Differences and relations between terraced fields in Yunnan and rice production patterns in Northeast China

The differences and connections between them are as follows:

Difference:

1. Geographical environment: Yunnan terraces are located in the mountainous areas of Yunnan, and the terrain is mostly steep. Terraces are built to adapt to mountain agriculture. Northeast China is mainly plain and hilly area, which is suitable for rice planting.

2. Selection of rice varieties: Yunnan terraces mainly plant alpine rice, which is adapted to high altitude, cold and rainy environment and has the characteristics of cold tolerance and seedling weight tolerance. Ordinary rice and japonica rice are mainly planted in Northeast China to adapt to low altitude and climate characteristics.

3. Water conservancy facilities: Yunnan terraces solve the water source problem of mountain agriculture by building water conservancy facilities such as terraced stone dikes and irrigation channels. However, most large-scale water conservancy projects in Northeast China, such as diverting water from the Yellow River to Liaoning and Huaihe River to Liaoning, are used to solve the water problem.

Contact person:

1. Rice planting: Rice planting is the main crop in both terraced fields and northeast rice areas in Yunnan. Rice is the main food crop, which requires high moisture and temperature, and needs paddy field or similar environment to grow.

2. Water irrigation: No matter the terraced fields in Yunnan or the rice fields in Northeast China, reasonable water irrigation is needed to ensure sufficient water supply for rice fields. Terrace irrigation and large-scale water conservancy projects are all aimed at solving the water problem in rice production.

3. Farming culture: Yunnan terraced fields and northeast rice-growing areas have rich traditions of farming culture, and people have accumulated experience and technology in growing rice in practice, forming characteristic farming culture and traditional customs.
