Previous page        Return to Catalog        Next page

    Seeing that the mountain chief finally relented, the students in the School of Business all breathed a sigh of relief. They all secretly rejoiced, feeling that the hard days were finally over.

    Although the truth is cruel, the facts are there There are still only a few people who can, like Shi Jizhi, experience many benefits from farm work, such as strengthening the body, tempering the will, making the article more real, insightful, condensed and down-to-earth.

    Most scholars only think that farming is a kind of torture.

    This is understandable. How many scholars are willing to stick their buttocks out and work in the fields all day long?  Isn't it all because Ma Yilong is highly knowledgeable and has been in education for half his life? Isn't it true that he is an out-and-out authority in the imperial examination?

    Their calculation is that even if they only spend half the time studying in Wushu Academy, it is better than letting those second-hand teachers guide their studies, and it is much better than working behind closed doors.

    Now Mr. Zhao has promised them that after going to Kunshan, the famous teachers from Yufeng Academy will be responsible for their studies to reduce the burden on the mountain chief.  But these guys were so happy.

    Because the mountain chief has to deal with 600,000 acres of land and 60,000 farmers every day, as well as agricultural scientific research, he definitely has no time to continue tossing them.

    ??And Mr. Zhao will also take time to give them guidance.  In the Ming Dynasty, Mr. Zhao is the only one who can surpass their master in teaching people to study, right?

    ??Although a certain scholar from Suzhou Prefecture may express dissatisfactionbut a five-level Jinshi is a golden sign.

    Ma Yilong couldn't help but feel secretly annoyed when he saw the expressions of the students.  Then he sneered and said: "Don't worry, I won't ignore you when we get to Kunshan. At least I will supervise you and continue to plant the land."

    "Yes, Chief Shan" The students became eggplants beaten by frost.

    ??~~

    After lunch, Ma Yilong sent his disciples to work in the fields.  Even if you want to hand over the academy land to others to take care of it, you still have to complete all the preparatory work before farming.

    He and Zhao Hao were under the pergola, talking about agricultural technology.  Ma Yilong has been farming for many years and has read agricultural books of all ages. He has rich experience and solid theory.  Traditional agriculture is a business that relies particularly on experience and practice.  He believed that no one knew more about farming than him.

    Ma Yilong has even insisted on using the ¡®ear selection method¡¯ to increase yields for many years.

    To put it simply, after the rice matures, the strongest man is selectedoh no, Suizi.  Thresh separately and reserve for seed use.

    This method is very laborious, but if you stick to it year after year, the results are really amazing.  The yield per mu of his academy is already twice the average.

    It¡¯s a pity that ordinary people are always unable to adopt this kind of sophisticated gameplay, resulting in Liyang¡¯s per-acre yield being slow to keep up

    Although Zhao Hao has never farmed before, he has a lot of new agricultural knowledge that the other party has never heard of. The impact on Ma Yilong can be imagined.

    He told Ma Yilong why ¡®the crops are all dependent on manure¡¯ because the fermented manure is rich in nitrogen, phosphorus, potassium and various organic matter.  Nitrogen, phosphorus and potassium are nutrients required by plants and taken away in large amounts during harvest.

    But the amount of them returned to the soil in the form of stubble and roots is not large, so these three nutrients must be continuously replenished to allow plants to thrive.

    "Egg-soaked armor?" Ma Yilong naturally had never heard of it.

    "You haven't studied Chemistry, and I don't understand it even if I tell you." Zhao Hao felt that it was necessary to attack Comrade Lao Ma's over-inflated self-confidence.  He took a sip of tea and said slowly:

    "You only need to know that nitrogen, phosphorus and potassium correspond to leaves, roots and stems. I will teach you another jingle. When you see the condition of the crops in the future, you will be able to judge for yourself what is missing and what is needed."

    "Well, please speak." Ma Yilong nodded, indeed he was shocked.

    "Look carefully to see what is missing, nitrogen, yellow, red, phosphorus and potassium brown spots. Potassium supports lodging and phosphorus resists drought. The branches and leaves are yellow and thin because of nitrogen. Nitrogen grows leaves and phosphorus grows fruits. With potassium fertilizer, the waist is thick." Zhao Hao smiled and said to the junior high school biology  The characters that appear in the book teach junior high school biology knowledge, which feels great.

    It¡¯s like, just like using Sister Ma¡¯s poems to move Sister Ma, it makes people almost have an intracranial orgasm.

    Thinking of this, he couldn't help but glance at Ma Xianglan sitting next to him, and Secretary Ma responded with a refreshing smile.  Although I always feel that the young master¡¯s smile is a bit malicious

    ??~~

    Zhao Hao told Ma Yilong again, but he should also be careful about going too far and not going too far.  Excessive application of nitrogen will cause plants to become green, late-maturing, prone to lodging, and susceptible to disease attacks.  Root crops can also cause disappointing root yields due to leaf growth.

    Excessive phosphorus fertilizer will cause crops to mature late and reduce seed setting rate.  Excessive potassium fertilizer can cause yield loss and heart rot.

    Ma Yilong was dumbfounded when he heard this. He had thought that Zhao Hao would never touch Yang Chun.Even if your son-in-law has some agricultural knowledge that he doesn¡¯t know, it¡¯s only a little bit.  I didn¡¯t expect it to be so systematic and practical!

    ¡°Is this the power of science?¡± He murmured and sighed, asking Shi Jizhi to quickly take a pen and ink to write it down.

    Zhao Hao immediately gave Ma Yilong a box of pencils. It was too strange for an agricultural technician to use a writing brush. It was better to use a pencil stub with cigarette pack paper, which was more in line with his professional image.

    Ma Yilong is naturally familiar with lead chisels, but Zhao Hao's box of pencils is much more practical.  I saw that a black lead core was embedded in the grooved wooden strips, and then the two wooden strips were glued together.  There is also a small knife in the box, which is obviously used to sharpen pencils.

    "Zhonghua brand?" Ma Yilong saw the trademark on the box and couldn't help but praise: "Young master is really patriotic."

    "That's right." Zhao Hao smiled awkwardly and said in his heart, it's actually because of my bad taste.

    Ma Yilong used a pencil to write down the knowledge that Zhao Hao had just imparted.  Then he raised his head and asked, "Then where are these three treasures?"

    "Currently, potassium fertilizer mainly comes from plant ash; nitrogen fertilizer mainly comes from decomposed human and animal urine In fact, soybeans, forget it, pretend I didn't mention it; phosphate fertilizer comes from fish scales, fish bones, animal bones, egg shells, clam shells, chicken, duck, goose and guano, etc.  There is abundance.¡±

    "That's it!" Ma Yilong slapped his thigh suddenly and excitedly revealed his exclusive secret recipe: "I collect shells from the river, grind them into powder and sprinkle them on the ground. The harvest will be much higher. Sure enough, nitrogen grows.  Phosphorus leaves grow fruits!¡±

    ¡°Also before the wind and floods, I will sprinkle plant ash on the ground to prevent lodging. It turns out that it is because of the presence of potassium fertilizer!¡±

    After all the confirmations, Ma Yilong was convinced of Zhao Hao's theory and held him tight, as if he wanted to squeeze him dry.

    "You just said that all nitrogen, phosphorus and potassium are present in feces?"

    "Of course, feces is golden juice."

    "That's right!" Ma Yilong couldn't help but feel like a confidant when he heard this.  "I often say that a mountain of gold and silver is not as good as a mountain of dung. It's a pity that they always think that I am sick."

    "That's because they are ignorant." Zhao Hao laughed and said: "In order to encourage people to actively compost, I spend money to collect dung. A load of human dung is 10% of water, a hundred catties of cow dung is 10%, and a hundred catties of pig and horse dung are  Fifteen points, one hundred pounds of poultry manure is twenty points, and one hundred pounds of sheep manure is also twenty points!

    Hearing his classified quotations, Ma Yilong asked with interest: "Poultry manure is rich in phosphate fertilizer and the amount is small. I understand this. Why is sheep manure so expensive?"

    ¡°Among all kinds of livestock manure, sheep manure has the highest nitrogen, phosphorus, and potassium content, followed by pig and horse manure, and cow manure has the lowest; the amount of excretion is cow manure, followed by pigs and horses, and sheep manure is the least.  Such a price." Zhao Hao smiled and replied: "It's very reasonable, right?"

    "It's reasonable, very reasonable!" Ma Yilong applauded and praised: "Now all the shit in Kunshan belongs to us!"

    "The people of Kunshan still raise too few livestock. We will have to think about Suzhou City later." Zhao Hao said, dissatisfied with his desire.

    "That's one million people in Suzhou. How many people will we need to attract" Ma Yilong was leisurely fascinated.

    The two of them were chatting enthusiastically, but the people next to them almost vomited out their lunch.
