- Abstract:
- The level terraced field controls slope cultivated land soil erosion and realizes the drought agricultural high yield and one of the steady essential measures, the terraced fields construction of our country has already had a history of several thousand years, through analysing and summarizing existing materials, it was observed by fixed position the change rule of space-time of the soil moisture of level terraced field in Pengyang county, and it analyses and explains rule that 4 levels and 3 periods of soil moisture seasonal variation and vertical changes for terraced fields, providing reference for crop cultivation.
