摘要:
通过小试验区水土流失动态监测及耕作措施推广表明,耕垦指数较高的丘陵地区,坡耕地是水土流失的主要原因,坡耕地每公顷年径流量达1865.1m3,泥沙流失量达492.9t。改传统顺坡种植为横耕间作套种,地表径流减少48%,泥沙流失减少62%,养分流失减少16.5%,粮食单产增加20%,耕作措施是丘陵区防治水土流失的有效措施,可以推广。
Abstract:
Through the dynamic monitoring of soil and water loss in experimental plot and the popularization of farm practice, it is indicated that slope cropland is the main cause of soil and water loss in the hilly area, in which the reclamation index is higher. It is a effective control measurement of soil and water conservation to turn the conventional straight-line cropping into cross-contour cropping with inter-planting.
