- Abstract:
-
Soil disintegration is an important index to measure soil erosion and an important basis for soil erosion control. In this paper, observing 1-year and 9-year red soil of peach orchards in the hilly area in northern Guangdong Province were taken as the examples, the characteristics of soil disintegration was determined by the means of hydrostatic disintegration. The results show that:(1)the cumulative disintegration index and disintegration rate of soil at various points are significantly different, but both present the trend of rapid rising first and then slow declining with the disintegration process;(2)the soil disintegration rate at various points generally decreases with the increase of soil depth;(3)the cumulative soil disintegration index and disintegration rate of 9-year peach garden are lower than that those of 1-year peach garden;(4)soil disintegration rate decreases with the increase of bulk density and water content. This study can provide reference for the improvement of the disintegration resistance of red soil and preventive treatment of oil erosion in hilly area of red soil orchards.
