Influences of cultivation patterns (one-row ridge and double-row ridge) on micro environment of field and potato yield

To figure out influences of cultivation patterns on micro environment and yield of potato, two ridge styles (one-row ridge and double-row ridge) were studied by using field investigation method. Changes of environmental factors including soil temperature, soil humidity, photosynthetic capacity and yield of potato were detected. The results showed that compared with the one-row ridge, the yield and the rate of commodity product of potato were lower under the double-row ridge, but efficiency rainfall and soil moisture would be better if it was short of the effective precipitation. No obvious change rule was found on chlorophyll content and photosynthetic rate of detached leaves under the tested ridge styles. Under the tested ridge styles, potato growing was infected also by other aspects and the mainly negative effect was from the double-row ridge style.
