"Draft of Chinese Agricultural Bet365 app download science and technology" edited by Liang Jiamian，Is by far the most comprehensive、The most systematic history of Chinese agricultural science and technology，After publishing, it is unanimously praised by academic circles at home and abroad。The writing of this book was proposed at the conference of the Publicity Department of the Central Committee of the Communist Party of China in Dalian in 1965。December 1978，The Ministry of Agriculture and Forestry is in the form of (78) Agricultural Forestry (Science and Education) No. 68，Deployment Writing Work。March 1979，The Ministry of Agriculture and Forestry entrusted the Chinese Academy of Agricultural Sciences to hold the first meeting in Zhengzhou，Entry and review committee with Lin Shan as the director and the writing committee edited by Liang Jiamian，Writing teams for more than 40 agricultural history experts。About the situation of this meeting，No scholar composition description has been seen at present。The author's related materials deposited in Yang Kuan's manuscript，Just Yang Kuan、Hu Dao Jingyou will be explained slightly，To enrich our cognition of this meeting，It can also enrich our understanding of the details of the writing process of "History of Chinese Agricultural Science and Technology"。

This meeting invited many scholars to go，In advance to distribute the proposed outline to distribute related scholars。Yang Kuan is being invited to be among the invitation，Maybe due to busy work，He failed to attend the meeting，Please friends Hu Daojing bring his four opinions to the participating scholars，For reference。He put forward four opinions on the outline，The first is the division of the history of Bet365 app download science and technology，Second, how to properly explain the development of agricultural science and technology and the relationship between the development of productive forces at that time and the relationship between agricultural policy，Third, the relationship between the development of agricultural science and technology and the relationship between the social and economic development of various regions and how to highlight the key points，Fourth, the learning style of advocating truth -seeking。The draft of the opinion is as follows:

From the content of the entire outline，It is considered comprehensive and thoughtful。I just use the requirements of historical workers，Put forward a few days of early views，Provide reference。

(1) How to divide the history of agricultural Bet365 app download science and technology to divide the stage of stage

I hope the writing of this book，Not only take care of the stage of my country's social development，It is also necessary to divide the stage according to the characteristics of the development of agricultural Bet365 app download science and technology。Both the general law of social development，It is necessary to express the special laws of agricultural science and technology development，allow readers to see the main characteristics of the development of agricultural science and technology in each period，You can also see the major role of the development of agricultural technology at that time for the development of social history。

At present, the third edge of this outline uses the Spring and Autumn and Warring States Period as a stage，It can be discussed。In the staging of ancient history of our country，There are different opinions in the academic world，But Spring and Autumn、As a major change period of the Warring States Period，Opinions are still the same，or from slavery to feudal system，or the transition from lord system to landlord system。and the development of agricultural productivity，Including the development of agricultural production technology at that time，It is an important factor that promotes this transformation。Now dividing the Spring and Autumn and the Warring States Period into a stage，It is difficult to see the relationship between it and this change。Title of this part: "Agriculture and precision technology in the Spring and Autumn and Warring States Periods"，In fact, in the middle of the spring and autumn, Bet365 lotto review it is not possible to talk about fine cultivation.。At the beginning of this part, "Widely Use of Iron Agricultural Set"，In fact, it did not do this in the Spring and Autumn Period。and the lack of information in this area in the Spring and Autumn Period，Write together in the Warring States Period，Very difficult，Not coordinating。

The fourth editor takes the Qin and Han dynasties as the first stage，The fifth editor is based on the Sui, Tang, Song Yuan as the first stage，Both stages have eight hundred years，It seems too long。This is a long stage of division，It is difficult to write the characteristics of each era，Can the time divide the time be appropriately reduced。

(2) How to properly explain the development of agricultural Bet365 app download science and technology and the relationship between the development of productivity at that time and the relationship between agricultural policy

In the past, the development of agricultural policy and agricultural production technology in each period was not enough，This outline noticed this，Is very good。I think it will be appropriately explained and explained in this regard，It is necessary。For example, some dynasties have implemented a restoration policy implemented by the landlord regime in the early days of the landlord，What role does it play on the development of agricultural production and agricultural science，It needs appropriate explanation。The role of agricultural Bet365 app download science and technology on the development of various times and even the entire socio -economic development of agricultural science and technology，Research is not enough。Often simply talk about technology，Dare to emphasize its role。Of course, it must be very difficult to say its role，But you can also use some specific information to explain。For example, the growth of household registration and hukou controlled by the state during a certain period，It also reflects the results of the development of agricultural production in a relatively stable situation at that time，This should also have something to do with the development of agricultural production technology at that time。

(3) The relationship between the development of agricultural Bet365 app download science and technology and the social and economic development of various regions and how to highlight the key issues

The development of agricultural economy in various regions in our country is unbalanced。bet365 Play online games Different regions due to different natural conditions and historical conditions，The development of agricultural production and agricultural Bet365 app download science and technology also has different characteristics。Sometimes this area is more advanced，Sometimes that area is more advanced，Sometimes a certain agricultural crop in a certain area has special development。How to prominently describe advanced technologies in certain regions in a certain period，Describes the outstanding achievements of cultivation of a certain crop，Highlights，I think it is necessary。For example, after the Song and Yuan Dynasties, the production technology of rice and cotton in Jiangnan area，It should be used as one of the priorities of this period。At the same time，The decline of agricultural economy in some areas and the rise in agricultural economy in some areas，Impact on the development of agricultural science，It should also be appropriate。For example, the Yangtze River Basin, especially Jiangnan,，How to gradually rise such as agricultural production，Why did the south produce more than the north after the Sui and Tang dynasties，How can agricultural production technology develop greatly，Should be explained appropriately。I think you can consider highlighting some key points in this book，In particular, the development of more important and important crop production technology。If you only take care of full，while ignoring outstanding points，It is not easy to make readers deeply understand，It is not easy to make this work significantly affect。

(4) Promote the problem of learning the style of seeking truth from facts

As a history of a certain technology，It needs to summarize the predecessor's research results and highly summarize。It is necessary to quote the necessary ancient literature，It is also necessary，Then absorb it and melt。About this cannot be explained in the text，Whether it can be appropriately instructions。This respects the results of the work of predecessors，It is also convenient for readers to further study。The results of foreign bet365 best casino games scholars should also be the case。In the past, there were some popular works or the paper written，Wipe the research results of predecessors，East Copy West Rejuvenation，The source of the source is not injected，This bad style must be corrected。

above four opinions，It's just the one person thought for a while，Not necessarily desirable，Please correct。

Meeting to discuss on March 5th，End on the afternoon of March 9。That night，Hu Daojing returns to Shanghai。Due to busy things and tired journey，Hu Daojing failed to go to the door to explain the meeting to Yang Kuan，So，Write on March 11 to inform Yang Kuan's meeting。Letter as follows:

1979.3.11 midnight

In short，Although Yang Kuan cannot attend the meeting，But from the scholar's responsibility，I made four reference opinions，and please bring Hu Daojing to the conference。Hu Daojing connected two letters to inform Yang Kuan meeting，It can be seen that its solemnity to Yang Kuan。This can also be seen，Behind a collective book publishing，In addition to actual participants，There must be a lot of Yang Kuan、Hu Daojing's obscure scholar，Their care and opinions of their concern for "History of Chinese Agricultural Bet365 app download science and technology" are worthy of our memory。
