Abstract:

The effects of ridge cultivation pattern on potato growth, photosynthesis and yield were explored to provide a scientific basis for the popularization and application of ridge cultivation without film mulching in dry land of shallow mountainous area in Qinghai Province. In the 2-year positioning experiment, the treatment of ridge cultivation without plastic film mulching was set up, and the control treatment was the ridge cultivation with plastic film mulching. The growth, photosynthesis and yield of potato under different treatments were analyzed. The results showed that there was no significant difference of plant height, leaf chlorophyll content, leaf photosynthetic characteristics, yield and commodity rate between the treatments. In the dryland of the shallow mountainous area in Qinghai Province, the ridge cultivation without film mulching can be popularized and applied in potato production, but it still needs multi-point verification to control the risks.

Key words: ridge cultivation, no film mulching, potato, Qinghai, dry land in the shallow mountainous area
