- 摘要:
- 重庆地区的山地茶园，在坡地等高种植的情况下，土壤年均侵蚀量在3198～27186 kg/hm2之间，随着坡度的增大，土壤侵蚀愈为严重，二者呈显著正相关；提高茶园土壤覆盖度可显著降低其水土流失量；梯型种植再辅以复合种植，是减少茶园中水土流失的最佳模式，其5～25°的茶园土壤年均侵蚀量在964.5～2613 kg/hm2之间，显著低于侵蚀标准
- Abstract:
- Under the condition of the same height planting,the annual average amount of soil erosion ranges from 3 198 to (27 189 kg/hm2)in hilly tea farm of Chongqing.With the rising of slope,the soil loss is more serious.Raising the rate of ground cover could reduce the amount of water and soil loss greatly;ladder-shaped planting with compound way was the best model reducing water and soil loss.In this way,the annual average amount of soil erosion in tea farm,a slope from 5°to 25°,ranges from 964.5 to 2 613 kg/hm2.It was lower than erosion standard significantly.
