To be a student, you must know the rules! Follow the rules and regulations of the school.

It must not be too low-key! Too high-profile is easy to cause trouble, too low-key is easy to get into trouble!

The reason why a person sometimes appears to be high-profile is not deliberately expressed, but unintentionally!

For example, the way he dresses, the way he acts, and the temperament he is born with!

The campus is so big and so many students that it's no different from a small city.

When Mei Xiaohan entered school two days later, he encountered something that made him very unhappy, that is, the campus bully found him!

To put it in layman's terms, it is to collect protection money.

"If you don't study well at a young age, you will learn from the big brother of the society to collect protection money!" Mei Xiaohan wanted to refuse him, but for unnecessary trouble, she still gave him the money.

The classmate who collects protection money is said to earn more than 10,000 yuan a month by collecting protection fees, which is a very good business experience.

"There is a price to pay for everything, this is an eternal truth!"

When the instructor walked into the classroom with Mei Xiaohan and Yun Xiaoyao, both of them were stunned. Because, twenty-four of the thirty-two people in the class were girls, and only eight were boys, and the two boys were still two of them.

At this moment, the happiest thing is that Yun is free, Mei Xiaohan has always felt that he has a bad mind and is a romantic ruffian.

The ancients thought it was impossible for men and women to study together, so that there were things like men and women not kissing!

From the moment he walked into the classroom, Yun Xiaoyao's eyes never took his eyes off those girls.

"The fact that students are coming to our school one after another shows that the popularity of our school is constantly improving. This is something that the university is very proud of. ”

Although Mei Xiaohan had secretly scolded the instructor hundreds of times in his heart, he still maintained a smile on his face, he couldn't stand this kind of boasting the most, and it was excessive boasting.

Yun Xiaoyao was simply crazy with joy, but he didn't show it. He was happy because he saw many beautiful girls.

...

Putting Yun Xiaoyao in the class is tantamount to driving the wolf into the flock. Maybe this statement is a bit exaggerated, but it can reflect Yun Yao's character very well.

"You should know what we're here for, it's a warning to you!"

"Mei Gongzi... Please pay attention to your identity and don't talk nonsense! Yun Xiaoyao said: "Don't slander people without evidence!" ”

"It's better to do that! Don't make a big news for me! ”

The new class members caused some small fluctuations, because there were so few boys in the class that things were scarce and expensive, and it was true!

Going back to school again, there was a different feeling that was hard to put into words.

Changing from a junior high school student to a college student will naturally have a lot of discomfort. This maladaptation is not in life, but in concept.

has been wandering on the rivers and lakes for many years, Mei Xiaohan is naturally no longer the hairy boy he was back then, although it seems that his classmates are older than him, but Mei Xiaohan is far more mature than them.

Agronomy is a scientific discipline that studies the natural and economic laws of agricultural development, and is comprehensive because it involves a variety of sciences such as agricultural environment, crop and livestock production, agricultural engineering and agricultural economy, among which forestry science and aquatic science are sometimes included in the broad scope of agricultural science.

Graduates are expected to acquire knowledge and competencies in the following areas:

1. Solid knowledge of mathematics, physics, chemistry and other basic theories;

2. Master the basic theories and basic knowledge of biology and agriculture;

3. Possess the skills and methods of agricultural production, especially crop production;

4. Have the awareness and basic knowledge of sustainable agricultural development, and understand the scientific frontiers and development trends of agricultural production and science and technology;

5. Familiar with the relevant guidelines, policies and regulations of agricultural production and rural work;

6. Master the basic methods of scientific and technological literature retrieval and data inquiry, and have certain scientific research and practical work ability.

The major of agronomy cultivates senior scientific and technical talents who have the basic theories, basic knowledge and basic skills in crop production, crop genetics and breeding, seed production and management, etc., and can be engaged in agronomy-related technology and design, promotion and development, operation and management, teaching and scientific research in agriculture and other related departments or units.

In fact, the formation of modern agricultural science has only a history of more than 100 years, but the process of its occurrence and development has a long history.

The formation of knowledge such as ancient astronomy, phenology, calendars, and surveying is actually related to the early agricultural production practices of human beings.

At that time, people had already begun to explore agricultural production conditions, seasonal changes, and land use methods.

Subsequently, the progress of people from trying to understand the agricultural environment to trying to change the environmental conditions and the objects of agricultural production itself has promoted the gradual systematization of knowledge in soil cultivation, fertilization, irrigation, as well as the breeding and cultivation of crop varieties, and the rearing and breeding of domestic animals.

The vast Chinese agricultural books have provided strong evidence for the glorious achievements of ancient agricultural research.

It was not until the middle of the nineteenth century that the research results of biology, chemistry, physiology, genetics, entomology, microbiology, soil science and meteorology, as well as their experimental methods, were gradually applied to agriculture, which promoted the qualitative change of agricultural research from the empirical level to modern agricultural science.

The publication of Liebig's classic work "Applications of Organic Chemistry in Agriculture and Physiology" in 1840 is generally considered to mark the beginning of the development of modern agricultural science system.

Since then, various agricultural sciences have been formed on the basis of experiments.

The application of agricultural chemistry in crop cultivation has led to the establishment of chemical fertilizer industry and the development of plant physiology and plant nutrition, and crop cultivation technology has become more scientific.

Mendelian laws of heredity and genetics led to the birth of modern crop breeding. As the principles of biochemistry, physiology, pathology, anatomy and genetics were applied to livestock production, livestock breeding, breeding and feed science, as well as veterinary medicine, developed rapidly.

At the beginning of the 20th century, power machinery, especially internal combustion engines, tractors and other motorized agricultural tools, was gradually promoted, and the situation of using animal power as the driving force for agriculture changed, accelerating the process of agricultural mechanization. The resulting science of agricultural machinery provides a theoretical basis for continuously improving agricultural productivity.

After the Second World War, the rise of the synthetic chemical industry promoted the research of various pesticides, herbicides and agricultural plastics, and the means of plant protection were improved day by day.

With the development of cytogenetics and molecular genetics, the application of genetic engineering and other biotechnology in agriculture has begun to bear fruit, indicating a new revolution in breeding technology.

The application of ecological science and systems science in agriculture has opened up new ways and fields for the development of agricultural science from a macro perspective.

At the same time, new research methods provided by nuclear technology, electronic computers, remote sensing, telemetry, etc., have made and are making agricultural scientific research more sophisticated.

As a result of the progress of agricultural science and technology, agricultural producers have not only been able to increase agricultural labor productivity several times or even dozens of times, but can also greatly increase the unit output of various animal and plant products, effectively improve the quality of products, and greatly reduce the losses caused by harmful organisms and unfavorable natural conditions.

Agricultural science has become an indispensable component of agricultural productivity and a necessary condition for agricultural modernization and a high-speed increase in the level of agricultural production.

In just one year, it is obviously impossible to learn too much knowledge, but this time Mei Xiaohan has a new goal!

That is to use modern agriculture to change the Great Song Dynasty!
