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。
In this paper, the physical and chemical properties of soils and the distribution of various soils in Shanghuang village were studied. Through comprehensive comparative analysis, soil fertility in Shanghuang village is divided into three levels: (1) total fertility index> 40; (2) total fertility index 40-35; (3) total fertility index 35-23. According to the characteristics of soil distribution and combination, six improved utilization tablets are proposed: (1) The first batch of high-yield and stable-yield farmland pieces is constructed; (2) The high-yield and stable farmland pieces are gradually built; (3) ; (4) agricultural and pastoral comprehensive utilization of farmland tablets; (5) dry grass irrigation and utilization tablets; This study provides the basic evidence for optimizing the eco-economic structure of agriculture, forestry and animal husbandry in the loess hilly region of southern Ningxia.
