Introduction to agriculture:
Agriculture is an industry that uses the growth and development laws of animals and plants to obtain products through artificial cultivation. Agriculture belongs to the primary industry, and the science of studying agriculture is agronomy. The working objects of agriculture are plants, animals and other organisms, and the products obtained come from the organisms themselves, such as silk and musk. Agriculture is the basic industry supporting the construction and development of national economy.
Paddy field is the main farmland in southern China, and rice is the main food crop. Farmland in northern China is mainly dry land, and wheat is the main food crop. The northern part of the Qinling Mountains to the north of Huaihe River in China belongs to temperate monsoon climate, with low heat and little precipitation. Mainly planting dryland crops, mainly wheat.
Origin:
Agricultural production is closely related to climate resources, and superior climate resources are an important condition for the birth of agricultural civilization. Climate elements mainly include temperature, precipitation and light. China is located in the east of Asia-Europe continent and the west coast of the Pacific Ocean, with great differences in thermal properties between land and sea, forming the most typical monsoon climate in the world.
Monsoon climate is the main feature of China climate, which is a mixture of continental climate and maritime climate. In winter, affected by the dry and cold air flow in the inland, the weather is cold, dry and rainy; In summer, it is hot, humid and rainy because of the warm and humid air currents in the ocean. The high temperature period is consistent with the rainy season, and the water and heat are well coordinated, which is very beneficial to the growth of crops.
The precipitation in the middle and lower reaches of the Yellow River in China is mainly concentrated in summer, which has the characteristics of "rain and heat at the same time". Abundant sunshine, high temperature and abundant rainfall are superior climatic conditions in the middle and lower reaches of the Yellow River in China, which are suitable for crop growth. As early as ancient times, farming civilization was born here, which is the earliest area in China, and the 24 solar terms also originated from it.
For decades, archaeologists in China have been exploring the origin of agriculture as an important academic topic, and have conducted investigations and excavations in Jianghuai, Hehan and Han basins and vast areas, and found a number of sites, such as Zhupiyan in Guilin, Guangxi, Wannian Fairy Cave in Jiangxi, Cishan in Wu 'an, Hebei, Peiligang in Xinzheng, Henan, Nanzhuangtou in Xu Shui, Hebei, Pengtou Mountain in Lixian, Hunan and other places.
The first two sites are about eight or nine thousand years ago. Wu 'an Cishan site and Xinzheng Peiligang site are also earlier than Yangshao culture in the Central Plains, seven or eight thousand years ago.
