1. climatic conditions: firstly, the varieties, farming systems and production seasons that climate restricts agricultural production in a region are introduced. Then, by analyzing "Figure 4. 1 Northeast Location Map" and "Figure 4.4 Northeast Annual Precipitation and Annual Average Temperature Distribution Map", the climatic characteristics of this area and its influence on agricultural production are summarized. In the teaching of this knowledge point, we should pay attention to strengthen the guidance for students to read and analyze maps, cultivate students' ability to use maps, and inspire students to think about how to develop agricultural production from factors such as precipitation, temperature and heat.
2. Topography and soil conditions: The textbook first introduces the agricultural development direction of different landforms, and then explains the topographic structure of the northeast with the map of "Figure 4.3 Northeast Topography". Through the analysis of students' reading pictures, it is natural to get how to develop the agricultural structure in Northeast China according to local conditions. The purpose of compiling teaching materials is to cultivate students' ability to read pictures and transfer knowledge.
3. Socio-economic conditions: The textbook analyzes the influence on agricultural production in Northeast China from the aspects of market, traffic, population and development history.
The purpose of the content arrangement of "activities" is to make students better understand the agricultural development of a region through the analysis of the geographical conditions in Northeast China, which must rely on the local natural background, geographical conditions and socio-economic factors. Through students' discussion and exploration of "activities", we can cultivate students' knowledge transfer and application ability and learn to think, analyze and solve problems.
The second topic: the characteristics of agricultural layout, from the climate, landform, vegetation, soil and other factors to analyze the differences in agricultural natural conditions between the east and the west of Northeast China, and divide Northeast China into three major agricultural producing areas. In teaching, we should make full use of Figure 4.4 and Figure 4.5 to guide students to analyze and think about the changing law and reasons of precipitation temperature difference between north and south and east and west in Northeast China. Comprehensively compare the production characteristics of the three major agricultural areas.
The purpose of activity 1 is to let students learn to sum up knowledge, consolidate knowledge and cultivate their language expression ability through student activities.
The purpose of activity 2 is to make students understand the natural and social conditions that affect agricultural production, and realize that the development of scientific and technological conditions can change the restrictions of natural conditions on agricultural production.
Activity 3 By comparing the characteristics of animal husbandry in developed countries, we found the problems existing in the development of animal husbandry in Northeast China and even the whole country, and thought about the strategy of sustainable development of animal husbandry.
Topic 3: Large-scale specialized production-commodity grain base construction, which illustrates the characteristics of agricultural production in Northeast China-the land area and the number of machinery owned by large-scale mechanized production through Heilongjiang. Use Figure 4. 10 Distribution of Commodity Grain Bases in Northeast China to introduce the formation of specialization in the preliminary division of agricultural production in Northeast China. In this part of knowledge, we can introduce and compare the characteristics of mechanization, regionalization and specialization of agricultural production in the United States, so that students can deepen their understanding of mechanization, regionalization and specialization of agriculture, thus understanding the differences between modern agricultural production in China and developed countries and strengthening national education.
Title IV: Direction of agricultural development. By analyzing the present situation of agricultural production and the sustainable development of agriculture in Northeast China, we must start with improving the agricultural ecological environment, adhere to the combination of development, utilization, management and protection, and adhere to the requirement of unifying economic benefits and ecological benefits. Stimulate students' desire to explore the direction and key points of agricultural development in different regions of Northeast China, and lay the foundation for telling the development of the three major agricultural regions in Northeast China.
