End time of intensive cultivation

Intensive cultivation is not completely over.

Agriculture can be divided into different historical forms, such as primitive agriculture, traditional agriculture and modern agriculture, which have evolved in turn. The use of wood and stone farm tools and the cutting of farm tools play an important role. Slash-and-burn farming system is the main feature of primitive agricultural production tools and technologies, which is basically consistent with Neolithic archaeology.

Traditional agriculture is marked by the use of animal-drawn or human-operated metal tools, and the production technology is based on intuitive experience, taking Niu Geng as a typical form. China entered the class society in the Xia Dynasty over 2000 BC, and the Yellow River basin gradually changed from primitive agriculture to traditional agriculture. Since then, China agriculture has gradually formed the tradition of intensive cultivation.

Intensive cultivation in agriculture

From the overall analysis of agriculture, agricultural technical measures can be divided into two parts, one is to adapt to and improve the environmental conditions of agricultural biological production, and the other is to improve the production capacity of agricultural organisms themselves. China agricultural intensive cultivation technology system includes these two technical measures.

The ancients in China summarized the environmental conditions of agricultural production as "heaven" and "earth". The so-called "heaven" of the ancients, especially in agricultural production, mainly refers to climate, which is also called "time" or "time" because climate change shows a certain time sequence.
