledge is action; action is clear. Awareness and careful observation. That is knowledge. Your Majesty’s knowledge and action are unified. I congratulate you for the great Ming Dynasty. I congratulate your Majesty!"
Zhu Yijun was stunned and asked seriously: "What do you mean?"
Everyone looked at Zhang Juzheng next to them. The banquet was Zhang Juzheng's exclusive business. At this time, His Majesty asked Yang Bo, the leader of the Jin Party, but looking at Zhang Juzheng's posture, it seemed that he did not intend to stop him.
Zhang Juzheng's expression was extremely peaceful.
