- 摘要:
- 土壤崩解特性是衡量土壤侵蚀的重要指标,是防治土壤侵蚀的重要依据。以粤北红壤丘陵区1年生与9年生桃园土壤为研究对象,采用静水崩解法测定土壤崩解特性。结果表明:(1)各样点土壤累积崩解指数与崩解速率差异较大,但均随崩解时间呈现出先快速增加后缓慢降低的趋势;(2)各样点的土壤崩解速率大体表现为随土层深度的增加而降低;(3)9年生桃园累积土壤崩解指数与崩解速率均低于1年生桃园;(4)土壤崩解速率随容重和含水量的增大而减小。研究为提高红壤抗崩解性提供参考,为红壤丘陵区果园土壤侵蚀防治提供一定的依据。
- 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.
