- Title:
- THE ASSESSMENT OF SOIL RESOURCES AND ITS IMPROVMENT AND UTILIZATION SHANGHUANG VILLAGE OF GUYUAN COUNTY
- 摘要:
- 本文研究了上黄村土壤的物理、化学性质和各种土壤的分布规律。通过综合对比分析，将上黄村土壤资源肥力状况分为三级：(1)肥力总指数>40；(2)肥力总指数40—35；(3)肥力总指数35—23。又根据土壤分布和组合的特点提出了六个改良利用片：(1)首批建设成高产稳产农田片；(2)逐渐建设成高产稳产农田片；(3)台、坪坡地农牧利用片；(4)农牧综合利用农田片；(5)旱生草灌利用片；(6)林地利用片。本研究为宁南黄土丘陵区农林牧优化生态经济结构提供基本依据。
- Abstract:
- Shanghuang village is located in loess hilly of eastern part of Guyuan county.Through comprehensive analyzing and overall assessing soil resources in Shanghuang village,the soil fertility condition were divided three types: 1.The total index of fertility >40,belong to higher fertility,where farming is mginly developed. 2.The total index of feritlity 40—35,belong to medium fertility,where grass is mainly developed. 3.The total index of fertility 35-20,belong to lower fertility, where fruit and foresty planting are mainly developed.According to the principles mentioned above,6 areas were divided.
