安口流域土壤的肥力状况及推荐施肥
- Title:
- Recommended Fertilizing and Soil Fertility Status in Ankou Valley
- 分类号:
- S153.6
- 摘要:
- 针对安口流域内土壤肥力水平低且养分比例失调的实际状况，按土地利用方式及地形部位每2～3hm2面积采集一个土壤样品，用常规分析方法测定了土壤有机质、有效氮、有效磷、有效钾、有效铜、有效锌等养分指标，编制了土壤养分丰缺对照表，对各测定项目进行了系统评价，并作了相应的推荐施肥建议。
- Abstract:
- Based on the facts of low soil fertility and unbalanced nutrient ratio in Ankou valley, one soil sample was collected per 2 to 3 hm2 according to the land use pattern and the relief determinant.The soil nutrient indices, such as soil organic matter and available N, P, K, Cu, Zn were measured using routine analytical method.A contrast table of adequate or inadequate of soil nutrients was compiled to provide a systematic evaluation of indicators measured and some corresponding suggestions about recommended fertilizing.
