Opening the history of modern science and technology development in China，Zhu Kezhen、Bingzhi、The names of many older generation scientists such as Hou Debang，Suddenly caught our eyes。Zhu Kezhen is an outstanding representative among the older generation of scientists，Carrying out mobile bet365 research for decades。He pioneered research in the fields of phenology and the history of climate change in China，Working hard to promote the development of China’s mobile bet365 undertakings，Written a glorious scientific life。At the same time，This also shows that he cares about the country’s agricultural development、Feelings of family and country to revitalize mobile bet365 undertakings。

　　Adhere to the original intention of “saving mobile bet365 through science”

mobile bet365’s situation in the times，It is the realistic premise for the formation of his family and country feelings。As Marx said，“These are some realistic individuals，It is their activities and their material living conditions，Including the material living conditions they obtain ready-made and created by their own activities”。Therefore，“Any historical record should start from these natural foundations and their changes due to people’s activities in the course of history”。

In terms of mobile bet365’s era，His youth was at the end of the Qing Dynasty，China has gradually become a semi-colonial and semi-feudal society，Invasion by foreign powers、Warlords melee，Making people miserable、Life is in ruins。Witnessed it all，He thinks，Although China has thousands of years of civilization，Have excellent cultural traditions，But still bullied by foreign powers，Mainly because science and technology are inferior to humans。He realized，To make the country rich and strong，No longer be humiliated by foreign powers，Changing the country’s backwardness，Must study hard，Saving the country through science。When he was studying in Shanghai，Study very hard，Often forgetting to eat and sleep。Later，He was admitted to Tangshan Road and Mine School，Through hard study，In five exams in one and a half years，First in the class every time，Is the best student in the school，Even those arrogant British teachers looked at him with admiration。

1910，mobile bet365 passed the second Geng Scholarship Examination to study in the United States，Going to study in the United States with 70 candidates in the same period。When choosing your major，He thought，China built its country on agriculture，Everything is based on agriculture，So，He chose to study at the College of Agriculture at the University of Illinois in the middle of the United States。Through study and practical inspection in school，mobile bet365 saw it，American agriculture is highly productized、Automated，China’s agriculture is still at the stage of self-sufficient small-scale peasant economy，There is a huge difference between the two。Things he learned in college，Far away from the reality of Chinese agriculture。Summer 1913，After graduating from mobile bet365 University，When choosing a specialization for further study，I chose meteorology, which is closely related to agriculture，Admitted to the Department of Earth Science of Harvard University to study meteorology。

In American Meteorologist Ward、Under the guidance of McCandy，mobile bet365 received his master’s degree in 1915。After，He applied to extend his study time for another three years，Continue to study for a PhD。During this period，Although China is already in the Republic of China period after the Revolution of 1911，But it’s still a melee between warlords、People are in dire straits。This further strengthened mobile bet365’s belief in saving the country through science。He thinks，The domestic political chaos at that time，The future is slim，Only advanced science and technology，Only can China develop towards a modern society。He actively participated in the work of the "Chinese Science Society" initiated by Chinese students studying in the United States，Editor of "Science Monthly"，Use all your spare time to check information in the library，And set his research goal as climate research in China。For this，In addition to studying meteorology、Climate、Geology、In addition to more than ten courses including geography，Also took History of Natural Sciences。1918，mobile bet365’s thesis "New Classification of Typhoons in the Far East" passed the defense，After receiving a PhD from Harvard University，He resolutely decided to return to serve in China。

　　mobile bet365 talent training

As a student returning from studying abroad，mobile bet365 is full of patriotic enthusiasm，Decided to choose to teach in a university，Want to cultivate more talents for the country，To change China’s backwardness。1919，After mobile bet365 returned from studying abroad for 8 years，On the university podium，Invited by Wuchang Higher Normal School (the predecessor of today’s Wuhan University)，Go to the school to teach geography and meteorology。1920，He was hired to teach at Nanjing Normal University。

　1921，Nanjing Higher Normal School Expansion，Renamed Southeast University。At Zhu Kezhen’s initiative，Southeast University established the Department of Earth Sciences。This is the first earth science department established in a Chinese university，Zhu Kezhen serves as department chair。Department of Earth Sciences consists of Geography、Weather、Geology、Four majors in minerals，The meteorology major is also the first meteorology major in a Chinese university。From now on，China has begun its own history of cultivating mobile bet365 professionals。There were no teaching materials at that time，He wrote the textbook "Meteorology" by himself。To guide students to understand the composition of air at different heights，Understanding temperature、Air pressure，Cloud, fog, frost and snow，Thunderstorm、Hail，Wind、Climate phenomena such as storms and typhoons，He imparts complex mobile bet365 knowledge to students in the classroom in a "moisturizing and silent" manner。Except classroom teaching，Zhu Kezhen attaches great importance to the cultivation of students' practical ability，And make field practice a required course for all subjects in the Department of Earth Science。In addition，He also set up a weather station on campus，To train、Cultivate students’ practical work ability。In his 10 years of coaching，Trained a large number of mobile bet365 professionals for the country。

　　Creating a mobile bet365 career

As a meteorology expert，To change the backwardness of China’s mobile bet365 undertakings，Creating a new situation in China’s mobile bet365 undertakings，Zhu Kezhen carefully drafted the "Plan for Establishing a National mobile bet365 Weather Monitoring Institute" and put it into practice。1928，Zhu Kezhen was appointed director of the Central mobile bet365 Institute。Because China did not have a unified management agency for mobile bet365 work at that time，Therefore, the Central mobile bet365 Institute shoulders a dual mission: it is also a national mobile bet365 academic research institution，At the same time, it is the leading organization for the national mobile bet365 undertaking。Under his leadership，In addition to the original ground mobile bet365 observations，The Central mobile bet365 Institute has successively carried out high-altitude weather observations、Weather forecast and weather broadcast。At the same time，The institute also carried out phenology、Sunshot、Air Electric、Observation business and research work on fine dust and earthquakes。Continue，In Nanjing、Beiping launched a wind measuring balloon、Sounding balloon、Aircraft detection and mobile bet365 kite work。

Before the establishment of the Central mobile bet365 Institute，China’s weather forecasts are mainly issued by mobile bet365 observatories run by foreigners in China。New Year’s Day 1930，The management rights of coastal weather stations have been taken back，The Central mobile bet365 Institute officially draws the weather map of East Asia，Issue weather forecast and typhoon warning。From now on，China has weather forecasts for its own territorial waters。Same year，Zhu Kezhen led the team to participate in the Far East mobile bet365 Conference held in Hong Kong。During the meeting，The Governor of Hong Kong and the President of the Conference held two banquets。At the banquet，The seats of China and another country are arranged at the bottom。Zhu Kezhen thinks，This is an arrangement that is detrimental to China’s national character，It is intolerable。He decided after discussing with the Chinese members attending the meeting，Protest by not attending the meeting，And take the sea ship back to Shanghai in advance。After experiencing these things，Zhu Kezhen further strengthened his determination to independently establish China’s mobile bet365 industry。

Zhu Kezhen devoted a lot of energy and effort into the construction and development of Beijige mobile bet365 Research Institute。1932，Beijige mobile bet365 Office started recording earthquakes，It is one of the earliest seismic stations in China。Zhu Kezhen also has a grand vision for developing national mobile bet365 undertakings。He elaborated on meteorology and agriculture in the "Plan for Establishing a National mobile bet365 Climatology Institute"、Fisheries、Navigation、Aviation、Water Conservancy、Scientific Development、Break the superstitious relationship，Proposed to set up mobile bet365 observatories in various regions across the country，View area size、Terrain、Population Weather Monitoring Station。According to his plan，Within 10 years，There should be 10 weather stations across the country、180 weather stations、1000 rainfall stations，For China’s agriculture、Water Conservancy、Navigation、Aviation、National defense and other services。However，Under the circumstances，This goal is difficult to achieve in a short time，But he has been working tirelessly to achieve this goal。He dispatched professionals to carry out alpine weather measurement on Mount Emei at an altitude of more than 3,000 meters；Raising funds from multiple parties，A mobile bet365 observatory was established at Riguan Peak of Mount Tai；Relevant professionals were dispatched to establish a climate measurement station in Lhasa, Tibet，Started mobile bet365 observations on the roof of the world。To solve the serious shortage of mobile bet365 professionals，Under his auspices，The Central mobile bet365 Institute has launched four mobile bet365 study classes，Trained nearly a hundred trainees and assigned them to mobile bet365 departments at all levels。

　　mobile bet365 on climatology and agricultural production

After the founding of New China，Zhu Kezhen serves as the vice president of the Chinese Academy of Sciences，Working hard to develop the country’s mobile bet365 undertakings，Always care about meteorology and serve industrial and agricultural production。For this，He is interested in phenology、Pioneering research on agricultural climatology and climate change in China over the past dynasties，Made outstanding contributions。For example，Zhu Kezhen discussed the relationship between climatology and agricultural production in his article "On Several Characteristics of my country's Climate and Its Relationship with Food Crop Production"。He pointed out，Plants are more restricted by climate than humans。In terms of plants，In cold and tropical zones、Mountains and plains、Deserts and Wetlands，The types of vegetation that grow are completely different。The thickness of a tree’s leaves and the distribution of chlorophyll、Depends on the comprehensive sunlight intensity。The effects of red light and blue light are different。Red light makes cells grow，Blue light causes cells to divide。The reason why plant chlorophyll can produce various carbohydrates，Its energy relies on solar radiation，The total annual radiation in a place can be used to preliminarily estimate the crop yield per hectare or per acre under assumed ideal conditions。In addition to sunshine，Temperature is also an important factor affecting crop production。For example，Litchi、Longan is only produced in southeastern China，Tea、Oranges are no better than Qinling Mountains，Most tropical plants cannot withstand frost。Growth speed of crops，Whether it is measured by the length and thickness of branches, leaves and roots，Still based on the weight of the crop，The fastest is when the temperature is 30℃。When the temperature drops below 30℃，The lower the temperature，The slower it grows，Until about 5℃，Most crops enter dormant state。If the temperature rises above 30℃，The growth rate must also decrease，The temperature reaches 40℃，Most crops also stopped growing。Rainfall is also very important for the growth of crops。Most of the world’s rice production is concentrated in the East and Southeast Asian monsoon regions。History，East and Southeast Asia’s rice production accounts for 96% of the world’s total production，The high temperature and abundant rainfall in summer in monsoon areas are an important factor。In China，Impact on crop harvest，Rainfall is more important than temperature，Mostly it depends on the timing of rainfall。Most areas in China belong to the monsoon climate zone，One characteristic is that rainfall is concentrated in the summer when the temperature is high；Another characteristic is，The onset and retreat of the summer monsoon sooner or later，What causes less or more rainfall。High rainfall can easily cause floods，Lack of rainfall and easy to cause drought。

Zhu Kezhen pointed out at the end of the paper，Since climate is an important factor in the current increase or decrease in food production，We need to analyze how climate affects food production，And further explore how to take advantage of the favorable factors of a local climate，Reduce or eliminate the adverse factors of a local climate。Reading between the lines of this paper，Every data、Every conclusion，Not only allows us to see the rigor of Zhu Kezhen’s interpretation and analysis、Scientific，You can even see his concern for the country’s agricultural production as a mobile bet365 expert。This paper by Zhu Kezhen，Decades of accumulated research results，Three changes to the draft，This shows how deeply he devotes himself to climate research，Care for the country and agricultural development。This is not only a rigorous and professional scientific paper，And he is concerned about the country’s agricultural development、A true portrayal of the feelings of family and country in revitalizing the mobile bet365 industry，It is also an important document for promoting China’s agricultural production。

The scientific life and feelings of the older generation of scientists such as mobile bet365，Not only promotes Chinese science and technology、Education、Culture、The development of industrial and agricultural production and other undertakings，And inspires generations of scientific and technological workers to love the motherland、Dedicated to science、Serving the society。
