| 摘 要： | 研究了保持耕作技术对治理旱区坡耕地水土流失的作用,表明高留茬深松技术可以减少降雨中的产流次数及径流量,大幅度降低径流量中NO_3~--N的浓度及流失量,在土壤侵蚀中氮和钾具有养分富集作用,而磷的流失仅与流失的土壤总量有关。

| Abstract: | This research seted forth function and position of conservation tillage in harnessing soil and water loss on slope fields in dry-lands. High leave stubble subsoiling can reduce times and quantity of runoff,and the technology can also lower marvelously consistence and loss of NO3--N in runoff. N and K have effect of nutrient richment in soil erosion. P loss was not concerned with total soil loss. |
